Two-Stage Water Atomization Layout for Pump-Free Air Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning appliances using water pumps are prone to interruptions due to abrasive particle solids, leading to wear and contamination issues, and reservoirs can harbor fungi and bacteria growth, causing bad odors.
Innovation Solution
The air conditioning appliance directly captures water from the supply network and atomizes it in two stages, eliminating the need for a water pump and reservoir, producing an ultrafine mist for enhanced thermal exchange through a pre-atomizer and main atomizer system controlled by an electrovalve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a water pump is used to pull water from the reservoir, then water can be delivered to the fan for atomization, but the pump is prone to interruptions due to abrasive particle solids causing wear and contamination
Solution Approach 1:
The patent removes the water pump and reservoir from the system, extracting the problematic components that caused reliability issues. Water is delivered directly from the water supply network to the atomizer, eliminating the pump entirely and thus eliminating the reliability problem while maintaining water delivery capability.
Solution Approach 2:
The system uses the water supply network's existing pressure and flow to deliver water directly to the atomizer without requiring a pump. The water supply infrastructure serves the system's needs directly, making the system self-sufficient and eliminating the unreliable pump component.
2Quantity of substance
If a reservoir is used to store water, then water can be supplied to the pump, but the reservoir becomes a breeding ground for fungi and bacteria causing bad odors
Solution Approach 1:
The patent removes the reservoir from the system, extracting the component that served as a breeding ground for bacteria and fungi. By eliminating the stored water reservoir, the system eliminates the harmful biological growth and associated odors while still maintaining access to water through the direct supply network connection.
3Productivity
If conventional single-stage atomization is used, then water can be sprayed into the room, but the atomization is not fine enough for effective thermal exchange
Solution Approach 1:
The patent divides the atomization process into two distinct stages: pre-atomization and final atomization. The pre-atomizer breaks water into smaller droplets first, then the main atomizer further atomizes these droplets into ultrafine mist. This segmentation of the atomization function achieves the required fineness for effective thermal exchange.
Solution Approach 2:
The pre-atomizer performs preliminary atomization of water before it reaches the main atomizer. This preliminary action of breaking water into smaller droplets beforehand enables the main atomizer to produce ultrafine mist more effectively, achieving the required atomization fineness for optimal cooling efficiency.
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
This solution prevents contamination, reduces energy consumption, and maintains air quality by ensuring all water is transformed into a fine mist, reducing heat effectively without the risk of bacterial growth or pump failures.
Implementation Method 1
a pre-atomizer (8) that contains peripheral radial fins that allow the pre-atomization of water before sending it to the conic disc or main atomizer (9)
Implementation Method 2
the main atomizer (9) that produces the final atomization, creating a ultrafine mist that helps the thermal exchange between the mist and the air
Implementation Method 3
The air conditioning appliance must come associated to a fan to spread this mist to the room

AI summary
BUILDING FEATURE APPLIED IN AIR-CONDITIONING APPLIANCE, capable of enriching the air with atomized water droplets in two stages, where in a first moment the water sent directly from the water supply network is pre-atomized in an appliance (8); being then delivered to the main atomizer (9), which produces the final atomization, creating an ultrafine mist that facilitates the thermal exchange between the mist and the air. The air-conditioning appliance must be associated to a fan so as to spread this mist to the room.
