Last week, we reviewed different types of steam humidifier distribution methods, which are inexpensive but have longer absorption distances. Many HVAC installations require very short... READ MORE

In humidification systems, we know that steam absorption distance is important. We also know that various distribution methods have different required absorption distances. How do... READ MORE

In the last couple Monday Morning Minutes, we showed how the type of humidifier dispersion method could affect the absorption distance. Let’s look at an example. Ex: 5000 CFM at 55OF Duct temperature to provide a room RH at 35% at 70OF with 50% outside air. [Read more…]... READ MORE

Absorption or non-wetting distance is the dimension downstream from the leaving side of the steam dispersion assembly to the point where wetting will not occur, although wisps of steam may be present. Solid objects at duct air temperature, such as coils, dampers, fans, etc., downstream of this dimension will remain dry. Location A is the best choice. [Read more…]... READ MORE

Duct or AHU temperature. Cool air absorbs less than warm air and requires a longer absorption distance. When equal amounts of steam are introduced into equivalent ducts but with different air temperatures, the lower temperature systems of 50 °F to 55 °F are more difficult to ensure absorption than systems with higher temperatures.
