Abstract

A modular Electronically-Controlled Register Vent (ECRV) that can be easily installed by a homeowner or general handyman is disclosed. The ECRV can be used to convert a non-zoned HVAC system into a zoned system. The ECRV can also be used in connection with a conventional zoned HVAC system to provide additional control and additional zones not provided by the conventional zoned HVAC system. In one embodiment, the modular ECRV can be configured to various sizes and form-factors that conform to a standard manually-controlled register vent. In one embodiment, a zone thermostat is configured to provide thermostat information to the ECRV. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones and provides heating and cooling to the various zones according to a cost budget.

Claims

1. An electronically-controlled register vent for providing zoned heating and cooling, comprising:

a first register vent portion comprising a first fixed member and a first movable member wherein said first register vent portion is substantially closed when said first movable member is in a first position relative to said first fixed member and said first register vent portion is substantially open when said first movable member is in a second position relative to said first fixed member;

a second register vent portion comprising a second fixed member and a second movable member, said first fixed portion and said second fixed member configured to be connected to form a register vent assembly;

a controller;

a mechanical actuator provided to said controller, said mechanical actuator configured to move said first movable member and said second moveable member;

a wireless communication system provided to said controller;

a temperature sensor provided to said controller, said temperature sensor configured to measure a temperature of air inside a duct; and

a power source provided to said controller, said controller configured to control said actuator in response to a wireless communication received from a zone thermostat.

2. The electronically-controlled register vent of claim 1, further comprising an airflow sensor.

3. The electronically-controlled register vent of claim 1, further comprising a differential pressure sensor.

4. The electronically-controlled register vent of claim 1, further comprising an air velocity sensor.

5. The electronically-controlled register vent of claim 1, further comprising an auxiliary power source.

6. The electronically-controlled register vent of claim 1, further comprising a humidity sensor.

7. The electronically-controlled register vent of claim 1, further comprising a fan.

8. The electronically-controlled register vent of claim 1, wherein said controller is configured to transmit sensor data according to a threshold test.

9. The electronically-controlled register vent of claim 8, wherein said threshold test comprises a high threshold level.

10. The electronically-controlled register vent of claim 8, wherein said threshold test comprises a low threshold level.

11. The electronically-controlled register vent of claim 8, wherein said threshold test comprises an inner threshold range.

12. The electronically-controlled register vent of claim 8, wherein said threshold test comprises an outer threshold range.

13. The electronically-controlled register vent of claim 1, wherein controller is configured to receive an instruction to change a status reporting interval.

14. The electronically-controlled register vent of claim 1, wherein controller is configured to receive an instruction to change a sensor data reporting interval.

15. The electronically-controlled register vent of claim 1, wherein said zone thermostat is configured to monitor a status of one or more electronically-controlled register vents.

16. The electronically-controlled register vent of claim 1, wherein said actuator is configured to provide position feedback to said controller.

17. The electronically-controlled register vent of claim 1, wherein said wireless communication system communicates using radio-frequency communication.

18. The electronically-controlled register vent of claim 1, further comprising a visual indicator to indicate a low-power condition when said power source is low.

19. The electronically-controlled register vent of claim 1, said controller configured to use a predictive model to compute a control program for said actuator.

20. The electronically-controlled register vent of claim 26, said control program configured to reduce power consumption by said actuator.

21. The electronically-controlled register vent of claim 26, said control program configured to reduce movement of said actuator.

22. The electronically-controlled register vent of claim 1, said zone thermostat configured to use a predictive model to compute a control program for said actuator.
