Package terminal/split unit air conditioning

Abstract

A system and method for a package terminal/split unit air conditioning unit which eliminates condensate leakage normally associated with air conditioning systems. The present invention includes a first section and a second section, where the first section connects to the second section by means of refrigeration piping, drain piping and electrical wiring and the first section includes a blower chamber and a condensing chamber. The air conditioning unit may operate with the two sections joined together or separated. During operation, the second section generates and collects condensate in a drain pan, the accumulated condensate flows, via drain piping, into a centrifugal blower within the first section. The centrifugal fan blower conveys the condensate into the condensing chamber. The heat within the condensing chamber causes the condensate to evaporate, and therefore eliminates leakage of condensate from the second section.

What is claimed is:  
     
         1 . An air conditioning unit comprising: 
 a first section which includes a blower chamber and a condensing chamber separated by a barrier, wherein the blower chamber includes a first centrifugal blower and a first motor, and the condensing chamber includes a compressor, a condensing coil, and drain piping; and    a second section which includes an expansion coil, a drain pan, a second centrifugal blower, a second motor, and drain piping, wherein the second section connects to the first section, and wherein the second section generates and collects condensate in the drain pan, the condensate flows into the first centrifugal blower via the drain piping, and the first centrifugal blower conveys the condensate through an opening in the barrier and into the condensing chamber.    
     
     
         2 . An air conditioning unit according to  claim 1 , wherein the second section is housed in a galvanized steel cabinet.  
     
     
         3 . An air conditioning unit according to  claim 1 , wherein the expansion coil includes aluminum fins bonded to copper tubes.  
     
     
         4 . An air conditioning unit according to  claim 1 , wherein a liquid refrigerant is supplied through the expansion coil.  
     
     
         5 . An air conditioning unit according to  claim 1 , wherein the second motor is a low temperature pole motor.  
     
     
         6 . An air conditioning unit according to  claim 1 , wherein the first motor is a pole fan motor.  
     
     
         7 . An air conditioning unit according to  claim 1 , wherein the first centrifugal blower is surrounded by an enclosure.  
     
     
         8 . An air conditioning unit according to  claim 8 , wherein the enclosure is made of galvanized steel.  
     
     
         9 . An air conditioning unit according to  claim 1 , wherein the condensing coil includes aluminum fins bonded to copper tubes.  
     
     
         10 . An air conditioning unit according to  claim 1 , wherein the barrier is a galvanized sheet metal.  
     
     
         11 . A method of eliminating condensate in an air conditioning unit, comprising of the following steps: 
 collecting condensate in a storage device, wherein the air conditioning unit creates condensate during the operation of the air conditioning unit;    transferring the condensate from the storage device to a centrifugal blower; and    dispersing the condensate into a condensing chamber, wherein the condensate evaporates due to heat within the condensing chamber.    
     
     
         12 . A method according to  claim 11 , wherein the storage device is a drain pan.
