Liquid desiccant solution regeneration

Liquid desiccant air conditioning (LDAC) has emerged as an energy-saving process to provide thermal comfort to buildings. Unlike traditional vapor compression air conditioners, the LDAC process relies on concentrated liquid desiccant solution to regulate the air humidity and temperature.

In this study, a direct contact membrane distillation (DCMD) process of the LiCl liquid desiccant solution was simulated using MATLAB software. The simulation was first validated with the data obtained from experimental tests. Then, it was used to elucidate the feed and distillate temperatures, LiCl concentration, and water flux profiles along the membrane leaf inside the DCMD membrane module. Finally, with the help of the simulation, the effects of membrane properties and process operating conditions on the DCMD process performance were systematically examined.

An experimental investigation on the performance of a proposed hybrid desiccant based air conditioning system referred as HDBAC is introduced in this paper. HDBAC is mainly consisted of a liquid desiccant dehumidification unit integrated with a vapor compression system (VCS). The VCS unit has a cooling capacity of 5.27 kW and uses 134a as refrigerant. Calcium chloride (CaCl2) solution is used as the working desiccant material. HDBAC system is used to serve low sensible heat factor applications.
