Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioning panels require a significant distance from the room partition for air induction and heat exchanger placement, limiting cooling capacity to sensible heat only and increasing space requirements, while also necessitating separate components for heating and cooling.
Innovation Solution
The induction air-conditioning panel with increased inductance utilizes the Coanda effect and dynamic air pressure conversion to enhance air recirculation and heat transfer efficiency, allowing for a compact design with a heat exchanger that can handle both sensible and latent heat, and integrates heat recovery functionality directly adjacent to the room partition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the heat exchanger is placed close to the room partition, then the installation space is reduced, but the air induction capacity is insufficient
Solution Approach 1:
The patent employs dynamic air pressure conversion where high-speed air flow from the diffusion panel creates a dynamic pressure that is converted into static pressure to enhance air induction. This dynamic mechanism allows the system to achieve sufficient air induction capacity even when the heat exchanger is positioned close to the partition, resolving the contradiction between compact installation space and air induction performance
Solution Approach 2:
The system utilizes pneumatic principles by converting dynamic air pressure into static pressure through the diffusion panel. The high-velocity air stream creates a pressure differential that drives air induction, enabling effective air intake without requiring large distances from the partition, thus achieving both compact installation and adequate air induction capacity
2Productivity
If the cooling water temperature is lowered below dew point, then latent heat removal capability is improved, but condensation flow control becomes difficult
Solution Approach 1:
The patent introduces a vertical dimension to condensate management by implementing a sloped heat exchanger surface that directs condensation downward into a collection tray. This dimensional approach allows the system to use low-temperature cooling water for enhanced latent heat removal while effectively managing condensate discharge through gravity-driven flow along the inclined surface, resolving the contradiction between cooling capacity and condensate control
3Productivity
If the distance between diffusion panel and heat exchanger is increased, then air induction is improved, but the device dimensions increase
Solution Approach 1:
The patent changes the velocity parameter of air flow to compensate for reduced distance. By increasing the air velocity from the diffusion panel, the system generates sufficient dynamic pressure to maintain effective air induction even with minimal spacing between the diffusion panel and heat exchanger. This parameter change allows the device to achieve both compact dimensions and adequate air induction performance
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 enhances cooling capacity, reduces installation space, and enables efficient heat recovery by intensifying air induction and pressure differences, allowing for both sensible and latent heat management with reduced power consumption and compact dimensions.
Implementation Method 1
the use of air wall inside the unit (for which is flowing at high speed air from slots or perforated holes in the diffusion panel) intensifies the phenomenon of induction the recirculating air from the room. At the same time, the use of air blowing on the vertical partition at some angle, the Coanda effect is additionally used.
Implementation Method 2
the dynamic pressure of the air flowing out of the slots or perforated holes at high speed is converted into an increase in static pressure and the pressure difference between blowing and suction side.
