그리고, 상기 물 사용공간(600)에는 저수조탱크(700)와 냉수공급라인(730)으로 연결되어 저수조탱크(700)의 냉수가 공급되고, 상기 냉수공급라인(730)의 일측에는 냉수공급라인(730)으로부터 분기되어 온수탱크(400)의 열방출라인(420)에 연결되어 온수순환라인(321)에 냉수를 공급하는 온수측 공급라인(732)이 설치된다.In addition, the water use space 600 is connected to the reservoir tank 700 and the cold water supply line 730 to supply cold water to the reservoir tank 700, and to one side of the cold water supply line 730, a cold water supply line ( The hot water supply line 732 is branched from 730 and connected to the heat discharge line 420 of the hot water tank 400 to supply cold water to the hot water circulation line 321.

상기 냉수공급라인(730)에는 저수조탱크(700)내의 냉수를 물 사용공간(600)과 열방출라인(420)으로 강제 공급하는 부스터펌프(731)가 설치된다.The cold water supply line 730 is provided with a booster pump 731 for forcibly supplying the cold water in the reservoir tank 700 to the water using space 600 and the heat discharge line 420.

또한, 상기 저수조탱크(700)는 폐회로의 냉각수라인(311)에 각각 공급라인(710)과 회수라인(720)으로 연결되고, 상기 공급라인(710)과 회수라인(720)에는 각각 냉방시 중지밸브(711)(721) 즉 냉방시 폐쇄되는 밸브가 설치된다.In addition, the reservoir tank 700 is connected to the cooling water line 311 of the closed circuit, respectively, by the supply line 710 and the recovery line 720, respectively, the cooling stop at the supply line 710 and the recovery line 720, respectively. Valves 711 and 721, that is, valves that are closed upon cooling, are installed.

이때, 상기 공급라인(710)은 냉각수가 공조기 및 팬코일(200)에서 증발부(310)측으로 회수되는 냉각수라인(311)에 연결되고, 상기 회수라인(720)은 냉각수가 증발부(310)에서 공조기 및 팬코일(200)측으로 공급되는 냉각수라인(311)에 연결됨이 바람직하다.At this time, the supply line 710 is connected to the cooling water line 311, the cooling water is recovered to the evaporator 310 side from the air conditioner and fan coil 200, the recovery line 720 is the cooling water evaporator 310 In the air conditioner and fan coil 200 is preferably connected to the cooling water line 311 is supplied.

이는, 상기 공급라인(710)에 의해 상기 공조기 및 팬코일(200)을 지나면서 고온화된 냉각수에 저수조탱크(700)의 냉수를 공급하여 냉각수의 저온화를 가속화시키고, 상기 회수라인(720)에 의해 냉동기(300)에서 열교환된 냉각수가 충분히 저온화되지 못한 경우 즉 저수조탱크(700)의 냉수보다 높은 온도일 경우 냉각수를 저수조탱크(700)로 바이패스시킴으로써 냉방시스템(100)의 냉방효율을 향상시키게 된다.This, by supplying the cold water of the reservoir tank 700 to the cooling water heated by passing through the air conditioner and the fan coil 200 by the supply line 710 to accelerate the lowering of the cooling water, to the recovery line 720 When the cooling water heat-exchanged in the refrigerator 300 is not low enough, that is, the temperature higher than the cold water of the reservoir tank 700 by bypassing the cooling water to the reservoir tank 700 to improve the cooling efficiency of the cooling system 100 Let's go.

여기서, 상기 냉방시스템(100)에는 냉각수나 온수 및 냉수의 온도를 감지하기 위한 온도감지센서 등이 각 라인상에 설치될 수 있다.Here, the cooling system 100 may be installed on each line a temperature sensor for sensing the temperature of the cooling water or hot water and cold water.

