Abstract
A compressor system for a vehicle comprising a vehicle internal combustion engine and a vehicle heating and cooling system. The compressor system comprising a compressor/motor generator defining a compressor motor/generator shaft, a compressor mechanically connected to the compressor motor/generator shaft; and a engine clutch mechanically connected to the compressor motor/generator shaft and to the vehicle internal combustion engine.
Claims4
A heat pump method for a vehicle comprising a vehicle internal combustion engine, a vehicle heating and cooling system, and a DC bus, the method comprising the steps of:
- providing a compressor motor/generator defining a compressor motor/generator shaft;
- mechanically connecting a compressor to the compressor motor/generator shaft;
- mechanically connecting an engine clutch to the compressor motor/generator shaft and to the vehicle internal combustion engine;
- operatively connecting the compressor to a condenser coil, an expansion valve, and an evaporator coil to form the heat pump system;
- causing the vehicle internal combustion engine to operate the compressor motor/generator such that the compressor motor/generator applies power to the DC bus when the engine clutch operatively connects the compressor motor/generator shaft to the vehicle internal combustion engine;
- and
- causing the compressor motor/generator to operate the compressor based on power from the DC bus when the engine clutch disconnects the compressor motor/generator shaft from the vehicle internal combustion engine.
