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.

An air conditioning unit comprising a cabinet with an assemblage of mechanical refrigeration system components mounted in an operable array in said cabinet and including a condenser coil disposed in a condenser coil compartment with said cabinet, said cabinet comprising a base pan having said components mounted thereon and a removable shroud mounted over said base pan to cover said components, wherein the improvement comprises said base pan having a bottom wall and an upstanding perimeter wall connected to said bottom wall having at its upper edge an outwardly protruding porch flange to provide an overhang ledge extending at least partially along the perimeter of said base pan, said ledge having air inlet and outlet means therein providing air flow communication between ambient air exteriorly of said cabinet and said interior condenser coil compartment of said unit. An air conditioning unit adapted for roof mounting on a recreational vehicle or the like and presenting an overall low profile appearance thereon comprising a cabinet having a base pan and a cover with an assemblage of mechanical refrigeration system components mounted in an operable array in said cabinet on said base pan, said cabinet being generally rectangular in plan view with its front and rear ends forming the narrower ends thereof and adapted to be juxtaposed respectively to the front and rear ends of the vehicle, said cabinet having bulkhead means therein sub-dividing the interior of said cabinet into at least an evaporator coil compartment at the interior front of said cabinet and a condenser coil compartment extending from said evaporator coil compartment to the interior rear of said cabinet, wherein the improvement comprises having said components include first and second low profile centrifugal blowers disposed respectively in said evaporator and condenser compartments for inducing air flow respectively therethrough and oriented with their rotational axes extending front to rear in said cabinet, an electric motor coaxially disposed between said blowers and having a drive shaft on which said blowers are fixedly drivingly mounted for direct rotation therewith for concurrent operation thereof, and a rotary hermetic compressor disposed in a cylindrical casing and oriented with its longitudinal axis generally horizontal generally parallel to said blower axes and with its maximum vertical dimension below that of said blowers to thereby reduce the overall vertical dimension of said unit components to provide a low profile cabinet.
