Abstract:

 

In this study, the use of R134a and R134a/R1234yf (10/90) refrigerants in a cooling system have been investigated theoretically. The energy, environmental and enviroeconomic analyzes of refrigerants have been performed for a cooling system. The energy performances of refrigerants have been made for different evaporator (between -10 oC and 5 oC) temperatures and a constant condenser (35 oC) temperature. The R134a/R1234yf (10/90) has a higher mass flow rate (26.50%) than R134a. Because R134a/R1234yf (10/90) has a lower refrigerating effect (evaporator enthalpy difference) than R134a. The R134a/R1234yf (10/90) has slightly higher compressor energy consumption (nearly 2.94%) than R134a, and so the COP of R134a has slightly (nearly 2.85%) higher than R134a/R1234yf (10/90). When compared to R134a, it is seen that the R134a/R1234yf (10/90) significantly reduces discharge temperature (about 16%). The environmental and enviroeconomic result values of R134a/R1234yf (10/90) are slightly higher than R134a. However, even the slight differences are significant to the evaluation of the environmental impact of refrigerants. It is seen that the wind energy source has the lowest environmental and enviroeconomic value and so the wind energy is the best environmentally friendly energy source according to the other energy sources.
