Description

난방관을 이용한 세대 급탕 공급시스템 {Home hot water supply system using heating pipes}Home hot water supply system using heating pipes}

본 발명은 난방관을 이용한 세대 급탕 공급시스템에 관한 것으로, 특히 기존에 급수관을 통해 급수하고, 2개(공급과 환수)의 난방관과 2개(공급과 환수)의 급탕관을 분리하여 아파트 등의 각 세대내의 급탕과 난방을 수행하였던 것을 개선하여 급탕관은 모두 제거하고, 1개의 급수관과 2개의 난방관만 사용하여 각 세대에 난방과 급탕이 이루어지도록 함은 물론, 공급과 환수의 온도차를 크게 하여 유량을 적게하므로 동력비를 줄임과 동시에 공사비용을 절감할 수 있도록 한 것이다.The present invention relates to a household hot water supply system using a heating pipe, and in particular, water is supplied through a conventional water supply pipe, and two (supply and return) heating pipes and two (supply and return) hot water pipes are separated to provide an apartment, etc. By improving the hot water supply and heating within each household, all hot water supply pipes were removed, and only one water supply pipe and two heating pipes were used to provide heating and hot water supply to each household, as well as to reduce the temperature difference between supply and return water. It is made larger to reduce the flow rate, so that power costs and construction costs can be reduced at the same time.

일반적으로 지역난방 시스템은 집단에너지를 공급하는 사업자가 다수의 개별 사용자에게 난방 및 급탕을 공급하기 위해 지역난방 열원배관을 통해 집단에너지를 공급하는 시스템으로 개별적으로 사용자가 난방설비를 갖추는 개별난방 시스템과는 차이가 있다.In general, a district heating system is a system in which a business operator supplying collective energy supplies collective energy through district heating heat source pipes to supply heating and domestic hot water to a number of individual users. has a difference.

즉, 지역난방은 한 개의 도시 또는 일정한 지역 내에 있는 주택, 상가, 사무실, 학교, 병원, 공장 등 각종 건물이 개별적으로 난방설비를 갖추지 않고, 대규모 열생산시설, 즉 열병합발전소를 건설하여 열수송관에 흐르는 중온수(80~120℃)를 열 수요처에 설치되는 열교환기를 통하여 난방 및 급탕에 필요한 저온수(70~30℃)를 생산, 단지내 난방관과 급탕관을 통하여 각 세대나 사용처에 공급하는 시스템으로 집단에너지 공급방식중 하나이다.In other words, in district heating, various buildings such as houses, shopping malls, offices, schools, hospitals, factories, etc. in a city or a certain area do not have individual heating facilities, and large-scale heat production facilities, that is, combined heat and power plants, are built and A system that produces low-temperature water (70-30℃) required for heating and hot water supply through a heat exchanger installed in a heat demand place from flowing medium-temperature water (80~120℃), and supplies it to each household or user through heating and domestic hot water pipes in the complex. It is one of the collective energy supply methods.

이러한 종래의 지역난방 시스템의 열병합발전소는 보일러, 폐열보일러와, 증기터빈 발전기, 축열조와, 열교환기 및 순환펌프로 이루어지고, 상기 순환펌프에는 열공급 대상지역까지 열을 수송 및 회수하는 열수송관과, 사용자 열교환기가 연결되며 열수송관은 공급관과 환수관으로 이루어진다.The cogeneration plant of such a conventional district heating system is composed of a boiler, a waste heat boiler, a steam turbine generator, a heat storage tank, a heat exchanger, and a circulation pump. The user heat exchanger is connected, and the heat transport pipe consists of a supply pipe and a return pipe.

따라서, 종래의 지역난방 시스템은 보일러나 폐열보일러 등에서 발생되는 증기를 이용하여 증기터빈 발전기를 가동하고, 증기터빈 발전기에서 발생되는 폐열을 이용하여 중온수를 생산하며, 그 지역의 건물이나 아파트 등에 중온수를 공급하는 것으로, 건물이나 아파트 등에 공급된 중온수를 각 세대나 사용처에 난방이나 급탕열원으로 사용한다.Therefore, the conventional district heating system operates a steam turbine generator using steam generated from a boiler or a waste heat boiler, and produces medium hot water using waste heat generated from the steam turbine generator, and produces medium temperature water in buildings or apartments in the area. As water supply, medium-temperature water supplied to buildings or apartments is used as a heat source for heating or domestic hot water in each household or place of use.

종래에는 열병합발전소로부터 생산되는 열원 공급량이 부족하거나 초과될 경우 열병합발전소 설치시 계획된 규모 이상의 추가된 다른 세대나 사용처에 난방이나 급탕 열원을 공급하기 위하여 별도의 열병합발전소를 설립하거나 추가로 증설해야 하는 등의 설치비용이 과다하게 소요되는 문제가 있다.Conventionally, if the supply of heat source produced from the cogeneration plant is insufficient or exceeded, a separate cogeneration plant must be established or additionally expanded to supply heating or domestic hot water heat sources to other households or users that are added beyond the planned size when installing the cogeneration plant. There is a problem of excessive installation cost.

