Description

저온 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템{Integrated hot water piping system to block inflow of low temperature heat source supply water}Integrated hot water piping system to block inflow of low temperature heat source supply water

본 발명은 공동주택 또는 건물 등의 지역 및 중앙난방 열원으로부터 공급될 수 있는 저온의 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템에 관한 것이다.The present invention relates to a hot water heating integrated piping system that controls the inflow of low-temperature heat source supply water that can be supplied from a central heating heat source and an area such as an apartment house or building.

아파트 등의 공동주택 또는 건물 및 지하실 등의 개별 가구에 대한 지역난방 또는 중앙난방에서 급탕 난방 공급을 위한 배관시스템은 급탕용 열교환기와 난방용 열교환기를 두고 4-파이프 배관으로 연결하여 급탕과 난방을 하도록 구성 되어 있지만 최근에는 급탕과 난방의 계절 요인이나 예외적 운용에 따른 난방 불능의 문제점과 설치 및 유지보수 그리고 열관리 등의 효율을 좋게 하기 위하여 4-파이프 배관의 급탕과 난방을 통합적으로 운용하는 통합 배관시스템으로 제안되어 있다. 대한민국 등록특허공보 제10-1081599호 및 대한민국 등록특허공보 제10-1425870호에는 하나의 열원으로 급탕과 난방을 통합적으로 운용하는 배관시스템에 관하여 기재되어 있다. 그러나, 기존의 급탕 난방 통합 배관시스템은 기계실 등에서 고장 등의 문제 발생 시 발생 초기에 별도의 조치가 없는 경우 밸브가 전폐되지 않은 상태여서 저온의 난방수(열원공급수)가 통합배관유닛으로 바로 유입되어 열량계가 불필요하게 동작하게 되고 이로 인해 난방손실이 발생되고 난방성능이 저하될 수 있다. 이에 따라, 기존의 급탕 난방 통합 배관시스템은 저온의 열원공급수가 통합배관유닛으로 유입되어 열량계가 불필요하게 동작하는 것을 방지하고 난방 사용 시에는 난방공급라인을 구성하는 난방공급관-각방분배기-난방환수관 등으로 저온의 열원공급수 유입을 제한하여 난방온도 저하 시간을 제어할 수 있는 제안이 필요한 실정이다.The piping system for supplying hot water heating from district heating or central heating to apartments, apartments, or individual furniture such as buildings and basements is composed of hot water and heating by connecting a heat exchanger for hot water and a heat exchanger with a 4-pipe pipe. However, in recent years, it is an integrated piping system that integrates hot water and heating of 4-pipe piping in order to improve the efficiency of installation, maintenance, and heat management, as well as the problem of heating inability due to seasonal factors or exceptional operation of hot water and heating. Is proposed. Korean Registered Patent Publication No. 10-1081599 and Korean Registered Patent Publication No. 10-1425870 describe a piping system that integrates hot water and heating as a single heat source. However, in the case of a problem such as a breakdown in the machine room, the existing hot water heating integrated piping system is in a state where the valve is not completely closed when there is no other measure at the beginning of the occurrence of a problem such as a malfunction in the machine room, so low-temperature heating water (heat source water) flows directly into the integrated piping unit As a result, the calorimeter may operate unnecessarily, resulting in heating loss and deterioration of heating performance. Accordingly, the existing hot water heating integrated piping system prevents the heat source supply water from flowing into the integrated piping unit and causes the calorimeter to operate unnecessarily, and when heating is used, the heating supply pipe constituting the heating supply line-each room distributor-heating return pipe There is a need for a proposal that can control the heating temperature drop time by limiting the inflow of low-temperature heat source supply water.

The hot water heating integrated piping system of FIG. 1 is an example in which hot water and a heating flow path are integrated into an integrated piping unit 100.

