How Does Condensation Occur? The Science of Dew Point and Methods to Prevent Condensation in Electronic Equipment

Condensation is a common phenomenon in our daily lives, and it becomes a major concern when operating electronic equipment or designing cooling systems. In this article, we will explore why condensation occurs, the scientific principle of the dew point, the conditions that cause condensation, and practical methods to prevent it in electronic equipment. Condensation happens when water vapor in the air turns into liquid droplets on a cold surface. This does not occur just because the surface is cold — the air’s temperature and humidity play crucial roles. When these two values reach a certain point, the air can no longer hold moisture as vapor, and condensation begins. This critical temperature is known as the dew point .     The Principle of Dew Point and Condensation Formation The dew point is the temperature at which air at a specific humidity and temperature reaches full saturation and starts to condense water vapor. For example, at 24°C with 60% humidity...
