Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precooling or preheating operation is performed in absence control, then comfortableness when user returns is improved, but energy consumption increases
Solution Approach 1:
The system performs precooling or preheating operations in advance before the user returns to the target space. The operation detail determining unit calculates optimal operation details (start time, end time, temperature settings) based on predicted user return time, ensuring the space is ready for occupancy while minimizing unnecessary energy consumption during extended absence periods.
Solution Approach 2:
The system dynamically adjusts operation parameters (temperature settings, operation duration, light blocking degree) based on the calculated operation details. By optimizing these parameters according to predicted user behavior and environmental conditions, the system achieves the desired comfort level while reducing overall energy consumption compared to fixed parameter approaches.
2Use of energy by moving object
If light blocking apparatus is controlled during precooling/preheating, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The control system merges the control of the air conditioner and the light blocking apparatus into a unified operation detail determining unit. This integrated approach coordinates both devices based on the same calculated operation details (timing, temperature goals, solar radiation data), achieving synergistic energy savings while managing complexity through centralized control logic rather than separate independent systems.
Solution Approach 2:
The system uses solar radiation amount as feedback input to determine operation details. By continuously monitoring environmental conditions and adjusting the coordination between light blocking and air conditioning operations accordingly, the system optimizes energy efficiency while the feedback mechanism provides a structured approach to managing control complexity.
3Productivity
If machine learning is used to determine operation details, then productivity is improved, but device complexity increases
Solution Approach 1:
The operation detail determining unit employs machine learning algorithms that enable the system to automatically learn and optimize operation patterns based on historical data and environmental conditions. The system self-adjusts to improve productivity in determining optimal precooling/preheating parameters without requiring manual intervention or complex external control systems, as the learning algorithm autonomously refines operation details.

AI summary
A precooling operation/preheating operation control apparatus (100) includes: an air conditioner (10), a ventilation apparatus (20), a first control unit (41), a second control unit (42), and an operation detail determining unit (45). The air conditioner (10) performs heat exchange between air in a target space (R) for precooling or preheating and a heat medium. The ventilation apparatus (20) replaces part of the air in the target space (R) with outside air that is air outside a building. The operation detail determining unit (45) determines, on the basis of a set temperature of the target space (R) at a designated time and a quantity related to an outside air temperature, operation details of the air conditioner (10) and operation details of the ventilation apparatus (20) during a precooling operation or preheating operation.
