공동주택 노후배관 철거 및 신설배관을 이용한 온수 및 난방수 공급방법{Removing old pipes and supplying hot water and heating water using new pipes}Removing old pipes and supplying hot water using new pipes {Removing old pipes and supplying hot water and heating water using new pipes}

본 발명은 공동주택 노후배관 철거 및 신설배관을 이용한 온수 및 난방수 공급방법에 관한 것으로서, 더욱 상하게는 난방 및 급탕이 분리된 방식에서 공급과 회수용으로 총 4개의 배관이 사용되는데, 이들 관들의 노후 시 전부 철거하고 2개의 신설배관으로 각 세대의 세대난방열교환기에 연결하여 바닥난방을 하되 각 세대의 급탕은 세대난방열교환기를 거치지 않고 신설배관과 직접 연결함으로써, 급탕이 빠르게 이뤄져서 열손실이 발생되지 않는 공동주택 노후배관 철거 및 신설배관을 이용한 온수 및 난방수 공급방법에 관한 것이다.The present invention relates to a method for supplying hot water and heating water using a decommissioned pipe of an old house and a new pipe, and moreover, a total of four pipes are used for supply and recovery in a manner in which heating and hot water are separated. When the old age is removed, two new pipes are connected to each generation heating heat exchanger for floor heating, but the hot water supply of each household is directly connected to the new piping without passing through the generation heating heat exchanger. The present invention relates to a method of supplying hot water and heating water using a decommissioned old pipe which is not a multi-family house and a new pipe.

일반적으로 아파트 같은 공동주택은 난방과 급탕을 위해 중앙난방시스템이 사용되고 있는데, 이는 기계실에서 대형 산업용 보일러로 물을 데워 난방수와 급탕수를 각각 난방라인과 급탕라인을 통해 각 세대별로 공급한다. 또한 열병합발전 등의 지역난방을 이용하는 경우 열병합발전소로부터 전달되는 난방수와 급탕수를 기계실에서 각 세대별로 공급하여 난방과 급탕이 이루어지도록 되어 있다.In general, apartment houses such as apartments are used with central heating system for heating and hot water supply, which is heated by a large industrial boiler in a machine room and supplies heating water and hot water for each household through heating lines and hot water supply lines, respectively. In addition, when using district heating such as cogeneration, heating and hot water supplied from the cogeneration plant are supplied for each household in the machine room to perform heating and hot water supply.

그러나 배관에 물이 흐르기 때문에 20년 이상 된 장기 주택의 경우 배관 내부의 부식으로 물 순환이 원활하지 않으므로 이를 철거하고 새로 시설해야 되나, 4개의 배관을 전부 교체하는데 비용이 많이 소요되는 단점이 있었다.However, since water flows through the pipes, long-term houses over 20 years old have to be removed and newly installed due to corrosion inside the pipes. However, it is expensive to replace all four pipes.

이를 감안하여 국내특허 제1113160호는 급탕 배관은 계절과 무관하게 계속사용하여 내부 부식이 덜 된다는 점에 착안하여 난방에 이용되는 배관 2개는 폐쇄하고 급탕에 이용되는 배관으로 난방과 급탕이 동시에 이뤄지도록 한 난방공급장치 및 방법을 제안한 바 있다.In view of this, Korean Patent No. 1113160 cautions that hot water supply pipes continue to be used regardless of the season to reduce internal corrosion. Therefore, the two pipes used for heating are closed, and the heating and hot water supply is simultaneously performed. A heating supply system and method have been proposed.

