— one of the highest quality modern refrigerants: it is considered environmentally friendly, while it is completely homogeneous in composition, so it does not require replacement in case of partial leakage — refilling is enough. The main disadvantages of R134A are high cost, high operating pressure (which, in turn, affects the price of the cooling circuits themselves — they must be very reliable), as well as hygroscopicity due to the use of polyester oil.
