摘要

The composition, composition refrigerant or heat transfer fluid, azeotropic or near azeotropic composition, processes for the production of refrigeration, heat production, heat transfer, and methods for the production of refrigeration or air conditioning The.For the detection of a leak and heat production is about compositions refrigerant and heat transfer fluid comprising the 1,1,1-trichloroethane, 2,2,4,5,5,5 - nonafluoro - 4 - (trifluoromethyl) - 3 - pentanona and at least one hidrofluorocarbono for use in refrigeration systems and the R conditioning through the employment of a centrifugal compressor.The composition may be azeotropic or azeotrope like.
