AI Technical Summary

Technical Problem

HVAC systems face challenges in adapting to changing building layouts and user demands without requiring a complete redesign, as they are often controlled using static setpoints that do not account for dynamic changes in environmental conditions or user behavior.

Method used

The method involves providing an HVAC controller with spoofed sensor signals that mimic or differ from actual environmental conditions to manipulate the system's behavior, allowing for adaptive control without altering the existing HVAC system or controller, thereby enabling flexibility and efficient energy management.

Benefits of technology

This approach allows for real-time adjustment of HVAC system operations to match changing user demands and environmental conditions, reducing energy consumption while maintaining comfort, without the need for extensive system redesign or updates.

Abstract

The disclosure relates to a method and system for operating an HVAC system. The HVAC system comprises an HVAC unit for conditioning an interior environment of a building and an HVAC controller for controlling the HVAC unit based on a sensor signal that is indicative of a measured state of the interior environment. The method comprises providing the HVAC controller with a spoofed sensor signal that is indicative of a spoofed state of the interior environment, and having the HVAC controller control the HVAC unit based on the spoofed state.
