Abstract

In this study, energy and environmental analyses of R410A and its alternative refrigerants (R452B and R454B) in the heat pump system were performed. Environmental analyses of refrigerants were performed as stated by life cycle climate performance. R452B and R454B GWP rates are quite low compared to R410A or and their energy performance is slightly higher than R134a. A low GWP ratio of refrigerants is not the solution alone in reducing the carbon footprint of the heat pump system. In order to lessen the total carbon footprint of the heat pump, increasing the efficiency of the heat pump and environmentally friendly energy sources (wind, solar, geothermal energy sources, etc.) must be used.
