Как просужить погреб в гараже от конденсата: виды вентиляций, полезные советы

Чтобы максимально использовать пространство, многие владельцы гаража обустраивают там погреб для хранения продуктов питания. Но если не организовать правильную систему вентилирования, запасы будут быстро портиться от повышенной влажности и отсутствия свежего воздуха. Как должна быть устроена вытяжка для погреба в гараже и как сделать ее собственными руками, разберемся в статье.

Для чего нужна вытяжка в погребе в гараже

Для начала нужно понимать, зачем нужна вентиляция в погребе. Для этого есть целый ряд причин:

1. Если не будет обмена воздуха, в помещении быстро начинает появляться конденсат, который увеличивает влажность воздуха. Это приведет к порче продуктов, появлению грибка и плесени.
2. В холодное время года температура воздуха в подземном помещении будет на порядок выше, чем в гараже. При отсутствии вытяжки теплый и влажный воздух будет подниматься из погреба наружу и провоцировать коррозию железа, что очень опасно для автомобилей.
3. Если не сделать вытяжку, то продукты со временем станут токсичными и непригодными для употребления. Вредные испарения от машины, запахи разных химических жидкостей, резины и прочего будут пропитывать запасы.

Чтобы не было конденсата – нужна вытежка

Именно потому система вентиляции погреба гараже должна предусматривать устранение воздуха из ямы и поступление свежего внутрь.

Виды вентиляции

Есть несколько видов вентиляции, которая может быть установлена в подвале:

1. Естественная вентиляция в погребе гаража. Такой вариант — самый доступный и простой способ проветривания помещения. Но летом такое устройство не работает, а зимой нужно постоянно проверять вентиляционные каналы и контролировать их состояние.
2. Комбинированная вытяжка обеспечит хороший воздухообмен. Она отличается от естественной только тем, что возле одного из воздуховодов есть вентилятор, который оказывает дополнительное сопротивление потоку воздуха. Конечно, он не должен быть включенным постоянно. Используйте вентилятор только в тех случаях, когда нужно проветрить помещение. Преимущество комбинированной вытяжки в том, что она одинаково эффективна в любое время года.
3. Принудительная вентиляция производится за счет постоянной работы вентилятора. Такой способ более затратный, поскольку предусматривает постоянное потребление энергии. К тому же монтировать систему достаточно тяжело, и не каждый хозяин сможет сделать это самостоятельно.

Какой из вариантов выбрать, зависит от личных предпочтений, размера погреба и объема продуктов, которые в нем находятся.

В данном видео вы узнаете, как сделать сухой подвал:

Устройство естественной вентиляции

Естественная вентиляция относится к самым простым способам осушения подвала в гараже. Чаще всего ее используют, если помещение не очень большое. К тому же ее просто сделать собственными руками.

Но такое устройство вентиляции в погребе гаража требует постоянного контроля, ведь трубы легко забиваются мусором, снегом или опавшими листьями. Во время установки системы важно знать несколько аспектов:

1. Приточная и вытяжная трубы должны располагаться в противоположных углах помещения.
2. Приточная труба не должна быть выше, чем 30-50 см от пола, а вытяжная – 150-200 см.
3. Если вытяжная труба устанавливается с наружной части, ее следует утеплить.
4. Входное отверстие закройте мелкой сеткой. Это убережет от мелких грызунов и насекомых, которые могут попасть в погреб.
5. Накройте вытяжку козырьком, а лучше диффузором, который будет увеличивать тягу.
6. Чтобы понять, какой диаметр приточной трубы понадобится, нужно умножить площадь гаража на 1,5. При этом первое значение берется в квадратных метрах, а результат – в сантиметрах.
7. Вытяжная труба не должна быть большого размера. Специалисты считают, что достаточно будет диаметра, равного десятой части от размера приточной.

Чтобы разобраться было проще, составьте схему до начала работы в гараже. Учитывайте, что труба должна быть максимально ровной. Каждый ее изгиб значительно снижает эффективность всей системы вентилирования.

Организация принудительной вентиляции

Лучший способ, как просушить погреб в гараже, – установить принудительную вентиляцию. В таком случае воздух будет нагнетаться внутрь помещения, проходить фильтрацию, а также подогреваться или охлаждаться в зависимости от температуры снаружи.

Такая система лучше всего поможет высушить конденсат или влагу после затопления погреба. Организуют принудительную вентиляцию с помощью встроенных в трубу вентиляторов. В остальном схема вентиляции погреба в гараже практически не отличается от предыдущего варианта.

Но этот способ имеет и свои недостатки:

1. Нужно провести проводку в трубы, а это – дополнительные затраты и работа.
2. Система содержит много деталей, которые периодически будут выходить из строя и требовать замены.
3. Будет постоянный расход электроэнергии.

Вентиляция гаража с погребом с ямой, выполненная таким способом, будет быстрой и качественной.

