A cost-effective technology that uses less energy for ventilation and doesn't contain chlorofluorocarbons (CFCs), the liquid desiccant system is seen as a practical alternative. Here, copper oxide nanoparticles were added to the solution in vitro together with a liquid calcium chloride desiccant to study the effectiveness of the dehumidification system. The flow rate and moisture content of the inlet air, as well as the flow rate and temperature of the desiccant solution, were evaluated for their influence on the operation of the dehumidification system. To gauge the degree of air dehumidification caused by the desiccant solution, a device was created and put to the test. MATLAB was used to carry out the mathematical modeling.
Copper oxide nanoparticles with a volume percentage of 0.35% and calcium chloride solution with a concentration of 48% by weight were utilized in the studies. The results of soluble dehumidification in both situations with and without nanoparticles showed that the dehumidification rate increased by an average of 5.2% and 6% for both experimental and modeling, respectively, when the nanoparticle content was increased.
