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

Abstract The issue of energy and environment is increasingly prominent, and air-conditioning system costs a lot of energy in the building. The liquid desiccant air-conditioning system is a novel air-conditioner with good energy saving potential, whose energy consumption mainly relies on the regeneration process of liquid desiccant.

Abstract Liquid desiccant cooling system is an energy-conservative and environment-friendly air-conditioning system. Its performance is strongly influenced by the thermal properties of liquid desiccant, especially the surface vapor pressure. Mixed liquid desiccant may have better dehumidification efficiency, lower material cost and lower energy ...

Liquid-desiccant systems simulation
International Journal of Refrigeration, 1992Abstract A mathematical model for a commercial liquid-desiccant system (Kathabar Spray-Cel System) was developed with necessary assumptions. The parameters in the system-describing equations were evaluated from information available in the literature. A Fortran code was written to solve the system-describing equations.

Thermodynamic analysis of liquid desiccants
Solar Energy, 1998Liquid desiccants are widely used in many solar applications. In order to analyze the performance of the system using desiccant technology, the thermophysical properties of desiccants are essential. In particular, the vapor pressure of the liquid desiccant is one of the important properties in air dehumidification.

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, 2016The 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 ...
