Design And Development Of a Model Refrigerator For Ice Block Production
Keywords:
Coefficient of Performance, Compressor, Condenser, Rectangular Chamber, Heat TransferAbstract
The ambient temperature of tropical countries like Nigeria is as high as 40°C during the dry season. This ultimately gives rise to increase in demand for ice which is used to reduce the temperature of water, soft-drinks as well as other storage uses. This increase in demand for ice block makes this project a worthwhile venture. In order to achieve quick freezing, certain design considerations, such as the quantity of water to be frozen, the choice of cooling system and the methodology of attaining the desired result were discussed. The design methodology adopted in this project involves a study on the possibility of increasing the area of heat transfer and employing a refrigerating system to generate the effect that can result to the formation of ice block, using a rectangular chamber of external mild steel framework and internal aluminum material with assembled compressor and condenser units. The coefficient of performance(COP) of the Ice block refrigeration process is 2.26
