Description
본 발명은 동절기 외출시 온수보일러의 배관이 동파되는 것을 방지하기 위한 온수보일러의 동파방지장치 및 그 방법에 관한 것으로, 더욱 상세하게는 원칩 마이컴의 온도센서에 의해 외기 온도를 감지하고 그 온도에 따라 순환펌프의 작동시간 간격을 결정하게 되고, 이 순환펌프에 의해 일정시간 간격으로 유입되는 관수온도를 원칩 마이컴의 관수온도센서를 통해 동파온도를 감지하여 보일러를 일정시간동안 가동함으로써 관내의 내부온도를 상승시켜 동파를 방지하도록 하는 온수보일러의 동파방지장치 및 그 방법에 관한 것이다.The present invention relates to a freeze protection device and a method of freezing of the hot water boiler to prevent the freezing of the pipe of the hot water boiler when going out in winter, more specifically, by sensing the temperature of the outside air by the temperature sensor of the one-chip microcomputer The operating time interval of the circulating pump is determined and the water temperature introduced by the circulating pump at regular time intervals is sensed by the water temperature sensor of the one-chip microcomputer to operate the boiler for a certain period of time. The present invention relates to a freeze protection apparatus and a method of a hot water boiler to prevent freezing.
도 1은 종래 보일러의 구성일례를 나타내는 도면이다.1 is a view showing an example of the configuration of a conventional boiler.
보일러는 난방시 순환펌프(10)에 의해 내부관수를 강제순환시켜 난방열교환기(12)에서 버너(14)의 연소열을 흡수하여 온도를 상승시키고, 삼방변(16)의 작동에 따라 난방배관(18)으로 공급하여 실내난방에 이용할 수 있도록 하는 한편 온수사용시에는 보일러 내부의 내부관수를 순환시켜 난방열교환기에서 흡수된 열을 온수열교환기(20)로 공급하여 직수입구(22)로 유입된 직수가 온수열교환기(20)가 가지고 있던 열을 흡수하도록 하여 온수출구(24)로 따뜻한 온수를 공급하도록 하는 작용을 한다.The boiler forcibly circulates the internal water by the circulation pump 10 during heating to absorb the combustion heat of the burner 14 in the heating heat exchanger 12 to increase the temperature, and the heating pipe 18 according to the operation of the three-way toilet 16. ) To be used for indoor heating, while the hot water is used, the internal water inside the boiler is circulated to supply heat absorbed from the heating heat exchanger to the hot water heat exchanger 20 to supply the hot water introduced into the direct inlet 22. The heat exchanger 20 serves to absorb the heat it has to act to supply warm hot water to the hot water outlet (24).
이와 같은 보일러에서 콘트롤러(26)는 외출시 온도센서(28)를 통해 내부관수의 온도를 감지한 결과 내부관수가 동파방지설정온도, 즉 관수의 온도가 특정온도 이하로 내려갈 때 보일러의 동파방지를 위해 보일러가 자동으로 가동되도록 설정한 온도, 이하로 내려가는 것으로 감지되면 보일러를 가동시켜 내부관수의 온도를 상승시키고 이어 설정된 일정 온도 이상이 되면 보일러를 정지시키는 동파방지기능을 구비하고 있다.In such a boiler, the controller 26 detects the temperature of the internal irrigation through the temperature sensor 28 when going out, and as a result, the internal irrigation of the boiler is prevented when the internal irrigation is set at a freezing prevention temperature, that is, the temperature of the irrigation falls below a specific temperature. If it is detected that the boiler is automatically lowered to the set temperature or lower, the boiler is operated to raise the temperature of the internal irrigation and then stop the boiler when the set temperature is higher than the set temperature.
