Experimental investigation into the thermal performance of a residential hybrid ventilation system

Experimental investigation was used to characterise the thermal performance of the system, and to assess its potential to be used as a cool-air ventilation device. It was found that the hybrid system was capable of operating effectively to such a purpose. The system was able to provide an indoor/outdoor air temperature difference of 10 K across a range of air flows up to 120 L/s, in either heating or cooling mode.
