ENVIRONMENTAL CONTROL FOR HVAC SYSTEM

摘要

A system for controlling energy consumption in a building having a heating, ventilation and air-conditioning (HVAC) which includes using an external application to perform HVAC energy consumption optimization algorithms and other external energy control functions and transmit application control data to a building automation system (BAS), which in turn provides hardware level equipment control for the HVAC system. The external application evaluates equipment data received from the HVAC system by way of the BAS and processes these equipment data to provide application control data back to the BAS. The application control data are calculated to achieve a desired operating efficiency for the HVAC system.

1. A method for controlling an HVAC system, the method comprising:
configuring a building automation system to communicate with an external application; and determining, based on a status check, whether to permit the building automation system to control the HVAC system with information provided by the external application or with information provided from a normal control sequence pre-programmed into the building automation system, wherein, upon permitting the building automation system to control the HVAC system with information provided by the external application, communication between the external application and the HVAC system includes:
obtaining equipment data from the HVAC system;processing the equipment data with the external application to generate application data;providing the application data to the building automation system; andwith the building automation system, converting the application data to control instructions to direct at least one environmental parameter associated with the HVAC system to a desired value.
