Abstract

Abstract: R1234yf and R1234ze(E) are new environmentally friendly refrigeration working substances in heat pump hot water systems, but they are still less applied in heat pump water heater with storage tank. Therefore, the operating characteristics of R1234yf and R1234ze (E) in a storage-type heat pump water heater system was investigated. The effects of R1234yf charge amount and operating ambient temperature on its operating characteristics were experimentally studied. For the heat pump water heater system established in this study, the optimal R1234yf charge amount is 1000 g, with heating capacity of 5170 W and a heating COP of 4.24. Within the allowable range of the heat pump, higher ambient temperature leads to greater heating capacity and higher heating COP. A comparative study on the differences in operating characteristics between R1234yf and R1234ze (E) showed that R1234ze (E) has lower operating exhaust pressure and temperature when used in the heat pump water heater system, and has good application potential in high water temperature conditions.

Key words: R1234yf, R1234ze(E), Heat pump water heater, Performance study, COP
