Abstract

본 발명은 가스보일러의 연소 상태를 제어하는 방법에 관한 것으로서, 더욱 구체적으로는 버너에서 가스가 연소하는 경우에 외부로부터 유입되는 공기량이 최적의 상태로 공급되도록 배기팬을 제어하여 가스를 연소시키는 가스보일러의 공연비에 따른 가스압 조정방법에 관한 것이다.The present invention relates to a method of controlling a combustion state of a gas boiler, and more particularly, a gas for combusting gas by controlling an exhaust fan so that the amount of air introduced from the outside is optimally supplied when the gas is combusted in a burner. It relates to a gas pressure adjusting method according to the air-fuel ratio of the boiler.

본 발명의 가스보일러의 공연비에 따른 가스압 조정방법은, 가스보일러가 작동되고 사용자에 의하여 온도가 설정되면, 이것에 따라서 발열량을 결정하고, 상기 발열량에 따른 배기팬의 풍량을 발생시키는 배기팬 회전수를 측정하여, 회전수가 정상 회전수에 도달하지 못하면 전압을 변경하여 배기팬의 회전수를 조정하는 것을 특징으로 한다.In the gas pressure adjusting method according to the air-fuel ratio of the gas boiler of the present invention, when the gas boiler is operated and the temperature is set by the user, the exhaust fan rotation speed for determining the amount of heat generated according to this, and generating the air volume of the exhaust fan according to the amount of heat generated When the rotation speed does not reach the normal speed, it is characterized by changing the voltage to adjust the speed of the exhaust fan.
