PURPOSE:To enable to provide a high operational efficiency and economical property on the whole, by a method wherein a device is combined with an arbitrary type second refrigerator so that temperature of cold water produced by a solar refrigerator is not so low and a sufficient effect thereof can be produced. CONSTITUTION:A heat accumulating tank 25 for cold water has partitions 32, 33, 34, 35, 36 and 37, the right of a drawing is a low temperature side, the left is a high temperature side, and a middle temperature area is located between the middle partitions 34 and 35. Cold water produced by a solar refrigerator 20 enters a central middle temperature area through a line 23, and returns back to the solar refrigerator 20 from the left high temperature side by means of a pump 24 and a line 23'. This invention employs a second refrigerator 40 which may be an absorption type refrigerator or a compression type refrigerator with the selection at the high degree of freedom. Cold water pumped up from the middle temperature range flows to the second refrigerator 40 through a line 44 and a pump 45, and is further cooled. Cold water, cooled to about 7 deg.C by the second refrigerator, enters the low temperature range on the right of the heat accumulator 25 through a line 43. Cold water fed therefrom to a load 30 by a pump 31 is heated to about 14 deg.C, and flows to the high temperature side on the left of the heat accumulator 25. |