기존의 급탕 난방 통합 배관시스템은 난방에서는 열원(A)으로부터 난방수의 공급이 열교환기(104)를 경유하여 On-Off 밸브(103)를 거쳐 분배기(102)를 통해 난방부하측(101)으로 공급되고 차압 밸브(105)가 설치된 환수유로(106)를 통해 열원환수측(107)으로 환수되도록 되어 있다.In the existing hot water heating integrated piping system, in heating, heating water is supplied from the heat source (A) to the heating load side 101 through the On-Off valve 103 via the heat exchanger 104 and through the distributor 102 And the differential pressure valve 105 is to be returned to the heat source return side 107 through a return passage 106 installed.

난방에서는 난방부하측(101)에 공급되는 열원공급수(난방수)가 분배기(102)에 구비되는 미세조절 밸브(108)의 조작을 통해 난방부하측(101)의 각 실(예를 들면 거실/주방/방1,2,3...n 등)로 공급되어 난방을 실시하도록 되어 있다.In heating, the heat source supply water (heating water) supplied to the heating load side 101 is operated by the fine control valve 108 provided in the distributor 102 to each room of the heating load side 101 (for example, living room/kitchen /It is supplied to rooms 1, 2, 3...n, etc.) to conduct heating.

급탕에서는 열원(A)으로부터 공급되는 열원공급수(열원수)가 열교환기(104)를 경유하여 유량조절밸브(113)에 의해 환수 유량이 조절되어 환수되고 외부로부터 공급되는 급수(W1)는 열교환기(104)를 경유하면서 열교환되어 급탕(W2) 온수로 출탕 되도록 되어 있다.In the hot water supply, the heat source supply water (heat source water) supplied from the heat source (A) passes through the heat exchanger 104 and the return flow rate is adjusted by the flow control valve 113 to be returned, and the water supply (W1) supplied from the outside is heat exchanged. It is heat-exchanged while passing through the machine 104 so as to be hot water from the hot water supply (W2).

도 1과 같이 급탕과 난방이 통합배관유닛(100)에 통합된 기존의 급탕 난방 통합 배관시스템에서는 보일러 기계실(110)의 고장이나 작동 에러가 발생되면 열원공급수를 목표온도(대략 약 60~65 ℃)로 올리지 못하여 목표온도에 미달되는 저온의 열원공급수를 공급하게 되는 경우가 발생될 수 있다.In the existing hot water heating integrated piping system in which hot water and heating are integrated into the integrated piping unit 100 as shown in FIG. 1, when a failure or operation error of the boiler machine room 110 occurs, the heat source supply water is set to a target temperature (approximately about 60 to 65). ℃), and supplying low-temperature heat source supply water that does not reach the target temperature may occur.

목표온도(t1_max)에 미달하는 저온의 열원공급수가 난방라인(120)에 공급되면 통합배관유닛(100)에 구성되는 각종 열량계(미도시)들이 불필요하게 작동하게 되고, 이로 인해 목표온도에 미달하는 열원공급수를 사용하고도 정상요금을 정산하도록 하는 등 사용자 피해가 생길 수 있고, 저온의 열원공급수로 인해 난방과 급탕 온수의 생성 성능이 저하될 수 있다.When the low-temperature heat source supply water that does not reach the target temperature (t1_max) is supplied to the heating line 120, various calorimeters (not shown) configured in the integrated piping unit 100 operate unnecessarily. Even if the heat source supply water is used, damage to the user may occur, such as having to settle the normal rate, and the heating and hot water generation performance may be degraded due to the low temperature heat source supply water.

본 발명은 급탕 난방 통합 배관시스템에서 난방 사용 시 난방라인을 따라 저온 열원공급수가 유입되어 나타나는 난방 및 급탕 성능의 문제를 개선할 수 있도록 제시된다.The present invention is presented to improve the heating and hot water performance problems that appear when low temperature heat source supply water is introduced along a heating line when heating is used in a hot water heating integrated piping system.

