Description

순환배관을 이용한 냉온수 공급 시스템{Cold and hot water supply system using circulation piping}Cold and hot water supply system using circulation piping}

본 발명은 냉온수 공급 시스템에 관한 것으로, 보다 자세하게는 냉매를 순환하여 제1, 2 열교환기를 통해 냉수와 온수를 공급하는 냉온수 공급 시스템에 있어서, 제1열교환기를 통해 냉수를 생성하되 열원유입배관과 냉수배출배관 사이에 냉수순환배관을 설치하여 열원수가 제1열교환기를 반복순환 하도록 하고, 제2열교환기를 통해 생성된 온수를 온수통에 저장하되, 상기 온수통에 저장된 온수가 과열되면 저장된 온수를 온수이용장치로 냉각시키도록 한 냉온수 공급 시스템에 관한 것이다.The present invention relates to a cold/hot water supply system, and more particularly, in a cold/hot water supply system that supplies cold water and hot water through first and second heat exchangers by circulating a refrigerant, generating cold water through a first heat exchanger, but generating a heat source inlet pipe and cold water. A cold water circulation pipe is installed between the discharge pipes so that the heat source water repeatedly circulates the first heat exchanger, and the hot water generated through the second heat exchanger is stored in the hot water tank, but when the hot water stored in the hot water tank is overheated, the stored hot water is used. It relates to a hot and cold water supply system to be cooled by a device.

일반적으로 냉온수 공급 시스템은 액체가 기화할 때 주변의 열을 흡수하고, 기체가 다시 액화될 때 주변에 열을 방출하는 성질을 이용한다.In general, a hot/cold water supply system uses the property of absorbing heat from the surroundings when a liquid vaporizes and releasing heat to the surroundings when the gas is liquefied again.

이와 같은 성질은 냉매(Refrigerant)를 통해 이루어질 수 있는데, 냉매는 상술한 바와 같이 기화되면서 주변의 열을 흡수하여 주변을 차게 만들며, 액화되면서 주변에 열을 방출하여 주변을 따듯하게 만든다. 상기 냉매에 속하는 것으로는 암모니아, 염화불화탄소(CFC, 프레온가스), 수소불화탄소(HFC), 수소불화올레핀(HFO) 등이 있다. Such a property can be achieved through a refrigerant. The refrigerant is vaporized as described above and absorbs heat from the surroundings to cool the surroundings, and while liquefied, it releases heat to the surroundings to make the surroundings warm. Examples of the refrigerant include ammonia, chlorofluorocarbon (CFC, freon gas), hydrogen fluorocarbon (HFC), and hydrogen fluoride olefin (HFO).

냉온수 공급 시스템에서는 인위적으로 냉매를 기화시키는데, 팽창밸브 등을 통해 냉매를 저압으로 만든 후 열교환기에서 기화시켜 주변의 열을 흡수하도록 함으로써 주변에 대한 냉각 작용을 하는 것이다. 또한, 기체로 변한 냉매를 다시 인위적으로 액화시키는데, 압축기 등을 통해 냉매를 고압으로 가압하여 열교환기에서 액화시켜 주변에 열을 방출시키도록 함으로써 주변에 대한 가열 작용을 한다.In the cold and hot water supply system, the refrigerant is artificially vaporized. After making the refrigerant to a low pressure through an expansion valve or the like, it vaporizes in a heat exchanger to absorb heat from the surroundings, thereby cooling the surroundings. In addition, the refrigerant converted into gas is artificially liquefied again, and the refrigerant is pressurized to a high pressure through a compressor or the like to liquefy the refrigerant in a heat exchanger to release heat to the surrounding, thereby heating the surroundings.

이러한 냉온수 공급 시스템에 관한 것으로, 대한민국 등록실용신안 제20-0428357호에는 히트펌프용 냉수/온수 발생 시스템이 개시되어 있는데, 이는 압축기와, 증발기, 팽창밸브, 리시버탱크, 응축기로 구성되어 냉기와 온기를 발생시키는 히트펌프 시스템에 있어서, 냉매가스가 고압/고온으로 압축하는 압축기로 공급되어, 상기 압축기로부터 공급된 냉매가스가 열교환되는 제1열교환기로 흘러, 상기 제1열교환기의 냉매가스와 상온수가 열교환 되어 온수탱크에 저장되며, 상기 제1열교환기로부터 공급된 냉매가스가 액화상태로 저장되는 리시버탱크로 흘러, 상기 리시버탱크로부터 공급된 냉매가스가 제1팽창밸브를 통과하면서 팽창된 상태로 증발기로 공급되어 압축기로 순환되는 온수발생수단과; 상기 리시버탱크와 증발기의 사이에서 분기 되어 전자변의 온/오프에 의해 냉매가스가 팽창밸브를 통과하면서 팽창된 상태로 제2열교환기에 공급되어, 상온수가 열교환 되어 냉수탱크에 저장되며, 상기 제2열교환기로부터 공급된 냉매가스가 제2열교환기로 역류 되지 않도록 흐르는 냉수발생수단을 포함하여 구성되는 것을 특징으로 하는 히트펌프용 동시 냉수/온수 발생 시스템에 관한 것이다.Regarding such a cold and hot water supply system, Korean Utility Model No. 20-0428357 discloses a cold/hot water generation system for a heat pump, which consists of a compressor, an evaporator, an expansion valve, a receiver tank, and a condenser. In the heat pump system for generating, refrigerant gas is supplied to a compressor that compresses high pressure/high temperature, and the refrigerant gas supplied from the compressor flows to a first heat exchanger for heat exchange, and the refrigerant gas and room temperature water of the first heat exchanger Heat exchanged and stored in a hot water tank, the refrigerant gas supplied from the first heat exchanger flows into a receiver tank in which the refrigerant gas supplied from the first heat exchanger is stored in a liquefied state, and the refrigerant gas supplied from the receiver tank is expanded while passing through the first expansion valve. Hot water generating means supplied to and circulated to the compressor; Branched between the receiver tank and the evaporator, refrigerant gas is supplied to the second heat exchanger in an expanded state while passing through the expansion valve by the on/off of the electronic valve, and the room temperature water is heat-exchanged and stored in the cold water tank, and the second heat exchange It relates to a simultaneous cold/hot water generating system for a heat pump, characterized in that it comprises a cold water generating means flowing so that the refrigerant gas supplied from the unit does not flow back to the second heat exchanger.

