Energy efficient strategies for improved dehumidification
A recent article by William L. McGrath on future trends in HVAC design indicated that {open_quotes}the most profound change in our technology will be in the direction of improving functional performance{hor_ellipsis}{close_quotes} specifically improved humidity control. Increased outdoor ventilation rates due to implementation of ASHRAE Standard 62-1989, and the realization of the need to maintain relative humidities between 30 and 60% indoors for improved indoor air quality, will likely drive improvements and wider Application of humidity control in HVAC systems. This is especially true in hot and humid climates where a lack of proper dehumidification can result in unacceptable comfort levels and microbial growth on interior building surfaces. Although not commonly applied, many options to improve dehumidification control do exist. This paper discusses options including fan cycling strategies, coil temperature adjustment, heat pipe heat exchangers, and desiccant air-conditioning.
