본 발명은 흡착식 냉동기에 관한 것으로, 특히 흡착식 냉동기의 폐열 재활용을 위한 히트펌프 장치에 관한 것이다.The present invention relates to an adsorption freezer, and more particularly to a heat pump apparatus for waste heat recycling of the adsorption freezer.

흡착식 냉동기는 흡착제와 냉매(물)의 가열반응에 따르는 발열, 흡열현상을 이용하고 배열을 열원으로하여 냉열을 발생시키는 냉동열기관이다. 이 시스템은 흡착제 열교환기(재생·흡착공정), 응축기, 증발기로 구성되는 밀폐계의 고진공으로 되어 있고, 흡착제로는 실리카(Silic)계 또는 제올라이트(Zeolite)계의 고체흡착제가 주로 사용되고 있다.Adsorption-type freezer is a refrigerating heat engine that uses the heat generated by the heating reaction of the adsorbent and the refrigerant (water) and the endothermic phenomenon, and generates heat by using the heat source as the heat source. This system is a closed system high vacuum composed of an adsorbent heat exchanger (regeneration / adsorption process), a condenser, and an evaporator. As the adsorbent, a solid adsorbent of silica or zeolite is mainly used.

상기 흡착식 냉동기는 한 쪽의 흡수재생기가 냉매를 흡수할 때에 다른 쪽의 흡수재생기는 보일러에서 보내져 오는 수증기를 이용해서 흡착제를 재생하게 된다. 재생이 완료되면, 증기와 냉매가 재생이 완료된 흡착제를 흡착에 사용하고, 흡착에 사용하지 않은 쪽에서 냉매를 흡착한 흡착제의 재생을 실행하는 일련의 과정을 반복하면서 연속적으로 냉동출력을 얻게 된다.The adsorption-type refrigerator regenerates the adsorbent using the water vapor sent from the boiler when one absorption regenerator absorbs the refrigerant. When the regeneration is completed, the freezing output is continuously obtained while repeating a series of processes in which steam and refrigerant use the regenerated adsorbent for adsorption, and regenerate the adsorbent in which the refrigerant is adsorbed on the side not used for adsorption.

여기서, 상기 흡착제가 냉매를 원활하게 흡착하기 위해서나 또는 상기 응축 기에서 냉매를 원활하게 응축하기 위해서는 상기 흡수재생기와 응축기가 냉각수나 공기에 의해 지속적으로 냉각되도록 하여야 한다. 이를 위해, 통상 냉각탑(Cooling Tower)을 설치하여 그 냉각탑에서 공급되는 냉각수를 이용하여 상기 흡수재생기와 응축기를 냉각하고 있다.Here, in order to adsorb the refrigerant smoothly or to condense the refrigerant in the condenser smoothly, the absorption regenerator and the condenser must be continuously cooled by cooling water or air. To this end, a cooling tower is usually installed to cool the absorption regenerator and the condenser using the cooling water supplied from the cooling tower.

그러나, 상기와 같은 종래 흡착식 냉동기에 있어서는, 상기 냉각탑을 통해 흡수재생기와 응축기와 열교환되어 가열된 냉각수가 그 냉각열을 공기중에 방출함에 따라 에너지 손실과 온실효과를 가중시키는 문제점이 있었다.However, in the conventional adsorption-type freezer as described above, there is a problem in that the cooling water heated by heat exchange with the absorption regenerator and the condenser through the cooling tower increases the energy loss and the greenhouse effect as the cooling heat is released into the air.

본 발명은 상기와 같은 종래 흡착식 냉동기가 가지는 문제점을 해결한 것으로, 상기 냉각탑에서 방열되는 열을 냉동기의 열원으로 재활용하여 에너지 손실과 온실효과를 낮추는 흡착식 냉동기의 폐열 재활용을 위한 히트펌프 장치를 제공하려는데 본 발명의 목적이 있다.The present invention solves the problems of the conventional adsorption-type freezer as described above, to provide a heat pump device for recycling the waste heat of the adsorption-type freezer to reduce energy loss and greenhouse effect by recycling the heat radiated from the cooling tower to the heat source of the freezer. There is an object of the present invention.

본 발명의 목적을 달성하기 위하여, 흡착제와 냉매의 가열반응에 따른 발열현상과 흡열현상을 이용하여 냉력을 발생하는 흡착식 냉동기와, 상기 흡착식 냉동기의 흡열측에 온수를 공급하는 온수 순환계통과, 상기 흡착식 냉동기의 발열측에 냉각수를 공급하는 냉각수 순환계통과, 상기 냉각수 순환계통의 중간에서 열에너지를 흡수하여 상기 온수 순환계통에 전달하는 히트펌프로 이루어진 것을 특징으로 하는 흡착식 냉동기의 폐열 재활용을 위한 히트펌프 장치가 제공된다.In order to achieve the object of the present invention, the adsorption-type freezer using the exothermic phenomenon and the endothermic phenomenon caused by the heating reaction of the adsorbent and the refrigerant, and the hot water circulation system for supplying hot water to the endothermic side of the adsorption-type freezer, The heat pump device for recycling the waste heat of the adsorption-type refrigerator comprising a cooling water circulation system for supplying cooling water to the heat generating side of the refrigerator, and a heat pump that absorbs heat energy in the middle of the cooling water circulation system and transfers it to the hot water circulation system.

상기와 같은 본 발명에 의한 흡착식 냉동기의 폐열 재활용을 위한 히트펌프 장치는 다음과 같은 작용 효과가 있다.Heat pump device for waste heat recycling of the adsorption-type refrigerator according to the present invention as described above has the following effects.

