What has changed in the corresponding refrigerator oil?
In the past, the corresponding R12 and R22 refrigerants were all mineral oil; Now car air conditioners use PAG synthetic oil; PVE and POE synthetic oil for our household air conditioners; It is possible to develop higher grade synthetic oils in the future.
Although mineral oil is low in cost, its life and performance are relatively poor compared with synthetic oil; We are now starting to focus on synthetic oil and supplement with mineral oil; Especially with the implementation of our new energy efficiency in July 2020, manufacturers will completely eliminate the R22 ratio in order to improve the energy efficiency ratio; Transferring to new refrigerants and environmentally friendly refrigerants, synthetic oil will become a trend and indispensable at this time.
