    摘要: Methods and systems for automatically calibrating one or more damper positions of a demand control ventilation system are disclosed. In one illustrative embodiment, a demand control ventilation system includes a damper for controlling a flow of outside air into a building. A controller may be programmed to automatically execute a calibration algorithm from time to time to calibrate one or more calibration damper positions such that a predetermined flow of outside air is drawn through the damper and into the building at each of the one or more calibration damper positions. This calibration can, in some instances, help increase the efficiency and/or utility of the demand control ventilation system.

    摘要: The present disclosure provides a method for operating an HVAC system for conditioning air of an inside space. The HVAC system has an economizer configured to control the intake of outside air into an HVAC air stream of the HVAC system. The method includes determining at least two parameters of the air of the inside space, where the at least two parameters are selected from a set of parameters from which an inside air dry bulb temperature, an inside air dew point, an inside air relative humidity, and an inside air enthalpy can be determined, either directly or indirectly. The method also includes determining at least two parameters of the outside air, where the at least two parameters being selected from a set of parameters from which an outside air dry bulb temperature, an outside air dew point, and an outside air enthalpy can be determined, either directly or indirectly. Based on one or more of the inside air dry bulb temperature, the inside air dew point, the inside air relative humidity, and the inside air enthalpy, a determination is made of whether dehumidification of the inside space is needed, and if dehumidification is not needed, the economizer is commanded to increase the intake of outside air into the HVAC air stream if the outside air dry bulb temperature is less than a dry bulb temperature reference, and if the outside air enthalpy is less than an enthalpy reference. If, alternatively, dehumidification is needed, the economizer is commanded to increase the intake of outside air into the HVAC air stream if the outside air enthalpy is less than the enthalpy reference, and if the outside air dew point is less than a dew point reference.

    摘要: Methods and systems for remotely monitoring and/or controlling a demand control ventilation system are disclosed. In one illustrative embodiment, a demand control ventilation device having a damper and a controller are provided. The damper may have a range of damper positions for controlling a flow of outside air into the building. The controller controls the damper positions such that a desired flow of outside air is drawn through the damper and into the building. A remote monitoring device may also be provided. The remote monitoring device may be located remotely from the demand control ventilation device, but in communication with or part of the controller. In some instances, the remote monitoring device may have a user interface for remotely monitoring and/or controlling at least certain aspects of the demand control ventilation system from the remote location.

    摘要: An actuator system having an actuator with a rotatable shaft. The shaft may have a first running time to rotate from a first position to a second position in one direction. The shaft may have a second running time to rotate from a first position to a second position in another direction. The first and second running times may be separately adjustable. A motor may be connected through a gear train to the rotatable shaft. A processor may control a rotation of the motor and thus the running times of the shaft. The running times may be adjusted with signals to the processor from a remote controller connected to the processor via a communications bus.