그러나, 상기 종래의 기술은 외부로부터 유입된 상온수가 냉수탱크에 저장되고, 냉수탱크가 순차적으로 설치되어 저장된 물이 열교환기와 교류하여 점차적으로 수온이 내려가는 방식으로써, 냉수탱크를 설치하는데 있어서 설치비용과 설치면적이 지나치게 요구되는 문제점이 있었다.However, the conventional technology is a method in which room temperature water introduced from the outside is stored in a cold water tank, and the cold water tanks are sequentially installed so that the stored water exchanges with the heat exchanger to gradually decrease the water temperature. There was a problem that the installation area was excessively required.

또한, 상기 종래의 기술은 온수탱크 내부의 온도가 과열될 경우 이를 처리하기 위하여 저장된 온수를 방바닥 등 가온을 필요로 하는 곳으로 보내어 온수 온도를 낮추었다. 그러나, 여름 등 온수를 필요로 하지 않을 때에는 온수 흘려보내는 것이 불가하므로 온수의 온도를 낮추는 역할을 수행하지 못하는 문제점이 있었다.In addition, in the conventional technology, when the temperature inside the hot water tank is overheated, the stored hot water is sent to a place that requires heating, such as a room, to reduce the temperature of the hot water. However, when hot water is not required, such as in summer, it is impossible to flow hot water, so there is a problem in that it cannot perform the role of lowering the temperature of hot water.

As described above, the first heat exchanger 210 uses the property of the vaporized refrigerant to absorb heat, and serves to lower the temperature of the heat source water to convert it into cold water. The first heat exchanger 210 may lower the temperature of the heat source water by 3 to 5°C each time the heat source water passes once.

The cold water discharge pipe 240 is divided into a first cold water discharge pipe 242 and a second cold water discharge pipe 246 based on the second automatic check valve 244. A pipe connected to the first heat exchanger 210 based on the second automatic check valve 244 is referred to as a first cold water discharge pipe 242, and a cold water circulation system 200 based on the second automatic check valve 244 ) The pipe connected to the outside is referred to as the second cold water discharge pipe 246.

상기와 같은 구성을 통하여, 본 발명의 열원모터(220)를 통해 열원유입배관(230)을 따라 제1열교환기(210)로 이동된 열원수는, 제1열교환기(210)에서 온도가 하강되어 냉수배출배관(240)을 따라 배출되면서 냉수를 공급할 수 있다.Through the above configuration, the heat source water moved to the first heat exchanger 210 along the heat source inlet pipe 230 through the heat source motor 220 of the present invention, the temperature decreases in the first heat exchanger 210 As it is discharged along the cold water discharge pipe 240, it is possible to supply cold water.

이를 위하여, 본 발명에 따른 순환배관을 이용한 냉온수 공급 시스템은 상기 제1자동체크밸브(234)와 제2자동체크밸브(244)에 연결되어 열원유입배관(230)과 냉수배출배관(240) 사이에 연결되는 냉수순환배관(250)을 포함한다.To this end, the cold and hot water supply system using a circulation pipe according to the present invention is connected to the first automatic check valve 234 and the second automatic check valve 244, and between the heat source inlet pipe 230 and the cold water discharge pipe 240 It includes a cold water circulation pipe 250 connected to.

상기 냉수순환배관(250)은 냉수배출배관(240)과 열원유입배관(230)을 연결하는 배관으로서, 제1열교환기(210)를 통해 온도가 낮아진 열원수를 다시 한번 열원유입배관(230)으로 보냄으로써, 한번 냉각된 열원수가 제1열교환기(210)를 또 다시 통과하여 다시 한번 냉각되도록 하는 역할을 한다.The cold water circulation pipe 250 is a pipe connecting the cold water discharge pipe 240 and the heat source inlet pipe 230, and the heat source water having a lowered temperature through the first heat exchanger 210 is once again a heat source inlet pipe 230. By sending to, the heat source water once cooled passes through the first heat exchanger 210 again and serves to be cooled again.

