Maintaining Space Temperature and Humidity in the Digital Switch Environment
MetadataShow full item record
A methodology for a psychrometric analysis of the problem of maintaining space temperature and humidity in the digital switch environment is presented. Such spaces produce minimum or no humidity generation. Several different humidification schemes, including isothermal (steam generation) and adiabatic (evaporative cooling) were analyzed. In some cases, the addition of a steam humidifier to an air handling system with an outside air economizer cycle was seen to require more energy than running the same system on minimal outside air with mechanical refrigeration and substantially lower moisture load. Because individual locations will have different operational parameters, this sort of analysis is done by the design engineer as a tool in selection and design of an appropriate humidification system.
