Structure of truck air conditioner 2022-08-25
 
Truck air conditioners mainly have three major components, compressor, condenser, evaporator, and other auxiliary components, including expansion valve, liquid storage dryer, pipeline, condensing fan, blower, temperature sensor, etc.
 
The role of components
 
The compressor is driven by the engine through the belt, and its function is to inhale the low-temperature and low-pressure refrigerant vapor, compress it to the required pressure, and send it to the condenser, which is the power source of the entire air-conditioning refrigerant cycle. The higher the engine speed, the faster the refrigerant cycle and the greater the cooling power.
 
 
The function of the condenser is to transfer the heat of the high temperature and high pressure gaseous refrigerant to the outside air to condense the refrigerant into a liquid.
 
The condensation effect of the condenser on the refrigerant directly determines the cooling efficiency of the air conditioner. There are generally three ways to improve the condensation effect: 1. Increase the flow of air through the condenser; 2. Reduce the temperature of the air passing through the condenser; 3. Keep the surface of the condenser clean and free of contamination.
 
 
The evaporator is usually arranged in the cab, and its function is to absorb heat from the cab, so that the liquid refrigerant is vaporized into gas.
 
 
The main function of the liquid receiver dryer in the air conditioning system is to filter, dry, dehumidify and store the excess refrigerant.
 
The expansion valve and the temperature sensor are generally installed on the evaporator, and the temperature sensor is usually located at the outlet of the evaporator to detect the outlet temperature of the evaporator, automatically adjust the opening of the expansion valve, and control the flow rate of the refrigerant to control the temperature in the cab. Stablize.
