멀티보일러는 가정용의 소형 보일러를 다수개 병렬로 연결하여 대형 보일러의 용량을 갖도록 한 것으로써, 가정용 보일러를 기반으로 구성한 것으로써 대형 보일러와 달리 별도의 보일러 관리 인력이 필요하지 않고 누구나 관리가 가능한 이점이 있다. 또한, 가정용 소형 보일러를 사용함으로써 협소한 공간에 설치가 가능하고 유지보수 및 관리가 간편한 이점이 있다. 또한, 멀티보일러는 적은 열량부터 일부의 보일러가 가동되면서 필요한 열량만큼 보일러가 가동됨으로써 대형 보일러보다 유지비가 적게 드는 장점을 갖고 있다.Multi boilers have a large boiler capacity by connecting a number of small boilers in parallel in a home, and built on the basis of a domestic boiler, unlike large boilers, no boiler management personnel are required and everyone can manage. There is this. In addition, the use of a small boiler for home can be installed in a small space, there is an advantage that is easy to maintain and manage. In addition, the multi-boiler has the advantage of lower maintenance costs than large boilers by operating the boiler by the required amount of heat while a portion of the boiler operating from a small amount of heat.
이러한 멀티보일러에서 온수를 공급하기 위한 온수제어시스템을 도 1에 도시하였다.1 illustrates a hot water control system for supplying hot water in such a multiboiler.
도 1은 종래의 멀티보일러의 온수제어장치를 나타낸 블록구성도이다.1 is a block diagram showing a hot water control device of a conventional multi-boiler.
여기에 도시된 바와 같이 된 바와 같이 멀티보일러(10)의 개별적인 제 1내지제 n보일러(10-1∼10-n)는 직수입구(2)와 온수출구(4)가 각각 공통으로 연결되어 있고 온수출구(4)에 온수탱크(20)가 구비되어 있다. 그리고 온수탱크(20)에는 온도센서(30)가 구비되어 온수탱크(20)에 온수의 온도를 측정하게 된다.As shown here, each of the first to n-th boilers 10-1 to 10-n of the multi-boiler 10 has a direct inlet 2 and a hot water outlet 4 in common. The hot water tank 20 is provided at the hot water outlet 4. And the hot water tank 20 is provided with a temperature sensor 30 to measure the temperature of the hot water in the hot water tank (20).
그리고 멀티보일러(10)의 온수제어부(40)에 온도센서(30)의 출력값을 입력받아 설정된 온수온도에 따라 멀티보일러(10)의 제 1내지 제 n보일러(10-1∼10-n)들을 선택적으로 미리 작동시켜 온수탱크(20)의 온수를 설정한 온도로 유지하여 항상 일정한 온도가 되도록 온수탱크(20)에 다량의 온수를 보관하게 된다.The first to n-th boilers 10-1 to 10-n of the multi-boiler 10 are received by receiving the output value of the temperature sensor 30 to the hot water control unit 40 of the multi-boiler 10 according to the set hot water temperature. By selectively operating in advance to maintain the hot water in the hot water tank 20 at the set temperature to keep a large amount of hot water in the hot water tank 20 to always be a constant temperature.
이와 같이 온수탱크(20)를 이용한 온수제어장치는 온수탱크(20)에 온수가 보관되어 있기 때문에 온수량이 풍부하다는 장점은 있으나 온수탱크(20)의 설치를 위한 공간확보를 위한 문제점과, 현재 사용하지 않음에도 불구하고 온수탱크(20)에 일정한 량의 온수를 일정한 온도로 보관하기 위해 멀티보일러(10)를 작동시켜야 하기 때문에 연료소모가 많다는 문제점이 있다.As described above, the hot water control device using the hot water tank 20 has the advantage that the amount of hot water is abundant because hot water is stored in the hot water tank 20, and there is a problem for securing the space for the installation of the hot water tank 20, and Although not used, there is a problem in that fuel consumption is high because the multiboiler 10 must be operated in order to store a constant amount of hot water at a constant temperature in the hot water tank 20.

도 2는 본 발명에 의한 멀티보일러의 온수제어장치를 나타낸 블록구성도이다.2 is a block diagram showing a hot water control device of a multi-boiler according to the present invention.
