In this study, the thermal impact of defrost cycle of both residential heat and energy recovery ventilators (HRV and ERV) was investigated using TRNSYS. The thermal efficiency patterns of the units were obtained from winter experiments, and then implemented into the existing HRV and ERV models for simulations in the context of airtight environment. Throughout the heating season, the minimum humidity...
The potential of conventional heat/energy recovery ventilators have been widely studied, whereas the impacts of defrost cycles are usually neglected. An energy recovery ventilator (ERV) was studied in the Archetype Sustainable House-B (ASH-B) located in Toronto, Ontario. The study provides an experimental evaluation of the efficiency of the ERV unit during normal and defrost operations, as well as...
