The process of penetration of outside air into cold storage does not lose the cold of a room, but

No gas in low temperature cold storage. When circulating through a cooling coil, the water is condensed back. So the distribution of water vapor pressure in the air chamber smaller these cookie jars than outside. these cookie jars So water vapor tends to permeate these cookie jars the room through the wall insulation.
For the warehouse building, the moisture can penetrate wet insulation reduces the thermal insulation properties of the material. So when building warehouses need to be scanned and tar layer waterproof tar paper liner. Waterproof tar paper liners need 2 layers, the layers overlap each other up and taped closed, continuous membrane Cuisine on the entire area of the warehouse.
For the warehouse made of insulation for outside and inside the warehouse religion class should not have the ability to reach moisture. However, to avoid sharp objects puncturing the insulation leads to wet insulation. these cookie jars So in cold storage, people often make the pallet wood to avoid scratching the floor when pushing the car, pointed objects in the cargo.
Between these cookie jars the insulation after assembly should have small openings sealed with silicone sealant. Outside the cold store, we also bury the wire at 0.8 m column to avoid damage to the shell shock warehouse.
Cold storage preservation of long days, cold air passing through the ground insulation. When the temperature is low, iced water, this process makes the long-term accumulation of the larger stones leading to edematous, destroying the structure of the building insulation.
Installation of cold storage on the eel or the stent system. The eel ventilation poured concrete or brick high cards about 100 mm - 200 mm. Surface eel on 2 sides 2% slope to avoid water stagnation.
This method is simple, easy to install but high operating costs. Currently little use.
For background warehouse building, to avoid freezing the background. Economic measures is the use of background ventilation tubes. The vent pipe is 100 mm diameter PVC pipe layout spacing these cookie jars 1.000 mm - 1.500 mm, go zigzag background, information on air the first two. In the process of working on the wind through pipes, heat exchangers and heating to the ground floor, these cookie jars to prevent freezing.
When shipping or inspection opening operation, outside air will penetrate into the warehouse causing heat loss and significantly affect the maintenance mode.
Wind hot outside in cold storage moves from the top down and the wind chill in the room rushed out from under the base of the insulation panels.
The process of penetration of outside air into cold storage does not lose the cold of a room, but also bring moisture into the room and then accumulate on the indoor these cookie jars unit affects the working efficiency of the system.
When a large cold storage, we built a padded room to avoid outside these cookie jars air into the cold room.
Use plastic monitor assembled from many small pieces. The plastic plate has good cold tolerance and high durability, the lid is folded up at least another 1 about 50 mm while ensuring convenience for travel and when it has no place in a closed curtain. these cookie jars
Field of heat transfer from high temperature environment in low temperature environments through wall insulation.
The airflow
