What are the common parts of the car heating and cooling system?
- Automotive air conditioning and refrigeration system is mainly composed of compressor, expansion valve, condenser, evaporator and blower, etc., during which the various components between the use of high-pressure rubber pipe and steel pipe connected into a closed system, in the refrigeration system work, the refrigerant will In a different state in this space circulation, and this cycle is divided into four processes: 1, the compression process: the compressor inhalation of the evaporator at the exit of the low temperature and low pressure refrigerant gas, it is compressed into high temperature and high pressure gas Discharge the compressor. 2, the heat process: high temperature and high pressure superheated refrigerant gas into the condenser, due to the pressure and temperature reduction, the refrigerant gas condensed into liquid, and discharge a lot of heat. 3, the throttle process: the temperature and pressure of the refrigerant through the expansion of the device after the expansion of large volume, pressure and temperature of the sharp arrest Cao Ken 丨 old investigation of intestinal fried to decline in the mist (small droplets) discharge expansion device The 4, endothermic process: mist refrigerant liquid into the evaporator, so the refrigerant boiling point is much lower than the evaporator temperature, so the refrigerant liquid evaporated into gas. In the evaporation process a large number of absorption of heat around, and then low-temperature low-pressure refrigerant vapor into the compressor. The above process is repeated for the purpose of reducing the temperature of the air around the evaporator. Automotive air conditioning refrigeration and home air conditioning refrigeration is exactly the same, the need for compressor work, and heating is much simpler, because the car engine after cooling there are about 90 degrees, directly facing the engine blowing is hot air friends.s
