Specifically, by establishing a system capable of communicating between a room cone equipped with a wireless communication module and an integrated server, a separate outside air temperature sensor may be installed. Receives outside temperature information from the integrated server without the need to compensate the set temperature according to the outside temperature to adjust the amount of heat supplied and to prevent the formation of icicles in the exhaust pipe even in sub-zero temperatures. Also relates to a compensation control method.
온돌난방은 크게 개별난방방식, 지역난방방식과 중앙난방방식으로 나눌 수 있다. 온돌난방에서 이상적인 제어가 이루어지려면 건물의 열획득(Heat gain)과 열손실(Heat loss)이 동일해야 한다. 열획득, 열손실 과정은 동적(dynamic)인 프로세스로서 외기온, 태양 일사, 침기, 내부발열 등에 의해 수시로 변화하기 때문에 실내에 공급되는 열량에 대한 제어가 필요하다.Ondol heating can be divided into individual heating method, district heating method and central heating method. In order to achieve ideal control in the heating of the ondol, the building's heat gain and heat loss must be equal. The process of heat acquisition and heat loss is a dynamic process and changes frequently from outside temperature, solar radiation, invasion, internal heat generation, and so on, and therefore, it is necessary to control the amount of heat supplied to the room.
개별난방의 경우 난방공급수의 온도는 계절별로 기준을 달리 설정하여 공급하며, 겨울철의 경우 60-80℃로 설정되는 경우가 일반적이다. 이는 계절별로 외기온의 영향을 고려한 것이기는 하나 동일한 계절 기간에서도 외기온 변화폭이 공급난방수의 온도설정에 미치는 영향을 고려한 것은 아니며, 낮과 밤, 남향과 북향, 건물의 특성(외기온에 대한 반응 특성) 등을 고려하지 않았기 때문에 과열현상이 발생하고 에너지 낭비를 초래하는 경우가 많다는 문제점이 있다.In the case of individual heating, the temperature of the heating water supply is set differently according to the season, and in winter, it is generally set to 60-80 ℃. This is due to the influence of outside temperature by season, but does not take into account the effect of the change in outside temperature on the temperature setting of supply and heating water during the same season period. Since it is not considered, there is a problem that overheating occurs and causes a lot of energy waste.
이러한 문제점을 해결하기 위해 종래 공개특허 제10-1109648호에서는 온수가 공급되는 공급라인; 상기 공급라인으로부터 각 방으로 분기되어 상기 온수의 잠열이 해당 방과 열교환되도록 하는 온수관로; 상기 온수관로와 각각 연통되어 열교환이 끝난 온수가 환수되는 환수라인; 실외의 공기온도를 측정하기 위해 마련된 외기온도센서; 상기 외기온도센서로부터 외기 온도를 제공받아 그에 따른 제어신호를 출력하는 제어부; 상기 공급라인 또는 환수라인에 설치되며 상기 제어부로부터 제어신호를 받아 관 내부를 흐르는 상기 온수의 유량을 조절하는 가변유량밸브;를 포함하는 외기온도 연동식 유량제어장치를 제시한 바 있다.In order to solve this problem, the prior art Patent Publication No. 10-1109648 has a supply line for supplying hot water; A hot water pipe branch branched from the supply line to each room so that latent heat of the hot water is exchanged with the corresponding room; A return line communicating with each of the hot water pipe passages and returning hot water after heat exchange; An outside air temperature sensor provided to measure an outdoor air temperature; A controller for receiving an outside temperature from the outside temperature sensor and outputting a control signal according to the outside temperature; The external air temperature-linked flow control device including a; variable flow valve installed in the supply line or the return line to control the flow rate of the hot water flowing through the tube in response to a control signal from the controller.
한편, 일반적으로 보일러의 경우, 실외에서 급기배관을 통해 유입된 공기는 송풍기에 의해 연료와 함께 버너에 공급되고, 버너에서 연소로 인해 발생된 배기가스는 열교환기에서 순환펌프에 의해 압송되는 난방수와 열교환을 한 다음, 배기통을 통해 보일러 외부인 대기 중으로 방출된다.On the other hand, in the case of a boiler in general, the air introduced through the air supply pipe in the outdoors is supplied to the burner with the fuel by the blower, and the exhaust gas generated by the combustion in the burner is pumped by the circulation pump in the heat exchanger After heat exchange with, it is discharged into the atmosphere through the exhaust pipe to the outside of the boiler.
