間に塔を流下する他の熱媒体と熱交換させる。The hot water pushed up by pressurization by the pump 2 rises in a heat exchanger 3 provided along the tower, during which it exchanges heat with other heat medium flowing down the tower.
従って、上記温水は次第にその温度が低下しながら塔上
に達し、そこから自然流下により塔１の下まで落下せし
められ、水車４に導入される。Therefore, the hot water reaches the top of the tower while its temperature gradually decreases, and is allowed to fall to the bottom of the tower 1 by gravity from there, and is introduced into the water wheel 4.
この水車４によって得られる動力は前記ポンプ２の駆動
に用いるが、ポンプ及び水車の効率等に基づくエネルギ
の損失分は他から補給する必要がある。The power obtained by the water wheel 4 is used to drive the pump 2, but the energy lost due to the efficiency of the pump and water wheel must be replenished from elsewhere.

will be introduced in
このタービン６を駆動した熱媒体は、塔１に沿って空冷
管７を上部の空冷凝縮器５まで環流するが、その間にお
いても空冷により若干凝縮する。The heat medium that drove the turbine 6 circulates through the air-cooled pipe 7 along the tower 1 to the air-cooled condenser 5 at the upper part, but even during that time, it is slightly condensed due to air cooling.
なお、図中８は空冷凝縮器５及び空冷管７の冷却を行う
ファン、９はタービン６によって駆動される発電機を示
している。In the figure, 8 indicates a fan that cools the air-cooled condenser 5 and the air-cooled pipes 7, and 9 indicates a generator driven by the turbine 6.

めに建設費を節減することができる。In the above, it has been explained that the tower 1 is used and the heat exchanger 3 and the air-cooled condenser 5 are installed on it. In addition to installing a heat exchanger 3, etc., an air-cooled condenser 5 can also be installed at the top of the slope. In this case, various equipment can be installed on the slope of a mountain or hill without constructing a huge tower. construction costs can be reduced.
