지열히트펌프를 이용한 모듈멀티형 냉난방시스템{Module Multi Type Air Conditioning and Heating System using Geothermal Heat Pump}Modular Multi Type Air Conditioning and Heating System using Geothermal Heat Pump

본 발명은 지열히트펌프를 이용한 냉난방시스템에 관한 것으로서, 특히 복수 대의 히트펌프들을 이용하여 다양한 모드로 운전하며 또한 시스템 효율(COP; coefficient of performance)을 향상시킬 수 있게 구성한 것이다.The present invention relates to a cooling and heating system using a geothermal heat pump, and in particular, is configured to operate in various modes using a plurality of heat pumps and to improve the system efficiency (COP).

종래의 지열히트펌프는 실내의 냉난방을 위한 냉난방시스템과 급탕을 위한 급탕시스템이 별개로 구성되어 독립적으로 운전되었다.In the conventional geothermal heat pump, the air-conditioning system for heating and cooling indoors and the hot-water supply system for hot water are separately operated.

따라서 어느 한 지열히트펌프에 고장이 발생할 경우 다른 지열히트펌프로 보완할 수 없으며, 해당하는 운전모드는 정지하게 된다는 단점이 있다.Therefore, when one of the geothermal heat pumps is broken, it cannot be supplemented with another geothermal heat pump, and the corresponding operation mode is stopped.

도면에서 도 1은 지열히트펌프를 이용한 냉난방시스템을 나타낸 개념도이고, 도 2는 지열히트펌프를 이용한 급탕시스템을 나타낸 개념도이다.1 is a conceptual diagram showing a cooling and heating system using a geothermal heat pump, Figure 2 is a conceptual diagram showing a hot water supply system using a geothermal heat pump.

도 1에 도시된 바와 같이, 냉난방시스템(10)은 제1히트펌프(11)와 제2히트펌프(12)를 포함하며, 제1히트펌프(11)와 제2히트펌프(12)는 각각 제1열교환기(21)와 제2열교환기(22), 압축기(13), 팽창밸브(14), 액분리기(15) 및 사방변(16)을 구비한다. 여기에서 제1히트펌프(11)의 제1열교환기(21)와 제2히트펌프(12)의 제1열교환기(21)는 실내로 순환하는 열전달매체와 열교환하며, 제1히트펌프(11)의 제2열교환기(22)와 제2히트펌프(12)의 제2열교환기(22)는 지중에 매설된 지열열교환기(18)로 순환하는 열전달매체와 열교환한다. As shown in FIG. 1, the air conditioning system 10 includes a first heat pump 11 and a second heat pump 12, and the first heat pump 11 and the second heat pump 12 are respectively. The first heat exchanger 21, the second heat exchanger 22, the compressor 13, the expansion valve 14, the liquid separator 15, and the four sides 16 are provided. Here, the first heat exchanger 21 of the first heat pump 11 and the first heat exchanger 21 of the second heat pump 12 exchange heat with a heat transfer medium circulating in the room, and the first heat pump 11 The second heat exchanger (22) and the second heat exchanger (22) of the second heat pump (12) exchange heat with the heat transfer medium circulated to the geothermal heat exchanger (18) embedded in the ground.

여기에서 냉난방시스템(10)이 냉방모드로 운전될 경우 제1히트펌프(11) 및 제2히트펌프(12)의 냉매는 제2열교환기(22)에서 팽창밸브(14), 제1열교환기(21), 사방변(16), 액분리기(15), 압축기(13), 사방변(16) 및 제2열교환기(22)의 경로로 순환하며, 냉매의 열을 제2열교환기(22)에서 방출하고, 제1열교환기(21)에서 흡열한다. 따라서 실내로 순환하는 열전달매체는 제1열교환기(21)에서 열을 방출하게 되어 실내를 시원하게 냉방한다. 반면에 제2열교환기(22)에서 방열된 열은 지열열교환기(18)로 순환하는 열전달매체에 전달되고, 가열된 열전달매체는 지중에서 열을 방출한다.Here, when the cooling and heating system 10 is operated in the cooling mode, the refrigerant of the first heat pump 11 and the second heat pump 12 is expanded in the second heat exchanger 22 to the expansion valve 14 and the first heat exchanger. (21), the four sides (16), the liquid separator (15), the compressor (13), the four sides (16) and the second heat exchanger 22, the circulation of the heat of the refrigerant to the second heat exchanger (22) ) And endothermic in the first heat exchanger (21). Therefore, the heat transfer medium circulating in the room releases heat from the first heat exchanger 21 to cool the room coolly. On the other hand, the heat radiated from the second heat exchanger 22 is transferred to the heat transfer medium circulating to the geothermal heat exchanger 18, and the heated heat transfer medium releases heat from the ground.

반대로, 냉난방시스템(10)이 난방모드로 운전될 경우 제1히트펌프(11) 및 제2히트펌프(12)의 냉매는 제2열교환기(22)에서 사방변(16), 액분리기(15), 압축기(13), 사방변(16), 제1열교환기(21), 팽창밸브(14) 및 제2열교환기(22)의 경로로 순환하며, 냉매의 열을 제1열교환기(21)에서 방출하고, 제2열교환기(22)에서 흡열한다. 따라서 실내로 순환하는 열전달매체는 제1열교환기(21)에서 흡열하여 실내를 따뜻하게 난방한다. 반면에 냉매는 제2열교환기(22)에서 흡열하게 되는데, 지열열교환기(18)로 순환하는 열전달매체는 지중에서 열을 흡열하고 제2열교환기(22)에서 냉매로 열을 전달한다.On the contrary, when the cooling and heating system 10 is operated in the heating mode, the refrigerant of the first heat pump 11 and the second heat pump 12 is discharged from the four sides of the second heat exchanger 22 and the liquid separator 15. ), The compressor 13, the four sides 16, the first heat exchanger 21, the expansion valve 14, and the second heat exchanger 22 circulate through the paths of the refrigerant, and the first heat exchanger 21. ) And endothermic at the second heat exchanger (22). Therefore, the heat transfer medium circulating in the room is endothermic in the first heat exchanger 21 to heat the room warmly. On the other hand, the refrigerant is endothermic in the second heat exchanger 22, the heat transfer medium circulating in the geothermal heat exchanger 18 absorbs heat in the ground and transfers heat from the second heat exchanger 22 to the refrigerant.

이와 같은 냉난방시스템은 아래에서 설명하는 급탕시스템과 별개의 것으로 운전된다.Such a heating and cooling system is operated separately from the hot water supply system described below.

아래에서는 도 2에 도시된 급탕시스템에 대해 설명한다.Hereinafter, the hot water supply system shown in FIG. 2 will be described.

도 2에 도시된 바와 같이, 급탕시스템(30)은 히트펌프(31)를 포함한다. 그리고 급탕용 열교환기(32)의 열전달매체가 히트펌프(31)의 제1열교환기(21)에서 흡열하고, 급탕탱크(33)의 물이 급탕용 열교환기(32)에서 흡열하며, 히트펌프(31)의 제2열교환기(22)와 지중에 매설된 지열열교환기(34)를 순환하는 열전달매체는 지열열교환기(34)에서 흡열한다.As shown in FIG. 2, the hot water supply system 30 includes a heat pump 31. The heat transfer medium of the hot water supply heat exchanger 32 absorbs heat from the first heat exchanger 21 of the heat pump 31, and the water of the hot water supply tank 33 absorbs heat from the hot water heat exchanger 32. The heat transfer medium circulating between the second heat exchanger 22 and the geothermal heat exchanger 34 embedded in the ground endotherm by the geothermal heat exchanger 34.

따라서 급탕시스템(30)이 작동하면 지열열교환기(34)의 열전달매체가 지중에서 가열되고, 가열된 열전달매체는 히트펌프(31)의 제2열교환기(22)에서 냉매로 열을 전달하며, 히트펌프(31)의 제1열교환기(21)에서 냉매는 열을 급탕용 열교환기(32)의 열전달매체로 열을 전달한다. 그러면 급탕탱크(33)의 물이 급탕용 열교환기(32)를 순환하면서 냉매의 열을 흡열한 후 급탕탱크(33)로 유입되어 급탕수의 온도를 상승시킨다.Therefore, when the hot water supply system 30 operates, the heat transfer medium of the geothermal heat exchanger 34 is heated in the ground, and the heated heat transfer medium transfers heat from the second heat exchanger 22 of the heat pump 31 to the refrigerant. In the first heat exchanger 21 of the heat pump 31, the refrigerant transfers heat to the heat transfer medium of the hot water heat exchanger 32. Then, the water in the hot water tank 33 circulates the hot water heat exchanger 32 to absorb heat of the refrigerant, and then flows into the hot water tank 33 to increase the temperature of the hot water.

이와 같이 구성된 냉난방시스템과 급탕시스템은 별개의 구성으로서 상호 유기적인 결합관계가 전혀 이루어지지 않는다.The heating and heating system and the hot water supply system configured as described above are separate components and do not have any organic coupling relationship.

따라서 어느 한 쪽의 시스템이 고장일 경우 시스템에 해당하는 운전모드의 작동이 어려워지는 문제점이 있다.Therefore, when one of the systems is broken, there is a problem that the operation of the operation mode corresponding to the system becomes difficult.

또한, 냉방 및 난방 시에 열전달매체를 통해 열을 지중으로 방출함에 따른 에너지손실이 크다는 단점이 있다.
In addition, there is a disadvantage that the energy loss due to the release of heat to the ground through the heat transfer medium during cooling and heating.

본 발명은 앞에서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 냉방, 난방, 급탕의 운전모드가 모두 이루어질 수 있게 구성된 모듈멀티형 냉난방시스템을 제공하는 데 그 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, an object of the present invention is to provide a modular multi-cooling heating system configured to be made in the operation mode of cooling, heating, hot water supply.

In addition, the present invention can be used for heating and hot water by recycling the heat discarded to the basement in the cooling operation mode, the module multi-type air-conditioning configured to recover and cool the cooling heat discarded to the basement in the heating or hot water operation mode The purpose is to provide a system.

도 3에 도시된 바와 같이, 모듈멀티형 냉난방시스템(100)은 2대 이상(도면 상에는 3대)의 히트펌프(110)를 구비하며, 각 히트펌프(110)의 제2열교환기(112)는 지중에 매설된 지열열교환기(131)와 연결되어 제2열전달매체가 제2열교환기(112)와 지열열교환기(131)를 순환하면서 열을 전달한다. 그리고 각 히트펌프(110)의 제1열교환기(111)는 제1실내(121)에 장착된 냉난방기인 팬코일유닛(FCU)(123)과 급탕용 열교환기(140)로 병렬로 연결되어 제1열전달매체가 순환하면서 열을 전달한다.As shown in FIG. 3, the modular multi-cooling heating system 100 includes two or more (three on the drawings) heat pumps 110, and the second heat exchanger 112 of each heat pump 110 is provided. It is connected to the geothermal heat exchanger 131 embedded in the ground and the second heat transfer medium circulates through the second heat exchanger 112 and the geothermal heat exchanger 131 to transfer heat. In addition, the first heat exchanger 111 of each heat pump 110 is connected in parallel to the fan coil unit (FCU) 123 and the hot water heat exchanger (140), which are air conditioners installed in the first chamber (121). 1 Heat transfer medium circulates and transfers heat.

여기에서 각 히트펌프(110)는 앞에서 설명한 바와 같이, 난방 운전모드와 냉방 운전모드에 따라 냉매가 사방변(116)을 통해 반대방향으로 순환하면서 지열을 팬코일유닛(123) 또는 급탕용 열교환기(140)로 전달하거나 반대로 팬코일유닛(123)의 열을 지중으로 방출한다.Here, each of the heat pumps 110, as described above, the refrigerant is circulated in the opposite direction through the four sides 116 according to the heating operation mode and the cooling operation mode geothermal heat to the fan coil unit 123 or the hot water heat exchanger Transfer to 140 or vice versa to release the heat of the fan coil unit 123 to the ground.

아래에서는 각 운전모드에 따른 작동관계를 도면을 참조하여 설명한다.Hereinafter, an operation relationship according to each operation mode will be described with reference to the drawings.

