Cold storage including a sliding door having a vertical drain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cold storage facilities for pharmaceuticals and similar applications, a significant amount of dew condensation water forms due to the large temperature difference between the inside and outside of the storage chamber, leading to inefficient drainage as the water may not be completely drained through the existing drain holes.
Innovation Solution
The implementation of a cold storage design that includes a sliding door with a vertically extending drain channel at its end portions and a porous body with water permeability attached to the upper surface of the sliding door, establishing fluid communication with the drain channel to enhance drainage efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drain hole is formed in the lower frame to drain dew condensation water, then the drainage function is provided, but the dew condensation water may remain on the lower frame without being completely drained
Solution Approach 1:
The drainage system is segmented into multiple components: the drain channel in the sliding door stile, the porous body attached to the sliding door, and the drain hole in the lower frame. This segmentation allows water to be collected and drained through multiple pathways, ensuring complete drainage without requiring a complex single-system solution.
Solution Approach 2:
The porous body acts as an intermediary element between the sliding door surface and the drain channel. It facilitates fluid communication and controls water flow from the sliding door into the drain channel, preventing water accumulation while maintaining a relatively simple overall structure.
2Productivity
If a porous body is attached to the upper surface of the sliding door to establish fluid communication with the drain channel, then the drainage efficiency is increased, but the device complexity increases
Solution Approach 1:
A porous body is attached to the upper surface of the sliding door to establish fluid communication with the drain channel. The porous structure allows dew condensation water to pass through while maintaining structural integrity, significantly improving drainage efficiency without requiring complex mechanical components.
Solution Approach 2:
The porous body changes the flow parameters of the dew condensation water by controlling its passage through the porous structure. This modifies the water flow rate and distribution, enabling efficient drainage while keeping the overall device structure relatively simple.
