이하에서는, 이와 같이 구성된 본 실시 예의 작용 및 효과에 대해 설명한다.Hereinafter, the operation and effects of the present embodiment configured as described above will be described.

제1순환펌프(130)의 구동으로 열매체순환관(P1)을 통해 열교환매체가 순환된다. 즉, 집열판(10)에서 가열된 열교환매체는 축열탱크(20)내의 제1교환기(30)에서 난방용수와 열교환되고, 난방용수는 가열된다.The heat exchange medium is circulated through the heat medium circulation pipe P1 by the driving of the first circulation pump 130. That is, the heat exchange medium heated in the heat collecting plate 10 is heat-exchanged with the heating water in the first exchanger 30 in the heat storage tank 20, and the heating water is heated.

제2순환펌프(190)의 구동으로 난방용수 순환관(P6)을 통해 가열된 난방용수는 순환된다. 가열된 난방용수는 제2열교환기(40)에서 난방지역을 난방하고 축열탱크(20)로 복귀된다.The heating water heated through the heating water circulation pipe P6 by the driving of the second circulation pump 190 is circulated. The heated heating water heats the heating zone in the second heat exchanger 40 and returns to the heat storage tank 20.

원수공급관(P8)을 통해 제3교환기(50)에 외부 원수를 공급하게 되면, 제3교환기(50)에서 외부 원수가 난방용수와의 열교환으로 가열되어 원수배출관(P9)으로 배출된다. 이에, 난방용수와 함께 온수를 사용할 수가 있다.When the external raw water is supplied to the third exchanger 50 through the raw water supply pipe P8, the external raw water is heated by heat exchange with the heating water in the third exchanger 50 and discharged to the raw water discharge pipe P9. Thus, hot water can be used together with the heating water.

한편, 난방용수의 수요가 적을 때에는 난방용수가 적정온도로 축열탱크(20)내에 소비되지 않고 저장되어 있어, 집열판(10)에서 지속적으로 가열되는 열교환매체에 의해 열교환매체와 난방용수의 온도는 지속적으로 상승하게 된다.On the other hand, when the demand for the heating water is low, the heating water is stored without being consumed in the heat storage tank 20 at an appropriate temperature, and the temperature of the heat exchange medium and the heating water is continuously maintained by the heat exchange medium that is continuously heated in the heat collecting plate 10. Will rise.

이러한 온도상승으로 인해 열교환매체는 부피가 증가되고, 이에 따른 열매체순환관(P1)내의 압력이 증가하게 된다. 이때, 부피와 압력이 증가된 열교환매체는 분기관(P2)을 통해 밀폐형팽창탱크(90)로 유입되고, 안전하게 열매체순환관(P1)을 순환하게 된다. Due to such a temperature rise, the heat exchange medium increases in volume, thereby increasing the pressure in the heat medium circulation pipe (P1). At this time, the heat exchange medium with increased volume and pressure flows into the hermetic expansion tank 90 through the branch pipe P2, and safely circulates the heat medium circulation pipe P1.

그러나, 밀폐형팽창탱크(90)에 과부하가 발생될 경우에는 열교환매체의 증가된 압력에 의해 압력밸브(170)가 온상태가 되어 연결관(P4)이 개통되고 열교환매체는 열매체보충탱크(120)로 바이패스된다.However, when an overload occurs in the hermetic expansion tank 90, the pressure valve 170 is turned on by the increased pressure of the heat exchange medium so that the connection pipe P4 is opened and the heat exchange medium is the heat medium supplement tank 120. Bypassed.

또한, 밀폐형팽창탱크(90)의 과부하 발생될 경우, 온도측정수단(101) 및 압력측정수단(102)에 의해 열교환매체의 물리적 변화가 감지된다. 콘트롤부(80)는 온도측정수단(101) 및 압력측정수단(102)으로부터 감지신호를 수신받아, 설정된 열교환매체의 온도값 및 압력값보다 이상일 경우에는 냉각수단(110)의 송풍기(112)에 온신호를 송신함과 아울러, 제1삼방밸브(180)를 제어하여 열교환매체가 축열탱크(20) 대신에 냉각수단(110)을 경유하도록 한다.In addition, when an overload of the hermetic expansion tank 90 occurs, the physical change of the heat exchange medium is sensed by the temperature measuring means 101 and the pressure measuring means 102. The control unit 80 receives the detection signals from the temperature measuring means 101 and the pressure measuring means 102, and if it is greater than the temperature value and the pressure value of the set heat exchange medium, the control unit 80 to the blower 112 of the cooling means 110. In addition to transmitting the on-signal, the first three-way valve 180 is controlled to allow the heat exchange medium to pass through the cooling means 110 instead of the heat storage tank 20.

