Vehicle and air conditioner system thereof

Abstract

The invention discloses a vehicle and an air conditioner system thereof. The air conditioner system comprises a refrigerant circulating system and a cooling liquid circulating system, wherein the refrigerant circulating system comprises a compressor, a four-way valve, an indoor heat exchanger and an outdoor heat exchanger; the outdoor heat exchanger comprises a first heat exchange channel and a second heat exchange channel; the four-way valve is separately connected with the compressor, the indoor heat exchanger and the first heat exchange channel of the outdoor heat exchanger; the cooling liquid circulating system comprises a motor, a heat sink and an outdoor heat exchanger; and the heat sink is separately connected with the motor and the second heat exchange channel of the outdoor heat exchanger in parallel so that cooling liquid in the heat sink selectively flows to the motor and the second heat exchange channel. By the outdoor heat exchanger of the air conditioner system, the heat dissipation area can be increased in a disguised manner, and the endurance mileage of the vehicle can be lengthened.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle air conditioning system and a vehicle with the air conditioning system. Background technique [0002] With the shortage of fossil fuels and the increasingly serious environmental problems, new energy vehicles have developed along with the trend, and their market share has increased year by year, but the speed of development is still relatively slow. For electric vehicles, low mileage is the bottleneck that limits their development. How to improve the utilization efficiency of battery power or increase battery capacity is an effective measure to solve this problem. [0003] At present, electric heating devices are generally used for heating electric vehicles, but the thermal efficiency of the electric heating system is low, and the maximum heating COP (air conditioning energy efficiency ratio) is 1. When heating at low temperature, the cruising range of the car will dro...

For electric vehicles, the low mileage is the bottleneck that limits their development. How to improve the utilization efficiency of battery power or increase battery capacity is an effective measure to solve this problem

[0003] At present, electric heating devices are generally used for heating electric vehicles, but the thermal efficiency of the electric heating system is low, and the maximum heating COP (air conditioning energy efficiency ratio) is 1. When heating at low temperature, the cruising range of the car will drop by more than 20%, which seriously limits the cruising range of the car. mileage
