Abstract

A self contained, mechanical cooling apparatus is mountable on a door which is pivoted on hinges to a door frame. The door may be mounted for either exterior or interior service in a residential or commercial setting. The door frame is attached to the building structure in a conventional manner. The door provides a closure for a designated room and the door mounted cooling apparatus maintains the desired, generally lower, temperature in the room. Major cooling components mounted in the door include a refrigerant compressor, evaporator coil, condenser coil, accumulator, capillary tubing, refrigerant piping and electrical components. The parts are enclosed in a one piece, premolded plastic apparatus housing. Two supply air fans are mounted within the housing, and molded in supply and return air grilles communicate with the enclosed space. Two condenser air fans are mounted within the housing and circulate air to and from the condenser coil through a multidirectional air louver mounted on the exterior surface of the doors.
