Description

열전소자를 이용한 자가발전식 열량계 및 열량 측정 방법Self-powered calorimeter and calorimetry method using thermoelectric element
본 발명은 배관을 통해 공급되는 냉방 혹은 난방용 에너지의 양을 측정하는 열량계에 관한 것이다. The present invention relates to a calorimeter for measuring the amount of cooling or heating energy supplied through the pipe.
대규모 열 생산 시설을 이용하여 생산한 열수를 특정 지역에 있는 건물 등으로 공급하여 난방용으로 사용할 수 있게 하는 것이 지역난방 시스템이다. 이러한 지역난방 시스템을 이용하는 건물은 자신이 사용한 열량에 따라 그 비용을 지불하게 되는데, 이를 위해 개별 건물에 열량계가 설치된다.District heating system is to supply hot water produced by using large scale heat production facilities to buildings in a specific area and use it for heating. Buildings using these district heating systems pay for their own calories, which are installed in individual buildings.
열량계는 통상적으로 전자부품을 이용하여 열량을 계산하게 되는데, 이러한 전자부품에 전기 에너지를 공급하기 위해 열량계는 배터리와 같은 에너지 공급 장치를 별도로 구비하게 된다.Calorimeters typically calculate calories using electronic components, and in order to supply electrical energy to these electronic components, the calorimeter includes a separate energy supply device such as a battery.
그런데, 이러한 배터리와 같은 에너지 공급 장치를 이용하여 열량계의 전자부품에 전기 에너지를 공급하는 방식은 몇 가지 문제를 안고 있다. 그 첫번째는 인건비의 발생이다. 배터리에 저장되어 있는 전기 에너지가 모두 소모되는 경우, 관리자가 일일이 소모된 배터리를 교체해야 하기 때문에 이러한 업무 처리를 위한 인건비가 별도로 발생하게 된다. 두번째 문제는 지역난방 시스템에 적용되는 열량계는 고온에 노출될 가능성이 높은데, 배터리는 통상적으로 고온 특성이 좋지 않아 수명이 짧아지고 이로 인해 잦은 배터리 교체가 요구되며 심한 경우 배터리의 잔류 에너지가 없어 열량을 측정하지 못하는 문제가 발생할 수도 있다.However, a method of supplying electrical energy to electronic components of a calorimeter using an energy supply device such as a battery has some problems. The first is the occurrence of labor costs. When the electric energy stored in the battery is exhausted, the labor cost for processing such a task is incurred because the manager has to replace the used battery daily. The second problem is that calorimeters applied to district heating systems are more likely to be exposed to high temperatures. Batteries typically have poor high temperature characteristics, resulting in shorter lifespans, which often requires frequent battery replacement and, in severe cases, no energy remaining in the batteries. Failure to measure may occur.

도 2는 본 발명의 일 실시예에 따른 열전 소자를 이용한 자가발전식 열량계의 내부 블록도이다.2 is an internal block diagram of a self-generating calorimeter using a thermoelectric device according to an embodiment of the present invention.

