Air-conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems face inefficiencies when one component, either the outdoor air handler or the air conditioner, enters a non-temperature adjusting state, leading to a shortage or excess in air conditioning capacity, resulting in suboptimal temperature control and increased power consumption.
Innovation Solution
The air-conditioning system includes a control device that dynamically adjusts the air conditioning capacity of the other component to compensate for changes in the system's operating state, by modifying the to-be-supplied air temperature and air flow rates, ensuring optimal temperature adjustment and minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outdoor air handler and air conditioner operate independently without coordination, then each device can function autonomously, but the overall air conditioning capacity becomes unbalanced leading to shortages or excesses
Solution Approach 1:
The control device continuously monitors the operating states of both the outdoor air handler and air conditioner, and dynamically adjusts the air conditioning capacity of one device based on the state of the other, creating a closed-loop feedback system that maintains capacity balance while allowing autonomous operation
Solution Approach 2:
The system transitions from static independent operation to dynamic coordinated operation, where the air conditioning capacity of each device can be flexibly adjusted in real-time based on the other device's state, resolving the capacity imbalance without sacrificing operational autonomy
2Device complexity
If the air conditioning capacity is not adjusted when one device is in non-temperature adjusting state, then the system structure remains simple, but temperature control becomes suboptimal and power consumption increases
Solution Approach 1:
The control device uses feedback from the operating state detection to dynamically adjust air conditioning capacity, enabling optimal temperature control and energy efficiency without requiring complex manual intervention or overly complicated control architecture
3Productivity
If the air conditioning capacity is dynamically adjusted based on the other device's state, then temperature control optimality and energy efficiency improve, but the control system complexity increases
Solution Approach 1:
The control device implements a feedback mechanism that monitors the operating state of one device and automatically adjusts the air conditioning capacity of the other device, achieving optimal temperature control and energy efficiency through automated coordination rather than complex manual control systems

AI summary
It is an object of the present disclosure to collectively control an outdoor air handler and an air conditioner optimally.An air-conditioning system (100) includes an outdoor air handler (10) configured to adjust a temperature and a humidity of taken-in outdoor air and supply the air to a target space (SP1, SP2), an air conditioner (20) configured to adjust a temperature of air in the target space (SP1, SP2), and a control unit (30). The control unit (30) is configured to, in a case where one of the outdoor air handler (10) and the air conditioner (20) is in a non-temperature adjusting state in which the temperature of the air is not adjusted, change an air conditioning capacity of the other one of the outdoor air handler (10) and the air conditioner (20) compared with a case where the outdoor air handler (10) and the air conditioner (20) are in a temperature adjusting state in which the temperature of the air is adjusted.
