Abstract Distributed operating of Liquid Desiccant Dehumidification System (LDDS) increases the flexibility in system operation, allowing one regenerator to handle multiple dehumidifier units. To meet the requirement of this operating scheme, a soft-sensor is developed for the real-time measurement of the desiccant solution concentration.

Performance optimization of heat pump driven liquid desiccant dehumidification systems
Energy and Buildings, 2012Heat pump driven liquid desiccant dehumidification (HPLD) devices, in which both the cooling capacity from an evaporator and heat from a condenser are utilized, have been developing rapidly in recent years. Because the amount of heat from the condenser is usually more than required for desiccant regeneration, the key to improve the performance of these

Formaldehyde removal performance analysis of a liquid desiccant dehumidification system
Building and Environment, 2017Abstract Liquid desiccant (LD) systems are an efficient method for humidity control. Moreover, LD systems also function to purify the air and remove volatile organic compounds such as formaldehyde. This study aims to analyze the performance of a LD system for formaldehyde removal from indoor air while simultaneously considering air dehumidification ...

Researches and trends in membrane-based liquid desiccant air dehumidification
Renewable and Sustainable Energy Reviews, 2013Abstract Membranes were used in combination to liquid desiccant air dehumidification to separate the liquid desiccant from the process air to prevent the problems of liquid droplets crossover. In this review, the developments in this relatively new technology were introduced.

A simplified model for air dehumidification with liquid desiccant
Solar Energy, 2004This paper describes a relatively simple model for the preliminary design of an air dehumidification process occurring in a packed bed using liquid desiccant through dimensionless vapor pressure and temperature difference ratios. An expression is derived using the aforementioned ratios to predict the water condensation rate from the air to the ...

Experimental study of dynamic characteristics of liquid desiccant dehumidification processes
Science and Technology for the Built Environment, 2016Liquid desiccant dehumidification is an effective method of removing moisture from the air for air conditioning in built environments. The dehumidifier is a critical component where coupled heat and mass transfer between the desiccant solution and the air occurs.
