抄録: The field experiment on the sea-thermal power generation was carried out in September of 1982 at the station off Shimane, western Japan Sea. The experiment was conducted by the team of Nagasaki University supported by some students and officials concerned. The plant ship Marushige-maru, 110 gross ton, was floated over freely at the position of NW 38km from the Cape Hino. The sea depth was about 220m. The water temperature was about 20~23℃ at the surface and was about 2℃ at the depth of 190m. For the pumping the bottom cold water, a flexible vinyl chloride pipe line with a submergible pump was hung from the ship. The details for the floating the ship and the pumping the bottom water were omitted in this report, because they were another paper. The specials in this research are as follows. a) As a working substance a flon 12 was used, because of the safety for the students. b) Heat-exchangers were made from many tubes, groupes of tubes different from a shell and tubes, these tubes types reduced the weight of the apparatus. c) As a flon turbine, a screw type machine by expansion of gases was used, the reason for use of machine was the matching of rotations between the flon turbine and the generator. On the sea, maximum output from the generator was 1512 watt, to make this power, 1305 watt of net hydraulic loses for circulating the water and 560 watt of loses for the flon, 1305+560=1865 watt of total loses were measured. It was noted here, net hydraulic loses are pure loses in the piping and the heat-exchanger. No loses in the pumps and driving motor were contained. Maximum revolution of the machine was 1500 rpm. Maximum heat output from the heat-exchanger was 1.6 kcal/kg.