그렇지만, 이러한 종래 동파방지기능은 콘트롤러(26)가 내부관수의 온도만을 감지하여 보일러를 가동시키도록 되어 있는데, 겨울철에 동파되는 경우를 살펴볼 때 외출시 보일러를 정지시키면 내부관수가 순환되지 않고 정지된 상태라 갑작스럽게 기온이 저하된다거나 산간지역이나 해안지역 등 주위환경에 의해 보일러의 내부와 외부의 온도차가 심해 내부관수의 온도변화에 따른 동파방지기능이 작동되기도 전에 외부관수가 얼어 관수가 순환되지 못하게 되므로 보일러가 동파방지를 위해 작동하여도 배관이 동파되는 경우가 많았다.However, the conventional freeze protection function is to operate the boiler by detecting the temperature of the internal irrigation only in the controller 26, when the boiler is stopped when going out in winter, the internal irrigation is stopped without circulation. As the temperature drops suddenly or the temperature difference between the inside and outside of the boiler is severe due to the surrounding environment such as mountainous area or coastal area, the external water is frozen and the water is not circulated before the freeze protection function is activated due to the temperature change of the internal water. In many cases, the pipes were frozen even though the boiler was operated to prevent freezing.
따라서, 동절기 외출시 보일러를 정지시키면 관수가 순환되지 않고 정지된 상태라 종래의 동파방지기능으로는 갑작스런 기온저하나 주위환경에 따라 내부와 외부의 온도차가 심할 경우 상기 동파방지기능이 동작되기도 전에 외부관수가 얼어서 배관이 동파될 수 있는 문제점이 있었다.Therefore, if you stop the boiler when you go out in winter, the water is stopped without circulation. In the conventional freeze protection function, if the temperature difference between the inside and the outside is severe depending on the sudden temperature drop or the surrounding environment, There was a problem that the pipe can be frozen because the water is frozen.
본 발명은 상기한 문제점을 개선하기 위하여 발명한 것으로, 보일러의 콘트롤러인 원칩 마이컴에 설치된 외기온도센서에 의해 주위환경의 온도를 감지하고, 감지된 온도에 따라 일정한 주기로 순환펌프를 가동시켜 내부수관으로 외부관수를 유입시킨 후 외부관수가 유입된 관수온도를 감지하여 동파온도 이하인 경우 보일러를 가동하여 관내의 수온을 상승시킴으로써 동파를 방지하는 한편, 다시 상승된 관내의 내부온도가 설정된 일정온도가 되면 보일러를 정지시키도록 된 온수보일러의 동파방지장치 및 그 방법을 제공하고자 함에 발명의 목적이 있다. The present invention has been invented to improve the above problems, by sensing the temperature of the surrounding environment by the air temperature sensor installed in the one-chip microcomputer controller of the boiler, and operates the circulation pump at regular intervals according to the detected temperature to the internal water pipe After the external water flows in, the external water flow detects the water inflow temperature, and if it is below the freezing temperature, it operates the boiler to raise the water temperature in the pipe to prevent freezing, and when the internal temperature in the raised pipe reaches the set temperature, the boiler An object of the present invention to provide a freeze protection device and a method of a hot water boiler to stop the.
상기한 목적을 실현하기 위한 본 발명에 따른 온수보일러의 동파방지장치는, 보일러의 전반적인 작동을 제어하도록 원칩마이콤으로 이루어진 콘트롤러, 내부수관내의 관수온도를 감지하여 상기 콘트롤러에 입력시키는 관수온도센서, 상기 내부관수를 순환시켜 열교환을 촉진시키도록 콘트롤러에 의해 제어되는 순환펌프, 메인버너에 착화에너지를 공급하도록 콘트롤러에 의해 제어되는 점화장치 그리고 메인버너의 착화상태를 감지하는 화염감지센서를 포함하여 이루어져, 관수온도에 따라 메인버너를 가동하여 동파를 방지할 수 있도록 된 온수보일러의 동파방지장치에 있어서, 상기 콘트롤러의 입력단 일측에는 외기온도를 감지하여 입력시키는 외기온도감지센서가 연결되고, 상기 콘트롤러는 외기온도가 사전에 설정된 온도보다 낮으면 순환펌프를 가동시켜 관수를 순환시키고나서 관수온도가 사전에 설정된 동파방지온도보다 낮으면 보일러를 가동하도록 하는, 외기온도에 따른 동파방지모드를 수행하도록 이루어진 것을 특징으로 한다.In order to achieve the above object, the freeze protection apparatus of a hot water boiler according to the present invention includes a controller consisting of a one-chip microcomputer to control the overall operation of a boiler, and a watering temperature sensor for sensing the watering temperature in the internal water pipe and inputting the same to the controller. It includes a circulating pump controlled by the controller to circulate the inner water to promote heat exchange, an ignition device controlled by the controller to supply ignition energy to the main burner, and a flame detection sensor for detecting the ignition state of the main burner. In the freezing prevention device of a hot water boiler which can prevent freezing by operating the main burner according to the watering temperature, an outside air temperature sensor is connected to one side of the input terminal of the controller to sense and input the outside air temperature, and the controller is Circulation pump when the outside temperature is lower than the preset temperature After operating the pump to circulate the irrigation water is characterized in that it is configured to perform the freeze protection mode according to the outside temperature to operate the boiler when the watering temperature is lower than the preset freeze protection temperature.
