Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ventilation device and air conditioner operate independently to reduce target substance concentration to meet criteria, then the target substance concentration is reduced to the required level, but the devices may operate more than necessary leading to increased energy consumption
Solution Approach 1:
The patent combines the control of the ventilation device and air conditioner into a single integrated control system. The controller coordinates both devices to work together, using the ventilation device primarily for target substance removal and the air conditioner for temperature control, thereby avoiding redundant operations and reducing overall energy consumption while maintaining reliable concentration control.
Solution Approach 2:
The system dynamically adjusts operational parameters (airflow rates, device activation states) based on real-time target substance concentration measurements. When concentration is already below the threshold, the controller reduces or stops ventilation device operation, thereby reducing energy consumption while maintaining the required concentration level.
2Reliability
If the ventilation device draws outside air into the target space, then the target state quantity is adjusted, but unnecessary outside air drawing increases energy consumption
Solution Approach 1:
The system uses feedback from target substance concentration measurements to control ventilation device operation. The controller continuously monitors concentration levels and adjusts outside air drawing accordingly - reducing or stopping ventilation when concentration is already acceptable, thereby maintaining reliable air state adjustment while minimizing energy consumption.
3Reliability
If the air treatment device treats air continuously, then the target state quantity is maintained, but unnecessary treatment increases energy consumption
Solution Approach 1:
The system applies partial action by operating the air treatment device only when and to the extent necessary. The controller monitors target substance concentration and activates the air treatment device only when concentration exceeds the threshold, rather than continuous operation, thereby maintaining reliable state quantity maintenance while reducing energy consumption.

AI summary
An air conditioning coordination system includes: an outside air introducing machine for adjusting a target state quantity of the target space by introducing outside air; an air treating machine including a treatment unit for adjusting the target state quantity by treating the air; a control unit for setting a first airflow rate of the outside air introducing machine and a second airflow rate of the air treating machine; and a storage unit for storing relationship information representing a relationship between a selected state quantity, the first airflow rate, and the second airflow rate. The selected state quantity is a state quantity of the target space different from the target state quantity and is changed using at least one of the outside air introducing machine and the air treating machine. The control unit sets the first and second airflow rates from the relationship information based on the selected state quantity.