여기에 도시된 바와 같이 사용하고자 하는 온수온도를 설정하는 온수온도 설정부(50)와, 멀티보일러(10)를 이루고 있는 제 1내지 제 n보일러(10-1∼10-n)의 개별보일러의 직수입구(2)에 각각 설치된 제 1내지 제 n전자밸브(70-1∼70-n)와, 멀티보일러(10)의 온수출구(4)에 설치된 유량센서(60)와, 온수온도 설정부(50)의 값과 유량센서(60)의 값에 따라 제 1내지 제 n전자밸브(70-1∼70-n)와 멀티보일러(10)의 작동을 제어하는 온수제어부(40)로 이루어진다.As shown here, the hot water temperature setting unit 50 for setting the hot water temperature to be used and the individual boilers of the first to n-th boilers 10-1 to 10-n constituting the multi-boiler 10 are provided. First to nth solenoid valves 70-1 to 70-n respectively provided at the direct inlet 2, a flow sensor 60 provided at the hot water outlet 4 of the multiboiler 10, and a hot water temperature setting unit. The hot water control unit 40 controls the operation of the first to n-th solenoid valves 70-1 to 70-n and the multi-boiler 10 according to the value of 50 and the value of the flow rate sensor 60.
위와 같이 이루어진 본 발명에 의한 작동을 도 3에 도시된 멀티보일러의 온수제어장치의 작동방법을 설명하기 위한 흐름도를 참조하여 설명하면 다음과 같다.The operation according to the present invention made as described above will be described with reference to a flowchart for explaining an operation method of the hot water control device of the multi-boiler shown in FIG.
먼저, 온수를 사용하는 유량을 유량센서(60)에 의해 감지하게 된다(S10).First, the flow rate using the hot water is detected by the flow sensor 60 (S10).
이와 같이 유량을 감지하여 유량이 감지되지 않을 경우에는 사용하지 않는 것으로써 제 1내지 제 n전자밸브(70-1∼70n) 중 열려있는 전자밸브(70)가 있을 경우에는 모두 닫아 멀티보일러(10)의 작동을 중지시키고 계속해서 유량상태를 감지하는 단계(S10)로 리턴된다(S20).As such, when the flow rate is sensed and the flow rate is not sensed, the flow rate is not used. If there is an open solenoid valve 70 among the first to nth solenoid valves 70-1 to 70n, all of them are closed and the multi boiler 10 is closed. ) Is stopped and the flow returns to step S10 of detecting the flow state (S20).
그러나, 유량이 감지될 경우에는 감지된 유량과 온수온도 설정부(50)에서 설정된 온도에 따라 필요열량을 계산한다(S30).However, when the flow rate is detected, the required heat amount is calculated according to the detected flow rate and the temperature set by the hot water temperature setting unit 50 (S30).
이렇게 계산된 필요열량 및 제 1내지 n보일러(10-1∼10-n)의 개별보일러들의 작동우선순위에 따라 개별보일러를 선택한다(S40). 따라서, 이렇게 선택된 개별보일러의 전자밸브(70)를 개방하여 직수를 공급한다(S50). 그러면 온수흐름스위치(미도시)가 작동하여 보일러가 가동하여 온수를 공급하게 된다.The individual boilers are selected according to the required calories and the operation priority of the individual boilers of the first to n boilers 10-1 to 10-n (S40). Thus, the solenoid valve 70 of the selected individual boiler is opened to supply water directly (S50). Then, the hot water flow switch (not shown) is operated to supply the hot water by operating the boiler.
이때 필요열량이 클 경우에는 동시에 두 개 이상의 개별보일러가 작동하게 된다.At this time, when the required heat is large, two or more individual boilers are operated at the same time.
이와 같이 선택된 개별보일러들이 작동된 경과시간을 비교하게 된다(S60).Thus, the selected individual boilers are compared with the elapsed time of operation (S60).
