  • Control system for air quality and temperature conditioning unit with high capacity filter bypass
    Patent number: 5707005
    Abstract: An air conditioning unit is provided with a high capacity filtration system for removing pollutants from supply air, typically return air which has been recirculated from the conditioned area. A filter bypass passage and suitable flow control devices are provided so that supply air, typically fresh outdoor air, may be routed around the filtration system when minimal or no filtration is required. An air quality detector samples the air quality and positions the flow control devices to effect the most cost efficient operation of the air handling unit under the given operating conditions.
    Type: Grant
    Filed: September 17, 1996
    Date of Patent: January 13, 1998