상기 배기가스 중에는 상당량의 수분(H2O)이 포함되어 있는데, 통상적으로 배기가스의 온도는 100도 이상이기 때문에 배기가스 속에 포함된 수분은 응축되지 못하고 수증기 상태로 배기통을 통해 방출된다.The exhaust gas contains a considerable amount of water (H 2 O). Since the temperature of the exhaust gas is typically 100 degrees or more, the moisture contained in the exhaust gas is not condensed and is discharged through the exhaust tube in the form of water vapor.
그러나 겨울철 등과 같이 외기 온도가 매우 낮은 경우에는 배기통 말단부의 온도가 매우 낮아져서 배기가스가 노점온도(배기가스 속에 포함된 수증기가 응결되기 시작하는 온도로서 통상 40~55도)이하로 되는 경우가 있고, 이 경우에는 배기통 말단부에서 수증기가 응결된다.However, when the outside air temperature is very low, such as in winter, the temperature at the end of the exhaust tube is very low, and the exhaust gas may be lower than the dew point temperature (40 to 55 degrees as a temperature at which water vapor contained in the exhaust gas starts to condense). In this case, water vapor condenses at the end of the exhaust tube.
이 경우 외기온도가 영하인 겨울에는 상기 배기통 말단부에서 응결된 수증기가 결빙되어 고드름이 형성되는데, 이러한 고드름은 미관상 매우 좋지 않을 뿐만 아니라 고층 건물 상층부에서 고드름이 낙하하는 경우에는 인적 또는 물적 피해가 발생하는 문제점이 있다.In this case, in winter when the outside temperature is below freezing, the water vapor condensed at the end of the exhaust tube freezes to form icicles. There is a problem.
이러한 문제점을 해결하기 위해 종래 등록특허 제10-0805551호에서는 보일러가 가동되어 연소행정이 이루어지는 단계; 외기온도센서로부터 측정된 외기온도가 미리 설정된 온도 이하인지 여부를 판단하는 단계; 상기 측정된 외기온도가 설정된 온도 이하인 경우 삼방밸브를 온수위치로 전환하는 단계; 난방수 배관온도가 미리 설정된 온도에 도달한 경우 버너의 소화행정을 실시하는 단계; 순환펌프 및 송풍기를 작동시켜 주열교환기에서 열교환이 일어나 더운 공기가 배기통를 통해 배출되는 단계;로 이루어진 보일러 배기통의 응결방지 방법을 제시한 바 있다.Conventional Patent No. 10-0805551 in order to solve this problem is a step in which the combustion operation is performed by the boiler; Determining whether the outside air temperature measured by the outside air temperature sensor is equal to or less than a preset temperature; Switching the three-way valve to a hot water position when the measured outside temperature is below a set temperature; Performing a fire extinguishing stroke of the burner when the heating water pipe temperature reaches a preset temperature; The operation of the circulation pump and the blower to heat exchange in the main heat exchanger is the hot air is discharged through the exhaust pipe; the method for preventing the condensation of the boiler exhaust pipe consisting of.
상기한 종래 기술들은 공통적으로 외기온도 측정을 위해 별도의 외기온도감지센서를 외벽 또는 보일러의 급기구에 부착을 해야하고 보일러의 컨트롤러에 결선을 해야하는 등의 불편함이 있게 된다.The above-mentioned conventional techniques are inconvenient to attach a separate outside temperature sensor to the outside wall or the air supply of the boiler for measuring the outside temperature, and to connect to the controller of the boiler.

