Tackling winter humidity issues can be a nightmare if you don’t have a grasp on the foundational principles that influence them. Have you ever wondered what causes some homes to be too dry even with a properly operating humidifier? Let’s look at some basic humidity principles, commonly encountered issues, and how you can solve them to cure your customers’ problems.
Relative humidity (RH) is a common term used to express the amount of moisture in the air as a percentage. Today’s test instruments calculate relative humidity using dry and wet bulb temperatures. If you’ve been around the industry for a while, you’ve probably twirled around a sling-psychrometer to obtain these readings. Newer instruments do this digitally — no twirling or distilled water are required.
