본 고안은 흡수식 냉동기에서 나오는 냉각수를 직수와 열교환시키고 이 열교환기를 통해서 나오는 냉각수를 냉각탑으로 유입시켜 냉각한 후 다시 흡수식 냉동기로 보내고 열교환기를 거친 직수는 히터로 유입시켜 에너지를 절약하고 환경에 기여할 수 있는 축열작용을 가진 흡수식 냉동기에 관한 것이다.The present invention heats the coolant from the absorption chiller with direct water, cools the cooling water from the heat exchanger to the cooling tower, cools it, and sends it to the absorption chiller again. The direct water passed through the heat exchanger enters the heater to save energy and contribute to the environment. It relates to an absorption chiller having a heat storage action.

종래의 흡수식 냉동기의 경우, 제1도에 도시한 바와 같이, 흡수식 냉동기(1)에서 유출되는 유출수는 38℃이고 이를 냉각탑(2)에서 32℃로 냉각시켜 흡수식 냉동기(1)로 다시 유입시키는 냉각수 유통경로를 가지므로, 종래의 흡수식 냉동기는 온수를 공급하기 위해서는 별도로 급탕보일러(3)를 설치하여 온수를 공급하였으나 이는 에너지의 이용효율이 저하되고 에너지를 과잉소비한다는 문제점이 있다.In the case of the conventional absorption chiller, as shown in FIG. 1, the effluent flowing out of the absorption chiller 1 is 38 ° C, and the cooling water is cooled to 32 ° C in the cooling tower 2 and flows back into the absorption chiller 1 again. In order to supply hot water, the conventional absorption type refrigerator has a separate hot water supply boiler 3 to supply hot water, but this has a problem in that energy use efficiency is lowered and energy is excessively consumed.

본 고안의 목적은, 이러한 문제점을 해결하기 위한 것으로, 흡수식 냉동기에서 유출되는 냉각수의 폐열을 활용하므로서 냉각탑의 부하를 감소시키고 온수가열용 히터의 부하를 감소시켜 에너지의 이용효율을 높이도록 한 축열작용을 가진 흡수식 냉동기를 제공하는 것이다.An object of the present invention is to solve this problem, by utilizing the waste heat of the cooling water flowing out of the absorption chiller to reduce the load of the cooling tower and to reduce the load of the heater for hot water heating to increase the energy utilization efficiency It is to provide an absorption chiller having a.

본 고안의 이러한 목적은 흡수식 냉동기에서 나오는 냉각수가 축열식 열교환기에서 직수와 열교환된 후 냉각탑에 보내져 냉각된 후 다시 흡수식 냉동기로 유입되도록 축열식 열교환기를 설치한 본 고안의 흡수식 냉동기에 의해 달성된다.This object of the present invention is achieved by the absorption chiller of the present invention in which the cooling water from the absorption chiller is heat-exchanged with the direct water in the heat storage heat exchanger, is then sent to the cooling tower, cooled, and then flows back into the absorption chiller.

본 고안에 따른 축열작용을 가진 흡수식 냉동기를 첨부된 도면을 참고로하여 이하의 상세한 설명에 의하여 명백하게 이해할 수 있을 것이다.With reference to the accompanying drawings, the absorption chiller having a heat storage action according to the present invention will be clearly understood by the following detailed description.

제2도는 본 고안에 따른 축열작용을 가진 흡수식 냉동기로서, 흡수식 냉동기(1)의 냉각수 유출관(4)이 연결되고 직수유입관(5)이 연결되며 냉각수 배출관(6)이 냉각탑(2)에 연결되는 축열식 열교환기(7)와, 축열식 열교환기(7)에서 배출되는 직수를 가열하는 히터(8)가 설치된 구조이다.2 is an absorption chiller having a heat storage action according to the present invention, a cooling water outlet pipe 4 of the absorption chiller 1 is connected, a direct inlet pipe 5 is connected, and a cooling water discharge pipe 6 is connected to the cooling tower 2. The heat storage heat exchanger 7 to be connected and the heater 8 for heating the water discharged from the heat storage heat exchanger 7 are provided.

