Abstract
In this article, the operating stability and application of a water-heat storage system for detecting frost formation in an air-source heat pump were investigated, and the most efficient initiation point of the defrosting cycle was determined. This method of using the mechanism of frost formation and hot-gas and reverse-cycle defrosting was investigated in terms of the operating stability of a heat pump. In this study, when the air-source heat pump is in heating mode, an analogized interrelation for the temperature and humidity of the outside air for frost cognition is determined from a psychometric chart. In this study, an air-source heat pump was applied to a water heat storage system and evaluated the performance of its operation. The performance of the air-source heat pump presented in this study had energy production about 18.6 per cent greater than that of a heat pump for which a time step method of defrosting was employed.
