The present invention relates to a method for controlling power saving of a gas boiler that minimizes power consumption of a boiler by stopping a pump.
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 공급되는 가스량을 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 portion 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 amount of gas supplied, 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.
이와같이 구성된 종래의 가스보일러는 비례제어방식에 의해 구동된다. 즉, 사용자가 난방수의 온도를 설정하면 주열교환기(212)의 배출구측에 장착된 온도검출센서(290)에서 검출되는 난방수의 온도에 따라 가스밸브(240)의 개방정도와 송풍팬(250)의 회전속도가 가변되어 난방수의 온도를 일정하게 유지한다.The conventional gas boiler configured as described above is driven by a proportional control method. That is, when the user sets the temperature of the heating water, the opening degree of the gas valve 240 and the blowing fan 250 are determined according to the temperature of the heating water detected by the temperature detection sensor 290 mounted on the outlet side of the main heat exchanger 212. ), The rotation speed is variable to keep the temperature of the heating water constant.
그러나, 상기와 같이 난방수의 온도에 따라 가스밸브(240)의 개방정도와 송풍팬(250)의 회전속도를 가변시켜 최소의 열량으로 난방수를 가열하여도 난방수의 온도가 지속적으로 상승하는 경우가 있다. 종래에는 이와같이 난방공급수의 온도가 상승하여 사용자가 설정한 온도보다 기설정된 크기만큼 높은 난방소화온도에 도달하면 도 4에 도시된 것처럼 버너(211)를 소화시켜 난방수의 과열을 방지하였다.However, the temperature of the heating water is continuously increased even when the heating water is heated with a minimum amount of heat by varying the opening degree of the gas valve 240 and the rotation speed of the blowing fan 250 according to the temperature of the heating water as described above. There is a case. Conventionally, when the temperature of the heating supply water rises to reach the heating fire extinguishing temperature higher than the temperature set by the user, the burner 211 is extinguished as shown in FIG. 4 to prevent overheating of the heating water.
즉, 운전중인 보일러의 온도검출센서(290)를 통해 검출된 난방공급수의 온도가 난방소화온도 보다 높으면(301 내지 302), 가스밸브(240)를 폐쇄하고 송풍팬(250)의 구동을 중지시켜 버너(211)를 소화시키는데(303 내지 304), 이때 외부에 설치되는 온도검출센서(290)의 검출온도와 난방배관을 따라 유동되는 난방수의 온도가 상이할 수 있음에 따라 순화펌프(260)의 구동상태는 유지된다(305).That is, when the temperature of the heating supply water detected by the temperature detection sensor 290 of the boiler in operation is higher than the heating fire extinguishing temperature (301 to 302), the gas valve 240 is closed and the driving of the blower fan 250 is stopped. By extinguishing the burner 211 (303 to 304), the purifying pump 260 according to the detection temperature of the temperature detection sensor 290 installed outside and the temperature of the heating water flowing along the heating pipe may be different. ) Is maintained (305).
한편, 난방공급수의 온도가 강하되어 사용자가 설정한 온도보다 기설정된 크기만큼 낮은 난방점화온도에 도달하면(306), 가스밸브(240)와 송풍팬(250)을 구동하여 연소실(210)내로 가스와 연소용 공기를 공급한 후, 점화플러그(221)를 통해 고압방전을 일으켜 버너(211)를 재점화한다.On the other hand, when the temperature of the heating supply water drops and reaches the heating ignition temperature lower by the predetermined size than the temperature set by the user (306), the gas valve 240 and the blowing fan 250 is driven into the combustion chamber 210. After supplying gas and combustion air, a high-pressure discharge is generated through the spark plug 221 to re-ignite the burner 211.
그러나, 실내의 난방배관으로 공급되는 난방수의 온도를 일쩡하게 유지하기 위하여 버너를 소화시키는 경우에도 상기된 것처럼 순환펌프의 구동상태는 유지됨에 따라 지속적인 전력소비가 발생한다는 문제점이 있었다.However, even when the burner is extinguished in order to maintain the temperature of the heating water supplied to the indoor heating pipe, there is a problem in that the power consumption is continuously generated as the driving state of the circulation pump is maintained as described above.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 실내의 난방배관으로 공급되는 난방수의 온도가 난방소화온도에 도달하면 난방점화온도에 도달할 때까지 순환펌프의 구동을 중지시켜 보일러의 소비전력을 최소화시키는 가스보일러의 절전제어방법을 제공하는 것을 그 목적으로 한다.Therefore, the present invention is invented to solve the above problems, when the temperature of the heating water supplied to the heating pipe in the room reaches the heating fire extinguishing temperature, the circulation pump is stopped until the heating ignition temperature reaches the boiler It is an object of the present invention to provide a gas boiler control method for minimizing power consumption of a gas boiler.
상기와 같은 목적을 달성하기 위하여 본 발명은, 비례제어를 통해 난방수의 온도를 일정하게 유지하는 가스보일러의 제어방법에 있어서, 실내의 난방배관으로 공급되는 난방수의 온도가 사용자가 설정한 온도보다 기설정된 크기만큼 높은 난방소화온도에 도달하면 가스밸브를 폐쇄하고 송풍팬의 구동을 중지시켜 버너를 소화시킨 후, 소정의 시간이 경과하면 순환펌프의 구동도 중지시키는 제 1 단계와, 상기 제 1 단계에서 순환펌프의 구동을 중지시킨 후, 공급되는 난방수의 온도가 사용자가 설정한 온도보다 기설정된 크기만큼 낮은 난방점화온도에 도달하면 소정의 시간동안 순환펌프를 구동하여 난방수를 순환시키는 제 2 단계와, 상기 제 2 단계에서 난방수의 순환에도 불구하고 공급되는 난방수의 온도가 난방점화온도 보다 낮으면 가스밸브와 송풍팬 및 점화트랜스를 구동하여 버너를 재점화시키는 제 3 단계를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the gas boiler control method for maintaining a constant temperature of the heating water through a proportional control, the temperature of the heating water supplied to the heating pipe of the room is set by the user A first step of closing the gas valve and stopping the driving of the blower fan to extinguish the burner when the heating fire temperature reaches a higher preset size, and stopping the driving of the circulation pump after a predetermined time elapses; After stopping the operation of the circulating pump in the first step, when the temperature of the supplied heating water reaches a heating ignition temperature lower by a predetermined size than the temperature set by the user, the circulation pump is circulated for a predetermined time.