도 4에 도시된 바와 같이, 3대의 히트펌프(110)를 이용하여 제1실내(121)를 냉방할 경우에, 히트펌프(110)의 냉매는 압축기(113), 사방변(116), 제2열교환기(112), 팽창밸브(114), 제1열교환기(111), 사방변(116), 액분리기(115), 압축기(113)의 순서로 순환하며, 제2열교환기(112)에서는 냉매에서 흡열할 열을 지열열교환기(131)로 연장된 제2순환라인(130)을 따라 순환하는 제2열전달매체로 전달하고, 제2열전달매체는 지열열교환기(131)에서 열을 지중으로 방열한다.As shown in FIG. 4, when the first indoor 121 is cooled by using three heat pumps 110, the refrigerant of the heat pump 110 may be the compressor 113, the four sides 116, and the first refrigerant 121. The second heat exchanger 112, the expansion valve 114, the first heat exchanger 111, the four sides 116, the liquid separator 115, the compressor 113 in the order of the second heat exchanger 112 In the heat transfer to the second heat transfer medium circulating along the second circulation line 130 extending to the geothermal heat exchanger 131 to the endothermic heat exchanger in the refrigerant, the second heat transfer medium is ground heat from the geothermal heat exchanger (131) Heat dissipation

한편, 각 히트펌프(110)의 제1열교환기(111)에서 냉매는 열을 흡열한다. 즉 팬코일유닛(123)으로 순환하는 제1열전달매체의 열을 흡열한 후에 제2열교환기(112)에서 방열한다. 이와 같이 팬코일유닛(123)으로 연장된 제1순환라인(120)을 따라 순환하는 제1열전달매체의 열을 냉매가 흡열함으로써, 팬코일유닛(123)은 제1실내(121)의 열을 흡열하게 되어 냉방이 이루어진다.Meanwhile, the refrigerant absorbs heat in the first heat exchanger 111 of each heat pump 110. That is, after absorbing heat of the first heat transfer medium circulated to the fan coil unit 123, the second heat exchanger 112 radiates heat. In this way, the refrigerant absorbs heat of the first heat transfer medium circulating along the first circulation line 120 extending to the fan coil unit 123, so that the fan coil unit 123 removes heat from the first chamber 121. Endothermic cooling is achieved.

여기에서 제1열교환기(111)에는 팬코일유닛(123)들과 급탕용 열교환기(140)가 병렬로 연결된 제1순환라인(120)의 구조에서 팬코일유닛(123)들로 연장된 제1순환라인(120)에 장착된 제1밸브(201)를 개방하고, 급탕용 열교환기(140)로 연장된 제1순환라인(120)에 장착된 제2밸브(202)와 제3밸브(203)를 폐쇄함으로써, 냉방 운전이 가능하다.The first heat exchanger 111 extends to the fan coil units 123 in the structure of the first circulation line 120 in which the fan coil units 123 and the hot water heat exchanger 140 are connected in parallel. The first valve 201 mounted on the first circulation line 120 is opened, and the second valve 202 and the third valve mounted on the first circulation line 120 extending to the hot water heat exchanger 140 ( By closing 203, cooling operation is possible.

제1밸브(201)를 개방하고 제2밸브(202)를 폐쇄함으로써, 제1순환라인(120)을 따라 순환하는 제1열전달매체가 병렬로 연결된 각 히트펌프(110)의 제1열교환기(111)들을 거쳐 팬코일유닛(123)들로 순환한다.By opening the first valve 201 and closing the second valve 202, the first heat exchanger of each heat pump 110 connected in parallel with the first heat transfer medium circulating along the first circulation line 120 ( Through the 111, the fan coil unit 123 is circulated.

아래에서는 냉방과 급탕의 운전모드에 대해 도 5를 참조하여 설명한다.Hereinafter, an operation mode of cooling and hot water supply will be described with reference to FIG. 5.

