Description

보일러의 난방배관 및 온수배관의 동파방지방법 {Method for preventing freezing of heating pipe and hot-water pipe of boiler}FIELD OF THE INVENTION [0001] The present invention relates to a method for preventing freezing of a heating pipe and a hot-water pipe of a boiler,

본 발명은 보일러의 난방배관 및 온수배관의 동파방지방법에 관한 것으로, 구체적으로는 보일러 내부의 난방공급수 온도센서를 이용하여 난방배관의 동파를 방지함과 아울러 삼방밸브의 제어를 통한 온수배관의 동파까지도 방지할 수 있는 보일러의 난방배관 및 온수배관의 동파방지방법에 관한 것이다.The present invention relates to a method for preventing freezing of a heating pipe and a hot water pipe of a boiler, and more particularly, to a method of preventing freezing of a heating pipe by using a heating water temperature sensor inside a boiler, The present invention also relates to a method of preventing freezing of a heating pipe and a hot water pipe of a boiler which can prevent even a frost wave.

일반적인 가스보일러는 도 1을 참조하면, 난방시 순환펌프(140)에 의해 내부관수를 강제순환시켜 난방열교환기(110)에서 버너(160)의 연소열을 흡수하여 온도를 상승시키고 삼방밸브(120)의 작동에 따라 난방배관(200)으로 공급하여 실내난방에 이용할 수 있도록 하는 한편, 온수 사용시에는 보일러 내부의 내부관수를 순환시켜 난방열교환기(110)에서 흡수된 열을 급탕열교환기(130)로 공급하여 직수입구로 유입된 직수가 급탕열교환기(130)가 가지고 있던 열을 흡수하도록 하여 온수출구로 따뜻한 온수를 공급하도록 하는 작용을 한다.1, in a typical gas boiler, the internal water is forcedly circulated by a circulation pump 140 during heating to absorb the heat of combustion of the burner 160 in the heat exchanger 110 to raise the temperature, The heating water is supplied to the heating pipe 200 according to the operation so that it can be used for heating the room. On the other hand, when hot water is used, the internal water in the boiler is circulated and the heat absorbed in the heating heat exchanger 110 is supplied to the hot water heat exchanger The direct water flowing into the direct inlet port functions to absorb the heat of the hot water heat exchanger 130 and to supply the hot water to the hot water outlet.

이와 같은 보일러에서 콘트롤러(100)는 외출시 난방수 온도센서(150)를 통해 내부관수의 온도를 감지한 결과 내부관수가 동파방지 설정온도, 즉 관수의 온도가 특정온도 이하로 내려갈 때 보일러의 동파방지를 위해 보일러가 자동으로 가동되도록 설정한 온도, 이하로 내려가는 것으로 감지되면 보일러를 가동하여 내부관수의 온도를 상승시키고 난방배관(200)을 순환하도록 하며 이어 설정된 일정 온도 이상이 되면 보일러를 정지시키는 동파방지기능을 구비하고 있다.In the boiler, the controller 100 senses the temperature of the internal water through the heating water temperature sensor 150 at the time of going out. As a result, when the internal water temperature is lowered to the predetermined value, that is, The boiler is operated to raise the temperature of the internal water and circulate the heating pipe 200. When the temperature of the boiler is more than a predetermined temperature, the boiler is stopped It has a frost protection function.

이러한 종래 동파방지기능은 기존 건물들의 낮은 단열효과를 감안하여 난방배관의 동파방지만을 추구하고 있으나 최근의 건물들은 외부와의 단열효과가 향상되어 난방동파의 위험성은 줄어들고 있는 실정이다. 이에 반해, 온수배관의 동파는 겨울철 추운 날씨에 보온재를 적용하여도 빈번하게 발생되고 있어 온수사용에 불편이 늘고 있으므로 온수배관의 동파를 방지해야 할 필요성이 대두되고 있다.The conventional frost protection function only seeks to prevent freezing of the heating pipe in consideration of the low thermal insulation effect of existing buildings. However, the risk of the heating wave is reduced due to the improved insulation effect with the exterior of recent buildings. On the other hand, there is a need to prevent freezing of hot water pipes because the freezing of hot water pipes frequently occurs even in the cold weather in winter, resulting in inconvenience in using hot water.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings, and a method of preventing freezing of boiler heating piping and hot water piping according to the present invention will be described in detail.

도 1은 일반적인 가스보일러의 동작을 위한 개략적인 구성도이다.1 is a schematic block diagram for operation of a general gas boiler.