이와 같이 구성된 냉방시스템(100)은, 냉방시 공급라인(710)과 회수라인(720)상의 냉방시 중지밸브(711)(721)는 잠기고, 냉각수라인(311)상의 냉방시 사용밸브(312)(313)가 개방시킨 상태로서, 공조기 및 팬코일(200)에 냉각수라인(311)의 냉각수가 순환하여 냉방이 이루어진다. 그리고, 냉동기(300)에서 열교환된 열에너지는 온수순환라인(321)을 통해 응축부(320)를 지나는 온수로 전달되며, 또한 온수를 사용하지 않을 시에는 냉동기(300)가 중지되므로 인해 냉방도 중지된다. 따라서, 냉방을 중지하지 않으려면, 열방출라인(420)상의 열방출순환펌프(421)를 가동시켜 온수를 온수측 공급라인(732)으로 공급하여 폐수열회수기(500)에서, 폐수에 열에너지를 공급받아 저온의 온수로서 응축부(320)로 순환됨으로써 냉방이 원활히 이루어지게 되는 특징이 있다.In the cooling system 100 configured as described above, the cooling stop valves 711 and 721 on the supply line 710 and the recovery line 720 at the time of cooling are locked, and the use valve 312 at the time of cooling on the cooling water line 311. As the state 313 is opened, the cooling water of the cooling water line 311 is circulated to the air conditioner and the fan coil 200 to cool the air. In addition, the heat energy exchanged in the refrigerator 300 is transferred to the hot water passing through the condensation unit 320 through the hot water circulation line 321, and also stops cooling because the freezer 300 is stopped when the hot water is not used. do. Therefore, in order not to stop cooling, the heat dissipation circulation pump 421 on the heat dissipation line 420 is operated to supply hot water to the hot water supply line 732 to supply heat energy to the waste water from the wastewater heat recovery machine 500. It is characterized in that the cooling is smoothly made by being circulated to the condensation unit 320 as a low temperature hot water.

한편, 상기와 같이 구성된 본 발명의 냉방시스템(100)은 가정용으로도 적용될 수도 있으나, 호텔이나 콘도, 중앙제어식 냉난방시스템이 적용되는 아파트 등과 같은 건물에 적용됨이 바람직하다.On the other hand, the cooling system 100 of the present invention configured as described above may be applied to a home, but is preferably applied to a building such as a hotel, a condo, an apartment to which a centrally controlled air conditioning system is applied.

이하, 상기와 같이 구성된 본 발명에 따른 냉각탑 및 실외기가 없는 냉방시스템의 작동을 설명한다.Hereinafter, the operation of the cooling tower and the outdoor unit without the cooling system according to the present invention configured as described above.

먼저, 냉방시스템(100)이 작동되면 각 라인상에 설치된 펌프가 작동되되, 냉각수라인(311)과 온수순환라인(321)상의 순환펌프(314)(322)는 항시 작동되고, 냉수공급라인(730)과 열방출라인(420)상의 부스터펌프(731)와 열방출순환펌프(421)는 선택적으로 작동되며, 이의 작동은 냉방시스템(100)에 구성된 콘트롤러에 의해 제어된다.First, when the cooling system 100 is operated, the pumps installed on each line are operated, and the circulation pumps 314 and 322 on the cooling water line 311 and the hot water circulation line 321 are always operated, and the cold water supply line ( 730 and the booster pump 731 and the heat release circulation pump 421 on the heat dissipation line 420 are selectively operated, the operation of which is controlled by a controller configured in the cooling system (100).

따라서, 폐회로의 냉각수라인(311)을 유동하는 냉각수가 냉동기(300)의 증발부(310)를 지나면서 응축부(320)를 지나는 저온의 온수와 열교환되어 열을 빼앗김 으로써 저온화되고, 이 저온의 냉각수는 공조기 및 팬코일(200)로 공급되어 실내공기와 열교환되면서 실내의 온도를 낮추게 된다.Therefore, the cooling water flowing in the cooling water line 311 of the closed circuit passes through the evaporator 310 of the refrigerator 300 and heat exchanges with the hot water of the low temperature passing through the condensation unit 320 to deprive heat, thereby reducing the temperature. Cooling water is supplied to the air conditioner and the fan coil 200 to heat the indoor air while lowering the temperature of the room.

그리고, 실내공기와 열교환되어 다시 고온화된 냉각수는 증발부(310)로 유입되어 전술한 바와 같이 열교환되고, 증발부(310)를 지나는 고온의 냉각수로부터 열을 빼앗은 응축부(320)의 냉수는 고온화된 온수로서 온수탱크(400)로 유입되어 저장된다.In addition, the coolant heat exchanged with the indoor air and heated again to the high temperature flows into the evaporator 310 and is heat-exchanged as described above, and the cold water of the condensation unit 320 that takes heat from the high-temperature coolant passing through the evaporator 310 becomes hot. As the hot water is introduced into the hot water tank 400 and stored.

