一、冰箱的冰阻的现象冰箱在运转几分钟或十几分钟时,电机和制冷效率均属正常,但突然蒸发器温度骤然上升,里边结的霜开始溶化.也无制冷剂的流动声,低压突然下降,高压在冰阻时升高,而后慢慢下降到~*t_k 的范围(一般高于~*t_k 值),这时冷凝器不放热。如果是“一星极”冰箱高压压力不下降,反而上升,重者电机进行电流保护,
First, the phenomenon of ice resistance of the refrigerator When the refrigerator is running for a few minutes or more than ten minutes, the motor and cooling efficiency are normal, but suddenly the temperature of the evaporator rises suddenly, the frost in the inside of the refrigerator begins to melt, and there is no flow of refrigerant. The low pressure suddenly drops, the high pressure rises during ice resistance, and then slowly falls to the range of ~*t_k (usually higher than ~*t_k), when the condenser does not release heat. If it is a “one-pole-pole” refrigerator, the high pressure does not drop, but rises, and the motor is protected by current.
