Fresh air heat exchanger with air treatment system

Abstract

The fresh air heat exchangers function to supply ventilation, heating and air purification. The device does this whether the building is occupied or empty. The outside air is drawn in, filtered, then passed through the heat exchanger where room air is passed adjacent to it and its heat is extracted and transferred to the incoming fresh air. The room air is subsequently exhausted outside. The preheated fresh outside air continues on to a hot water coil where it is additionally heated and then passed over a UV cell for purification. The purified heated air is introduced to the room. In the building unoccupied phase, room air is cycled back into the room without bringing fresh air in.

1 . A mode switching fresh air heat exchanger having simultaneous movement of the hot air and cold air comprising:
 a housing, said housing having a front, a back, a top, a bottom, a near end, and a distal end;   located in the interior back of the housing, a fresh air exterior opening louver panel;   a first duct to carry the fresh air from the louver panel to a first heat recovery ventilator;   located in the interior front, near the bottom, a stale air open grill;   located interiorly to the housing and adjacent to and aligned with the grill, a filter for the stale air;   a second duct to carry the filtered air to a second heat recovery ventilator connected in air carrying tandem to the first heat recovery ventilator;   a third duct to carry the heat recovered air to the outside through the louver panel;   a fourth duct to carry the fresh air to a heating zone and through an air vent into a room, said air vent located in the top of the housing, said air being conveyed through the heating zone by a variable speed electrical fan;   said fresh air and stale air being simultaneously moved by electrical blowers, and   electrical components for electrifying the blowers and fans.   
     
     
         2 . The fresh air heat exchanger as claimed in  claim 1  wherein in addition, there is a cell for treating the air to substantially remove odors, pollutants, volatile organic compounds, smoke, mold, bacteria, and viruses, if present in the air. 
     
     
         3 . The fresh air heat exchanger as claimed in  claim 1  wherein, in addition, there is an air conditioning unit added to cool the air.