본 발명인 외부망을 이용한 보일러의 외기온도 보상제어 방법은 크게 (a)보일러(100)의 룸콘(110)을 통합서버(130)에 등록하는 단계; (b)통합서버(130)에서 외기온도 정보를 상기 룸콘(110)으로 전송하는 단계; 및 (c)상기 룸콘(110)에서 수신받은 외기온도 정보를 이용하여 보일러(100)에서 외기온도 보상제어를 수행하는 단계로 나뉘게 된다.The air temperature compensation control method of the boiler using the external network of the present invention is largely (a) registering the room cone 110 of the boiler 100 to the integrated server 130; (b) transmitting, by the integrated server 130, the outside temperature information to the room cone 110; And (c) performing outside temperature compensation control in the boiler 100 by using the outside temperature information received from the room cone 110.
먼저 룸콘(110)의 통합서버 등록단계를 살펴보면, 도 1에 도시된 바와 같이 가정내에 설치된 룸콘은 무선통신 모듈(111)을 탑재하고 있어 무선통신이 가능하며, 제품마다 고유번호가 입력되어 있다. Referring to the integrated server registration step of the roomcon 110 first, as shown in Figure 1, the roomcon installed in the home is equipped with a wireless communication module 111, wireless communication is possible, and a unique number is entered for each product.
그리하여 룸콘(110)이 가정내 설치된 무선공유기(120)와 접속이 되면 무선통신 통신을 이용하여 상기 고유번호를 송신하게 되고 상기 무선공유기는 이를 수신받아 다시 통합서버(130)로 송신하게 된다.Thus, when the room cone 110 is connected to the wireless router 120 installed in the home, the unique number is transmitted using wireless communication, and the wireless router receives the transmission and transmits the unique number to the integrated server 130 again.
통합서버(130)에서는 인증서버(131)와 데이터베이스(135)를 구비하고 있어, 전송받은 상기 고유번호를 분석하고 올바른 것인지 여부를 판단하는 인증 절차를 수행하고 인증이 완료되면 상기 고유번호를 데이터베이스(135)에 저장하게 된다. The integrated server 130 is provided with an authentication server 131 and the database 135, and performs the authentication procedure to analyze the received unique number and determine whether it is correct, and when the authentication is completed, the unique number is stored in the database ( 135).
통합서버(130)에서 외기온도 정보를 룸콘(110)에 전송하는 단계는 두 가지의 방법으로 가능하다.In the integrated server 130, the step of transmitting the outside temperature information to the room cone 110 may be performed in two ways.
첫째는 사용자 또는 설치자가 주소정보를 입력한 경우로, 사용자 또는 설치자는 스마트폰, PC, 노트북 등의 단말기(140)를 통해 통합서버(130)에 접속하여 상기 고유번호를 입력한 후 룸콘(110)이 설치된 지역의 주소정보를 입력하게 되고, 데이터베이스(135)에서 상기 고유번호와 함께 상기 주소정보가 저장된다. 이후 룸콘(110)에서 외기온도 보상제어 기능이 설정되면 전국 각 지역의 외기온도를 실시간 검색하여 업데이트 하는 서비스서버(132)에서 상기 룸콘(110)의 고유번호 및 주소정보를 검색하여 일정시간마다 해당 지역의 실시간 외기온도 정보를 상기 룸콘(110)으로 전송하게 된다.First, when a user or an installer inputs address information, the user or installer accesses the integrated server 130 through a terminal 140 such as a smartphone, a PC, a laptop, and inputs the unique number. ) Is inputted the address information of the installed area, and the address information is stored in the database 135 together with the unique number. After the air temperature compensation control function is set in the room cone 110, the service server 132 for real-time searching and updating the outside temperature of each region in the country searches for the unique number and address information of the room cone 110 at a predetermined time. Real-time outdoor temperature information of the area is transmitted to the room cone 110.
둘째는 사용자가 주소정보를 입력하지 않은 경우로, 통합서버(130)는 상기 룸콘(110)과 무선통신을 수행한 무선공유기(120)의 IP주소를 추출하여 한국인터넷 정보센터(krnic:http:// ) 등을 통해 대략적인 접속지역 파악하고 해당 위치정보를 데이터베이스(135)에 저장하게 된다. 이후 룸콘(110)에 외기온도 정보를 전송하는 과정은 상기한 방법과 동일하다.Second, when the user does not enter the address information, the integrated server 130 extracts the IP address of the wireless router 120 that has performed wireless communication with the room cone 110, and the Korea Internet Information Center (krnic: http: //) to determine the approximate connection area and the corresponding location information is stored in the database 135. Thereafter, the process of transmitting the outside temperature information to the room cone 110 is the same as the above-described method.