Данная вентиляция имеет ряд недостатков

Перед тем как приступать к работе, нужно обдумать все нюансы. Сначала определитесь с местом, где будет расположен вентилятор. Его нельзя ставить на концах трубы, поскольку прибор выйдет из строя при попадании влаги. К тому же вентилятор довольно шумный, что может доставлять дополнительный дискомфорт.

Получается, что можно сделать монтаж в трубе, в месте, где происходит забор воздуха, или выбрать канальный вентилятор. На начальном этапе установка ничем не отличается от естественной: устанавливаются две вентиляционные трубы в противоположных углах на разной высоте.

Далее в трубу встраивается вентилятор. В это же время укладывается кабель, чтобы запитать устройство. Остается только монтировать выключатель, и система готова к использованию.

Часть трубы, которая находится на поверхности, нужно закрыть мелкой сеткой, и оборудовать козырек.

Устройство комбинированной вентиляции

Еще один вариант, как избавиться от влаги в погребе, – установить комбинированную вентиляцию. Она поможет эффективно просушить помещение подвала и избавить его от застоявшегося воздуха.

Чтобы сделать комбинированную вентиляцию, достаточно установить обычную лампочку в вытяжной трубе. Именно она будет подогревать воздух и дополнительно усиливать тягу.

Раньше для этого способа использовали свечку. Но такой вариант ненадежен и весьма опасен.

Устройство естественного воздухообмена

Естественная вытяжка состоит из ряда составляющих:

1. Входная труба, через которую чистый и свежий воздух будет попадать внутрь погреба. Чаще всего она имеет диаметр от 10 до 25 см.
2. Выходная труба, через которую воздух будет покидать помещение. Ее диаметр будет немного меньше.
3. Резервуар, в который будет собираться конденсат.
4. Мелкая сетка, которой закроется наружная часть трубы.
5. Конусный козырек.

Перед тем как сделать вытяжку в погребе гаража, проведите теплоизоляционные и гидроизоляционные работы. Лучше всего это делать еще на этапе строительства подвала.

Вентиляция гаражного погреба своими руками

Вентиляцию в погребе в гараже можно сделать своими руками. Монтаж условно делят на несколько этапов:

1. Работа с вытяжным воздуховодом. Система вентиляции должна работать правильно, поэтому нижний конец трубы нужно зафиксировать в 1.5-2 метрах от пола. Внешняя же часть выводится наружу, за пределы подпола. При этом верхняя точка будет выше уровня грунта на 0,5 м.
   Есть два способа для установки вытяжной трубы. Если использовать сквозной вариант, то трубу нужно будет провести насквозь, через гаражный пол, в само помещение, и вывести через потолок и кровлю основного сооружения.
2. Есть еще один вариант, который называется «сквозь стену». Если использовать его, нижняя часть вентиляционной трубы будет расположена вертикально и выходить не через верх, а через боковую стенку основного здания, и подниматься вверх параллельно основному строению.
   

   В таком случае у основной трубы будет залом, что значительно усложняет не только забор воздуха, но и его очистку.

3. Установка приточного воздуховода. Для этого следует ввести трубу в противоположный угол от вытяжки. Далее укрепите ее на расстоянии около 50 см от пола погреба. Противоположный конец трубы также выводится наружу. Он должен находиться на высоте не более 20 см от уровня земли. Так он лучше всего будет забирать воздух.
4. Проверьте воздушную тягу. Сделать это просто с помощь обычной зажженной спички.
5. На конце каждой из труб закрепите мелкоячеистую сетку. Именно она убережет от засорения труб и попадания в них насекомых, мелких грызунов и птиц.

Чтобы продлить срок службы трубы, соорудите небольшие козырьки над каждым из выходов. Такие простые манипуляции помогут сберечь основание от жаркого солнца, дождей и снега.

Не забываем следовать инструкции создания вентиляции

Даже когда работает правильная вытяжка, образуются капельки конденсата. Для них устанавливается специальная емкость, в качестве которой может служить небольшая миска или ведерко.

Важно не только знать, как правильно сделать вытяжку в погребе, но и интересоваться новыми разработками. К примеру, новые заслонки. С их помощью можно легко контролировать воздухообмен в подвале, что особенно важно в зимнее время. Как только температура на улице опускается ниже нужного уровня, следует просто закрыть их, и морозный воздух не сможет проникнуть в помещение, испортив продукты, которые в нем хранятся.

Механизированный тип вентиляции

Самым новым и действенным способом, с помощью которого просушивают погреб в гараже, остается механизированный. В таком случае за циркуляцию воздуха полностью отвечает моноблок, который и провоцирует движение.

Программное обеспечение, которое в нем установлено, управляется с помощью модульной системы. Именно потому этот агрегат называют самым надежным на данный момент.

Единственный недостаток системы в высокой стоимости. Не каждый хозяин готов выложить несколько тысяч для обеспечения нормальной циркуляции воздуха в подсобном помещении.

Если планируется загружать подвал продуктами максимально и часто пользоваться его помещением, то лучше сделать все капитально, чтобы потом не жалеть о пропавших запасах.

