HVAC • Energy Recovery Ventilation Systems

Energy recovery ventilation systems transmit energy contained in exhaust air and recycle it to treat incoming outdoor ventilation air.

  Energy recovery ventilation systems offer a controlled method for ventilating a home while minimizing energy loss. During the winter months, warm inside air is exhausted to the fresh, cold supply air in order to warm it. During the summer months, cold inside air is exposed to the warm supply air to cool it. Energy recovery systems are typically sized to ventilate a whole house at a minimum of 0.35 air changes per hour. There are two main types of energy recovery ventilation systems: heat-recovery ventilators (HRV) and energy-recovery ventilators (ERV). The principle difference is in the heat exchanger. The ERV’s heat exchanger transfers some water vapor along with the heat, thereby controlling humidity and preventing freezing. By contrast, the HRV transfers only heat. Leading manufacturers: RecoupAerator by UltimateAir, Lennox, Airxchange, Carrier and Aprilaire.
