본 고안은 적산(積算) 열량계의 온도차 측정장치에 관한 것이다.The present invention relates to a temperature difference measuring device of an integrated calorimeter.

종래, 소비열량을 측정하는 수단으로, 서열부하측에 열매체를 공급하는 이송관과 열부하측에서 열매체를 되돌리는 반송관 중도부에 열매체의 온도를 검출하는 검출부를 형설, 이들 검출부에 있어서 검출한 온도의 차를 구함에 따라서 소비열량을 측정하는 방법이 있었다.Conventionally, as a means for measuring the amount of heat consumed, a transfer section for supplying the heat medium to the sequence load side and a detection unit for detecting the temperature of the heat medium in the transfer tube middle part returning the heat medium from the heat load side are formed. There was a method of measuring calorie consumption as a result of finding the difference.

그러나, 종래의 이와같은 온도 검출부는 이송관 및 반송관의 중도부에 취부공을 천설하고 이 취부공에서 온도검출소자를 관내에 삽입하여 열매체 즉, 온수온도를 직접 측정하도록 되어 있다.However, such a conventional temperature detection part installs a mounting hole in the middle part of the conveying pipe and the conveying pipe, and inserts a temperature detecting element into the pipe to directly measure the heat medium, that is, the hot water temperature.

따라서 열매체의 온도를 정확하게 검출할 수 있기는 하나, 그 반면에 방수구조로 하기 위하여 구조적으로 복잡하며, 시공작업 및 보수점검이 곤난하여 생산원가가 높은 요인이 될 뿐 아니라, 관내에 온도 검출소자를 돌출시키면, 유통저항이 커져 압력 손실이 발생한다는 결점이 있었다.Therefore, it is possible to accurately detect the temperature of the heat medium, but on the other hand, it is structurally complicated to have a waterproof structure, and the production cost is high due to difficult construction work and maintenance inspection, and the temperature detection element in the pipe If it protrudes, there exists a fault that a flow loss becomes large and a pressure loss arises.

본 고안은 상기 사정을 착안하여 이루어진 것으로 이의 목적으로 하는 열매체의 이송관반 과송관의 중도부에 온도검출용관을 접촉하고 이 온도 검출관의 외표면에 시이트상의 온도 검출소자를 부착한 온도 검출부를 일체로 구성하여 구조적으로 간단하게 함과 동시에 취부, 보수, 점검 등이 극히 용이하게 실시할 수 있게함으로서 저렴가의 적산열량계의 온도차 측정장치를 제공함에 있는 바, 이를 도면 및 실시예에 따라 상세히 설명하면 다음과 같다.The present invention has been made in view of the above circumstances, and the temperature detecting part which has contacted the temperature detecting tube in the middle part of the conveying tube transfer tube of the heat medium for the purpose and attached the sheet temperature detecting element to the outer surface of the temperature detecting tube is integrated. The present invention provides a device for measuring the temperature difference of an inexpensive integrated calorimeter by simplifying the structure and making the installation, maintenance, and inspection extremely easy. The following description will be made in detail with reference to the accompanying drawings and examples. Same as

제1도에서와 같이 이송관(1) 및 반송관(2)의 일단측은 열매체 에 ： 온수공급원(23)에 접속되게 하는 한편 타단측은 난방, 급탕장치 등의 열부하측(24)에 접속되게 열매체 순환로를 구성하며, 이송관(1) 및 반송관(2)중도부에는 온도검출부(3)(4)를 형성한다.As shown in FIG. 1, one end of the transfer pipe 1 and the transfer pipe 2 is connected to the heat medium: the hot water supply source 23, while the other end is connected to the heat load side 24 such as a heating or hot water supply device. A circulation path is formed, and temperature detectors 3 and 4 are formed in the intermediate portion of the transfer pipe 1 and the transfer pipe 2.

