ABSTRACT

Solar energy is clean source and endless reserves. Thus, putting Ihe device in order to

exploit this source of energy is of great significance, especially for countries with good sunshine

and radiation like Vietnam. In our country, the conventional solar stills are simple and low output

To enhance the yield of distilled water, the team has built up equipment distilled water using solar

energy with an area of 0,6 m- (evaporating area) couple wilh 8 evacuated glass tubes. Equipment

is tested in the sunny days in april in Ho Chi Minh city. Equipment has Ihe highest output when Ihe

brackish water depth is 0,01 m (6 liters) and the fresh water is 0,02 m (17,5 liters), production of

distilled water can reach 5,86 hters/m' (from 7am to 5 pm) lo Ihe average radiation 516 W/m'.

Keywords: Solar still; Evacuated glass tubes.
