the United States lead is developing a late-model refrigerant as an alternative for R134a generally used in automotive air-conditioning.The relevant ... LL Wang,YT Ma,MX Li,... - 《Journal of Engineering Thermophysics》 被引量: 4发表: 2009年 Cryogenic-grinding by Effective Utilization of Liq...
Also, the developers maintain that due to its greater compatibility with R134a it could be used as an environmentally friendly solution for various HFC134a applications with minor modifications.The blend has also been bench-tested under summer and winter conditions as a “drop-in” in a heat ...
Three red flags on this topic include: The beginning of production of automo-tive air conditioning in Europe using HFO-i234yf rather than HFC-i34a. An announcement from the United States Environmental Protection Agency that it has given "final approval for a new refriger-ant (HFO-i234yf) ...
Since no upgrade is required, MULTICOOL refrigerants are the perfect solution for any system that previously used gases such as CFC R12, HFC R134a, HCFC R22, R502, R11 and others. Because of this compatibility, it is easy for companies to move away from the harmful and destructive products...
