Demand control ventilation system with commissioning and checkout sequence control |
摘要 |
The disclosure relates to a Demand Control Ventilation (DCV) and/or Economizer system that is capable of drawing outside air into an HVAC air stream. In some instances, the DCV and/or Economizer system may be configured to help perform one or more system checks to help verify that the system is functioning properly. In some instances, the DCV and/or Economizer system may provide some level of manual control over certain hardware (e.g. dampers) to help commission the system. The DCV and/or Economizer system may store one or more settings and or parameters used during the commissioning process (either in the factory or in the field), so that these settings and/or parameters may be later accessed to verify that the DCV and/or Economizer system was commissioned and commissioned properly. |

1. A Demand Control Ventilation (DCV) and/or Economizer system that is configured to be attached to a roof top HVAC unit of a building, comprising:
a DCV and/or economizer unit having a damper and a controller integrated with and located at the DCV and/or economizer unit, wherein the controller includes a memory, and wherein the damper is configured to selectively control air flow from outside of the building and into the building; the controller is configured to control a position of the damper such that a desired air flow of outside air is drawn into the building; the memory of the controller storing one or more calibration parameters generated during a commissioning of the DCV and/or economizer unit, wherein the one or more calibration parameters includes a minimum damper position based on a desired non-zero ventilation rate of the building; an interface for retrieving one or more of the stored calibration parameters from the memory of the controller of the DCV and/or economizer unit for display to a user, and for receiving a command from a user to initiate and perform one or more user initiated tests of the DCV and/or economizer unit; and wherein the controller is configured to initiate and perform one or more tests of the DCV and/or economizer unit upon receiving the command from the user via the interface, the one or more tests comprising proving that the damper can successfully be moved from a first position to a second position and providing confirmation to the user. |
