The present invention relates to a turbine generator applied to a heat pump cooling and heating system for an electric vehicle including a heat pump capable of realizing a cooling cycle by circulating a refrigerant in the order of a condenser, an expansion valve, an evaporator, and a compressor, and at the same time realizing a heating cycle through a 4-way valve. The turbine generator includes: a turbine connected between the expansion valve and the evaporator so that the refrigerant passing through the expansion valve flows into a high-pressure port and is discharged through a low-pressure port; and a generator which produces electricity by rotation driving of the turbine. Accordingly, the turbine is connected to a capillary constituting the expansion valve, and a refrigerant gas passing through the capillary tube rotates the turbine to drive the turbine so as to generate electricity by operating the generator, such that energy consumed by the expansion valve can be regenerated and used in charging a battery of the electric vehicle.

    본 발명은 냉매가 응축기, 팽창밸브, 증발기, 압축기의 순서로 순환하여 냉방사이클이 구현 가능함과 동시에, 4방향밸브를 통해 난방사이클로도 구현 가능한 히트펌프를 포함하는 전기 자동차용 히트펌프 냉난방 시스템에 적용되는 터빈 발전기에 관한 것으로서, 상기 팽창밸브와 상기 증발기 사이에 연결되어, 상기 팽창밸브를 통과하는 냉매가 고압측 포트로 유입되어 저압측 포트로 배출되도록 함으로써 회전 구동되는 터빈과; 상기 터빈의 회전 구동에 의해 전기를 생산하는 발전기를 포함하는 것을 특징으로 한다. 이에 따라, 팽창밸브를 구성하는 모세관에 터빈을 연결하여 상기 모세관을 통과하는 냉매가스로 터빈을 회전 구동하여 이로부터 발전기를 돌려 전기를 생산함으로써 상기 팽창밸브에서 소모되는 에너지를 재생하여 전기 자동차의 배터리에 충전하여 사용하게 할 수 있다.
