Abstract

The invention discloses a pure electric vehicle battery constant temperature and air conditioning system machine. The system comprises a four-way valve, an external heat exchanger, a first two-way expansion valve, an internal heat exchanger, a gas-liquid separator, a water tank, a battery box, a refrigeration coil, a water pump and a temperature regulating coil. The water pump is connected with awater outlet of the water and a temperature regulating coil. The other end of the temperature regulating coil is connected to the water return port of the water tank, A refrigeration coil is arrangedin the water tank, the exhaust port of the compressor is communicated with the four-way valve, A four-way valve is used to connected to the air inlet, the air suction opening of the compressor, the external heat exchanger and the internal heat exchanger; and the refrigerant coil is also connected in the refrigerant circulation system. Four control valves are used to control and regulate the operation route of the refrigerant, so as to realize the temperature regulation of the pure battery, the operation of the pure air conditioner and the simultaneous operation of the battery and the air conditioner. The battery constant temperature and air conditioning system can regulate the temperature of the battery pack in the battery box so that the battery can operate in an ideal temperature environment, and the refrigeration and heating requirements of the motor car can be met.

Description

technical field [0001] The invention relates to a pure electric vehicle battery constant temperature and 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 use more energy-saving, and the utilization rate and conversion rate of energy are higher is the difficult problem on the electric air-conditioning system of pure electric vehicles at present. In addition, whether the control method of the electric air-conditioning system is reasonable or not directly af...
