Abstract
he performance of a double effect solar distillation unit
incorporating a paraffin wax has been studied experimentally under the climatic
conditions of Owerri, South-East Nigeria. The system comprises double basins
with an absorber area of 1.10m2 and a saline water storage tank. It was
positioned in the North-South direction with both upper and lower glazings
inclined at the latitude of the study location. Performance evaluation of the
system was conducted for an extended period of time, capturing both diurnal and
nocturnal phases of the system’s operation. The hourly distillate yields of the
upper and lower basins were compared. The lower basin performed better than
the upper basin during diurnal phase. The diurnal distillate yield of the system
ranged from 0.415L to 0.741L for the lower basin and zero to 0.025L for the
upper basin. The system achieved a maximum distillate yield rate of 0.21 L/h and
an average efficiency of 11.71%.
