Refrigerant blends: new superheat and subcooling calculation methods.

Type of article: Article

Summary

As refrigerant binary and ternary mixtures begin to replace CFC compounds in some refrigeration applications, it is important that the installing engineer and service technician understand the possible glide in both evaporating and condensing temperatures. The author illustrates the effect of using a blend of R22/R152a/R124 known as MP39 at known operating pressure levels. Subcooling and superheating are discussed, also change of lubricant. D.W.H.
