Estimating the term…
In an air conditioning system which includes a catalytic air purifier, a control system is provided for sensing the level of predetermined conditions in a space and for responsively modulating the air purification process in a manner which optimizes the process in terms of its effectiveness and its economical use. The conditions that are sensed include the levels of VOC's, CO2, and biological contaminants, as well as degree of occupancy, relative humidity and air flow. The air purification process is modulated by varying the power to a UV lamp, turning one or more UV lamps on or off, varying the effectiveness of the catalyst, varying the volume or speed of the air flowstream and/or varying the relative humidity in the space.
A control for an air treatment system of the type having a return air duct, a supply air duct, a fan for causing air to be circulated through the system, and an air purifier within the system having at least one catalytic coated substrate with which the circulated air comes into contact, and at least one UV lamp disposed near the substrate for illumination thereof for oxidizing organic compounds in the circulated air, comprising:
A method of controlling an air treatment process in an air conditioning system of the type having a fan for circulating air to a space to be conditioned and a photocatalytic air purifier disposed in a flowstream of said air for purifying said air, comprising the steps of:
