Abstract

A system includes a generator and an enclosure surrounding the generator, the generator having an air intake and an inside surface. The system also includes an air intake housing affixed to the inside surface of the enclosure and fluidly connected to the air intake, the air intake housing terminating in an air intake housing inner plate positioned at inner edge of the air intake housing. The air intake housing inner plate has a plurality of air intake holes. In addition, the system includes a damper, the damper abutting the air intake housing inner plate, the damper having a plurality of damper holes. The damper is adapted to slide along the air intake housing inner plate.

First claim

The invention claimed is:

1. A system comprising:
a generator;
an enclosure surrounding the generator, the generator having an air intake, an inside surface, and an outside surface;
an air intake housing affixed to the inside surface of the enclosure and fluidly connected to the air intake, the air intake housing terminating in an air intake housing inner plate positioned at an inner edge of the air intake housing, the air intake housing inner plate having a plurality of air intake holes; and
a damper, the damper abutting the air intake housing inner plate, the damper having a plurality of damper holes, the damper adapted to slide along the air intake housing inner plate.

2. The system of claim 1 , wherein the enclosure completely encloses the generator.

3. The system of claim 1 , wherein the air intakes comprises holes in the sides or top of the enclosure.

4. The system of claim 1 , wherein the air intake housing is composed of steel or aluminum.

5. The system of claim 1 , wherein a filter is positioned within the air intake housing.

6. The system of claim 1 , wherein the air intake holes are drilled, punched or formed.

7. The system of claim 1 , wherein the damper is a plate.

8. The system of claim 1 , wherein when the damper slides along the air intake housing inner plate at least some of the air intake holes and damper holes align.

9. The system of claim 1 , wherein the damper is held by rails.

10. The system of claim 1 further comprising exterior louvers, the exterior louvers positioned opposite the damper within the air intake housing.

11. The system of claim 10 , wherein the exterior louvers may be locked in an open position or in a closed position.

12. The system of claim 1 further comprising:
an air intake control system;
an interior temperature sensor positioned within the enclosure and electrically connected to the air intake control system; and
an exterior temperature sensor positioned outside the enclosure and electrically connected to the air intake control system.

13. The system of claim 12 , wherein the system further comprises a generator air feed temperature sensor positioned adjacent the generator.

14. The system of claim 12 further comprising exterior louvers, the exterior louvers positioned opposite the damper within the air intake housing.

15. A method comprising:
supplying an air intake control system;
electrically connecting an exterior temperature sensor to the air intake control system, the exterior temperature sensor positioned outside an enclosure, wherein a generator is positioned within the enclosure;
electrically connecting an interior temperature sensor to the air intake control system, the interior temperature sensor positioned within the enclosure;
electrically connecting a mechanical electric actuator to the air intake control system; and
mechanically connecting the mechanical electric actuator to a damper, the damper having damper holes, the damper abutting an air intake housing inner plate, the air intake housing inner plate having air intake holes.

16. The method of claim 15 further comprising:
detecting an outside temperature using the exterior temperature sensors;
detecting an inside temperature using the interior temperature sensors;
determining a desired generator air feed temperature;
sliding the damper to align the damper holes with the air intake holes until the desired generator air feed temperature is achieved.

17. The method of claim 16 , wherein the generator air feed temperature is measured by a generator air feed temperature sensor.

18. The method of claim 16 , wherein the damper is aligned using the mechanical electric actuator.

19. The method of claim 16 , wherein the damper is aligned to a closed position, an open position, or a partially open position.

20. The method of claim 15 , further comprising:
supplying exterior louvers, the exterior louvers positioned opposite the damper within the air intake housing;
detecting an outside temperature using the exterior temperature sensors;

detecting an inside temperature using the interior temperature sensors;
determining a desired generator air feed temperature;
opening or closing the exterior louvers to achieve the desired generator air feed temperature.
