How to Prevent Condensation in Radiant Cooling Systems

Preventing condensation is the most critical challenge in radiant cooling applications.

Unlike conventional air-conditioning systems, radiant cooling relies on surface temperature control rather than airflow, making dew point management essential.

Step 1: Monitor Indoor Dew Point in Real Time

The foundation of condensation prevention is accurate dew point monitoring.

This requires continuous measurement of both indoor temperature and relative humidity using reliable dew point sensors.

Step 2: Apply Dew Point-Based Control Logic

Effective radiant cooling systems do not rely on fixed temperature setpoints.

Instead, cooling output must be dynamically limited to ensure surface temperatures always remain above the calculated dew point.

Step 3: Independent Zone Control

Different rooms experience different humidity loads.

Independent zone control ensures that local dew point conditions are respected without compromising the performance of the entire system.

Step 4: Coordinate with Dehumidification Systems

Radiant cooling should be integrated with ventilation or dehumidification systems.

Lowering indoor humidity expands the safe operating range of underfloor cooling systems.

Step 5: Fail-Safe Protection Strategies

Advanced systems include alarm thresholds, automatic valve closure, and condensation risk indicators to protect floors and finishes.

Summary

Preventing condensation in radiant cooling systems is a control and integration task.

Reliable UFH and UFC projects depend on real-time dew point sensing, intelligent control logic, and coordinated system design.

Take Action to Prevent Condensation in Your Radiant Cooling System

Preventing condensation is not just a technical issue, but one that affects the long-term performance and comfort of your system. With real-time monitoring and intelligent control logic, you can ensure that your radiant cooling system runs efficiently while avoiding the risks of condensation.