다시 말해, 상기 냉수순환배관(250)은 악보의 도돌이표에 해당하는 기능을 하는 것으로, 반복되는 순환을 통해열원수가 사용자가 원하는 온도가 될 때까지 반복적으로 순환을 시킴으로써 냉수탱크 등의 추가적인 설비를 필요로 하지 않는 것이다. 그러나, 상기와 같은 구성을 수동으로 진행하기에는 무리가 있으며, 효율적인 냉수의 생산을 위해서는 체계화되고 자동적인 시스템의 구축이 필요할 것이다.In other words, the cold water circulation pipe 250 has a function corresponding to the dodo table of the score, and requires additional facilities such as a cold water tank by repeatedly circulating the heat source water until the temperature desired by the user through repeated circulation. It is not done. However, it is difficult to manually proceed with the above configuration, and it will be necessary to construct a systematic and automatic system for efficient cold water production.

이에, 본 발명에 따른 순환배관을 이용한 냉온수 공급 시스템은 제1열교환기(210)를 거쳐 냉수배출배관(240)을 통해 바로 배출될지 또는 열원수가 냉수순환배관(250)을 순환할지에 대한 여부와, 냉수순환배관(250)을 통해 열원수가 순환하는 횟수를 자동으로 판단하고 작동시키는 구성을 추가로 포함한다.Thus, the cold and hot water supply system using the circulation pipe according to the present invention is to determine whether or not the heat source water is directly discharged through the cold water discharge pipe 240 through the first heat exchanger 210 or whether the heat source water circulates the cold water circulation pipe 250 , It further includes a configuration for automatically determining and operating the number of times the heat source water circulates through the cold water circulation pipe 250.

좀 더 구체적으로 본 발명에 따른 순환배관을 이용한 냉온수 공급 시스템은 상기 제1열원유입배관(232)에 설치되어 열원수의 온도를 측정하는 열원온도측정센서(233)와, 상기 냉수순환배관(250)에 설치되어 냉수순환배관(250)을 흐르는 물의 온도를 측정하는 냉수순환배관온도측정센서(252), 상기 열원온도측정센서(233)로부터 측정된 온도와 냉수순환배관온도측정센서(252)로부터 측정된 온도를 기반으로 사용자가 기설정한 온도에 도달할 때까지 제1, 2자동체크밸브(234, 244)의 작동을 제어하고 냉수순환배관(250)을 반복 순환시키는 컨트롤박스(400)를 더 포함한다.More specifically, the cold and hot water supply system using a circulation pipe according to the present invention includes a heat source temperature measuring sensor 233 installed in the first heat source inlet pipe 232 to measure the temperature of the heat source water, and the cold water circulation pipe 250 ) Installed in the cold water circulation pipe temperature measuring sensor 252 for measuring the temperature of the water flowing through the cold water circulation pipe 250, the temperature measured from the heat source temperature measuring sensor 233 and the cold water circulation pipe temperature measuring sensor 252 Based on the measured temperature, a control box 400 that controls the operation of the first and second automatic check valves 234 and 244 until reaching a preset temperature by the user and repeatedly circulates the cold water circulation pipe 250 is provided. Include more.

상기 열원온도측정센서(233)는 제1열원유입배관(232)에 설치되어 열원수의 온도를 측정한다. 상기 열원온도측정센서(233)를 통해 측정된 측정값은 컨트롤박스(400)로 전송된다.The heat source temperature measuring sensor 233 is installed in the first heat source inlet pipe 232 to measure the temperature of the heat source water. The measured value measured through the heat source temperature measuring sensor 233 is transmitted to the control box 400.

상기 냉수순환배관온도측정센서(252)는 냉수순환배관(250)에 설치되어 냉수순환배관(250) 내부의 물의 온도를 측정한다. 상기 냉수순환배관온도측정센서(252)를 통해 측정된 측정값은 컨트롤박스(400)로 전송된다.The cold water circulation pipe temperature measuring sensor 252 is installed in the cold water circulation pipe 250 to measure the temperature of water in the cold water circulation pipe 250. The measured value measured through the cold water circulation pipe temperature measuring sensor 252 is transmitted to the control box 400.

상기 컨트롤박스(400)는 냉수순환계(200)의 외부에 설치되며, 한편, 냉수순환배관온도측정센서(252)로부터 측정된 온도와 기설정된 온도를 비교하여 제1, 2자동체크밸브(234, 244)의 작동을 제어할 수 있다. 즉, 냉수순환배관온도측정센서(252)로부터 측정된 온도가 기설정된 온도에 도달하면 제2냉수배출배관(246)을 통해 냉수를 배출하고, 냉수순환배관온도측정센서(252)로부터 측정된 온도가 기설정된 온도에 도달하지 않으면, 냉수순환배관(250)을 통해 순환을 계속 반복하는 것이다. The control box 400 is installed outside the cold water circulation system 200, on the other hand, the first and second automatic check valves 234 by comparing the temperature measured from the cold water circulation pipe temperature measuring sensor 252 with a preset temperature. 244) can be controlled. That is, when the temperature measured by the cold water circulation pipe temperature measuring sensor 252 reaches a preset temperature, the cold water is discharged through the second cold water discharge pipe 246, and the temperature measured by the cold water circulation pipe temperature measuring sensor 252 If the temperature does not reach a preset temperature, the circulation is continuously repeated through the cold water circulation pipe 250.

