Study of Liquid Desiccant Air-Conditioning for High Performance Greenhouses
… high cooling loads experienced by a greenhouse. Liquid desiccant air-conditioning (LDAC) have been found to provide high latent cooling capacities, which is perfect for the application of a humid greenhouse microclimate. TRNSYS simulations were undertaken to study the feasibility of two liquid …

Analysis of a Flat-Plate, Liquid-Desiccant, Dehumidifier and Regenerator
… for isothermal and non-isothermal flat-plate liquid-desiccant dehumidifiers and regenerators was developed and implemented. The two-dimensional model takes into account the desiccant, water and air flow streams. A parametric analysis was performed to evaluate the influence of some of the most …

Evaluation of Heat Rejection Strategies for Liquid Desiccant Air-Conditioning Systems
… heat. One promising technology is the use of a Liquid Desiccant Air-Conditioning (LDAC). An evaporative cooling tower (ECT) was used as a cooling device to reject the heat from a LDAC at Queen’s University. Investigation of the ECT showed significant power consumption and ineffective operation …

Design and development of a novel liquid desiccant air-conditioning system
… Loop (DECAL) system is a novel high efficiency liquid desiccant air-conditioning (LDAC) system which runs primarily on thermal energy rather than electricity. It is designed for residential cooling in hot and humid climates where demand is growing rapidly and incumbent direct-expansion system …

Selection of the liquid desiccant in a run-around membrane energy exchanger
In this thesis, several possible liquid desiccants (aqueous solutions of LiCl, LiBr, MgCl2 and CaCl2) are investigated to find the most appropriate working fluid to be used in a run-around membrane energy exchanger (RAMEE). The liquid desiccant is one of the main components of the RAMEE and …

Development, analysis and performance assessment of net zero energy house systems.
… house, while solar panels power absorption and liquid desiccant systems which provide air-conditioning and fresh water. Hot water is produced by solar heat, photovoltaic thermal system (PV/T) and from a ground thermal storage, where hot water from solar panels passes through during the long …

Design and performance testing of a novel ceiling panel for simultaneous heat and moisture transfer to moderate indoor temperature and relative humidity
… in design to a radiant ceiling panel, but uses a liquid desiccant as the heat and moisture transfer medium and the surface of the panel is made of a semi-permeable membrane. A HAMP can be installed into a space and heat and moisture will be transferred between the liquid desiccant and the space …

EXPERIMENTAL CHARACTERIZATION OF CRYSTALLIZATION FOULING IN LIQUID-TO-AIR MEMBRANE ENERGY EXCHANGERS
Liquid-to-air membrane energy exchangers (LAMEEs) are a recent development with potential for energy savings in heating, ventilation and air-conditioning (HVAC) applications. Unlike conventional heat exchangers that transfer only heat using plates or tubes, LAMEEs use semi-permeable membranes to …

MODELLING CRYSTALLIZATION FOULING IN LIQUID-TO-AIR MEMBRANE ENERGY EXCHANGERS
… to separate water from an aqueous solution. Liquid-to-air membrane energy exchangers (LAMEEs) use membranes to control humidity and temperature in heating, ventilation and air-conditioning (HVAC) systems. A semi-permeable hydrophobic membrane is used in LAMEEs to separate an air stream from …