В заключение

В статье мы рассмотрели основные виды вытяжек, которые можно установить в погребе, находящемся в гараже. Какому из перечисленных вариантов отдать предпочтение – дело каждого. Важно учитывать размер помещения, насколько часто оно будет использоваться.

С помощью описанных выше характеристик и рекомендаций каждый сможет оборудовать собственный подвал отличной вентиляцией. К тому же сделать это можно собственными руками, не прибегая к услугам специалистов.

90000 Root Cellars 101- Root Cellar Design, Use and Mistakes to Avoid 90001 90002 Sharing is caring! 90003 90004 90004 90002 In this article we’ll talk about 5 basic things you must include in a root cellar design, plus 10 tips for fruit and vegetable storage. There’s also a printable storage guide for over 30 fruits and veggies, and links to additional information at the bottom of the post. 90003 90002 A root cellar is a great low-cost way to store food — not just root vegetables, but other fresh produce, too.They require little to no energy to use and very little maintenance. 90003 90002 You can build in a root cellar when your home is under construction, but it’s also possible to add a root cellar to your basement, or build one outside your home. 90003 90012 90012 90014 What is a root cellar? 90015 90002 Wiki says a root cellar is «90017 a structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods. 90018 «90003 90002 Dig a deep enough hole, and you’ll find that the ground is cool (and often moist).Root cellars tap into those cool, moist soil conditions and use them to store fruits and vegetables — like your refrigerator produce bin. 90003 90014 Building a Root Cellar 90015 90002 There are five major elements that a root cellar requires: 90003 90026 90027 90028 Ventilation: 90029 Some fruits and vegetables give off ethylene gas, which can cause other produce to spoil. Also, a tightly sealed cellar will increase the risk of mold. Make sure fresh air can get in, stale air can get out, and air can circulate around the produce.90030 90027 90028 Earth-shelter: 90029 The soil insulates and maintains a cooler temperature. A packed earth floor or gravel floor is better than concrete for keeping moisture (humidity) levels higher. 90030 90027 90028 Humidity: 90029 A high humidity level of 80-95% keeps produce from drying out. Humidity that is high enough for produce may cause canning jar lids to rust, so be sure to check lids and rotate stock if you store canned goods in the root cellar. Too much humidity can be a problem also, so try to keep it below 95% 90030 90027 90028 Darkness: 90029 Light can trigger sprouting, so if you have a window in your root cellar, keep it covered, and do not leave the lights on.90030 90027 90028 Shelving / Storage bins: 90029 Wood shelving and bins are naturally antibacterial. Wood also conducts heat more slowly than metal, and does not rust. Avoid treated wood, and stick to those that are naturally rot resistant. 90030 90047 90014 Types of Root Cellars and Natural Cold Storage Options 90015 90002 Natural cold storage options include (click on any item in the list to jump to more information below): 90003 90002 All of these keep your food cool. These earth sheltered fruit and vegetable options work best for those in cooler climates, where the ground temp is naturally cooler.90003 90014 Warmer Climate Options 90015 90002 You may not be able to store things like we northerners can, but the Above Ground Root Cellar post will give you some ideas of what you can store, plus tips for year round food production so you always have fresh , local food to enjoy. The Coolbot makes it very affordable to use a standard AC unit for refrigerated fruit and vegetable storage. 90003 90002 Check out the related articles 90003 90014 10 Tips for Fruit and Vegetable Storage in a Root Cellar 90015 90002 Key storage tips to remember: 90003 90026 90027 Late-maturing crops store better than early maturing crops.Specific varieties also store better than others. Watch for varieties that are noted for good storage quality. 90030 90027 Check fruit and vegetable condition at storage time. If you note any damage on produce, use those items first. One bad apple or onion can spoil the whole bin, so it’s good to regularly inspect produce during storage, too. 90030 90027 Cure the vegetables that need it before storage. Vegetables that require curing include onions, garlic, winter squash (pumpkins), potatoes and other root crops.90030 90027 Most root vegetables store best in the root cellar if they are wiped off rather than washed. Wipe excess dirt off of carrots, beets, rutabagas and turnips and store them in lightly dampened leaves or straw. Use fresh leaves each year to prevent potential pathogen buildup. Fresh sand and sawdust will also work, but are messier. 90030 90027 If you have a muddy garden at harvest time, it’s okay to wash, but make sure dry up excess moisture (and cure if needed) before storage to avoid rot.Humidity is good, water on the surface of fruits and vegetables is not. 90030 90027 Less-than-ideal conditions shorten storage life. Try to get as close as possible to target temps and moisture levels. Use different areas of your storage for crops that are a best fit, such as storing carrots and beets lower (colder) and tomatoes and winter squash higher (warmer). (See Fruit and Vegetable Storage chart below.) 90030 90027 Store fruits that give off ethylene gas away from produce that can be spoiled easily by ethylene gas.You can also wrap fruit that produces excess ethylene in newspaper to contain the gas. 90030 90027 The odor of strong smelling vegetables, like turnips and cabbage, can be absorbed by fruits and other vegetables. Store them away from other food and where the odor can not waft into the house. 