Patent number: 8544288Abstract: The present invention provides a method for enhancing dehumidification of a conditioned space, while optimizing the effectiveness of Indoor Air Quality (IAQ) devices that are present in the HVAC system. After the system compressor is shut off, the actual space humidity is compared to the desired humidity. If the actual humidity is very close to or lower than the desired level the indoor blower (air handler) is allowed to continue running. However, if the actual humidity is greater than the desired level by a specified amount, the blower is forced off for a period of time proportional to the difference between the actual and desired humidity. At the next compressor activation, the blower is allowed to run as normal.Type: GrantFiled: October 2, 2006Date of Patent: October 1, 2013Assignee: Lennox Manufacturing Inc.Inventor: Virginia N. MacDonald

Patent number: 7549842Abstract: A housing cooperates with an air mover rotating about a rotation axis to move air received from an approach to an exhaust. The approach is generally oriented about a direction intersecting the housing at upstream and downstream limits. The housing presents an interior surface establishing radii between the axis and the surface. The radii have a generally constant radial value across a width in planes containing the axis in a first zone between the downstream limit and a first locus, and in a second zone between a second locus and the exhaust. The radii vary between a smallest and a largest radius across the width in planes containing the axis in a variance zone upstream of the axis. The smallest radius is less than the radial value at the first and second loci. The largest radius is larger than the radial value at one of the first and second loci.Type: GrantFiled: February 17, 2006Date of Patent: June 23, 2009Assignee: Lennox Manufacturing, Inc.Inventors: Oved W.