또는, 상기 컨트롤박스(400)는 전송된 측정값을 바탕으로 냉수순환계(200)에서 열원수의 순환이 필요한 횟수를 계산하고, 계산된 결과를 바탕으로 제1, 2 자동체크밸브(234, 244)의 작동을 제어하는 것일 수 있다.Alternatively, the control box 400 calculates the number of times the heat source water needs to be circulated in the cold water circulator 200 based on the transmitted measured value, and based on the calculated result, the first and second automatic check valves 234 and 244 ) May be to control the operation.

이를 좀 더 구체적으로 설명하자면, 상기 컨트롤박스(400)는 열원온도측정센서(233)를 통해 측정된 최초 온도와 사용자가 기설정한 온도의 차이를 계산한다. 또한, 열원온도측정센서(233)에서 측정된 최초 온도와 냉수순환배관온도측정센서(252)에서 측정된 온도의 차이를 계산한다. 이는 제1열교환기(210)를 1회 통과하면서 열원수가 낮아진 온도이다. 다음으로, '열원온도측정센서(233)를 통해 측정된 최초 온도와 사용자가 기설정한 온도의 차이'를 '열원온도측정센서(233)에서 측정된 최초 온도와 냉수순환배관온도측정센서(252)에서 측정된 온도의 차이'로 나눠줌으로써 예상순환횟수를 예측한다.To explain this in more detail, the control box 400 calculates a difference between the initial temperature measured through the heat source temperature measuring sensor 233 and the temperature preset by the user. In addition, the difference between the initial temperature measured by the heat source temperature measuring sensor 233 and the temperature measured by the cold water circulation pipe temperature measuring sensor 252 is calculated. This is the temperature at which the number of heat sources is lowered while passing through the first heat exchanger 210 once. Next, the'difference between the initial temperature measured by the heat source temperature measuring sensor 233 and the temperature preset by the user' is determined from the'initial temperature measured by the heat source temperature measuring sensor 233 and the cold water circulation pipe temperature measuring sensor 252. Predict the expected number of cycles by dividing it by the difference in temperature measured in ).

즉, 예상순환횟수 = (최초측정온도-사용자가 기설정한 온도)/(최초측정온도-제1열교환기를 1회 통과한 후의 측정온도)가 되는 것이다. That is, the expected number of cycles = (initial measurement temperature-temperature preset by the user)/(initial measurement temperature-measurement temperature after passing the first heat exchanger once).

다시 말해, 상기 컨트롤박스(400)는 '열원온도측정센서(233)로부터 측정된 온도와 사용자가 기설정한 온도의 차이값' 및 '열원온도측정센서(233)로부터 측정된 온도와 제1열교환기(210)를 1회 통과한 후의 배관온도측정센서(252)에서 측정된 온도의 차이값'을 바탕으로 예상순환횟수를 결정하는 것을 특징으로 한다.In other words, the control box 400 is'the difference between the temperature measured from the heat source temperature measuring sensor 233 and the temperature preset by the user' and'the temperature measured from the heat source temperature measuring sensor 233 and the first heat exchange. It is characterized in that the estimated number of cycles is determined based on the difference value of the temperature measured by the pipe temperature measuring sensor 252 after passing through the device 210 once.

상기 컨트롤박스(400)는 계산된 결과를 바탕으로 제1, 2자동체크밸브(234, 244)를 제어한다.The control box 400 controls the first and second automatic check valves 234 and 244 based on the calculated result.

상기 제1자동체크밸브(234)는 상기 컨트롤박스(400)에 의해 새로운 열원수의 유입이 필요하다고 판단되면, 제1열원유입배관(232)과 제2열원유입배관(236) 사이를 개방함과 동시에 냉수순환배관(250)과 제2열원유입배관(236) 사이를 폐쇄하고, 상기 컨트롤박스(400)에 의해 냉수의 순환이 계속 필요하다고 판단되면, 냉수순환배관(250)과 제2열원유입배관(236) 사이를 개방함과 동시에 제1열원유입배관(232)과 제2열원유입배관(236) 사이를 폐쇄할 수 있다.The first automatic check valve 234 opens between the first heat source inlet pipe 232 and the second heat source inlet pipe 236 when it is determined that the inflow of new heat source water is necessary by the control box 400 At the same time, the cold water circulation pipe 250 and the second heat source inlet pipe 236 are closed, and if it is determined that circulation of cold water is continuously required by the control box 400, the cold water circulation pipe 250 and the second heat source It is possible to open the space between the inlet pipes 236 and close the space between the first heat source inlet pipe 232 and the second heat source inlet pipe 236.

