Abstract

A HVAC system for conditioning an interior zone includes an air handler configured to operate at least one of a plurality air distribution modules affixed to the air handler.

What is claimed is: 
     
         1 . A HVAC system for conditioning an interior zone comprising:
 an air handler configured to operate at least one of a plurality air distribution modules affixed to the air handler.   
     
     
         2 . The system of  claim 1 , further comprising an outdoor unit assembly operatively coupled to the air handler for exchange of a refrigerant therebetween. 
     
     
         3 . The system of  claim 1 , further comprising a conduit affixed to each of the plurality of air distribution modules to distribute air to an interior zone. 
     
     
         4 . The system of  claim 2 , wherein the outdoor unit assembly is selected from the group consisting of: a heat pump and an air conditioner. 
     
     
         5 . The system of  claim 1 , further comprising a ventilation device operatively coupled to the air handler for circulating fresh air to an interior zone. 
     
     
         6 . An air distribution module comprising:
 an enclosure having an interior volume, a distribution air inlet opening, and a distribution air outlet opening that are adapted for communication of a distribution air stream;   a damper, disposed within the enclosure, configured to operate between an open and closed position, and a number of positions therebetween; and   a fan, disposed within the enclosure, configured to circulate air through the enclosure   wherein the enclosure is configured to be affixed on an air handler.   
     
     
         7 . The air distribution module of  claim 6  further comprising:
 an electrical heating element, disposed within the enclosure, configured to provide auxiliary heat. 
 
     
     
         8 . An air handler comprising:
 a plurality of fans configured to provide and direct conditioned air or fresh air to respective multiple zones of a building.   
     
     
         9 . The air handler of  claim 8 , further comprising
 a first enclosure, wherein a coil and a controller are disposed within the first enclosure;   a plurality of second enclosures, wherein at least one of the plurality of fans is disposed inside each of the plurality of second enclosures; wherein each of the second enclosures are affixed to the first enclosure, and wherein the plurality of second enclosures are adapted for communication of a distribution air stream.   a damper disposed within each the plurality of second enclosures; wherein the controller is in operable communication with the plurality of fans and the damper.
