家用冰箱压缩机的冷却,通常是由它的外壳与周围空气的对流换热来进行的。从蒸发器吸出的制冷剂蒸汽用来冷却电动机。在周围空气温度高于正常温度的条件下(包括热带条件),以及在起动和应急状态下,随着热负荷的增加,压缩机运转会导致烧毁电机绕组。这是由于在油和氟利昂中绝缘层的物理化学特性恶化所致。因为在加热时油可能被分解,形成腐蚀导线绝缘的脂肪酸。压缩机的电机绕组设计的正常工作温度不高于130℃,而在上述情况下可能发热达200～ Domestic refrigerator compressor cooling, usually by its shell and the surrounding air convection heat transfer to. The refrigerant vapor drawn from the evaporator is used to cool the motor. With ambient air temperatures above normal (including tropical conditions), as well as during start-up and emergency conditions, as the heat load increases, compressor operation can result in burning of the motor windings. This is due to the deterioration of the physicochemical properties of the insulating layer in the oil and freon. Because the oil may be decomposed when heated to form a fatty acid that will corrode the wire insulation. Compressor motor winding design of the normal operating temperature is not higher than 130 ℃, while in the above case may heat up to 200 ~
