Air conditioners with R410A refrigerant

R410А

— it is one of the environmentally friendly alternatives to R22 along with R407C. However, unlike the latter, the R410A refrigerant is azeotropic: it consists of components with the same evaporation characteristics. It ensures that the composition of the refrigerant does not change in the event of a refrigerant leak and the circuit can be topped up instead of having to be completely recharged. On the other hand, R410A is known for high operating pressure, which puts serious demands on the strength and reliability of the cooling circuit and increases its cost; and the refrigerant itself is quite expensive.
