Abstract

A method of providing ventilation for an enclosed space includes detecting, by a controller including one or more processing devices, an operation of a door to the enclosed space in response to receiving a first signal indicative of an electrical characteristic of a motor that operates the door to the enclosed space. The method further includes generating, by the controller responsive to detecting the operation of the door, a control signal configured to operate a ventilation system to exhaust air from within the enclosed space to an environment outside of the enclosed space. The method also includes transmitting the control signal to cause an activation of the ventilation system.

Claims

1. A method of providing ventilation for an enclosed space, the method comprising:

receiving by a controller a first signal indicative of an electrical characteristic of a motor, the electrical characteristic being sensed during an operation of the motor;

determining based on the first signal, by the controller including one or more processing devices, that a door to the enclosed space is in a process of opening or closing, wherein the door to the enclosed space is driven by the motor;

generating, by the controller responsive to determining that the door to the enclosed space is in the process of opening or closing, a control signal configured to operate a ventilation system to exhaust air from within the enclosed space to an environment outside of the enclosed space;

transmitting the control signal to the ventilation system; and

activating the ventilation system based on the control signal.

2. The method of claim 1, wherein the enclosed space is a garage.

3. The method of claim 1, wherein the electrical characteristic is selected from the group consisting of a current, a voltage, a power, and a frequency of the motor.

4. The method of claim 1, wherein the first signal is indicative of opening of the door.

5. The method of claim 4, further comprising:

receiving a second signal indicative of closing of the door during an operation of the ventilation system; and

responsive to receiving the second signal, deactivating the ventilation system after a duration of time.

6. The method of claim 5, further comprising receiving a user input indicative of the duration of time.

7. The method of claim 1, further comprising:

receiving a second signal indicative of a temperature within the enclosed space; and

determining, based on the second signal, that the temperature is above a threshold; and

responsive to determining that the temperature is above the threshold, operating the ventilation system to exhaust air from within the enclosed space to the environment.

8. The method of claim 7, further comprising:

determining that the temperature is at or below the threshold; and

deactivating, responsive to determining that the temperature is at or below the threshold, the ventilation system.

9. The method of claim 1, wherein activating the ventilation system comprises activating an exhaust fan of the ventilation system to exhaust air from within the enclosed space to the environment outside of the enclosed space.

10. The method of claim 1, wherein activating the ventilation system comprises activating a forced air damper of the ventilation system to enable air within the enclosed space to be exhausted into the environment outside of the enclosed space.

31. The method of claim 1, wherein generating the control signal configured to operate the ventilation system further comprises generating the control signal responsive to a value of the electrical characteristic of the motor being outside of a predefined range.

11. A system to provide ventilation for an enclosed space, the system comprising:

a ventilation system positioned relative to the enclosed space to exhaust air from the enclosed space into an environment outside of the enclosed space;

a sensor to generate a first signal indicative of an electrical characteristic of a motor, the electrical characteristic being sensed during an operation of the motor to open or close a door to the enclosed space; and

a controller including one or more processors in communication with the sensor and the ventilation system, the controller configured to

activate the ventilation system to exhaust air from within the enclosed space to an environment outside of the enclosed space in response to determining based on the first signal from the sensor that the door is in a process of opening or closing.

12. The system of claim 11, further comprising an electrical interface configured to receive a connection for providing operating power to the motor.

13. The system of claim 12, wherein the sensor is configured to generate the first signal in response to detecting a current drawn by the motor through the electrical interface.

14. The system of claim 11, wherein the enclosed space is a garage.

15. The system of claim 11, wherein the electrical characteristic is selected from the group consisting of a current, a voltage, a power, and a frequency of the motor.

16. The system of claim 11, wherein the ventilation system comprises an exhaust fan positioned to exhaust air from the enclosed space into the environment outside of the enclosed space.

17. The system of claim 11, wherein the first signal is indicative of opening of the door.

18. The system of claim 17, wherein the controller is configured to

receive a second signal indicative of closing the door to the enclosed space during an operation of the ventilation system;

and

responsive to receiving the second signal, deactivate the ventilation system after a duration of time.

19. The system of claim 11, wherein the first signal is indicative of closing of the door.

20. The system of claim 11, further comprising a temperature sensor to generate a second signal indicative of a temperature within the enclosed space,

wherein the controller is configured to

determine, based on the second signal, that the temperature is above a threshold, and

operate, responsive to determining that the temperature is above the threshold, the ventilation system to exhaust air within the enclosed space to the environment when the temperature is above the threshold.

21. A device to provide ventilation for an enclosed space, the device comprising:

a sensor to generate a first signal indicative of an electrical characteristic of a motor, the electrical characteristics being sensed during an operation of the motor to open or close a door to the enclosed space; and

a controller including one or more processors in communication with the sensor and a ventilation system, the controller configured to

activate the ventilation system to exhaust air from within the enclosed space to an environment outside of the enclosed space in response to determining based on the first signal from the sensor that the door is in a process of opening or closing.

22. The device of claim 21, further comprising an electrical interface configured to receive a connection for providing operating power to the motor.
