Description
본 발명은 공동주택의 온수공급 시스템에 관한 것으로서, 더욱 상세하게는 수돗물이 지열과 태양열을 거치면서 예열되고 또한 보일러의 연통을 거치면서 추가적으로 예열된 뒤 보일러에서 가열되도록 함으로써, 찬 수돗물을 직접 가열할 때 보다 열효율이 좋아지고 또한 지열과 태양열을 통하여 예열된 수돗물은 관리실이나 노인정 같은 다중이용시설의 팬코일유니트를 거치면서 난방열원으로 사용되게 하여 관리비를 절약할 수 있는 공동주택 온수공급 시스템에 관한 것이다.The present invention relates to a hot water supply system for an apartment complex. More specifically, the present invention relates to a system for directly heating cold tap water by preheating tap water through geothermal and solar heat and additionally preheating it through the flue of a boiler and then heating it in the boiler. It is about a hot water supply system for apartment complexes that has improved thermal efficiency and can save management costs by allowing tap water preheated through geothermal and solar power to be used as a heating heat source while passing through a fan coil unit in a multi-use facility such as a management office or senior citizen home. .
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-like apartment complexes use a central heating system for heating and hot water supply, which heats water in the machine room with a large industrial boiler and supplies heating water and hot water supply to each household through heating and hot water lines, respectively. In addition, when using district heating such as combined heat and power generation, the heating water and hot water supplied from the combined heat and power plant are supplied to each household from the machine room to provide heating and hot water.
중앙난방의 경우 수돗물이 기계실 보일러의 열교환기를 거치면서 가열된 뒤 축열조에 온수로 저장되고 각 세대에 온수관으로 공급된다. 이러한 수돗물은 지하 2M에 매립된 수도관에서 공급되기 때문에 사계절 5℃ ∼ 10℃도 정도의 온도를 유지하는데, 이러한 수돗물을 60℃ 이상으로 가열하기 위하여 보일러의 열원이 많이 필요하게 된다.In the case of central heating, tap water is heated as it passes through a heat exchanger in the machine room boiler, then stored as hot water in a heat storage tank and supplied through hot water pipes to each household. Since this tap water is supplied from a water pipe buried 2m underground, the temperature is maintained at around 5°C to 10°C throughout the year. In order to heat this tap water to 60°C or higher, a large amount of heat source from a boiler is required.
이를 감안하여 종래에는 수돗물을 태양열이나 지열로 예열한 뒤 보일러에 공급하는 기술들이 제안된 바 있다. 종래 특허 제1471557호는 태양열집열기에서 생산되는 온수를 저장하는 태양열 축열조와 보일러에서 생산되는 온수를 저장하는 보일러 축열조를 병렬로 연결하여 각 세대에 온수를 공급하는 기술이다.Considering this, technologies have been proposed in the past to preheat tap water with solar or geothermal heat and then supply it to the boiler. Previous patent No. 1471557 is a technology that supplies hot water to each household by connecting a solar thermal storage tank that stores hot water produced by a solar collector and a boiler thermal storage tank that stores hot water produced by a boiler in parallel.
그러나 상기 태양열집열기는 온수 생산에 한계가 있으며 또한 세대가 많을 경우 온수가 분산되기 때문에 태양열 축열조의 활용성이 떨어지는 문제가 있었다. 또한 찬 수돗물이 보일러 열교환기로 직접 투입되기 때문에 열효율이 떨어지는 등의 문제점이 있었다.However, the solar collector has limitations in producing hot water, and when there are many households, hot water is dispersed, which reduces the usability of the solar heat storage tank. In addition, there were problems such as low thermal efficiency because cold tap water was directly injected into the boiler heat exchanger.
