Abstract

There is a growing awareness of the importance of using clean and environmentally friendly sources of energy. This paper presents the development of an intelligent energy saving heat pump for a water heater with a fuzzy logic controller that analyzes the heating efficiency of the heat pump heater. The fuzzy logic controller is employed for developing a heating algorithm to raise the efficiency of the heat pump heater and suppress unnecessary heating at high temperatures. Experimental results show that our heat pump heater produces an energy saving of 60% of total energy input, compared to the 23% for a gas heater operating at the same temperature. The system can work throughout the year and provide users with water at a required temperature. In winter, the Coefficient of Performance (COP) of the heat pump heater can reach a range of 2.1-2.5, while in summer it achieves around 2.61-2.95.