그러나 급탕용 공급관은 층별로 관의 직경이 점차 줄어들게 되어 있어 세대별 온수의 공급에는 문제가 없으나, 회수관은 단일 직경으로 되어 있으므로 회수시 정체가 발생된다. 때문에 온수의 회수시간이 많이 걸리므로 세대별 설치된 열교환기에서 온수와의 열교환이 빠르게 이뤄지지 않으므로 혹한기에는 난방효율이 저하되는 기술적인 문제점이 있었다. 또한 최상층의 경우 위쪽 세대가 없어서 최상층과 연결된 공급관에 온수의 정체가 발생되지 않으므로 최상층의 열교환기는 다른 층보다 온수가 빠르게 흘러 열교환효율이 떨어지므로 바닥난방을 충분히 할 수 없는 단점이 있었다.However, the hot water supply pipe has a problem that the diameter of the pipe gradually decreases by layer, so there is no problem in the supply of hot water by generation, but since the recovery pipe has a single diameter, congestion occurs during recovery. Because the recovery time of the hot water takes a lot, since the heat exchange with the hot water is not made quickly in the heat exchanger installed by generation, there was a technical problem that the heating efficiency is lowered in the cold season. In addition, in the top floor, since there is no upper generation, congestion of hot water does not occur in the supply pipe connected to the top floor, the heat exchanger of the top floor has a disadvantage in that it cannot sufficiently heat the floor because the hot water flows faster than other floors.

종래 특허 제1040693호는 세대별로 급탕열교환기를 추가하여 급탕하지 않는 온수가 메인열교환기로 환수되도록 하여 바닥난방 효율이 향상되도록 한 난방 및 급탕 시스템을 제안한 바 있다.Conventional Patent No. 1040693 has proposed a heating and hot water supply system to improve floor heating efficiency by adding a hot water heat exchanger for each generation so that hot water not hot water is returned to the main heat exchanger.

그러나 종래 특허의 경우 급탕열교환기를 추가해야 되므로 시설비가 많이 들고 또한 기계실에서 공급되는 온수가 급탕열교환기를 거쳐 메인열교환기로 순환되는 방식으로써, 상기 급탕열교환기에 별도 열원이 공급되지 않으므로 총 열량이 동일하여 난방효율을 높이는데 한계가 있었다. 또한 최상층의 경우 여전히 수두차로 인한 수압이 발생되지 않으므로 최상층으로 공급되는 온수는 급탕열교환기와 메인열교환기를 빠르게 통과하므로 최상층은 열교환효율이 떨어지는 등의 문제점이 있었다.However, in the case of the conventional patent, since a hot water supply heat exchanger must be added, the facility cost is high, and the hot water supplied from the machine room is circulated to the main heat exchanger through the hot water heat exchanger. There was a limit to increasing the efficiency. In addition, in the case of the top floor, since the water pressure is not generated due to the water head difference, the hot water supplied to the top floor passes quickly through the hot water supply heat exchanger and the main heat exchanger.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 난방 및 급탕이 분리된 방식에서 공급과 회수용으로 총 4개의 배관이 사용되는데, 이들 관들의 노후 시 전부 철거하고 2개의 신설배관으로 각 세대의 세대난방열교환기에 연결하여 바닥난방을 하되 각 세대의 급탕은 세대난방열교환기를 거치지 않고 신설배관과 직접 연결함으로써, 급탕이 빠르게 이뤄져서 열손실이 발생되지 않는 공동주택 노후배관 철거 및 신설배관을 이용한 온수 및 난방수 공급방법을 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is that a total of four pipes are used for supply and recovery in a separate heating and hot water supply system. The floor heating is connected to each household heating heat exchanger by piping, and each household's hot water supply is directly connected to the new pipe without passing through the household heating heat exchanger, so that the hot water supply takes place quickly. It is to provide a hot water and heating water supply method using the new pipe.

