Embodiment 1

[0065] This application provides an economical electric vehicle air conditioning system, such as image 3 As shown, it includes an air conditioner controller 13, a compressor 1, a first cut-off valve 21, a second cut-off valve 22, a third cut-off valve 23, a fourth cut-off valve 24, a fifth cut-off valve 25, and a sixth cut-off valve. Switch cut-off valve 26, outdoor heat exchanger 5, first cut-off thermal expansion valve 7, second cut-off thermal expansion valve 10, indoor heat exchanger 8 and gas-liquid separator 15; also includes fan 6, blower 9, including The temperature sensor 11 of the indoor heat exchanger, the pressure sensor 12 and the outdoor temperature sensor 14 are all connected to the air conditioner controller with electrical signals.

[0066] Both the blower and the fan are electrically connected to the air conditioner controller.

[0067] Among them, the indoor heat exchange temperature sensor is set at the indoor heat exchanger to detect the temperature sign...

Embodiment 2

[0104] An economical electric vehicle air conditioning system, such as Figure 7 As shown, it includes an air conditioner controller 107, a compressor 101, a first two-position three-way valve 111, a second two-position three-way valve 102, a two-way thermal expansion valve 106, an outdoor heat exchanger 103, an indoor heat exchanger 108 and air The liquid separator 112 includes an indoor heat exchanger temperature sensor 110, a pressure sensor 113 and the outdoor temperature sensor 104, all of which are electrically connected to the air conditioner controller.

[0105] In this embodiment, two-way thermal expansion valves are used to replace two shut-off thermal expansion valves and two on-off shut-off valves, and two two-position three-way valves are used to replace four on-off shut-off valves, so that the system is more concise and the cost is lower.

[0106] A blower 109 and a fan 105 are included, and both the blower and the fan are electrically connected to the air condit...

Abstract

The invention relates to an economical electric car air conditioner system and a control method. The system comprises an air conditioner controller, a compressor, a first on-off stop valve, a second on-off stop valve, a third on-off stop valve, a fourth on-off stop valve, a fifth on-off stop valve, a sixth on-off stop valve, an outdoor heat exchanger, a first stop type heating power expansion valve, a second stop type heating power expansion valve, an indoor heat exchanger and a gas and liquid separator. According to the technical scheme, by adopting the on-off stop valves, a refrigerant conversion structure is simple, the reliability is high, four-way conversion and electric heating glass is adopted, the comprehensive air conditioner system solution is obtained, and system heating and defrosting energy dissipation is lowered.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle air conditioning systems, in particular to an economical electric vehicle air conditioning system and a control method. Background technique [0002] Electric vehicles generally use electric heaters for auxiliary heating in winter due to lack of engine waste heat, but the heating efficiency of electric heaters is low, which seriously affects the cruising range of electric vehicles. Heat pump air conditioners have good cooling and heating performance and are the best alternative to electric heating assisted air conditioning systems. However, there are still many difficulties to be solved in the application of heat pump air conditioning system to electric vehicles. First, the operating efficiency of the heat pump air-conditioning system is low in low-temperature conditions, and the heating performance needs to be improved; second, the tube-fin heat exchanger commonly used in household heat...
