Air handler and insert for the same

Abstract

An air handler and an insert for the same are provided. The air handler has a housing, an air conditioning element, and a first air outlet in the housing. The air conditioning element is disposed in an air passage in the housing through which air is moved by a fan. At least one wall of the air passage within the housing tapers the air passage between the air conditioning element and the first air outlet.

1 . An insert for an air handler, comprising:
 a first end having a first opening therein for receiving conditioned air and a periphery being dimensioned to correspond substantially to the interior dimensions of a plenum of an air handler downstream of an air conditioning element;   a second end having a second opening therein for permitting the conditioned air to exit the insert; and   at least one wall extending between the first end and the second end defining a first air passage tapering from the first opening to the second opening.   
     
     
         2 . The insert of  claim 1 , wherein the at least one wall comprises four walls, at least one of the walls sloping inwards from the first opening to the second opening. 
     
     
         3 . The insert of  claim 2 , further comprising a cap extending between the four walls at the second end, the second opening being located in the cap. 
     
     
         4 . The insert of  claim 1 , wherein the at least one wall comprises four walls sloping inwards from the first opening to the second opening. 
     
     
         5 . The insert of  claim 1 , wherein the at least one wall comprises a continuous frustoconical wall. 
     
     
         6 . The insert of  claim 1 , wherein the second opening is dimensioned to match an air outlet in the air handler. 
     
     
         7 . The insert of  claim 1 , wherein the second end has a third opening therein for permitting the conditioned air to exit the insert, and the at least one wall defines the first air passage and a second air passage tapering from the first opening to the second opening. 
     
     
         8 . An air handler, comprising:
 a housing;   an air conditioning element disposed in an air passage in the housing through which air is moved by a fan;   a first air outlet in the housing; and   at least one wall of the air passage within the housing tapering the air passage from between the air conditioning element and the first air outlet.   
     
     
         9 . The air handler of  claim 8 , wherein the at least one wall comprises four walls, at least one of the walls sloping inwards from the air conditioning element to the first air outlet. 
     
     
         10 . The air handler of  claim 8 , wherein the at least one wall comprises four walls sloping inwards from the air conditioning element to the first air outlet. 
     
     
         11 . The air handler of  claim 8 , wherein the at least one wall comprises a continuous frustoconical wall. 
     
     
         12 . The air handler of  claim 8 , wherein the air conditioning element is a heat exchanger coil. 
     
     
         13 . An air handler, comprising:
 a housing;   an air conditioning element disposed in an air passage in the housing through which air is moved by a fan;   a first air outlet in the housing;   a second air outlet in the housing; and   at least one wall of the air passage within the housing tapering the air passage from between the air conditioning element and the first and second air outlets.
