Air conditioning system, operation control method therefor, and operation control device for air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning systems fail to ensure that refrigerant leakage detectors are appropriately positioned after room layouts change, potentially leading to unsafe operation.
Innovation Solution
The system inhibits operation of the air conditioning device unless the detector and alarm are connected and properly positioned, allowing for relocation together with the alarm to maintain appropriate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detector is installed independently without connection requirements, then the installation is simple and flexible, but the detector may not be positioned at an appropriate location after room layout changes
Solution Approach 1:
The patent combines the detector with the alarm device into an integrated unit. The detector and alarm are connected via a connection portion, forming a combined safety device that is installed together as one unit, ensuring they remain at appropriate positions relative to each other and the air conditioning device.
Solution Approach 2:
The control unit receives connection state information from the detector and alarm to determine whether they are properly connected. Based on this feedback, the control unit controls the operation of the air conditioning device, ensuring that operation only occurs when the safety devices are correctly positioned and connected.
2Reliability
If the detector and alarm are connected and require proper positioning, then the safety and reliability are improved, but the system complexity increases
Solution Approach 1:
The detector and alarm are merged into a single integrated safety device with a connection portion that links them. This integration simplifies the overall system structure by reducing the number of separate components and their associated connection points, while still maintaining the required positioning relationship between the detector and alarm.
Solution Approach 2:
The connection state detection is performed automatically by the control unit receiving information directly from the detector and alarm. The system self-verifies the proper connection and positioning of safety devices without requiring manual inspection or complex external monitoring systems.

AI summary
An air conditioning system (100) includes an air conditioning device (10), a detector (45), and an alarm (60). The air conditioning device (10) has a control unit (AC), and conditions air in an indoor space (S). The detector (45) detects the concentration of refrigerant in the indoor space (S). The alarm (60) notifies of refrigerant leakage in the indoor space (S). The detector (45) or the alarm (60) transmits the connection state between the detector (45) and the alarm (60) to the control unit (AC). The control unit (AC) inhibits operation of the air conditioning device (10) in a state in which the detector (45) and the alarm (60) are not connected to each other.
