Solution Overview
Problem
Existing air conditioner test drive systems lack the ability to comprehensively and immediately confirm operation information, particularly the location of abnormality occurrence, on a portable terminal during a test drive.
Innovation Solution
A display device and method that includes a control unit to determine abnormalities in air conditioner components and display operation information on a portable terminal, featuring a display unit that shows time information and operation data in a graphical format, highlighting abnormal conditions for quick identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operation information is displayed in a conventional manner during test drive, then basic connection information can be obtained, but abnormality occurrence location cannot be immediately confirmed
Solution Approach 1:
The display screen is divided into multiple display regions, with the first display region showing operation information from the time before abnormality occurrence and the second display region showing operation information from the time of abnormality occurrence. This segmentation allows immediate visual comparison and identification of abnormality location without time loss.
2Reliability
If detailed operation information is displayed for all components, then complete monitoring is achieved, but display complexity and information overload increase
Solution Approach 1:
Different display regions are allocated different qualities of information presentation. The first display region presents normal operation information with standard display characteristics, while the second display region presents abnormality-related information with enhanced display characteristics (such as different background color, border, or icon) to highlight the abnormality occurrence location without overwhelming the entire display.
3Adaptability or versatility
If conventional test drive monitoring is used, then basic operation data can be viewed, but comprehensive confirmation of operation states requiring expensive dedicated devices
Solution Approach 1:
The portable terminal is designed to perform multiple functions: it displays connection information, monitors operation states, identifies abnormality locations, and provides comprehensive test drive monitoring capabilities that previously required expensive dedicated devices. The terminal serves as a universal monitoring tool for all air conditioner components during test drive.

AI summary
A display device which displays operation information of an air conditioner in which an outdoor machine including an outdoor heat exchanger and an indoor machine including an indoor heat exchanger are connected. The display device includes a control unit that determines whether or not abnormality occurs in the outdoor machine or the indoor machine when the air conditioner operates, and a display unit which is controlled by the control unit so as to display time information and to display a plurality of operation information display regions for displaying operation information corresponding to the time information, in line. In a case where the control unit determines that the abnormality has occurred in the outdoor machine or the indoor machine, the control unit controls the display unit to display operation information of the outdoor machine or the indoor machine in which the abnormality has occurred, in the operation information display region.
