Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidification and cooling systems face challenges in maintaining effective operation due to mineral deposition on evaporation panels, which reduces their porosity and effectiveness, and require regular cleaning while maintaining humidity control.
Innovation Solution
The system includes a configuration where the power flow rate generates a flow outside the evaporation panel to remove minerals by gravity, allowing for independent cleaning of porous evaporation panels without altering evaporation conditions, enabling precise control of humidity and temperature during cleaning phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water is supplied to evaporation panels for humidification, then humidity level is maintained or increased, but mineral deposition occurs on the panels reducing their porosity and efficiency
Solution Approach 1:
The system divides the evaporation panels into multiple independently controllable segments. Each panel can be individually cleaned by stopping water supply to adjacent panels while maintaining supply to others, ensuring continuous operation without complete system shutdown.
Solution Approach 2:
The system performs preliminary cleaning actions on evaporation panels by controlling water supply patterns. Water is directed to flow over panels to be cleaned, carrying away mineral deposits before they significantly reduce panel efficiency, maintaining optimal performance proactively.
2Reliability
If evaporation panels are cleaned to remove mineral deposits, then panel efficiency is restored, but humidity control may be disrupted during cleaning
Solution Approach 1:
The water supply system is segmented to allow individual panel cleaning while maintaining supply to other panels. This segmentation enables cleaning operations without complete system shutdown, preserving humidity control through continuous operation of remaining panels.
Solution Approach 2:
The water supply system dynamically adjusts flow distribution in real-time. During cleaning operations, the system dynamically redirects water flow to cleaning functions while maintaining adequate supply to operational panels, adapting to changing system requirements without manual intervention.
3Reliability
If water supply is increased to clean evaporation panels, then mineral removal is enhanced, but energy consumption and water usage increase
Solution Approach 1:
The system applies partial cleaning action by directing water flow only to specific panels requiring cleaning rather than all panels simultaneously. This selective approach uses minimal water and energy while effectively removing minerals from panels that need it, avoiding excessive consumption.
Solution Approach 2:
The cleaning operation is performed periodically rather than continuously. The system monitors panel conditions and initiates cleaning cycles only when mineral deposition reaches thresholds that would affect performance, reducing overall water and energy consumption while maintaining panel effectiveness.

Function Achieved in This Case
This approach allows for regular cleaning of evaporation panels while maintaining precise control over humidity and temperature, preventing mineral accumulation and ensuring the system's effectiveness and efficiency.
Implementation Method 1
water to evaporate through an adiabatic process. By passing through the porous evaporation panels impregnated with water, the airflow causes the water present in the evaporation panels to evaporate
Implementation Method 2
water to evaporate through an adiabatic process. The heat required for the water to vaporize is provided directly by the air. The airflow is thus cooled and its humidity level increases.
Implementation Method 3
the feed flow generates a flow out of the evaporation panel, at the lower part of the panel, carrying by gravity the minerals deposited on the evaporation panel.