90030 90027 90028 Do not allow fruits and vegetables to freeze. They will get mushy and rot. 90029 90030 90027 Track temperature and humidity to measure your root cellar performance. Do not open the root cellar unless you have to, unless the entry is protected.Letting heat in or very cold dry air in will reduce the storage life of your fruits and vegetables. 90030 90047 90088 Fruit and Vegetable Storage Chart 90089 90002 This chart gives preferred temperature and moisture ranges for root cellar storage of a variety of fruits and vegetables. 90017 Adapted from the 90018 90017 University of Missouri Extension Office 90018 90017. 90018 90028 Click 90029 90028 HERE 90029 90028 or on image below to download Printable PDF version of Root Cellar Storage Requirements.90029 90003 90104 90104 90014 Root Cellar Location — In the Basement or Buried Outside? 90015 90002 By default, the word «cellar» means «underground». A big part of why root cellars work as well as they do is that the earth remains at a relatively constant (cool) temperature. 90003 90002 Underground temperatures vary, depending on your location. Closer to the equator, it may be cooler than air temp, but still is not likely to act well as a root cellar in Canada. At the opposite extreme, you have arctic permafrost, which the native folks use to store whole animals.90003 90088 Retrofitting a Root Cellar in an Existing Home 90089 90002 The easiest option for building a root cellar is to section off a part of the basement for your fruit and vegetable storage. Old dirt floor basements without heat are great for maintaining proper temperature and humidity levels (be sure to insulate between the house and root cellar). 90003 90014 Add a Root Cellar to a New Home 90015 90002 Many new homes have a small concrete exterior porch. Typically this area has 4ft footings and is filled under the porch with dirt.You need to put a foundation wall under it anyway, so why not put this area to good use? 90003 90002 To turn this under porch area into a root cellar, have the builder put in full footings, an insulated exterior grade access door from the basement and two 4 inch vent holes. Add concrete slab on top as normal. This area could also be a wine cellar or safe room. It will cost more but not a lot more. 90003 90002 Add a switched light and rigid insulation on the ceiling of the root cellar. Insulate the walls to the home.Do not insulate the outside walls exposed to soil. If possible get the builder to skip insulating around that area on the exterior of the root cellar concrete. 90003 90002 Our porch root cellar measures about 6’x8 ‘. It provides plenty of room for our stash of root veggies, plus gives a nice sized porch above. Locating the root cellar outside the footprint of the home allows the root cellar to maintain cooler temperatures more easily than a cellar located within the house. 90003 90126 90126 90088 Building a Root Cellar Outside the Home 90089 90002 For an exterior root cellar, similar rules apply — have good ventilation, keep it earth sheltered and dark.A north facing door is preferred, to avoid sun beating in and heating your cellar up. 90003 90002 Try for at least one to two feet of soil covering the root cellar. Consider a pre-made option such as a septic tank or large pre-cast culvert. Otherwise use materials that are rot resistant and can stand the weight of wet soil. We do not recommend shipping containers. 90003 90088 Traditional Root Cellar 90089 90002 This is what most of us think of when we hear the phrase «root cellar». There are insulated doors that lead down into the earth.It’s dug down or into the side of a hill. 90003 90002 Walls are concrete, cinder block, or more creative materials like old tires. You need to make sure the roof and walls are well supported to avoid collapse. Engage an architect or engineer to ensure your safety. 90003 90088 Earth Berm Root Cellar 90089 90002 Above ground root cellars are usually partly sunken with earth mounded on 3 sides and the door avoiding the direct sun. See the Above Ground Root Cellars post for more information. 90003 90002 For a great resource on building a homestead root cellar, check out the book below by my friend, Teri, of Homestead Honey.90003 90002 Select an area with an existing window if possible, and use the window for ventilation. Fill the window with exterior grade plywood, and cut the necessary vent holes through the plywood. The plywood also blocks direct light. 90003 90002 North facing corners work well, because you can leave the two exterior walls uninsulated, and only insulate the interior walls and ceiling. A north facing wall will not gain heat from the sun. Use materials that tolerate moisture exposure. 90003 90002 Insulating between the house and root cellar is necessary so you do not heat the root cellar from above.You also avoid losing house heat into the root cellar. 90003 90002 Your basement root cellar should have no standard heating or cooling. Insulate any ductwork or piping that runs through the ceiling above your root cellar (if any). Make sure vents or hot water pipes are well insulated so they do not bleed heat into your root cellar. 90003 90002 For additional food storage space, build shelving on the inside and outside of your basement root cellar for canned goods or other items. The area outside the root cellar can be used to store dry goods and canned goods if it is cool enough.90003 90088 Barrel in the ground for (Zones 6-9) 90089 90002 The size and depth depends on the zone you live in. A simple bucket, with holes drilled in the bottom and top, buried level with the soil with a bale of hay as an insulating cover will work into zone 7 and possibly into zone 6 depending on cover and conditions. The colder and hotter zones require the bucket or barrel to be deeper, and more insulation on the top to avoid the freezing surface temps. 