이를 위하여 본 발명은 기계실의 난방열교환기 및 급탕열교환기로부터 최상층까지 연결된 2개의 난방관 및 2개의 급탕관을 모두 철거하고 상기 난방열교환기 및 급탕열교환기를 병렬로 연결하는 신설공급관 및 신설회수관을 최상층까지 배관하며; 상기 신설회수관에는 2개의 인버터 순환펌프가 병렬로 설치되어서 제어부를 통하여 공급온도와 회수온도차에 따라 운전속도가 자동 제어되고; 층별 세대는 난방분배기가 세대난방열교환기를 통하여 상기 신설공급관 및 신설회수관에 연결되는 공동주택 노후배관 철거 및 신설배관을 이용한 온수 및 난방수 공급방법에 있어서, 기계실 쪽의 상기 신설회수관에 상수도관을 연결하여서 상기 난방열교환기 및 급탕열교환를 거쳐 상기 신설공급관으로 먹을 수 있는 수돗물이 온수로 변환되어 공급되도록 하는 단계; 층별 세대에는 상기 세대난방열교환기를 거치지 않고 상기 신설공급관에 직접 연결되는 신설급탕관을 설치하여서 주방 및 화장실에 먹을 수 있는 수돗물 온수가 직접 공급되도록 하는 단계; 그리고 상기 신설공급관과 신설회수관의 직경은 층별 1 : 1의 비율로 저층에서 고층으로 갈수록 줄어들게 하고, 그 직경은 각 층별 세대수 및 최상층 높이에 따라 결정되며, 수돗물 온수 사용량만큼 상기 상수도관에서 상기 신설회수관으로 수돗물이 보충되도록 하는 단계들로 이루어진 특징이 있다.To this end, the present invention dismantles two heating pipes and two hot water supply pipes connected to the top floor from the heating heat exchanger and the hot water heat exchanger in the machine room, and connects the new supply pipe and the new recovery pipe connecting the heating heat exchanger and the hot water heat exchanger in parallel to the top floor. Pipe; The new recovery pipe is provided with two inverter circulation pumps in parallel so that the operation speed is automatically controlled according to the supply temperature and the recovery temperature difference through the control unit; In the household for each floor, in the hot water and heating water supply method using the old house pipe dismantling and the new pipe in which the heating distributor is connected to the new supply pipe and the new recovery pipe through the household heating heat exchanger, the water pipe is connected to the new recovery pipe on the machine room side. Connecting the edible tap water to the newly-supplied supply pipe through the heating heat exchanger and the hot water heat exchange to convert the hot water into hot water; A floor-to-floor generation, by installing a new hot water supply pipe directly connected to the new supply pipe without passing through the household heating heat exchanger to directly supply hot water to be eaten in a kitchen and a bathroom; And the diameter of the new supply pipe and the new recovery pipe is reduced from the lower floor to the higher floor at a ratio of 1: 1 per floor, the diameter is determined according to the number of generations and the top floor of each floor, the new water in the water pipe as much as the use of tap water It is characterized by consisting of steps to replenish the tap water to the return pipe.

본 발명에 따르면 기존 난방과 급탕용으로 사용되는 4개의 배관을 전부 철거하고 신설배관 2개로 온수의 공급과 회수가 이뤄지도록 신설공급관과 신설회수관을 층별로 1 : 1의 직경을 갖도록 하였으며, 각 층은 신설공급관과 연결되는 세대난방열교환기를 통하여 난방이 이뤄지고, 각 층의 급탕은 상기 세대난방열교환기를 거치지 않고 상기 신설공급관에 직접 연결하여 온수가 공급되도록 하였다.According to the present invention, all four pipes used for the existing heating and hot water supply were removed, and the new supply pipe and the new collection pipe had a diameter of 1: 1 for each floor so that hot water was supplied and recovered by two new pipes. The floor is heated through a generation heating heat exchanger connected to the new supply pipe, and the hot water supply of each floor is directly connected to the new supply pipe without passing through the generation heating heat exchanger to supply hot water.

