It relates to a method of preventing overheating of a gas boiler to prevent energy consumption.
일반적으로, 가스보일러는 액화석유가스(LPG)나 액화천연가스(LNG) 또는 도시가스를 내부에서 연소시키고, 이 연소과정에서 발생되는 연소열을 이용하여 물을 가열한 후, 가열된 물을 순환펌프를 통해 실내의 난방배관으로 순환시켜 실내를 난방하거나 목용탕 또는 주방으로 공급하는 장치이다.In general, a gas boiler burns liquefied petroleum gas (LPG), liquefied natural gas (LNG), or city gas inside, heats water using combustion heat generated during the combustion process, and then heats the circulated pump. It is a device that circulates through the heating pipe in the room and heats the room or supplies it to the bath or kitchen.
도 3은 상기와 같이 동작하는 가스보일러의 내부구성을 나타낸 정면도로, 본체(200)의 내측에는 가스의 연소열을 이용하여 난방수를 가열하는 연소실(210)이 형성되어 있는데, 이 연소실(210)의 저부에는 유입되는 가스를 연소시키는 버너(211)가 장착되어 있고, 버너(211)의 상부에는 가스의 연소시 발생되는 연소열을 이용하여 난방수를 가열하는 주열교환기(212)가 장착되어 있다.3 is a front view showing the internal structure of the gas boiler operating as described above, the combustion chamber 210 for heating the heating water using the combustion heat of the gas is formed inside the main body 200, the combustion chamber 210 At the bottom of the burner is mounted a burner 211 for burning the incoming gas, and the top of the burner 211 is equipped with a main heat exchanger 212 for heating the heating water using the heat of combustion generated during combustion of the gas.
한편, 본체(200)의 상부에는 가스의 연소에 필요한 공기를 흡입하는 급기구(201)와 연소실(210)의 배기가스를 외부로 배출하는 배기구(202)가 각각 형성되어 있으며, 급기구(201)를 통해 흡입된 공기는 송풍팬(250)에 의해 연소실(210)내로 공급된다.On the other hand, the upper portion of the main body 200 is provided with an air supply port 201 for sucking the air necessary for the combustion of gas and an exhaust port 202 for discharging the exhaust gas of the combustion chamber 210 to the outside, respectively, Air sucked through) is supplied into the combustion chamber 210 by the blowing fan 250.
또한, 버너(211)로 공급되는 가스를 점화시키기 위해 필요한 고전압을 발생하는 점화트랜스(220)가 본체(200)의 내측 배면에 고정되어 있는데, 이 점화트랜스(220)에서 발생된 고전압은 연소실(210)의 일측면에 고정되어 있는 점화플러그(221)로 공급된다.In addition, an ignition transformer 220 that generates a high voltage necessary to ignite the gas supplied to the burner 211 is fixed to the inner rear surface of the main body 200, and the high voltage generated in the ignition transformer 220 is a combustion chamber ( It is supplied to the spark plug 221 fixed to one side of the 210.
한편, 외부의 가스를 버너(211)로 공급하는 가스공급관(207)의 소정부위에는 가스의 공급상태를 제어하는 가스밸브(240)가 장착되어 있으며, 상기 주열교환기(212)에서 가열된 난방수는 보조열교환기(270)로 공급된다. 이 보조열교환기(270)는 직수공급관(205)을 통해 유입되는 직수를 열교환시켜 온수로 변환시킨다.On the other hand, a predetermined position of the gas supply pipe 207 for supplying the external gas to the burner 211 is equipped with a gas valve 240 for controlling the gas supply state, the heating water heated in the main heat exchanger 212 Is supplied to the auxiliary heat exchanger 270. The auxiliary heat exchanger 270 exchanges the direct water introduced through the direct water supply pipe 205 and converts it into hot water.
또한, 보조열교환기(270)로 공급된 난방수와 직수는 순환펌프(260)의 구동에 따라 난방수 공급관(203)을 통해 실내의 난방배관으로 공급되거나 열교환되어 온수 공급관(204)을 통해 목용탕이나 주방으로 공급되고, 실내의 난방배관을 통과한 난방수는 난방수 환수관(206)을 통해 물탱크(240)로 환수되는데, 이러한 모든 동작은 제어회로부(230)에 의해 제어된다.In addition, the heating water and the direct water supplied to the subsidiary heat exchanger 270 are supplied to the heating pipe of the room through the heating water supply pipe 203 or heat exchanged according to the operation of the circulation pump 260, and the heat is supplied through the hot water supply pipe 204. The heating water supplied to the molten metal or the kitchen and passed through the heating pipe of the room is returned to the water tank 240 through the heating water return pipe 206, and all these operations are controlled by the control circuit unit 230.
상기와 같이 구성된 종래의 가스보일러를 구동시키면 송풍팬(250)이 고속으로 회전하여 연소실(210) 내부를 환기시킨 후, 저속으로 회전하는데, 이때 가스밸브(240)가 개방되어 버너(211)로 가스를 공급하고, 공급된 가스는 점화플러그(221)의 고압방전에 의해 착화된다. 따라서, 가스의 연소열에 의해 가열되거나 열교환된 난방수 또는 온수가 실내의 난방배관이나 목욕탕 또는 주방으로 공급된다.When the conventional gas boiler configured as described above is driven, the blower fan 250 rotates at a high speed to ventilate the combustion chamber 210 and then rotates at a low speed. At this time, the gas valve 240 is opened to the burner 211. The gas is supplied, and the supplied gas is ignited by the high pressure discharge of the spark plug 221. Therefore, the heating water or hot water heated or heat-exchanged by the combustion heat of the gas is supplied to the heating pipe or the bathroom or kitchen of the room.
