Abstract
The paper presents a brief review on the utilization of HFO refrigerants on split residential air conditioners and heat pumps. A description of currently available HFO refrigerants and their mixtures is presented. Baseline refrigerants, mostly HFCs and HCFC, find a distinct substitute, depending on application and manufacturer. The overall performance of this class of refrigerants is discussed regarding different criteria, namely: energy efficiency, environmental impact, flammability, manufacturers and costs. In future, the choice of refrigerant for residential air conditioners and heat pumps, from eitherR32, hydrocarbons or HFOs, will be dictated by cost (both operational and capital), flammability issues and stricter legislation concerning maximum allowable GWP.
