A four-way valve is arranged in the heating process to enable the flow direction of Freon in the condenser and the evaporator to be opposite to that in the cooling process.
However, the compressor is a high-energy-consumption device, the power of the compressor is generally more than 3Kw, the fuel consumption of the compressor of the fuel vehicle can be increased, the power consumption of the compressor of the new energy vehicle can be increased, and the endurance mileage of the vehicle is shortened. On the other hand, the cost of the compressor is relatively high, and the compressor needs to work normally, and a radiator, an evaporator, a high-pressure pipe, a low-pressure pipe, an expansion valve and other devices are matched with the compressor, so that the system is complex and the cost is too high.
