Desiccant cooling: Parametric energy study

Building Services Engineering Research and Technology, 1998
Desiccants have been used in many applications to provide dehumidification. This paper describes an application of desiccants which provides both dehumidification and sensible cooling, with little or no use of conventional vapour-compression refrigeration plant. Through a parametric study, the energy consumption and costs of a desiccant cooling system

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

Desiccant aging and its effects on desiccant cooling system performance

Applied Thermal Engineering, 1996
Desiccants used for the purpose of space conditioning or enthalpy transfer can be subjected to hundreds of thousands of adsorption/regeneration cycles over their useful life. Studying the loss of a desiccant's equilibrium water adsorption capacity after exposure to thermal cycling is a common method for quantifying desiccant aging. Since isotherm shape

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.

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.

A hybrid solar desiccant cooling system

Solar Energy, 1985
Alternative methods of providing cooling using lower-grade energy have been investigated. This paper considers a cycle which combines indirect evaporative cooling with a dehumidifier to meet latent loads and a vapour compression refrigeration unit to meet sensible load.

Performance of Cross-Cooled Desiccant Dehumidifiers

Journal of Solar Energy Engineering, 1983
A cross-cooled silica gel desiccant dehumidifier model was designed, built, and tested. The performance of the unit was studied as a function of the inlet process stream dew point, process stream and cooling stream flow rates, and regeneration stream temperature and dew point. The tests were also simulated by a computer program and were compared to the

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.

Feasible study of a self-cooled solid desiccant cooling system based on desiccant coated heat exchanger

Applied Thermal Engineering, 2013
Abstract Solid desiccant cooling technology has become a research focus for its features of energy-saving and eco-friendly. However, widely adopted rotary desiccant wheel cooling system can't realize inner-cooling dehumidification process. In this paper, a novel self-cooled solid desiccant cooling system (SCDHE) is developed by integrating desiccant ...