상기 단계를 거쳐 외기온도 정보를 수신받은 룸콘(110)은 상기 외기온도 정보를 RS485 등의 유선통신 방법으로 보일러(100)의 제어부(101)로 전송하여 외기온도에 따른 보상제어를 수행하게 된다.The room cone 110 receiving the outside temperature information through the above steps transmits the outside temperature information to the control unit 101 of the boiler 100 by a wired communication method such as RS485 to perform compensation control according to the outside temperature.
한편, 이상에서는 통합서버(130)에서 제어부(101)로 외기온도 정보가 전송되는 과정에서 룸콘(110)이 필수적 구성으로 제시되어 있으나, 상기 룸콘(110)은 위와 유사한 방법으로 외기온도 정보를 송수신 할 수 있는, 예를 들면 보일러에 부착된 패널부 등과 같은 모든 장치를 포함하는 것으로 이해되어야 한다.On the other hand, the room cone 110 is presented as an essential configuration in the process of transmitting the outside temperature information from the integrated server 130 to the control unit 101, the room cone 110 transmits and receives outside temperature information in a similar manner as above. It is to be understood that this includes all devices that can, for example, panel parts attached to the boiler.
상기 외기온도에 따른 보상제어는 종래기술에서 여러 형태로 제시되고 있는데, 여기서는 외기온도에 따라 공급되는 열량을 조절하여 에너지 효율을 높이기 위한 제어와 외기온도가 영하일 경우 배기통에 고드름 형성을 방지하기 위한 제어에 관한 실시예를 설명하기로 한다.Compensation control according to the outside temperature has been presented in various forms in the prior art, where the control to increase the energy efficiency by adjusting the amount of heat supplied according to the outside temperature and to prevent the formation of icicles in the exhaust case when the outside temperature is below zero An embodiment related to the control will be described.
먼저, 외기온도에 따라 공급되는 열량을 조절을 위해 유량제어 방식과 난방공급수 온도제어 방식이 모두 가능하다.First, both a flow control method and a heating supply water temperature control method are possible to adjust the amount of heat supplied according to the outside temperature.
도 2에 도시된 바와 같이, 외기온도 연동식 유량제어장치는 크게 공급관(210), 온수공급헤더(220), 온수관로(230), 온수환수헤더(240), 환수관(250)과 제어부(101), 가변유량밸브(260)를 포함하여 이루어 진다.As shown in Figure 2, the outside temperature interlock flow control device is largely supply pipe 210, hot water supply header 220, hot water pipe line 230, hot water return header 240, return pipe 250 and the control unit ( 101), the variable flow valve 260 is made.
상기 온수관로(230)는 상기 온수공급헤더(220)로부터 각 방으로 분기되어 상기 온수의 잠열이 해당 방과 열교환되도록 하는 구성으로써, 온수관로(230)를 따라 흐르는 과정에서 방바닥과 열교환하여 방바닥을 따뜻하게 데우고 그 후 온수는 식어서 온수환수헤더(240)를 통해 환수된다.The hot water pipe 230 is branched from the hot water supply header 220 to each room so that the latent heat of the hot water is heat-exchanged with the corresponding room, and heat exchanges with the floor in the process along the hot water pipe 230 to warm the floor. After warming, the hot water is cooled and returned through the hot water return header 240.
상기 제어부(101)는 룸콘(110)에서 출력되는 외기온도 정보를 제공받아, 외기온도에 따른 제어신호를 출력하여 상기 가변유량밸브(260)를 제어하게 된다.The control unit 101 receives the outside temperature information output from the room cone 110 and outputs a control signal according to the outside temperature to control the variable flow valve 260.