이들 온도검출부(3)(4)는 동일 구조임으로 일측만에 대하여 설명하면, (5)는 열전도성이 우수한 동 또는 강재료로 된 온도 검출용관인 바, 이 온도검출용관(5)의 양단부에는 숫나사(6)를 갖는 접속환(7)(7)이 고착되며, 이들 접속환(7)(7)의 숫나사(6)(6)는 이송관(1)의 암나사(8)(8)에 나착되여 있다.Since only one side of these temperature detectors 3 and 4 has the same structure, (5) is a temperature detection tube made of copper or steel having excellent thermal conductivity, so that both ends of the temperature detection tube 5 Connection rings (7) (7) having male threads (6) are fixed, and male threads (6) (6) of these connection rings (7) (7) are connected to the female threads (8) (8) of the feed pipe (1). Are obsessed.

따라서 온도검출용관(5)의 내주면은 이송관(1)을 유통하는 온수등의 열매체(a)와 접속토록 되어 있으며, 이 온도 검출용관(5)의 외표면의 일부에는 예컨대, 시이트상의 열전대(熱電對) 또는 시이트상의 측온저항체등의 온도 검출소자(9)가 부착되어 있다. 이의 온도검출소자(9)의 외주에는 온도검출용관(5)을 둘러싼 단열재(10)가 형성되어 있고, 이의 외측에는 카버(11)로 피복되어 있으며, 온도검출용관(5)에 대하여 일체로 구성되여 있다.Therefore, the inner circumferential surface of the temperature detection tube 5 is connected to a heating medium a such as hot water circulating through the transfer tube 1, and a part of the outer surface of the temperature detection tube 5 is, for example, a sheet-like thermocouple ( A temperature detecting element 9, such as a thermocouple or sheet-like resistance thermometer, is attached. A heat insulating material 10 surrounding the temperature detecting tube 5 is formed on the outer circumference of the temperature detecting element 9, and the outer side of the temperature detecting element 9 is covered with a cover 11, and is integrally formed with the temperature detecting tube 5. It is.

그리고 온도검출소자(9)는 열매체에서의 열전도에 따라 가열되는 온도 검출용관(5)의 외표면 온도를 검출토록 되여 있으며, 이 때 온도검출소자(9)는 단열재(10)에 의하여 주위온도에 영향을 받지 않는다.The temperature detecting element 9 is configured to detect the outer surface temperature of the temperature detecting tube 5 which is heated according to the heat conduction in the heat medium, and the temperature detecting element 9 is insulated from the ambient temperature by the heat insulator 10. It is not affected.

이와같이 구성된 온도검출부(3)는 반송관(4)에도 똑같이 온도검출부(3)로서 취부되여 있으며 이들 온도검출부(2)(4)는 리드선(12)(12)을 통하여 증폭회로 또는 온도차전압변환회로(13)에 접속되고 다시 그 증폭회로 또는 온도차전압변환회로(13)는 연산회로(14)를 통하여 적산열량계 표시부(15)에 접속되여 있다.The temperature detecting unit 3 configured in this way is also attached to the conveying pipe 4 as the temperature detecting unit 3, and these temperature detecting units 2 and 4 are connected to the amplification circuit or the temperature difference voltage conversion circuit through the lead wires 12 and 12. The amplification circuit or the temperature difference voltage conversion circuit 13 is connected to the integrated calorimeter display section 15 via the calculation circuit 14.

한편, 상기 온도 검출소자(9)로서 열전대를 사용한 경우는 상기 온도차 전압 변환회로(13)는 필요하지 않다.On the other hand, when the thermocouple is used as the temperature detection element 9, the temperature difference voltage conversion circuit 13 is not necessary.

이리하여, 이송관(1)의 화살방향으로 흐르는 열매체(a)는 열부하측(24)에 있어 열교환된 후 반공관(2)의 화살표방향으로 흘러 온수 공급원(23)에 되돌아가게 된다.Thus, the heat medium a flowing in the direction of the arrow of the transfer pipe 1 is heat-exchanged at the heat load side 24 and then flows in the direction of the arrow of the semi-vacant pipe 2 to return to the hot water supply source 23.