도 2는 본 발명의 실시예에 따른 저온 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템의 예시이다.2 is an illustration of a hot water heating integrated piping system that controls the inflow of low-temperature heat source supply water according to an embodiment of the present invention.

본 발명의 다른 실시예에 따른 저온 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템(200)은 도 2에 도시된 바와 같이 열원을 열원공급라인(130)을 통해 열원공급수를 공급받아 난방에 필요한 난방수 또는 급탕온수를 출탕하도록 유도하는 통합배관유닛(201)으로 구성될 수 있다.In the hot water heating integrated piping system 200 for controlling the inflow of low-temperature heat source supply water according to another embodiment of the present invention, as shown in FIG. 2, the heat source is supplied with the heat source supply water through the heat source supply line 130 for heating. It may be configured with an integrated piping unit 201 that induces the required heating water or hot water to be tapped.

그리고, 통합배관유닛(201)으로 공급되는 열원공급수의 현재 온도를 검출하여 열원공급수의 현재온도가 목표온도(t1_max)에 미달하는 경우 열원공급라인(130)의 유로를 닫는 저온 열원공급수 제어부(202)를 포함하여 구성될 수 있다.In addition, when the current temperature of the heat source supply water supplied to the integrated piping unit 201 is detected and the current temperature of the heat source supply water falls below the target temperature (t1_max), the low temperature heat source supply water closing the flow path of the heat source supply line 130 It may be configured to include the control unit 202.

미설명 부호 T1은 공급 열원의 온도, T2는 급탕환수의 온도, T3는 급수(W1)의 온도, T4는 급탕온수(W2)의 출탕 온도, T5는 난방라인을 경유하는 난방수의 환수온도를 각각 검출할 수 있는 써미스터 등을 포함하는 '온도검출소자'일 수 있다.Unexplained code T1 is the temperature of the supply heat source, T2 is the temperature of the hot water return, T3 is the temperature of the water supply (W1), T4 is the hot water supply temperature (W2), and T5 is the return temperature of the heating water via the heating line. It may be a'temperature detection device' including a thermistor that can detect each.

또한, 저온 열원공급수 제어부(202)는, 도 2에 도시된 바와 같이, 통합배관유닛(201)의 입구측인 열원공급라인(130)에 구비될 수 있다.In addition, the low-temperature heat source supply water control unit 202 may be provided in the heat source supply line 130, which is the inlet side of the integrated piping unit 201, as shown in FIG. 2.

이렇게 통합배관유닛(201)의 입구측인 열원공급라인(130)에 구비되는 저온 열원공급수 제어부(202)는 열원공급수의 현재온도를 검출할 수 있으므로 저온의 열원공급수인 경우 통합배관유닛(201)으로 유동되는 열원공급수의 유입을 차단할 수 있다.In this way, the low temperature heat source supply water control unit 202 provided in the heat source supply line 130 at the inlet side of the integrated piping unit 201 can detect the current temperature of the heat source supply water. It is possible to block the inflow of the heat source supply water flowing to (201).

또한, 저온 열원공급수 제어부(202)는, 통합배관유닛(201)으로 유입되는 열원공급수의 온도를 검출하기 위해 열원공급라인(130)에 설치된 온도검출소자(T1), 온도검출소자(T1)로부터 검출되는 열원공급수의 목표온도(t1_max)가 제어부(미도시)에 기 설정된 목표온도에 미달하는 경우 열원공급라인(130)의 유로를 닫기 위해 열원공급라인(130)에 설치된 밸브(204)를 포함하여 구성될 수 있다.In addition, the low-temperature heat source supply water control unit 202 includes a temperature detection element T1 and a temperature detection element T1 installed in the heat source supply line 130 to detect the temperature of the heat source supply water flowing into the integrated piping unit 201. The valve 204 installed in the heat source supply line 130 to close the flow path of the heat source supply line 130 when the target temperature (t1_max) of the heat source supply water detected from the control unit (not shown) falls below the target temperature preset in the control unit (not shown). ) Can be included.

