Experimental evaluation of R410A, R407C and R134a alternative refrigerants in residential heat pumps.

Number: pap. 2498

Author(s) : PARDO P., MONDOT M.

Summary

Alternative refrigerants with low-GWP are under investigation for residential heat pumps, air-conditioners and heat pump water heaters, since R410A, R407C and R134a have GWP of 2088, 1650 and 1430, respectively. In this study, five alternative refrigerants: R459A, R454B, R447A, HPR2A and R32 were investigated for the replacement of R410A in a 10 kW Air-to-Water (A/W) reversible heat pump. Two alternative refrigerants for R134a: R1234yf and R513A were tested in a split Heat Pump Water Heater (HPWH) having a water tank of 200 liters. R454C was evaluated as a possible alternative to R407C in a 3 kW Water-to-Air (W/A) reversible heat pump. A total of 8 alternative refrigerants with low-GWP were evaluated with not less than 114 performance tests. These experimental results will be useful for the HVAC community for facilitating the selection of the most promising candidates for drop-in replacement of R410A, R134a and R407C in residential heat pumps.
