How much money a car air conditioning compressor?
Car air conditioning compressor 1200-1800 yuan a:
Falling off and forgetting to turn off the air conditioner is not as serious as we thought.
Many people always forget to turn off the air conditioner when the engine is turned off. Some car owners worry that the air conditioner compressor will run when the engine is started again, which will increase the burden on the starter and battery.
The principle of temperature regulation of "pit father"
If your car has a fixed displacement compressor, it is most cost-effective to adjust the temperature to the lowest when the air conditioner is turned on.
Air conditioning compressors also have "lubricating oil"
When the air-conditioning compressor is working, there are many internal parts rubbing against each other, so it also needs lubricating oil to lubricate. This kind of oil is resistant to low temperature and is generally called refrigerating oil. The lubricating oil of the compressor does not need to be changed regularly.
Most cars have observation holes in the air conditioning pipes
Refrigerant is the basic guarantee for the normal operation of automobile air conditioning system. It is not good to have more or less refrigerant. General repair shops will determine the amount of refrigerant by detecting the pressure of the air conditioning system. In fact, most vehicles have a transparent observation hole on the air conditioning pipeline, which allows us to easily check the refrigerant margin without any auxiliary tools.
Variable displacement compressors are not necessarily fuel efficient
Nowadays, many cars are equipped with variable displacement compressors. Many people think that this is the same as inverter air conditioners to save fuel. In fact, it is not, the variable displacement compressor is mainly to improve comfort.
Air conditioning compressor is not always running
For the fixed displacement compressor, the compressor is not always working when the air conditioner is turned on, but works for a while and stops for a while. Because if the compressor keeps working, there will be liquid refrigerant continuously vaporizing and absorbing heat in the evaporator, and there is a lot of condensed water on the surface of the evaporator. When the temperature is close to zero, the condensed water will frost and the evaporator will be completely blocked., The air conditioner will not blow out.
How does the car air conditioner make air conditioning?
The principle of automobile air conditioning can actually be described in very simple language, that is, the compressor drives the refrigerant to circulate in the air conditioning pipeline. One part of the air conditioning pipeline is inside the car and the other part is outside the car. The refrigerant changes from liquid to gaseous in the evaporator in the car to absorb heat to produce low temperature, and then the gaseous refrigerant is compressed by the compressor, liquefied in the condenser outside the car, releases heat and becomes liquid again, and then enters the car again. Gasification absorbs heat inside. In this way, the heat in the car will be transferred to the outside of the car little by little, and the inside of the car will naturally cool off.
