Air Conditioning Ventilator Control to Reduce Maintenance Humidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance operation of air conditioners increases humidity in the room, leading to decreased user comfort.
Innovation Solution
An air conditioning system that includes an air conditioning device, a ventilator, and a ventilation controller to control the ventilator's operation during maintenance, preventing unnecessary humidity increases by ventilating the space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioning device performs maintenance operation to evaporate water droplets, then mold and odor prevention is improved, but room humidity increases causing decreased user comfort
Solution Approach 1:
The ventilator acts as an intermediary device that introduces outdoor air into the room during maintenance operation. This mediator balances the humidity increase caused by evaporation by providing drier outdoor air, thereby preventing excessive room humidity while maintaining the mold and odor prevention benefit
Solution Approach 2:
The system changes the operational parameters by activating the ventilator during maintenance operation. This parameter change (ventilator activation) modifies the room's air exchange rate and humidity levels, allowing the maintenance operation to proceed without causing excessive humidity accumulation