종래 특허 제1168551호는 각 세대에 축열탱크를 구비하고 태양열집열기에 각 세대의 축열탱크를 가열하는 방식의 기술이다. 그러나 종래 특허는 태양열집열기의 열원이 각 세대의 축열탱크에 분산되므로 축열하는데 많은 시간이 소요되고 또한 날이 흐리거나 태양열원이 부족한 저녁시간대에는 사용이 불가능한 등의 문제점이 있었다.Previous patent No. 1168551 is a technology that equips each household with a heat storage tank and heats the heat storage tank of each household with a solar collector. However, the conventional patent had problems such as the fact that the heat source of the solar collector was distributed to the heat storage tank of each household, so it took a lot of time to store heat, and it could not be used in the evening when the day was cloudy or the solar power source was insufficient.
본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 수돗물이 지열과 태양열을 거치면서 예열되고 또한 보일러의 연통을 거치면서 추가적으로 예열된 뒤 보일러에서 가열되도록 함으로써, 찬 수돗물을 직접 가열할 때 보다 열효율이 좋아지고 또한 지열과 태양열을 통하여 예열된 수돗물은 관리실이나 노인정 같은 다중이용시설의 팬코일유니트를 거치면서 난방열원으로 사용되게 하여 관리비를 절약할 수 있는 공동주택 온수공급 시스템을 제공함에 있다.The present invention was developed in consideration of conventional problems, and the purpose of the present invention is to directly heat cold tap water by preheating tap water through geothermal and solar heat, and additionally preheating through the flue of the boiler and then heating it in the boiler. It provides a hot water supply system for apartment complexes that has improved thermal efficiency and saves management costs by allowing tap water preheated through geothermal and solar power to be used as a heating heat source while passing through the fan coil unit of multi-use facilities such as management offices or senior homes. It is in
이를 위하여 본 발명은 수돗물을 지열 및 태양열로 예열하여 축열조의 보조열원으로 사용하는 공동주택의 온수공급 시스템에 있어서, 상수도공급부와 삼방밸브로 연결되는 지열관 및 상기 지열관과 연결되는 태양열축열판이 구비되고; 상기 태양열축열판과 보조삼방밸브로 연결되는 팬코일유니트가 다중이용시설에 구비되며; 여름철에는 상수도공급부와 상기 팬코일유니트가 직접 연결되게 상기 삼방밸브를 조작하여 사계절 5℃ ∼ 10℃ 유지되는 수돗물로 상기 다중이용시설을 냉방하고, 상기 팬코일유니트로 향하는 수돗물 일부가 상기 태양열축열판에서 예열된 뒤 상기 팬코일유니트에서 나오는 수돗물과 합류되게 상기 보조삼방밸브를 조작하며; 겨울철에는 상수도공급부와 상기 지열관이 직접 연결되게 상기 삼방밸브를 조작하고, 상기 태양열축열판과 상기 팬코일유니트가 직접 연결되게 상기 보조삼방밸브를 조작하여서 수돗물이 상기 지열관 및 태양열축열판을 거치면서 예열된 상태로 상기 팬코일유니트를 거치면서 다중이용시설이 난방되도록 한 특징이 있다.To this end, the present invention is a hot water supply system for an apartment complex in which tap water is preheated with geothermal and solar heat and used as an auxiliary heat source for a heat storage tank, and is equipped with a geothermal heat pipe connected to a water supply unit and a three-way valve and a solar heat storage plate connected to the geothermal pipe. become; A fan coil unit connected to the solar heat storage plate and an auxiliary three-way valve is provided in the multi-use facility; In the summer, the three-way valve is operated so that the water supply unit and the fan coil unit are directly connected to cool the multi-use facility with tap water maintained at 5°C to 10°C in all seasons, and a portion of the tap water heading to the fan coil unit is transferred to the solar heat storage plate. After preheating, the auxiliary three-way valve is operated to merge with tap water coming from the fan coil unit; In winter, the three-way valve is operated so that the water supply unit and the geothermal heat pipe are directly connected, and the auxiliary three-way valve is operated so that the solar heat storage plate and the fan coil unit are directly connected, so that tap water passes through the geothermal heat pipe and the solar heat storage plate. It has the characteristic of heating the multi-use facility while passing through the fan coil unit in a preheated state.
