Developing of a novel water-efficient configuration for shower cooling tower integrated with the liquid desiccant cooling system

Abstract

A novel configuration of shower cooling tower (SCT) with counter-current flow pattern and a liquid desiccant system equipped with the internal cooling system, used lithium chloride as an adsorbent, is developed and modeled separately and mathematically. The governing relations are solved numerically using a finite difference scheme, and the performance of the hybrid system is parametrically studied. The precision of numerical modeling is increased considering the air humidity impact on the air temperature changes during the moisture absorbing and changes in the diameter of the water droplets along the SCT. A novel configuration is developed by the combination of an SCT and a liquid desiccant system as a hybrid system, and the influences of geometric, physical and environmental parameters on the efficiency of the system are scrutinized. The results show that when the initial diameter of water drops is decreased, the temperature of outlet water reduces; whereas, using the hybrid system reduces the process water temperature up to about 32 °C and 37 °C with and without dehumidifier system at 10 m height of shower cooling tower. In hot and humid regions, reducing the process water temperature of shower cooling tower utilized in the hybrid system is greater compared to a single cooling tower.