또한 본 발명에 따른 온수보일러의 동파방지방법은, 설정된 동파방지모드에서 외기온도를 주기적으로 감지하는 외기온도감지단계, 상기 외기온도감지단계에서 감지된 외기온도를 사전에 설정된 순환펌프구동온도와 비교하는 단계, 상기 비교단계에서 외기온도가 순환펌프구동온도보다 낮은 것으로 판단되면 순환펌프를 작동시키는 단계, 상기 순환펌프작동 이후 관수온도를 사전에 설정된 동파방지설정온도와 비교하는 단계, 상기 비교단계에서 관수온도가 동파방지설정온도보다 낮은 것으로 판단되면 관수온도가 사전에 설정된 보일러작동중지온도가 될 때까지 보일러를 작동시키는 단계로 이루어져 있다.In addition, the freeze protection method of the hot water boiler according to the present invention, the outside air temperature sensing step of periodically detecting the outside air temperature in the set freeze protection mode, the outside air temperature detected in the outside air temperature detection step is compared with the pre-set circulation pump driving temperature In the comparing step, if it is determined that the outside air temperature is lower than the circulating pump driving temperature, operating the circulating pump, comparing the irrigation temperature after the circulating pump operation with a preset freeze protection set temperature, in the comparing step If it is determined that the irrigation temperature is lower than the freeze protection set temperature, the boiler is operated until the irrigation temperature reaches a preset boiler operation stop temperature.
이하 본 발명의 바람직한 일실시예에 대한 구성 및 작용을 예시도면에 의거하여 상세히 설명한다.Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 일실시예에 따른 개략적 구성도를 나타낸다.2 shows a schematic configuration diagram according to an embodiment of the present invention.
콘트롤러(26)는 보일러의 전반적인 작동을 제어하도록 원칩마이콤을 포함하여 이루어진 것으로서, 점화장치(30)를 제어하여 보일러의 가동을 가능하게 하고 화염감지센서(32)를 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 외기온도를 감지하고 그에 따라 동파방지기능을 수행함으로써 외기온도가 급격하게 저하되더라도 수관의 동파를 방지할 있도록 하는 기능을 구비하고 있다.The controller 26 includes one chip microcomputer to control the overall operation of the boiler. The controller 26 controls the ignition device 30 to enable the boiler to operate and detects the ignition state through the flame detection sensor 32 to prevent incombustibility. In addition to safety control such as gas supply interruption, it also functions to optimize the boiler's operating status and external environment by receiving the boiler's status information from various sensors through the sensor input unit for optimal control of the boiler. In particular, the present invention is provided with a function to prevent freezing of water pipes by sensing the outside temperature and performing a freezing prevention function according to the present invention even if the outside air temperature is suddenly lowered.
관수온도센서(34)는 보일러 외측으로 연결되는 난방배관(18)과 같은 외부수관으로부터 유입되는 관수가 난방열교환기(12)로 유입되기전의 수관에 설치되어, 난방배관(18)과 같은 외부수관내의 관수온도를 감지하여 콘트롤러(26)로 입력시키는 센서이다. 이는 보다 외기온도에 직접적인 영향을 받는 부위의 관수온도를 감지하여 그러한 관수온도가 동파방지설정온도 이하로 떨어지는지 여부를 감지하여 보일러의 작동을 제어하기 위함이다.The watering temperature sensor 34 is installed in the water pipe before the water flowing from the external water pipe, such as the heating pipe 18 connected to the outside of the boiler to the heating heat exchanger 12, the inside of the external water pipe, such as the heating pipe 18 The sensor detects the watering temperature of the input to the controller (26). This is to control the operation of the boiler by detecting the irrigation temperature of the part directly affected by the outside air temperature and detecting whether the irrigation temperature falls below the freeze protection set temperature.
