Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional air distribution devices are used with horizontal outflow parallel to ceiling, then turbulent mixed ventilation is achieved, but air flow from multiple directions cannot be utilized and cooling efficiency is insufficient on very warm days
Solution Approach 1:
The air distribution device is divided into multiple independent air outlet surfaces (first air outlet surface and second air outlet surface) with different orientations. Each surface can independently direct air flow in different directions (horizontally parallel to ceiling and vertically perpendicular to ceiling), allowing the system to utilize air flow from multiple directions simultaneously while maintaining efficient cooling performance.
2Ease of operation
If supply air flows out horizontally parallel to ceiling panel, then even distribution of warm and cold air is achieved avoiding drafts, but supply air is not sufficiently cooled on very warm days
Solution Approach 1:
The invention adds a vertical dimension to air distribution by incorporating a second air outlet surface perpendicular to the ceiling, in addition to the horizontal first air outlet surface. This multi-dimensional approach allows simultaneously achieving even horizontal distribution (avoiding drafts) and enhanced cooling capacity through vertical air discharge, solving the temperature insufficiency problem on very warm days.
3Productivity
If radial outflow is used with central air outlet, then air conditioning of entire room is possible, but targeted outflow onto specific workplace cannot be achieved
Solution Approach 1:
Different portions of the air distribution device are assigned different functions: the first air outlet surface provides horizontal air flow for general room air conditioning coverage, while the second air outlet surface provides vertical air flow for targeted cooling of specific areas or workplaces. This local differentiation allows simultaneous achievement of comprehensive coverage and targeted outflow capability.
