Electric pan refrigerator door [Preferred] Shandong Huayu more generally cold refrigerator cooling by using low temperature gasification of liquid (ammonia or freon) as a coolant refrigerator door fittings, evaporated under low pressure conditions and mechanical control absorb heat storage compartment electric refrigerator door, 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 evaporative cooling pipe installed in the refrigerated warehouse, liquid coolant passes through the throttle refrigerator door, directly absorb heat and cool inside the warehouse. Indirect cooling air from the blower into the coffers of the suction air cooling device, after hovering in the air is the evaporation tube heat absorption cooling device inside the refrigerator door, Shandong, 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. Shandong Huayu cold [Preferred] (a) divided by the size of cold storage capacity of cold storage capacity has not unified division, generally divided into large, medium and small. Large cold storage refrigeration capacity 10000t above; medium-sized refrigerated cold storage capacity in 1000 ~ 10000t; small refrigerator refrigerated capacity 1000t below. (B) the design temperature refrigeration sub-divided into high, medium temperature, low temperature and cryogenic refrigerator four categories. ① general design of high-temperature refrigerated cold temperatures at -2 ℃ to + 8 ℃; ② temperature refrigerated cold storage design temperature at -10 ℃ to -23 ℃; ③ low temperature, the temperature is generally -23 ℃ to -30 ℃; ④ ultra Low temperature is generally frozen bank -30 ℃ to -80 ℃.
