Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the compressor shuts down when temperature abnormalities are detected, then the safety of the air conditioning system is ensured, but the air conditioning service and vehicle cooling function are interrupted
Solution Approach 1:
The patent changes the parameter handling approach by replacing abnormal temperature measurements with theoretically calculated values derived from other valid measurements (pressure and temperature parameters) and thermodynamic models, allowing the system to maintain operation while ensuring safety
Solution Approach 2:
The patent introduces theoretical calculation values as an intermediary between abnormal sensor readings and system control decisions. Instead of directly using abnormal measurements or shutting down, the system uses calculated theoretical values to bridge the gap, maintaining continuous operation while ensuring safety
2Measurement precision
If abnormal temperature measurements are used for control decisions, then real-time monitoring accuracy is maintained, but false shutdowns occur due to sensor abnormalities
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors temperature measurements, compares them against theoretical calculated values, and automatically replaces abnormal readings. This feedback loop maintains measurement precision while preventing false shutdowns
Solution Approach 2:
The patent introduces theoretical calculation values as an intermediary layer between sensor measurements and control decisions. This intermediary allows the system to verify measurement validity and replace abnormal readings without affecting compressor operation stability

AI summary
Disclosed are a method and apparatus for improving the operating reliability of a compressor, a computer storage medium, a computer device, and an air conditioning system. The method for improving the operating reliability of the compressor includes the following steps: A, obtaining, in real time, a set of measurements of a suction pressure, of a suction temperature, of a discharge pressure, and of a discharge temperature of the compressor; B, detecting whether the set of measurements of the suction temperature and of the discharge temperature are abnormal; and C, setting, in response to detecting that the set of measurements of the suction temperature or of the discharge temperature is abnormal, the abnormal set of measurements to be equal to a set of theoretical values, wherein the set of theoretical values is determined at least in part on the basis of the sets of measurements that are not abnormal.
