Refrigerant R410a and R22 refrigerant installation and maintenance matters needing attention

small make up today for everyone to introduce refrigerant r410a and R22 refrigerant installation and maintenance matters needing attention, want to know friends votes followed the introduction of small make up have a look at the following article.

1, higher than R410a refrigerant R22 refrigerant pressure about 1. About 6 times, when installing a R410a refrigerant air conditioning, using R410a special tools and materials, pay attention to safety operation.

2. Please don't to outside air mixed with air conditioning refrigerant R410a refrigerant circulation line. If mixed with air and gas, will lead to abnormal high pressure refrigerant circulation pipeline, the main cause of the circulation line rupture, crack.

3, if the refrigerant leakage in indoor, once contact with open flame will form of toxic gases.

4, and other cold media use before different, vulnerable to moisture, oxidation layer, grease, etc. The influence of impurity content, so that full attention should be paid during operation, use clean pipe, prevent moisture, etc.

5, because the R410a refrigerant is an analog azeotropic mixture refrigerant, when add refrigerant, using liquid way add. Said in add refrigerant with a refrigerant container and electronic, according to the weight measurement.

6, use air conditioning, a R410a refrigerant pressure than traditional R - 22 a much bigger air conditioning refrigerant, therefore, in choice of materials, must be compatible with R410a. In the market to buy the wall thickness of 0. 7 mm copper tube, cannot use.

7, R410a refrigerant pressure is higher, cannot use the before even more inventory. High standard and the low pressure table difference with previous products. When buying pressure gauge can refer to the following parameters.

8, in the refrigerant R410a but mixed with vacuum pump oil ( Mineral oil) , will produce chemical reaction, generate sludge, cause the damage of the air-conditioning unit.

9, R410a refrigerant container, direct use of refrigerant in the name of the annotation, at the same time, also according to the requirements of the United States ARI color annotations ( Pink) 。

R - before 10, cannot use The detection of 22 products. Use high sensitivity for HFC refrigerant leakage detector.

the above refrigerant R410a and R22 refrigerant installation and maintenance matters needing attention introduced over here, hope to be able to bring you some help, if you have a demand on refrigerant, welcome consultation discussion with us, we wholeheartedly at your service.

start capacitor suppliers are required in the manufacture of almost every product and start capacitor suppliers refrigerant gas is one of the most common machines.
