Remote Maintenance Server for Multi-Site Air Conditioner Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote total maintenance systems are unable to efficiently manage and reduce electricity consumption across multiple control sites, as they lack a power-saving feature to optimize the operation of indoor units in buildings such as structures, stores, and schools.
Innovation Solution
A remote maintenance server that detects continuously operated or non-operating indoor units and transmits control commands to adjust operation rates, set temperatures, and compressor capacities, using a waste operation mode to minimize energy usage, with communication through various networks like TCP/IP and RS-485.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional building management systems are used to control facilities in one building, then the control function is achieved, but the system cannot remotely manage multiple control sites and reduce energy consumption
Solution Approach 1:
The remote maintenance server is designed to universally manage multiple control sites through a single centralized platform. It can detect, diagnose, and control various types of indoor units (air conditioners, heat pumps, etc.) across different buildings, replacing the need for separate building management systems at each location. This multi-functional capability enables remote management of multiple sites while providing energy-saving features that were previously unavailable.
2Reliability
If indoor units operate continuously to maintain comfort, then the comfort level is maintained, but energy consumption increases
Solution Approach 1:
The system continuously monitors the operational status, temperature, and energy consumption of indoor units. Based on this feedback, the remote maintenance server automatically adjusts operation rates, set temperatures, and compressor capacities to optimize energy consumption while maintaining comfort. The system can detect when continuous operation is unnecessary and reduce or stop operation accordingly.
Solution Approach 2:
The system dynamically adjusts operational parameters such as operation rate, set temperature, and compressor capacity based on real-time conditions. Instead of fixed continuous operation, the indoor units can vary their operation rates and temperatures according to actual needs, enabling energy savings while maintaining comfort when required.
3Adaptability or versatility
If a remote total maintenance system is implemented to manage multiple control sites, then remote management is achieved, but the system lacks power-saving features
Solution Approach 1:
The system merges remote maintenance functionality with energy-saving control capabilities into a single integrated platform. The remote maintenance server combines diagnostic, monitoring, and energy optimization functions, allowing it to not only manage multiple control sites remotely but also actively reduce energy consumption through automated control adjustments.
