Abstract
Pot-in-pot cooling device is basically a food cooler that utilises the effect of evaporative cooling for its intrinsic mechanism to preserve drugs, fruits and vegetables in a hot and dry climate. The performance of the cooler was examined in this experiment when the lining media was changed from sand to charcoal and sawdust as well as considering the meteorological data of Ilorin. The cooling effects of three pots of the same geometry bearing different lining media were compared. The pots were set up and observed for 59 days from 8:00 am to 6:00 pm, and the performances were recorded. The device performs well under low relative humidity. The lining media that holds water necessary for evaporative cooling is the primary factor that was used to determine the performance of the pot-in-pot cooling device in this research. It was found that the three inner temperatures for the three lagging materials were significantly different. Under all three conditions, Charcoal (mean efficiency of 75 %) provides better results than sand (mean efficiency of 66 %) and sawdust (mean efficiency of 58 %).