먼저 도 1을 참조하여, 본 발명인 보일러 난방배관 및 온수배관의 동파방지방법이 이용될 수 있는 보일러의 구성을 설명한다.First, referring to FIG. 1, the construction of a boiler in which boiler heating piping and a method of preventing freezing of hot water piping can be used will be described.

콘트롤러(100)는 보일러의 전반적인 작동을 제어하도록 원칩마이콤을 포함하여 이루어진 것으로서, 점화장치를 제어하여 보일러의 가동을 가능하게 하고 화염감지센서를 통해 착화상태를 감지함으로써 불착화시 가스공급중단 등 안전제어를 할 뿐만 아니라 보일러의 최적제어를 위해 센서입력부를 통해 각종 센서로부터 보일러의 상태정보를 입력받아 보일러의 작동상태 및 외부환경을 고려한 최적의 제어를 하도록 하는 작용을 한다. 특히, 본 발명에 따라 난방수 온도센서(150)에서 감지된 난방수 온도를 입렵받아 기 설정된 온도와 비교하여 삼방밸브(120)를 제어함으로써, 난방배관 및 온수배관의 동파를 방지할 수 있게 한다.The controller 100 includes a one-chip microcomputer for controlling the overall operation of the boiler. The controller 100 controls the ignition device to enable operation of the boiler, and detects the ignition state through the flame detection sensor. In addition to the control, it also receives the status information of the boiler from various sensors through the sensor input part for optimal control of the boiler, and performs an optimal control considering the operation state of the boiler and the external environment. In particular, according to the present invention, the heating water temperature sensed by the heating water temperature sensor 150 is compared with a predetermined temperature to control the three-way valve 120, thereby preventing the heating pipe and the hot water pipe from being frozen .

난방열교환기(110)에서는 착화상태의 버너로부터 열에너지를 공급받아 난방수와 열교환이 이루어지며, 급탕열교환기(140)에서는 보일러의 온수모드 작동시 난방수와 직수간에 열교환이 이루어 진다.In the heating heat exchanger 110, heat energy is supplied from the burner in the ignited state and heat exchange is performed with the heating water. In the hot water heat exchanger 140, heat exchange is performed between the heating water and direct water in the hot water mode operation of the boiler.

삼방밸브(120)는 콘트롤러(100)의 제어를 받아 난방모드 또는 온수모드로 보일러의 작동을 가능하게 한다. 보일러가 난방모드로 작동하게 되면, 난방열교관기(110)에서 가열된 난방수가 순환펌프(140)에 가동으로 삼방밸브(120)를 통해 난방배관(200)으로 공급되고 다시 환수되어 팽창태크(180)를 거쳐 순환하게 된다. 한편, 보일러가 온수모드로 작동하게 되면, 난방수는 난방열교환기(110), 삼방밸브(120), 급탕열교환기(130) 및 순환펌프(140)를 포함하는 폐회로를 순환하게 된다.The three-way valve 120 enables the operation of the boiler in the heating mode or the hot water mode under the control of the controller 100. When the boiler is operated in the heating mode, the heating water heated in the heating device 110 is supplied to the circulation pump 140 through the three-way valve 120 to the heating pipe 200 and is returned to the expansion pipe 180 ). On the other hand, when the boiler operates in the hot water mode, the heating water circulates through the closed circuit including the heat exchanger 110, the three-way valve 120, the hot water heat exchanger 130 and the circulation pump 140.

도 2는 본 발명에 따른 보일러 난방배관 및 온수배관의 동파방지방법에 대한 흐름도이다. 도 2를 참조하여, 본 발명인 난방배관 및 온수배관의 동파방지방법을 설명한다.2 is a flowchart illustrating a method of preventing freezing of boiler heating piping and hot water piping according to the present invention. Referring to FIG. 2, a method of preventing freezing of a heating pipe and a hot water pipe according to the present invention will be described.

사용자에 의해 보일러가 외출모드로 설정된 경우에 콘트롤러(100)는 먼저 보일러를 정지상태로 동작시킨다. 즉, 버너(160)로 공급되는 연료를 차단하여 연소를 중지시킴과 아울러 순화펌프(140)의 작동을 정지시켜 보일러내 수관뿐만 아니라 난방배관(200)내의 관수의 순환을 정지 상태로 유지하고 있게 된다.When the boiler is set to the outgoing mode by the user, the controller 100 first operates the boiler in a stopped state. That is, the fuel supplied to the burner 160 is shut off to stop the combustion and the operation of the purifying pump 140 is stopped to keep the circulation of the water in the heating pipe 200 as well as the water pipe in the boiler in a stopped state do.

