Abstract

본 발명은 가스보일러의 열교환기에서 발생되는 저온부식을 방지하기 위한 방법에 관한 것으로서, 더욱 구체적으로는 응축수가 발생되는 소정온도 이상으로 난방공급수의 온도를 제어함으로써 열교환기의 난방배관인접부에서 발생되는 저온부식을 방지할 수 있는 가스보일러 제어방법에 관한 것이다.The present invention relates to a method for preventing low-temperature corrosion in a heat exchanger of a gas boiler, and more particularly, to a method for preventing corrosion at a low temperature in a heat exchanger of a gas boiler, To a gas boiler control method capable of preventing low-temperature corrosion which is generated.

본 발명의 저온부식예방을 위한 가스보일러 제어방법은, 난방배관이 내부를 통과하는 듀얼타입 열교환기를 포함하는 가스보일러에 있어서, 난방공급관을 통과하는 난방수의 난방공급온도를 측정하는 제1단계; 측정된 난방공급온도가 소정온도(T) 이상이면 정상동작하고, 소정온도(T) 이하이면 온수모드로 전환하여 가열하는 제2단계; 및 온수모드상태에서 난방공급온도를 재측정하여 소정온도(T) 이상이면 난방모드로 전환하고 소정온도(T) 이하이면 온수모드를 유지하여 계속 가열하는 제3단계로 구성된다.A gas boiler control method for preventing low-temperature corrosion according to the present invention is a gas boiler including a dual-type heat exchanger in which a heating pipe passes through, a first step of measuring a heating supply temperature of heating water passing through a heating pipe; A second step of performing normal operation when the measured heating supply temperature is equal to or higher than the predetermined temperature T and switching to a hot water mode when the measured heating supply temperature is equal to or lower than the predetermined temperature T; And a third step of re-heating the heating supply temperature in the hot water mode and switching to the heating mode if the temperature is higher than the predetermined temperature T and continuing heating while maintaining the hot water mode if the temperature is lower than the predetermined temperature T.
