Design and performance evaluation of building integrated PVT and heat pump water heating (BIPVT/HPWH) system

Abstract

This paper presents the design and performance evaluation of a building integrated photovoltaic/thermal and heat pump water heater (BIPVT/HPWH) system. The system performance is evaluated using the proposed BIPVT/HPWH model with a user-friendly graphic user interface like Simulink block libraries. Integrating with a HPWH system, the BIPVT modules are designed for both solar electricity and thermal collector that offer heat and power consumption of heat pump for water heating. This makes refrigerant efficiently evaporated by solar energy and PV efficiency consequently enhanced with waste heat removal by refrigerant. The results of performance evaluation reveal that the average coefficient of performance (COP) achieves up to 6.7.