본 발명에 따르면 수돗물이 지열과 태양열을 거치면서 예열되고 또한 보일러 연통의 열을 흡열하는 과정에서 추가적으로 예열된 뒤 보일러 열교환기에서 최종적으로 가열되도록 함으로써, 찬 수돗물이 보일러에 직접 투입될 때 보다 열효율이 향상되는 이점이 있다.According to the present invention, tap water is preheated through geothermal and solar heat, and is additionally preheated in the process of absorbing heat from the boiler flue and is finally heated in the boiler heat exchanger, thereby improving thermal efficiency compared to when cold tap water is directly injected into the boiler. There are benefits to improving it.
또한 상기 예열된 수돗물은 보일러로 공급되기 전에 관리실 또는 노인정 같은 다중이용시설의 팬코일유니트를 거치면서 집중 난방이 이뤄지도록 하기 때문에, 종래 예열된 수돗물을 각 세대의 난방열원으로 분산시키는 과정에서 난방온도가 낮아져 실질적인 난방이 이뤄지지 못하는 단점을 극복할 수 있다.In addition, since the preheated tap water is intensively heated by passing through a fan coil unit in a multi-use facility such as a management office or senior citizen center before being supplied to the boiler, the heating temperature is increased in the process of dispersing the conventionally preheated tap water to the heating heat source of each household. It is possible to overcome the disadvantage of not being able to achieve actual heating due to the low temperature.
또한 축열조에 전기히터를 설치하여 태양전지로 온수를 가열하기 때문에 온수를 사용하지 않는 새벽시간 동안 온수온도를 지속적으로 유지할 수 있으므로 보일러의 가동시간을 줄일 수 있는 등의 이점이 있다.In addition, since an electric heater is installed in the heat storage tank to heat the hot water with solar cells, the hot water temperature can be continuously maintained during the early morning hours when hot water is not used, which has the advantage of reducing boiler operation time.
도 1은 본 발명 한 실시예의 온수공급 시스템의 개념도1 is a conceptual diagram of a hot water supply system according to an embodiment of the present invention.
본 발명 한 실시예의 온수공급 시스템은 중앙난방식에 적용되는 것으로서, 기계실에는 10ton 정도의 축열조(12)와 보일러(10)가 열교환기(11)를 통하여 서로 연결되고, 30ton 정도의 보조축열조(12a)와 보조보일러(10a)가 보조열교환기(11a)를 통하여 서로 연결된 상태로 구비된다. 그리고 축열조(12)와 보조축열조(12a)는 각 세대의 세대열교환기(80)와 공급관(15)으로 병렬 연결되고, 각 세대열교환기(80)는 회수관(16)을 통하여 축열조(12) 및 보조축열조(12a)와 연결된다.The hot water supply system of one embodiment of the present invention is applied to a central heating system. In the machine room, a heat storage tank (12) of about 10 tons and a boiler (10) are connected to each other through a heat exchanger (11), and an auxiliary heat storage tank (12a) of about 30 tons is installed. ) and the auxiliary boiler (10a) are connected to each other through the auxiliary heat exchanger (11a). And the heat storage tank (12) and the auxiliary heat storage tank (12a) are connected in parallel to the household heat exchanger (80) and the supply pipe (15) of each household, and each household heat exchanger (80) is connected to the heat storage tank (12) through the return pipe (16). and is connected to the auxiliary heat storage tank (12a).
상수도의 수돗물은 상기 열교환기(11)와 보조열교환기(11a)에서 가열된 뒤 상기 축열조(12) 및 보조축열조(12a)에 저장되는데, 본 발명 한 실시예는 수돗물이 지열 및 태양열을 통하여 예열된 상태에서 상기 열교환기(11) 및 보조열교환기(11a)로 공급된다.Tap water from the water supply is heated in the heat exchanger 11 and the auxiliary heat exchanger 11a and then stored in the heat storage tank 12 and the auxiliary heat storage tank 12a. In one embodiment of the present invention, tap water is preheated through geothermal heat and solar heat. In this state, it is supplied to the heat exchanger (11) and the auxiliary heat exchanger (11a).
