R438A refrigerant to replace R22

R438A refrigerant is a suitable replacement for R22. The cooling capacity of R438A is not as high than that of R22, but the electricity consumption remains lower.

R438A as a replacement refrigerant

When using R438A, it should be noted that its cooling capacity is not as high as that of R22. Several compressor oils can be used with the R438A, so it is probably not necessary to change the oil previously used in the equipment.

Applications and use

R438A is a refrigerant suitable to replace R22 in DX water chiller systems, commercial, residential air conditioning and medium/low temperature refrigeration systems.
