PURPOSE: A back pressure control system is provided to allow convenient operation of the system by arranging a single unit steam turbine. CONSTITUTION: A system comprises a mesothermal water temperature controller(13) for sensing the temperature of the water from a mesothermal water supply pipe(8); a branch pipe(14) installed between a high voltage/low voltage single unit steam turbine(3) and a heat exchanger(4) for district heating system, and which branches exhaust heat in accordance with the temperature sensed by the mesothermal water temperature controller; an air cooling condenser(11) connected to the branch pipe and which condensates the exhaust heat being introduced; and a plurality of fans(12) for cooling down the air cooling condenser and of which speed and counts are adjusted in accordance with the temperature set by the signal from the mesothermal water temperature controller. Thus, a mesothermal water supply system with an improved stability can be obtained.
