There is a lot of buzz these days about desiccant dehumidification systems: Where should they be applied? How should they be specified and designed? In the first of two parts, the author finds that after talking with the experts, the answers to such questions can still be a little murky.
The type of water used - potable, softened, high-purity, or boiler water - affects a humidification system's performance, vapor quality, and efficiency. Know the differences in order to choose the best solution for a specific application's needs.
Ensuring adequate humidity is seen increasingly as another way to maintain worker productivity. The author examines one type of humidification system, how it should be engineered for optimum efficiency, and some of the challenges involved with incorporating it into an existing hvac system.
