Portable integrated power supply and HVAC unit
View Patent ↗An integrated portable power unit including a power pack and a generator mounted within a first compartment and including a second isolated air handling compartment. The air handling compartment may include a fan for moving air through ductwork, a radiator for receiving heated cooling water from the power pack and a heat exchanger connected to a compressor for generating cooled water, the compressor and the fan connected to the power pack.
1. An integrated power unit comprising:
a base having a generation side and an air handling side, the generation side isolated from the air handling side to prevent air from one side entering the other side;
the generation side having an electrical generator driven by an engine;
the electrical generator having at least one electrical power outlet providing electrical power therefrom;
the air handling side having an air handling compartment; and
an air handler mounted within the air handling compartment, the air handler including an air blower for moving air through the air handling compartment.
2. The integrated power unit of claim 1 , wherein ductwork is mounted inside the air handling compartment.
3. The integrated power unit of claim 2 , wherein the air blower is a fan is mounted within the ductwork.
4. The integrated power unit of claim 3 , wherein the fan generates greater than atmospheric pressure within the ductwork when the fan is operating.
5. The integrated power unit of claim 1 , wherein the engine is connected to the electrical generator by a shaft.
6. The integrated power unit of claim 1 , wherein the air blower is driven by the engine.
7. The integrated power unit of claim 1 , wherein the air blower is driven by a hydraulic pump driven by the engine.
8. The integrated power unit of claim 1 , wherein the air blower is driven by an electric motor connected to the electrical generator.
9. The integrated power unit of claim 1 , wherein an engine radiator is mounted on the engine side and an air handler radiator is mounted in the air handling compartment.
10. The integrated power unit of claim 9 , wherein cooling water may be selectively directed between the engine radiator and the air handler radiator using a proportioning valve.
11. The integrated power unit of claim 1 , further comprising a compressor driven by the engine, the compressor connected to a heat exchanger mounted within the air handler compartment near the air blower so that air flowing through the air handler compartment passes through the heat exchanger before exiting the air handler compartment.
12. The integrated power unit of claim 11 , wherein the compressor is connected to the engine by a clutch belt drive.
13. The integrated power unit of claim 1 , wherein the air handling compartment includes an inlet at a first end of the air handling compartment and an outlet at a second end of the air handling compartment.
14. The integrated power unit of claim 1 wherein the air handling compartment includes at least one air filter to filter air flowing through the air handler.
15. The integrated power unit of claim 1 , wherein the base is removably mounted to a wheeled trailer.
16. The integrated power unit of claim 1 further including a unit controller mounted to the base, the unit controller controlling operation of the portable integrated power unit.
17. The integrated power unit of claim 1 , wherein the electrical generator may be selectively decoupled from the engine.
18. The integrated power unit of claim 1 , wherein a heating element is mounted in the air handling compartment.
19. The integrated power unit of claim 1 , wherein an air return duct may be attached to the inlet.