예를 들어, 온도검출소자(T1)를 통해 검출되는 열원공급수의 현재온도가 50℃이고, 밸브(204)를 전기적으로 제어하는 제어부에 설정된 목표온도(t1_max)가 55℃로 설정되어 있는 경우, 이는 현재 열원공급수의 현재온도가 목표온도 기준값을 충족시키지 못한 것으로 판단하여 열원공급수의 공급이 차단될 수 있고, 반대로 열원공급수의 현재온도가 목표온도(t1_max)인 55℃ 이상인 경우 밸브(204)를 개방하여 열원공급수가 통합배관유닛(201)으로 공급되도록 제어될 수 있다.For example, when the current temperature of the heat source supply water detected through the temperature detection element T1 is 50°C, and the target temperature t1_max set in the control unit electrically controlling the valve 204 is set to 55°C , This is because it is determined that the current temperature of the current heat source supply water does not meet the target temperature reference value, and the supply of the heat source supply water may be blocked. Conversely, when the current temperature of the heat source supply water is above the target temperature (t1_max) of 55°C, the valve By opening 204, the heat source supply water can be controlled to be supplied to the integrated piping unit 201.

여기서, 열원공급수의 목표온도(t1_max)는 기계실(110) 등의 보일러 고장이나 작동 에러가 없는 정상상태에서 얻을 수 있는 열원공급수의 온도일 수 있다.Here, the target temperature (t1_max) of the heat source supply water may be a temperature of the heat source supply water obtained in a normal state in which there is no malfunction or operation error of a boiler such as the machine room 110.

도 2에 도시된 바와 같이 통합배관유닛(201)의 입구측인 열원공급라인(130)을 따라 구성되는 저온 열원공급수 제어부(202)는 목표온도에 미달하는 저온의 열원공급수가 통합배관유닛(201)으로 유입되어 열량계가 불필요하게 동작하는 현상을 효과적으로 제어할 수 있다.As shown in Figure 2, the low-temperature heat source supply water control unit 202 configured along the heat source supply line 130 at the inlet side of the integrated piping unit 201 is the integrated piping unit ( 201), it is possible to effectively control the phenomenon that the calorimeter operates unnecessarily.

또한, 난방 사용 시 난방라인(120)을 따라 저온의 열원공급수가 난방수로 유입되어 나타나는 난방성능 저하의 문제를 제어할 수 있다. 마찬가지로 급탕온도에 미달되는 출탕온수의 온도 저하 문제를 제어할 수 있다.In addition, it is possible to control the problem of deterioration of heating performance that occurs when the low-temperature heat source supply water flows into the heating water along the heating line 120 when using heating. Likewise, it is possible to control the problem of the temperature drop of hot water that falls below the hot water temperature.

도 3은 본 발명의 다른 실시예에 따른 저온 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템의 예시이다.3 is an example of a hot water heating integrated piping system that controls the inflow of low-temperature heat source supply water according to another embodiment of the present invention.

본 발명의 다른 실시예에 따른 저온 열원공급수 유입을 제어하는 급탕 난방 통합 배관시스템(200)은 도 3에 도시된 바와 같이 열원을 열원공급라인(130)을 통해 열원공급수를 공급받아 난방에 필요한 난방수 또는 급탕온수를 출탕하도록 유도하는 통합배관유닛(201)으로 구성될 수 있다.In the hot water heating integrated piping system 200 for controlling the inflow of low-temperature heat source supply water according to another embodiment of the present invention, as shown in FIG. 3, the heat source is supplied with the heat source supply water through the heat source supply line 130 for heating. It may be configured with an integrated piping unit 201 that induces the required heating water or hot water to be tapped.