유량 측정부(210)는 배관을 통해 공급되는 유체의 양을 측정한다. 도 1을 참조할 때, 공급측 배관(130)에 설치되어 유체의 양(유량)을 측정할 수도 있고, 회수측 배관(140)에 설치되어 유량을 측정할 수도 있다. 유량 측정부(210)는 유량을 측정하는 일 예시 방법은 통과체적에 비례한 익차의 회전을 기어로 감속하여 일정 체적마다 전기적인 신호를 생성하고 이를 열량 계산부(230)로 송부하는 방법이다.The flow rate measuring unit 210 measures the amount of fluid supplied through the pipe. Referring to FIG. 1, the amount (flow rate) of the fluid may be measured by being installed in the supply side pipe 130, or may be installed in the recovery side pipe 140 to measure the flow rate. The flow rate measuring unit 210 is a method of measuring the flow rate is a method of reducing the rotation of the blade wheel proportional to the passing volume with a gear to generate an electrical signal for each predetermined volume and send it to the calorie calculation unit 230.
온도 측정부(220)는 공급측 배관(130)과 회수측 배관(140) 사이의 온도 차이를 측정한다. 각 배관의 온도는 RTD(Resistance Temperature Detector)를 이용한 센서를 사용하여 측정할 수 있다.The temperature measuring unit 220 measures a temperature difference between the supply side pipe 130 and the recovery side pipe 140. The temperature of each pipe can be measured using a sensor using RTD (Resistance Temperature Detector).
열량 계산부(230)는 유량 측정부(210)를 통해 측정된 유량값과 공급측 배관(130)과 회수측 배관(140) 사이의 온도 차이 측정값을 이용하여 공급되는 에너지량을 계산한다. Q = m x c x ΔT의 식에 따라 열량(Q)은 질량(m), 비열(c), 온도 변화의 값(ΔT)으로 계산되는데, 질량(m) 및 비열(c)은 유량과 유체의 종류(예, 물)에 따라 결정하고, 온도 변화의 값(ΔT)은 공급측 배관(130)과 회수측 배관(140) 사이의 온도 차이 측정값에 따라 결정한다.The calorific value calculating unit 230 calculates the amount of energy supplied using the flow rate value measured by the flow rate measuring unit 210 and the temperature difference measurement value between the supply side pipe 130 and the recovery side pipe 140. According to the equation Q = mxcx ΔT, the calorific value (Q) is calculated as the mass (m), the specific heat (c), and the value of the temperature change (ΔT), where the mass (m) and the specific heat (c) are the flow rate and type of fluid ( For example, water), and the value ΔT of the temperature change is determined according to the measured temperature difference between the supply pipe 130 and the recovery pipe 140.

열전 소자는 열과 전기의 상호 작용으로 나타나는 각종 효과를 이용한 소자의 총칭이다. 열전 소자를 이용하면 열을 전기 에너지로 변환할 수 있다. 열전 소자를 이용하여 열을 전기 에너지로 변환하는 것 중 일 예는 제베크 효과를 이용하는 것이다. 두 종류의 금속을 고리 모양으로 연결하고, 한쪽 접점을 고온, 다른 쪽을 저온으로 했을 때 그 회로에 전류가 생기는 현상을 제베크 효과라고 한다.A thermoelectric element is a generic term for a device using various effects represented by interaction between heat and electricity. Thermoelectric elements can be used to convert heat into electrical energy. One example of converting heat into electrical energy using a thermoelectric element is to use the Seebeck effect. The phenomenon of generating current in the circuit when two kinds of metals are connected in a ring shape and one contact is made high temperature and the other is made low temperature is called the Seebeck effect.
난방시스템의 경우 자가 발전부(240)는 열전 소자의 고온부를 공급측 배관(130)에 연결하고, 열전 소자의 저온부를 회수측 배관(140)에 연결하여 공급측 배관(130)과 회수측 배관(140) 사이에서 발생하는 온도 차이를 전기 에너지로 변환하여 이를 열량계(110)의 전원으로 제공한다.In the heating system, the self-generating unit 240 connects the high temperature part of the thermoelectric element to the supply side pipe 130 and the low temperature part of the thermoelectric element to the recovery side pipe 140 to supply the supply side pipe 130 and the recovery side pipe 140. The temperature difference generated between the) is converted into electrical energy to provide it as a power source of the calorimeter 110.
냉방시스템의 경우 난방시스템의 경우와는 반대로 공급측 배관(130)의 온도가 회수측 배관(140)의 온도보다 높으므로, 자가 발전부(240)는 열전 소자의 고온부를 회수측 배관(140)에 연결하고 열전 소자의 저온부를 공급측 배관(130)에 연결하여 회수측 배관(140)과 공급측 배관(130) 사이에서 발생하는 온도 차이를 전기 에너지로 변환하여 이를 열량계(110)의 전원으로 제공한다.In the case of the cooling system, as opposed to the heating system, since the temperature of the supply side pipe 130 is higher than the temperature of the recovery side pipe 140, the self-generating unit 240 performs the high temperature portion of the thermoelectric element to the recovery side pipe 140. And a low temperature part of the thermoelectric element is connected to the supply side pipe 130 to convert a temperature difference generated between the recovery side pipe 140 and the supply side pipe 130 into electrical energy and provide it as a power source of the calorimeter 110.

