【 摘 要 】

Speed up in vacuum desalination system means many things that are in desperate need of development especially energy transfer. Therefore, in this experiment, a pump is used to transfer the energy from the solar collector into the evaporator including the forced convection heat transfer. The water fluid inside the solar collector is heated by sunlight and then pumped into the evaporator to evaporate seawater. It is done to support the performance of the condenser which turns steam into clean water. It is reported that pump performance for a total head loss value is 2.67 m and for pump head is 2.82 m. By generating pump axle power of 28.73 W, thus the resulted motor power was 33.03 W. With total existing energy for 13 MJ/m2 the electric current generated by solar cell during experiment is 2.6 A in average from 08.00 A.M until 16.00 P.M with speed water average of 3.1 m/s. It is due to the effect of the sun intensity if the sun intensity is high speed of the pump is also high since it uses a photovoltaic 100 WP therefore it affects the electric current received by the pump.
