System for increasing operating efficiency of an HVAC system including air ionization

摘要

Disclosed is an HVAC system having one or more air ionization devices for increasing operating efficiency and reduces overall cost by reducing the level of volatile organic compounds in recirculated building air. Also disclosed are combinations of heat exchangers operating in conjunction with ionization to further reduce operating costs. Included are various control sequences for a controller useful for managing air quality using CO2, VOC and other sensors to maintain air quality at reduced cost.

主权项

1. A method, comprising:
mixing an outside air from outside an enclosed space with a return air from within the enclosed space in an air mixing device, the air mixing device having an outside air regulating assembly and a return air regulating assembly to respectively direct therefrom a mixed air flow of outside air and return air into the enclosed space, and control a ratio of outside air to inside air within the air mixing device; detecting a saturation of one or more airborne contaminants in the enclosed space using one or more airborne contaminant sensors, wherein a controller is responsive to the one or more airborne contaminant sensors; ionizing the air in the air mixing device using an ionization device separate from the one or more airborne contaminant sensors; and controlling the outside air regulating assembly and the return air regulating assembly to include more outside air in the mixed air flow when the saturation of airborne contaminants in the enclosed space is above an upper setpoint using the controller.
