[0002] With the rapid development of society, the awareness of energy saving and environmental protection and the enhancement of product demand, it is an energy-saving, environmentally friendly, high-safety, and multi-functional unit for heat pump hot water air conditioners, especially through the reversing of five-way heat pump hot water air conditioners. In the system where the valve is used as a refrigerant operating mode conversion, currently only the throttling device combined with a check valve and a capillary tube or an expansion valve is used for throttling. The working condition adjustment is in the best state, there is no thermal expansion valve that can automatically adjust the working condition like the thermal expansion valve

The invention discloses a three-way thermostatic expansion valve applicable to a heat pump hot water air conditioning unit, which is characterized in that the valve is provided with three connecting ports connected with a heat exchanger; a connecting port 1 and a connecting port 2 can be respectively connected with an outdoor machine heat exchanger and an indoor machine heat exchanger randomly; a connecting port 3 is a connecting port with a hot water box heat exchanger; a reverse unidirectional valve core is arranged between the connecting port 1 and a valve chamber 1; a reverse unidirectional valve core is arranged between the connecting port 2 and the valve chamber 1; the connecting port 1 is connected with a valve core 2 through a channel 1 which is internally provided with a forward unidirectional valve core; the connecting port 2 is connected with the valve chamber 2 through a channel 2 which is internally provided with a forward unidirectional valve core; and the valve can implement four kinds of throttling control modes. The technology solves the problem that the heat pump hot water air-conditioning throttling is difficult to solve by the existing unidirectional thermostatic expansion valve and the bidirectional thermostatic expansion valve.
Description
technical field [0001] The invention relates to the application of heat pump hot water air conditioning technology, in particular to a throttling fitting applied to a heat pump hot water air conditioner unit. Background technique [0002] With the rapid development of society, the awareness of energy saving and environmental protection and the enhancement of product demand, it is an energy-saving, environmentally friendly, high-safety, and multi-functional unit for heat pump hot water air conditioners, especially through the reversing of five-way heat pump hot water air conditioners. In the system where the valve is used as a refrigerant operating mode conversion, currently only the throttling device combined with a check valve and a capillary tube or an expansion valve is used for throttling. The working condition adjustment is in the best state. There is no thermal expansion valve that can automatically adjust the working condition like the thermal expansion valve. Conte...
