The refrigerant gas evaporated from the evaporator 130 is exchanged with the rare absorbent liquid supplied to the high temperature heat exchanger 160 through the low temperature heat exchanger 150 from the low temperature regenerator 110 and supplied to the absorber 140. The absorbed liquid is absorbed into the concentrated absorbent liquid and converted into the diluted absorbent liquid, and the rare absorbent liquid is collected in the rare absorbent liquid receiver 141 under the absorber 140. The rare absorbent liquid collected in the rare absorbent liquid receiving unit 141 is supplied to the low temperature heat exchanger 150, thereby exchanging heat with the concentrated absorbent liquid supplied from the low temperature regenerator 110 to the low temperature heat exchanger 150 as described above. The high temperature regenerator 100 is supplied to the high temperature regenerator 100.

According to the operation mode of cooling or heating, when the heating valve 170 is opened, the condensation refrigerant is supplied from the condenser 120 to the upper part of the evaporator 130. When the heating valve 172 is opened, the refrigerant gas discharged from the high temperature regenerator 100 is supplied to the absorber 140. In addition, when the concentrated absorbent liquid pump 182 is driven, the hot concentrated absorbent liquid generated after the heat exchange with the high temperature refrigerant gas in the low temperature regenerator 110 is supplied to the low temperature heat exchanger 150 through the concentrated absorbent liquid supply pipe 183. Then, the rare absorbent liquid supplied from the low temperature heat exchanger 150 toward the high temperature heat exchanger 160 and the concentrated absorbent liquid are heat-exchanged, and then the concentrated absorbent liquid is sprayed upwardly to the absorber 140. In addition, when the heating valve 173 is opened, the intermediate absorbent liquid is supplied to the rare absorbent receiver 141 from the high temperature regenerator 100 side, and thus absorbed to the absorbent liquid supplied to the absorber 140 or the rare absorbent receiver 141. The evaporated refrigerant gas is absorbed into the rare absorbent liquid.

한편, 상기 냉매가스에 포집된 액상의 냉매는 증발기(130) 하부의 냉매액받이(131)에 포집되는데, 상기 냉매액받이(131)에 포집된 냉매는 난방밸브(171)의 개방시에는 희흡수액받이(141)로 공급되고, 또한 냉매펌프(180)의 구동에 따라 냉매액받이(131)로부터 바이패스배관(186)을 통해 다시 흡수기(140)의 상부로 바이패스 공급된다. Meanwhile, the liquid refrigerant collected in the refrigerant gas is collected in the refrigerant liquid receiver 131 under the evaporator 130. The refrigerant collected in the refrigerant liquid receiver 131 is rare when the heating valve 171 is opened. It is supplied to the absorption liquid receiver 141, and is also bypassed from the refrigerant liquid receiver 131 to the upper portion of the absorber 140 through the bypass pipe 186 according to the driving of the refrigerant pump 180.

상기 희흡수액받이(141)에 포집된 희흡수액은, 저온열교환기(150) 및 고온열교환기(160)를 차례로 거치게 된다. 즉, 상기 희흡수액은, 농흡수액펌프(182)의 구동시 저온재생기(110)측으로부터 흡수기(140)로 공급되는 농흡수액과 상기 저온열교환기(150)에서 열교환되고, 상기 저온열교환기(150)로부터 배출되는 희흡수액은, 고온재생기(100)측으로부터 저온재생기(110)측으로 공급되는 중간흡수액과 상기 고온열교환기(160)에서 열교환된 다음, 고온재생기(100)로 공급된다. The rare water absorbed by the rare water absorbing receiver 141 is sequentially passed through the low temperature heat exchanger 150 and the high temperature heat exchanger 160. That is, the rare absorbent liquid is heat-exchanged in the low temperature heat exchanger 150 and the concentrated absorbent liquid supplied from the low temperature regenerator 110 to the absorber 140 when the concentrated absorbent liquid pump 182 is driven. The rare absorbent liquid discharged from the heat exchanger is heat-exchanged with the intermediate absorbent liquid supplied from the high temperature regenerator 100 side to the low temperature regenerator 110 side, and then supplied to the high temperature regenerator 100.

한편, 증발기(130)로 냉수를 공급하여 열교환에 의해 냉각하여 배출함으로써, 냉각된 냉수를 냉방에 활용하는 냉방모드를 가동할 경우에, 본 발명에서는 급탕 온수도 동시에 공급할 수 있다. On the other hand, by supplying cold water to the evaporator 130, and cooled by heat exchange to discharge, when operating the cooling mode to utilize the cooled cold water for cooling, in the present invention, hot water supply hot water can be supplied at the same time.

즉, 농흡수액펌프(182)를 가동하면, 저온재생기(110)에서 고온의 냉매가스와 열교환된 이후 발생된 고온의 농흡수액이 농흡수액 공급배관(183)을 통하여 저온열교환기(150)로 공급되는데, 이 과정에서 상기 고온의 농흡수액이 급탕열교환기(220)를 거치게 된다. That is, when the concentrated absorbent liquid pump 182 is operated, the high temperature concentrated absorbent liquid generated after the heat exchange with the high temperature refrigerant gas in the low temperature regenerator 110 is supplied to the low temperature heat exchanger 150 through the concentrated absorbent liquid supply pipe 183. In this process, the hot concentrated absorbent liquid is subjected to the hot water supply heat exchanger (220).

