Document Type Patent


Refrigerant compositions include mixtures of at least three different components, including a fluorinated sulfur-containing compound with at least one of a fluorinated ether or a fluorinated hydrocarbon. Also, methods for cooling a body include compressing such a refrigerant composition and bringing the body into heat transfer relation to it. The disclosed refrigerant compounds have refrigerant-significant properties similar to those of R-22, and they can be employed as drop-in substitutes in refrigeration apparatus designed for R-22 application.
