It is possible to provide centralized management, and it is not necessary to install supplementary water pipes and drainage pipes separately, and to provide a separate cooling system for low temperature water absorption type cooling system for central supply of cooling water that can solve the problem of deterioration of efficiency.

따라서, 상기와 같은 구성에 의한 본 고안의 목적이 구체적으로 실현될수 있는 본 고안의 실시예가 첨부된 도면을 참조하여 구체적으로 설명된다.Accordingly, embodiments of the present invention in which the object of the present invention by the above configuration can be specifically realized will be described in detail with reference to the accompanying drawings.

먼저 도2 에서와 같이 저온수 흡수식 냉동기(1)의 상세한 구조와 냉방의 원리에 대한 설명을 한다. 흡수액의 흐름은, 흡수기(30)상부의 트레이로부터 흡수기(30)내의 냉각수 전열관위로 적하되며 엘리미네이터 사이로 넘어온 냉매를 흡수하여 흡수기(30)바닥에 모이게 된다. 이때 농도는 흡수액이 트레이로 흐르기 전보다 훨씬 묽은 상태가 된다.First, the detailed structure and cooling principle of the low temperature water absorption refrigerator 1 will be described as shown in FIG. 2. The flow of the absorbent liquid is dropped from the tray above the absorber 30 onto the coolant heat transfer tube in the absorber 30, and absorbs the refrigerant that has passed between the eliminators and collects at the bottom of the absorber 30. At this time, the concentration becomes much thinner than before the absorbent liquid flows to the tray.

이때 정상 운전시 농도는 58％가량된다. 이를 희액이라 부르는데 모여진 희액을 흡수기(30)에서 흡수액 펌프(40)에 의해 열교환기(50)를 거쳐 온도가 높은 상태로 열교환되어 재생기(60)로 올라가게 된다. 재생기(60)에서 저온수에 의해 가열되면 희액에서 냉매가 증발하며 농도가 더 짙은 흡수액으로 만든 뒤 다시 열교환기(50)를 거치면서 더 낮아진 상태로 다시 흡수기(30)로 되돌아간다. 이와 같은 순환과정을 거쳐 흡수액으로 다시 냉매를 흡수하여 같은 방식으로 계속 순환된다.At this time, the concentration in normal operation is about 58%. This is called a rare liquid, and the collected rare liquid is heat-exchanged by the absorbent liquid pump 40 in the absorber 30 through the heat exchanger 50 to a high temperature, thereby rising to the regenerator 60. When heated by the low temperature water in the regenerator 60, the refrigerant evaporates in the lean solution, and the concentration is made into a thicker absorbent liquid, and then goes back to the absorber 30 in a lower state while passing through the heat exchanger 50 again. Through this circulation process, the refrigerant is absorbed back into the absorbent liquid and circulated in the same manner.

한편 냉매(H2 O)의 순환은 증발기(20)에서 냉매가 가장 증발하기 쉬운 조건인 밀폐된 진공상태 즉 증발기 내부압력 약 6mmHg와 4℃냉매 온도를 유지 시키면 냉매가 증발하면서 증발잠열을 빼앗아감으로서 전열관내의 물이 냉방에 필요한 냉수가 만들어지게 된다.On the other hand, the circulation of the refrigerant (H 2 O) is maintained in the sealed vacuum state, which is a condition where the refrigerant is most likely to evaporate in the evaporator 20, that is, the internal pressure of about 6 mmHg and the refrigerant temperature of 4 ° C. maintains the refrigerant temperature and evaporates the latent heat of evaporation. As a result, the cold water required for cooling the water in the heat transfer tube is made.

