Composition of air conditioning refrigeration system for electric vehicle
Electric vehicle air-conditioning refrigeration system mainly by: electric compressor, electric compressor controller, condenser, pipe system (liquid tube, compressor exhaust pipe, compressor suction pipe, indoor temperature sensors, outdoor temperature sensors, solar sensors, air-conditioning host (evaporator, heater, temperature damper actuator, Mode damper actuator, internal and external circulation damper, blower, evaporator temperature sensor), expansion valve, air-conditioning controller components.
Control principle of air conditioning refrigeration system for electric vehicle
The principle of the electric air conditioning refrigeration system is: After the user starts the automobile air conditioning system according to the operating procedure, the whole vehicle controller sends out the instruction through the compressor controller to drive the electric compressor, drives the refrigerant to circulate in the air conditioning system. The compressor compresses the gaseous refrigerant into the refrigerant gas of high temperature and pressure, and through the compressor exhaust pipe to the condenser, the refrigerant in the condenser for cooling, cooling, after condensation becomes the medium temperature high pressure liquid refrigerant, the medium temperature high pressure liquid refrigerant through the liquid tube arrives expands the valve to release becomes the low-temperature low pressure liquid refrigerant, the low-temperature low pressure liquid refrigerant immediately enters the evaporator, absorbs the air heat which flows through the evaporator in the evaporator, causes the ambient air temperature to reduce, The blower will blow the air around the evaporator to produce refrigeration effect.