이때 이송관(1)을 흐르는 열매체(a)의 온도는 온도검출용관(5)을 통하여 온도검출소자(9)에 의하여 검출되고, 반송관(2)을 흐르는 열매체(a)의 온도는 온도검출용관(5)을 통하여 온도검출소자(9)에 의하여 검출된다.At this time, the temperature of the heat medium (a) flowing through the transfer pipe (1) is detected by the temperature detecting element (9) through the temperature detection tube (5), the temperature of the heat medium (a) flowing through the conveying pipe (2) is detected temperature It is detected by the temperature detecting element 9 through the tube 5.

이와같이 하여 온도검출부(3)(4)에 의하여 각기 이송관(1)과 반송관(2)의 온도를 검출하고 그 온도차는 열부하측(24)에 있어서의 소비된 열량이 된다.In this way, the temperature detection part 3 (4) detects the temperature of the conveyance pipe 1 and the conveyance pipe 2, respectively, and the temperature difference becomes the amount of heat consumed in the heat load side 24. As shown in FIG.

따라서 온도 검출부(3)(4)로부터의 전기신호는 증폭회로 또는 온도차 전압변환회로(13)→연산회로(14)→적산열량계 표시부(51)의 순으로 보내져 열부하측(24)에서 소비된 열량을 적산 표시하게 된다.Therefore, the electric signals from the temperature detectors 3 and 4 are sent in the order of the amplification circuit or the temperature difference voltage conversion circuit 13 → the calculation circuit 14 → the integrated calorimeter display section 51, and the amount of heat consumed by the heat load side 24. Will be displayed as integrated.

또 제2도 및 제3도는 본 고안의 온도차 측정장치의 특성시험상태를 나타낸 것으로, 온도검출용관(5)으로서는 강관을 사용하며, 이 외주면에의 시이트 상온도검출소자(9)로서의 시이트상 열전대(91), (92), (93), (94)를 90°간격으로 장착하고 이 외표면을 그라스울로된 단열재(10)로 피복하고 다시 그 외주면을 알루이늄박으로 된 카버(11)로 피복한다.2 and 3 show the characteristic test state of the temperature difference measuring apparatus of the present invention. As the temperature detecting tube 5, a steel tube is used, and the sheet phase thermocouple as the sheet phase temperature detecting element 9 on the outer circumferential surface thereof. 9 1 ), (9 2 ), (9 3 ), and (9 4 ) are mounted at 90 ° intervals, and the outer surface is covered with a glass wool insulation (10), and the outer peripheral surface is made of aluminum foil (11) )).

또 상기 온도검출용관(5) 내에 반도체센서(16)를 삽입하여 이를 직류전원(17)에 접속함과 동시에, 상기 각 시이트상열전대(91), (92), (93), (94)를 각각 보상기(18) 및 스위치박스(19)를 통하여 디지탈 전압계(20)에 접속한다.In addition, the semiconductor sensor 16 is inserted into the temperature detecting tube 5 and connected to the DC power source 17, and the sheet thermocouples 9 1 , 9 2 , 9 3 , and ( 9 4 ) are connected to the digital voltmeter 20 via a compensator 18 and a switch box 19, respectively.

다시 상기 온도검출용관(5)의 일단측을 입구로 하여 2중관식 유리기준 온도계(21)를 갖는 액체항온조(22)에 접속하고, 타단측을 출구로서 상기 액체항온조(22)에 접속한다.One end of the temperature detection tube 5 is again used as an inlet and connected to a liquid thermostat 22 having a double tube type glass reference thermometer 21, and the other end is connected to the liquid thermostat 22 as an outlet.

