Desiccant Cooling System Performance: A Simple Approach

Abstract

A simple algebraic model of wave motion arising in the adiabatic fixed-desiccant bed dehumidification of an air stream is applied to the prediction of the performance potential of a desiccant air conditioning system. The model is used to explain the increase in cooling system performance that has been realized through the use of mixed inert-desiccant material adsorption beds. The response of cooling system performance to changes in external process conditions is examined and conclusions are drawn relative to optimization of system characteristics.

Performance Evaluation of an Incorporation of a Compact Liquid Desiccant System Into an Evaporative Cooling-Assisted 100% Outdoor Air System

“…Under climate conditions where the temperature is high and the humidity is low, air conditioning can be achieved by EC [3,4]. The EC systems alone cannot provide optimal comfort for all climates, especially high humidity ones.…”

Analysis and Performance of Radial Flow Rotary Desiccant Dehumidifiers

“…Pseudo steady-state models and finite difference models have been developed and used to study the performance of the wheel at different parametric conditions; e.g., Holmberg (1979), Aly et al (1988), and Schultz and MitcheU (1989). More detailed work related to the performance of axial flow desiccant wheels is also given by Banks (1972a, b), Jurinak and Mitchefl (1984), , Epstein et al (1985), Van den Bulck et al (1986), Van den Bulck et al (1988), Kang and Maclaine-Cross (1989), Collier and Cohen (1991), Chant and Jeter (1995), and Zheng et al (1995).…”