90003 90002 For more information on zones see: Plant Hardiness Zones & Microclimate — Creating your Best Garden 90003 90088 Barrel in the ground for (Zones 3-6) 90089 90002 Buy one 55gal large heavy duty garbage can, and a 32gal smaller garbage can that fits inside the larger one (with an inch or two gap).Both the larger garbage can and the smaller one need holes in the bottom. 90003 90002 The inside can needs a cover with vents / screen. Cover exterior holes with screens to keep rodents out. It also needs significant insulation above it (over it). Bales of hay, or piles of leaves can insulate it. 90003 90002 Prepare a hole that is deeper than the large garbage can, with rocks and gravel in the bottom to create a simple French drain. If water drains well, you will need a small amount of rocks and gravel.If you have clay or your soil does not drain well, you need to go deeper and wider so your underground storage barrel does not turn into a water hole. 90003 90002 Another trick is to dig a very deep, large hole next to the garbage can hole and fill that hole with rocks. The deeper hole acts as a drain for your shallower garbage can root cellar. 90003 90002 Once you have the large garbage can in the ground and secure, lower the smaller one into the larger barrel. Store food in the small barrel. 90003 90002 When you need access, grab from the top or pull out the smaller barrel.This makes it easier to reach food the bottom. There are many variations on this. 90003 90176 90176 90014 Root Cellar Ventilation 90015 90002 Improper ventilation is one of most common mistakes that people make when designing / installing a root cellar. They build their underground food storage airtight to keep things nice and cold, and everything spoils. 90003 90002 This is bad because some foods give off ethylene gas, which speeds ripening (and rotting). A root cellar that is too airtight may also build up excess humidity, leading to mold and mildew.90003 90002 How should you ventilate your root cellar? Use two vents, about 3-4 inches in diameter. Place the vents so that one is near the top of the root cellar to exhaust stale air and ethylene gas. The other vent should be run down to near the floor, to drop in fresh air. 90003 90002 Four inch PVC vent pipes should be adequate for to up to around an 6ft by 8ft room. A larger room like a 8ft by 10ft should have even larger vent pipes or more of them. Make sure to put mesh screen on the outside of the vent pipe to keep mice and other small animals out.Also vent pipes should be angled or curved so rain, snow or debris can not fall into your root cellar. 90003 90088 Ethylene Gas 90089 90002 As fruits such as apples and pears ripen, they give off ethylene gas. Ethylene gas decreases the storage life of some produce. Ethylene gas can cause sprouting, decay, mold, yellowing, shrinking, toughness, softness, bitterness and other damage. 90003 90002 To combat spoilage from ethylene gas, segregate fruits and veggies that produce excess ethylene gas from those that are easily damaged from ethylene gas.This is a good idea for your refrigerator produce bins, too. 90003 90088 Fruits and Vegetables that may create excess ethylene gas include: 90089 90002 Apples, apricots, avocados, ripening bananas, blueberries, cantaloupe, citrus fruit (not grapefruit), cranberries, figs, guavas, grapes, green onions, honeydew, ripe kiwi fruit, mangoes, melons, mushrooms, nectarines, okra, papayas, passion fruit, peaches, pears, peppers, persimmons, pineapple, plantains, plums, prunes, quinces, tomatoes and watermelon.90003 90088 Fruits and vegetables that may be damaged by excess ethylene gas include: 90089 90002 Asparagus, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, chard, cucumbers, cut flowers, eggplant, endive, escarole, florist greens, green beans, kale , kiwi fruit, leafy greens, lettuce, parsley, peas, peppers, potatoes, potted plants, romaine lettuce spinach, squash, sweet potatoes, watercress and yams. 90003 90088 Root Cellar Lighting 90089 90002 Light exposure is the enemy of food storage.Every time I see people lining up their canning jars or spices on open shelves, I cringe. It looks beautiful, but light bleaches out the color and the nutrient value of foods. 90003 90002 In the root cellar, light exposure may lead to sprouting and green potatoes. If you’re venting through a window, cover the rest of the window. If you have a light in your root cellar so you can see your food storage better, do not leave the light on when you’re not using it. 90003 90002 A hunk of burlap drawn over bins of potatoes or fruit will allow ventilation while still blocking the light.A single high lumen incandescent or LED light (switched on exterior) should provide adequate lighting (unless your room is really huge) and, if for some reason your storage gets too cold, you can use an incandescent light to introduce a little heat (if you keep fruits and vegetables covered). 90003 90088 Humidity and Temperature 90089 90002 A high humidity level of 80-95% keeps produce from drying out. The soil will provide some humidity. 90003 90002 Keeping track of temperature and humidity is important.You can track with a humidity with a hygrometer, and temperature with a thermometer like a Digital Hygrometer Indoor Thermometer. If you use a simple unit you will need to track temp / humidity using a paper and pencil. 90003 90002 Because you do not want to go into the root cellar except when you need to electronic monitoring might be an option. The Govee Thermometer & Hygrometer has a simply display AND can synch via bluetooth and can track 20 days. 90003 90002 The sensor and an app on your smartphone from Govee or SensorPush will record up to 20 days of temperature and / or humidity swings you might not catch because you only go in the root cellar when you need to.90003 90088 Root Cellar Humidity — Keep Things Moist But Not Wet 90089 90002 Checking the fruit and vegetable storage chart, you’ll see that most store best with fairly high humidity. If you have a dirt or gravel floor in your root cellar, you’re in luck, because the natural ground moisture will help keep your produce damp. 90003 90002 Produce will give off some moisture on its own, but if you note that your produce is shriveling, your root cellar is probably too dry. Take a tip from the grocery stores, and try a little misting action with a spray bottle.Avoid getting any area too wet, as that can lead to standing water and potential mold growth. 