Abstract
A portable self contained air conditioner which has a platform base (20) with an enclosure (22) attached on top. A recropricating engine (38) is resiliently mounted on the platform with a propeller fan (44) on the front drive and a blower (46) directly attached to the flywheel on the back. A refrigerant compressor (54) is also directly coupled to the engine flywheel with a universal joint drive shaft (56). A drive shaft adapter (60) registers to the flywheel on one end and to the drive shaft on the other with the blower impeller (50) sandwiched in between. A vapor cycle refrigerant system provides the cooling effect and an electrical control system furnishes the operational direction. The engine cooling is integral with the refrigeration system utilizing an additional section of the condenser coil (66) and the same air movement supplied by the propeller fan on the engine. The preferred embodiment includes a pair of closely spaced tandem wheels on each side and the internal component location allows a balanced center of gravity for portability. The blower employs a circular outlet at right angles to the plane of the impeller directing the pressurized air to exit at 90 degrees to the plane of the blower. Optional heating is supplied by a hydraulic system in conjunction with jacket water from the engine heating the conditioned air stream.
