A water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space. A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system. Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water. The operation of the air handling unit and its associated air purification system are automatically monitored and regulated by a programmable air quality and monitoring and control system which is coupled to multi-parameter sensing apparatus that continually detects temperature, humidity and gaseous and particulate pollution levels present in the conditioned space or the air being delivered thereto from the air handling unit.

An air handling unit comprising: a housing having an inlet opening, an outlet opening, and an internal flow path extending between said inlet opening and said outlet opening; blower means for sequentially flowing air inwardly through said inlet opening, through said internal flow path, and outwardly through said outlet opening; air purification means, positioned in said internal flow path, for receiving pressurized liquid from a source thereof, creating a spray from the received liquid, using the spray to purify air traversing said internal flow path, and then permitting the sprayed liquid to drain therefrom; sump means for holding a supply of liquid to be operatively supplied to said air purification means, and for receiving liquid draining from said air purification means; filter means having therein a filtering flow path through which liquid may be forced to trap pollutants from the liquid, and a backwashing flow path through which liquid may be forced to cleanse said filter means of trapped pollutants; a pump having an inlet communicatable with liquid in said sump means, and an outlet; conduit means interconnecting said pump outlet with said filtering flow path and said backwashing flow path, and said filtering flow path with said air purification means, switching means coupled with said conduit means and being selectively operative in a first mode to cause sump liquid discharged from said pump to be forced through said filtering flow path to said air purification means, or in a second mode to cause sump liquid discharged from said pump to be forced through said backwashing flow path; first monitoring means for detecting a change in an apparatus operating parameter, indicative of a predetermined lessening in the filtration efficiency of said filter means, and temporarily changing said switching means from said first mode thereof to said second mode thereof; and second monitoring means for detecting a change in selected environmental operating parameters and responsively controlling the operation of said air handling unit and said air purification means to maintain said selected environmental operating parameters within predetermined ranges therefor, said second monitoring means including: multi-parameter sensing means for sensing the level of at least one pollutant in air discharged from said air handling unit and responsively generating a sensed parameter signal, and air quality monitor and controller means, interconnected between (1) said multi-parameter sensing means and (2) said air handling unit and said air purification means, for receiving said sensed parameter signal and responsively generating system output control signals operative to regulate the operation of said air handling unit and said air purification means.
