초록
In this study, we have carried out development and performance evaluation of optimized MEMS(Multi-Effect-Multi-Stage) fresh water generator with 7㎥/day for solar thermal desalination system. The developed MEMS was composed of high temperature part and low temperature part. This arrangement has the advantage of increasing the availability of solar thermal energy. The MEMS consists of 2 steam generators, 5 evaporators, and 1 condenser. Tubes of heat exchanger used for steam generators, evaporators and condenser were manufactured by corrugated tubes. The performance of the MEMS was tested through in-door experiments, using an electric heater as heat source. The experimental conditions for each parameters were 20℃ for sea water inlet temperature to condenser, 8.16㎥/hour sea water inlet volume flow rate, 70 ℃ for hot water inlet temperature to generator of high temperature part, 3.6 4.8, 6.0 ㎥/hour for hot water inlet volume flow rate. As a result, The developed MEMS was required about 85 kW heating source to produce 7㎥/day of fresh water. It was analyzed that the performance ratio of MEMS was about 2.6.
