1. What is Condensation Risk?

Condensation risk occurs when surface temperature falls below the dew point temperature, causing moisture in the air to condense on surfaces. This can lead to mold growth, structural damage, and indoor air quality issues.

2. How Does the Calculator Work?

The calculator uses the condensation risk formula:

Where:

• \( T_{surface} \) — Surface temperature (°C)
• \( T_{dew} \) — Dew point temperature (°C)

Explanation: When surface temperature is lower than dew point temperature, condensation occurs. The calculator evaluates this condition and returns "Yes" if risk exists, "No" if no risk.

3. Importance of Condensation Risk Assessment

Details: Assessing condensation risk is crucial for building design, HVAC system planning, moisture control, and preventing mold growth and structural deterioration in buildings.

4. Using the Calculator

Tips: Enter surface temperature and dew point temperature in degrees Celsius. Both values must be valid numerical inputs. The calculator will determine if condensation risk exists.

5. Frequently Asked Questions (FAQ)

Q1: What is dew point temperature?
A: Dew point is the temperature at which air becomes saturated with moisture and condensation begins to form.

Q2: When is condensation risk highest?
A: Risk is highest when warm, humid air contacts cold surfaces, typically in poorly insulated areas or during temperature transitions.

Q3: How can I reduce condensation risk?
A: Improve insulation, increase ventilation, use dehumidifiers, and maintain proper indoor temperature control.

Q4: What surfaces are most vulnerable?
A: Windows, exterior walls, corners, and areas with poor insulation or thermal bridging are most susceptible to condensation.

Q5: Is condensation always problematic?
A: Occasional minor condensation may not be harmful, but persistent condensation can lead to mold, mildew, and structural damage over time.