이를 위하여 본 발명 한 실시예는 겨울철 기계실의 상수도공급부(30)는 삼방밸브(40)의 한쪽 출구를 통하여 지하에 매립되는 지열관(50)과 연결되고, 지열관(50)은 지상의 태양열축열판(60)과 연결된다. 그리고 태양열축열판(60)은 보조삼방밸브(41)를 통하여 관리실 또는 노인정 같은 다중이용시설(20)의 팬코일유니트(21)로 연결되어 예열된 수돗물이 난방에 사용되도록 하며, 상기 보일러(10)의 배기가스가 배출되는 연통(13) 외주연에 코일관(61)이 감긴 상태로 구비되고, 상기 보조보일러(10a)의 배기가스가 배출되는 보조연통(13a) 외주연에 보조코일관(61a)이 감긴상태로 구비된다.For this purpose, in one embodiment of the present invention, the water supply unit 30 of the machine room in winter is connected to the geothermal pipe 50 buried underground through one outlet of the three-way valve 40, and the geothermal pipe 50 is connected to solar heat storage on the ground. It is connected to the plate (60). And the solar heat storage plate 60 is connected to the fan coil unit 21 of the multi-use facility 20, such as a management office or senior citizen center, through the auxiliary three-way valve 41 to allow preheated tap water to be used for heating, and the boiler 10 ) is provided with a coil pipe (61) wound around the outer periphery of the flue (13) through which the exhaust gas of the auxiliary boiler (10a) is discharged, and an auxiliary coil pipe ( 61a) is provided in a wound state.
그리고 상기 팬코일유니트(21)와 상기 코일관(61) 및 보조코일관(61a)이 배관으로 연결된 상태에서 상기 코일관(61)이 열교환기(11)와 연결되고, 상기 보조코일관(61a)이 보조열교환기(11a)와 연결된다.And while the fan coil unit 21, the coil tube 61, and the auxiliary coil tube 61a are connected by a pipe, the coil tube 61 is connected to the heat exchanger 11, and the auxiliary coil tube 61a ) is connected to the auxiliary heat exchanger (11a).
또한 여름철 상기 삼방밸브(40)의 다른쪽 출구는 상기 팬코일유니트(21) 및 상기 태양열축열판(60)에 각각 연결된다. 따라서 수돗물이 팬코일유니트(21)로 직접 향하기 때문에 상기 지열관(50) 및 태양열축열판(60)에서 예열되지 않으므로 찬 수돗물로 다중이용시설(20)을 냉방할 수 있다. 그리고 수돗물 일부가 상기 팬코일유니트(21)로 향하지 않고 상기 태양열축열판(60)으로 향하여 예열되는데, 이때 상기 보조삼방밸브(41)에 의해 상기 태양열축열판(60)이 코일관(61)과 연결되기 때문에 상기 팬코일유니트(21)에서 나오는 수돗물과 합류되어서 상기 코일관(61) 및 보조코일관(61a)으로 향한다.Also, in summer, the other outlet of the three-way valve 40 is connected to the fan coil unit 21 and the solar heat storage plate 60, respectively. Therefore, since the tap water is directed to the fan coil unit 21 and is not preheated in the geothermal pipe 50 and the solar heat storage plate 60, the multi-use facility 20 can be cooled with cold tap water. And some of the tap water is not directed to the fan coil unit 21 but is preheated toward the solar heat storage plate 60. At this time, the solar heat storage plate 60 is connected to the coil pipe 61 by the auxiliary three-way valve 41. Because it is connected, it joins the tap water coming out of the fan coil unit 21 and heads to the coil pipe 61 and the auxiliary coil pipe 61a.
