ABSTRACT:
A housing for physically and thermally isolating the evaporator section of an air conditioning unit that is mounted on the cabin roof of a trailer, van, or motor home. The housing is molded in two sections with the lower section being secured to the base pan of the unit over return air duct and the supply air duct formed in the pan. The housing is divided into a blower chamber containing the supply air duct and an evaporator coil chamber containing the return air duct. A converging nozzle is molded integrally into the housing which connects the evaporator coil chamber with the blower chamber. Elongated vertically disposed openings are provided in the side walls of the housing having guideways for contacting the tube sheets of an evaporator coil that is mounted in the evaporator coil chamber to prevent air from passing around said coil. Internal surfaces are provided within the housing for efficiently turning the air flow through the housing 180.degree..
