Performance of Air Based BIPV/T Heat Management Strategies in a Canadian Home

摘要

Using TRNSYS, the performance of three heat management strategies of an air-based Building Integrated Photovoltaic/Thermal (BIPV/T) system in an energy efficient home are assessed. The first scenario makes direct use of the heated air as fresh air supplied to a heat recovery ventilator. The second scenario uses the heated air from the BIPV/T collector as a source for the outdoor unit of an air source heat pump. The third strategy involves storing the energy from the BIPV/T collector heated air in an ice-slurry latent storage tank that is coupled with a water source heat pump. These strategies are evaluated in reference to a base case scenario with a simple air-based ducted system without a BIPV/T collector. Results show that using a latent storage medium such as ice can potentially bridge the time gaps between available solar radiation and domestic space heating loads.