따라서, 열교환매체는 냉각수단(110)에 의해 냉각되어 부피 및 압력이 감소된다.Thus, the heat exchange medium is cooled by the cooling means 110 to reduce the volume and pressure.

냉각수단(110)의 구동은 온도측정수단(101)에 의해 측정된 온도값이 설정된 최저온도값에 도달할 때까지 이루어지고, 제1삼방밸브(180)는 냉각수단(110)의 구동이 오프(OFF)될 때, 콘트롤부(80)의 제어에 의해 열교환매체가 축열탱크(20)를 경유하도록 한다.The driving of the cooling means 110 is made until the temperature value measured by the temperature measuring means 101 reaches a set minimum temperature value, and the first three-way valve 180 is turned off. When it is turned off, the heat exchange medium passes through the heat storage tank 20 under the control of the control unit 80.

열교환매체의 보충은 제1밸브(150)는 오프(OFF)시키고, 제2밸브(160)는 온(ON)시킨다.The replenishment of the heat exchange medium turns off the first valve 150 and turns on the second valve 160.

이때, 열교환매체는 폐회로관(P3)으로 이송되어 열매체보충탱크(120)를 경유하게 된다. 그리고, 공급펌프(140)를 구동시키면, 열매체보충탱크(120)에 저장된 열교환매체가 열매체순환관(P1)에 공급된다.At this time, the heat exchange medium is transferred to the closed circuit pipe (P3) to pass through the heat medium supplement tank (120). Then, when the supply pump 140 is driven, the heat exchange medium stored in the heat medium supplement tank 120 is supplied to the heat medium circulation pipe P1.

한편, 난방용수의 수요가 많거나, 집열판(10)에 의해 열교환매체를 충분히 가열할 수 없는 경우에는 난방용수의 온도가 낮아지게 된다.On the other hand, when the demand for heating water is high or the heat exchange medium cannot be sufficiently heated by the heat collecting plate 10, the temperature of the heating water is lowered.

이때, 난반용수 온도측정부(70)에 의해 측정된 난방용수의 온도값을 수신받은 콘트롤부(80)는 설정된 난방용수 온도값보다 낮은 측정값이 수신되면, 보조열원부(60)와 제2,3삼방밸브(200,210)를 제어하게 된다.At this time, the control unit 80 receiving the temperature value of the heating water measured by the diffused water temperature measuring unit 70, when a measurement value lower than the set heating water temperature value is received, the auxiliary heat source unit 60 and the second The three-way valve (200, 210) will be controlled.

즉, 난방용수는 축열탱크(20)를 경유하지 않고, 난방지역과 보조열원부(60)를 경유하여 순환되며, 보조열원부(60)에 의해 가열된다. That is, the heating water is circulated through the heating zone and the auxiliary heat source unit 60 without passing through the heat storage tank 20, and is heated by the auxiliary heat source unit 60.

또한, 외부원수는 제3열교환기(50)를 경유하지 않고, 보조열원부(60)를 경유하게 되며, 보조열원부(60)에 의해 가열된다.In addition, the external source water passes through the auxiliary heat source unit 60 without passing through the third heat exchanger 50 and is heated by the auxiliary heat source unit 60.

이와 같이, 난방용수의 수요가 많거나 집열판에 의해 열교환매체가 충분히 가열되지 못할 경우에는 보조열원부에 의해 난방용수 및 외부원수를 가열하여, 난방지역을 난방하고, 온수를 사용할 수가 있게 된다.As such, when the demand for the heating water is high or the heat exchange medium is not sufficiently heated by the heat collecting plate, the heating water and the external raw water are heated by the auxiliary heat source unit to heat the heating area and use hot water.
