Solution Overview
Problem
Existing air conditioning systems do not effectively promote sufficient ventilation when a person is in a room, which can lead to decreased indoor air quality and the potential spread of infections like COVID-19.
Innovation Solution
An air conditioner equipped with a detection unit to monitor room load, a notification unit to alert the user, and a control unit that notifies the user of necessary ventilation based on detected load conditions, prompting the user to perform ventilation when the load variation is within a predetermined range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ventilation is performed only when no person is in the room, then energy consumption is reduced, but indoor air quality deteriorates when a person is present
Solution Approach 1:
The system continuously monitors room load conditions and uses this feedback to dynamically adjust ventilation operations. By detecting whether a person is present and determining appropriate ventilation timing based on load variations, the system ensures air quality maintenance while avoiding unnecessary energy consumption during unoccupied periods.
Solution Approach 2:
The ventilation control system transitions from a static approach to a dynamic one by continuously adapting ventilation timing and duration based on real-time room load conditions. The control unit adjusts ventilation strategies according to detected load variations, ensuring optimal air quality while minimizing energy use.
2Object-affected harmful factors
If ventilation is performed frequently to maintain air quality, then indoor air quality improves, but energy consumption increases
Solution Approach 1:
The system performs ventilation partially or excessively based on actual needs rather than continuously. By determining appropriate ventilation timing and duration based on room load conditions, the system provides sufficient ventilation to maintain air quality while avoiding excessive energy consumption that would result from continuous or overly frequent ventilation operations.
3Measurement precision
If the air conditioner monitors load conditions continuously, then ventilation timing accuracy improves, but device complexity increases
Solution Approach 1:
The air conditioner performs self-monitoring of room load conditions and automatically determines appropriate ventilation timing without requiring external intervention or complex additional systems. The control unit uses built-in detection capabilities to assess load conditions and make ventilation decisions, maintaining timing accuracy while avoiding excessive system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prompts users to perform ventilation when necessary, improving indoor air quality and reducing the risk of infection by ensuring adequate ventilation, even in rooms without a built-in ventilation function.
Implementation Method 1
The detection unit preferably includes a temperature sensor configured to detect a temperature in the room

AI summary
An air conditioner 10 includes a detection unit 130 configured to detect a load in a room, a notification unit 140 configured to notify a user of information, and a control unit 150, in which the control unit 150 causes the notification unit 140 to notify the user that ventilation is necessary when a load condition indicating that a variation of the load detected by the detection unit 130 is within a predetermined range in a first time period P1 is satisfied.
