Simulation of energy impact of an energy recovery ventilator in Northern housing

The single core Energy Recovery Ventilator (ERV) used in this study is equipped with defrost control that recirculates the exhaust indoor air, while keeps outdoor air intake damper closed. This strategy has disadvantage of reducing supplied to house, which may affect quality. First, paper presents new correlation-based models supply temperature T 2 after energy recovery during normal and operation modes based on laboratory experimental data. A pre-heating coil heats from temperature. Second, a house Montreal (4356 HDD) simulated as reference using TRNSYS program. Since program cannot simulate under mode, are connected equation boxes. use houses at three locations northern Canada HDD 8798 (Inuvik), 8888 (Kuujjuaq) 12208 (Resolute), also simulated, without ERV unit. seasonal for heating compared results Montreal. Compared case heat recovery, unit leads savings: 24% (Montreal), 26% 27% (Kuujjuaq), (Resolute). minimum standard requirements, airflow rate due reduced by 4.7% (223 hours) Montreal, 19% (1043 Inuvik, 13% (701 Kuujjuaq, (1379 Resolute.
