Use the matters needing attention of refrigerant R410A you want to know

r410a refrigerant is a new kind of environmental protection refrigerants, does not destroy the ozone layer, cooling or heating time, the working pressure for the common R22 air conditioner 1. Refrigeration (about 6 times, Warm) More efficient. Under the Chinese network to introduce the use of refrigerant R410A refrigerant considerations.

1 is higher than that of R22, R410A refrigerant pressure about 1. About 6 times. In the installation of air conditioning refrigerant R410A, using R410A special tools and materials, pay attention to safety operation.

2, mixed with the non-condensable gas such as air, will lead to abnormal high pressure refrigerant circulation pipeline, the circulation line is the main cause of fracture, crack.

3, when installing a yituo more air conditioning, due to the volume of the refrigerant sealed more, especially in the small room for installation, even one thousand refrigerant leakage occurs, its concentration cannot exceed the specified value. Otherwise, will cause the phenomenon of hypoxia.

4, in the use of R410A refrigerant in household air conditioner, cannot use the refrigerant R410A. In using R22 refrigerant air conditioner, also cannot use R410A refrigerant.

5, because is a kind of approximate azeotropic mixture refrigerant R410A, when add refrigerant, using liquid way add. ( When using gas way to add refrigerant composition change, lead to changes in the characteristics of air conditioning also. )

6, refrigerant leakage, if you can make sure the remaining refrigerant mixed with no condensate gas, liquid filling can be directly. The same set of machine this method can only be used three times.

7, R22 system compared with R410A special parts, compressors, R410A system must use R410A compressor, stop valve, four-way valve. The rest of the parts under the condition of meet the pressure with R22 general

8, please don't with other cold media, freezing oil. R410A special tools are mainly in the aspect of after-sales service, and the use of other refrigerant air conditioning, don't mix.

9, because before and use the other refrigerant, 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.

10, from the perspective of protection of atmospheric environment, you need to use the vacuum pump.

11, because refrigerant R410A is a kind of approximate azeotropic mixture refrigerant, HFC - it is 32 and HFC - 125 almost azeotropic binary mixture, its floating temperature below zero. 2℃。 R410A in refrigeration and air conditioning systems will not occur significant separation, which will not change the composition of refrigerant due to leak, so in the process of after-sales maintenance add, don't need to discharge off the rest of the refrigerant in the system.

above considerations about using R410A refrigerant is introduced here over, hoping to bring you some help, if you have a demand on refrigerant, welcome consultation discussion with us, we wholeheartedly at your service.

need huge investment, so it is important to shop with caution.
