Abstract: An energy recovery ventilator wherein two of the air flow openings are in direct communication with either the fresh air space or the stale air space. The energy recovery ventilator has a housing with at least a first face panel holding a heat exchange device. The housing includes two air flow openings in the first face panel of the housing, in direct communication with the stale air space, and two other air flow openings in the housing in communication with the fresh air space through duct pipes. Alternatively, the first two air flow openings are in direct communication with the fresh air space, and the other two air flow openings are in communication with the stale air space through duct pipes. The energy recovery ventilator also includes a hinged bar mounting system and a control system. The features of the present invention facilitate ease of installation.