외기온도센서(36)는 실외의 온도를 감지하여 콘트롤러(26)로 입력시키는 작용을 하는 센서로서, 콘트롤러(26)가 상기 외기온도센서(36)에 의해 감지되는 실외의 온도와 온도센서(28)에 의해 감지되는 내부관수의 온도를 감안하여 보일러의 작동을 제어할 수 있도록 함으로써 갑작스럽게 실외의 기온이 변화하여 동파가 예상될 때 이를 감안하여 보일러의 작동을 제어할 수 있도록 하기 위한 것이다. 이를 위해 외기온도센서(36)는 보일러 외부에 설치되어지며, 특히 실외에 설치되어 외기를 감지하도록 함으로써 외기변화를 신속하게 감지하여 보일러의 작동제어에 이용하도록 함이 바람직하다.The outdoor temperature sensor 36 is a sensor that senses the outdoor temperature and inputs it to the controller 26. The outdoor temperature and the temperature sensor 28 sensed by the outdoor air temperature sensor 36 by the controller 26. By controlling the boiler's operation in consideration of the temperature of the internal irrigation detected by), it is to allow the boiler's operation to be controlled by taking into account the expected freezing frequency due to a sudden change in outdoor temperature. To this end, the outside air temperature sensor 36 is installed outside the boiler. In particular, the outside air temperature sensor 36 is preferably installed outside to detect outside air so as to quickly detect the outside air change and use it for the operation control of the boiler.
도 3은 본 발명에 따른 동파방지방법을 설명하기 위한 흐름도이다.3 is a flowchart illustrating a freezing prevention method according to the present invention.
사용자에 의해 보일러가 외출모드로 설정된 경우에 콘트롤러(26)는 먼저 보일러를 정지상태로 동작시킨다. 즉, 버너(14)로 공급되는 연료를 차단하여 연소를 중지시킴과 아울러 순환펌프(10)의 작동을 정시시켜 보일러내 수관뿐만 아니라 난방배관(18)내의 관수의 순환을 정지된 상태로 유지하고 있게 된다.When the boiler is set to go out mode by the user, the controller 26 first operates the boiler in a stopped state. That is, the fuel supplied to the burner 14 is interrupted to stop combustion, and the operation of the circulation pump 10 is indicated to maintain the circulation of the water in the heating pipe 18 as well as the water pipe in the boiler. Will be.
이와같은 상태에서 콘트롤러(26)는 주기적으로 외기온도센서(36)의 감지온도를 체크하여 사전에 설정되어 있는 순환펌프구동온도와 비교하여 순환펌프를 구동할지 여부를 판단하게 된다.In such a state, the controller 26 periodically checks the sensing temperature of the outside air temperature sensor 36 to determine whether to drive the circulating pump by comparing with a preset circulating pump driving temperature.
이때 외기온도가 순환펌프구동온도보다 낮은 것으로 판단되면 순환펌프를 작동시켜 관수를 순환시킴으로써 관수가 동결되는 것을 방지한다. 이와 같은 순환펌프(10)의 동작은 외기온도가 순환펌프구동온도보다 낮고 관수온도가 동파방지설정온도보다 낮은 동안에는 일정 주기로 반복시킨다.At this time, if it is determined that the outside temperature is lower than the circulating pump driving temperature, by operating the circulating pump to circulate the water to prevent the water freezing. The operation of the circulation pump 10 is repeated at regular intervals while the outside air temperature is lower than the circulation pump driving temperature and the irrigation temperature is lower than the freeze protection set temperature.