또한, 상기 제2자동체크밸브(244)는 상기 컨트롤박스(400)에 의해 냉수의 순환이 계속 필요하다고 판단되면, 제1냉수배출배관(242)과 냉수순환배관(250) 사이를 개방함과 동시에 제1냉수배출배관(242)과 제2냉수배출배관(246) 사이를 폐쇄하고, 상기 컨트롤박스에 의해 냉수의 배출이 필요하다고 판단되면, 제1냉수배출배관(242)과 제2냉수배출배관(246) 사이를 개방함과 동시에 제1냉수배출배관(242)과 냉수순환배관(250) 사이를 폐쇄할 수 있다.In addition, the second automatic check valve 244 opens between the first cold water discharge pipe 242 and the cold water circulation pipe 250 when it is determined by the control box 400 that the circulation of cold water is still necessary. At the same time, the first cold water discharge pipe 242 and the second cold water discharge pipe 246 are closed, and when it is determined that cold water discharge is necessary by the control box, the first cold water discharge pipe 242 and the second cold water discharge The pipes 246 may be opened, and at the same time, the first cold water discharge pipe 242 and the cold water circulation pipe 250 may be closed.

다시 말해, 열원수의 최초 유입 시에는 상기 제1자동체크밸브(234)가 제1열원유입배관(232)과 제2열원유입배관(236) 사이를 개방하여 열원수가 제1열교환기(210)로 바로 이동되도록 하고, 제2자동체크밸브(244)는 제1냉수배출배관(242)과 냉수순환배관(250) 사이를 개방한 상태로 대기한다. 이에 따라, 제1열교환기(210)를 통과한 열원수는 바로 배출되지 않고 냉수순환배관(250)으로 이동된다.In other words, when the heat source water first flows in, the first automatic check valve 234 opens between the first heat source inlet pipe 232 and the second heat source inlet pipe 236 so that the heat source water is the first heat exchanger 210. And the second automatic check valve 244 waits with the first cold water discharge pipe 242 and the cold water circulation pipe 250 open. Accordingly, the heat source water that has passed through the first heat exchanger 210 is not immediately discharged and is moved to the cold water circulation pipe 250.

냉수순환배관(250) 내부에 열원수가 가득차게 되어, 열원수의 유입이 완료되면, 제1자동체크밸브(234)는 냉수순환배관(250)과 제2열원유입배관(236) 사이를 개방함과 동시에 제1열원유입배관(232)과 제2열원유입배관(236) 사이를 폐쇄하는 상태로 전환되며, 더이상 열원모터(220)로부터 유입되는 물을 받아들이지 않고 냉수순환배관(250)이 폐쇄된 계를 이루도록 한다.When the heat source water is filled in the cold water circulation pipe 250 and the inflow of the heat source water is completed, the first automatic check valve 234 opens between the cold water circulation pipe 250 and the second heat source inflow pipe 236 At the same time, the first heat source inlet pipe 232 and the second heat source inlet pipe 236 are switched to a closed state, and the cold water circulation pipe 250 is closed without receiving water flowing from the heat source motor 220 anymore. Make the system come true.

상기 냉수순환배관(250)에는 냉수통(256)이 추가적으로 설치될 수도 있다. 냉수통(256)이 설치된 경우 더 많은 양의 물을 저장하고 순환시킬 수 있을 것이다.A cold water tank 256 may be additionally installed in the cold water circulation pipe 250. If the cold water tank 256 is installed, it will be possible to store and circulate a larger amount of water.

상기 냉수순환배관온도측정센서(252)는 냉수통(256)의 내부에 설치되어도 무방하다. 냉수통(256) 역시 냉수순환배관(250)의 일부 구성이기 때문에 냉수순환배관온도측정센서(252)가 설치될 수 있다. 상기 냉수순환배관온도측정센서(252)는냉수통(256) 내부의 물의 온도를 측정할 수 있다.The cold water circulation pipe temperature measuring sensor 252 may be installed inside the cold water container 256. Since the cold water tank 256 is also a part of the cold water circulation pipe 250, the cold water circulation pipe temperature measuring sensor 252 may be installed. The cold water circulation pipe temperature measurement sensor 252 may measure the temperature of the water inside the cold water tank 256.

다목적 냉수 활용이 필요할 경우, 상기 냉수통(256)에는 팬코일유닛(260)이 연결될 수 있다. 상기 팬코일유닛(260)은 냉수통(256)의 냉수를 이용해 냉방에 사용한다. 상기 팬코일유닛(260)에 냉수를 보내기 위하여 상기 냉수통(256)의 일측에는 냉수통모터(262)가 설치될 수 있으며, 상기 냉수통모터(262)에는 팬코일유닛배관(264)이 연장되어 팬코일유닛(260)으로 연결된다. 사용자는 컨트롤박스(400)를 이용해 냉수통모터(262)를 작동시킬 수 있으며, 냉수통모터(262)가 작동되면 팬코일유닛배관(264)을 따라 냉수가 이동되어 팬코일유닛(260)에 냉수가 전달되고, 상기 팬코일유닛(260)은 이를 통해 냉방기능을 할 수 있을 것이다.When it is necessary to use multi-purpose cold water, a fan coil unit 260 may be connected to the cold water container 256. The fan coil unit 260 is used for cooling by using the cold water of the cold water container 256. In order to send cold water to the fan coil unit 260, a cold water bottle motor 262 may be installed at one side of the cold water bottle 256, and a fan coil unit piping 264 is extended to the cold water bottle motor 262. Is connected to the fan coil unit 260. The user can operate the cold water bottle motor 262 using the control box 400, and when the cold water bottle motor 262 is operated, cold water is moved along the fan coil unit piping 264 to the fan coil unit 260. Cold water is delivered, and the fan coil unit 260 may perform a cooling function through this.

