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. An environmental control system for a building, the system comprising:
a heating, ventilation and air-conditioning (HVAC) system configurable to change environmental aspects of the building to target parameters; a building automation system in communication with the HVAC system and configured to adjustably control at least one of the target parameters to a desired value; and an external application in communication with the building automation system and configured to evaluate equipment data received from the building automation system and to then process the equipment data to generate application data using an application control sequence, the external application provides the application data to the building automation system for controlling the HVAC system to achieve the desired value of the at least one of the target parameters, wherein the building automation system includes sequence selection logic to determine whether the default building automation system sequence or the external application control sequence shall be executed to control the HVAC system.
