Theoretical comparative study case, hydrocarbons and HFC mixture alternatives retrofit.

Summary

This paper focuses on the natural alternatives: hydrocarbons and their mixtures (HC-290 and HC-600a). None of the above refrigerants is perfect; they all have both advantages and disadvantages, which must be taken into account by governments, equipment manufacturers, and ultimately by their users. Determination of thermodynamic properties and calculation of COP for natural alternatives and mixture were done using the Refprop and EES software. The theoretical study analyzes a heat pump air-water who works in present with R134a. To implement international Legislation, in the future is necessary to retrofit R134a refrigerant with a natural hydrocarbons or ecological refrigerant mixture (with better ODP and GWP). Energy efficiency is directly related to global warming and greenhouse gases emissions.
