Clean Workshop Partition Design for Independent Environmental Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clean workshops face high energy consumption due to using a shared centralized return air system to control cleanliness, temperature, and VOC concentration across different process areas, which are not optimized for individual requirements.
Innovation Solution
A clean workshop design with partitioned areas, each equipped with independent return air systems and secondary humidification systems, allowing for localized control of cleanliness, temperature, and VOC concentration, reducing energy consumption by optimizing air circulation and supply volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared centralized return air system is used to control the entire clean production layer, then the cleanliness and VOC concentration can be maintained at the highest requirements, but energy consumption increases significantly
Solution Approach 1:
The clean production layer is divided into multiple independent clean production areas through partition walls. Each area has its own independent return air system with separate return air passageways, allowing individualized environmental control. This segmentation enables each area to be optimized according to its specific process requirements rather than forcing all areas to meet the highest cleanliness standards simultaneously, thereby reducing overall energy consumption while maintaining appropriate cleanliness levels in each zone.
Solution Approach 2:
Different clean production areas are equipped with return air systems tailored to their specific process requirements. Areas with higher cleanliness needs have more robust return air systems, while areas with lower requirements have simplified systems. This local quality approach ensures that each area receives the appropriate level of environmental control without over-engineering all areas to the highest standard, optimizing energy efficiency across the entire facility.
2Ease of operation
If partition walls are installed to separate clean production areas, then independent environmental control is achieved, but construction complexity increases
Solution Approach 1:
The partition walls serve multiple functions: they physically separate different clean production areas, provide mounting surfaces for return air passageways, and facilitate the creation of independent environmental zones. By integrating these multiple functions into a single structural element, the design reduces overall system complexity despite the added benefit of independent environmental control in each area.

Function Achieved in This Case
This approach reduces energy consumption and construction costs while ensuring precise environmental control for each process area, enhancing operational efficiency and product yield.
Implementation Method 1
dry cooling coils configured to cool circulating air are disposed between the lower technical interlayer and the first return air passageway as well as between the lower technical interlayer and the second return air passageway
Implementation Method 2
a side wall of each row of material storage rack is provided with a plurality of fan filter units configured to suck in an airflow in the third return air passageway and deliver the airflow into the corresponding material storage racks
Implementation Method 3
The fresh air supply pipe is provided with an electric regulating valve, and a temperature sensor is disposed in the material storage and transfer area or the third return air passageway. The control apparatus is in signal connection with the temperature sensor and the electric regulating valve, and is configured to control an opening degree of the electric regulating valve according to a temperature detected by the temperature sensor