즉, 제 1내지 제 n보일러(10-1∼10-n)들이 병렬로 연결되어 이루어진 멀티보일러(10)에서 어느 하나의 개별보일러만 연속적으로 작동될 경우 보일러의 수명을 단축시키기 때문에 보일러의 수명을 연장하기 위해 일정시간만 보일러를 가동하고 그 외 보일러를 순차적으로 가동시켜 보일러의 총 가동시간을 일정하게 유지하도록 한다.That is, when only one boiler is continuously operated in the multi-boiler 10 in which the first to n-th boilers 10-1 to 10-n are connected in parallel, the lifetime of the boiler is shortened. In order to extend the boiler, the boiler is operated only for a certain time and the other boilers are operated sequentially to keep the total operating time of the boiler constant.
따라서, 선택된 개별보일러가 일정시간 경과되지 않았을 경우에는 계속해서 작동되기 유량과 설정온도에 따라 온수를 공급하기 위해 유량을 감지하는 단계(S10)로 리턴된다(S60).Therefore, when the selected individual boiler has not elapsed for a predetermined time, the flow returns to the step S10 of detecting the flow rate to supply hot water according to the flow rate and the set temperature to be continuously operated (S60).
그러나, 일정시간 이상 선택된 개별보일러가 작동되었을 경우에는 선택되어 작동중인 개별보일러의 전자밸브를 닫아 보일러의 작동을 정지시키고(S70), 개별보일러의 작동 우선순위를 후순위로 변경하여 다음에 선택할 때 후순위로 선택되도록 한다(S80).However, when the selected individual boiler is operated for a certain time, the boiler is stopped by closing the solenoid valve of the selected and operating individual boiler (S70). To be selected (S80).
이렇게 우선순위를 변경한 후 유량감지하는 단계(S10)로 리턴되어 계속해서 온수를 사용하기 위해 유량이 감지될 경우에는 설정된 온수온도와 유량에 따라 열량이 계산되고(S30) 열량 및 개별보일러의 우선순위에 따라 개별보일러를 선택하게 된다(S40).After changing the priority and returning to the flow rate sensing step (S10), if the flow rate is detected to continue using the hot water, the heat quantity is calculated according to the set hot water temperature and the flow rate (S30), and the heat quantity and the priority of the individual boiler. The individual boiler is selected according to the ranking (S40).
그런데 위에서 방금 일정시간 이상 작동된 개별보일러들은 우선순위가 후순위로 변경되어 있기 때문에 이전에 작동되지 않은 개별보일러가 제 1내지 제 n보일러(10-1∼10-n) 중에서 선택되게 됨으로써 순차적으로 개별보일러들이 돌아가면서 고르게 작동되어 특정한 개별보일러만 연속 가동되지 않도록 작동된다.However, since the individual boilers that have just been operated for a predetermined time above have their priorities changed to subordinated priorities, the individual boilers which have not been previously operated are selected from the first to n-th boilers 10-1 to 10-n, thereby sequentially. The boilers operate evenly over time so that only certain individual boilers do not run continuously.
위와 같은 작동을 온수를 사용하는 동안 계속 반복 작동된다.The above operation continues to be repeated while using hot water.
상기한 바와 같이 본 발명은 멀티보일러에서 온수를 제어할 때 온수탱크의 온수온도를 측정하여 제어하지 않고 멀티보일러의 온수출구에 유량센서를 설치하고 각 보일러의 직수입구에 전자밸브를 설치하여 유량에 필요한 열량만큼 보일러를 선택적으로 가동시켜 연료비의 절감 및 설치 및 관리가 용이한 이점이 있다.As described above, the present invention does not measure and control the hot water temperature of the hot water tank when controlling hot water in the multi-boiler, and installs a flow sensor at the hot water outlet of the multi-boiler and installs a solenoid valve at the direct inlet of each boiler to control the flow rate. By selectively operating the boiler by the required amount of heat, there is an advantage of reducing fuel costs and easy to install and manage.
또한, 멀티보일러를 이루고 있는 개별보일러를 순차적으로 일정시간 동안 돌아가면서 작동되기 때문에 개별보일러의 수명을 연장시킬 수 있는 이점이 있다.In addition, since the individual boilers constituting the multi-boiler are sequentially operated for a predetermined time, there is an advantage that can extend the life of the individual boiler.
