Fume Hood Sash Window Detection for Energy Loss Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fume hoods in laboratories and production facilities often consume excess energy due to inadvertently left-open sash windows, leading to inefficient ventilation unit operation and energy wastage.
Innovation Solution
A system that includes a detection unit to monitor the open state of a fume hood sash window and user presence, alerting users when the window is left open for extended periods, and calculating energy loss to optimize energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ventilation unit operates continuously to ensure toxic fumes are exhausted, then safety is improved, but energy consumption increases
Solution Approach 1:
The system uses sensors to detect sash window position and user presence, then provides feedback through notifications to users about energy consumption. This feedback loop encourages users to close sash windows when not in use, reducing unnecessary ventilation operation and energy consumption while maintaining safety during actual use
Solution Approach 2:
The system automatically monitors sash window position and user presence without requiring manual input, and automatically calculates and communicates energy consumption data. This self-monitoring and self-reporting capability reduces the need for continuous manual oversight while optimizing energy usage
2Ease of operation
If the sash window is left open for easy access to chemicals, then ease of operation is improved, but energy wastage increases
Solution Approach 1:
The system proactively notifies users about open sash windows and associated energy consumption before significant energy wastage occurs. By providing timely alerts, users are prompted to close sash windows during non-use periods, preventing energy loss while maintaining easy access during actual work
Solution Approach 2:
The system changes the operational parameters of the ventilation unit based on detected sash window position and user presence. When the sash is closed and no user is detected, the ventilation operation is reduced or stopped, thereby changing energy consumption parameters to match actual usage needs

AI summary
A system to optimize energy usage associated with a fume hood is disclosed. The system may include a transceiver and a processor. The transceiver may be configured to receive inputs from a detection unit. The processor may obtain the inputs from the transceiver. Responsive to obtaining the inputs, the processor may determine that an extent of open state of a window associated with an enclosure may be greater than a predefined threshold for a predefined time duration and an absence of a user in proximity to the enclosure for the predefined time duration based on the inputs. The processor may further determine a total time duration the extent of open state is greater than the predefined threshold. Furthermore, the processor may calculate an estimated energy loss associated with the enclosure based on the extent of open state and the total time duration, and then output the estimated energy loss.