한편, 보일러의 과열을 방지하기 위하여 주열교환기(212)에서 배출되는 난방수의 온도를 검출하는 온도검출센서(290)가 주열교환기(212)의 배출구측에 장착되어 있는데, 이 온도검출센서(290)에서 검출된 난방수의 온도가 소정의 온도, 통상적으로 88℃를 초과하면 보일러는 강제적으로 소화된다. 즉, 버너(211)로 공급되는 가스는 차단되고, 송풍팬(2590)과 순환펌프(260)의 구동은 중지된다.On the other hand, in order to prevent overheating of the boiler, a temperature detection sensor 290 for detecting the temperature of the heating water discharged from the main heat exchanger 212 is mounted on the outlet side of the main heat exchanger 212, the temperature detection sensor 290 The boiler is forcibly extinguished if the temperature of the heating water detected at C) exceeds a predetermined temperature, typically 88 ° C. That is, the gas supplied to the burner 211 is cut off, and the driving of the blower fan 2590 and the circulation pump 260 is stopped.
그러나, 이와같이 송풍팬(250)과 순환펌프(260)의 구동을 중지시키면 난방수의 온도가 충분히 하강하지 못하고 과열된 상태로 장시간 유지된다. 따라서, 난방수에서 방출된 열기로 인해 전장품의 열화가 가속되어 보일러 고장의 원인으로 작용하게 된다.However, when the driving of the blower fan 250 and the circulation pump 260 is stopped in this way, the temperature of the heating water is not sufficiently lowered and is maintained for a long time in an overheated state. Therefore, deterioration of the electrical equipment is accelerated due to the heat released from the heating water, which causes the boiler to malfunction.
이와같은 문제점을 해소하기 위하여 종래에는 도 4에 도시된 것처럼 과열로 인해 버너(211)가 강제적으로 소화되면 주열교환기(212)에서 배출되는 난방수의 온도가 85℃를 초과하는지 검출하고(301 내지 304), 검출된 난방수의 온도가 85℃ 미만이면 송풍팬(250)과 순환펌프(260)의 구동을 중지시키지만(307), 난방수의 온도가 85℃를 초과하면 난방수의 온도가 80℃ 이하로 하강할 때까지 송풍팬(250)과 순환펌프(260)의 구동상태를 유지하여 보일러의 과열상태를 해소하였다(305 내지 306).In order to solve such a problem, conventionally, when the burner 211 is forcibly extinguished due to overheating as shown in FIG. 4, it is detected whether the temperature of the heating water discharged from the main heat exchanger 212 exceeds 85 ° C. 304), if the detected temperature of the heating water is less than 85 ℃ stop the driving of the blower fan 250 and the circulation pump 260 (307), if the temperature of the heating water exceeds 85 ℃ temperature of the heating water is 80 The overheated state of the boiler was removed by maintaining the driving state of the blower fan 250 and the circulation pump 260 until the temperature was lowered to below 占 폚 (305 to 306).
그러나, 온도검출센서의 오동작으로 인해 열교환기에서 배출되는 난방수의 온도를 정확하게 검출하지 못하면, 난방수의 온도가 충분히 하강하였는데도 불구하고 송풍팬과 순환펌프가 지속적으로 구동되므로, 불필요한 에너지 소비가 발생할 뿐만 아니라 난방수의 온도를 과도하게 하강시킬 수 있다는 문제점이 있었다.However, if the temperature of the heating water discharged from the heat exchanger cannot be accurately detected due to the malfunction of the temperature detection sensor, the blower fan and the circulating pump are driven continuously even though the temperature of the heating water is sufficiently lowered. Not only that, there was a problem that can excessively lower the temperature of the heating water.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 과열로 인해 가스보일러가 강제소화된 이후에 소정의 시간이 경과하도록 난방수의 온도가 하강하지 않으면 송풍팬과 순환펌프의 구동을 중지시켜 온도검출샌서의 오동작으로 인한 불필요한 에너지 소비를 방지하는 가스보일러의 과열방지방법을 제공하는 것을 그 목적으로 한다.Therefore, the present invention has been invented to solve the above problems, and stops the operation of the blower fan and the circulation pump if the temperature of the heating water does not decrease so that a predetermined time elapses after the gas boiler is forcibly extinguished due to overheating. It is an object of the present invention to provide a method of preventing overheating of a gas boiler that prevents unnecessary energy consumption due to malfunction of a temperature detection sandwich.
상기와 같은 목적을 달성하기 위하여 본 발명은, 가스보일러의 제어방법에 있어서, 과열로 인해 버너가 강제적으로 소화되면 주열교환기에서 배출되는 난방수의 온도가 85℃를 초과하는지 검출하는 제 1 단계와, 상기 제 1 단계에서 난방수의 온도가 85℃를 초과하면 소정의 시간동안 순환펌프와 송풍팬의 구동상태를 유지하며 난방수의 온도에 변화가 있는지 검출하는 제 2 단계와, 상기 제 2 단계에서 소정의 시간이 경과하도록 난방수의 온도에 변화가 발생하지 않으면 순환펌프와 송풍팬의 구동을 중지시키는 제 3 단계를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a gas boiler control method comprising: a first step of detecting whether a temperature of heating water discharged from a main heat exchanger exceeds 85 ° C. when a burner is forcibly extinguished due to overheating; If the temperature of the heating water exceeds 85 ℃ in the first step, the second step of maintaining the driving state of the circulation pump and the blowing fan for a predetermined time and detecting whether there is a change in the temperature of the heating water, and the second step If the change in the temperature of the heating water does not occur so that a predetermined time in the elapsed time characterized in that it comprises a third step of stopping the driving of the circulation pump and the blowing fan.