이 상태로서 미리 상기 기준온도계(21)를 사용하여 설정한온도의 액체항온조(22) 내의 온수를 상기 온도검출용관(5)의 입구에서 공급하고, 온도검출용관(5) 내를 유통시켜 출구에서 액체항온조(22)에 환류시킨다. 온도검출용관(5)내의 온도는 반도체 센서(16)에 직류전원(17)으로부터 정전류를 공급함으로서, 전압계(20)로 검출된다. 그후, 즉시 스위치박스(19)를 열전대측에 절환시키면 온도검출용관(5) 외주면의 온도는 시이특상 열전대(91), (92), (93), (94)에 의하여 보상기(18)를 통하여 전압계(20)로 검출된다.In this state, hot water in the liquid thermostat tank 22 having the temperature set in advance by using the reference thermometer 21 is supplied from the inlet of the temperature detection tube 5, and the inside of the temperature detection tube 5 is circulated. It is refluxed to the liquid thermostat 22. The temperature in the temperature detection tube 5 is detected by the voltmeter 20 by supplying a constant current from the DC power supply 17 to the semiconductor sensor 16. Thereafter, the switch box 19 is immediately switched to the thermocouple side, and the temperature of the outer circumferential surface of the temperature detecting tube 5 is adjusted by the compensator (9 1 ), (9 2 ), (9 3 ), and (9 4 ). 18 is detected by the voltmeter 20.

제4도는 상기 특성 시험에 있어서의 검출결과를 그래프화한 것으로, 이 그래프에서 알 수 있는 바와 같이 온도검출용관(5)의 중심 즉, 반도체센서(16)의 검출온도를 기준치로 하고 각 시이트상 열전대(91), (92), (93), (94)의 검출온도 등을 비교한 바, 그 비교치는 근소(1℃미만)하며, 전기회로로 보정이 가능하다.FIG. 4 is a graph of the detection results in the characteristic test. As can be seen from this graph, the center of the temperature detection tube 5, that is, the detection temperature of the semiconductor sensor 16 is used as a reference value. When the detection temperatures of the thermocouples 9 1 , 9 2 , 9 3 , and 9 4 were compared, the comparison value was near (less than 1 ° C.) and can be corrected by an electric circuit.

따라서 온도검출용관(5)의 외표면의 온도를 시이트상 열전대 등의 온도 검출소자(9)로 검출한 것만으로 온도검출용관(5)내를 유통하는 액체온도를 정확하게 검출할 수 있음을 확인하였다.Therefore, only by detecting the temperature of the outer surface of the temperature detecting tube 5 with a temperature detecting element 9 such as a sheet-type thermocouple, it was confirmed that the liquid temperature flowing in the temperature detecting tube 5 can be accurately detected. .

이상 설명한 바와 같이 본 고안은 열매체를 유통하는 이송관과 반송관의 중도부에 온도검출관을 접속하고 이 온도검출용관의 외표면에 시이트상의 열전대 또는 측온저항체 등의 온도 검출소자를 부착하여 또 단열재로 피복하여 일체로 구성하였음으로서 온도검출부의 구조의 간소화를 기할 수 있음과 동시에 배관의 설치가 용이한 것이다.As described above, the present invention connects the temperature detecting tube to the middle part of the conveying tube and the conveying tube which distributes the heat medium, and attaches a temperature detecting element such as a thermocouple or a resistance thermometer to the outer surface of the temperature detecting tube and heat insulating material. In this case, the structure of the temperature detector can be simplified and the piping can be easily installed.

따라서 저렴가로 시공이 가능함과 동시에 보수, 점검도 간편 용이하며, 온도검출용관의 외표면 온도를 검출하도록 된 것임으로 열매체의 흐름을 방해하지 않기 때문에 압력손실을 방지한다는 효과도 있는 유용한 고안인 것이다.Therefore, it is possible to construct at low cost and at the same time easy to repair and check, and to detect the temperature of the outer surface of the temperature detection tube, it is a useful design that has the effect of preventing pressure loss because it does not disturb the flow of the heat medium.
