Logistical cold storage,also known as cold storage, is a warehouse which use cooling facilities to create suitable humidity and low temperature and processing and storage of agricultural and livestock products.
Cold room is made up of cooling room(about 0°C),freezing room(-23~-30ºC),refrigeration room(-12~-20ºC),ice storage room(-4~-10ºC).Plain layout of cold storage should be reasonable,as far as possible to reduce the envelope area.Cold storage should be clearly distinguished between high and low temperature to minimize the area of the maintenance structure taking into consideration the convenience of expansion and maintenance. Multi-layer cold storage is often built dumbbell style or single style. Dumbbell style divides high temperature and low temperature storage into two separate maintenance structures. Single style separates the floor from the ground with heat insulation walls between high temperature and low temperature storage. The door is equipped with air curtain to prevent cold air from overflowing. Low thermal conductivity materials is laid on the wall,celling and ground to prevent external heat from flowing into storage. There is need to be laid material that is resistant to permeation in the heat insulation layer to prevent outdoor water vapor permeating.
