Title: Method for indicating operating state of circulating pump of gas boiler
Inventor: JEONG WAN SU
IPC: F24H9/20
Filed: 1998-12-29
Abstract: PURPOSE: A method is provided to inform a user of trouble of a circulating pump by indicating the state of the circulating pump of a gas boiler. CONSTITUTION: A system measures a first temperature(T1) of heating water from a heat exchanger and stores a data. The system decides if gas combustion is normal in a burner. If so, the system sends a signal for deciding if the set time passes. If not, the system sends a signal for measuring and storing temperature again. The system decides if the set time passes with the signal. If so, the system sends a signal for measuring and storing a second temperature(T2) and if not, a timer delays a signal flow. Also, the system compares an absolute value of the difference between the first and the second temperature with the set temperature. If the absolute value of the difference is more than the set temperature, the system decides a circulating pump is normal. If the absolute value is less than the set temperature, the system decides that the circulating pump is out of order.
