Abstract

Thermostatic HVAC and other energy management controls that are connected to a computer network. For instance, remotely managed load switches incorporating thermostatic controllers inform an energy management system, to provide enhanced efficiency, and to verify demand response with plug-in air conditioners and heaters. At least one load control device at a first location comprises a temperature sensor and a microprocessor. The load control device is configured to connect or disconnect electrical power to the an attached air conditioner or heater, and the microprocessor is configured to communicate over a network. In addition, the load control device is physically separate from an air conditioner or heater but located inside the space conditioned by the air conditioner or heater.

Claims

1. An apparatus for controlling a window-mounted air conditioner comprising:

a load control device comprising at least one microprocessor configured to control the connection or disconnection of electric power to said air conditioner, said at least one microprocessor further configured to obtain temperature measurements and communicate over a network;

a remote server capable of sending messages to and receiving messages from said load control device, and capable of receiving messages from a utility to reduce electricity demand;

wherein said messages sent from said load control device to said remote server comprise said temperature measurements;

wherein said messages sent from said remote server to said load control device comprise commands to disconnect electric power from said window-mounted air conditioner; and

wherein said load control device is plugged into an electric outlet within the space controlled by said air conditioner.

2. The system of claim 1 wherein the load control device comprises a user interface.

3. The system of claim 1 wherein the at least one microprocessor is configured to generate the operational control instructions based at least in part on the temperature measurements associated with the space conditioned by the plug-in air conditioner and based at least in part on the measurements of outside temperatures from at least one other source.

4. The system of claim 1 in which the plug-in air conditioner is mounted through an opening in a building envelope.

5. The system of claim 1 in which a mobile device comprises a user interface.

6. The system of claim 1 in which the remote server records data generated by the load control device.

7. The system of claim 1 in which the load control device further measures at least one of the group consisting of the electrical current, and voltage passing through the load control device.

8. The system of claim 1 in which the load control obtains sensor information regarding occupancy of the space conditioned by the plug-in air conditioner or plug-in portable heater.

9. The system of claim 1 in which the load control device is paired with a mobile device.

10. The system of claim 1 wherein the at least one microprocessor is configured to generate the operational control instructions based at least in part on the location of a mobile device.

11. A method for controlling a window-mounted air conditioner comprising:

connecting at a first location a load control device comprising at least one microprocessor that is configured to control the connection or disconnection of electric power to said air conditioner, wherein said at least one microprocessor is further configured to obtain temperature measurements and communicate over a network;

connecting the load control device to a remote server capable of sending messages to and receiving messages from said load control device, and capable of receiving messages from a utility to reduce electricity demand;

transmitting from said load control device to said remote server messages comprising said temperature measurements;

transmitting from said remote server to said load control device messages comprising commands to disconnect electric power from said window-mounted air conditioner; and

wherein said load control device is plugged into an electric outlet within the space controlled by said air conditioner.

12. The method of claim 11 further comprising displaying a user interface on the load control device.

13. The method of claim 11 wherein the operational control instructions received from the one or more processors are based at least in part on the temperature measurements associated with the space conditioned by the plug-in air conditioner and are based at least in part on the measurements of outside temperatures from at least one other source.

14. The method of claim 11 in which the plug-in air conditioner is mounted through an opening in a building envelope.

15. The method of claim 11 in which a mobile device comprises a user interface.

16. The method of claim 11 in which the remote server records data generated by the load control device.

17. The method of claim 11 in which the load control device further measures at least one of the group consisting of the electrical current, and voltage passing through the load control device.

18. The method of claim 11 in which the load control obtains sensor information regarding occupancy of the space conditioned by the plug-in air conditioner or plug-in portable heater.

19. The method of claim 11 further comprising pairing the load control device with a mobile device.

20. The method of claim 11 further comprising generating the operational control instructions based at least in part on the location of a mobile device.
