What is the car air conditioning pump support
Automobile air conditioning pump , also known as air conditioning compressor, is the core component of automobile air conditioning refrigeration system. Its main function is to compress the low temperature and low pressure refrigerant gas into a high temperature and high pressure gas to provide power for the circulation of refrigerant. The air conditioning pump is located between the condenser and the evaporator and is responsible for transferring the refrigerant from the evaporator to the condenser .
Working principle
The working principle of the air conditioning pump is to achieve the cooling effect by compressing the refrigerant. The specific process is as follows:
Compressed refrigerant : The air conditioner pump inhales the gaseous refrigerant and compresses it to increase its pressure and temperature.
cooling liquefaction : high pressure and high temperature refrigerant through the cooler into liquid.
expansion heat absorption : The liquid refrigerant expands through the expansion valve and absorbs heat to turn into a gaseous state.
cycle refrigeration : gaseous refrigerant is compressed again, cycle to achieve the cooling effect .
Type and structure
Air conditioning pumps can be divided into constant displacement compressors and variable displacement compressors according to different working principles. Constant displacement compressor displacement is fixed, can not automatically adjust the power output according to demand; The variable displacement compressor can automatically adjust the power output according to the set temperature, more efficient and energy-saving .
Common faults and maintenance methods
Common faults of air conditioning pumps in the process of use include jamming, leakage, poor operation and abnormal sound. Sticking is usually due to poor lubrication; The leak may be a leak of oil or gas; Poor operation will lead to high temperature steam; Abnormal noise may be related to clutch slip or drive belt wear .
To prevent these faults, it is recommended to replace the air conditioner antifreeze regularly, keep the system clean, add refrigerant and lubricating oil appropriately, and check the pump operating status regularly.
To be specific:
Fixed compressor : air conditioning pump support By fixing the compressor to ensure that it does not shift or shake during the working process, so as to ensure the stable operation of the air conditioning system .
reduce vibration and noise : air conditioning pump will produce vibration and noise when working, support through its structure and material design, can effectively reduce the transmission of these vibration and noise, avoid the impact on the cockpit, improve driving comfort .
The main function of the automobile air conditioning pump is to circulate refrigerant, so as to achieve the cooling effect of the air conditioning system . When the air conditioner is turned on, the compressor clutch plate rotates with the engine, the electromagnetic clutch is energized, the belt pulley is sucked to the suction cup by the magnetic force of the electromagnetic coil, and the compressor begins to rotate. Through the action of the pump, the refrigerant circulates in the system, so as to achieve the purpose of reducing the temperature in the car .
In addition, the automotive air conditioning pump also has the following functions:
Drive the coolant to heat the engine : the automobile air conditioning pump helps the engine heat dissipation and prevents the engine from overheating by driving the coolant to circulate in the engine cooling system.
improve energy efficiency and reduce energy consumption : heat pump air conditioning use the reverse circulation principle, from the low temperature object to absorb heat and transfer to the high temperature object, only a small amount of reverse circulation work is consumed, you can get a larger heat supply, so as to achieve the purpose of energy saving .
intelligent control : Modern automobile air conditioning systems usually have intelligent control functions, which can automatically adjust the temperature and humidity according to the environment and use needs of the car, providing a more comfortable and personalized driving experience .
