Adiabatic Spray Humidification Systems in Telecommunications Facilities

This paper describes the economic and operating advantages of using adiabatic spray humidification systems in Telecommunication Buildings. In addition to providing the humidification requirements for the communications equipment, a stand-alone spray humidification system provides a significant evaporative cooling effect in dry climates. In cold climates where the use of all air cooling systems is commonplace, the evaporative cooling effect reduces the large amounts of outside air used and the associated humidification load. Experimental results obtained to evaluate the effect of spray nozzle design, air flow and wet filter media characteristics are presented. In addition, a stand-alone spray humidification unit presently being used in the AGT system, is examined.
