Résumé

Using common refrigerants such as R410A in air conditioning systems leads to climate change due to their high global warming potential (GWP). Therefore, restrictive laws have been enacted to force manufacturers to use refrigerants with lower GWP than that of R410A. This simulation study explores the effects of substituting R410A with R468C on the performance of a fin-and-tube evaporator coil. A validated segment-by-segment heat exchanger model is used to find the optimum performance of using R468C as a working fluid by changing the heat exchanger circuitries. The results show that for identical superheat temperature (SHT) and saturated suction temperature (SST), R468C required a higher refrigerant flow rate, resulting in an increased cooling capacity (between 30-57%) and a lower coefficient of performance (about 10%) than R410A.