도 5에 도시된 바와 같이, 제2열교환기(112)를 순환하는 제2열전달매체가 지열열교환기(131)로 순환하지 않고 급탕용 열교환기(140)로 순환하도록 제2열교환기(112)와 지열열교환기(131)를 연결하는 제2순환라인(130)에는 2개의 제1분기관(151)이 분기되어 급탕용 열교환기(140)로 연장된다. 따라서 제2열교환기(112)를 순환하는 제2열전달매체는 급탕용 열교환기(140)로 순환할 수 있다. 이와 같이 제2열전달매체가 급탕용 열교환기(140)로 순환하도록 2개의 제1분기관(151)에는 각 제4밸브(204)와 제5밸브(205)가 장착되며, 제2순환라인(130)에 있어서 제1분기관(151)이 분기된 지점 후방에는 제2열전달매체가 지열열교환기(131)로 순환하지 않게 차단하는 제6밸브(206)와 제7밸브(207)가 장착된다. 따라서 제6밸브(206)와 제7밸브(207)를 폐쇄하고 제4밸브(204)와 제5밸브(205)를 개방하면 제2열교환기(112)를 순환하는 제2열전달매체는 지열열교환기(131)로 순환하지 않고 제1분기관(151)을 통해 급탕용 열교환기(140)로 순환한다. As shown in FIG. 5, the second heat exchanger 112 circulates the second heat transfer medium circulating the second heat exchanger 112 to the hot water heat exchanger 140 without circulating to the geothermal heat exchanger 131. Two first branch pipes 151 are branched to the second circulation line 130 connecting the geothermal heat exchanger 131 to the hot water heat exchanger 140. Therefore, the second heat transfer medium circulating the second heat exchanger 112 may be circulated to the hot water heat exchanger 140. As such, each of the four first valves 204 and the fifth valve 205 is mounted on the two first branch pipes 151 to circulate the second heat transfer medium to the hot water heat exchanger 140. In the 130, the sixth valve 206 and the seventh valve 207 are installed behind the branched branch of the first branch pipe 151 to prevent the second heat transfer medium from circulating to the geothermal heat exchanger 131. . Therefore, when the sixth valve 206 and the seventh valve 207 are closed and the fourth valve 204 and the fifth valve 205 are opened, the second heat transfer medium circulating the second heat exchanger 112 is geothermal heat exchange. The water is circulated to the heat exchanger for hot water supply through the first branch pipe 151 without being circulated to the gas 131.

따라서 냉매 운전모드로 작동하면서, 제2열전달매체는 제2열교환기(112)에서 흡열하고 제2열전달매체는 제1분기관(151)을 통해 급탕용 열교환기(140)로 순환하면서 급탕용 열교환기(140)를 순환하는 급탕수를 가열한다. 가열된 급탕수는 급탕탱크(141)에 저장되어 급탕을 공급할 수 있게 된다.Therefore, while operating in the refrigerant operation mode, the second heat transfer medium is endothermic in the second heat exchanger 112 and the second heat transfer medium is circulated through the first branch pipe 151 to the hot water heat exchanger 140, the heat exchange for hot water supply The hot water circulating in the group 140 is heated. The heated hot water is stored in the hot water tank 141 to supply hot water.

이와 같이 냉방 운전모드 시에는 열을 지하로 방열하였으나, 냉방 운전모드와 급탕 운전모드를 병행할 경우에 실내를 냉방하면서 버려졌던 열을 이용하여 급탕수를 생산할 수 있다.As such, in the cooling operation mode, the heat is radiated to the basement, but when the cooling operation mode and the hot water operation mode are combined, the hot water can be produced using the heat that has been discarded while cooling the room.

아래에서는 난방 운전모드로 작동할 경우에 작동관계에 대해 설명한다.The following describes the operation relationship when operating in the heating operation mode.

도 6에 도시된 바와 같이 난방 운전모드로 작동할 경우, 3대의 히트펌프(110)의 냉매는 제2열교환기(112)에서 사방변(116), 액분리기(115), 압축기(113), 사방변(116), 제1열교환기(111), 팽창밸브(114) 및 제2열교환기(112)로 순환하며, 냉매의 열을 제1열교환기(111)에서 방출하고, 제2열교환기(112)에서 흡열한다. 따라서 제1실내(121)로 순환하는 제1열전달매체는 제1열교환기(111)에서 흡열하고 제1실내(121)에서 방열하여 제1실내(121)를 따뜻하게 난방한다. 반면에 냉매는 제2열교환기(112)에서 흡열하게 되는데, 지열열교환기(131)로 순환하는 제2열전달매체는 지중에서 열을 흡열하고 제2열교환기(112)에서 냉매로 열을 전달한다.When operating in the heating operation mode as shown in Figure 6, the refrigerant of the three heat pump 110 is the four sides 116, the liquid separator 115, the compressor 113, in the second heat exchanger (112), Circulates in all directions 116, the first heat exchanger 111, expansion valve 114 and the second heat exchanger 112, and releases the heat of the refrigerant from the first heat exchanger 111, the second heat exchanger Endotherm at 112. Therefore, the first heat transfer medium circulating in the first chamber 121 absorbs heat in the first heat exchanger 111 and radiates heat in the first chamber 121 to warm the first chamber 121. On the other hand, the refrigerant is endothermic in the second heat exchanger 112, the second heat transfer medium circulating in the geothermal heat exchanger 131 absorbs heat in the ground and transfers heat from the second heat exchanger 112 to the refrigerant. .

