Humidifier With Dual Temperature Control for Rapid Humidity Regulation
Solution Overview
Problem
Existing humidifiers in test chambers struggle to maintain high humidity constancy, especially under rapidly changing conditions, and are costly due to the need for individually adapted designs for different chamber sizes, with water contamination and slow regulation being significant issues.
Innovation Solution
A modular humidifier with a container housing a water bath, equipped with a heating and cooling device using heat exchangers, and an aeration system to generate aerosol-free air bubbles, allowing for precise temperature control and rapid humidity adjustments, enabling both humidification and dehumidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large water bath is used in the humidifier, then humidification capacity is improved, but response speed and humidity regulation precision deteriorate
Solution Approach 1:
The water bath is divided into multiple separate containers (first water container and second water container) instead of using a single large water bath. This segmentation allows independent temperature control of each container, enabling faster response times while maintaining adequate water volume for humidification capacity.
2Quantity of substance
If water is placed inside the test chamber for humidification, then humidification effectiveness is improved, but water contamination and corrosion risks increase
Solution Approach 1:
The water containers are extracted from the test chamber interior and placed in the ambient environment. The humidifier introduces controlled amounts of water into the test chamber only when needed for humidification, rather than having a permanent water reservoir inside the chamber. This prevents water from absorbing pollutants and causing corrosion.
3Manufacturing precision
If individually adapted humidifiers are designed for different test chamber sizes, then humidification precision is improved, but manufacturing cost increases
Solution Approach 1:
The humidifier uses standardized, modular water containers that can be universally applied to different test chamber sizes. The system achieves precision humidification through controlled water introduction and temperature management rather than through custom-designed chambers, making the humidifier adaptable to various chamber configurations without requiring individual manufacturing for each size.