이와 같은 상태에서 콘트롤러(100)는 주기적으로 난방수 온도센서(150)의 감지온도를 체크하여 기 설정된 동파방지 설정온도와 비교하게 된다. 여기서 기 설정된 동파방지 설정온도는 일반적으로 배관내의 관수가 얼을 수 있는 온도조건으로 설정함이 바람직하다.In this state, the controller 100 periodically checks the detected temperature of the heating water temperature sensor 150 and compares the detected temperature with the predetermined freezing prevention preset temperature. Here, it is preferable that the predetermined freezing prevention presetting temperature is set to a temperature condition in which water in the piping can generally be frozen.

상기 온도 비교결과 난방수 온도가 동파방지 설정온도보다 높으면 계속하여 난방수 온도를 체크하고, 동파방지 설정온도보다 낮으면 콘트롤러(100)는 삼방밸브(120)를 온수모드로 전환시키고 버너(160)에 연료를 공급하여 연소시켜 열을 발생시킴과 아울러 순환펌프(140)를 작동시켜 난방수로 하여금 난병열교환기(110)에서 열을 흡수하도록 하여 난방수 온도를 상승시키고, 가열된 난방수를 순환펌프(140), 난방열교환기(110), 삼방밸브(120) 및 급탕열교환기(130)를 포함하는 폐회로를 순환하게 한다. If the heating water temperature is higher than the freezing prevention setting temperature, the controller 100 continues to check the heating water temperature. If the temperature is lower than the freezing prevention setting temperature, the controller 100 switches the three-way valve 120 to the hot water mode, The circulating pump 140 is operated to heat the circulating oil heat exchanger 110 to heat the heating water to raise the temperature of the heating water, The circulation loop including the pump 140, the heat exchanger 110, the three-way valve 120, and the hot water heat exchanger 130 is circulated.

이때, 급탕열교환기(130)에서는 가열된 난방수로부터 온수배관(210)으로 열전달이 이루어져 온수배관(210)의 동파를 방지할 수 있게 된다.At this time, heat is transferred from the heated water to the hot water pipe 210 in the hot water heat exchanger 130, thereby preventing the hot water pipe 210 from being frozen.

이후 보일러 연소행정으로 난방수가 기 설정된 연소정지 설정온도에 도달하면 콘트롤러(100)는 연료를 차단하여 소화행정을 수행하고 삼방밸브(120)를 다시 난방모드로 전환시키게 된다. Then, when the heating water reaches a preset burn-up stop set temperature in the boiler combustion stroke, the controller 100 cuts off the fuel to perform the extinguishing stroke and to switch the three-way valve 120 to the heating mode again.

여기서 상기 삼방밸브를 난방모드로 전환하기 위한 기 설정된 연소정지 설정온도는 상기 순환펌프(140), 난방열교환기(110), 삼방밸브(120) 및 급탕열교환기(130)를 포함하는 폐회로에서 상승시킬 수 있는 최대온도로 설정함이 바람직하다.The predetermined combustion stop set temperature for switching the three-way valve to the heating mode is set to a predetermined value in the closed loop including the circulation pump 140, the heat exchanger 110, the three-way valve 120 and the hot water heat exchanger 130 It is preferable to set the temperature to the maximum possible value.

상기 소화행정과 삼방밸브(120)를 난방모드로 전환된 이후에는 보일러는 연소행정을 수행하지 않고, 순환펌프(140) 만이 가동되어 가열된 난방수가 난방배관(200)을 통해 순환되므로 난방배관(200)의 동파를 방지할 수 있게 된다.After the fire extinguishing and the three-way valve 120 are switched to the heating mode, the boiler does not perform the combustion stroke and only the circulation pump 140 is operated, and the heated water is circulated through the heating pipe 200, Can be prevented.

따라서, 이와 같은 방법을 실시하면 기존 난방배관 동파방지 기능과 비교할 때 비슷한 연료를 사용하여 난방배관 뿐만 아니라 온수배관까지도 동파를 방지할 수 있게 된다.Therefore, by using this method, it is possible to prevent the freezing of not only the heating pipe but also the hot water pipe by using a similar fuel as compared with the function of preventing the freezing of the existing heating pipe.

또한, 바람직하게는 소화행정 후 일정시간, 즉 난방배관의 동파방지를 위한 난방수의 순환이 충분히 이루어질 수 있는 시간이 경과하게 되면 순환펌프(140)의 가동을 정지하여 보일러를 정지상태로 되돌려 놓는 단계를 포함할 수 있다.
In addition, preferably, when a time after the digestion process, that is, a sufficient time for circulation of the heating water for preventing the freezing of the heating pipe, is elapsed, the operation of the circulation pump 140 is stopped to return the boiler to the stopped state Step < / RTI >
