Abstract
According to EU regulations, restrictions on the use of refrigerants with high
greenhouse effect was begun to seek alternative refrigerants. A comparative energy
and exergy analysis of R124zd (E) fluid heat pump systems with low greenhouse effect
instead of R134A fluid was done. The EES program was used in the analysis. Instead
of conventional heat pump systems, parallel heat pump system and heat exchanger
heat pump system were used. During the analysis, different evaporator temperatures,
condenser temperatures, superheating temperatures, and changes in compressor
efficiencies over the heating power coefficient were investigated. When two systems
were compared, it is seen that the parallel connected compressor heat pump system is
more efficient than the heat exchanger heat pump system. When comparing fluids, it is
concluded that the R1233zd (E) fluid was an alternative to the R134A fluid. The results
were shown in graphical form. As a result, it is aimed to be a current work on the use of
alternative fluids to be used in industrial applications and in the future .
