Air-conditioning control system
Solution Overview
Problem
Existing air-conditioning remote management systems do not allow for individualized management of air-conditioning control systems in buildings, nor do they effectively integrate control with general-purpose devices such as humidifiers and heaters.
Innovation Solution
An air-conditioning control system that connects air-conditioning apparatuses with general-purpose devices through a dedicated communication line, using an energy management gateway and a general-purpose device controller to coordinate control signals and manage energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a remote management system is used to monitor air-conditioning apparatuses, then equipment monitoring capability is improved, but individualized management and integrated control with general-purpose devices is not achieved
Solution Approach 1:
The energy management gateway is designed to perform multiple functions: it monitors air-conditioning apparatuses, controls general-purpose devices, and provides integrated management capabilities. This multi-functional design allows a single system to address both equipment monitoring and individualized management needs, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The energy management gateway acts as an intermediary device between the remote management system and various air-conditioning apparatuses and general-purpose devices. It enables integrated control and individualized management by mediating communication and coordination between different components, while the remote management system maintains its monitoring capabilities.
2Device complexity
If air-conditioning apparatuses are managed independently, then system simplicity is maintained, but integrated management with general-purpose devices is not achieved
Solution Approach 1:
The energy management gateway serves as an intermediary that enables integrated management without significantly complicating the overall system structure. It coordinates between air-conditioning apparatuses and general-purpose devices, providing integrated control functionality while maintaining relative system simplicity through centralized management.
Solution Approach 2:
The system merges the management of air-conditioning apparatuses and general-purpose devices into a unified control framework through the energy management gateway. This combining approach enables integrated management capabilities while avoiding the need for completely separate independent management systems.
3Adaptability or versatility
If cooperative control with general-purpose devices is implemented, then system versatility is improved, but communication infrastructure complexity increases
Solution Approach 1:
The energy management gateway acts as a communication intermediary that simplifies the infrastructure requirements for cooperative control. It handles the complexity of coordinating between air-conditioning apparatuses and general-purpose devices, enabling versatile cooperative control while maintaining a manageable communication infrastructure through centralized mediation.