상기 가변유량밸브(260)는 공급관(210) 또는 환수관(250)에 설치된 것으로 상기 제어부(101)로부터 제어신호를 받으면 상기 공급관(210) 또는 환수관(250)의 내부를 흐르는 온수의 유량을 조절하게 된다. The variable flow valve 260 is installed in the supply pipe 210 or the return pipe 250 and receives a control signal from the control unit 101 to determine the flow rate of hot water flowing in the supply pipe 210 or the return pipe 250. Will be adjusted.
즉, 외기온도가 상승하게 되면 온수의 유량의 적어지도록 상기 제어부(101)는 상기 가변유량밸브(260)를 제어하는데, 적은 유량을 공급하기 때문에 공급온수의 유속이 느려져 열교환 시간이 보다 충분하게 되고 이에 따라 열효율이 높아지게 되는 것이다.That is, when the outside temperature rises, the control unit 101 controls the variable flow valve 260 so that the flow rate of the hot water decreases, and since the flow rate of the supplied hot water is slowed down because the small flow rate is supplied, the heat exchange time becomes more sufficient. As a result, the thermal efficiency is increased.
한편, 외기온도에 따른 난방공급수 온도제어방법은 제어부(101)가 룸콘(110)에서 출력되는 외기온도 정보를 제공받아, 기 설정된 외기온도에 따른 변화상수(K-factor) 값에 따라 난방공급수의 온도를 결정하여 난방제어가 이루어지는 것으로, 여기서 결정된 난방공급수 온도는 최대 80도로 제한되며 30도 미만이면 보일러 운전을 정지시킨다. 이로써 기존의 비례제어 방식에 비하여 불필요한 난방에너지 소비를 줄일 수 있게 된다.On the other hand, the heating supply water temperature control method according to the outside temperature is the control unit 101 receives the outside temperature information output from the room cone 110, the heating supply according to the change constant (K-factor) value according to the preset outside temperature The heating control is performed by determining the temperature of the water, where the determined heating water temperature is limited to a maximum of 80 degrees and stops the boiler operation if it is less than 30 degrees. As a result, unnecessary heating energy consumption can be reduced as compared to the existing proportional control method.
도 4는 일반적으로 사용되는 K-factor 값에 따른 외기온도와 난방공급수 설정온도와의 관계를 나타낸 그래프이며, K-factor는 외기온도에 따라 보상율을 적용하여 계산된 값으로 초기값 1로 설정되어 있으나, 설치자 또는 사용자에 의해 변경될 수 있다.4 is a graph showing the relationship between the ambient air temperature and the heating water supply temperature according to the commonly used K-factor value, the K-factor is a value calculated by applying the compensation rate according to the ambient temperature is set to the initial value 1 However, it can be changed by the installer or the user.
다음으로, 도 3을 참고하여 보일러의 배기통에 고드름 형성을 방지하기 위한 제어방법에 대하여 설명한다.Next, a control method for preventing icicle formation in the exhaust pipe of the boiler will be described with reference to FIG. 3.
먼저 보일러가 가동되어 연소행정이 이루어진다. 상기 룸콘(110)에서 제공된 외기온도가 배기통(360) 말단부에서 응결된 물을 결빙시킬 수 있는 온도인 0℃에 도달한 경우, 제어부(101)에서는 삼방밸브(390)를 온수위치로 전환하여 방바닥과의 열교환이 이루어지는 난방배관(310)측으로 난방수가 유입되는 것을 차단하고, 급탕열교환기(380)측으로 난방수가 흐르도록 한다. 이 경우 기존의 버너(330)에서 이루어지던 연소행정은 그 상태를 유지하게 된다First, the boiler is started and the combustion stroke is performed. When the outside air temperature provided from the room cone 110 reaches 0 ° C., which is a temperature at which the condensed water may freeze at the distal end of the exhaust container 360, the control unit 101 switches the three-way valve 390 to a hot water position to provide a room bottom. The heating water is prevented from flowing into the heating pipe 310 in which heat exchange with the heating pipe 310 is performed, and the heating water flows to the hot water supply heat exchanger 380. In this case, the combustion stroke made in the existing burner 330 is maintained in that state.
