The end of the inlet extension 213 is coupled to the first connection member 121 is connected to the heating flow environment path inside the heat exchange unit (100). Between the inlet extension 213 and the inner circumferential surface of the body 211, a space 211a through which the heating water circulates inside the heat exchange part 100 is formed.

따라서 상기 몸통(211) 내부에서는 난방수가 유입되는 경로(유입구연장부(213))와 난방수가 유출되는 경로(공간(211a))가 동일한 방향을 이루도록 동심구조로 이루어져 있다. 여기서 '동일한 방향'이란 난방수의 흐름방향을 의미하는 것이 아니라 난방수 경로가 형성된 구조물의 위치관계를 의미한다.Therefore, the inside of the body 211 has a concentric structure so that the heating water flow path (inlet extension 213) and the heating water flow path (space 211a) form the same direction. Here, 'the same direction' does not mean the flow direction of the heating water, but the positional relationship of the structure in which the heating water path is formed.

본 발명은 유입구(212)와 배출구(214)가 하나의 어댑터(210)에 일체로 형성되어 있어 이에 연결되는 배관구조를 간단하게 할 수 있다.In the present invention, since the inlet 212 and the outlet 214 are integrally formed in one adapter 210, the pipe structure connected thereto can be simplified.

상기 제1어댑터(210)의 몸통(211) 측부에는 보일러의 난방배관 내부에 난방수를 보충하기 위한 급수밸브와 연결되는 급수밸브연결구(215)가 형성되는 것이 바 람직하다. 급수밸브는 난방라인 내부에 난방수가 부족할 때 난방수를 추가로 공급하기 위한 것이다. 종래에는 급수밸브를 난방배관에 연결하기 위한 별도의 배관구조를 채택하였으나 본 발명의 경우 제1어댑터(210)에 일체형으로 이루어진 급수밸브연결구(215)를 구비함으로써 배관구조가 간단해진다.It is preferable that the water supply valve connector 215 connected to the water supply valve for replenishing the heating water is formed in the body 211 side of the first adapter 210. The water supply valve is for supplying additional heating water when the heating water is insufficient in the heating line. Conventionally, a separate piping structure for connecting the water supply valve to the heating pipe is adopted, but in the case of the present invention, the piping structure is simplified by providing the water supply valve connector 215 formed integrally with the first adapter 210.

또한 상기 제1어댑터(210)에는 난방환수연결구(216)가 형성되는 것이 바람직하다. 난방환수연결구(216)는 난방환수가 흐르는 난방배관 측과 연결된다. 난방환수연결구(216)를 통해 유입된 난방환수는 배출구(214)를 통해 순환펌프(10) 측으로 공급된다.In addition, the first adapter 210 is preferably a heating return connector 216 is formed. The heating return connector 216 is connected to the heating pipe side through which the heating return flows. The heating return water introduced through the heating return connector 216 is supplied to the circulation pump 10 through the discharge port 214.

도 6a,b,c을 참조하여 제2어댑터(220)의 구성에 대하여 설명한다.A configuration of the second adapter 220 will be described with reference to FIGS. 6A, B, and C. FIG.

제2어댑터(220)에는, 몸통(221)과, 직수가 유입되는 유입구(222)와, 몸통(221) 내부에 위치되어 일측 끝단이 유입구(222)에 연결되고 타측 끝단이 제2연결부재(122)에 결합되는 유입구연장부(223)와, 열교환부(100) 내부를 순환한 직수가 배출되는 배출구(224)가 형성되어 있다. 상기 몸통(221), 유입구(222), 유입구연장부(223) 및 배출구(224)의 형상은 제1어댑터(210)와 동일하다.In the second adapter 220, the body 221, the inlet 222 through which direct water flows, and the inside of the body 221, one end is connected to the inlet 222, and the other end is connected to the second connection member ( An inlet extension 223 coupled to 122 and an outlet 224 through which direct water circulated through the heat exchanger 100 are discharged are formed. The body 221, the inlet 222, the inlet extension 223, and the outlet 224 have the same shape as the first adapter 210.

따라서 상기 몸통(221) 내부에서는 직수가 유입되는 경로(유입구연장부(223))와 온수가 유출되는 경로(공간(221a))가 동일한 방향을 이루도록 동심구조로 이루어져 있다.Therefore, the body 221 has a concentric structure in which a path through which direct water flows (inlet extension 223) and a path through which hot water flows (space 221a) form the same direction.

상기 제2어댑터(220)의 몸통(221) 측부에는 급수밸브와 연결되는 급수밸브연결구(225)가 형성되는 것이 바람직하다. It is preferable that a water supply valve connector 225 connected to the water supply valve is formed at the body 221 side of the second adapter 220.

FIG. 11 is a schematic view showing the flow of heating water and direct water in a state in which the heat exchanger structure shown in FIG. 11 and the heat exchanger structure shown in FIG. 11 are combined.

