PURPOSE: An apparatus and a method for controlling the circulation of heating water are provided to improve the heating efficiency of a heating system or a boiler system by selectively controlling the flowing direction of heating water depending on the temperature and flow rate of the heating water. CONSTITUTION: An apparatus for controlling the circulation of heating water comprises a first measurement unit(100/1), a second measurement unit(100/2), first, second, third, and fourth solenoid valves(102/1,102/2,102/3,102/4), and a control unit(104). The first measurement unit measures the temperature and flow rate of heating water flowing into a circulation pipe. The second measurement unit measures the temperature and flow rate of heating water flowing out of the circulation pipe. The first solenoid valve is installed between the first measurement unit and the inlet of the circulation pipe. The second solenoid valve is installed between the first measurement unit and the outlet of the circulation pipe. The third solenoid valve is installed between the second measurement unit and the inlet of the circulation pipe. The fourth solenoid valve is installed between the second measurement unit and the outlet of the circulation pipe. The control unit selectively controls one or more the solenoid valves to bidirectionally circulate the heating water through the circulation pipe. |
