Heat Recovery And Demand Ventiliation System
US Patent:
2012005, Mar 1, 2012
Filed:
Aug 26, 2010
Appl. No.:
12/807018
Inventors:
Richard S. Kurelowech - Phoenix AZ, US
International Classification:
F24F 7/007
US Classification:
454329
Abstract:
A ventilation system for an air conditioning system includes dampers, a heat exchange unit, and a control unit. One damper controls the flow of ambient air into the system. The other damper controls the flow of relief/exhaust air that is cannibalized from return air from a room or space being cooled (or heated) by the air conditioning system. The ventilation system utilizes a control algorithm in the control unit to calculate, at stepped spaced apart increasing room ventilation rates, increasing CO2 concentrations in the air in the room that are below a maximum desired CO2 concentration in a room. The control algorithm permits a control unit in the ventilation system to open and close the dampers to maintain a CO2 concentration in the room that is below the desired CO2 concentration level.
