In the present system, Freon is recirculated in a closed loop which includes a first heat exchanger having a tank for holding Freon in a liquid state at elevated temperature and pressure, and second, third, and fourth heat exchangers which receive Freon at different times from the first heat exchanger by gravity flow and successively cool, heat and discharge the heated Freon in a liquid state through a fluid motor whose discharge is connected back to the tank in the first heat exchanger. Water from the cooling tower of a steam power plant is used to cool the Freon in the first heat exchanger and at different times in the other heat exchangers. Hot water from the waste steam outlet of steam turbines in the steam power plant is used to heat the Freon at other times in the second, third and fourth heat exchangers.