이와 같은 상태에서 물 사용공간(600)의 온수를 개방시키면, 온수탱크(400)의 탱크압으로 인해 온수탱크(400)에 저장된 온수가 물 사용공간(600)을 통해 토출되어 사용되고, 사용된 온수의 폐수는 물 사용공간(600)에 연결된 방류라인(510)으로 방류된다.When the hot water in the water use space 600 is opened in such a state, hot water stored in the hot water tank 400 is discharged and used through the water use space 600 due to the tank pressure of the hot water tank 400, and used hot water. Wastewater is discharged to the discharge line 510 connected to the water using space 600.

그리고, 물 사용공간(600)을 통한 온수의 토출이 중지된 경우는, 순환하는 온수에 의해 온수탱크(400)의 온도가 계속해서 상승됨으로써 이의 온도를 감지하여 온수탱크(400)에 설정된 온도(대략 50℃ 정도) 이상으로 상승되면, 콘트롤러에 의해 열방출라인(420)상의 열방출순환펌프(421)가 작동하여 저장된 온수를 열방출라인(420)을 통해 폐수열회수기(500)측으로 강제 순환시킨다.In addition, when the discharge of hot water through the water use space 600 is stopped, the temperature of the hot water tank 400 is continuously increased by the circulating hot water to detect the temperature thereof and to set the temperature of the hot water tank 400. About 50 ° C.), the heat release circulation pump 421 on the heat release line 420 is operated by the controller to forcibly circulate the stored hot water through the heat release line 420 to the wastewater heat recovery unit 500. .

이와 같이 폐수열회수기(500)로 공급된 온수는 폐수열회수기(500)에서 열을 빼앗아 저온온수 상태로 응축부(320)로 공급되는 일측의 온수순환라인(321)으로 공급된다.As such, the hot water supplied to the wastewater heat recovery unit 500 is supplied to the hot water circulation line 321 of one side, which takes heat from the wastewater heat recovery unit 500 and is supplied to the condensation unit 320 in a low temperature hot water state.

응축부(320)를 통해 일측의 온수순환라인(321)으로 공급된 온수는 응축부(320)를 지나면서 증발부(310)를 지나는 고온의 냉각수로부터 열을 빼앗아 고온 화된 다음 온수탱크(400)로 재차 유입되어 저장된다.The hot water supplied to the hot water circulation line 321 on one side through the condensation unit 320 takes heat from the high temperature cooling water passing through the evaporator 310 while passing through the condensation unit 320 to be heated to a high temperature, and then to the hot water tank 400. It is introduced again and stored.

그리고, 방류라인(510)을 통해 방류되는 온수는 폐수열회수기(500)를 지나면서 열을 빼앗겨 저온상태로 방류되고, 이와 같이 방류된 물은 종말처리장 또는 다른 에너지원으로 사용될 수 있고, 폐수열회수기(500)에서 회수된 열은 난방장치 등에 사용될 수도 있다.Then, the hot water discharged through the discharge line 510 is deprived of heat while passing through the wastewater heat recovery unit 500, and discharged to a low temperature state, and the discharged water may be used as an end treatment plant or another energy source, and the wastewater heat recovery unit ( Heat recovered at 500 may be used for a heating device or the like.

또한, 물 사용공간(600)에는 온수 이외에도 저수조탱크(700)에 저장된 냉수가 부스터펌프(731)와 냉수공급라인(730)을 통해 공급된다. 그리고, 상기와 같이 냉수공급라인(730)을 유동하는 냉수는 온수의 사용으로 인해 온수가 부족할 시, 냉수공급라인(730)에서 분기된 온수측 공급라인(732)과 열방출라인(420)을 통해 온수순환라인(321)으로 공급되어 보충된다.In addition, in addition to the hot water, the cold water stored in the water storage tank 700 is supplied to the water using space 600 through the booster pump 731 and the cold water supply line 730. And, the cold water flowing in the cold water supply line 730 as described above, when the hot water is insufficient due to the use of hot water, the hot water side supply line 732 and the heat discharge line 420 branched from the cold water supply line 730 It is supplied to the hot water circulation line 321 through.

