Title: Modeling and performance comparison of some non-conventional cooling and dehumidification options with a conventional cooling coil system

Conference ·
OSTI ID:163290

The use of a packed-type liquid desiccant absorber (PLDA) or an internally cooled liquid desiccant absorber (ICLDA) for air cooling and dehumidification show some promises over a water cooled cooling coil (WCCC) in terms of coolant temperature requirements and renewable energy applications. The purpose of this paper is to compare the performance of a PLDA, an ICLDA, and a WCCC with each other. For this purpose models to predict the performance of each system are developed and load removal characteristic plots are generated and presented in this work. As a case study, for two different sets of air inlet conditions depicting a high and a low latent and sensible load on each system, their cooling and dehumidification performance is reported as a function of coolant temperature and mass flow rate. Finally, for a given coolant temperature and mass flow rate, it was found that a PLDA and an ICLDA have better latent load removal characteristics while a WCCC showed better sensible load removal characteristics.
