EXPERIMENTAL EVALUATION OF THE THERMAL CHARACTERISTICS OF R417A USED IN AIR SOURCE HEAT PUMP WATER HEATERS
ABSTRACT
In this paper, experiments were conducted to compare the thermodynamic performance of R417A used in air-source heat pump water heaters under two ambient temperature conditions of 20°C and 7°C, including discharge pressure, input power and COP, and the experimental results were analyzed. The results showed that the operation was reliable and that R417A is very suitable for heat pump water heaters. This study provides a promising alternative refrigerant to freon.