이 경우 난방수는 순환펌프(350)의 작동에 의해 순환펌프(350), 주열교환기(340), 삼방밸브(390), 급탕열교환기(380) 및 팽창탱크(370)로 이루어진 폐회로를 순환함으로써, 난방수는 반드시 팽창탱크(370)를 거치는 유로구조를 갖는 것이 바람직하다.In this case, the heating water circulates a closed circuit composed of the circulation pump 350, the main heat exchanger 340, the three-way valve 390, the hot water heat exchanger 380, and the expansion tank 370 by the operation of the circulation pump 350. , The heating water preferably has a flow path structure that passes through the expansion tank (370).
즉, 상기 팽창탱크(370)는 통상 4~8리터 정도의 난방수를 저장할 수 있고, 삼방밸브(390)를 온수위치로 전환한 상태에서 연소가 이루어지면 폐회로를 순환되는 난방수가 가열되어 상기 팽창탱크(370)는 배기통(360) 말단부의 결빙형성을 방지할 수 있는 열에너지를 축열하는 기능을 가지게 된다.That is, the expansion tank 370 can store about 4 to 8 liters of heating water, and when combustion is made while the three-way valve 390 is switched to the hot water position, the heating water circulating in the closed circuit is heated to expand the heating water. The tank 370 has a function of accumulating thermal energy that can prevent freezing of the distal end of the exhaust container 360.
배관 내부를 흐르는 난방수의 온도는 난방수온도측정센서(도면에 미도시)에 의해 검지되고, 제어부(101)에서는 측정된 난방수 온도가 미리 설정된 온도에 도달하는지 여부를 판단하고, 미리 설정된 온도에 도달한 경우 배기통(360) 말단부의 결빙을 방지할 수 있는 온도라고 판단하여 소화행정을 실시한다.The temperature of the heating water flowing inside the pipe is detected by a heating water temperature measuring sensor (not shown in the drawing), and the controller 101 determines whether the measured heating water temperature reaches a preset temperature, and sets the preset temperature. When it reaches to determine the temperature that can prevent the freezing of the end of the exhaust pipe 360, the fire extinguishing stroke is performed.
여기서 상기 버너(330)의 소화행정을 실시하기 위해 미리 설정되는 난방수 온도는, 삼방밸브(390)가 온수위치로 전환된 상태에서 팽창탱크(370)를 포함하여 이루어지는 난방수 순환 폐회로에서 상승시킬 수 있는 최대온도인 것이 바람직하다. 통상 보일러 내부 난방 배관수의 온도는 80~85도 정도까지 상승시키는 것이 가능하나, 난방수가 순환되는 유로 구조가 특정되면 실험에 의해 최대온도가 결정할 수 있다.Here, the heating water temperature which is set in advance to perform the fire extinguishing stroke of the burner 330 may be raised in the heating water circulation closed circuit including the expansion tank 370 while the three-way valve 390 is switched to the hot water position. It is preferred that it is the maximum temperature that can be achieved. In general, the temperature of the piping water inside the boiler can be raised to about 80 to 85 degrees, but the maximum temperature can be determined by experiments when the flow path structure for circulating the heating water is specified.
소화행정이 이루어지면, 순환펌프(350) 및 송풍기(320)가 작동되고, 송풍기(320)에 의해 이송된 공기는 주열교환기(340)에서 상기 과정에 의해 가열된 난방수와 열교환을 함으로써 더운 공기로 전환되고, 이 공기는 배기통(360)를 따라 외부로 배출될 때 배기통(360) 말단부의 수증기 또는 응결된 물방울과 접촉됨으로써 결빙을 방지하게 된다.When the extinguishing stroke is made, the circulation pump 350 and the blower 320 are operated, and the air transferred by the blower 320 exchanges heat with the heating water heated by the above process in the main heat exchanger 340 to heat the hot air. When the air is discharged to the outside along the exhaust cylinder 360, the air is contacted with water vapor or condensed water droplets at the distal end of the exhaust cylinder 360 to prevent freezing.
