ENVIRONMENTAL REFRIGERANT INSTEAD OF HCFC-22

摘要

the invention proposes that ternary mixtures of fluorethan (hfc - 161), pentafluorethan (hfc 125) and difluormethan (hfc - 32) as an environmentally friendly alternative refrigerants and as a replacement for the connection - 22. the massenverhu00e4ltnisse each component are 5 - 60% and 25 - 50% and 5 - 50%. the odp is zero, without a verarmungspotential for the ozone layer occurs.its gwp are smaller than those of the connection 22, r407c and r410a. her operating pressure and pressure ratio is in the vicinity of the connection 22. this ersatzmischungen can be used instead of the connection 22, and the components of the system must be changed only slightly.
