What is an automotive compressor assembly
Automobile Compressor assembly is a key component in the air conditioning refrigeration system of an automobile. Its main function is to compress and deliver refrigerant vapor and maintain the circulation of refrigerant in the refrigeration system. The automotive compressor assembly is usually composed of the following main parts:
Youdaoplaceholder0 Housing : As the main body of the compressor, it provides the necessary support and protection .
Youdaoplaceholder0 Piston or scroll plate : Pistons are used in reciprocating compressors, and scroll plates are used in scroll compressors. They move within a housing to compress or expand gas .
Youdaoplaceholder0 Valve : Controls the flow direction of gas as it enters and exits the compressor. It can be single-acting or multi-acting .
Youdaoplaceholder0 Shaft and bearings : Support the piston or scroll plate, reduce friction and prevent shaft wear .
Youdaoplaceholder0 Seal : Prevents gas from leaking inside the compressor or external air from entering the compressor .
Youdaoplaceholder0 Cooling system : Removes the heat generated by the compressor during operation from inside the compressor to prevent overheating .
Youdaoplaceholder0 Control system : Controls the operation of the compressor, including start, stop and speed regulation .
Youdaoplaceholder0 Power input : Power is usually provided by an electric motor, an internal combustion engine or a crankshaft driven by a belt .
In addition, automotive air conditioning compressors are divided into two types: fixed displacement and variable displacement, respectively suitable for different working conditions and requirements .
The main function of the automotive compressor assembly is to maintain the circulation of refrigerant in the system to ensure the effective cooling of the automotive air conditioning system . Specifically, the compressor achieves the cooling effect inside the vehicle by compressing and transporting the refrigerant, causing it to circulate between the evaporator and the condenser.
The working principle of the compressor is as follows:
Youdaoplaceholder0 Compressed refrigerant : In the evaporator, the refrigerant absorbs heat and turns into gas. The compressor sucks in this low-pressure, low-temperature gas, increases its pressure and temperature through mechanical action to turn it into high-temperature, high-pressure gas, and then sends it to the condenser .
Youdaoplaceholder0 Transporting refrigerant : In the condenser, the hot and high-pressure refrigerant gas undergoes a heat dissipation cooling process to become liquid, and the heat released is discharged outside the vehicle. The liquid refrigerant then enters the evaporator through the expansion valve, absorbs heat from the vehicle again and evaporates into gas, thus completing the refrigeration cycle .
Youdaoplaceholder0 Regulating start-stop state : The compressor can also regulate its own start-stop state. By adjusting the pressure in the air tank, the compressor can stop and rest, thereby providing some protection for the engine .
In addition, the automotive compressor assembly also has the following characteristics:
Youdaoplaceholder0 There are various types : Common compressors include reciprocating and rotary types, among which reciprocating types include crankshaft connecting rod type and axial piston type, and rotary types include vane type and scroll type .
Youdaoplaceholder0 Control mode : The control mode for fixed-displacement compressors and variable-displacement compressors is different. The exhaust volume of a fixed-displacement compressor increases proportionally with the engine speed and cannot automatically change the power output, which affects the engine fuel consumption. Variable displacement compressors can automatically adjust power output according to set temperature .