한편, 상기 냉수순환배관(250)에는 냉수순환배관모터(254)가 설치된다. 이는 제1자동체크밸브(234)에 의해 제1열원유입배관(232)과 제2열원유입배관(236) 사이가 폐쇄되면서 열원모터(220)의 동력이 차단되는바 냉수순환배관(250)에 새로운 동력을 전달하기 위함이다. 냉수순환배관(250)은 냉수순환배관모터(254)의 동력에 의해 내부의 열원수가 순환될 수 있으며, 상기 냉수순환배관모터(254)의 작동은 컨트롤박스(400)에 의해 제어된다.Meanwhile, a cold water circulation pipe motor 254 is installed in the cold water circulation pipe 250. This is because the power of the heat source motor 220 is cut off as the first heat source inlet pipe 232 and the second heat source inlet pipe 236 are closed by the first automatic check valve 234, and the cold water circulation pipe 250 It is to transmit new power. The cold water circulation pipe 250 may circulate internal heat source water by the power of the cold water circulation pipe motor 254, and the operation of the cold water circulation pipe motor 254 is controlled by the control box 400.

냉수순환배관(250)에서는 냉수순환배관온도측정센서(252)를 통해 열원수의 온도가 측정되며, 이는 컨트롤박스(400)로 전달된다. 컨트롤박스(400)는 '열원온도측정센서(233)로부터 측정된 온도와 사용자가 기설정한 온도의 차이값' 및 '열원온도측정센서(233)로부터 측정된 온도와 제1열교환기(210)를 1회 통과한 후의 배관온도측정센서(252)에서 측정된 온도의 차이값'를 바탕으로 예상순환횟수를 결정하여, 열원수가 냉수순환배관(250)을 순환할 횟수를 계산한다.In the cold water circulation pipe 250, the temperature of the heat source water is measured through the cold water circulation pipe temperature measuring sensor 252, which is transmitted to the control box 400. The control box 400 includes'the difference between the temperature measured from the heat source temperature measuring sensor 233 and the temperature preset by the user' and'the temperature measured from the heat source temperature measuring sensor 233 and the first heat exchanger 210 The expected number of cycles is determined based on the difference value of the temperature measured by the pipe temperature measurement sensor 252 after passing once, and the number of times the heat source water circulates through the cold water circulation pipe 250 is calculated.

컨트롤박스(400)에 의해 계산된 횟수만큼 열원수의 순환이 이루어져 사용자가 기설정한 온도까지 열원수의 온도가 냉각되면, 열원수의 배출을 실시한다. 이를 위하여, 컨트롤박스(400)는 제2자동체크밸브(244)를 제어하여 전환된 냉수를 배출한다.When the heat source water is circulated the number of times calculated by the control box 400 and the temperature of the heat source water is cooled to a temperature preset by the user, the heat source water is discharged. To this end, the control box 400 controls the second automatic check valve 244 to discharge the converted cold water.

냉수순환배관(250) 내부의 물을 배출하기 위하여 컨트롤박스(400)는 제2자동체크밸브(244)를 통해 제1냉수배출배관(242)과 제2냉수배출배관(246) 사이를 개방함과 동시에 제1냉수배출배관(242)과 냉수순환배관(250) 사이를 폐쇄하는 상태로 전환시킨다. 이에 따라, 순환 중이던 물이 배출되어 양어장 등의 시설에 물을 공급할 수 있다. 냉수의 배출이 완료되면 제2자동체크밸브(244)는 제1냉수배출배관(242)과 냉수순환배관(250) 사이를 개방함과 동시에 제1냉수배출배관(242)과 제2냉수배출배관(246) 사이를 폐쇄하는 최초의 상태로 대기한다.In order to discharge the water inside the cold water circulation pipe 250, the control box 400 opens between the first cold water discharge pipe 242 and the second cold water discharge pipe 246 through the second automatic check valve 244 At the same time, the first cold water discharge pipe 242 and the cold water circulation pipe 250 are switched to a closed state. Accordingly, water in circulation can be discharged to supply water to facilities such as fish farms. When the discharge of cold water is completed, the second automatic check valve 244 opens the first cold water discharge pipe 242 and the cold water circulation pipe 250 and at the same time, the first cold water discharge pipe 242 and the second cold water discharge pipe (246) Wait in the first state to close the gap.

그 다음, 다시 최초 과정으로 돌아가 열원모터(220)로부터 유입수를 받아들이게 되며, 본 발명에 따른 순환배관을 이용한 냉온수 공급 시스템은 상기한 과정을 반복하면서 양어장 등 각종 시설에 필요한 적정 온도의 냉수를 공급하게 된다.Then, it goes back to the initial process and receives the influent water from the heat source motor 220, and the cold and hot water supply system using the circulation pipe according to the present invention repeats the above-described process to supply cold water of an appropriate temperature required for various facilities such as fish farms. do.

