Experimental investigation for performance enhancement of a vapor compression refrigeration system by employing several types of water-cooled condenser

The water-cooled condenser in vapor compression refrigeration system is used in regions where there is a humid subtropical climate and where air-cooled condensers are not much effective. In the current article, the authors have scrutinized various means by which coefficient of performance can be escalated by using various types of water-cooled condensers. The setup has six different arrangements and the experiment is conducted at three ambient temperatures viz. 28 degrees C, 32 degrees C, 36 degrees C. There is an increment in the value of coefficient of performance with better arrangements, the percentage variation of coefficient of performance at 36 degrees C starting from chilled water circulated condenser, condenser with induced cooling tower, condenser with forced cooling tower, condenser with single cellulose pad, condenser with double cellulose pads are as follows: 12.33%, 14.43%, 18.37%, 24.41%, and 29.13%, respectively, with respect to the simple water-cooled condenser whose coefficient of performance is 3.81 at 36 degrees C. More improvements can be expected if materials of high heat transfer coefficient are used.