90003 90002 In dry environments a shallow pan, tray or shallow bucket of water can increase humidity. Be careful with this option, as it can attract pests or result in bacteria or mold growth. 90003 90228 90228 90088 Root Cellar Shelving 90089 90002 Shelving should allow airflow and add storage area. Keep a gap between the shelving or storage bins and wall to encourage air flow. Remember to check the Fruit & Vegetable Storage Chart and keep produce that likes cooler temps lower and food that like warmer 90003.90000 Above Ground Root Cellars — Enjoy Your Local Produce Longer 90001 90002 90003 August 26, 2013 90004 By Laurie Neverman 51 Comments 90005 This post may contain affiliate links which will not change your price but will share some commission. 90006 90002 Sharing is caring! 90006 90009 Keeping Local Food on the Table in Warm Climates 90010 90002 This section was written by my friend, Paula Bellman, who shares her experience as a southern gardener. 90006 90002 I live in zone 9, SW Louisiana.Because we’re so far south, we’re considered sub-tropical. We have a very high water table. Depending on where in SW Louisiana you live, you could dig down about 2 feet and you’d hit water. People do not have basements here, nor root cellars for this particular reason. 90006 90002 We are able to garden 12 months out of the year. Typically our crops in the late fall / early winter are sweet potatoes, cabbages, turnips, kohlrabi, daikon radish, regular radishes, beets, chards, kale, mustard and turnip greens.Chickens that do not sleep under artificial light will reduce their egg production dramatically in December / January. Sunrise for us is around 7:00 am and sunset would be around 5:30. Citrus fruits are typically ripe around Christmas, though some mandarin type of oranges will ripen earlier than that. Blood oranges will ripen in later January and lemons can come anytime between November and January. 90006 90002 In the early spring, we are able to harvest the tender lettuces like Bibb, romaine, leaf as well as the hardier greens like chard, mustard and turnip greens, broccoli, & cauliflower.We continue to get cabbages and root crops, but also new potatoes, red and yellow onions. Loquats come into season around the first part of March and strawberries can ripen anytime between February and April. I consider early spring to be mid-February thru end of March. 90006 90002 Food storage for fall / winter crops consist of cold storage like a working fridge on your patio or carport. We really can not do any type of room temp storage. It’s much to humid to leave things outside to dry / cure. Things need to be done inside and moved somewhere pretty quickly.Even things like fermented veggies need to go in the fridge pretty quick, or they spoil and grow mold. I have stored cabbages and onions in a dorm fridge for a good 6 months after the growing season with no problems. 90006 90002 About mid-April, it really starts to heat up. The tomatoes, cucumber, and melon plants jump up in growth and set fruits. We can usually begin harvesting the summer squash around the 1st part of May. Once the real heat hits, the squash vine beetles set in and you can not get any more squash, unless you use alternate means of pest control, which I do not.June is hot and humid with highs sometimes in the upper 90s and high humidity. Peaches and plums come ripe in late May or early June. Sweet corn comes early June along with sweet peppers, early tomatoes, and blueberries. We can or freeze tomatoes. Cantaloupes and watermelons come in June. June is my favorite month in the garden. So much delicious produce. Cucumbers will continue through July, but by then they are bitter. During the hottest part of the summer (July, August, September) basically all you’re going to get is okra, peppers, and eggplants.Figs become ripe around the 4th of July. The crop ripens basically all at once and will spoil quickly if not picked. Or the wasps get to them. Or the birds. We typically make fig preserves out of them, but some people will can them whole. 90006 90002 Our food storage options for summer veggies are: water bath canning, pressure canning, freezing, and some fermenting, like salsa. I freeze cantaloupe and honeydew melons. Watermelons can be de-seeded and pureed for juice to make jello or sorbet. Peppers can be frozen whole.I usually cook down eggplant and okra and freeze in ziploc bags. Okra and tomatoes cooked together with onions and hot peppers is really a welcome addition to a winter dinner or added to a gumbo. 90006 90002 If we’re lucky and we do not get a hurricane, we can get a second crop of tomatoes, cucumbers, and cantaloupes in October. By October, the bitter greens are coming back in as well as turnips and sweet potatoes. 90006 90002 I hope this post provides you with plenty of ideas to help keep local food on the table longer no matter where you live.You may also want to check out the book «Warm-Climate Gardening: Tips, Techniques, Plans, Projects for Humid or Dry Conditions», listed for only a penny on Amazon, if you’re gardening down south. 90006 90002 90030 Related Common Sense Home Articles 90031 90006.90000 Garage Ventilation 90001 90002 In a garage or workshop where exhaust gases like Carbon Monoxide (CO) and NO 90003 x 90004 from vehicles are very dangerous — proper ventilation is very important. 90005 90002 Garages or workshops with floor areas more than 90007 500 ft 90008 2 90009 (50m 90008 2 90009) 90012 should always have mechanical ventilation with fans.

