Solution Overview
Problem
Outdoor units of air conditioners often experience poor heat dissipation due to their installation environment, leading to impaired cooling and heating performance and potential damage, which is typically detected only after significant performance issues arise, requiring manual troubleshooting.
Innovation Solution
A method and apparatus that monitor the environment temperature of the outdoor unit before and after operation, using a cloud server to compare real-time temperatures and control the unit's operation mode to prevent poor heat dissipation, allowing for early detection and automated intervention to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the outdoor unit is monitored using traditional manual troubleshooting methods, then the detection process requires human intervention and time-consuming checks, but the system complexity and automation level remain low
Solution Approach 1:
The outdoor unit performs self-detection of heat dissipation conditions by automatically monitoring its own temperature and comparing it with ambient temperature data, eliminating the need for manual troubleshooting and achieving automated self-diagnosis
Solution Approach 2:
The system establishes a feedback loop where temperature data from the outdoor unit and ambient environment are continuously collected, compared, and used to trigger automatic protective actions when heat dissipation deterioration is detected, creating a closed-loop monitoring system
2Measurement precision
If temperature monitoring is performed continuously to detect heat dissipation issues early, then the detection precision and timeliness improve, but the energy consumption and operational complexity increase
Solution Approach 1:
The system obtains ambient temperature data in advance from cloud servers before actual operation begins, allowing for preliminary assessment of heat dissipation conditions and enabling proactive protective measures without requiring continuous high-energy monitoring during operation
Solution Approach 2:
The system performs comprehensive temperature monitoring and comparison only when necessary to detect heat dissipation deterioration, rather than continuously at full capacity, optimizing the balance between detection precision and energy consumption
3Reliability
If the outdoor unit operates in poor heat dissipation conditions, then the cooling and heating performance deteriorates and damage may occur, but preventing operation reduces productivity and user convenience
Solution Approach 1:
The system takes preliminary protective actions by detecting heat dissipation deterioration early through temperature comparison and automatically adjusting operation or alerting users before actual damage occurs, preventing reliability issues while minimizing disruption to productivity
Solution Approach 2:
The system provides advance warning and protective measures against heat dissipation problems by comparing temperatures before critical failures occur, cushioning the system against potential damage and allowing for planned maintenance rather than unexpected failures

AI summary
A method for controlling an outdoor unit of an air conditioner includes: obtaining a first temperature of an environment in which the outdoor unit in a standby state is located; controlling the outdoor unit to operate for a first predetermined duration, and obtaining a second temperature of the environment in which the outdoor unit is located; reading a real-time temperature of the environment from a cloud server based on a range of a temperature difference between the second temperature and the first temperature; and controlling an operation of the outdoor unit based on a temperature difference between the real-time temperature of the environment from the cloud server and the second temperature.
