ABSTRACT:
A temporary air conditioning condensing fan is mounted in a rigid housing which may be easily and rapidly mounted at the air exhaust side of an air conditioning unit to provide a temporary flow of cooling air to the condenser, in the event the existing condensing fan fails. A portion of the housing forms a shroud around the temporary condensing fan and directs the flow of air over the condenser. A head pressure adjusting valve adapts the temporary condensing fan to differently sized air conditioning units and maintains an efficient head pressure on the condenser of the existing air conditioning unit.