따라서, 급탕열교환기(220)를 거치는 고온의 농흡수액과, 급탕수 입구관(221)을 통해 급탕열교환기(220) 내부 및 팽창탱크(230)의 내부로 공급되는 저온의 급탕수가 서로 열교환되므로, 저온의 급탕수가 고온의 농흡수액에 의하여 가열되어 고온의 급탕 온수로 바뀌어 급탕수 출구관(222)을 통해 배출되므로, 상기 고온의 급탕 온수를 원하는 장소로 공급하여 활용할 수 있게 된다. Therefore, since the hot absorbent liquid passing through the hot water supply heat exchanger 220 and the low temperature hot water supplied to the inside of the hot water heat exchanger 220 and the expansion tank 230 through the hot water inlet pipe 221 are exchanged with each other. The low-temperature hot water supply is heated by the hot concentrated absorbent liquid and is converted into high-temperature hot water supply hot water and discharged through the hot water supply outlet pipe 222, so that the hot water hot water supply can be supplied to a desired place.

그리고, 원하는 고온의 급탕 온수를 공급할 수 없을 경우나, 흡수식 냉온수기의 가동을 중단한 휴지기간 중에 고온의 급탕 온수를 공급하고자 할 경우에, 급탕수 입구관(221)을 통해 급탕열교환기(220)의 내부로 저온의 급탕수를 공급하고, 소형버너(240)를 가동하여 급탕열교환기(220)의 내부를 가열하면, 저온의 급탕수가 고온의 급탕수의 바뀌어 급탕수 출구관(222)을 통해 배출될 수 있으므로, 냉방시나 휴지시에도 고온의 급탕 온수를 공급할 수 있게 된다. And, if it is not possible to supply the hot water of the hot water supply desired, or if you want to supply hot water of hot water during the rest period when the operation of the absorption type cold water heater, the hot water supply heat exchanger 220 through the hot water supply inlet pipe 221 When the low-temperature hot water is supplied to the inside of the hot water supply and the small burner 240 is operated to heat the inside of the hot water heat exchanger 220, the low-temperature hot water is changed into the hot water and the hot water is supplied through the hot water supply outlet pipe 222. Since it can be discharged, it is possible to supply hot water of hot water at the time of cooling or rest.

상기한 바와 같이 구성된 본 발명에 따른 흡수식 냉온수기의 냉방 또는 휴지시 급탕장치에 의하면, 냉방모드의 가동시에 저온재생기(110)에서 고온의 냉매가스와 열교환된 이후 발생된 고온의 농흡수액과 저온의 급탕수를 급탕열교환기(220)에서 서로 열교환시켜, 상기 저온의 급탕수를 가열하여 고온의 급탕 온수로 만들어 배출할 수 있으므로, 냉방과 급탕을 동시에 사용할 수 있다. According to the hot water supply device during cooling or resting of the absorption type cold and hot water heater according to the present invention configured as described above, the high temperature concentrated absorbent liquid and the low temperature generated after heat exchange with the high temperature refrigerant gas in the low temperature regenerator 110 during the operation of the cooling mode The hot water is exchanged with each other in the hot water heat exchanger 220 to heat the low temperature hot water to make hot water hot water and discharge the hot water, so that cooling and hot water can be used simultaneously.

또한, 고온의 농흡수액을 활용하여 급탕 온수를 생성함으로써, 열효율을 높일 수 있고, 냉방부하에 지장을 초래하지 않으며, 급탕 부하가 큰 경우에도 소망하는 온도의 급탕 온수를 얻을 수 있다. In addition, by producing hot water supply hot water by utilizing the hot concentrated absorbent liquid, it is possible to increase the thermal efficiency, do not interfere with the cooling load, it is possible to obtain the hot water supply hot water of the desired temperature even when the hot water load is large.

또한, 원하는 고온의 급탕 온수를 공급할 수 없을 경우나, 흡수식 냉온수기의 가동을 중단한 휴지기간 중에도, 소형버너(240)를 가동하여 급탕열교환기(220)의 내부를 가열함으로써, 고온의 급탕 온수를 공급할 수 있으므로, 사용상 편리하다. In addition, when the hot water supply of the desired hot water cannot be supplied or during the rest period during which the absorption cold / hot water heater is stopped, the small burner 240 is operated to heat the inside of the hot water supply heat exchanger 220, thereby producing hot hot water supply. As it can supply, it is convenient for use.

또한, 냉방모드를 가동할 필요가 없어 흡수식 냉온수기의 가동을 중지시킨 휴지기간 중에, 소형버너(240)만을 가동하여 고온의 급탕 온수를 공급할 수 있어, 흡수식 냉온수기를 가동할 필요가 없으므로, 경제적인 효과를 얻을 수 있으며, 흡수식 냉온수기의 기능도 확대시킬 수 있다.In addition, since the cooling mode does not need to be operated, only the small burner 240 can be operated to supply hot water and hot water supply during the rest period when the absorption chiller is stopped. Therefore, it is not necessary to operate the absorption chiller. It can be obtained, and the function of the absorption chiller can be expanded.
