Adaptive Cooling Capacity Control for Overheating Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooling systems with variable capacity face risks of overheating due to incorrect cooling capacity specifications from higher-level units, leading to potential damage, reduced service life, or explosions, as existing solutions fail to reliably detect and correct errors in setpoint transmissions.
Innovation Solution
The cooling system incorporates an adaptive unit that checks the plausibility of setpoints using temperature sensors and machine learning methods to predict required cooling capacity, autonomously increasing fan speed if specifications are deemed incorrect, and employs anomaly detection to prevent overheating.

1Use of energy by moving object
If the cooling capacity is reduced to minimize energy consumption and noise, then energy efficiency improves, but the risk of overheating increases due to potential errors in higher-level control systems
Solution Approach 1:
The cooling system implements a feedback mechanism where the actual cooling capacity is monitored and compared with the required cooling capacity. When a discrepancy is detected (indicating a potential error in the higher-level control system), the system automatically adjusts the cooling capacity to prevent overheating, thus maintaining safety while allowing energy reduction under normal conditions
Solution Approach 2:
The cooling system performs self-diagnosis and self-correction by monitoring its own operation. The control unit detects errors in setpoint transmission or cooling capacity specification autonomously and adjusts the cooling capacity without external intervention, enabling the system to protect itself against overheating while maintaining energy efficiency during normal operation
2Reliability
If the fan speed is increased to maximum to prevent overheating, then safety against overheating improves, but energy consumption and noise level increase
Solution Approach 1:
The cooling system dynamically adjusts the fan speed based on real-time conditions. Instead of operating at maximum speed continuously, the system varies the fan speed according to the actual cooling requirements and detected error conditions, achieving adequate safety while minimizing energy consumption and noise during normal operation
Solution Approach 2:
The system changes the operational parameters (fan speed, cooling capacity) based on the detected state. Under normal conditions, the system operates at optimized parameters for energy efficiency. When errors are detected, the parameters are adjusted to prioritize safety, thus achieving safety improvements without continuous high energy consumption
3Reliability
If autonomous error detection and correction functions are added to the cooling system, then safety and reliability improve, but device complexity increases
Solution Approach 1:
The control unit is designed to perform multiple functions: it not only controls the fan motor but also monitors the cooling capacity, detects errors in setpoint transmission, compares actual with required cooling capacity, and autonomously adjusts operations. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving improved safety

AI summary
The invention relates to a control method for a cooling system with variable cooling capacity, as well as to a cooling system with variable cooling capacity. Cooling systems are often used to prevent overheating of equipment. In cooling systems with variable cooling capacity, the cooling capacity is usually determined by a higher-level unit, for example, a higher-level controller. A malfunction of the higher-level unit can lead to overheating of the equipment being cooled, with negative consequences. The object of the invention is therefore to create a cooling system with variable cooling capacity that can detect and correct incorrect cooling capacity settings, thereby increasing the safety of the equipment being cooled.
