Abstract

In contrast to experimental testing, which is time-consuming and expensive, theoretical studies provide an economical and judicious methodology to evaluate the performance of desiccant dehumidifiers. Such approaches, developed based on the fundamental laws of thermodynamics, flow physics, and heat transfer, are critical to improving the dehumidifier design. This chapter firstly presents a general mathematical approach to predict the performance of DCHEs based on the governing principles of mass, momentum, energy, and species conservation. Next, the model is validated with the experimental results for different types of desiccants. Further, the validated model is employed to predict the performance of new fin-tube configurations. Detailed energy and economic analysis are then conducted on a hybrid central air-conditioning system comprising a composite superabsorbent polymer and mechanical vapor compression chillers. The hybrid configuration’s electrical power savings and its payback period are computed via this analysis. Lastly, the second law of thermodynamics is applied to study DCHEs and identify the causes of key irreversibility.
