Roof mount air conditioner

摘要

A roof mounted air conditioning unit for recreation vehicles comprising a cabinet made up of a base pan and a removable shroud. The base pan has a bottom wall and an upstanding perimeter wall with an outwardly protruding porch flange extending around the entire upper edge of the perimeter wall to provide stiffening reinforcement and a ledge on which the shroud seats. The ledge has air inlets and outlets therein providing air flow communication between ambient air and the condenser compartment. The perimeter wall also has air inlets and outlets therein. The shroud is generally imperforate and serves as a roof-like cover for the base pan. The shroud has a generally light color and the base pan has a generally dark color such that the air inlets and outlets in the pan perimeter wall are camouflaged from view. The cabinet is sub-divided by bulkheads into junction compartments including an evaporator coil compartment and the condenser coil compartment. Evaporator and condenser centrifugal blowers are disposed respectively in the evaporator and condenser compartments for inducing air flow respectively therethrough. An electric motor is coaxially disposed between the blowers and has a drive shaft coupled thereto for concurrent operation thereof. A rotary hermetic compressor is disposed in a cylindrical case and oriented with its longitudinal axis generally horizontal to thereby cooperate with the blowers in reducing the overall vertical dimension of the system components to provide a low profile cabinet.
