民德VEB MAB Schkenditz厂提出了一种制冷机蒸发器融霜装置。如图所示,制冷机由带电动机2的压缩机1、带风机4的冷凝器3、热力膨胀阀5和带风机7的蒸发器6组成。当待冷却库房中达到最低给定温度时,温控器10停下风机,开启电磁阀8,于是压缩机1排出的热气经管路9进入蒸发器6,其融霜过程开始。融霜结束的信号由装于蒸发器6出口的温度传感器11发出,并使电动机2停
Midea VEB MAB Schkenditz plant proposed a refrigerator evaporator defrosting device. As shown in the figure, the refrigerator is composed of a compressor 1 with a motor 2, a condenser 3 with a fan 4, a thermal expansion valve 5 and an evaporator 6 with a fan 7. When the minimum temperature to be cooled in the warehouse is reached, the thermostat 10 stops the fan and opens the solenoid valve 8, so that the hot air discharged by the compressor 1 enters the evaporator 6 through the pipe 9, and the defrosting process starts. The defrosting signal is sent from the temperature sensor 11 installed at the outlet of the evaporator 6, and the motor 2 stops