도 10, 도 11, 도 12에 도시된 제1어댑터(210)와 제2어댑터(220)는 유입구(212,222), 배출구(214,224), 급수밸브연결구(215,225) 및 난방환수연결구(216)가 도 5 및 도 6에 도시된 어댑터(210,220)의 위치와 상이하나 이는 설명의 편의를 위한 것이다. 또한 제1어댑터(210)와 제2어댑터(220)의 형상이 도 5, 도 6에 도시된 형상으로 한정되는 것은 아니고, 도 10 내지 도 12에 도시된 형상으로 구현하는 것도 가능하다.10, 11, and 12, the first adapter 210 and the second adapter 220 have inlets 212 and 222, outlets 214 and 224, water supply valve connectors 215 and 225, and a heating return connector 216. Although different from the position of the adapters 210 and 220 shown in FIG. 5 and FIG. 6, this is for convenience of description. In addition, the shapes of the first adapter 210 and the second adapter 220 are not limited to the shapes shown in FIGS. 5 and 6, but may be implemented in the shapes shown in FIGS. 10 to 12.

도 10 내지 도 12를 참조하여 난방수와 직수의 경로에 대해 설명한다.A path between heating water and direct water will be described with reference to FIGS. 10 to 12.

삼방밸브(30)가 온수모드로 전환되면, 주열교환기(20)에서 가열된 난방수는 난방소요처 측으로 흐름이 차단되고 급탕열교환기(1) 측으로 공급되어 제1어댑터(210)의 유입구(212) 및 유입구연장부(213) 내부로 유입된다. When the three-way valve 30 is switched to the hot water mode, the heating water heated in the main heat exchanger 20 is cut off to the heating source side and supplied to the hot water heat exchanger 1 side to supply the inlet 212 of the first adapter 210. ) And the inlet extension 213 is introduced into the interior.

제1어댑터(210)로 유입된 난방수는 열교환부(100)의 제1난방수순환경로(131)와 제2난방수순환경로(132)를 순차 통과하면서 제1직수순환경로(133) 및 제2직수순환경로(134) 내부를 흐르는 직수와 열교환이 이루어져 온도가 하락한 상태에서 배출구(214)를 통해 팽창탱크(50)로 배출된다.The heating water introduced into the first adapter 210 passes through the first heating water environment path 131 and the second heating water environment path 132 of the heat exchange part 100 in sequence, and then the first direct water environment path 133 and Heat is exchanged with the direct water flowing in the second direct pure environment path 134 and discharged to the expansion tank 50 through the outlet 214 in a state where the temperature is decreased.

이와 동시에 직수는 제2어댑터(220)의 유입구(222) 및 유입구연장부(223) 내부로 유입된다. 제2어댑터(220)로 유입된 난방수는 열교환부(100)의 제1직수순환경 로(133) 및 제2직수순환경로(134)를 순차 통과하면서 제1난방수순환경로(131)와 제2난방수순환경로(132) 내부를 흐르는 난방수와 열교환이 이루어져 온수가 된 상태에서 배출구(224)를 통해 온수소요처 측으로 배출된다.At the same time, water flows into the inlet 222 and the inlet extension 223 of the second adapter 220. The heating water introduced into the second adapter 220 passes through the first direct environmental environment path 133 and the second direct environmental environment path 134 of the heat exchange part 100 and the first heating environment environmental path 131. The heat exchange is performed with the heating water flowing in the second heating water environment path 132 and discharged to the hot water source through the outlet 224 in the state where the water is hot.

한편 삼방밸브(30)가 난방모드로 전환되면 난방소요처로 공급된 난방수는 열교환과정이 이루어진 후 순환펌프(10) 측으로 환수된다. 본 발명에서는 순환펌프(10) 측으로 환수되는 난방환수를 제1어댑터(210)의 난방환수연결구(216)로 유입시켜 배출구(214)를 거쳐, 팽창탱크(50)를 통해 순환펌프(10) 측으로 환수되도록 하였다.Meanwhile, when the three-way valve 30 is switched to the heating mode, the heating water supplied to the heating source is returned to the circulation pump 10 after the heat exchange process is performed. In the present invention, the heating return water returned to the circulation pump 10 to the heating return connector 216 of the first adapter 210 through the outlet 214, through the expansion tank 50 to the circulation pump 10 side To be returned.

만약 난방배관 내부에 난방수가 부족한 경우 급수밸브(300)를 개방시켜 난방수를 보충하게 된다. 급수밸브(300)는 제1어댑터(210)의 급수밸브연결구(215)와 제2어댑터(220)의 급수밸브연결구(225) 사이에 설치된다. 따라서 급수밸브(300)를 개방시키면 제2어댑터(220)의 몸통(221) 내부의 온수 중 일부가 급수밸브연결구(225)를 통해 제1어댑터(210)의 급수밸브연결구(215)와 배출구(214)를 순차 경유한 후 환수 측의 난방배관으로 공급된다.If the heating water is insufficient in the heating pipe to open the water supply valve 300 to replenish the heating water. The water supply valve 300 is installed between the water supply valve connector 215 of the first adapter 210 and the water supply valve connector 225 of the second adapter 220. Therefore, when the water supply valve 300 is opened, some of the hot water in the body 221 of the second adapter 220 passes through the water supply valve connector 215 and the discharge port (215) of the first adapter 210 through the water supply valve connector 225. After passing through 214 in sequence, it is supplied to the heating pipe on the return side.
