Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensation on surfaces in indoor areas leads to issues like dampness, mold growth, and corrosion, particularly in unconditioned spaces or those with high humidity, where existing fan systems fail to effectively prevent its formation.
Innovation Solution
A system comprising a fan, sensors for surface and air temperature, relative humidity, and a controller that adjusts fan operation and potentially introduces outdoor air or heating to prevent condensation by predicting and mitigating dew point conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fan system is used to circulate air in unconditioned spaces, then air circulation is improved, but condensation control capability deteriorates because the fan cannot prevent condensation formation on surfaces
Solution Approach 1:
The system performs preliminary action by continuously monitoring surface temperature and air conditions to predict condensation events before they occur. When the surface temperature approaches the dew point, the controller activates the fan to circulate air and prevent condensation formation, rather than waiting for condensation to actually form.
Solution Approach 2:
The system implements feedback control by using sensors to continuously monitor surface temperature, air temperature, and relative humidity. The controller processes this feedback information to determine when condensation is likely to occur and adjusts fan operation accordingly, creating a closed-loop control system that adapts to changing environmental conditions.
2Speed
If existing fan systems operate continuously to circulate air, then air circulation is improved, but energy consumption increases without effectively preventing condensation
Solution Approach 1:
The system applies dynamics by transitioning the fan from continuous operation to variable/conditional operation. The fan speed and operation duration are dynamically adjusted based on real-time environmental conditions monitored by sensors, allowing the system to optimize energy consumption while maintaining effective condensation control when needed.
Solution Approach 2:
The system changes operational parameters (fan speed, operation timing) based on environmental parameter changes. When temperature and humidity conditions indicate low condensation risk, the fan operates at reduced speed or remains off, thereby reducing energy consumption while maintaining condensation prevention capability when conditions deteriorate.
3Device complexity
If no condensation control system is installed in unconditioned spaces, then device complexity is reduced, but surface degradation from condensation increases
Solution Approach 1:
The system implements self-service by using the existing fan infrastructure and adding only the necessary control components (sensors and controller). The fan serves dual purposes: its original air circulation function plus the new condensation control function, eliminating the need for completely separate condensation prevention equipment and reducing overall system complexity.

AI summary
A system and related method are disclosed for controlling condensation in a space. The system includes a fan and one or more sensors for sensing environmental conditions such as temperature and relative humidity associated with the space and/or objects within the space. For instance, the sensors may sense a surface temperature of an object within the room. The system also includes a controller capable of receiving measurements from the sensor(s) and controlling the fan based on the sensed information. The system may additionally include a heater and/or a damper for transferring outside air into the space, either of which may be controlled by the controller based on the measurements.