종래에는 도 1과 같이 아파트 등의 각 세대에 급탕과 난방을 공급하기 위하여 열생산시설(1)로부터 열교환기(4)를 설치하여 2개(공급과 환수)의 난방관(5)과 급탕 예열 열교환기(8) 및 급탕 재열 열교환기(9)를 설치하여 2개(공급과 환수)의 급탕관(15)을 분리 설치하여 세대내의 급탕과 난방이 이루어지도록 함과 함께 별도의 급수관(6)을 통해 급수가 이루어지도록 하고 있다.Conventionally, as shown in FIG. 1, in order to supply hot water and heating to each household such as an apartment, a heat exchanger 4 is installed from a heat production facility 1, and two (supply and return) heating pipes 5 and hot water preheating By installing a heat exchanger (8) and a hot water reheat heat exchanger (9), two (supply and return) hot water supply pipes (15) are installed separately to ensure that hot water supply and heating within the household are performed, as well as a separate water supply pipe (6) Water supply is provided through

즉, 종래에는 급수관(6)과 급탕관(15)에 세대급수관, 세대급탕관(15)을 연결하여 세대내에서 급수, 급탕이 공급되도록 함과 함께 난방관(5)을 통하여 세대내에 난방이 수행되도록 하였다.That is, in the prior art, household water supply pipes and household hot water pipes 15 are connected to the water supply pipe 6 and the hot water supply pipe 15 so that water supply and hot water are supplied within the household, and heating is performed within the household through the heating pipe 5. was made to be performed.

따라서, 종래에는 각 세대에 급탕과 난방을 수행하기 위하여 반드시 2개의 난방관(5)과 2개의 급탕관(15)을 분리설치하므로 설치비용이 증가함은 물론, 열손실이 많이 발생되는 문제점이 있었다.Therefore, in the prior art, since the two heating pipes 5 and the two hot water pipes 15 are necessarily separately installed to perform hot water and heating in each household, installation costs increase and a lot of heat loss occurs. there was.

이하, 본 발명의 실시 예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 난방관을 이용한 세대 급탕 공급시스템을 나타낸 도면으로, 대규모 열생산시설(1), 즉 열병합발전소를 건설하여 열수송관(2,3)에 흐르는 중온수(80 ~ 120℃)를 열 수요처에 설치되는 열교환기(4)를 통하여 난방 및 급탕에 필요한 저온수(30 ~ 70℃)를 생산하여 각 세대에 난방을 공급하는 단지내 난방관(5)과, 급수펌프(11)로부터의 물을 급수하는 급수관(6)과, 상기 급수관(6)과 난방관(5)사이에 설치되어 난방관(5)의 열을 급수관(6)의 물쪽으로 전달하는 급탕 예열열교환기(8)와, 상기 예열 열교환기(8)에 연결되어 예열 열교환기(8)의 열량으로 물을 가열하여 열량이 커지도록 하는 재열 열교환기(9)와, 상기 재열열교환기(9)에 연결되어 온수를 공급하기 위한 세대온수관(7)와, 상기 급수관(6)에 연결되어 물을 공급하기 위한 세대급수관(6a)을 포함하여 구성된 것으로, 도면중 미설명부호 10은 세대난방배관이다.Figure 2 is a diagram showing a household hot water supply system using a heating pipe of the present invention, a large-scale heat production facility (1), that is, a cogeneration plant constructed and medium-temperature water (80 ~ 120 ° C) flowing through heat transport pipes (2, 3) from the heating pipe (5) and water pump (11) in the complex that supplies heating to each household by producing low-temperature water (30 ~ 70 ℃) required for heating and hot water supply through the heat exchanger (4) installed at the heat demand place. A water supply pipe (6) for supplying water, and a hot water preheating exchanger (8) installed between the water supply pipe (6) and the heating pipe (5) to transfer the heat of the heating pipe (5) to the water side of the water supply pipe (6) And, a reheat heat exchanger 9 connected to the preheat heat exchanger 8 to heat water with the heat of the preheat heat exchanger 8 so that the heat amount increases, and connected to the reheat heat exchanger 9 to supply hot water It is configured to include a household hot water pipe 7 for supply and a household water supply pipe 6a for supplying water by being connected to the water supply pipe 6, and reference numeral 10 in the drawing is a household heating pipe.

또한, 아파트 단위별로 열병합 발전기(13)를 설치하여 이러한 열병합 발전기(13)로부터 난방관(5)을 통해 각 세대에 난방을 공급할 수 있도록 구성할 수도 있다.In addition, a cogeneration generator 13 may be installed for each apartment unit so that heating may be supplied to each household from the cogeneration generator 13 through the heating pipe 5.

즉, 지역난방을 공급받아 난방을 공급하는 열교환기(4) 또는 열병합 발전기(13)와 연결된 난방관(5)을 통하여 각 세대에서 난방을 수행할 수 있다. That is, heating can be performed in each household through the heat exchanger 4 that receives district heating and supplies heating or the heating pipe 5 connected to the cogeneration generator 13.

