A Study on Experimental Performance of Air-Type PV/T Collector with HRV

To improve indoor air quality, appropriate ventilation is essential. Ventilation, somewhat contributes to heat loss. Heat recovery ventilation (HRV) system presents solutions to exchange discarded heat of exhaust air with incoming outdoor air. Photovoltaic/thermal (PV/T) system is the technology for producing electricity in PV module and using heat at the back side of the panel for hot water heating system simultaneously. Heated air from an air-type PV/T can be coupled with HRV system for preheating instead of outside air intake. Thus the ventilation efficiency can be improved. With heated air of an air-type PV/T collector, freezing and dew condensation problems in traditional HRV system caused by low temperature air during winter, can be resolved. The performance of air type PV/T collector coupled with HRV has been studied experimentally. (C) 2015 The Authors. Published by Elsevier Ltd.
