Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single control logic is pre-configured in the air conditioning water circulating system, then the system structure remains simple and easy to operate, but the system cannot adapt to different environmental conditions and load statuses, leading to reduced energy efficiency
Solution Approach 1:
The control system dynamically switches between multiple control logics (first control logic and second control logic) based on real-time detection of environmental parameters and load values. This dynamic adaptation allows the system to optimize energy efficiency under different operating conditions without requiring a completely complex reconfiguration of the control architecture.
Solution Approach 2:
The system changes the control parameter (control logic selection) based on detected environmental parameters and load values. When environmental parameters exceed thresholds or load values indicate high demand, the system switches from the first control logic to the second control logic, thereby adapting to varying operational conditions while maintaining manageable system complexity.
2Reliability
If the water-pump operates at rated flow rate to satisfy maximum indoor load demand, then the system ensures adequate cooling capacity, but energy consumption increases during low load demand periods
Solution Approach 1:
The water-pump flow rate is dynamically adjusted based on real-time detection of environmental parameters and load values. During low load demand periods, the system reduces the water-pump flow rate below the rated flow rate, thereby reducing energy consumption while still meeting the actual cooling demand. During high load periods, the system increases the flow rate to ensure adequate cooling capacity.
Solution Approach 2:
The control system continuously detects environmental parameters (such as temperature, humidity) and load values, then uses this feedback information to adjust the water-pump flow rate accordingly. This closed-loop feedback mechanism ensures that the cooling capacity matches the actual demand, preventing energy waste during low load periods while maintaining reliability during high load periods.
3Use of energy by moving object
If variable flow rate control mechanism is implemented with multiple control logics, then energy conservation is improved, but the system lacks the ability to switch between different control logics based on environmental status and load status
Solution Approach 1:
The system dynamically selects and switches between the first control logic and the second control logic based on real-time environmental parameters and load values. This dynamic logic switching capability enables the system to apply the most appropriate control strategy for current operating conditions, thereby optimizing energy conservation while maintaining full adaptability to different environmental and load scenarios.
Solution Approach 2:
The system changes the control logic selection based on detected parameters. When environmental parameters are within normal ranges and load values are low, the first control logic is applied for energy conservation. When environmental parameters exceed thresholds or load values indicate high demand, the system switches to the second control logic, thereby achieving both energy efficiency and adaptability.

AI summary
A method of controlling a water-pump of an air conditioning system used in an active air conditioning water circulating system includes: detecting an environmental parameter and a load value of the active air conditioning water system actively; adjusting a flow rate of a water-pump of the active air conditioning water system according to a first control logic when the environmental parameter is less than a first pre-default parameter and the load value is less than a load threshold; and, adjusting the flow rate of the water-pump according to a first control logic when the environmental parameter is not less than the first pre-default parameter or the load value is not less than the load threshold. The present disclosed example can enhance a flow control capacity for different environmental statuses via controlling the flow rate in the different environmental status according to the different control logic.
