The reason why a refrigerator can cool is that it contains refrigerant inside the machine. But can a refrigerator keep cooling after being bought? Does the refrigerant inside need to be added? How can I add it? How often should it be added? Today, Zhonglian Energy will provide a detailed introduction to these issues for everyone.
Theoretically, there is no consumption of refrigerant in refrigeration equipment such as air conditioners or refrigerators, so there is no need to add additional refrigerant. However, if there is a refrigerant leak, it is necessary to add the refrigerant. Insufficient refrigerant without filling will lead to unsatisfactory cooling effect. Before filling, repair the leaking area first. Otherwise, it will still be leaked again after being added. Under normal circumstances, the refrigerant can be used until the compressor is naturally damaged and can no longer be used.
1. First, after the refrigerator has been emptied, use a combination gauge valve at the process port to charge it with liquid refrigerant at a low flow rate to 0.3MPa and let it stand for 5. After plugging in and running the refrigeration compressor for 15 years, adjust the working pressure at the process port.
2. First, observe the low pressure. If it is less than 0.06MPa, add gaseous refrigerant from the process port. As time goes by, the pressure will continue to drop, so add refrigerant again.
3.After automatic shutdown, it will automatically restart and continue to adjust the low voltage. Adjust the pressure to 0.06MPa before shutting down. It can be completed after a few rounds of repetition.
4. During the adjustment process, one needs to be careful. One or two adjustments will not be precise. When the pressure is relatively high, it can be directly discharged from the gauge valve without worrying about air mixing in.
5. The amount of refrigerant added to the refrigerator: There is a certain amount of refrigerant added to the refrigerator. Adding too little or too much refrigerant will affect the cooling effect of the refrigerator. Adding too much refrigerant may also cause damage to the refrigerator's compressor.
Although the process of adding refrigerant to a refrigerator or air conditioner seems simple, the actual operation is not an easy task with just one click. Safety issues also need to be considered. Here, it is recommended that professional guidance be sought when adding refrigerant to avoid inevitable accidents.
