Abstract
The cooling system is an essential part of the production process within the plant. In the cooling system using cooling tower, efficiency can be improved by increasing the effectiveness of cooling through nozzle modification. This study aims to determine the effect of diameter and number of nozzle holes on cooling effectiveness. The data were taken from the experiments using prototype of counterflow cooling tower with dimension of high x cross-sectional area are 120 cm x 40 cm x 40 cm. Diameter varied by 1; 1.5; and 2 mm, while the number of nozzle holes 4; 8; 16. The results show that the highest cooling effectiveness was achieved at nozzle diameter 1.5 mm with the number of holes 8 that is 38.77%.
Highlights
Developments in technology are growing rapidly, industry needs continue to grow, industries need efficient tools to facilitate production activities, especially for industries involved for both thermal power plants and air conditioning industry [1, 2]
Zein et al [4] recommends that condenser performance can be significantly improved by increasing the diameter of the full conical GCZ nozzle and installing a fine wire on the Cooling Towers (CT) exit display screen
The cooling tower effectiveness is the ratio between the range of the device and the ideal range, where the ideal range is the difference between the cooling inlet temperature and ambient wet bulb temperature
Summary
Developments in technology are growing rapidly, industry needs continue to grow, industries need efficient tools to facilitate production activities, especially for industries involved for both thermal power plants and air conditioning industry [1, 2]. Such industries require cooling towers for cooling [3]. The average cooling water flow increased by about 3.5%. Improved condenser performance increases the average power generation by about 1 to 2 MW in Wayang Windu Geothermal Power Plant, West Java, Indonesia. Air and water flow may be opposite, cross-flow or both [8]
