본 발명은 태양열을 이용하여 급탕 공급 및 냉난방을 수행할 수 있도록 하는 태양열 급탕 및 냉난방 시스템에 관한 것이다.The present invention relates to a solar thermal hot water supply and heating/cooling system capable of performing hot water supply and heating/cooling using solar heat.

현재 화석연료의 고갈 등으로 대체 에너지의 개발이 진행되고 있고, 이에 따라 태양열을 이용하여 발전 및 실내 공기조화에 이용하는 기술이 많이 보급되고 있는 실정이다.Currently, development of alternative energy is in progress due to the depletion of fossil fuels and the like, and accordingly, technologies used for power generation and indoor air conditioning using solar heat are widely distributed.

도 1은 종래 기술에 따른 태양열을 이용하여 냉난방을 수행하는 태양열 급탕 및 냉난방 시스템의 구성도이다.1 is a block diagram of a solar thermal hot water supply and heating/cooling system that performs heating and cooling using solar heat according to the prior art.

종래 기술에 따른 냉난방 시스템은 태양열을 집열하여 열매체를 축열시키는 태양열 집열판(100)과, 태양열에 의해 축열된 열매체와 열교환하여 축열되는 축열탱크(110)와, 축열탱크(110)에 저장된 열수와 열교환하여 냉난방을 수행하는 냉난방 시스템(120)과, 축열탱크(110)에 저장된 열수와 열교환하여 온수를 공급하는 급탕 시스템(150)을 포함한다.The heating/cooling system according to the prior art includes a solar heat collecting plate 100 that collects solar heat and stores heat medium, a heat storage tank 110 that heats up by heat exchange with a heat medium stored by solar heat, and heat exchange with hot water stored in the heat storage tank 110 and a heating and cooling system 120 for performing heating and cooling, and a hot water supply system 150 for supplying hot water by exchanging heat with hot water stored in the thermal storage tank 110 .

태양열 집열판(100)은 열매체가 순환되는 열매체 순환라인(102)과 연결되고, 이 열매체 순환라인(102)에는 부족한 열매체를 공급해주는 열매체 탱크(104)와 온도변화에 따라 수축 및 팽창되는 열매체의 체적변화를 흡수하는 팽창탱크(106)가 설치된다.The solar heat collecting plate 100 is connected to a heat medium circulation line 102 through which a heat medium is circulated, and the heat medium tank 104 for supplying insufficient heat medium to the heat medium circulation line 102 and the volume of the heat medium contracted and expanded according to the temperature change An expansion tank 106 to absorb changes is installed.

열매체 순환라인(102)에는 태양열 열교환기(112)가 설치되고, 이 태양열 열교환기(112)는 축열탱크(110)와 축열라인(114)에 의해 연결된다.A solar heat exchanger 112 is installed in the heat medium circulation line 102 , and the solar heat exchanger 112 is connected to the heat storage tank 110 and the heat storage line 114 .

냉난방 시스템은 축열탱크(110)와 제1 및 제2열수라인(122,124)에 의해 연결되어 축열탱크(110)의 열수와 열교환되는 흡수식 냉난방기(126)와, 이 흡수식 냉난방기(126)에 필요한 냉수를 공급하는 냉수탱크(128)와, 흡수식 냉난방기(126)와 연결되는 실외 열교환기(130)와, 흡수식 냉난방기(126)에서 냉각된 냉수 또는 가열된 온수가 공급되어 실내 냉난방 작용을 수행하는 실내 공조기(132)로 구성된다.The heating/cooling system is connected to the heat storage tank 110 and the first and second hot water lines 122 and 124 to heat-exchange with the hot water of the heat storage tank 110 and the absorption type air conditioner 126, and the cooling water required for the absorption type air conditioner 126. An indoor air conditioner ( 132).

그리고 냉난방 시스템(120)에는 축열탱크(110)의 온도가 설정온도 이하일 경우 축열탱크와 흡수식 냉난방기(126) 사이를 차단한 후 흡수식 냉난방기(126)에 필요한 열원을 공급하는 보일러(134)와 보일러 탱크(136)가 구비된다.In addition, in the heating and cooling system 120, when the temperature of the thermal storage tank 110 is below the set temperature, the boiler 134 and the boiler tank for supplying a heat source required to the absorption type heating and cooling unit 126 after blocking between the thermal storage tank and the absorption type air conditioner 126 (136) is provided.