도 1은 본 발명이 적용되는 가스보일러의 제어장치를 나타낸 블록도로, 실내의 난방배관으로 공급되는 난방수의 온도를 검출하는 온도검출센서(10)가 제어부(40)에 접속되어 있으며, 또한 제어부(40)에는 버너의 점화 및 소화상태를 검출하는 염전압 검출부(20)가 접속되어 있다.1 is a block diagram showing a control device of a gas boiler to which the present invention is applied, in which a temperature detection sensor 10 for detecting a temperature of heating water supplied to a heating pipe in a room is connected to a control unit 40, and also a control unit. A salt voltage detection unit 20 is connected to the 40 for detecting the ignition and extinguishing state of the burner.
한편, 제어부(40)는 온도검출센서(10)룰 통해 검출된 난방수의 온도에 따라 점화트랜스(30), 가스밸브(50), 송풍팬(60) 및 순화펌프(70)의 구동을 제어하여 버너를 점화 또는 소화시켜 난방수의 과열 및 과냉을 방지한다.On the other hand, the control unit 40 controls the driving of the ignition transformer 30, the gas valve 50, the blowing fan 60 and the purifying pump 70 according to the temperature of the heating water detected through the temperature detection sensor 10 rule. To ignite or extinguish the burner to prevent overheating and overcooling of the heating water.
다음에는 상기와 같이 구성된 제어장치에 적용되는 본 발명에 따른 가스보일러의 절전제어방법을 도 2를 참조하여 상세히 설명한다.Next, a power saving control method of the gas boiler according to the present invention applied to the control device configured as described above will be described in detail with reference to FIG. 2.
도 2는 본 발명에 따른 가스보일러의 절전제어방법을 나타낸 흐름도로, 운전중인 보일러의 온도검출센서(10)를 통해 검출된 난방수의 온도가 사용자가 설정한 온도보다 기설정된 크기만큼 높은 난방소화온도에 도달하면(101 내지 102), 제어부(40)는 난방수의 과열을 방지하기 위하여 가스밸브(50)를 폐쇄하고 송풍팬(60)의 구동을 중지시켜 버너를 소화시킨다(103 내지 104).2 is a flowchart illustrating a power saving control method of a gas boiler according to the present invention, wherein the temperature of the heating water detected through the temperature detection sensor 10 of the boiler in operation is higher than the temperature set by the user. When the temperature is reached (101 to 102), the control unit 40 closes the gas valve 50 and stops the driving of the blower fan 60 to prevent overheating of the heating water to extinguish the burner (103 to 104). .
이때, 외부에 설치된 온도검출센서(10)의 검출온도와 실내의 난방배관을 따라 유동되는 난방수의 온도가 상이할 수 있음에 따라 순화펌프(70)의 구동상태는 유지된다(105). 이와같이, 버너를 소화시킨 상태에서 소정의 시간이 경과하면 제어부(40)는 순환펌프(70)의 구동도 중지시켜 가스보일러의 전력소비를 최소화시킨다(106 내지 107).At this time, the driving temperature of the purified pump 70 is maintained as the detected temperature of the temperature detection sensor 10 installed outside and the temperature of the heating water flowing along the heating pipe of the room may be different (105). As such, when a predetermined time passes while the burner is extinguished, the controller 40 also stops the driving of the circulation pump 70 to minimize the power consumption of the gas boiler (106 to 107).
한편, 버너가 소화된 이후에 온도검출센서(10)를 통해 검출된 난방수의 온도가 사용자가 설정한 온도보다 기설정된 크기만큼 낮은 난방점화온도에 도달하면(108), 제어부(40)는 외부에 설치된 온도검출센서(10)의 검출온도와 실내의 난방배관을 따라 유동되는 난방수의 온도차를 해소하기 위해 순화펌프(70)를 소정시간 구동하여 난방수를 순환시킨다(109 내지 110).On the other hand, if the temperature of the heating water detected by the temperature detection sensor 10 after the burner is extinguished reaches a heating ignition temperature lower by a predetermined size than the temperature set by the user (108), the controller 40 is external In order to eliminate the temperature difference between the detected temperature of the temperature detection sensor 10 and the heating water flowing along the heating pipe in the room, the purified pump 70 is driven for a predetermined time to circulate the heating water (109 to 110).
상기와 같이 난방수를 순환시켰음에도 불구하고 공급되는 난방수의 온도가 난방점화온도 보다 낮으면(111), 제어부(40)는 난방수의 과냉을 방지하기 위하여 가스밸브(50)와 송풍팬(60) 및 점화트랜스(30)를 구동하여 버너를 재점화시킨다. 따라서, 냉각된 난방수는 다시 가열된다(112).Even though the heating water is circulated as described above, if the temperature of the supplied heating water is lower than the heating ignition temperature (111), the controller 40 controls the gas valve 50 and the blowing fan to prevent the cooling of the heating water. 60) and the ignition transformer 30 to re-ignite the burner. Thus, the cooled heating water is heated again (112).
