| Abstract | In cold climates, the defrost strategies of the dominant conventional single core heat/energy recovery ventilators (HRVs/ERVs) involve the recirculation of exhausted (return) warm air across the heat exchanger core and back into the supply air for the house. In harsh cold climates, this type of defrost strategy can undermine ventilation performance. A dual core ERV design could overcome this issue by providing continuous ventilation. It has a potential to perform better than a conventional single core unit and meet the rigorous requirements for operation in the Canada’s North. This paper provides an experimental comparison of the efficiency between single and dual core ERVs using the twin houses at the Canadian Centre for Housing Technology (CCHT) as a test bed. The side-by-side testing also provided valuable data to measure the impact of the installation of a dual core ERV in a real residential application. Both houses were operated identically and monitored for a range of winter weather conditions. Changes in test house performance due to the innovative dual core design were observed and compared to the performance of the reference house. The parameters that were compared include: efficiency, airflow, indoor temperature and relative humidity, and energy consumption. This paper discusses the effectiveness of the dual core design ERV, energy use of the house and the ventilation rate. |
