Energy Performance Investigation of PVT Assisted Heat Pump System for a Net Zero Office Building
Abstract
This paper investigated the energy saving potential of the photovoltaic and solar thermal panel (PVT) assisted multi-source heat pump system for net zero office buildings. We proposed the schematic of the PVT assisted multi-source heat pump system to serve heating and domestic hot water load. The energy saving potential of the proposed system was also analyzed by simulation research compared with the conventional system. The conventional system composed of the air-source heat pump integrated with PV system. It was found that the proposed system can save 33% of operating energy consumption compared with conventional system. The renewable energy penetration rate of the proposed system showed 14.8% higher than the conventional system.