이와 같이 제1열전달매체와 제2전달매체가 순환하도록 제1밸브(201), 제6밸브(206) 및 제7밸브(207)는 개방되고, 제2밸브(202), 제3밸브(203), 제4밸브(204) 및 제5밸브(205)는 폐쇄된다.
In this way, the first valve 201, the sixth valve 206, and the seventh valve 207 are opened, the second valve 202, and the third valve 203 to circulate the first heat transfer medium and the second transfer medium. ), The fourth valve 204 and the fifth valve 205 are closed.

아래에서는 급탕 운전모드로 작동할 경우에 작동관계에 대해 설명한다.The following describes the operation relationship when operating in the hot water operation mode.

도 7에 보이듯이 3대의 히트펌프(110)가 난방 운전모드로 작동하며, 제1밸브(201), 제4밸브(204), 제5밸브(205)를 폐쇄하고, 제2밸브(202), 제3밸브(203), 제6밸브(206), 제7밸브(207)를 개방한다. 그러면 제1열교환기(111)에서 흡열한 제1열전달매체는 제1실내(121)의 팬코일유닛(123)으로 순환하지 않고 급탕용 열교환기(140)로 순환하면서 급탕용 열교환기(140)를 지나는 급탕수를 가열하게 된다. 가열된 급탕수는 펌프에 의해 급탕탱크(141)에 집수되며 급탕탱크(141)에 집수된 급탕수는 사용자의 필요에 따라 공급된다.
As shown in FIG. 7, three heat pumps 110 operate in a heating operation mode, and close the first valve 201, the fourth valve 204, and the fifth valve 205, and the second valve 202. The third valve 203, the sixth valve 206, and the seventh valve 207 are opened. Then, the first heat transfer medium absorbed by the first heat exchanger 111 is circulated to the hot water heat exchanger 140 without circulating to the fan coil unit 123 of the first room 121 while the hot water heat exchanger 140 It will heat the hot water passing through. The heated hot water is collected in the hot water tank 141 by a pump, and the hot water supplied in the hot water tank 141 is supplied according to a user's needs.

아래에서는 난방 운전모드와 급탕 운전모드를 병행하여 운전하는 작동관계에 대해 설명한다.Hereinafter, an operation relationship of driving the heating operation mode and the hot water operation mode in parallel will be described.

도 8에 보이듯이 3대의 히트펌프(110)는 난방 운전모드로 작동한다. 그리고 제1밸브(201), 제2밸브(202), 제3밸브(203), 제6밸브(206), 제7밸브(207)를 개방하고, 제4밸브(204), 제5밸브(205)를 폐쇄한다. 그러면 제1열교환기(111)에서 흡열한 제1열전달매체는 병렬로 연결된 제1실내(121)의 팬코일유닛(123)과 급탕용 열교환기(140)로 분류되어 각 팬코일유닛(123) 및 급탕용 열교환기(140)를 거친 후 합류하여 제1열교환기(111)로 순환한다.As shown in FIG. 8, the three heat pumps 110 operate in a heating operation mode. The first valve 201, the second valve 202, the third valve 203, the sixth valve 206, and the seventh valve 207 are opened, and the fourth valve 204 and the fifth valve ( 205 is closed. Then, the first heat transfer medium absorbed by the first heat exchanger 111 is classified into a fan coil unit 123 and a hot water heat exchanger 140 in the first chamber 121 connected in parallel to each fan coil unit 123. And after passing through the heat exchanger 140 for hot water to join and circulated to the first heat exchanger (111).

여기에서, 급탕용 열교환기(140) 및 팬코일유닛(123)들을 거친 제1열전달매체가 합류하기 이전에 정유량밸브(143)를 합류지점 전방에 설치한다. 구체적으로 급탕용 열교환기(140)에서 합류지점으로 연장된 배관에 정유량밸브(143)를 설치하여 유량의 평형을 맞춘다.
Here, the constant flow rate valve 143 is installed in front of the confluence point before the first heat transfer medium passing through the hot water supply heat exchanger 140 and the fan coil unit 123 joins. Specifically, a constant flow valve 143 is installed in a pipe extending from the hot water heat exchanger 140 to a confluence point to balance the flow rate.
