Abstract
Abstract An air conditioning apparatus having an evaporator for conditioning air flowed in heat exchange relationship therewith. The evaporator is cooled by refrigerant fluid delivered thereto through an expansion means from a supply duct leading from a condenser of the refrigeration system. The refrigerant in the supply duct is supercooled by means of heat exchange relationship thereof, with condensate resulting from the condensation of the moisture in the air being conditioned by the evaporator being collected in a suitable receiver. The heat exchange relationship of the refrigerant to the condensate is such that the condensate is heated to vaporization for improved heat withdrawal from the refrigerant.

Claim 1
Independent Claim
155 words
In an air conditioning system having an evaporator disposed in an evaporator space for conditioning moist warm air flowed in heat exchange relationship therewith, a condenser, and means for conducting condensed refrigerant fluid from said condenser to said evaporator for cooling the evaporator to absorb heat from said flowed air, means for cooling the conducted refrigerant for improved heat absorption efficiency in said evaporator comprising: container means subjacent said evaporator defining a space opening to the evaporator space for collecting condensate moisture condensed from the warm air as a result of the heat exchange with said evaporator; means for disposing the refrigerant fluid conducting means in heat exchange relationship with the collected condensate in said container means for transferring sufficient heat from the refrigerant fluid to the collected condensate to effect vaporization of the condensate; and fluid transfer means independent of said condenser for removing vaporized condensate to a discharge zone remote from the evaporator.
