Abstract

The invention relates to a temperature compensating device of a heat pump air-conditioner, which resolves the problem that an existing heat pump air conditioner does not have a temperature compensating function, and when the exhaust temperature of a compressor is over high, the compressor can be damaged. The technical scheme includes that the temperature compensating device comprises a compressor, an exhaust tube of the compressor is connected with a refrigerant inlet of an automobile outer unit assembly via a condenser core, a liquid storage dryer and a valve portion of an expansion valve, a refrigerant outlet of the automobile outer unit assembly is connected with an air return pipe of the compressor via a temperature sensing portion of the expansion valve, a temperature sensor is mounted on the exhaust pipe of the compressor, an outlet of the liquid storage dryer is further connected with the air return pipe of the compressor via an electromagnetic stop valve, an output end of the temperature sensor is connected with an input end of a microprocessor, and an output end of the microprocessor is connected with electromagnetic valve stop valve. The temperature compensating device of the heat pump air-conditioner is simple in structure, and can prevent over high exhaust temperature of the compressor from damaging the compressor, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to a temperature compensation device for a heat pump air conditioner. Background technique [0002] A large part of the failures of existing heat pump air-conditioning systems are compressor burnout and leakage, aging, cracking and leakage of the rubber parts of the compressor exhaust pipe. Most of these problems are caused by the high discharge temperature of the compressor. Usually, when the exhaust gas temperature is too high, the only way to reduce the temperature is to repeatedly start and stop the compressor or reduce the speed, which will easily damage the compressor and reduce the comfort of use. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a heat pump air conditioner temperature compensation device with simple structure, which can prevent the compressor from being damaged due to excessive discharge temperature of the compressor and...
