Transport Properties of Evaporative Cooling in a Seashell Packed Bed Cooling Tower

Abstract

This project was aimed to investigate the transport properties of evaporative cooling using seashell as packing material in a packed bed tower. Cockle shell was used as the packing material, which usually discharged as waste from marine life and fishery industry. The packing section is 15 inch high and filled with seashell which consists of 15 mm to 14 mm of equivalent diameter. The performance of cooling tower using seashell packing is compared to HDPE pipe packing. The results show that seashell packing have higher cooling water range, lower cooling approach and higher cooling tower efficiency than HDPE pipe packing. Meanwhile, cooling water range, R and cooling tower efficiency, e decrease with increasing of water to air ratio, L/G for all circulation rate. The heat transfer coefficient, KaV/L decreases with increasing of L/G ratio with lower circulation rate.
