摘要
Governments around the world are establishing technological routes and tactics for low/zero-energy buildings to reduce emissions and energy use. This paper describes a hybrid renewable energy system developed for a net-zero energy low-rise residential building located in Shanghai, China. This hybrid renewable energy system consists of a water-based photovoltaic/thermal (PVT) collector and a ground water-source heat pump (GWSHP). The hybrid system is designed to produce heating, cooling and electricity during both winter and summer by using solar energy and ground surface water energy respectively. Firstly, field tests on the PVT collector and GWSHP were carried out to obtain their thermal performance, and then analytical models for the PVT collector and performance curve of the GWSHP were developed and validated by the experimental data. In addition, the balance between annual energy production and consumption was estimated to evaluate the applicability of this system for the on-grid net-zero energy residential building in Shanghai. It is shown that the detached house with the PVT-GWSHP system can provide 109.3% of total requirements for heating, cooling and electricity, and has potentials to realize the net-zero energy target.
