Solution Overview
Problem
Existing air-conditioning systems fail to effectively detect and adjust to temperature or air component stratification in indoor spaces, leading to inefficient air-conditioning control.
Innovation Solution
A replacement air-conditioning system that forms stratification of temperature and air components by supplying conditioned air to the lower side of a room and discharging indoor air from the upper side, using detection units to measure temperatures and air components at specific heights, and a control unit to determine and adjust the boundary height of stratification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature is detected at a preset temperature stratification height, then air-conditioning control is performed based on detection value, but the detected temperature value does not necessarily reflect the actual stratification state of temperature or air component
Solution Approach 1:
The detection space is segmented into multiple height zones (first height above assumed boundary, second height below assumed boundary) to capture temperature differences across the stratification interface. This segmentation allows the system to detect whether the actual boundary exists between these heights by comparing temperature differences, thereby accurately grasping the stratification state without losing critical information.
2Reliability
If air-conditioning system supplies conditioned air and discharges indoor air to form stratification, then clean zone is created at lower part of room, but system complexity increases due to multiple detection heights and boundary determination
Solution Approach 1:
The control unit receives temperature data from detection units at multiple heights, determines the actual boundary height based on temperature differences, and feeds this information back to adjust air supply and discharge operations. This feedback mechanism enables the system to dynamically adapt to changing stratification states, improving reliability while managing complexity through automated boundary determination algorithms.

AI summary
There are provided a replacement air-conditioning system and the like capable of detecting information suitable for grasping a state of stratification of a temperature or an air component. The replacement air-conditioning system is configured to be able to form stratification of a temperature or an air component in a room by supplying conditioned air to a lower side of the room and discharging indoor air from an upper side of the room, and includes a detection unit that detects the temperature or the air component in the room. The detection unit detects temperatures or air components at a first height set above an assumed boundary height of the stratification in the room and a second height set below the assumed boundary height.
