Air-conditioning system control apparatus using degree of influence between air-conditioning indoor units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air-conditioning systems require additional light emitting and receiving devices to calculate the degree of influence between indoor units, which is inefficient and unnecessary.
Innovation Solution
An air-conditioning system control apparatus that calculates the degree of influence between indoor units based on operation data using an influence-degree calculation unit, eliminating the need for specific devices like light emitting and receiving devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light emitting and receiving devices are added to calculate the degree of influence between indoor units, then the degree of influence can be measured, but the device complexity and installation burden increase
Solution Approach 1:
The patent introduces a control device as an intermediary that collects operation data from multiple indoor units and calculates the degree of influence between them. This mediator processes the data centrally, eliminating the need for each indoor unit to have its own light emitting and receiving devices, thus reducing overall device complexity while maintaining measurement capability
Solution Approach 2:
The patent replaces the mechanical/optical measurement system (light emitting and receiving devices) with a data processing system. Instead of using physical light signals to measure influence, the system uses operation data (electrical/digital signals) to calculate the degree of influence, substituting a simpler electronic data processing approach for a complex optical measurement system
2Measurement precision
If light emitting and receiving devices are installed in each indoor unit, then spatial relationships can be determined, but installation burden and cost increase
Solution Approach 1:
The control device serves multiple functions: it manages operation data collection, performs degree of influence calculations, determines spatial relationships, and controls multiple indoor units. By making the control device universal and multi-functional, the system eliminates the need for specialized light emitting and receiving devices in each indoor unit, reducing installation burden while maintaining all necessary measurement and control capabilities
Solution Approach 2:
The patent extracts the measurement and calculation functionality from the individual indoor units and places it in a separate control device. This extraction removes the light emitting and receiving devices from each indoor unit, simplifying their design and reducing installation burden, while the control device handles all the complex measurement and spatial relationship determination tasks
