Abstract

The invention discloses a heat pump air-conditioning system with a waste heat recovery function. The system comprises an oil liquid circulation module, an engine cooling module, an evaporator and a compressor, the oil liquid circulation module is communicated with the engine cooling module, the engine cooling module is arranged on one side of the evaporator, an expansion valve is arranged on a pipeline between the evaporator and an indoor condenser and an outdoor condenser, a gas-liquid separator is arranged on a pipeline between the evaporator and the compressor, the compressor is communicated with the indoor condenser and the outdoor condenser separately, and a blower is further arranged on one side of the indoor condenser. The heat pump air-conditioning system with the waste heat recovery function is simple in structure principle, heating can be effectively conducted by adopting waste heat of automobile exhaust gas, the heat supplying capability of a heat pump is improved, and the energy is saved.

Description

technical field [0001] The invention relates to the field of heat pump air conditioning systems, in particular to a heat pump air conditioning system with waste heat recovery function. Background technique [0002] With the rising popularity of new energy powered vehicles, air conditioning has actually become one of the major bottlenecks in the practicality and marketization of new energy powered vehicles. The use of electricity for cooling and heating alone will make electric vehicles and fuel cell vehicles drivable. The mileage is reduced by at least 50%, so that even the traditional typical urban traffic is difficult to cope with. At the same time, in terms of high efficiency and environmental protection, some electric vehicles and hybrid vehicles use as little fuel as possible to meet power requirements. For example, some hybrid vehicles convert excess mechanical energy into electrical energy to charge the battery in engine mode. Then switch to electric mode for electri...
