Hybrid Desiccant Cooling Systems
HVAC systems that use heat-regenerated desiccant wheels to remove moisture can be energy-efficient alternatives to traditional systems. Site-specific conditions and differing application requirements must be understood and quantified before desiccant-assisted hybrid systems can be justified on economic grounds. Although a detailed analysis is generally required, a few key variables drive costs and benefits. When two or more of these key variables favor a hybrid system over a conventional system, then a detailed analysis of the benefits vs. costs of a hybrid desiccant system is appropriate.Units: DualCitation: ASHRAE Journal, vol. 49, no. 1, January 2007
