Switching control board for air conditioning system, air conditioning system, and adaptive control method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high design cost and use limitations of outdoor units in air conditioning systems due to the requirement for synchronous development with specific indoor units, leading to inflexible and costly replacements.
Innovation Solution
A switching control board is introduced between the outdoor and indoor units, featuring an outdoor unit communication module, detection module, and control module to adaptively control the outdoor unit based on the type of indoor device, eliminating the need for fixed communication protocols and enabling flexible use of outdoor units with various indoor devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outdoor unit and indoor unit are synchronously developed with fixed communication protocols, then the system operates reliably, but the design cost increases and the outdoor unit becomes limited to specific indoor unit models
Solution Approach 1:
The patent introduces a switching control board as an intermediary device between the outdoor unit and indoor unit. The switching control board includes a detection module that identifies the indoor unit type and a control module that generates corresponding control parameters. This intermediary handles the communication protocol adaptation, allowing the outdoor unit to work with different indoor unit models without requiring synchronous development for each combination, thus resolving the contradiction between reliability and adaptability
Solution Approach 2:
The patent segments the control system into three independent parts: the outdoor unit, the switching control board, and the indoor unit. The switching control board is a separate, standalone component that can be independently developed and configured. This segmentation allows the outdoor unit to maintain fixed communication protocols while the switching control board adapts to different indoor unit types, solving the contradiction between maintaining reliable fixed protocols and achieving versatility
2Device complexity
If the outdoor unit is designed to work with specific indoor unit models, then the communication protocol is simplified, but the development cost increases and replacement flexibility decreases
Solution Approach 1:
The switching control board serves as a mediator that handles the complexity of communication protocol adaptation. Instead of designing different protocols for each outdoor-indoor unit combination, the switching control board detects the indoor unit type and generates appropriate control parameters. This concentrates the complexity in a single, reusable component rather than requiring complex custom designs for each unit pair, reducing development cost and improving replacement flexibility
Solution Approach 2:
The switching control board is designed as a universal component that can work with multiple types of indoor units. The detection module identifies different indoor unit types, and the control module adapts the control parameters accordingly. This multi-functional design allows a single outdoor unit combined with a switching control board to serve multiple indoor unit models, reducing the need for multiple specialized outdoor unit designs and lowering overall development costs

AI summary
A switching control board includes an outdoor unit communication module configured to establish a communication connection between the switching control board and an outdoor unit of an air conditioning system, a detection module configured to detect a type of an indoor device of the air conditioning system that is connected to the switching control board, and a control module connected to the outdoor unit communication module and the detection module. The control module is configured to obtain a control parameter based on the type of the indoor device and send the control parameter to the outdoor unit via the communication connection between the switching control board and the outdoor unit to control the outdoor unit.
