Abstract

A high-efficiency HVAC system and method of operation, for use in a house or building, having a plurality of components, including flexible, plastic duct tubing forming supply pipes that connect an air handler and a plurality of zones to deliver supply air to the zones and return pipes that connect the air handler and the zones to re-circulate return air; the air handler having a fan assembly powered by a variable blower motor to blow supply air to the zones; a heat pump having a variable compressor powered by a variable compressor motor to direct a working fluid to and from the air handler and a variable fan motor that rotates a fan blade within the heat pump; and a circuit control system for adjusting the variable compressor motor and the variable fan motor in the heat pump and the variable blower motor in the air handler.

Claims

1. A high-efficiency HVAC system for use in a house or building, having a plurality of components comprising:

flexible, plastic duct tubing forming supply pipes that connect an air handler and a plurality of zones to deliver supply air to the zones in the house or building and return pipes that connect the air handler and the plurality of zones to re-circulate return air from the zones to the air handler;

the air handler having a fan assembly powered by a variable blower motor to blow supply air through the supply pipes to the plurality of zones to individually control air humidity, air purity and air temperature within the zones in the building or house;

a heat pump having a variable compressor powered by a variable compressor motor to direct a working fluid to and from the air handler and a variable fan motor that rotates a fan blade within the heat pump; and

a circuit control system for adjusting the variable compressor motor and the variable fan motor in the heat pump and the variable blower motor in the air handler in response to the capacity required by the HVAC system.

2. The high-efficiency HVAC system of claim 1 further including separate controls in each zone communicating with a wireless control within the air handler to send a programmed amount of supply air to each zone as determined by the controls in each zone.

3. The high-efficiency HVAC system of claim 1 wherein the plurality of components of the HVAC system are pre-assembled and factory-tested and require much less time to install as compared to the typical HVAC system.

4. The high-efficiency HVAC system of claim 1 wherein the working fluid directed by the heat pump to the air handler is selected from the group comprising a refrigerant and a coolant.

5. The high-efficiency HVAC system of claim 4 wherein the heat pump includes;

a variable fan motor that rotates the fan blade and an alternator with a shaft; and

the variable compressor connected to two lines between the heat pump and the air handler and powered by the variable compressor motor.

6. The high-efficiency HVAC system of claim 5 further including solar panels to power components of the HVAC system including the variable fan motor, the variable compressor motor, and the variable blower motor.

7. The high-efficiency HVAC system of claim 5 further including turning the alternator with the fan blade using wind energy.

8. The high-efficiency HVAC system of claim 1 further wherein the air handler 14 includes:

an electronic air cleaner which removes contaminants from the re-circulated air which enters the air handler;

a UV Germicidal Lamp which kills potentially harmful microorganisms before the supply air is dispersed throughout the zones; and

a multiple zone pneumatic control which operates a plurality of damper valves, each located within supply pipes from the air handler to each zone to vary the amount of supply air going into each zone.

9. The high-efficiency HVAC system of claim 8 further including an electric heater disposed within the air handler to provide extra heat to raise the temperature of the supply air before it is dispersed through the supply pipes to the various zones.

10. The high-efficiency HVAC system of claim 8 further including a supplemental hot water storage tank for distributing hot water to a coil disposed within the air handler to provide extra heat to raise the temperature of the supply air before it is dispersed through the supply pipes to the various zones.

11. A method of operating a high-efficiency HVAC system for use in house or building, having a plurality of components comprising:

delivering supply air to a plurality of zones in the house or building from an air handler through flexible, plastic duct tubing;

15. The method of claim 14, further including powering components of the HVAC system from the group comprising the variable fan motor the variable compressor motor, and the variable motor blower with solar panels.

16. The method of claim 14, further including turning the alternator with the fan blade using wind energy.

17. The method of claim 14, further including:

removing contaminants from the re-circulated air which enters the air handler;

killing potentially harmful microorganisms before the supply air is dispersed throughout the zones with a UV Germicidal Lamp; and

operating a plurality of damper valves, each located within supply pipes from the air handler to each zone to vary the amount of supply air going into each zone with a multiple zone pneumatic control.

18. The method of claim 17, further including distributing hot water to a coil disposed within the air handler to provide extra heat to raise the temperature of the supply air before it is dispersed through the supply pipes to the various zones.

19. A high-efficiency HVAC system kit for use in house or building, having a plurality of components comprising:
