Solution Overview
Problem
Conventional air conditioning systems require manual prioritization of indoor units based on space conditions, which is inefficient and time-consuming, especially during insufficient capacity states where multiple indoor units exceed the outdoor unit's capacity.
Innovation Solution
The system employs surface temperature measuring devices and cameras to automatically determine the heat capacity and type of space, allowing indoor units to adjust their operation based on the change in surface temperature and space type, prioritizing units in server rooms and areas with higher temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual prioritization of indoor units is implemented, then the outdoor unit capacity can be managed during insufficient capacity states, but the system requires user intervention and preset configuration which is time-consuming and inefficient
Solution Approach 1:
The indoor units automatically detect server rooms using cameras and surface temperature measurements, then self-adjust their operation priorities without user intervention. The system performs self-diagnosis and self-configuration by identifying spaces with servers based on thermal characteristics and visual recognition, eliminating the need for manual priority presetting.
Solution Approach 2:
The system performs preliminary detection of server rooms and pre-establishes operation priorities before insufficient capacity states occur. By continuously monitoring surface temperatures and capturing images to identify server locations in advance, the system is ready to automatically adjust priorities when capacity constraints arise, rather than requiring real-time user input.
2Reliability
If uniform operation priority is assigned to all indoor units, then the system configuration is simple, but critical spaces such as server rooms cannot receive preferential treatment during capacity constraints
Solution Approach 1:
The system applies different operation priorities to different indoor units based on their local characteristics. By detecting server rooms through cameras and surface temperature measurements, the system identifies which specific locations require preferential treatment and assigns higher priorities only to those units serving critical spaces, while maintaining standard priorities for other units.
Solution Approach 2:
The system replaces manual configuration methods with automated detection mechanisms. Instead of requiring users to manually identify and configure priorities for critical spaces, the system uses cameras to capture images and surface temperature measuring devices to detect thermal characteristics, automatically identifying server rooms and establishing priorities through sensor-based detection rather than human intervention.
3Measurement precision
If the system continuously monitors and adjusts all indoor units, then optimal temperature control is achieved, but energy consumption and system complexity increase
Solution Approach 1:
The system applies full monitoring and priority adjustment only to indoor units serving detected server rooms, while applying reduced or standard control to other units. By using cameras and surface temperature sensors to identify which spaces contain servers, the system focuses its measurement and control resources on critical areas rather than uniformly monitoring all spaces with equal intensity.

AI summary
An air conditioning system includes: a plurality of indoor units each configured to condition air in a target space; and an outdoor unit connected to the plurality of indoor units. Each of the plurality of indoor units has a surface temperature measuring device configured to measure a surface temperature of an object in the target space. When a total of capacities requested by the plurality of indoor units is larger than a capacity of the outdoor unit, each of the plurality of indoor units performs a process corresponding to a change amount of the surface temperature per unit time.