Polluted air is evacuated through openings close to the floor and the roof. 90005 90002 For larger buildings and garages it is common to use outlet air from the ventilation systems in the surrounding buildings as fresh make-up air to the garages.90005 90002 90338 90005 90002 Air with room temperature (or temperature after the heat recovery unit) is supplied to the garage. Polluted air is evacuated through openings close to the floor and the roof. 90005.90000 CO Removal with Fan Placement 90001 90002 An estimated 1,400 cars were reduced to burned-out shells on New Year’s Eve in King’s Dock, Liverpool. Despite the development of sophisticated smoke and gas detection devices, accidents like this happen on a regular basis, placing increasing importance on garage ventilation system design. 90003 90004 Burned cars are clearly visible in what remains of the multi-story car park where a large fire destroyed hundreds of cars in Liverpool, Britain on January 1, 2018 (Source) 90002 If a fire breaks out, the garage ventilation system needs to successfully extract the smoke and gas from the garage while ensuring a safe evacuation of any people in the building and, at the same time, reducing the temperature and maintaining sufficient visibility to make the firefighters ‘job easier.Another equally important function is to maintain the fresh-air supply and extract toxic gases from the garage space to prevent the formation of «dead zones,» where harmful substances could accumulate. 90003 90002 This is the primary role of a garage ventilation system-affecting everyday user comfort, health, and safety. 90003 90009 Carbon Monoxide Removal: Why is It Important? 90010 90002 While the requirements for garage ventilation system design are generally based on different local standards, the system always needs to successfully perform two key tasks: 90003 90013 90014 Remove the pollutants emitted by cars 90015 90014 In the event of a fire, it is crucial to control the hot fumes and gases produced by the fire, protect the escape routes, and maintain ease of access for the emergency teams.90015 90018 90002 In an enclosed parking garage with an inadequate or ill-maintained ventilation system, the fumes from the cars entering, exiting and driving through the facility could build up to toxic levels. Traditional parking garage ventilation systems combine supply and exhaust fans with ductwork to push fresh air in and pollutants, smoke and harmful emissions out. The major task for them is to extract harmful exhaust gases from an underground car park, such as Carbon monoxide (CO), Nitrogen oxides (NOx) and Sulphur oxides (SOx) which cause poor air quality.90003 90002 CO concentration poses the biggest threat, causing harmful side-effects and even death, even in low quantities. It has no odor or color, but it can very quickly poison a person before they even sense anything is wrong. CO poisoning is the most common type of fatal air poisoning. If mechanical or natural ventilation is not sufficient in the enclosed environment, exhaust gas concentration is hazardous to humans and can even lead to death. 90003 90023 What International Standards Say about Parking Garage Ventilation System Design 90024 90025 90026 90027 90028 90029 CO Level in Air 90030 90031 90028 90029 Standard and Regulation 90030 90031 90036 90027 90028 90029 200 ppm 90030 90031 90028 90029 NIOSH — National Institute for Occupational Safety and Health 90030 90045 Short-term exposure limit (15-minute maximum exposure level) 90031 90036 90027 90028 90029 50 ppm 90030 90031 90028 90029 OSHA — Occupational Safety and Health Administration 90030 90045 The maximum allowable concentration for a worker’s continuous exposure in any 90045 eight-hour period 90031 90036 90027 90028 90029 50 ppm 90030 90031 90028 90029 UMC — Uniform Mechanical Code 90030 90045 Recommends activation of the mechanical ventilation when CO is monitored in a parking 90045 structure 90031 90036 90027 90028 90029 35 ppm 90030 90031 90028 90029 EPA — Environmental Protection Agency 90030 90045 Recommends 35 ppm or lower as an ambient air quality goal averaged over one hour 90031 90036 90027 90028 90029 35 ppm 90030 90031 90028 90029 NIOSH — National Institute for Occupational Safety and Health 90030 90045 PEL-TWA: 35 ppm is the maximum allowable concentration for a worker to be 90045 exposed to in any eight-hour period 90031 90036 90027 90028 90029 25 ppm 90030 90031 90028 90029 ACGIH — American Conference of Governmental Industrial Hygienists 90030 90045 TLV-TWA: 25 ppm is the maximum allowable concentration for a worker’s continuous 90045 exposure in any eight-hour period 90031 90036 90027 90028 90029 25 ppm 90030 90031 90028 90029 IMC — International Mechanical Code 90030 90045 Recommends actuation of the mechanical ventilation when CO is monitored in a 90045 parking structure 90031 90036 90027 90028 90029 9 ppm 90030 90031 90028 90029 EPA — Environmental Protection Agency 90030 90045 90029 & ASHRAE — American Society of Heating, Refrigerating and Air-Conditioning Engineers 90030 90045 Recommends 9 ppm or lower as an ambient air quality goal averaged over eight hours 90031 90036 90133 90134 90002 ASHRAE highlights the emission of carbon monoxide as one of the most serious concerns presented by car parking garages.For enclosed parking facilities, ANSI / ASHRAE Standard 62, «Ventilation for Acceptable Indoor Air Quality,» recommends 9 ppm or lower as an ambient air quality goal averaged over eight hours. Other engineering organizations set similar requirements, with 9-35 PPM maximum CO concentration over an eight-hour exposure period, and 100-200 PPM for short-term exposure. 