그러나 사무실 등의 집단 건물 등은 냉·난방과 동시에 목욕용 또는 급탕용 온수(이하“급탕용 온수”라함)를 필요로 하는 바, 상기 흡수식 냉동기는 증발기(5) 내에 설치한 냉·온수겸용 열교환관(5')에서 냉·난방용 냉수 또는 온수만을 생성할 수 있음으로 흡수식 냉동기를 냉·난방용으로 설치한 경우에는 급탕용 온수를 생성하기 위한 온수 보일러를 각각 별도로 설치하고 있는 실정임으로 불편하고, 비용이 많이 소요되고 있다.However, in a group building such as an office, the hot water for bathing or hot water (hereinafter referred to as "hot water for hot water") is required at the same time as cooling and heating, and the absorption chiller is a cold / hot water heat exchanger tube installed in the evaporator 5. (5 ') can generate only cold water or hot water for cooling and heating, so when the absorption chiller is installed for cooling and heating, it is inconvenient and expensive to install separate hot water boilers to generate hot water for hot water supply. It takes a lot.
상기한 흡수식 냉동기와 급탕용 온수 보일러를 각각 별도로 설치하는 문제점을 해결하기 위하여, 흡수식 냉동기의 고온 재생기에 급탕용 온수 가열기를 연결하고, 상기 급탕용 온수 가열기에 고온 재생기에서 발생한 냉매증기의 일부를 공급하여서 냉·난방용 냉수 또는 온수와 함께 급탕용 온수를 생성하는 것이 알려졌다.In order to solve the problem of separately installing the absorption chiller and the hot water boiler for the hot water supply, the hot water heater for the hot water heater is connected to the high temperature regenerator of the absorption chiller, and a portion of the refrigerant steam generated in the hot water regenerator is supplied to the hot water heater for the hot water heater. Therefore, it is known to generate hot water for hot water together with cold water for heating and cooling.
그러나 상기와 같이 고온 재생기에서 발생한 냉매증기에 의하여 냉·난방용 냉수 또는 온수와 급탕용 온수를 함께 생성할 경우, 난방용 온수와 급탕용 온수를 함께 생성할 경우에는 고온 재생기의 용량을 급탕용 온수의 가열에 필요한 만큼 확대하면 별문제점은 없게 된다. 그렇지만 냉방용 냉수와 급탕용 온수를 함께 생성할 경우에는 급탕용 온수의 생성온도를 일정온도가 유지되도록 운전할 때 냉방부하가 감소되면 급탕용 온수 발생량이 감소하고, 또한 냉방부하의 감소에 의하여 냉방용 냉수 발생량이 저하되면 고온 재생기의 압력 및 온도가 저하되고 급탕용 온수의 온도가 저하되는 현상이 발생함으로써 급탕용 온수의 생성량 및 온도가 불균일하고, 냉매 싸이클 및 흡수액 싸이클의 불평형에 의하여 흡수식 냉동기의 능력이 감소함과 동시에 효율이 저하되는 문제점이 발생하는 것이다.However, when the cooling and heating cold water or the hot water and the hot water for hot water are generated together by the refrigerant steam generated in the high temperature regenerator as described above, when the heating hot water and the hot water for hot water are generated together, the capacity of the hot water regenerator is heated. If you zoom in as much as you need, there is no problem. However, when cooling cold water and hot water for hot water are generated together, the amount of hot water for hot water is reduced when the cooling load is reduced while operating the generated temperature of the hot water for hot water to maintain a constant temperature. When the amount of cold water is lowered, the pressure and temperature of the high temperature regenerator are lowered and the temperature of the hot water for hot water is lowered. Thus, the amount and temperature of the hot water for hot water are uneven, and the capacity of the absorption chiller is unbalanced by the refrigerant cycle and the absorbent cycle. This decrease and at the same time the problem that the efficiency is lowered.
본 발명은 상기한 실정을 감안하여, 고온 재생기에서 배출되는 폐열에 의하여 냉·난방용 냉수 또는 온수와 함께 급탕용 온수를 냉동기의 능력감소 및 효율저하 없이 양호하게 생성할 수 있는 흡수식 냉동기의 급탕용 온수 가열장치를 제공하는 것을 목적으로 한다. In view of the above-described circumstances, the hot water for hot water supply of the absorption type refrigerator which can generate hot water for hot water supply together with the cold / hot water for cooling / heating or the hot water by the waste heat discharged from the high temperature regenerator without sacrificing the efficiency and the efficiency of the freezer.

After heating and evaporating the heat medium in the heated water pipe 31 by the waste heat discharged to the flue 30, the heat medium liquid rises to the radix header 32, and then the heat medium liquid passes through the precipitation pipe 34 to the water header 33. By natural circulation, the heat medium vapor is circulated by the density difference through the supply pipe 40 to the shell 36 of the shell tube heat exchanger 35 in the first embodiment, the hot water to be stored in the storage tank 43 While circulating the tube 37 of the shell tube heat exchanger (35) forms a heating path that is heated by heat exchange with heat transfer and then returned to the water storage tank (43), and the hot water heated in the shell tube heat exchanger (35) and Cooled by heat exchange Liquid medium is re-heated and then moved back to the number of header 33 by way of the water exchange tube (41) to repeat the above cycle.
한편 제 2 실시예에서는 기수헤더(32)에서 열매체액과 열매체증기가 분리된 후 열매체증기는 공급관(40)을 통하여 저탕조(43)에 내장된 열교환기(47)를 순환하면서 저탕조(43)내의 가열될 온수와 열교환하여 급탕용 온수를 직접 생성하고 환수관(41)을 경유하여 수헤더(33)에 되돌아 가서 재가열되어 상기한 사이클을 반복하는 것이다. Meanwhile, in the second embodiment, after the heat medium liquid and the heat medium vapor are separated from the radix header 32, the heat medium vapor is circulated through the heat exchanger 47 built in the low temperature tank 43 through the supply pipe 40, and then the low temperature water tank 43 Heat exchange with the hot water to be heated in) to directly generate hot water for hot water supply, and return to the water header 33 via the return pipe 41 and reheated to repeat the above cycle.