그리고, 통합배관유닛(201)의 열교환기(104)를 경유하여 난방라인(120)을 통해 난방부하측(101)에 난방수로 공급되는 열원공급수의 현재온도가 목표온도(t1_max)에 미달하는 경우 난방라인(120)의 유로를 닫는 저온 열원공급수 제어부(203)를 포함하여 구성될 수 있다.And, the current temperature of the heat source supply water supplied as heating water to the heating load side 101 through the heating line 120 via the heat exchanger 104 of the integrated piping unit 201 is less than the target temperature (t1_max). In this case, it may be configured to include a low-temperature heat source supply water control unit 203 that closes the flow path of the heating line 120.

또한, 저온 열원공급수 제어부(203)는, 통합배관유닛(201)의 열교환기(104)를 경유하는 열원공급수를 난방부하측(101)에 난방수로 공급하는 난방라인(120)의 난방공급관(121)에 구비하여 구성될 수 있다.In addition, the low-temperature heat source supply water control unit 203 is a heating supply pipe of the heating line 120 that supplies heat source supply water through the heat exchanger 104 of the integrated piping unit 201 to the heating load side 101 as heating water. It may be provided and configured in 121.

이렇게 통합배관유닛(201)의 난방라인(120)의 난방공급관(121)에 구비되는 저온 열원공급수 제어부(202)는 난방수로 난방부하측(101)에 공급되는 열원공급수의 현재온도에 따라 난방공급관(121)의 유로를 제어할 수 있으므로 저온의 열원공급수인 경우 난방부하측(101)으로 유동되는 열원공급수의 유동을 차단할 수 있다.In this way, the low-temperature heat source supply water control unit 202 provided in the heating supply pipe 121 of the heating line 120 of the integrated piping unit 201 depends on the current temperature of the heat source supply water supplied to the heating load side 101 as the heating water. Since the flow path of the heating supply pipe 121 can be controlled, in the case of low temperature heat source supply water, the flow of the heat source supply water flowing to the heating load side 101 can be blocked.

또한, 저온 열원공급수 제어부(203)는, 상기 난방라인(120)의 난방공급관(121)에 설치된 바이메탈 밸브(205)를 포함하여 구성될 수 있다.In addition, the low-temperature heat source supply water control unit 203 may be configured to include a bimetallic valve 205 installed in the heating supply pipe 121 of the heating line 120.

바이메탈 밸브(205)는, 저온 바이메탈 밸브로서, 열원공급수의 현재온도가 목표온도(t1_max)에 도달하는 경우 자동 복귀하여 난방공급관(121)를 따라 난방수로 자동 유입되도록 구성될 수 있다.The bimetallic valve 205 is a low-temperature bimetallic valve, and may be configured to automatically return to the heating water along the heating supply pipe 121 when the current temperature of the heat source supply water reaches the target temperature t1_max.

도 3에 도시된 바와 같이 저온 열원공급수 제어부(203)는 예를 들어, 열원공급수의 현재온도가 50℃이고, 바이메탈 밸브(205)가 열리는 목표온도(t1_max)가 55℃로 되어 있는 경우, 이는 현재 열원공급수의 현재온도가 목표온도 기준값을 충족시키지 못한 것으로 바이메탈 밸브(205)가 닫혀져 난방공급관(121)을 통한 열원공급수의 공급이 차단될 수 있고, 반대로 열원공급수의 현재온도가 목표온도(t1_max) 55℃ 이상인 경우 바이메탈 밸브(205)가 개방되어 열원공급수가 난방라인(120)을 따라 난방부하측(101)으로 공급되도록 제어될 수 있다.As shown in FIG. 3, the low-temperature heat source supply water control unit 203 is, for example, when the current temperature of the heat source supply water is 50°C and the target temperature t1_max at which the bimetallic valve 205 is opened is 55°C. , This is because the current temperature of the current heat source supply water does not meet the target temperature reference value, and the bimetal valve 205 is closed to block the supply of the heat source supply water through the heating supply pipe 121. Conversely, the current temperature of the heat source supply water When is equal to or higher than the target temperature t1_max of 55°C, the bimetallic valve 205 is opened to control the heat source supply water to be supplied to the heating load side 101 along the heating line 120.

