The invention provides a waste heat recovery automobile air conditioning system and a control method, the automobile air conditioning system comprises an expansion machine, a compressor, an engine, an external heat exchanger, an internal heat exchanger, a throttling device and a heat recovery heat exchanger, and the heat recovery heat exchanger exchanges heat with the engine to recover heat of the engine. The inlet end of the expansion machine can be connected with the heat recovery heat exchanger so that a working medium heated by the heat recovery heat exchanger can be introduced into the expansion machine to do work, the expansion machine is connected with the compressor through a clutch so that the compressor can be driven to operate through the expansion machine, and the compressor, the vehicle exterior heat exchanger, the throttling device and the vehicle interior heat exchanger can form a refrigeration cycle system. In the refrigeration cycle system, the same working medium as the working medium entering the expansion machine is adopted as a refrigerant, and the outlet end of the expansion machine can be communicated to the outlet end of the compressor. According to the invention, the problem of low cruising ability of the automobile caused by low air conditioning efficiency of the existing automobile air conditioning system can be solved.

    本发明提供一种余热回收的汽车空调系统和控制方法,汽车空调系统,其包括:膨胀机、压缩机、发动机、车外换热器、车内换热器、节流装置和热回收换热器,热回收换热器与发动机换热以能回收发动机的热量,膨胀机的入口端能与热回收换热器连接,以能引入经过热回收换热器被加热后的工质进入膨胀机中做功,膨胀机与压缩机通过离合器连接,以能通过膨胀机驱动压缩机运行,压缩机、车外换热器、节流装置和车内换热器能组成制冷循环系统,制冷循环系统中采用与进入膨胀机中相同的工质作为制冷剂,膨胀机的出口端能连通至压缩机的出口端。根据本发明能解决现有的汽车空调系统空调效率低,导致汽车续航能力低的问题。
