An open-cycle desiccant system
dehumidifies and cools air directly, providing greater efficiency
and less pollution.
REGULATORY ISSUES ARE fundamentally changing the heating, ventilation, and air-conditioning (HVAC) market. Growing concerns about indoor air quality the phase-out of traditional refrigerants, and renewed emphasis on energy efficiency threaten the future of traditional vapor-compression refrigeration cycles.
The air conditioner of the future will have to efficiently provide increased amounts of ventilation air, avoid the use of chlorofluorocarbons or similar compounds, provide cool unsaturated air below 70-percent relative humidity, maintain relative humidity in the ...
