Air conditioning system having multiple outdoor units and multiple indoor units, method and device for operating air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-split air conditioning systems require extensive wired communication deployments, which are time-consuming and inefficient, especially when adding new units, and limit working efficiency.
Innovation Solution
The air conditioning system integrates both wired and wireless communication methods, allowing new indoor units to join the network via factory settings, eliminating the need for special wire deployment by using a main outdoor unit that can communicate with both wired and wireless indoor units, and establishing power line communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for all indoor units, then communication reliability is improved, but installation complexity and time increase due to special wire deployment requirements
Solution Approach 1:
The system segments indoor units into two types: first indoor units with wired communication capabilities and second indoor units with wireless communication capabilities. This segmentation allows different communication methods to be applied to different units, maintaining reliability for units that require it while improving installation efficiency for units where wireless is sufficient.
Solution Approach 2:
The outdoor unit is designed with multi-functionality to support both wired communication (via first wired controller) and wireless communication (via second wired controller). This universal communication interface allows the outdoor unit to work with both types of indoor units, enabling flexible system configuration without requiring separate systems for wired and wireless units.
2Adaptability or versatility
If new indoor units are added to the system, then system functionality is improved, but wire deployment time increases requiring redeployment of communication wires
Solution Approach 1:
Second indoor units are pre-configured with wireless communication capabilities at the factory. When adding these units to the system, no additional wire deployment is needed as they can join the network wirelessly through factory settings, significantly reducing installation time while maintaining system expandability.
Solution Approach 2:
The second wired controller acts as an intermediary that enables wireless communication between second indoor units and the outdoor unit. This intermediary component allows new units to be added to the system without requiring physical wire connections, thus reducing wire deployment time while maintaining system expandability.
3Reliability
If only wired communication is supported, then communication stability is improved, but device complexity increases due to requiring first model outdoor units and special wire deployment
Solution Approach 1:
The communication system is designed to be dynamic and adaptive, allowing the outdoor unit to automatically select between wired and wireless communication modes based on the type of indoor unit being connected. This dynamic approach maintains communication stability through wired connections when available while reducing device complexity by using wireless connections when appropriate.
Solution Approach 2:
The system changes communication parameters (wired vs. wireless mode) based on the indoor unit type. First indoor units use wired communication parameters for stable connections, while second indoor units use wireless communication parameters. This parameter change approach maintains stability for units that need it while reducing overall system complexity by not requiring all units to use wired communication.
