Embodiment Construction

[0053] The present invention will be described in further detail below through specific examples.

[0054] An electric air conditioning system for electric vehicles, such as figure 1 As shown, it includes a compressor 1, a four-way valve 2, an external heat exchanger 3, a two-way expansion valve 4, an internal heat exchanger 5, and a gas-liquid separator 7. The external heat exchanger 3 and the internal heat exchanger The heater 5 is equipped with an outside fan 9 and an inside fan 8 respectively. The four-way valve 2 is provided with an air inlet 21, an air return port 23, a cooling flow port 24 and a heating flow port 22. The compressor 1 The exhaust port of the four-way valve 2 communicates with the air inlet 21 of the four-way valve 2, and the air return port 23 of the four-way valve 2 is connected with the air suction port of the compressor 1 through the air return pipeline, and the gas-liquid separator 7 is arranged in the return air On the gas pipeline, the external he...

Abstract

The invention discloses an electric air conditioning system of an electric automobile. The electric air conditioning system comprises a compressor, a four-way valve, an exterior heat exchanger, a two-way expansion valve, an internal heat exchanger and a gas-liquid separator, wherein gas distributors are respectively arranged at the gas connecting ends of the exterior heat exchanger and the internal heat exchanger; the gas distributor of the exterior heat exchanger is connected with a refrigeration flow opening of the four-way valve; the gas distributor of the internal heat exchanger is connected with a heating flow opening of the four-way valve; liquid distributors are respectively arranged at the liquid connecting ends of the exterior heat exchanger and the internal heat exchanger; the liquid distributor of the exterior heat exchanger is connected with a port of the two-way expansion valve; the other port of the two-way expansion valve is connected with the liquid distributor of the exterior heat exchanger. According to the electric air conditioning system disclosed by the invention, not only can refrigeration and heating be realized on the electric automobile, but also the heat exchange efficiency can be improved, and the refrigeration and heating effect of the electric air conditioning system is improved. In addition, the invention also discloses a control method to realize the intelligent operation of the electric air conditioning system.

Description

technical field [0001] The invention relates to an electric air-conditioning system of an electric vehicle, which is used in a pure electric vehicle, and also relates to a control method of the electric air-conditioning system. Background technique [0002] In recent years, pure electric vehicles have become more and more popular. The driving of the vehicle is completed by the main drive motor, and the main drive motor is powered by the battery pack. As an electric air-conditioning system applied to pure electric vehicles, it needs to consume the battery pack in actual use. Therefore, the electric air conditioning system of a pure electric vehicle will affect the cruising range of the vehicle. So how to make the electric air-conditioning system of pure electric vehicles more energy-saving, and the energy utilization rate and conversion rate are higher is the difficult problem on the electric air-conditioning system of pure electric vehicles at present. In addition, whether ...
