PURPOSE: A method for operating a desalinating apparatus is provided to obtain a desalinated water from raw water such as salt composing underground water and industrial waste water by using solar energy. CONSTITUTION: A desalination apparatus utilizing solar energy, and a method of operating the same. This apparatus is provided with a solar heat collector (12) for heating a heating medium (13) with solar energy, a heat exchanger (92) cooperating with an evaporation can (60) so as to subject the heating medium and raw water (62) in the evaporation can to heat exchange and generate water vapor (63) therein, a condenser (98) cooperating with a raw water tank (72) so as to receive the vapor (63) from the evaporation can, cool the vapor by subjecting the vapor and raw water in the raw water tank to heat exchange and obtain distilled water, a distilled water tank for storing distilled water, an evacuating means for evacuating the evaporation can and depressurizing the inside so as to promote the generation of vapor in the evaporation can, and a means for supplying raw water to the evaporation can. When a plurality of evaporation cans (60) are provided, a condenser cooperating with the evaporation cans is provided so as to receive the vapor (63) from an upstream-side evaporation can, cool the vapor with the raw water in a downstream-side evaporation can and thereby produce distilled water, and also heat the raw water in the downstream-side evaporation can and generate vapor. 태양 에너지를 이용하는 담수장치 및 그 작동법에 관한 것이다. 이 장치에 태양 에너지로 가열 매개물을 가열하는 태양열 집적기(12), 증발캔(60)과 상호작동하여 가열 매개물과 증발캔의 원수(62)를 열교환시키고 증발캔에서 수증기(63)를 발생시키는 열교환기(92), 원수탱크(72)와 상호작동하여 증발캔(63)으로부터 수증기(63)를 받아들이고 수증기와 원수탱크의 원수를 열교환시키며 증류수를 얻는 응축기(98), 증류수를 저장하는 증류수 탱크, 증발캔을 진공시키고 내부를 감압하여 증발캔에서 증기발생을 촉진시키는 진공수단 및 증발캔에 원수를 공급하는 수단이 제공된다. 다수의 증발캔(60)이 제공될 때, 증발캔과 상호작동하는 응축기가 제공되어 상류측 증발캔으로부터 수증기(63)를 받아들이고 하류측 증발캔의 원수로 수증기를 냉각하여 증류수를 만들며, 또한 하류측 증발캔에 있는 원수를 가열하여 증기를 발생시킨다.