급탕 시스템(150)은 온수를 공급하는 급탕탱크(154)와, 이 급탕탱크에 저장된 물과 축열탱크(110)에 저장된 열수 사이를 열교환시키는 급탕 열교환기(152)로 구성된다.The hot water supply system 150 includes a hot water supply tank 154 for supplying hot water, and a hot water supply heat exchanger 152 for exchanging heat between the water stored in the hot water supply tank and the hot water stored in the heat storage tank 110 .

이와 같이 구성되는 종래 기술에 따른 태양열 급탕 및 냉난방 시스템의 작용을 살펴보면, 축열탱크(110)의 온도가 낮아 흡수식 냉난방기(126)를 가동하기에 충분한 온도에 도달되지 못할 경우 보일러(134)가 작동되어 보일러 탱크(136) 내에 저장된 물을 가열하고 이 가열된 열수가 흡수식 냉난방기(126)의 열원으로 사용된다. 이때, 축열탱크(110)와 흡수식 냉난방기(126) 사이는 차단되고 축열탱크(110)는 계속 태양열 집열판(100)에 의한 축열을 실시한다.Looking at the action of the solar hot water supply and heating and cooling system according to the prior art configured as described above, when the temperature of the thermal storage tank 110 is low and does not reach a temperature sufficient to operate the absorption type air conditioner 126, the boiler 134 is operated, The water stored in the boiler tank 136 is heated, and the heated hot water is used as a heat source of the absorption type air conditioner 126 . At this time, the space between the heat storage tank 110 and the absorption type air conditioner 126 is blocked, and the heat storage tank 110 continues to perform heat storage by the solar heat collecting plate 100 .

그리고, 축열탱크(110)의 온도가 설정온도에 도달되면 보일러(134)가 정지되고 축열탱크(110)와 흡수식 냉난방기(126)가 연통되어 축열탱크(110)의 열수가 흡수식 냉난방기(126)로 공급된다.And, when the temperature of the heat storage tank 110 reaches the set temperature, the boiler 134 is stopped and the heat storage tank 110 and the absorption type air conditioner 126 communicate with each other, so that the hot water from the heat storage tank 110 is transferred to the absorption type air conditioner 126 . is supplied

하지만, 종래 기술에 따른 태양열 급탕 및 냉난방 시스템은 일광량이 부족하여 축열탱크의 온도가 설정온도(약 90℃) 이하일 경우 태양열 집열장치에서 획득한 태양열을 활용하지 못하고 계속해서 축열을 실시해야되며, 이때 축열되는 시간이 경과하면 할수록 실질적으로 냉난방에 사용되지 못하고 또한, 주위로 방열되는 열량이 증가하게 되므로 원하는 온도에 도달되는 시간이 더 소요되어 효율이 떨어지는 문제점이 있다.However, in the solar hot water supply and heating/cooling system according to the prior art, when the temperature of the thermal storage tank is below the set temperature (about 90 ° C) due to insufficient sunlight, the solar heat obtained from the solar thermal collector cannot be utilized and the heat storage must be continued. In this case, as the amount of time for heat storage elapses, it is not substantially used for heating and cooling, and the amount of heat radiated to the surroundings increases.

그리고, 축열탱크의 온도가 설정온도보다 낮아 흡수식 냉난방기를 가동하기에 충분한 온도에 도달되지 못할 경우 축열탱크와 흡수식 냉난방기 사이를 차단한 후 보일러를 작동시켜 흡수식 냉난방기에 필요한 열량을 공급해야되므로 에너지 효율이 현저하게 떨어지는 문제점이 있다.In addition, if the temperature of the heat storage tank is lower than the set temperature and the temperature sufficient to operate the absorption type air conditioner cannot be reached, the energy efficiency is reduced because the heat quantity required for the absorption type air conditioner must be supplied by operating the boiler after shutting off the between the heat storage tank and the absorption type air conditioner. There is a problem that it falls significantly.

본 발명의 목적은 태양열을 이용하여 급탕 공급 및 냉난방을 수행할 수 있는 태양열 급탕 및 냉난방 시스템을 제공하는 것이다.It is an object of the present invention to provide a solar thermal hot water supply and heating/cooling system capable of performing hot water supply and heating/cooling using solar heat.

상기한 구성에 따르면, 본 발명의 태양열 급탕 및 냉난방 시스템은 흡수식 냉난방기로 직접 열원을 공급하는 보일러와, 축열탱크의 온도가 설정온도 이하이면 열원을 발생시키는 보조열원 발생부를 구비하여 태양열 에너지가 충분치 못하여 축열탱크의 온도가 설정온도 이하로 내려가면, 보조열원 공급부가 작동되어 보조열원과 축열탱크에 저장된 열수가 보조열원 열교환기에서 열교환되어 축열탱크의 부족한 열량을 보충함으로써, 에너지 효율을 극대화할 수 있는 장점이 있다. According to the above configuration, the solar hot water supply and heating/cooling system of the present invention includes a boiler that directly supplies a heat source to an absorption type air conditioner, and an auxiliary heat source generator that generates a heat source when the temperature of the heat storage tank is below the set temperature.

