Abstract: Apparatus for and a method of preventing the formation of moisture on the exterior of an air conditioning unit. Condensate collected at the evaporator and discharged into the condenser section of the unit absorbs heat energy eliminating cold spots on the exterior surface of the unit where moisture may condense. A condensate collection pan having various flow barriers is utilized to route the cold condensate from the evaporator along a tortuous path in heat exchange relationship with ambient air. Heat energy is transferred from the ambient air to the condensate in the condensate collection pan thereby acting to increase the temperature of the condensate prior to it being discharged into the condenser section.

Abstract: Apparatus forming a self-contained air conditioning unit which includes parts and subassemblies of a particular configuration that may be united with each other in order to construct the apparatus with a minimum of cost and effort.