At this time, the fluid 330 contained in the supply-side piping 130 maintains a high temperature. The high temperature part of the thermoelectric element 360 included in the self-generating unit 240 is connected to the supply side pipe 130 to absorb heat from the high temperature fluid 330. In addition, the low temperature part, which is the other side of the thermoelectric element 360, is exposed to the air state as shown in FIG. The circuit is connected to use the electromotive force generated by the thermoelectric element 360 is installed between the supply side pipe 130 and the atmosphere in which the temperature difference occurs, and electrical energy is transferred to the calorimeter 110 through the circuit. The self-generating unit 240 may further include a predetermined conversion module to provide electrical energy generated by the thermoelectric element as a power source of the calorimeter 110. In general, since the electrical energy generated by the thermoelectric element may have an unstable voltage and current, the self-generation unit 240 further includes a stabilization circuit for stabilizing the voltage and current of the generated electrical energy to supply stable power. There may be.

Referring to FIG. 5, the fluid 530 containing the energy for cooling is introduced through the supply side pipe 130. At this time, the fluid 530 included in the supply-side piping 130 maintains a low temperature. The low temperature part of the thermoelectric element 360 included in the self-generating part 240 is connected to the supply side pipe 130 to discharge heat to the low temperature fluid 530. In addition, the high temperature part, which is the other side of the thermoelectric element 360, is exposed to the atmospheric state as shown in FIG. 5 to absorb heat from the atmosphere. The circuit is connected to use the electromotive force generated by the thermoelectric element 360 is installed between the supply side pipe 130 and the atmosphere in which the temperature difference occurs, and electrical energy is transferred to the calorimeter 110 through the circuit.

열량계(240)는 전술한 내부 블록들(210, 220, 230, 240) 이외에 에너지 저장 제어부(250) 및 에너지 저장 장치(260)를 더 포함할 수 있다.The calorimeter 240 may further include an energy storage controller 250 and an energy storage device 260 in addition to the aforementioned internal blocks 210, 220, 230, and 240.
에너지 저장 제어부(250)는 자가 발전부(240)에서 변환시키는 전기 에너지가 열량계(110)에서 소비되는 전기 에너지보다 많은 경우 에너지 저장 장치(260)로 저장하고 자가 발전부(240)에서 변환시키는 전기 에너지가 열량계(110)에서 소비되는 전기 에너지보다 적은 경우 에너지 저장 장치(260)에 저장된 전기 에너지를 열량계(110)로 공급한다.The energy storage controller 250 stores the energy stored in the energy storage device 260 when the electrical energy converted by the self-generation unit 240 is greater than the electrical energy consumed by the calorimeter 110 and converts the energy by the self-generation unit 240. When energy is less than the electrical energy consumed by the calorimeter 110, the electrical energy stored in the energy storage device 260 is supplied to the calorimeter 110.
도 3에 도시된 실시예에서, 겨울에는 공급측 배관(130)에 상시적으로 고온의 열수가 흐르고, 대기 온도는 상대적으로 낮은 온도일 수 있으나, 여름에는 난방을 하지 않고 목욕 등의 일시적인 사용을 위해 난방 시스템을 이용하기 때문에 공급측 배관(130)의 온도가 상시적으로 고온을 유지하기 어렵고 대기의 온도 또한 상대적으로 높을 수 있다. 따라서 겨울에는 열전 소자(360)를 이용한 전기 에너지 생성이 상당히 효과적으로 운용될 수 있으나, 여름에는 자칫 전원 공급 용량이 수요를 따라가지 못할 수도 있다. 이러한 것을 해결할 수 있는 보조 장치가 에너지 저장 장치(260) 및 에너지 저장 제어부(260)이다.In the embodiment shown in Figure 3, the hot water is constantly flowing to the supply-side piping 130 in winter, the atmospheric temperature may be a relatively low temperature, but in the summer for temporary use such as bathing without heating Since the heating system is used, the temperature of the supply pipe 130 may not always maintain a high temperature, and the temperature of the atmosphere may also be relatively high.
