Figure 1: An energy recovery ventilator (ERV) unit installed at an administration building in Massachusetts. The ERV exchanges heat between the outdoor air and the ventilation from the occupied spaces. It operates in air-side economizer mode when the outdoor air temperature is below 60°F and modulates the outside air damper and return air damper to maintain the mixed air temperature setpoint.