기계실의 열교환기와 연결된 상기 신설공급관 및 신설회수관 중에서 상기 신설회수관에 상수도관이 연결되어서 수돗물이 온수로 생산되기 때문에 각 세대는 급탕용 온수를 직접 공급받을 수 있으므로 종래 열교환기를 거쳐 간접 열교환 하던 방식에 비하여 급탕이 신속하게 이뤄진다. 또한 저층에서 고층으로 갈수록 공급배관 및 회수배관의 직경이 점차 줄어들기 때문에 저층에서 급탕으로 온수가 사용되더라도 고층까지 온수가 충분히 공급되며, 사용 후 남은 온수가 회수배관으로 빠르게 순환되므로 정체가 발생되지 않아 2개의 배관으로 난방과 급탕이 부족하지 않으며, 특히 최상층의 경우 수두차를 갖는 리턴배관을 추가하여 최상층의 세대난방열교환기로 흐르는 온수가 혹한기에 느려져 충분한 열교환이 되므로 최상층 바닥난방에 어려움이 없는 등의 이점이 있다.Since the tap water is produced as hot water from the new supply pipe and the new recovery pipe connected to the heat exchanger of the machine room, the tap water is produced as hot water, so each generation can be directly supplied with hot water for hot water supply. Compared to the quick hot water supply. In addition, since the diameters of the supply and recovery pipes are gradually reduced from the lower floor to the higher floor, even if hot water is used as the hot water supply from the lower floor, the hot water is sufficiently supplied to the high floor. There are no shortages of heating and hot water supply with two pipes. Especially, in the case of the top floor, the return pipe with water head difference is added. There is an advantage.

도 1 내지 도 2에서 본 발명 한 실시예의 온수 및 난방수 공급방법이 적용된 난방시스템은 열병합발전소에서 공급되는 온수가 난방관 및 급탕관을 통하여 난방열교환기(10) 및 급탕열교환기(11)로 순환되는데, 상기 난방열교환기(10) 및 급탕열교환기(11)는 기존에 사용하던 것으로서 신설공급관(20) 및 신설회수관(21)에 병열렬로 연결된다. 그리고 신설회수관(21)에는 2개의 인버터 순환펌프(12)가 병열로 설치되어서 제어부(14)를 통하여 공급온도와 회수온도차에 따라 운전속도가 자동 제어된다.1 to 2, in the heating system to which the hot water and heating water supplying method of the present invention is applied, hot water supplied from a cogeneration plant is circulated to a heating heat exchanger 10 and a hot water supply heat exchanger 11 through a heating tube and a hot water supply tube. The heating heat exchanger 10 and the hot water supply heat exchanger 11 are connected in parallel to the new supply pipe 20 and the new recovery pipe 21 as previously used. The new recovery pipe 21 is provided with two inverter circulation pumps 12 in parallel so that the operation speed is automatically controlled according to the supply temperature and the recovery temperature difference through the control unit 14.

상기 신설공급관(20) 및 신설회수관(21)은 기존 2개의 공급관 및 2개의 회수관을 철거하고 새롭게 배관한 것으로서, 각 세대를 관통하여 최상층까지 시공된다. 상기 신설공급관(20)과 신설회수관(21)은 층별로 1 : 1의 비율로 직경이 동일한데, 저층에서 고층으로 갈수록 줄어들게 최저층 60mm 에서 최상층 25mm 까지 범위 내에서 다양한 직경으로 구성되며, 이들 직경은 각 층별 세대수 및 최상층 높이에 따라 결정된다.The new supply pipe 20 and the new recovery pipe 21 are removed by newly dismantling two existing supply pipes and two recovery pipes, and are constructed up to the top floor through each generation. The new supply pipe 20 and the new recovery pipe 21 have the same diameter at a ratio of 1: 1 for each floor, and are composed of various diameters within the range from the lowest layer 60mm to the top layer 25mm so as to decrease from the lower layer to the higher layer. Depends on the number of households in each floor and the height of the top floor.

