High-performance Adiabatic Desiccant Open-Cooling cycles
A new class of adiabatic desiccant open-cooling (ADOC) cycles has been identified in which the evaporative cooling is nearly reversible. With ideal components the thermal coefficients of performance (COP) at ARI room and ambient conditions can be more than double those of ADOC cycles previously investigated. Infinite COP's are shown to be physically possible for ADOC cycles but they are probably uneconomic. A COP of 2.0 may be economic but to determine this will require computer parametric and simulation studies with real components. The performance of commercially available cooling towers and regenerative dehumidifiers is much lower than that theoretically possible and considerable research and development is required.
