What does refrigerator refrigerant mean? How much refrigerant is suitable for the refrigerator?
If the refrigerator is operating normally in other aspects but does not cool, it is likely that it lacks refrigerant. The refrigerant in the refrigerator is the basis for realizing refrigeration. If you want the refrigerator to regain its refrigeration role, you need to add refrigerant. Let’s talk about refrigerator refrigerant today.
First of all, what is a refrigerant?
Refrigerator refrigerant, we generally call it “snow seed”. It is a refrigeration medium that absorbs heat in the evaporator to play a cooling role. The refrigerant cycles in the evaporator, compressor, and condenser of the refrigerator to absorb heat, thereby adjusting 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 and stop all the refrigerator systems. After a period of time, we will proceed to the next step to prevent accidents.
Then, when connecting the system, pay attention to close the high and low pressure valves first, then connect the high and low pressure of the system and lock them tightly. After connecting the injection and connection to the vacuum pump, the system can be vacuumized.
When the system is pumping the program, open the locked high and low pressure valves and start the formal system pumping 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, so refrigerant can be added. Disconnect the yellow tube from the vacuum book and connect it to the parallel port of the refrigerant. Open the valve core of the refrigerant bottle. After exhausting the air in the yellow tube, turn the refrigerant bottle upside down. Put it in place and open the high and low pressure valves to add refrigerant.
After the refrigerant is almost added, close the high and low pressure valves and place the refrigerant bottle, so that the addition of refrigerant in the refrigerator is completed.
Although the addition of refrigerator refrigerant may seem simple, the details are actually easy to make mistakes, so it is recommended that you find a professional person to add refrigerant. If you are confident in yourself, you can also complete the addition of refrigerator refrigerant yourself.
