Aqueous solutions generally have different saturation temperatures depending on their concentration. Taking advantage of the property that the saturation temperatures are different, a low boiling point aqueous solution 3 is put in the container 1, a high boiling point aqueous solution 4 is put in the container 2, and after connecting these containers with a conduit 5, the non-condensable gas inside the container is When the water is discharged to the outside, the low boiling point aqueous solution 3 starts boiling, and the high boiling point aqueous solution 4

Heat exchangers 6 and 7 are installed in the containers 1 and 2, respectively, and in the container 1 containing the low-boiling point aqueous solution 3, a low-temperature fluid 8 whose temperature is slightly higher than that of the low-boiling point aqueous solution 3 is passed. When the aqueous solution 3 and the low temperature fluid 8 are heat exchanged, the aqueous solution 3 with a low boiling point becomes
It is heated and begins to boil, producing steam 10.
On the other hand, in the container 2 containing the high-boiling point aqueous solution 4, a high-temperature fluid 9 whose temperature is slightly lower than that of the high-boiling point aqueous solution 4 is flowed, and when the high-boiling point aqueous solution 4 and the high-temperature fluid 9 are heat exchanged, the high-boiling point Since the temperature of the aqueous solution 4 falls below the saturation temperature, it absorbs the steam 10 generated in the container 1. In this phenomenon, the heat contained in the cold fluid 8 is transferred to the low-boiling fluid 3 in the heat exchanger 6 in the vessel 1 and is carried by the generated steam 10 through the conduit 5 into the vessel 2. The amount of heat carried into the container 2 is absorbed by the high boiling point fluid 4 and then transferred to the high temperature fluid 9 in the heat exchanger 7. As described above, by utilizing the concentration difference, it becomes possible to use the heat amount of the low temperature fluid 8 as a heat source for the high temperature fluid 9, and this high temperature heat amount can be used as a heat source for motive power or temperature raising.

The temperature state when the temperature is set to s is shown. Under this condition,
The temperature of the low boiling point aqueous solution 3 will be -25℃, while
The temperature of the high boiling point aqueous solution 4 is 50°C. Therefore, a high temperature fluid of about 50°C can be produced from a low temperature fluid of about -25°C. Further, by changing the concentration of the low boiling point aqueous solution 3 and the concentration or pressure of the high boiling point aqueous solution 4, it is possible to create a fluid at any temperature from various low boiling point fluids.

In these flows, when the high boiling point fluid 4 continues to be absorbed by steam, the concentration changes. , the boiling point decreases, the absorption capacity decreases, and the low boiling point aqueous solution 3 decreases. Therefore, if the concentration of the high boiling point aqueous solution 4 is maintained at a constant value, it is necessary to continuously supply the low boiling point aqueous solution 3 in an amount corresponding to the amount of evaporation.
