ABSTRACT:
A self-contained, self-propelled air-conditioning system is provided for supplying air to structures, such as aircraft on the ground at airports. The aircraft are of the type having an inlet duct for conveying the air through the structure. The system includes a suitable truck having a frame or chassis mounted on wheels. The system also includes a diesel engine separate from the engine of the truck mounted on the chassis for supplying mechanical energy and an electrical generator mechanically connected to the diesel engine for changing the mechanical energy into electrical energy. A ventilation system is mounted on the frame and is electrically connected to the generator for moving air from the ambience to the inlet duct. A pair of independent refrigeration systems, each including a compressor, are mounted on the frame. The compressors are electrically connected to the generator. Each refrigeration system cools the moving air independently from the other refrigeration system. The air-conditioning system further includes an electrical control system including a plug adapted for connection with an external power supply. The plug allows the air-conditioning system to be electrically connected to the external power supply.