급탕탱크(254)는 온수 파이프(260)에 의해 온수를 공급하고, 급수 파이프(262)를 통해 부족한 물을 공급받는다.The hot water supply tank 254 supplies hot water through the hot water pipe 260 and receives insufficient water through the water supply pipe 262 .

보조열원 시스템(270)은 일광량이 부족하여 축열탱크(210)의 온도가 설정온도(약 90℃)보다 낮을 경우 작동되어 축열탱크(210)의 부족한 열량을 보충해주는 역할을 한다. 이러한 보조열원 시스템(270)은 축열탱크(210)에 필요한 보조열원을 발생시키는 보조열원 발생부(272)와, 이 보조열원 발생부(272)와 축열탱크(210) 사이에 설치되어 축열탱크(210)와 보조열원 발생부(272) 사이를 열교환시키는 보조열원 열교환기(274)로 구성된다.The auxiliary heat source system 270 is operated when the temperature of the thermal storage tank 210 is lower than the set temperature (about 90° C.) due to insufficient sunlight, and serves to supplement the insufficient amount of heat in the thermal storage tank 210 . This auxiliary heat source system 270 is installed between the auxiliary heat source generator 272 for generating an auxiliary heat source required for the heat storage tank 210, and the auxiliary heat source generator 272 and the heat storage tank 210, the heat storage tank ( 210) and an auxiliary heat source heat exchanger 274 for exchanging heat between the auxiliary heat source generating unit 272.

보조열원 열교환기(274)는 제3열수라인(280)에 의해 축열탱크(210)와 연결되고 제1열수라인(230)에 의해 흡수식 냉난방기(222)와 연결되어 축열탱크(210)의 열수가 순환될 수 있도록 하고, 보조열원 라인(288)이 연결되어 보조열원 발생부(272)에서 발생되는 보조열원이 순환될 수 있도록 한다. 따라서, 보조열원 열교환기(274)에서 축열탱크(210)의 열수와 보조열원 발생부(272)의 보조열원이 열교환된다.The auxiliary heat source heat exchanger 274 is connected to the heat storage tank 210 by the third hot water line 280 and is connected to the absorption type air conditioner 222 by the first hot water line 230 so that the hot water of the heat storage tank 210 is The auxiliary heat source line 288 is connected so that the auxiliary heat source generated by the auxiliary heat source generating unit 272 can be circulated. Accordingly, in the auxiliary heat source heat exchanger 274 , the hot water of the heat storage tank 210 and the auxiliary heat source of the auxiliary heat source generating unit 272 exchange heat.

제3열수라인(280)과 제1열수라인(230)은 제4 연결라인(284)으로 연결되며, 제3열수라인(280)과 제4 연결라인(284)이 만나는 지점에는 3방향 밸브(286)가 설치된다. 이 3방향 밸브(286)는 제3열수라인(280)과 제4 연결라인(284)을 연통시켜 축열탱크(210)의 열수가 보조열원 열교환기(274)를 거치지 않고 바로 제1열수라인(230)을 통해 흡수식 냉난방기(222)로 공급되도록 하거나, 제3열수라인(280)을 보조열원 열교환기(274)와 연통시켜 축열탱크(210)의 열수가 보조열원 열교환기(274)를 통과한 후 흡수식 냉난방기(222)로 공급될 수 있도록 한다.The third hot water line 280 and the first hot water line 230 are connected by a fourth connecting line 284, and at the point where the third hot water line 280 and the fourth connecting line 284 meet, a three-way valve ( 286) is installed. The three-way valve 286 communicates the third hot water line 280 and the fourth connection line 284, so that the hot water of the heat storage tank 210 does not go through the auxiliary heat source heat exchanger 274, but directly into the first hot water line ( 230) to be supplied to the absorption type air conditioner 222, or the third hot water line 280 is communicated with the auxiliary heat source heat exchanger 274 so that the hot water of the heat storage tank 210 has passed through the auxiliary heat source heat exchanger 274.

이와 같이 구성되는 본 발명의 일 실시예에 따른 태양열 급탕 및 냉난방 시스템의 작용을 다음에서 설명한다.The operation of the solar thermal hot water supply and heating/cooling system according to an embodiment of the present invention configured in this way will be described below.

