1. What is the use of automobile air-conditioning refrigerant

The refrigerant of the air conditioner can cool the evaporator, and only in this way can the air outlet of the car air conditioner blow out cold air.

The refrigeration principle of the car air conditioner is very simple. After pressing the ac button, the compressor clutch will be combined. At this time, the engine will drive the compressor to run. The compressor can continuously compress the refrigerant and deliver the refrigerant to the evaporator.

The refrigerant expands continuously in the evaporator to absorb heat, so that the evaporator can be cooled, and the cooled evaporator can cool the wind blown by the blower, so that the air outlet of the air conditioner can blow out cold air.

To put it bluntly, the refrigeration principle of the automobile air conditioner is to use the conversion of the refrigerant form to cool.

If there is no refrigerant, the air conditioner will not be able to cool.

The heating principle of the car air conditioner is very simple. When heating, the high-temperature coolant in the engine will flow through the heater tank. At this time, the wind blown by the blower will also pass through the heater tank, so that the air outlet of the air conditioner can blow out warm air. up.

The refrigerant used in automotive air conditioners is r134a, which needs to be replaced regularly. If it is not replaced for a long time, it will cause the cooling effect of the air conditioner to deteriorate and the cooling speed to slow down.

Replacing the refrigerant requires the use of professional equipment, so car enthusiasts cannot replace it by themselves, and they can only go to some professional stores for replacement.

When buying refrigerants, it is also necessary to choose authentic products of big brands.

2. How to change the refrigerant of automobile air conditioner

There are two ways to replace the refrigerant, one is the high-pressure end charging method, and the other is the low-pressure end charging method. Both of these methods require professional equipment to complete, so if you want to replace the refrigerant Refrigerants need to go to a professional store.
There is refrigerant in the car air conditioner. If there is no refrigerant, the car air conditioner cannot be cooled.

The refrigeration principle of the car air conditioner is very simple. After pressing the ac button, the compressor clutch will be combined. At this time, the engine will drive the compressor to run. When the compressor is running, it can continuously compress the refrigerant and deliver the refrigerant to the evaporator.

The refrigerant continuously expands and absorbs heat in the evaporator, so that the refrigerant can cool the evaporator, and the cooled evaporator can cool the wind blown by the blower, so that the air outlet of the air conditioner can blow out cold air.

The refrigerant used in automotive air conditioners is r134a, which needs to be replaced regularly. If it is not replaced for a long time, the cooling speed of the car air conditioner will slow down and the cooling effect will deteriorate.

When replacing the refrigerant, you must go to a professional store. Car owners cannot replace it by themselves.

In the process of using the car, the refrigerant must be replaced regularly, and the air conditioning system must be cleaned and disinfected regularly.

When using the car at ordinary times, it is necessary to maintain it on time, replace the oil on the car on time, and replace the wearing parts on time, so that the car can always be kept in good condition.
