Abstract
this study is dealing with the characteristics and performance of the ~e of evaporative condenser in refrigerating units.
A simple analytical method, based on the method of Parker and Treybal (1961) for evaporative coolers, was developed to predict the performance of evaporative condensers. The transfer coefficients of the model were predicted from standard correlations in the literature or those determined by Parker and Treybal for evaporative coolers. This work presents a description of a computer algorithm developed to perform rating calculatipns of evaporative condenser. Also illustrates the various simulations that are possible, including varying wet bulb inlet temperature, different air and water mass flow rates, condensing temperature of refrigerant and condenser capacity.
It is shown that the performance of the evaporative condenser can be predicted by using of the computer program.
An experimental set-up was used for this investigation. A refrigerating ice-making plant equipped with evaporative condenser is used to carry out the experimental work.
Field tests were performed on an evaporative condenser and the measured and predicted re circulating water temperature and number of transfer unit available and required.
the predicted water temperature is lower than the ;$’ to 1 ’C , also the number of transfer units available are required by 0.1 to 0.2 .
both the predict values of the overall heat transfer by a factor of 2.25 and the overall mass transfer Ka by a factor of 1.4 gives a fairly good agreement between red and predicted values of the recicu/aing water temperature number oftransferunits.
