Abstract

This paper focuses on desiccant wheel (DW) energy analysis. Numerical modeling is developed for the DW which is the key component of desiccant cooling systems. The mathematical model is validated by experimental results. In this paper, energy effectivenesses of DW are studied as well as energy consumption. An energy relation is developed and used to calculate DW power consumption, which is consisted of both DW drive power consumption and regeneration heat. Trends of energy effectivenesses of DW are presented in the various regeneration temperatures and DW speeds. An energy term is defined by dividing total power consumption to the adsorbed water rate and introduced as “specific adsorption energy (SAE)”. In addition to specific adsorption energy trends in the various regeneration temperatures and DW speeds, Genetic algorithm is used to find the minimmal point of SAE in the range of operating variables. The optimization results show that in the regeneration temperature of 61.9 \(^{\circ }\)C and rotation DW speed of 21.2 (Rph), minimmal SAE of DW is achieved.
