Abstract
A refrigerant composition comprising difluoromethane (R-32), pentafluoroethane (R-125), 1,1,1,2-tetrafluoroethane (R-134a), and n-pentane, preferably prepared by mixing n-pentane preliminarily in R-134a, and mixing into a refrigerant of R-32 and R-125, with the n-pentane contained in a range of 0.1 wt. % to 14 wt. % of the total weight, and a refrigerating apparatus employing the refrigerant composition composed of above. It is an object of the present invention to develop a nonflammable refrigerant composition capable of using refrigerating machine oil such as mineral oil and alkyl benzene which is used in refrigerating apparatus, none in risk of destroying the ozone layer, excellent in cooling performance, superior in lubricating performance, and outstanding in heat resistance.