여기서, 바이메탈 밸브(205)가 온도에 따라 여닫히는 열원공급수의 목표온도(t1_max)는 기계실(110) 등의 보일러 고장이나 작동 에러가 없는 정상상태에서 얻을 수 있는 온도일 수 있다.Here, the target temperature (t1_max) of the heat source supply water at which the bimetallic valve 205 opens and closes according to the temperature may be a temperature obtained in a normal state in which there is no malfunction or operation error of a boiler such as the machine room 110.

도 3에 도시된 바와 같이 통합배관유닛(201)의 열교환기(104)를 경유하여 공급되는 열원공급수를 난방수로 공급하는 난방라인(120)의 난방공급관(121)에 설치되는 저온 열원공급수 제어부(202)는 목표온도에 미달하는 저온의 열원공급수가 통합배관유닛(201)의 난방수로 공급되어 열량계가 불필요하게 동작하는 현상을 효과적으로 제어할 수 있다.As shown in Figure 3, the low-temperature heat source supply installed in the heating supply pipe 121 of the heating line 120 that supplies the heat source supply water supplied via the heat exchanger 104 of the integrated piping unit 201 as heating water The water control unit 202 can effectively control a phenomenon in which the heat source supply water of a low temperature that is less than the target temperature is supplied to the heating water of the integrated piping unit 201 so that the calorimeter operates unnecessarily.

또한, 난방 사용 시 난방라인(120)을 따라 저온의 열원공급수가 난방수로 유입되어 나타나는 난방성능 저하의 문제를 제어할 수 있다.In addition, it is possible to control the problem of deterioration of heating performance that occurs when the low-temperature heat source supply water flows into the heating water along the heating line 120 when using heating.

이때 설정된 급탕온도에 미달되는 출탕온수로 인해 소비자가 급탕 사용시 열원공급수의 저온상태임을 인지할 수 있으며, 수전등을 통해 온도조절이 쉬운 출탕온수 조절에 비하여, 상대적으로 인지 및 조절하기 어려운 저온의 열원공급수로 인한 난방성능 저하만 선택적으로 방지할 수 있다.At this time, due to the hot water that does not reach the set hot water temperature, the consumer can recognize that the heat source supply water is in a low temperature state when using hot water, and compared to the hot water control, which is easy to control the temperature through a faucet, it is relatively difficult to recognize and control. Only the decrease in heating performance due to the heat source supply water can be selectively prevented.

또한, 도 2 및 도 3에 도시된 바와 같이 저온 열원공급수 제어부(202)(203)는, 열원공급수의 현재온도가 목표온도(t1_max)에 미달하는 경우 이를 외부 신호로 알려주는 알림장치(210)를 포함하여 구성될 수 있다.In addition, as shown in Figs. 2 and 3, the low temperature heat source supply water control unit 202, 203, when the current temperature of the heat source supply water is less than the target temperature (t1_max), a notification device that informs this by an external signal ( 210) may be included.

알림장치(210)는 열원공급수의 온도가 정상온도인 목표온도(t1_max) 범위를 벗어나 목표온도에 미달하는 저온 상태에서 이상이 있을 때 이를 사용자에게 전달한다. 사용자는 알림장치(210)를 통해 송출되는 경보음, 음성, 점멸신호 등을 전달받아 이를 기계실의 고장이나 시스템 에러를 판단하여 즉각 대응 조치로 기계실 등의 신속한 점검과 복구가 가능하다.When there is an abnormality in the low temperature state where the temperature of the heat source supply water falls out of the target temperature t1_max, which is the normal temperature, and falls below the target temperature, the notification device 210 transmits this to the user. The user receives the alarm sound, voice, and flashing signal transmitted through the notification device 210 and determines a malfunction or system error in the machine room, and promptly checks and restores the machine room, etc. as an immediate response.