그러다가 외기온도가 더욱 낮아져 관수온도센서(34)에 의해 감지되는 관수온도가 콘트롤러(26)에 사전에 설정되어 있던 동파방지설정온도 이하로 떨어지는 것으로 감지되면 순환펌프(10)의 구동에 의한 관수의 순환만으로 동파방지가 어려운 것으로 판단하여 콘트롤러(26)는 버너(14)에 연료를 공급하여 연소시켜 열을 발생시킴과 아울러, 순환펌프(10)를 작동시켜 내부관수로 하여금 난방열교환기(12)에서 버너(14)의 연소열을 흡수하도록 하여 온도를 상승시키고 이를 난방배관(18)으로 전달하도록 한다. 이와 같이 관수온도가 동파방지설정온도 이하로 떨어지는 경우에는 보일러를 작동시켜 내부수관 뿐만 아니라 외부수관의 온도를 상승시킴으로써 동파를 방지하도록 한다.Then, when the outside air temperature is further lowered and the water temperature detected by the water temperature sensor 34 falls below the freezing protection preset temperature previously set in the controller 26, the water flow by the driving of the circulation pump 10 is detected. It is judged that it is difficult to prevent freezing by circulating only, so that the controller 26 supplies fuel to the burner 14 to burn it to generate heat, and operates the circulating pump 10 to allow internal watering to be carried out in the heating heat exchanger 12. The combustion heat of the burner 14 is absorbed to raise the temperature and transfer it to the heating pipe 18. As such, when the water temperature falls below the freezing protection temperature, the boiler is operated to prevent freezing by raising the temperature of the external water pipe as well as the internal water pipe.
그리고 보일러의 작동으로 인해 관수온도가 콘트롤러(26)에 사전에 설정된 일정온도보다 충분히 상승된 것으로 판단되면 보일러의 작동을 중지시켜 연료의 낭비를 방지한다.And if it is determined that the irrigation temperature due to the operation of the boiler is sufficiently higher than the predetermined temperature set in advance in the controller 26 to stop the operation of the boiler to prevent waste of fuel.
이와 같이 외출모드시 콘트롤러(26)의 동파방지기능은 콘트롤러(26)가 외기온도를 체크하여 이를 순환펌프구동온도와 관수온도 그리고 동파방지설정온도를 감안하여 순환펌프(10)와 보일러의 작동을 제어하는 동작을 반복함으로써 달성하게 된다.As such, the freeze protection function of the controller 26 in the outgoing mode allows the controller 26 to check the outside air temperature and to operate the circulation pump 10 and the boiler in consideration of the circulation pump driving temperature, the irrigation temperature, and the freeze protection set temperature. This is accomplished by repeating the controlling operation.
상기한 바와 같이 보일러와 연결된 수관은 기온이 급속히 저하됨에 따라 구간별로 온도가 다르게 되는데, 즉 바닥에 매설된 외부수관, 보일러 내부의 내부수관 그리고 외부수관과 내부수관의 연결부로 나뉘어지게 되며, 특히 보일러는 주로 외부에 있는 관계로 수관의 수온 저하는 연결부, 내부수관, 외부수관 순으로 이루어지므로 단순히 내부수관의 온도를 감지하여 보일러를 가동할 경우 연결부의 동결로 기존의 동파방지 구조로는 효과를 얻지 못하게 된다. 그러나 본 발명에서는 수관의 온도를 감지하기 전에 외기의 온도를 감지하고 일정한 외기 온도일 경우 순환펌프를 가동하여 유입되는 수관의 수온을 실질적으로 감지하여 보일러를 구동하게 되므로 동파를 방지하는데 더욱 효과를 얻을 수 있다.As described above, the water pipe connected to the boiler has a different temperature for each section as the temperature decreases rapidly. That is, the water pipe is divided into an external water pipe buried at the bottom, an internal water pipe inside the boiler, and a connection between the external water pipe and the internal water pipe. Since the water temperature is lowered in the order of connection part, internal water pipe, and external water pipe in order to be outside, simply detect the temperature of the internal water pipe and operate the boiler by freezing the connection. I can't. However, in the present invention, since the temperature of the outside air is sensed before the temperature of the water pipe is sensed, and a constant outside temperature is performed, the boiler is driven by substantially detecting the water temperature of the incoming water pipe by operating a circulating pump, thereby obtaining a further effect in preventing freezing. Can be.
