Electric pan refrigerator door [Preferred] Shandong Huayu more generally cold refrigerator cooling by using low temperature gasification of liquid (ammonia or freon) electric refrigerator door as a coolant to evaporate under the conditions of low pressure and mechanical control flat open refrigerator door, absorbing 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.