또한 층별 세대마다 동일 구성으로 난방시스템이 적용되는데, 각 세대는 신설공급관(20) 및 신설회수관(21)에 연결되는 세대난방열교환기(30)를 갖는다. 상기 세대난방열교환기(30)에는 순환펌프(31)가 내장되어서 세대의 난방분배기(33)와 연결되어 각방 바닥난방이 이뤄지며, 각 세대는 상기 세대난방열교환기(30)를 거치지 않고 상기 신설공급관(20)과 직접 연결되는 신설급탕관(22)이 추가되어서 급탕을 필요로하는 주방 및 화장실의 온수관과 연결된다. 그리고 상기 세대난방열교환기(30)에는 난방밸브(32)가 구비되어서 실내온도조절기(36)와 연결되고 각방의 설정된 온도에 맞게 상기 난방밸브(32)를 개폐하여 상기 난방분배기(33)로 순환되는 온수량을 제어한다.In addition, the heating system is applied in the same configuration for each floor generation, each generation has a generation heating heat exchanger (30) connected to the new supply pipe (20) and the new recovery pipe (21). The household heating heat exchanger (30) has a built-in circulation pump 31 is connected to the heating distributor (33) of the household to achieve a floor heating, each generation is the new supply pipe 20 without passing through the household heating heat exchanger (30) ) Is directly connected to the new hot water supply pipe 22 is connected to the hot water pipes of the kitchen and toilet requiring hot water. In addition, the generation heating heat exchanger (30) is provided with a heating valve (32) connected to the room temperature controller (36), opening and closing the heating valve (32) according to the set temperature of each room and circulated to the heating distributor (33). Control the amount of hot water.

또한 최상층의 경우 한층 더 높게 리턴배관(23)이 추가되어 신설공급관(20) 및 신설회수관(21)에 연결되며, 그 직경은 최상층 신설공급관(20) 및 신설회수관(21) 보다 작은 10 ∼ 15mm로써, 상기 제어부(14)를 통하여 개폐가 조절되는 자동밸브(24)가 설치된다. 상기 리턴배관(23)은 최상층의 세대난방열교환기(30)와 신설공급관(20) 사이에 수두차(水頭差)로 인한 수압을 받도록 한 것으로서, 겨울철 상기 자동밸브(24)를 최대 90%까지 닫아 상기 리턴배관(23)으로 흐르는 온수에 정체가 발생되도록 한 것이다. 따라서 최상층 세대난방열교환기(30)로 흐르는 온수가 리턴배관(23)에서 환수되는 온수와 신설회수관(21)에서 합쳐지기 때문에 유속이 느려져 세대난방열교환기(30)에서 충분한 열교환이 이뤄지므로 겨울철 혹한기 바닥난방이 효율적으로 이뤄진다.In addition, in the case of the uppermost floor, a return pipe 23 is added to the new supply pipe 20 and the newly recovered pipe 21 so that the diameter of the uppermost floor is smaller than that of the newly installed supply pipe 20 and the newly recovered pipe 21. As to 15mm, the automatic valve 24 which opens and closes through the said control part 14 is provided. The return pipe 23 is to receive the water pressure due to the water head difference between the generation heating heat exchanger 30 and the new supply pipe 20 of the uppermost floor, and close the automatic valve 24 in winter by up to 90% The congestion is generated in the hot water flowing into the return pipe (23). Therefore, since the hot water flowing to the top floor generation heat exchanger (30) is combined with the hot water returned from the return pipe 23 and the new recovery pipe (21), the flow rate is slow, so that sufficient heat exchange is made in the generation heat exchanger (30), so the bottom of the cold season in winter Heating is done efficiently.

이처럼 구성된 본 발명 한 실시예의 난방시스템은 기존의 난방관 2개와 급탕관 2개를 철거하고 새로운 신설공급관(20)과 신설회수관(21)을 기계실에서 최상층 까지 배관한 것으로서 기계실에는 기존의 난방열교환기(10) 및 급탕열교환기(11)가 신설된 관들과 병열로 연결되고 신설회수관(21)에는 2개의 인버터 순환펌프(12)가 병설되어 제어부(14)를 통하여 온수 온도에 따라 운전속도가 조절된다.The heating system according to the embodiment of the present invention configured as described above is to remove two existing heating pipes and two hot water supply pipes, and pipe a new supply pipe 20 and a new recovery pipe 21 from the machine room to the top floor. (10) and the hot water supply heat exchanger (11) are connected in parallel with the newly established pipes, and the new recovery pipe (21) is provided with two inverter circulation pumps (12) in parallel with the operation speed according to the hot water temperature through the control unit (14). Adjusted.