또한, 냉수통(256)의 냉수를 냉수통모터(262)를 이용하여 팬코일유닛(260)으로 보내어 냉방에 이용하고 이를 제1자동체크밸브(234)로 보내어 순환하므로 냉수를 다목적으로 활용할 수 있다.In addition, the cold water from the cold water tank 256 is sent to the fan coil unit 260 using the cold water tank motor 262 to be used for cooling, and it is sent to the first automatic check valve 234 to circulate, so that the cold water can be used for multiple purposes. have.

한편, 본 발명에 따른 순환배관을 이용한 냉온수 공급 시스템은 제2열교환기(310)를 통해 생성된 온수를 온수통(320)에 저장하고, 상기 온수통(320)에는 온수이용장치(350)로 연결되는 온수이용장치배관(340, 360) 및 온수통모터(330)를 설치하되, 상기 온수통(320)에 저장된 온수가 과열되면 온수통모터(330)를 가동하여 저장된 온수를 온수냉각장치(370)로 이동시켜 냉각시킴으로써 온수통(320) 내부가 과열되는 것을 방지할 수 있다.On the other hand, the hot and cold water supply system using the circulation pipe according to the present invention stores the hot water generated through the second heat exchanger 310 in the hot water tank 320, and the hot water use device 350 in the hot water tank 320 Install the connected hot water use device piping (340, 360) and the hot water tank motor 330, but when the hot water stored in the hot water tank 320 is overheated, the hot water tank motor 330 is operated to cool the stored hot water ( By moving to 370 and cooling it, the inside of the hot water tank 320 may be prevented from overheating.

즉, 이를 좀 더 자세히 설명하면, 본 발명의 실시예에 따른 순환배관을 이용한 냉온수 공급 시스템은 상기 제2열교환기(310)에 연결되고, 제2열교환기(310)를 통해 가열된 온수가 저장되는 온수통(320)과, 상기 온수통(320)에 내부에 설치되며, 온수통(320)에 저장된 온수의 온도를 측정하는 온수온도측정센서(322), 상기 온수통(320)의 일측에 설치되는 온수통모터(330)와 상기 온수통모터(330)로부터 연장되는 제1온수이용장치배관(340), 상기 제1온수이용장치배관(340)에 연결되며 온수를 이용하는 온수이용장치(350), 상기 온수이용장치(350)로부터 일정온도 낮춰진 온수를 다시 온수통(320)으로 흘려보내는 제2온수이용장치배관(360)을 포함하되, 상기 온수통모터(330)는 상기 온수온도측정센서(322)로부터 측정된 온도가 사용자의 기설정한 온도보다 높아지면 컨트롤박스(400)에 의해 작동된다.That is, to explain this in more detail, the cold and hot water supply system using the circulation pipe according to the embodiment of the present invention is connected to the second heat exchanger 310, and the hot water heated through the second heat exchanger 310 is stored. A hot water temperature measuring sensor 322 which is installed inside the hot water tank 320 and measures the temperature of hot water stored in the hot water tank 320, and at one side of the hot water tank 320 The installed hot water tank motor 330, the first hot water usage device pipe 340 extending from the hot water tank motor 330, the hot water usage device 350 connected to the first hot water usage device piping 340 and using hot water. ), and a second hot water use device pipe 360 for flowing hot water lowered to a predetermined temperature from the hot water use device 350 back to the hot water container 320, wherein the hot water container motor 330 measures the temperature of the hot water. When the temperature measured by the sensor 322 is higher than the user's preset temperature, it is operated by the control box 400.

상기 온수통(320)은 제2열교환기(310)에 바로 연결된다. 즉, 상기 제2열교환기(310)는 온수통(320)을 바로 가열하는 방식이 적절할 것이다.The hot water tank 320 is directly connected to the second heat exchanger 310. That is, the second heat exchanger 310 may be suitable for a method of directly heating the hot water tank 320.

상기 온수통(320)에는 온수온도측정센서(322)가 설치된다. 상기 온수온도측정센서(322)는 온수통(320) 내부에 저장된 온수의 온도를 측정하며, 온수통(320)에 저장되는 온수의 수위를 고려하여 비교적 온수통(320)의 하단에 위치하도록 설치되는 것이 바람직할 것이다.A hot water temperature measuring sensor 322 is installed in the hot water tank 320. The hot water temperature measuring sensor 322 measures the temperature of hot water stored in the hot water tank 320, and is installed to be located at the lower end of the hot water tank 320 in consideration of the level of the hot water stored in the hot water tank 320. It would be desirable to be.

