EVAPORATIVE COOLING IN A CLAY POT REFRIGERATOR:CFD SIMULATION AND EXPERIMENTAL VALIDATION
要約
Evaporative cooling is basically a passive cooling technique in which a body is cooled by the evaporation of
water from its surface.The paper deals with the two-dimensional unsteady mathematical model for a clay pot
refrigerator and validated with the experimental results obtained in the environment chamber.The test were
conducted at different relative humidity and dry bulb temperature and the test results were utilised to obtain
the pot efficiency,the COP and the variation of other parameters with the ambient conditions. The presence of
the porous medium as clay and sand were given a special importance for modelling the clay pot. The results
were also validated with numerical code developed indigenously for the above case. The effect of ambient
conditions on mass transfer coefficient, evaporation loss, hydraulic conductivity of clay and sand etc. were
studied and analysed.
