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, and a controller that adjusts fan operation and potentially introduces outdoor air or heating to maintain air temperature above surface temperature or dew point, preventing condensation by circulating and heating air as needed.
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 is insufficient
Solution Approach 1:
The system incorporates temperature sensors that continuously monitor surface temperature and air temperature, feeding this data back to a controller that adjusts fan operation in real-time. This closed-loop feedback mechanism enables the fan system to respond dynamically to temperature differentials and prevent condensation by maintaining appropriate air circulation patterns.
Solution Approach 2:
The fan system transitions from static operation to dynamic control, where fan speed and operation mode are continuously adjusted based on real-time temperature measurements. The controller modulates fan operation to maintain air temperature above dew point at critical surfaces, adapting circulation patterns to changing environmental conditions.
2Reliability
If fan operation is increased to prevent condensation, then condensation control is improved, but energy consumption increases
Solution Approach 1:
The system applies partial action by operating the fan at variable speeds rather than continuous high speed. The controller adjusts fan operation to provide just enough air circulation to maintain temperature differentials that prevent condensation, avoiding excessive energy consumption while ensuring adequate condensation control through sensor-triggered operation.
Solution Approach 2:
The system changes operational parameters dynamically by adjusting fan speed based on temperature measurements. Rather than maintaining constant high-speed operation, the fan speed is modulated according to the magnitude of temperature differentials and condensation risk, optimizing the balance between condensation prevention and energy efficiency.
3Reliability
If temperature monitoring and dynamic control are added to fan systems, then condensation control is improved, but device complexity increases
Solution Approach 1:
The system incorporates self-service capabilities through automated sensor-based control. Temperature sensors continuously monitor conditions and the controller automatically adjusts fan operation without requiring manual intervention or complex external control systems. This self-regulating approach improves condensation control while minimizing the added complexity by using straightforward sensor-controller-actuator architecture.

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.
