The Patent Description & Claims data below is from USPTO Patent Application 20060151165, Proportional control system for a motor.

1. A proportional control system for use in an HVAC unit within a ventilation system comprising: a) a processing means programmed with an air exchange-defrost cycle; b) one or more motor speed sensing means positioned in the HVAC unit and operatively connected to the processing means; and c) one or more temperature sensing means positioned in the HVAC unit and operatively connected to the processing means wherein the temperature and motor speed sensors determine the motor speed to be applied during the defrost cycle.

2. The proportional control system of claim 1 wherein a first temperature sensing means is positioned the fresh air inlet intake of the HVAC unit.

3. The proportional control system of claim 1 wherein a first speed sensing means is positioned on the fresh air intake impeller.

4. The proportional control system of claim 1 wherein a second sensing means is positioned in the stale air intake of the HVAC unit.

5. The proportional control system of claim 1 wherein a damper mechanism is installed in the air inlet intake of an HVAC unit.

6. A proportional control system for use in an HVAC unit within a ventilation system comprising: a) a processing means programmed with an air exchange-defrost cycle; b) one or more sensing means positioned in the HVAC unit and operatively connected to the processing means; and c) a damper mechanism positioned in the HVAC unit; wherein the temperature sensing means determine the motor speed to be applied during the defrost cycle.

7. The proportional control system of claim 6 wherein a first temperature sensing means is positioned in the air inlet intake of the HVAC unit.

8. The proportional control system of claim 6 wherein a motor speed sensor is incorporated within the processing means.

9. The proportional control system of claim 6 wherein a damper mechanism is installed in the air inlet intake of an HVAC unit.
