Air Conditioner Mode Selection for Aging Performance Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner monitoring systems can determine if a breakdown is caused by aging but fail to quantify the performance decrease due to aging, limiting user awareness and operational adjustments.
Innovation Solution
A control method that displays selectable operation modes on a terminal device, showing ranges of power consumption settings at purchase and current times, allowing users to select a target value and adjust the air conditioner's operation mode based on performance degradation, thereby optimizing power consumption and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioner operates in high power consumption mode to maintain cooling/heating capacity, then the cooling/heating capacity is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the operation mode selectable and adjustable based on user needs and actual performance conditions. The system dynamically transitions between first operation mode (high power consumption, high capacity) and second operation mode (low power consumption, reduced capacity) allowing optimal balance between cooling capacity and power consumption at different times
2Device complexity
If the air conditioner continues to operate with aged components, then the device complexity is reduced, but the performance decreases
Solution Approach 1:
The terminal device provides feedback to users about the air conditioner's performance status, power consumption characteristics, and operational history. This feedback mechanism enables users to make informed decisions about operation mode selection and potential maintenance needs, creating a closed-loop system that monitors and communicates performance degradation
3Use of energy by moving object
If the air conditioner operates in low power consumption mode to reduce energy usage, then the power consumption is reduced, but the cooling capacity decreases
Solution Approach 1:
The patent applies parameter changes by allowing users to switch between different operation modes that change key operational parameters. The first operation mode uses parameters optimized for high cooling capacity, while the second operation mode uses parameters optimized for low power consumption, enabling flexible adaptation to different environmental conditions and user priorities

AI summary
An operation mode selection image represents a first selection range of values of power consumption setting that are selectable in a first mode at the time of purchase of an air conditioner, a second selection range values of power consumption setting that are selectable in the first mode at a current time, a third selection range values of power consumption setting that are selectable in a second mode at the time of purchase of the air conditioner, and a fourth selection range values of power consumption setting that are selectable in the second mode at the current time. The relationship between the sizes of the first and second selection ranges and the relationship between the sizes of the third and fourth selection ranges represent a degree of decrease in the performance of the air conditioner over the period from the time of purchase to the current time.
