Progress in selecting desiccant and dehumidifier for liquid desiccant cooling system

Energy and Buildings, 2012
Abstract Liquid desiccant cooling system (LDCS) is an alternative air-conditioning system with good energy-saving potential. Dehumidification performance is the key part of LDCS; while desiccant variety and dehumidifier influence the dehumidification performance.

Modeling and parametrical analysis on internally-heated liquid desiccant regenerator in liquid desiccant air conditioning

Energy, 2017
Abstract In this paper, the mathematical models of pre-heated and internally-heated liquid desiccant regenerator are established including parallel flow, counter flow and cross flow with two kinds of different flow directions of heated water respectively. Simulation results reflect that regeneration performances of the internally-heated are about 2–4

Dynamic modeling of a liquid desiccant dehumidifier

Applied Energy, 2016
The liquid desiccant dehumidification system is becoming a hotspot in air dehumidification due to its promising prospects. Many models have been reported in the literature, but they are rarely applicable to control design due to various reasons. In this paper, a simplified dynamic model of liquid desiccant dehumidifier is proposed from a control point ...

Application of Liquid Desiccant System

2013
Liquid desiccant air-conditioning systems have developed quickly in recent years in China. Processed air can be dehumidified and cooled in summer, and humidified and heated in winter using liquid desiccant. Low-grade heat can be utilized to regenerate liquid desiccant, such as exhaust heat from condenser of heat pump, hot water. The operating principle

Design of ionic liquids as a desiccant for the liquid desiccant type air conditioning system

Chemistry Letters
Abstract Recently, liquid desiccant air conditioners (LDACs) have gained rapidly growing interest as an important candidate for an energy-efficient air conditioner. By enabling moisture absorption from the air, ionic liquids (ILs) can serve as a novel desiccant source for LDACs.

Design and Testing of a Liquid Desiccant Dehumidifier

Transactions of the ASAE, 1984
ABSTRACT A dehumidification system employing liquid desiccant was designed, constructed, and tested to determine the effect desiccant and air temperatures have on water vapor absorption rate. Calcium chloride desiccant was used for experimentation. A linear mathematical equation expressing concentration and concentration ratio as a function of time ...

Gas-powered liquid desiccant dehumidifier

Applied Energy, 1993
Abstract A novel concept for the operation of a liquid desiccant domestic-dehumidifier has been proposed: the resulting developed system dehumidifies air by passing it directly over a liquid desiccant. The system is novel in two respects: first, a bubble pump is used to both reconcentrate the desiccant as well as pump it around the system; secondly ...

Liquid Desiccant Air-Conditioning Systems

2020
The liquid desiccant air-conditioning system has been identified as a promising technology that has the potential of decoupling and preciously controlling the latent and sensible cooling loads of air-conditioning spaces. The issues of moulds and bacteria growth on the wet surface of chilled water coils of conventional air handling units can be resolved

On the weight of hydrogen desiccated by liquid air

Proceedings of the Royal Society of London, 1900
Abstract In recent experiments by myself and by others upon the density of hydrogen, the gas has always been dried by means of phosphoric anhydride; and a doubt may remain whether on the one hand the removal of aqueous vapour is sufficiently complete, and on the other whether some new impurity may not be introduced.

Performance Comparison of Enthalpy Recovery Devices Using Liquid Desiccant and Desiccant Wheel

Journal of Thermal Science and Engineering Applications, 2020
Abstract Heat recovery between outdoor air and indoor exhaust air is an effective approach for energy-saving in the air-conditioning system. Performances of enthalpy recovery devices using liquid desiccant (LD) and desiccant wheel (DW) are compared in the present study.
