摘要
The present invention relates to a kind of methods of preventing freezing for a gas boiler, more specifically, to a kind of method of preventing freezing for a heating tube by executing the prevention circulatory function freezed when the prevention combustion function freezed is that impossible main valve due to for oiling is closed and when a kind of method that the controlling to freeze for a gas boiler is prevented. Determine whether that the first order that the temperature of the heating water detected when burning by the temperature detection sensor 80 of boiler stops is 2C or lower; Controller 100 drives gas valve 40, hair dryer 20, circulating pump 60 and ignition transformer 30, a second step, judges whether that the igniting of burner 11 is by igniter 30; Determine whether to be performed in second step if lighted a fire, the temperature of heating water rises to the third step of a predetermined temperature, and antifreeze combustion function is terminated when the temperature of heating water is increased to a predetermined temperature; One the 4th step determines whether that the temperature of water supply water is lower than 4C lower than 2C or the first step; If the temperature of heating water is less than or equal to the 4C in the 4th step, controller 100 drives circulating pump 60 to execute a frost prevention circulatory function, determine whether when the temperature for supplying water has improved a predetermined temperature, the temperature of heating water is increased to a predetermined temperature, and terminates the 5th step one by one for the prevention circulatory function freezed. Thus, prevent the effect of heating tube freezed to be prevented from the closing without igniting due to closing or the gas supply of main valve.