90003 90002 Regardless of where the parking garage is located and the standards you follow, the consensus is that maintaining air quality while satisfying safety requirements is a key challenge for HVAC designers specializing in car park ventilation.90003 90023 How Can CFD Help? 90024 90002 Finding the optimal location, number, and configuration of the exhaust fans required for garage ventilation, while ensuring that it meets the tenability requirements of CO exposure limit set by health and safety regulations, can be a challenging task. Computational fluid dynamics (CFD) can simultaneously predict airflow, heat transfer and contaminant transport inside the parking garage, guiding the engineer towards the right design decision. 90003 90143 90002 90029 To learn how to apply cloud-based CFD to test and optimize garage ventilation for the removal of carbon monoxide and other pollutants, watch the recording of this webinar: 90030 90003 90009 Case Study: Reducing CO Concentration Levels in a Garage with Jet Fan Placement 90010 90002 Although natural ventilation may be sufficient for open and semi-open parking lots, channeled mechanical or jet fan ventilation systems should be used in underground and closed parking garages in order to prevent excessive CO concentration levels.The jet fan ventilation system is one of the most widely used ventilation systems for carbon monoxide extraction in underground car parks. The aim of this study is to undertake CFD modeling of a car park to simulate how the correct placement of a jet fan can help to reduce CO concentrations without the need for a complex duct system. 90003 90002 For this case study, we will use a project from the SimScale Simulations Library-copy it for free and use it for your own analysis: Pollutant Extraction from a Parking Garage.The aim of this project is to evaluate ventilation performance in an underground car parking garage and to verify that the jet fan ventilation system causes a sufficient reduction in CO concentration levels. 90003 90002 Two garage ventilation system configurations are simulated: 90003 90013 90014 Without jet fans (only supply and exhaust fans opening) 90015 90014 With jet fans 90015 90018 90162 Underground Garage Ventilation System 90002 CFD simulations are performed to examine velocity and CO concentration distribution for the two scenarios using the simulation parameters below.3) 90194 90031 90028 90193 23642 90194 90031 90036 90027 90028 90193 Total number of vehicles parked 90194 90031 90028 90193 200 90194 90031 90036 90027 90028 90193% of moving cars (entering / exiting the garage in peak hours — worst case scenario) 90194 90031 90028 90193 40 90194 90031 90036 90027 90028 90193 Total number of moving cars 90194 90031 90028 90193 80 90194 90031 90036 90027 90028 90193 CO emission rate per vehicle (mg / s) 90194 90031 90028 90193 8.3-s) 90194 90031 90028 90193 2.77E-08 90194 90031 90036 90133 90134 90253 CFD Simulation Results 90254 90255 CO Concentration in PPM at 1.8m Height 90002 The simulation results visualize the CO concentration patterns for both garage ventilation system designs, clearly revealing several large «dead zones» in the first configuration without jet fans. The post-processing images below further highlight the regions with CO concentration over 60 PPM in the first design, which have been eliminated with the help of jet fan placement.90003 90258 Regions with CO Concentration> 60 PPM 90259 Velocity Contours at the Jet Fans ‘Height 90002 90261 90003 90002 To put these results into numbers, incorporating jet fans into the garage ventilation system can lower the maximum CO concentration by 55,1%! That is in addition to improving air velocity and the overall air quality throughout the garage space. 90003 90009 Conclusions 90010 90002 90268 90003 90002 The above case was just a simple example of how cloud-based CFD simulation can help HVAC design engineers easily test any design change without leaving the web browser.The simulation took only five hours of manual time and eight hours of computing time, allowing us to virtually investigate the performance of a garage ventilation system and ensure the adequate movement of air. 90003 90002 Until recently, only engineers with vast expertise in numerical analysis and a large budget could fully benefit from CFD simulation tools. With the emergence of flexible cloud-based solutions, however, it has become an industry standard.