열병합발전소에서 공급되는 100도 내외의 고온수는 상기 난방열교환기(10) 및 급탕열교환기(11)로 순환되는데, 이들 열교환기는 신설공급관(20) 및 신설회수관(21)에 병렬로 연결된다. 그리고 상기 신설회수관(21)에는 상수도관(13)이 연결되어서 수돗물이 각 열교환기(10)(11)를 거쳐 신설공급관(20)으로 순환되는 과정에서 먹을 수 있는 깨끗한 물이 온수로 변환된다. 따라서 각 세대에서 세대난방열교환기(30)를 거치지 않고 신설급탕관(22)에서 직접 온수를 공급받아 사용할 수 있기 때문에 종래 열교환기를 거치는 간접 가열방식에 비하여 온수공급이 빠르게 이뤄지고, 또한 급탕으로 사용된 온수량 만큼 상수도관(13)에서 수돗물이 계속 보충되어 난방열교환기(10) 및 급탕열교환기(11)에서 가열되므로 온수공급에 차질이 발생되지 않는다.The hot water of about 100 degrees supplied from the cogeneration plant is circulated to the heating heat exchanger 10 and the hot water supply heat exchanger 11, and these heat exchangers are connected in parallel to the new supply pipe 20 and the new recovery pipe 21. In addition, the new water collection pipe 21 is connected to the water supply pipe 13 so that the tap water is circulated to the new supply pipe 20 through each heat exchanger 10, 11 is converted to hot water is converted to hot water. . Therefore, since hot water can be directly supplied from the new hot water supply pipe 22 without passing through the household heating heat exchanger 30 in each generation, hot water supply is faster than the indirect heating method using the conventional heat exchanger, and also used as hot water supply. Tap water is continuously replenished in the water supply pipe 13 as much as the quantity is heated in the heating heat exchanger 10 and the hot water supply heat exchanger 11 so that a hot water supply does not occur.

또한 신설공급관(20)과 신설회수관(21)은 층별로 직경이 동일하게 구성되기 때문에 각 세대에서 급탕으로 온수를 사용할 경우 신설회수관(21)에서 회수되는 온수량이 줄게 되는데, 이때 상기 상수도관(13)에서 수돗물이 보충되어 열교환기(10)(11)에서 열교환 된 온수가 신설공급관(20)으로 그만큼 충분히 보충되므로 4종관에서 2종관으로 교체하더라도 급탕 사용에 따른 난방수 공급에 차질이 발생되지 않는다. In addition, since the new supply pipe 20 and the new recovery pipe 21 are configured to have the same diameter for each floor, when the hot water is used as the hot water supply in each household, the amount of hot water recovered from the new recovery pipe 21 is reduced. Tap water is replenished in the pipe (13), so that the hot water heat exchanged in the heat exchanger (10) and (11) is sufficiently replenished with the new supply pipe (20). It does not occur.

