OPERATION CONTROLLING APPARATUS FOR PARALLEL BOILERS AND ITS CONTROLLING METHOD THEREOF

摘要

PURPOSE: A device and a method for controlling the hot-water operation of parallely-connected boilers are provided to ensure smooth hot-water supply and extended life span of the boilers by operating the boilers according to priority considering the accumulated operating hours. CONSTITUTION: A device for controlling the hot-water operation of parallely-connected boilers comprises a total operating hour calculation unit(16), a heating hour calculation unit(17), central processing units(11,21), and a controller(2). The total operating hour calculation unit accumulates and calculates the total operating hours according to the heating and hot-water operations of boilers. The heating hour calculation unit calculates the duration of heating operation of the boilers. The central processing units receive output signals from the total operating hour calculation unit and the heating hour calculation unit in real time and stores the output signals in an EEPROM(15). The controller uses the output signal data for determining priority of the boilers for hot-water supply.