한편, 상기 온수통(320) 내부는 제1열교환기(210)를 통해 흡수되는 열에너지에 의해 냉매순환계(100) 내부의 총 에너지가 높아지고, 이에 따라 온수통(320) 내부가 과열되는 문제가 발생할 수 있다. 종래의 냉온수 공급 시스템에서는 온수통 내부가 과열될 경우 온수를 그대로 흘려보내고 새로운 물을 받아들여 이를 해결하였으나, 이 경우 사용자가 원하는 온도가 아님에도 온수가 배출되게 되어 에너지를 낭비하는 문제점이 있었다.On the other hand, the inside of the hot water tank 320 increases the total energy inside the refrigerant circulation system 100 by the heat energy absorbed through the first heat exchanger 210, thereby causing a problem that the inside of the hot water tank 320 is overheated. I can. In the conventional cold and hot water supply system, when the inside of the hot water tank is overheated, hot water is passed as it is and new water is received. However, in this case, the hot water is discharged even though the temperature is not desired by the user, thereby wasting energy.

이에 본 발명은, 상기 온수통(320) 내부가 과열되는 것을 방지하게 위한 구성으로, 온수냉각장치(370)를 이용한다.Accordingly, the present invention is configured to prevent the inside of the hot water tank 320 from being overheated, and uses a hot water cooling device 370.

상기 온수이용장치(350)는 온돌바닥의 하부로 들어가 온수를 이용하고 냉각시킬 수 있으며, 이를 통해, 방바닥을 데우면서 사용자가 겨울을 따듯하게 보내기 위한 열에너지로 이용할 수 있다. 또한, 여름철에는 온돌장치가 필요하지 않기 때문에 지하 깊숙한 곳으로 배관을 연결시켜 열을 배출시킬 수도 있으며, 배관이 계곡이나 시냇물 등 흐르는 물을 통과하도록 하여 열을 빠르게 식히는 방법도 이용될 수 있을 것이다.The hot water use device 350 can enter the lower part of the ondol floor to use and cool the hot water, and through this, it can be used as thermal energy for the user to warm the winter while warming the room floor. In addition, since an ondol device is not required in summer, heat may be discharged by connecting a pipe to a deep underground place, and a method of quickly cooling heat by allowing the pipe to pass through flowing water such as a valley or a stream may also be used.

상기 온수통(320) 내부의 온도가 과열될 경우, 과열된 온수를 온수냉각장치(370)로 보내기 위한 방법으로는 온수이용장치유입밸브(371)를 닫고 온수냉각장치유입밸브(372)와 온수냉각장치배출밸브(373)를 열어 온수통(320)에 과열된 온수가 온수냉각장치(370)를 통과함으로써 온수통(320)의 온도를 조절할 수 있게 된다.When the temperature inside the hot water tank 320 is overheated, as a method for sending the overheated hot water to the hot water cooling device 370, the hot water use device inlet valve 371 is closed, and the hot water cooling device inlet valve 372 and the hot water By opening the cooling device discharge valve 373, the hot water overheated in the hot water tank 320 passes through the hot water cooling device 370, so that the temperature of the hot water tank 320 can be adjusted.

또한, 온수이용장치(350)가 필요하지 않는 여름의 경우에도 온수냉각장치(370)를 통해 순환토록 한다.In addition, even in summer when the hot water use device 350 is not required, it is circulated through the hot water cooling device 370.

상기 온수통(320)의 온도가 적정선으로 되거나, 온수이용장치(350) 가동이 필요할 경우 온수이용장치배관(340, 360)으로만 온수가 흐르게 밸브를 개폐한다.When the temperature of the hot water tank 320 reaches an appropriate line, or when the hot water usage device 350 needs to be operated, the valve is opened and closed so that hot water flows only through the hot water usage device pipes 340 and 360.

상기 온수통모터(330)의 작동은 컨트롤박스(400)에 의해 제어될 수 있다. 상기 컨트롤박스(400)는 상기 온수온도측정센서(322)로부터 측정된 온도가 사용자의 기설정한 온도보다 높아지면 온수통모터(330)를 작동하여 온수이용장치(350)로 흘려보냈다가 다시 온수통(320)으로 유입시켜 온수통(320)에 저장된 온수의 온도를 일정량 낮추게 되는 것이다.The operation of the hot water tank motor 330 may be controlled by the control box 400. When the temperature measured by the hot water temperature measurement sensor 322 is higher than the user's preset temperature, the control box 400 operates the hot water container motor 330 to flow it to the hot water use device 350 and then again hot water. The temperature of the hot water stored in the hot water tank 320 by flowing into the bucket 320 is lowered by a certain amount.

온수가 과열될 경우 컨트롤박스(400)는 온수이용장치유입밸브(371)를 닫고 온수냉각장치(370)를 온수가 통과하도록 온수냉각장치유입밸브(372)와 온수냉각장치배출밸브(373)를 열어 과열을 방지한다.When hot water is overheated, the control box 400 closes the hot water use device inlet valve 371 and opens the hot water cooling device inlet valve 372 and the hot water cooling device discharge valve 373 so that the hot water passes through the hot water cooling device 370. Open to prevent overheating.

상기와 같은 구성을 통하여, 본 발명의 순환배관을 이용한 냉온수 공급 시스템에 따른 온수순환계(300)는 적정한 온도를 유지할 수 있을 것이다.Through the above configuration, the hot water circulation system 300 according to the cold and hot water supply system using the circulation pipe of the present invention will be able to maintain an appropriate temperature.
