Abstract
The heating and cooling of structures is accomplished by driving a compressor of an air conditioning system with an internal combustion engine. The engine also drives an electrical generator to provide electrical power to the various components of the heating and cooling subsystem such as fans, motors, pumps, and controls. A constantly variable transmission apparatus and a differential power transmission are cooperatively connected to the engine to provide substantially constant speed operation of the generator.
