The invention is suitable for the technical field of automobile air conditioners, and particularly relates to a direct type heat pump automobile air conditioning system capable of recycling waste heat in a stepped mode. Comprising an in-vehicle refrigeration mode, an in-vehicle refrigeration and battery cooling mode, a battery independent cooling mode, a heat pump in-vehicle heating mode, a PTC (Positive Temperature Coefficient) heat compensation mode, a motor heat dissipation mode, a waste heat utilization mode, a defrosting mode and other modes, a linked battery heat management function can be realized, and battery preheating and in-vehicle heating can be carried out while defrosting is carried out; the thermal comfort in the vehicle is improved; and the battery is ensured to work in a working temperature range. And in addition, motor waste heat is used as a low-temperature heat source for heating in the automobile under the low-temperature condition, and the problems that when a heat pump type automobile air conditioner operates under the low-temperature working condition, the exhaust temperature of a compressor is too high, and the heating capacity is obviously insufficient are solved. And dehumidification can be carried out while refrigeration is carried out, and the heat comfort in the automobile is improved.

    本发明适用于汽车空调技术领域,特别涉及一种余热梯级回收的直接式热泵汽车空调系统,本系统具有多种工作模式,包括车内制冷模式、车内制冷同时电池冷却模式、电池单独冷却模式、热泵车内制热模式、PTC补热模式、电机散热模式、余热利用模式、除霜模式等多种模式于一体,能够实现联动的电池热管理功能,并且能够在除霜的同时进行电池预热和车内加热,提高车内热舒适性并且保证电池在工作温度范围内工作。而且在低温情况下通过利用电机余热作为低温热源进行车内采暖,解决热泵式汽车空调低温工况运行时,压缩机的排气温度过高,制热量明显不足等问题。并可以在制冷同时进行除湿,提升车内热舒适性。
