What type of refrigerants are used in Midea air-conditioners?

Date added: 12.11.2020

Midea units operate with R32 and R410A refrigerant.

The refrigerants in some indoor units are interchangeable. How are they different? The R32 refrigerant is homogeneous, i.e. it consists only of itself, while the R410A refrigerant is a mixture of refrigerants (50% R32 and 50% R125). The mixture of factors will always be a less effective solution due to the possibility of the phenomenon of "Temperature Slip", that is, for example, evaporation of individual components of the R410A refrigerant at different temperatures, which may cause dysregulation of the system operation and obtaining worse operating parameters. The R410A refrigerant is classified as A1 category of refrigerants, i.e. non-flammable refrigerants, and the R32 refrigerant is classified as A2L category - slightly flammable refrigerants. Importantly, both factors have diametrically different GWP (Global Warming Potential) values

- R32: GWP = 675

- R410A: GWP = 2088

This means that the emission of 1 kg of R32 or R410A refrigerant will have the same effect as the emission of carbon 2-monoxide (CO2) into the atmosphere in amounts of 675 kg (R32) and 2088 kg (R410A), respectively.
