Air-conditioning system, air conditioner, and method for recognizing air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems face challenges in efficiently managing and controlling multiple air conditioners within a refrigerant system, particularly in recognizing new units or units that have undergone repairs, which can disrupt the air-conditioning control process and comfort levels.
Innovation Solution
The system employs a communication network where air conditioners within the same refrigerant system communicate through internal lines and those across different systems communicate through external lines, enabling a recognition process to be executed concurrently with control processes using time-division multiplexing and frequency-based signal transmission to distinguish and manage units without interrupting the air-conditioning control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a recognition process is executed to identify air conditioners in the system, then the management and control accuracy of air conditioners is improved, but the air-conditioning control process is interrupted and comfort levels deteriorate
Solution Approach 1:
The patent implements periodic action by separating the recognition process from the control process in time. The recognition process is executed during specific recognition periods when control operations are suspended, while control operations run during control periods. This periodic alternation allows both processes to function without interfering with each other, ensuring accurate recognition without compromising control continuity and comfort levels.
2Device complexity
If air conditioners communicate through a shared communication line, then the system complexity is reduced, but communication interference occurs between recognition signals and control signals
Solution Approach 1:
The patent applies periodic action by dividing communication time into distinct recognition periods and control periods. During recognition periods, only recognition signals are transmitted on the shared communication line, while during control periods, only control signals are transmitted. This time-division approach maintains the simplicity of the shared communication line structure while eliminating signal interference between the two types of communications.
3Measurement precision
If the recognition process is executed to identify new or repaired air conditioners, then the system management accuracy is improved, but the productivity of air-conditioning control is reduced
Solution Approach 1:
The patent implements periodic action by scheduling recognition processes during designated recognition periods when control operations are temporarily suspended. This allows the system to maintain high management accuracy by thoroughly executing recognition procedures without continuously interrupting control operations. The control process resumes during control periods, ensuring that productivity losses are minimized while still achieving accurate system management.

AI summary
A recognition process for an air conditioner is executed while the deterioration of the environment due to stoppage of the air conditioner is suppressed. In an air-conditioning system in which a plurality of air conditioners belonging to an identical refrigerant system are connected through a communication line inside the identical system and a plurality of air conditioners belonging to different refrigerant systems are connected through a communication line outside the different systems, for the plurality of air conditioners belonging to the identical refrigerant system, a recognition process is executable while an air-conditioning control process is executed by transmission through at least the communication line inside the system.
