Fantech's answer to a heat recovery ventilator (HRV) for house projects that demand higher efficiency, the VHR 150R with oval collars is designed for higher static pressure applications and is Energy Star qualified. The unit brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. During winter, fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs, while during summer, the incoming air is pre-cooled if the house is equipped with an air cooling system. The VHR 150R with oval collars incorporates a unique and quiet internal recirculation defrost that does not depressurize the home during the defrost cycle.
During the defrost sequence, a motorized damper temporarily blocks the incoming fresh air stream so that the warm air from the house can circulate through the HRV. The exhaust blower shuts down and the supply blower switches into high speed to maximize the effectiveness of the defrost strategy.
