Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient energy management in buildings with multiple discrete air conditioner units, as users often fail to adjust settings to energy-efficient modes when spaces are unoccupied, leading to increased energy consumption.
Innovation Solution
A building management system that includes operational mode sensors to detect and wirelessly confirm the operational status of air conditioner units, allowing for centralized control and scheduling to optimize energy usage across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually control discrete air conditioner units, then ease of operation is improved, but energy efficiency deteriorates when building is unoccupied
Solution Approach 1:
The air conditioner unit automatically detects occupancy status through sensors (motion, temperature, humidity) and autonomously adjusts its operational mode without requiring user intervention. When unoccupancy is detected, the system automatically transitions to energy-saving mode, resolving the contradiction between ease of manual operation and energy efficiency during unoccupied periods
Solution Approach 2:
The system continuously monitors environmental parameters (temperature, humidity, motion detection) and uses this feedback to dynamically adjust the air conditioner's operational state. This closed-loop control ensures the unit responds automatically to occupancy changes, maintaining energy efficiency while preserving user convenience through automated decision-making
2Loss of energy
If centralized control is implemented to manage multiple air conditioner units, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distributed intelligent units, where each air conditioner unit independently possesses sensing and decision-making capabilities. This segmentation eliminates the need for a complex centralized control system while achieving energy efficiency through local autonomous operation based on real-time environmental feedback

AI summary
This disclosure relates to methods, systems, and devices for detecting an operational mode of a building component of an environmental control system. In some instances, the apparatus may include a sensor for outputting a signal related to a measure of power drawn by the building component. The sensor may be a current sensor associated with a power cord of an air conditioning unit. The signal output by the sensor may be received by a signal conditioning circuit for conditioning the signal received from the sensor such as, for example, by amplifying and/or filtering. A comparator may be configured to compare the conditioned signal to a specified threshold associated with an ON condition and/or an OFF condition of the building component. The apparatus may include a wireless interface configured to wirelessly transmit a determination of whether the building component is ON or OFF based on the result determined by the comparator.
