Abstract:
The present invention relates to an automatic ventilation control system comprising: a ventilation fan mounted in a ventilation opening; an inlet shutter which is openable and closable installed at an air inlet; a gas sensor which includes a carbon dioxide sensor and/or an oxygen sensor for detecting the concentration of carbon dioxide and/or oxygen; and a control unit which receives the signal from the carbon dioxide sensor and/or the oxygen sensor for controlling the propelling of a ventilation fan. According to the present invention, when the concentration of carbon dioxide and/or oxygen detected by the carbon dioxide sensor and/or the oxygen sensor reaches the determined value, the control unit generates a control signal which propels the ventilation fan at a rotation rate varying in accordance with the concentration of carbon dioxide and/or varying inversely with the concentration of oxygen to enable ventilation via the ventilation opening.

Abstract:
A system for controlling airflow in a plenum, that comprises a worm gear and planetary gear removably coupled to a worm shaft and planetary shaft, respectively. The planetary shaft controls the movement of a damper between an open position permitting maximum airflow through the plenum, and a closed position restricting airflow through the plenum. A motor is positioned at the plenum for driving the worm shaft. The motor is controlled by a remotely located controller.The controller is connected to the motor through a cable with a detachable electrical connection between the cable and the controller, such as a jack and plug. A wall plate for housing the electrical connection is mounted on a wall or other structure. The wall plate has a first plate for housing the jack and a second plate with a flexible flange for removably securing the jack in the housing by snap fit insertion.
Abstract:
An 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 ECRV is configured have a size and form-factor that conforms 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.

Abstract:
A control system (502, 602) for controlling airflow through a vent assembly (118, 200, 200', 200'', 230, 250). The system (502, 602) includes a vent assembly (118, 200, 200', 200'', 230, 250) having a frame (202, 232, 252). The frame (202, 232, 252) includes an opening (204, 234, 260) to allow air to flow through the frame (202, 232, 252). The vent assembly (118, 200, 200', 200'', 230, 250) also includes a movable damper (206, 236, 256) for variably restricting the fluid flow through the opening (204, 234, 260) in the vent assembly (118, 200, 200', 200'', 230, 250), a motor (210, 238, 472) for controlling movement of the damper (206, 236, 256), and a sensor (214, 214', 214'', 214''') for determining the position of the damper (206, 236, 256). In addition, a controller (504, 606) is provided to control the motor (210, 238, 472) to vary the position of the damper (206, 236, 256) to thereby vary the airflow through the opening (204, 234, 260) in the vent assembly (118, 200, 200', 200'', 230, 250).
Abstract:
The invention relates to a load adjusting device comprising an element which modifies an area through which air flows (4), especially a valve mounted on a shaft (5). The element can be driven according to given parameters by an actuator which is optionally placed underneath and is provided with a position sensor (12) which emits a signal indicating the position of said element. The invention is characterized in that the position sensor (12) is arranged in an area of the actuator.
