What is the refrigerator refrigerant, and how do I add refrigerant to the refrigerator?

If the refrigerator is operating normally but not cooling, it is likely that it lacks refrigerant. The refrigerant of the refrigerator is the basis for cooling. If you want the refrigerator to regain its cooling effect, you need to add refrigerant. Today Let's explain to everyone about refrigerator refrigerant.

First of all, what is a refrigerant?

Refrigerator refrigerant is generally called 'refrigerant'. It is a kind of refrigeration medium. It acts as a refrigeration medium by absorbing heat in the evaporator. The refrigerant is used in the evaporator and compressor of the refrigerator. , The condenser works cyclically to absorb heat, thereby regulating the temperature in the refrigerator.

How should refrigerant be added? To add refrigerant to the refrigerator, you must be familiar with the structure of the refrigerator. If you are familiar with the structure of the refrigerator, you can easily add refrigerant to the refrigerator. The first is to cut off the power supply, stop all the refrigerator systems, and then proceed to the next step after a period of time to prevent accidents. Then, when connecting the system, pay attention to close the high and low pressure valves, and then connect and lock the high and low pressure of the system. After connecting the injection port to the vacuum pump, the system can be vacuumed. When the system is programmed, open the locked high and low pressure valves to start the formal system evacuation work. If the refrigeration system has been pumped to vacuum, close the high and low pressure valves and then turn off the vacuum pump.

At this time, the refrigeration system is in a vacuum state, you can add refrigerant, disconnect the yellow tube from the vacuum port on the parallel port of the street refrigerant, open the valve core of the refrigerant bottle, and the air in the yellow tube After draining, put the refrigerant bottle upside down, and open the high and low pressure valve to add refrigerant.

After the refrigerant is almost added, close the high and low pressure valve and put the refrigerant bottle, so that the refrigerant addition to the refrigerator is completed.

Although the addition of refrigerator refrigerant looks simple, in fact it is easy to make mistakes in details, so it is recommended that you find professional personnel to add refrigerant. If you have confidence in yourself, you can also complete the addition of refrigerator refrigerant by yourself. .
