Manually pan refrigerator door [Preferred] Shandong Huayu main purpose cold folding Edit this paragraph [2] is a method of artificial refrigeration [1] makes fixed space reaches a predetermined temperature to facilitate storage of building materials. Cold can be widely used in food plants, dairy, pharmaceutical, chemical plants, fruit and vegetable warehouse, eggs warehouses, hotels, restaurants, supermarkets, hospitals, blood banks, the armed forces, the test room. Cold storage is mainly used for food, dairy products, meat, fish, poultry, fruits and vegetables, drinks, flowers, plants, tea, medicine, chemicals, electronic instrumentation, such as thermostats storage. [1] Product Category folding edit this section (1) according to the structure in the form of points, the cold can be divided into: a combination of civil cold cold (cold events) (2) by using the properties of sub-Color cold storage doors, cold storage can be divided into: the production of cold Retail distribution of cold cold storage (3) refrigeration capacity divided by cold refrigerator door installation, cold storage can be divided into: large cold: these cold cold cold storage capacity of the medium in 10000t above: These cold storage refrigeration capacity in the range of 1000 ~ 10000t small refrigerator (small refrigerator): These cold below freezing capacity 1000t (4) by cold temperatures, cold can be divided into: high-temperature cold: these cold cold temperature -2 ℃ ~ 8 ℃ temperature cold: these cold cold temperature -10 ℃ ~ -23 ℃ cold storage: These cold cold temperature -23 ℃ ~ -30 ℃ ultra-low temperature cold: these cold cold temperature below -30 ℃. Electric pan refrigerator door [Preferred] Shandong Huayu more generally cold cold garage door by cooling mechanism, the use of low temperature gasification of liquid (ammonia or freon) as a coolant refrigerator door material to conditions in low and mechanical control evaporated, to absorb heat storage compartment so as to achieve the purpose of cooling down. The most commonly used is a compression type refrigeration machine, is mainly composed of a compressor, a condenser, throttle valve and evaporator tubes and other components. Evaporation tube apparatus according to the way they can be divided into two kinds of direct and indirect cooling. Direct cooling evaporator tube mounted within refrigerated warehouse, the liquid coolant passes through the throttle valve, the direct absorption of heat within the warehouse and cooling. Indirect cooling air from the blower into the coffers of the suction air cooling device, after hovering in the air is cooling device endothermic evaporation tube, sending internal storage and cooling. Advantages air cooling method is cooling rapidly, more uniform inside temperature, carbon dioxide and other harmful gases generated during storage at the same time be able to bring out outside the library.
