A considerable amount of energy is taken up by driving the pump and auxiliary equipment such as the liquid supply pump (■), and the output of the turbine generator (■) decreases by that amount, which has the disadvantage that the cycle power generation efficiency is not very good. .

融雪水の水頭・落差により回すシステムである。An embodiment of the present invention will be described with reference to the drawings. In a power generation device using a low-boiling point medium terpino 1 and a water turbine 2, the working medium is a low-boiling point substance such as chlorofluorocarbon that can become a high-pressure gas even at low temperatures. 1 near 1
An evaporator 4 that heats geothermal hot water at 00'C or less, and a condenser 6 for low boiling point medium vapor are installed in a snow dam 5 that has a water head and head and is constructed higher than the power generation device. This is a system in which the turbine 1 is rotated by high-pressure steam, which is a low boiling point medium, and the water turbine 1 is rotated by the water head and head of snowmelt water from the snow water dam 5.

うこともできる。In this embodiment, the water turbine 2 is connected in series to the low boiling point medium turbine 1 and the generator 3 via the clutch C, so in the winter, the water turbine 2 is disconnected and low temperature difference power generation is performed using only the turbine 1. It is also possible to perform combined power generation using the Turpinto turbine 2 by engaging the clutch C when the snow melts in the spring.

による水力発電が行える。The present invention configured as described above has the following advantages: (1) Since the condenser 6 for fluorocarbons etc. is provided in the snow water of the snow water dam 5, a cooling water pump for the condenser is not required; Since the condensate from No. 6 naturally flows down to the evaporator 4 with the water head and head, the supply pump is omitted. Furthermore, due to the latent heat of condensation of vapor such as fluorocarbons in the condenser No. As the snow melts, small-scale hydropower generation is possible despite the brown water season in winter, and combined with the 6 large hydropower generation during the summer high water season, two water turbines can be generated throughout the year.
