Dehumidification performance of liquid desiccant system with aqueous-CaCl2 solution in a humid climatic condition

The liquid desiccant solution can able to dehumidify the air by absorbing the water vapour content present in the air. The current work aims to test the dehumidification performance of liquid desiccant system with aqueous CaCl2 and ABS (Acrylonitrile butadiene styrene) packing in a humid climatic condition of India i.e., Kozhikode. The experimental setup is made with packed type dehumidifier. The dehumidification performance such as specific moisture removal, moisture removal rate and dehumidification effectiveness are studied with the effect of variation of solution flow rate, air flow rate, outdoor humidity ratio and solution temperature. The increase in solution flow rate and outdoor humidity ratio positively affect the dehumidification performance whereas the increase in solution temperature negatively affects the dehumidification performance. The increase in air flow rate increases the moisture removal rate but decreases the specific moisture removal and the effectiveness. The dehumidification performance shows a promising results, particularly performs better in higher outdoor humidity conditions. The dehumidification performance can be further improved by adding the cooling system.
