Ducted Air Conditioning Sensor Mapping for Multi-Room Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Duct type air conditioning systems face poor user convenience as they require users to manually select the air-conditioned space and room temperature sensor for conditioning, leading to inefficient air distribution across multiple spaces with varying temperatures.
Innovation Solution
A duct type air conditioning system with a control device and controller that associates air-conditioned spaces with room temperature sensors, allowing automatic selection of the appropriate sensor for air-conditioning control based on detected temperatures, enabling precise control and simultaneous conditioning of multiple spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual selection of air-conditioned space and room temperature sensor is required, then the system can control multiple spaces, but user convenience deteriorates
Solution Approach 1:
The system enables self-service operation by automatically determining which room temperature sensor corresponds to the air-conditioned space the user wants to control. The control device receives operation information from the user, automatically identifies the target air-conditioned space and its associated sensor without requiring manual selection, and executes air-conditioning control. This eliminates the need for users to manually select both the air-conditioned space and sensor, significantly improving ease of operation while maintaining the ability to control multiple spaces.
2Productivity
If dampers are used to open and close air channels, then air distribution can be controlled, but the system cannot supply appropriate conditioned air to the desired air-conditioned space when multiple spaces have different temperatures
Solution Approach 1:
The system implements feedback control by continuously monitoring room temperatures through sensors and using this information to automatically determine the target air-conditioned space. The control device receives operation information, automatically identifies the desired space based on current temperature data and sensor associations, and adjusts air distribution accordingly. This feedback mechanism ensures that appropriate conditioned air is supplied to the specific air-conditioned space the user wants to control, even when multiple spaces have different temperatures.

AI summary
A duct type air conditioning system includes an air conditioner; a plurality of ducts that are disposed in a plurality of air-conditioned spaces that are supplied with conditioned air of the air conditioner; a plurality of room temperature sensors that are disposed in the air-conditioned spaces; a control device that controls the air conditioner; and controllers that control the air conditioner. The control device determines a room temperature sensor disposed in any of the air-conditioned spaces on which an air-conditioning starting operation is performed by the controllers by using sensor setting information in which the air-conditioned spaces and the room temperature sensors are associated with each other. The air conditioner includes an air-conditioning control degree calculating unit that calculates a degree of control of the air conditioner on the basis of a room temperature detected by the room temperature sensor determined by the control device.
