Recent progress on desiccant materials for solid desiccant cooling systems

Energy, 2014
Abstract SDC (Solid desiccant cooling) systems have gained increasing interest as an alternative air conditioning technology. Performance of desiccant plays a crucial role in overall performance of the whole system, especially in terms of dehumidification and regeneration capacity.

Desiccant cooling air conditioning: a review

Renewable and Sustainable Energy Reviews, 2006
In this paper, the principles underlying the operation of desiccant cooling systems are recalled and their actual technological applications are discussed. Through a literature review, the feasibility of the desiccant cooling in different climates is proven and the advantages it can offer in terms energy and cost savings are underscored. Some commented

Development of Membrane-Based Desiccant Fiber for Vacuum Desiccant Cooling

ACS Applied Materials & Interfaces, 2016
A novel hydrophobic membrane-based desiccant fiber (MDF) was developed by loading lithium chloride into hydrophobic hollow fiber membranes. The MDF thus made was then tested for vapor absorption under controlled conditions. Furthermore, an MDF pad, which was made by weaving MDF into a piece of garment, was built into a laboratory vacuum desiccant ...

Passive Cooling of Photovoltaics with Desiccants

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
As part of efforts to reduce photovoltaic (PV) costs and improve reliability/durability, temperature control needs to be closely examined in a number of ways including novel passive cooling technology. Modest PV module operating temperature reductions can increase PV power output by 100% or more.

An Alternative Desiccant Cooling Cycle

Journal of Solar Energy Engineering, 1995
A computer analysis of the thermal performance of a desiccant cooling cycle in which the cooled air, passing to the space to be conditioned, has not been in contact with the desiccant. It is shown that an important factor is the efficiency of the desiccant tower. Only liquid desiccants are considered.

IMPROVEMENTS IN SOLID DESICCANT COOLING

Drying Technology, 1993
ABSTRACT The DINC (Direct-Indirect Evaporative Cooling) cycle was proposed in 1986 by Texas A6H researchers. The idea wae to combine the benefits of direct and indirect evaporative cooling with desiccant dehumidifying using a rotating aolid silica-gel dehumidifier. Recent parametric studies completed for the Texas Energy Ramarch In Applications Program

A Review of Desiccant Cooling Systems

Journal of Energy Resources Technology, 1993
This paper describes recent published design advances that have been made in desiccant cooling systems. In desiccant cooling cycles, the desiccant reduces the humidity of the air by removing moisture from the air. Then the temperature is reduced by other components such as heat exchangers, evaporative coolers, or conventional cooling coils.

Desiccant Degradation in Desiccant Cooling Systems: A System Study

Journal of Solar Energy Engineering, 1993
We predicted the impact of desiccant degradation on the performance of an open-cycle desiccant cooling system in ventilation mode using the degradation data on silica gel obtained from a previous study. The degradation data were based on thermal cycling desiccant samples and exposing them to ambient or contaminated air.

Desiccant Degradation in Desiccant Cooling Systems: An Experimental Study

Journal of Solar Energy Engineering, 1993
We conducted experiments to quantify the effects of thermal cycling and exposure to contamination on solid desiccant materials that may be used in desiccant cooling systems. The source of contamination was cigarette smoke, which is considered one of the worst pollutants in building cooling applications.
