Abstract

A method is disclosed for generating and distributing electric power for localized use. The method entails providing an enclosed building having an air conditioning and ventilation unit for supplying cooled air within the building, the unit including a closed loop circuit configured to operate a closed loop refrigeration cycle, including a compressor operable to compress a working fluid of the closed loop circuit. The method further includes engaging an internal combustion engine with the compressor and operating the internal combustion engine to drive the compressor, thereby transferring energy to the refrigeration cycle. The method may also involve engaging an electric motor with the compressor and operating the electric motor to drive the compressor, thereby transferring energy to the refrigeration cycle.

Claims

1. A method of generating and distributing electric power to meet localized demand, said method comprising:

providing a local environment having an air conditioning unit for supplying cooled air within the local environment, the unit including a loop circuit configured to operate a loop refrigeration cycle, including a compressor operable to compress a working fluid of the closed loop circuit;

engaging an internal combustion engine with the compressor;

operating the internal combustion engine to drive the compressor, thereby transferring energy to the refrigeration cycle;

engaging an electric motor generator unit with the compressor; and

operating the electric motor generator unit to drive the compressor, thereby transferring energy to the refrigeration cycle.

2. The method of claim 1, further comprising:

before engaging the electric motor generator unit, disengaging the internal combustion engine from the compressor.

3. The method of claim 1, further comprising:

selectively engaging one of the internal combustion engine and electric motor generator unit to drive the compressor.

4. The method of claim 1, wherein operating the internal combustion engine generates heat, the method further comprising:

communicating heat generated by the internal combustion engine to the local environment.

5. The method of claim 4, wherein communicating heat includes transferring heat to preheat water of a hot water heater.

6. The method of claim 4, wherein communicating heat includes transferring heat to a water supply.

7. The method of claim 4, wherein communicating heat includes transferring heat to circulating air circulated for space heating in the local environment.

8. The method of claim 1, wherein the local environment is provided by a building.

9. The method of claim 1, wherein operating the electric motor generator unit includes operating the motor generator unit with DC power supplied by a battery bank in the localized environment.