먼저, 태양열 에너지가 충분할 경우 태양열을 태양열 집열판(200)에서 집열하여 열매체를 축열시키고, 태양열 열교환기(214)에서 열매체와 축열탱크(210)의 열수가 열교환된다. 이때, 3방향 밸브(286)는 축열탱크(210)와 제4 연결라인(284)을 연통시켜 축열탱크(210)와 흡수식 냉난방기(222)를 연결한다. 그러면 축열탱크(210)의 열수가 흡수식 냉난방기(222)로 공급되어 흡수식 냉난방기(222)에서 열수와 열효교환하여 실내 공조기(228)로 냉난방을 위한 냉수를 공급하고, 실내 공조기(228)에서 실내 냉난방을 수행한다.First, when the solar thermal energy is sufficient, the solar heat is collected by the solar heat collecting plate 200 to store heat medium, and the heat medium and the hot water of the heat storage tank 210 exchange heat in the solar heat exchanger 214 . At this time, the three-way valve 286 connects the heat storage tank 210 and the absorption type air conditioner 222 by communicating the heat storage tank 210 and the fourth connection line 284 .

그리고, 온수를 공급하자 할 경우 축열탱크(210)의 열수와 급탕탱크(254)의 급수가 급탕 열교환기(252)에서 열교환되어 급탕탱크(254)에 저장된 급수를 데워 온수를 공급한다.And, when hot water is to be supplied, the hot water of the heat storage tank 210 and the water supplied from the hot water supply tank 254 are heat exchanged in the hot water heat exchanger 252 to heat the water stored in the hot water supply tank 254 to supply hot water.

이와 같은 날씨가 흐리거나 비가 오거나 하여 태양열 에너지가 충분하지 못하여 축열탱크(210)의 축열이 설정온도에 도달하지 못하면 보조열원을 이용하여 축열탱크(210)에 부족한 열원을 공급한다. 즉, 축열탱크(210)의 축열이 설정온도에 도달되지 못하면 3방향 밸브(286)가 동작되어 축열탱크(210)와 보조열원 열교환기(274) 사이를 연통시켜 축열탱크(210)의 열수가 보조열원 열교환기(274)를 통과하도록 한다. 그리고, 보조열원 발생부(272)가 작동되어 보조열원을 발생시키고, 이 보조열원이 축열탱크(210)의 열수와 열교환되어 열수를 가열한다. 이와 같이, 보조열원에 의해 축열탱크(210)가 추가적으로 축열되어 부족한 태양열 에너지를 보완하게 된다.When the heat storage of the thermal storage tank 210 does not reach the set temperature due to insufficient solar thermal energy due to cloudy or rainy weather, an insufficient heat source is supplied to the thermal storage tank 210 using an auxiliary heat source. That is, if the heat storage of the heat storage tank 210 does not reach the set temperature, the three-way valve 286 is operated to communicate between the heat storage tank 210 and the auxiliary heat source heat exchanger 274 so that the heat of the heat storage tank 210 is It passes through the auxiliary heat source heat exchanger (274). Then, the auxiliary heat source generating unit 272 is operated to generate an auxiliary heat source, and the auxiliary heat source heats the hot water by exchanging heat with the hot water in the heat storage tank 210 . In this way, the thermal storage tank 210 is additionally stored by the auxiliary heat source to compensate for insufficient solar thermal energy.

그리고, 태양열 에너지가 충분할 경우 보조열원 발생부(272)의 작동은 정지된다.And, when the solar heat energy is sufficient, the operation of the auxiliary heat source generating unit 272 is stopped.

이와 같은 본 발명의 일 실시예에 따른 태양열 급탕 및 냉난방 시스템은 태양열이 부족하여 축열탱크의 온도가 설정온도(약 90℃)에 도달되지 못할 경우 보조열원 공급부가 작동되어 축열탱크에 부족한 만큼의 열원을 제공하여 축열탱크의 온도가 설정온도 이상을 유지할 수 있도록 함으로써, 에너지 이용효율을 극대화 할 수 있게 된다.In the solar hot water supply and heating/cooling system according to an embodiment of the present invention, when the temperature of the thermal storage tank does not reach the set temperature (about 90° C.) due to insufficient solar heat, the auxiliary heat source supply unit is operated to supply enough heat to the thermal storage tank. By providing this, the temperature of the thermal storage tank can be maintained above the set temperature, thereby maximizing the energy use efficiency.
