This study presents a comparison of energetic and exergetic performance of a vapour compression
refrigeration system using pure HC (hydrocarbon) refrigerants. In this study, three different pure HCs
propane (R290), butane (R600) and commercial LPG (liquefied petroleum gas) are used in the theoretical
analysis. R134a is also used in the analysis as a reference refrigerant. The evaporator temperature ranges
from 30 to 0 C while the condenser ranges from 30 to 50 C. MATLAB software is used for solving the
thermodynamic equations, while the thermo-physical properties are calculated using REFPROP software.
The results show that R600 has the highest COPc and exergetic efficiency, while LPG has the lowest.
When compared to R134a, the COPc for R134a is higher than that for LPG by 10%. Also, the exergetic
efficiency is higher by 5%. However, LPG has the advantage of being not expensive, available in large
amounts and zero ozone depletion potential and low global warming potential.
