Remote Controller Error Display With AC Unit Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In air-conditioning systems, when an abnormal condition occurs, it is challenging to quickly identify the type of apparatus, leading to delays in determining the necessary repair parts and resolving the issue, as maintenance operators need to visit the installation location to determine the apparatus type.
Innovation Solution
An air-conditioning system that includes an outdoor unit, an indoor unit, and a remote controller, where each unit stores identification information such as product model names and serial numbers, and the remote controller displays this information along with error details when an abnormal condition is detected, enabling rapid identification of the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the remote controller displays only error information without identification information, then the error notification function is simple and reliable, but the time required to identify the apparatus type and prepare repair parts increases significantly
Solution Approach 1:
The remote controller stores identification information (model name, serial number) in advance in its memory unit. When an abnormal condition occurs, this pre-stored information is immediately displayed together with error information, eliminating the need for maintenance operators to visit the installation location to determine apparatus type. This preliminary preparation of information directly reduces the time loss while adding minimal complexity to the remote controller.
2Productivity
If the remote controller stores and displays identification information, then the efficiency of abnormal condition response improves, but the complexity of the remote controller increases
Solution Approach 1:
The patent merges the identification information storage function with the existing remote controller by adding a memory unit that stores model names and serial numbers. The display unit, which already exists for showing error information, is extended to also display identification information. This combining approach improves productivity by enabling immediate apparatus identification while minimizing the increase in device complexity, as it utilizes and extends existing remote controller components rather than adding entirely new functional modules.

AI summary
An air-conditioning system includes an air-conditioning apparatus including an outdoor unit storing outdoor-unit identification information an indoor unit storing indoor-unit identification information, and a remote controller including a third memory configured to store the outdoor-unit identification information and the indoor-unit identification information and a display unit configured to display error information when an abnormal condition occurs in the air-conditioning apparatus. The remote controller is configured to obtain the outdoor-unit identification information from the outdoor unit and to obtain the indoor-unit identification information from the indoor unit. The remote controller is configured to store the obtained outdoor-unit identification information and indoor-unit identification information into the third memory. The remote controller is configured to cause the display unit to display the stored outdoor-unit identification information and indoor-unit identification information together with the error information when an abnormal condition occurs in the air-conditioning apparatus.
