And secondly, the features of the HC procedure (decreased condensing place, constructive thermodynamic attributes, and remarkable COP [Coefficient of Overall performance]) act in combination to improve energy-efficient operation. As an illustration, the use of propane (R290) as an air‐conditioning substitute for an HFC-134a process would return a bare minimum GHG https://co2heatpumps76419.tkzblog.com/18386463/not-known-factual-statements-about-co2-heat-pumps
