Solution Overview
Problem
Existing evaporative air coolers waste condensed water, which is not reused, leading to inefficiency and water wastage.
Innovation Solution
An evaporative air cooler design that includes a housing with a water storage tank and a wet curtain filter net, where the condensed water is absorbed and re-evaporated for reuse, utilizing a fan to direct water vapor and a nano sponge for enhanced water absorption, allowing for the recycling of condensed water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If condensed water is discharged without reuse, then the device structure is simple, but water is wasted
Solution Approach 1:
The patent merges the water storage tank with the condensed water collection function by placing the wet curtain filter net inside the water storage tank. This integration allows condensed water to be automatically collected and reused for evaporation, reducing water waste without requiring a completely separate collection system.
Solution Approach 2:
The wet curtain filter net automatically absorbs condensed water from the accommodating cavity and delivers it to the water storage tank for reuse. The system serves itself by using the existing water circulation infrastructure to handle condensed water without requiring additional active pumping or complex control mechanisms.
2Loss of substance
If condensed water is reused through wet curtain filter net, then water waste is reduced, but the device complexity increases
Solution Approach 1:
The wet curtain filter net serves multiple functions simultaneously: it filters air passing through the water storage tank, absorbs condensed water from the accommodating cavity, and provides a surface for water evaporation. This multi-functionality reduces water waste while avoiding the need for separate dedicated components for each function.
Solution Approach 2:
The wet curtain filter net utilizes porous material properties to absorb condensed water through capillary action and allow water vapor to pass through. This passive absorption mechanism reduces water waste without requiring energy-consuming pumps or complex active water management systems.
3Quantity of substance
If nano sponge is added to water storage tank, then water absorption capacity is enhanced, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs nano sponge, a highly porous material, in the water storage tank to dramatically enhance water absorption capacity. The nano-scale porosity provides enormous surface area for water retention and evaporation, increasing the quantity of water that can be held and reused in the system.
Solution Approach 2:
The combination of wet curtain filter net and nano sponge creates a composite water management system that leverages the complementary properties of both materials. The filter net provides structural support and initial filtration, while the nano sponge enhances absorption capacity, together achieving superior water retention and reuse performance.