이와 같은 구조의 본 고안에 따른 흡수식 냉동기의 작동을 설명하면, 흡수기 냉동기(1)에서 38℃온도로 냉각수 유출관(4)을 통해 배출되는 냉각수를 온도가 T1(25℃이하)인 직수와 축열식 열교환기(7)에서 열교환한 후 온도가 T4(38℃)가 되어서 냉각탑(2)으로 유입되고, 또 축열식 열교환기(7)를 통과한 직수는 T2(T1)가 되어서 히터(8)로 유입된다.Referring to the operation of the absorption type refrigerator according to the present invention of such a structure, the coolant discharged through the coolant outlet pipe 4 at 38 ° C. in the absorber freezer 1 and the direct water having a temperature of T 1 (25 ° C. or less). After the heat exchange in the heat storage heat exchanger (7), the temperature is T 4 (38 ℃) flows into the cooling tower (2), and the direct water passing through the heat storage heat exchanger (7) is T 2 (T 1 ) is a heater ( 8) flows into.

여기서 냉각탑(2)을 보면 냉각탑(2)으로 유입되는 냉각수의 온도가 열용량이 큰 축열재를 설치한 축열식 열교환기(7)를 통과하기 때문에 냉각탑(2)에서 냉각수의 열량을 많이 탈취하지 않아도 기존 방식에 의해서 냉각탑에서 나가는 냉각수 온도와 같게 유지할 수 있기 때문에 냉각탑에 걸리는 부하도 적게되고 냉각탑에서 소모되는 전력도 절약된다.In the cooling tower 2, the temperature of the cooling water flowing into the cooling tower 2 passes through a heat storage heat exchanger 7 provided with a heat storage material having a large heat capacity. Therefore, the cooling tower 2 does not need to deodorize much heat of the cooling water. By maintaining the same temperature as the cooling water exiting the cooling tower, the load on the cooling tower is reduced and the power consumed by the cooling tower is saved.

또한 히터(8)로 유입되는 직수의 경우도 기존방식에 의한 직수입구 온도T1보다 높게 되므로 즉 T2T1이므로 히터에 가하는 열량도 적게되어 Q1' Q1이므로 소비되는 에너지를 줄일 수 있다.In addition, the direct water flowing into the heater 8 is also higher than the direct inlet temperature T 1 according to the conventional method, that is, since it is T 2 T 1 , the amount of heat applied to the heater is also reduced and Q 1 'Q 1, so energy consumption can be reduced. .

본 고안의 히터는 종래의 급탕보일러와 달리 표현되고 있지만 온수공급수단으로의 작용은 동일하며, 종래의 급탕보일러와의 다른 점은 상기 직수 유입관(5)이 연결됨으로해서 직수가 예열된 상태에서 공급되어 온수로 될 때까지 히터 또는 급탕보일러에 걸리는 부하가 현저히 줄어드는 데에 있다.The heater of the present invention is expressed differently from the conventional hot water boiler, but the function of the hot water supply means is the same, and the difference from the conventional hot water boiler is that the direct water inlet pipe 5 is connected, so that the direct water is preheated. The load on the heater or the hot water boiler until it is supplied to the hot water is significantly reduced.

이상과 같이 본 고안에 따른 축열작용을 가진 흡수식 냉동기는 흡수식냉동기에서 유출되는 유출수의 폐열을 활용하므로서 냉각탑의 부하를 감소시키고 온수가열용 히터의 부하를 감소시켜 에너지의 이용효율을 높히고 유지비 및 설치비가 저렴하게되는 우수한 효과가 있다.As described above, the absorption chiller having the heat storage action according to the present invention utilizes the waste heat of the effluent flowing out of the absorption chiller, thereby reducing the load of the cooling tower and reducing the load of the heater for hot water heating, thereby increasing energy utilization efficiency and maintaining and installing costs. There is an excellent effect of being cheaper.
