OEM Customized Adjustable Air Pressure Switch - Automobile Air Conditioning Pressure Switch – Anxin Detail:

The automobile air conditioner pressure switch is a part to protect the air conditioner refrigeration, it can adjust the pressure in time.When the refrigerant pressure in the air conditioning system is too high or too low, the pressure switch is turned off, so that the compressor does not work (the pressure switch and other switches control the relay to control the compressor) and protect the system components from damage.Generally divided into two-state pressure switch and three-state pressure switch. The pressure switch is generally connected to the compressor, the condenser electric fan or the water tank fan. It is controlled by the ECU on the car and controls the opening of the fan according to the pressure change in the air conditioner. Turn off, or the air volume, when the pressure is too high, the compressor will stop working to protect the system.

All pressure parameters of our company’s products are customized according to customer requirements to better match the equipment. If you don’t know what kind of start-stop pressure your equipment needs, please contact us. We have professional engineers to measure it and customize the appropriate parameters for you .

Automobile air conditioners are probably composed of compressors, condensers, receiver dryers, expansion valves, evaporators and blowers.Generally, there are four stages of compression process, heat dissipation process, throttling process, and heat absorption process.The compression process is that the compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, and the compressed high-temperature and high-pressure gas enters the condenser. After the condensed gas, it becomes a liquid and discharges a large amount of heat.The refrigerant liquid with higher temperature and pressure is turned into low-temperature misty droplets through the expansion valve device. Finally, the mist refrigerant enters the evaporator and absorbs a large amount of heat in the process of evaporating into a gas.When the car air conditioner is in use, when there are abnormal conditions such as blockage of the cooling fins, non-rotating cooling fans, or excessive refrigerant, the system pressure will be too high. If it is not controlled, the high pressure will damage the system components.