또한 최상층의 경우 겨울철 난방밸브(32)의 최대 개방시 세대난방열교환기(30)로 흐르는 온수의 유속이 빨라져서 열교환효율이 저하된다. 이때 상기 제어부(14)는 자동밸브(24)를 최대 90%까지 닫아 리턴배관(23)으로 흐르는 난방수의 유속을 최대한 느리게 함으로써, 상기 최상층의 세대난방열교환기(30)로 순환되는 온수의 유속이 상대적으로 느려지게 한다. 즉 신설공급관(20)에서 최상층 세대난방열교환기(30)로 향하는 온수는 리턴배관(23)에서 신설회수관(21)으로 순환되는 온수와 합쳐지는데, 이때 리턴배관(23)에서 신설회수관(21) 쪽으로 순환되는 온수의 유속이 느려지므로 상기 난방밸브(32)를 최대로 개방시키더라도 신설회수관(21)에서 온수의 유속이 느려진 상태이므로 상기 세대난방열교환기(30)에서의 유속이 함께 느려져 충분한 열교환이 이뤄진다.In addition, in the case of the uppermost floor, the flow rate of the hot water flowing to the generation heating exchanger 30 at the maximum opening of the winter heating valve 32 is reduced, so that the heat exchange efficiency is lowered. At this time, the control unit 14 closes the automatic valve 24 up to 90% to slow the flow rate of the heating water flowing to the return pipe 23 as much as possible, so that the flow rate of the hot water circulated to the generation heating heat exchanger 30 of the uppermost layer is Relatively slow. In other words, the hot water from the new supply pipe (20) to the top floor heating radiator (30) is combined with the hot water circulated from the return pipe (23) to the new recovery pipe (21), where the new recovery pipe (21) in the return pipe (23) Since the flow rate of the hot water circulated toward) becomes slow, even if the heating valve 32 is opened to the maximum, the flow rate of the hot water in the new recovery pipe 21 is slowed down, so that the flow rate in the generation heating / heat exchanger 30 is slowed down together. Heat exchange takes place.

또한 환절기나 여름철에는 바닥난방 수요가 감소되므로 상기 제어부(14)에서 자동밸브(24)를 50% 정도 개방하여 온수의 흐름에 정체가 발생되지 않도록 함으로써 상기 신설공급관(20) 및 신설회수관(21)에 스케일이 발생되는 것을 막는다.In addition, since the demand for floor heating is reduced during the season or summer, the control unit 14 opens the automatic valve 24 by about 50% so that congestion does not occur in the flow of hot water. To prevent scale from occurring.

또한 각 층의 급탕은 상기 세대난방열교환기(30)를 거치지 않고 상기 신설공급관(20)에 직접 연결된 신설급탕관(22)을 통하여 이뤄진다. 따라서 상기 세대난방열교환기(30)를 거쳐 간접 열교환 하던 방식에 비하여 급탕이 신속하게 이뤄지므로 열손실이 적다. 상기 신설공급관(20) 및 신설급탕관(22)은 새로 배관된 것이므로 내부에 스케일이 발생되지 않아서 이들 배관으로 흐르는 온수를 급탕에 직접 이용하더라도 비위생적이지 않다.In addition, the hot water supply of each floor is made through the new hot water supply pipe 22 directly connected to the new supply pipe 20 without passing through the generation heating heat exchanger (30). Therefore, the hot water supply is faster than indirect heat exchange through the generation heating heat exchanger (30), so the heat loss is low. Since the new supply pipe 20 and the new hot water supply pipe 22 are newly piped, no scale is generated therein, so even if hot water flowing through these pipes is directly used for hot water supply, it is not unsanitary.

또한 저층에서 고층으로 갈수록 신설공급관(20) 및 신설회수관(21)의 직경이 점차 줄어들기 때문에 저층에서 급탕으로 온수가 사용되더라도 고층까지 온수가 충분히 공급되며, 사용 후 남은 온수가 신설회수관(21)으로 빠르게 순환되므로 정체가 발생되지 않아 2개의 배관으로 난방과 급탕이 부족하지 않는 이점이 있다.In addition, since the diameter of the new supply pipe 20 and the new recovery pipe 21 gradually decreases from the lower floor to the higher floor, even if hot water is used as the hot water supply in the lower floor, the hot water is sufficiently supplied to the high floor. 21) There is an advantage that the heating and hot water supply is not insufficient due to the two pipes because there is no congestion because it is rapidly circulated to 21).

In the case of central heating, an industrial boiler 40 is connected in series with two small capacity heat exchangers 41 and a large capacity heat exchanger 42. The small capacity heat exchanger 41 is a small capacity hot water tank 43 and a large capacity hot water tank ( 44) has the same configuration as the embodiment of the present invention except that it is connected in parallel to produce hot water.
