Abstract: Apparatus for distributing condensate over an outdoor heat exchanger of an air conditioner unit wherein the outdoor heat exchanger and an outdoor fan are enclosed within a housing. An orifice is located in the bottom of the housing adjacent to the fan and condensate produced in the unit is brought to the entrance of the orifice. The orifice is connected to a reservoir that directs condensate passing through the orifice to a point beneath the outdoor fan where the condensate can be picked by the fan and distributed over the heat exchanger surfaces. The size and shape of the orifice is matched to the pressure differential produced over the fan so that condensate is drawn rapidly into the housing and distributed by the fan over the outdoor heat exchanger.

Abstract: A refrigerated showcase has a front opening through which a consumer can view and access foodstuffs on display.

Abstract: A rotating shroud is located on the suction side of the tips of a propeller fan and coacts with an inlet orifice to provide the physical separation between suction and discharge when the unit is in operation. The pressure differential across the fan tends to cause the condensate to move towards the suction side and into the path of the slinger (rotating shroud).