이때, 부스터펌프(731)의 작동시는 열방출라인(420)상의 열방출순환펌프(421)가 작동 정지된 상태가 되고, 열방출라인(420)상의 열방출순환펌프(421)가 작동될 시는 부스터펌프(731)의 작동이 정지된 상태가 된다.At this time, when the booster pump 731 is operated, the heat dissipation circulation pump 421 on the heat dissipation line 420 is stopped, and the heat dissipation circulation pump 421 on the heat dissipation line 420 is operated. At the time, the operation of the booster pump 731 is stopped.

그리고, 저수조탱크(700)는 냉방시 중지밸브(711)(721)가 개방된 공급라인(710)과 회수라인(720)을 통해 냉각수라인(311)에 냉수를 보충할 수 있다.In addition, the reservoir tank 700 may replenish the cold water to the cooling water line 311 through the supply line 710 and the recovery line 720 in which the stop valves 711 and 721 are opened during cooling.

한편, 상기와 같이 작동되는 냉방시스템(100)은 냉방시, 공급라인(710)과 회수라인(720)상의 냉방시 중지밸브(711)(721)는 잠그고, 냉각수라인(311)상의 냉방시 사용밸브(312)(313)를 개방시킨 상태로서, 공조기 및 팬코일(200)에 냉각수라인(311)의 냉각수가 순환하여 냉방이 이루어진다. 이때, 냉동기(300)에서 열교환된 열에너지는 온수순환라인(321)을 통해 응축부(320)를 지나는 온수로 전달되며, 또 한 온수를 사용하지 않을 시에는 냉동기(300)가 중지되므로 인해 냉방도 중지된다. 따라서, 냉방을 중지하지 않으려면, 열방출라인(420)상의 열방출순환펌프(421)를 가동시켜 온수를 온수측 공급라인(732)으로 공급하여 폐수열회수기(500)에서 폐수에 열에너지를 공급하여 저온의 온수로서 응축부(320)로 순환되므로 냉방은 원활히 이루어지게 된다.On the other hand, the cooling system 100 operated as described above when the cooling, cooling stop valves 711, 721 on the supply line 710 and the recovery line 720 is locked, and used for cooling on the cooling water line 311. As the valves 312 and 313 are opened, the cooling water of the cooling water line 311 is circulated to the air conditioner and the fan coil 200 to cool the air. At this time, the heat energy heat exchanged in the refrigerator 300 is transferred to the hot water passing through the condensation unit 320 through the hot water circulation line 321, and also because the freezer 300 is stopped when the hot water is not used. Is stopped. Therefore, in order not to stop cooling, the heat discharge circulation pump 421 on the heat discharge line 420 is operated to supply hot water to the hot water supply line 732 to supply heat energy to the waste water from the waste water heat recovery machine 500. Since the cold water is circulated to the condensation unit 320, cooling is smoothly performed.

따라서, 기존의 실외기에 설치되어 외기와 열교환되던 응축부(320)를 실내기에 구성함과 아울러 증발부(310)를 지나는 냉각수와 열교환되게 함으로써 실외기나 냉각탑을 없앨 수 있게 된다.Therefore, the outdoor unit or the cooling tower can be eliminated by configuring the condensing unit 320 installed in the existing outdoor unit and heat-exchanging with the outdoor unit, and heat-exchanging with the cooling water passing through the evaporator 310.

이상에서 설명한 바와 같이, 본 발명의 냉각탑 및 실외기가 없는 냉방시스템에 따르면, 기존의 실외기에 설치되던 응축부를 실내기에 설치하여 증발부와 열교환되게 구성함으로써 별도로 설치되던 실외기나 냉각탑을 없애 실외기로 인한 환경공해를 해소하고, 설치공간의 제약을 해소하는 장점이 있다.As described above, according to the cooling system without the cooling tower and the outdoor unit of the present invention, the condensation unit installed in the existing outdoor unit is installed in the indoor unit and configured to exchange heat with the evaporator, thereby eliminating the outdoor unit or cooling tower installed separately, resulting in the environment caused by the outdoor unit. There is an advantage of eliminating pollution and eliminating constraints on installation space.