즉, 상기 온수 순환계통(70)의 제2 전열관(61)을 통해 고온수가 상기 제1 흡수재생기(11)로 공급되면, 그 제1 흡수재생기(11)의 흡착제는 고온의 열원에 의하여 열을 받아 가열되면서 상기 흡착제에서 냉매(물)가 탈착되고, 이 흡착제에서 탈착된 증기는 상기 제1 흡수재생기(11)의 내부 증기압이 응축기(13)의 압력보다 높으므로 상기 응축기(13)로 이동을 하게 된다. That is, when the hot water is supplied to the first absorption regenerator 11 through the second heat transfer pipe 61 of the hot water circulation system 70, the adsorbent of the first absorption regenerator 11 receives heat by a high temperature heat source. The refrigerant (water) is desorbed from the adsorbent while being heated, and the vapor desorbed from the adsorbent is moved to the condenser 13 because the internal vapor pressure of the first absorption regenerator 11 is higher than the pressure of the condenser 13. Done.

이와 동시에, 상기 증발기(14)와 연결되는 상기 제2 흡수재생기(12)는 상기 냉각수 순환계통(50)의 제1 전열관(51)에 의해 중간온도에서 외부로 열을 방출하면서 일정온도로 유지되어 상기 제2 흡수재생기(12)의 내부 증기압이 증발기(14)의 압력보다 낮아지게 되고, 이에 따라 상기 증발기(14)에서 증발되어 발생되는 증기가 상기 제2 흡수재생기(12)로 이동하여 그 제2 흡수재생기(12)의 흡착제에 흡착되는 일련의 과정을 상기 제1 흡수재생기(11)와 제2 흡수재생기(12)에서 번갈아 진행 하게 된다. At the same time, the second absorption regenerator 12 connected to the evaporator 14 is maintained at a constant temperature while dissipating heat from the intermediate temperature to the outside by the first heat transfer pipe 51 of the cooling water circulation system 50. The internal vapor pressure of the second absorption regenerator 12 is lower than the pressure of the evaporator 14, so that the vapor generated by evaporation in the evaporator 14 moves to the second absorption regenerator 12 and is formed. A series of processes of adsorbing the adsorbent of the second absorption regenerator 12 are alternately performed in the first absorption regenerator 11 and the second absorption regenerator 12.

이 과정에서, 상기 증발기(14)는 상기 응축기(12)에서 응축된 응축수가 지속적으로 회수되면서 그 응축수가 상기 냉수 순환계통의 제3 전열관(17)을 흐르는 냉매가 증발되어 냉동효과를 얻게 되는 것이다.In this process, the evaporator 14 is to recover the condensate condensed in the condenser 12 continuously while the refrigerant flowing through the third heat pipe 17 of the cold water circulation system is evaporated to obtain a freezing effect. .

한편, 상기 흡착식 냉동기(10)의 흡수재생기(11)(12)와 응축기(13)에서 발생되는 흡착열과 응축열은 상기 냉각수 순환계통(50)의 제1 전열관(51)을 통해 상기 냉각탑(30)으로 전달하여 외부로 방출하게 되나, 이 흡착열과 응축열은 상기 냉각수 순환계통(50)의 중간에 연결되는 상기 냉각수 우회계통(70)을 통해 회수되어 상기 히트펌프(40)의 증발기(44)를 증발시키게 된다. 상기 히트펌프(40)의 증발기(44)에서 증발된 냉매(프레온 등)는 그 히트펌프(40)의 압축기(41)에서 압축된 후 히트펌프(40)의 응축기(42)로 이동하여 응축된다. 이 히트펌프(40)의 응축기(42)에서 응축된 냉매는 다시 히트펌프(40)의 팽창변(43)을 거쳐 히트펌프(40)의 증발기(44)와 압축기(41)를 순환하는 과정을 반복하게 된다.Meanwhile, the heat of adsorption and the heat of condensation generated by the absorption regenerators 11 and 12 and the condenser 13 of the adsorption-type refrigerator 10 are transferred to the cooling tower 30 through the first heat pipe 51 of the cooling water circulation system 50. The heat of adsorption and the heat of condensation are recovered through the cooling water bypass system 70 connected to the middle of the cooling water circulation system 50 to evaporate the evaporator 44 of the heat pump 40. Let's go. The refrigerant evaporated in the evaporator 44 of the heat pump 40 is compressed by the compressor 41 of the heat pump 40 and then moved to the condenser 42 of the heat pump 40 to condense. . The refrigerant condensed in the condenser 42 of the heat pump 40 passes through the expansion valve 43 of the heat pump 40 and circulates the evaporator 44 and the compressor 41 of the heat pump 40 again. Done.

이때, 상기 온수 순환계통(60)의 중간에 온수 가열계통(80)이 연결되고, 그 온수 가열계통(80)이 상기 히트펌프(40)의 응축기(42)에 연결됨에 따라 상기 히트펌프(40)의 응축기(42)에서 냉매가 응축되는 과정중에 발생하는 응축열이 상기 온수 가열계통(80)으로 흐르는 저온수를 고온수로 가열하여 상기 흡착식 냉동기(10)의 흡수재생기(11)(12)에 공급하게 된다.In this case, the hot water heating system 80 is connected to the middle of the hot water circulation system 60, and the hot water heating system 80 is connected to the condenser 42 of the heat pump 40. Heat of condensation generated during the condensation of the refrigerant in the condenser 42 of the heating unit is heated to the hot water heating system 80 with high temperature water to the absorption regenerators 11 and 12 of the adsorption-type refrigerator 10. Will be supplied.
