Effect of cooling water profile on coefficient of performance of split type Air- conditioning system
MetadataShow full item record
The purpose of this research was to investigate cooling water profile that effect to coefficient of performance of spilt type air- conditioning system. Air conditioner size of 12,000 Btu/h was used in this experiment. There are three experiment of cooling water profiles in this work such as water spray, water drop and heat exchanger profile. The ambient temperature conditions were controlled at 35, 40, 43 and 45 oC. The results of this study were found that heat exchanger profile had the highest average coefficient of performance and energy efficiency as 4.94 and 9.15 Btu/Wh which increased as 20.1% and 8.47% respectively when comparing with the normal working.
