dc.description.abstractThis paper deals with the development of a simple mathematical model for experimental validation of the performance of a small evaporative cooling system in a tropical climate. It also presented the coefficient of convective heat transfer of wide range of temperatures based on existing model. Extensive experiments have been performed during January to February 2013 for a small evaporative cooler designed for storage of fruits and vegetables. The model considered the thermal properties of the material of the cooling pad and assumed that the cooling pad is a plain porous wall bounded by two convective airs at different temperature at the two surfaces. The predicted and experimental value of various cooling efficiency at different range of inlet temperature has been determined. In addition the values of the coefficient of convective heat transfer for a wide range of temperatures is also presented.en
dc.description.abstractOvaj rad se bavi razvojem jednostavnog matematičkog modela za eksperimentalnu ocenu performansi malog evaporativnog rashladnog sistema u tropskim klimatskim uslovima. Predstavljen je i koeficijent konvektivnog prenosa toplote velikog opsega temperature na osnovu postojećeg modela. Obimni eksperimenti su izvođeni tokom januara i februara 2013 sa malim evaporativnim uređajem za hlađenje skladišta za voće i povrće. Model je uzeo u razmatranje termičke osobine materijala rashladnog sloja i pretpostavio da je rashladni sloj ravan porozni zid ograničen sa dva konvektivna sloja vazduha na različitim temperaturama na obe granične površine. Određene su izračunate i eksperimentalne vrednosti različitih efikasnosti hlađenja pri različitim opsezima ulaznih temperature. Uz to, predstavljene su i vrednosti koeficijenata konvektivnog prenosa toplote za veliki opseg temperatura.sr
