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

Teorijska komparativna studija slucaja: modernizacija u kojoj se koriste ugljovodonici, DME (dimetil-etar) i njihove mešavine kao alternative HFC-u

Summary

This paper focuses on the natural alternatives: hydrocarbons DME and their mixtures. 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 an air-water heat pump which currently uses R134a as the working fluid. In order to implement the international Legislation, the R134a refrigerant will be replaced with a natural hydrocarbon or ecological refrigerant mixture (with better ODP and GWP). Another important aspect is that energy efficiency is directly related to global warming and greenhouse gas emissions.