또한, 각 세대급수관(6a)을 통하여는 별도의 급수관(6)을 통하여 급수가 이루어지므로 물을 공급받아 사용할 수 있다.In addition, since water is supplied through a separate water supply pipe 6 through each household water supply pipe 6a, water can be supplied and used.

한편, 본 발명에서는 기존의 급탕관을 사용하지 않는 대신 각 세대에서 급탕 기능을 난방을 이용하여 함께 수행하도록 한 것으로, 상기 급수관(6)과 난방관(5)사이의 각 세대내에, 급탕용 예열 열교환기(8)와 재열 열교환기(9)를 설치하여 급수관(6)을 통하여 공급되는 물이 이들 열교환기(8,9)를 통해 뜨겁게 데워진 상태에서 공급되도록 함으로써 각 세대의 급탕용 배관을 통해 바로 더운 물을 사용할 수 있다.On the other hand, in the present invention, instead of using the existing hot water pipe, each household performs the hot water supply function using heating, and within each household between the water supply pipe 6 and the heating pipe 5, preheating for hot water supply By installing the heat exchanger (8) and the reheating heat exchanger (9), the water supplied through the water supply pipe (6) is supplied in a heated state through these heat exchangers (8, 9) through the hot water supply pipe of each household. You can use hot water right away.

예를 들어, 상기 재열 열교환기(9)에는, 열량이 60도인 난방관(5)의 난방수를 통해 급탕 35도의 물을 55도로 가열하여 사용하며, 난방수는 재열열교환기(9)를 지나면서 38도로 떨어지게 된다.For example, in the reheat heat exchanger (9), water at a temperature of 35 degrees is heated to 55 degrees through heating water of a heating pipe (5) having a calorific value of 60 degrees, and the heating water passes through the reheat heat exchanger (9). and fall at 38 degrees.

그러면, 상기와 같이 열량이 38도로 떨어진 물을 예열 열교환기(8)로 보내어열량이 15도인 물을 30도로 가열시킴으로써 결국 예열 열교환기(8)로부터 환수되는 물의 온도는 30도가 된다.Then, as described above, the water having a calorific value of 38°C is sent to the preheating heat exchanger 8 to heat the water having a calorific value of 15°C to 30°C, so that the temperature of the water returned from the preheating heat exchanger 8 becomes 30°C.

따라서, 세대에 공급되는 난방온도 60도는 온수분배기와 재열열교환기(9)를 지나면서 38도, 예열열교환기(8)를 지나면서 30도로 온도차가 30도로 커지므로 유량이 줄어들어 동력비가 줄므로 공사비가 적게 든다.Therefore, the heating temperature supplied to the household is 38 degrees while passing through the hot water distributor and the reheat heat exchanger (9) and 30 degrees while passing through the preheat heat exchanger (8). costs less

본 발명은 열을 옮기는 것이지 물을 옮기는 목적은 아니므로 예열해서 환수되는 물의 온도를 이용하되, 한번 더 가열하여 환수온도를 더 떨어뜨려 보내는 것으로, 예컨대, 통상적으로 열량이 60도인 물을 45도로 환수하지만, 본 발명에서는 45도 물을 이용하여 30도로 환수온도를 더 떨어뜨려 보낸다.Since the purpose of the present invention is to transfer heat, not to transfer water, the temperature of the water returned after being preheated is used, but heated once more to further drop the return temperature. However, in the present invention, the water return temperature is further dropped to 30 degrees using 45 degrees water.

즉, 급수관(6)을 통하여 공급되는 물을 그대로 세대급수관(6a)을 통해 통상적으로 사용할 수 있고, 급수관(6)을 통하여 공급되는 물을 열교환기(8,9)를 거치도록 하여 물이 급탕으로 데워진 상태에서 세대온수관(7)을 통해 더운물로 사용할 수 있다.That is, the water supplied through the water supply pipe 6 can be used normally through the household water supply pipe 6a as it is, and the water supplied through the water supply pipe 6 passes through the heat exchangers 8 and 9 so that the water is supplied It can be used as hot water through the household hot water pipe (7) in a heated state.

상기와 같은 본 발명은 난방관(5)만으로도 각 세대에 난방을 제공함은 물론 열교환기(8,9)를 통해 급탕으로도 사용하도록 함으로써 기존의 급탕설비가 필요없어져 대폭적인 설치비용 절감과 열손실의 감소로 효율적인 열관리를 수행할 수 있다.The present invention as described above not only provides heating to each household with only the heating pipe (5), but also uses it as hot water through the heat exchangers (8, 9), eliminating the need for existing hot water supply facilities, thereby significantly reducing installation costs and heat loss. With the reduction of , it is possible to perform efficient thermal management.

상술한 바와 같은 본 발명은 상기 실시예에 국한되는 것은 아니고, 본 발명이 속하는 기술분야에서 다양한 변형에 의해 사용될 수 있음은 물론이다.The present invention as described above is not limited to the above embodiment, and can be used by various modifications in the technical field to which the present invention belongs, of course.