이때 증기형태가 된 냉매는 흡수액에 의해 강력하게 흡수되어져 재생기(60)까지 흡수액과 함께 섞여 운반된다. 재생기(60)에서 저온수 가열원에 의해 가열되면 흡수액과 분리되고 증발된 냉매증기는 냉매인 물로 응축된다. 응축된 냉매는 응축기(70)로 이동하여 냉각탑(6)에서 냉각된 냉각수에 의해 재생기(60)에서 응축되지 못하고 남은 냉매증기는 응축기(70)의 냉각수에 의해 응축이 된다. 응축기(70)의 냉매는 증발기(20)로 회수되어 다시 상기과 같은 순서로 재순환 되는 냉매 싸이클을 형성하게 된다.At this time, the refrigerant in the form of vapor is strongly absorbed by the absorbent liquid and is mixed with the absorbent liquid to the regenerator 60 and transported. When heated by the low temperature water heating source in the regenerator 60 is separated from the absorbing liquid and the evaporated refrigerant vapor is condensed into water which is a refrigerant. The condensed refrigerant moves to the condenser 70 and is not condensed in the regenerator 60 by the cooling water cooled in the cooling tower 6, and the remaining refrigerant vapor is condensed by the cooling water of the condenser 70. The refrigerant of the condenser 70 is recovered to the evaporator 20 to form a refrigerant cycle that is recycled in the same order as described above.

상기 싸이클에서 응축기(70)에 필요한 냉각장치에 대해서 설명한다.The cooling device required for the condenser 70 in the cycle will be described.

도3 에서와 같이 각 저온수 흡수식 냉동기(1)를 가동하게 되면 냉각탑(6)이 가동되어 냉각된 냉각수가 냉각수 펌프(5)에 의해 각 저온수 흡수식 냉동에(1)의 응축기(70)에 필요한 야의 냉각수가 냉각수 공급관(3)을 통하여 냉각수 제어밸브(2)에 의해 공급되어지게 된다.As shown in FIG. 3, when each of the low temperature water absorption type refrigerators 1 is operated, the cooling tower 6 is operated to cool the cooled water to the condenser 70 of the low temperature water absorption type refrigerator 1 by the cooling water pump 5. Necessary coolant of the field is supplied by the coolant control valve 2 through the coolant supply pipe 3.

또한 이때 저온수 흡수식 냉동기(1)의 재생기(60)에 필요한 저온수 가열 열원(지역난방온수, 태양열, 연료전지폐열, 마이크로코젠폐열, 소각로폐열, 기타열원)도 열원수 제어밸브(7)과 열원수펌프(10)에 의해 필요한 양의 열원수를 열원수 공급관(9)를 통하여 열원수가 공급되어 진다.At this time, the low temperature water heating heat source (local heating hot water, solar heat, fuel cell waste heat, microgen waste heat, incinerator waste heat, and other heat sources) required for the regenerator 60 of the low temperature water absorption refrigerator 1 is also provided with a heat source control valve 7. The heat source water is supplied through the heat source water supply pipe 9 with the required amount of heat source water by the heat source water pump 10.

이상에서 본 고안의 장치구성 및 흡수액과 냉매와 냉각수의 흐름에 대하여 상기한 설명 및 도면에 따라 도시하였지만 이는 예를 들어 설명한 것에 불과하며 본 고안의 기술적 사상 및 범위를 벗어나지 않는 범위 내에서 다양한 변화 및 변경이 가능함은 물론이다.In the above configuration of the device of the present invention and the flow of the absorbent liquid and the coolant and the coolant are shown according to the above description and drawings, but this is just described, for example, and various changes and changes within the scope and spirit of the present invention. Of course, change is possible.

개별식 냉난방시스템으로 널리 사용되고 있는 전기열원 공냉식 또는 냉각탑 일체형 가스흡수식 냉난방기에 비해 설치비가 절감되고, 신재생 에너지인 태양열을 이용할 경우 정부 지원제도를 이용할수 있고, 또한 연료전지 발전시 발생되는 온수등 각종 폐열을 이용할 수 있고 누진제가 적용되는 주택용 전기 사용량을 절약함으로서 유지비를 대폭 절감할수 있기 때문에 고유가 시대에 본 고안에 의한 친환경 에너지 절약 시스템은 공동주택, 숙박시설, 오피스텔, 주상복합, 콘도미니엄등의 건물에 산업상 이용 가능성이 매우 높다고 할수 있다.The installation cost is reduced compared to the electric heat source air-cooled or integrated tower gas absorption air conditioner which is widely used as a separate air-conditioning system, and the government support system can be used when using renewable energy, solar, and hot water generated during the fuel cell power generation. In the era of high oil prices, the eco-friendly energy saving system of the present invention can be applied to buildings such as apartment houses, lodging facilities, officetels, residential complexes, and condominiums. Industrial availability is very high.
