본 발명은 목욕탕용 열교환 장치에 관한 것으로, 보다 상세하게는 목욕탕의 폐수에 잔존한 열과, 목욕탕의 용수로 사용하고자 펌핑된 지하수의 열과, 냉탕용 냉수의 열을 히트펌프의 냉매의 증발열원으로 동시에 활용할 수 있도록 하는 열교환 장치에 관한 것이다.The present invention relates to a heat exchanger for a bath, and more particularly, the heat remaining in waste water of a bath, the ground water pumped for use as a bath water, and the cold water for cold water are simultaneously utilized as an evaporation heat source of a refrigerant of a heat pump. It relates to a heat exchange device that allows.

목욕탕에 사용되는 용수는 지하수를 펌핑하여 옥상수조에 채우고, 이를 화석에너지 또는 전기에너지로 약 50℃로 가열하여 온수탱크에 저장한 후 배관을 통해 온탕이나 샤워기로 송급되고, 냉수와 혼합하여 적절한 온도로 맞추어 사용하게 된다.The water used in the bathroom is filled with a rooftop water tank by pumping ground water, heated to about 50 ℃ with fossil energy or electric energy, stored in a hot water tank, and supplied to a hot water or shower through a pipe, mixed with cold water, and mixed with an appropriate temperature. It is used according to.

공중 목욕탕은 많은 용수가 필요하고, 계절을 불문하고 항상 뜨거운 물이 사용된 후 고온의 폐수가 그대로 방출되어 폐기된다. 이와 같이 버려지는 목욕탕 폐수는 30℃ 이상이기 때문에 그대로 배출하게 되면 에너지 낭비가 된다. 따라서 폐수로부터 열을 회수하여 이용하는 폐열회수장치가 필요하고, 통상 폐열회수장치로는 폐열회수기와 히트펌프가 사용된다.Public baths require a lot of water, and regardless of the season, hot water is always used and hot wastewater is discharged and disposed of as it is. Since the waste water is discarded as above 30 ℃, it is a waste of energy if discharged as it is. Therefore, a waste heat recovery apparatus is required for recovering heat from the waste water, and a waste heat recovery apparatus and a heat pump are usually used as the waste heat recovery apparatus.

폐열회수기는 고온으로 방출되는 폐수의 열을 냉수와 교환하도록 하여, 예열된 냉수가 온수로 가열되도록 하여 열에너지를 절감하도록 하는 단순 구조를 가진다.The waste heat recovery device has a simple structure in which heat of waste water discharged at a high temperature is exchanged with cold water, so that the preheated cold water is heated with hot water, thereby saving thermal energy.

그리고 히트펌프는 증발기와, 압축기와, 응축기와, 팽창밸브가 냉매관로에 순차적으로 연결되어 구성된다. 압축기로부터 응축기로 유입된 고온고압의 냉매가스를 사용하여 온수를 가열시키고, 이에 의해 가열된 온수를 온수탱크로 유입시킴과 동시에 응축기로부터 팽창밸브를 거쳐 증발기로 유입된 냉매가스를 목욕탕으로부터 버려지는 폐수의 열로서 증발시켜 다시 압축기로 공급되는 구조이다.The heat pump is configured such that an evaporator, a compressor, a condenser, and an expansion valve are sequentially connected to the refrigerant pipe. The hot water is heated using the high-temperature, high-pressure refrigerant gas introduced from the compressor to the condenser, thereby introducing the heated hot water into the hot water tank, and at the same time, the waste water that is discharged from the bath through the expansion valve from the condenser to the evaporator from the bath. It is a structure that is evaporated as heat and fed back to the compressor.

상기와 같은 히트펌프의 증발기에서 냉매의 증발에 필요한 열원은 폐수의 잔열을 이용하게 되어 에너지를 절감하게 되는데, 단지 폐수만의 잔열을 히트펌프의 증발열원으로 사용함으로써, 목욕탕의 초기 작동시에는 잔열을 가진 폐수의 방출이 없기 때문에 화석에너지 또는 전기에너지로써 그 상당한 열원을 제공하여야 하는 문제점이 있었다.The heat source required for evaporation of the refrigerant in the evaporator of the heat pump uses the residual heat of the waste water to save energy. By using only the residual heat of the waste water as the evaporation heat source of the heat pump, the residual heat during the initial operation of the bathroom. Since there is no discharge of wastewater with a fossil energy, there is a problem to provide a significant heat source as fossil energy or electric energy.

본 발명의 목적은 목욕탕에서의 폐수의 잔열을 보다 효과적으로 활용하여 에너지 절감을 극대화 시키고, 특히 매일매일의 초기 목욕탕 물을 데울 때 즉 고온의 폐수 방출이 없는 초기 작동시에도 히트펌프의 효율을 높이도록 지하수와 냉탕의 냉수로부터 증발기의 냉매 증발열원을 다중으로 얻을 수 있도록 하는 목욕탕용 열교환 장치를 제공함에 있다.An object of the present invention to maximize the energy savings by utilizing the residual heat of the waste water in the bath more effectively, especially to heat the initial bath water every day, that is, to increase the efficiency of the heat pump even during the initial operation without hot waste water discharge It is an object of the present invention to provide a heat exchange apparatus for a bathhouse to obtain multiple refrigerant evaporation heat sources of an evaporator from cold water of ground water and cold bath.

이하 본 발명의 구성 및 작용을 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 목욕탕용 열교환 장치는 폐수유입관(1)과 폐수유출관(2)이 설치된 탱크본체(3); 상기 탱크본체(3)의 내부에 지그재그로 설치된 냉매관(4); 상기 탱크본체(3)의 내부에 상기 냉매관(4)과 인접되게 지그재그로 설치된 지하수관(5); 상기 탱크본체(3)의 내부에 지그재그로 설치된 냉탕관(6);을 포함하여 구성된다.The heat exchange apparatus for a bath of the present invention includes a tank main body (3) provided with a wastewater inlet pipe (1) and a wastewater outlet pipe (2); Refrigerant pipe (4) is installed in a zigzag inside the tank body (3); An underground water pipe (5) zigzag installed adjacent to the refrigerant pipe (4) inside the tank body (3); It is configured to include; cold water pipe (6) installed in a zigzag in the tank body (3).

그리고 상기의 폐수유입관(1)에 밸브(7a)가 설치되고, 관로상에 펌프(10)가 설치된 순환관(12)의 양단부가 상기 탱크본체(3)의 내부와 연통되게 탱크본체(3)의 외측에 설치되며, 상기 탱크본체(3)의 내부에 펌프(10)와 밸브(7a)를 제어하는 온도센서(9)가 설치될 수도 있다. 물론 폐수유입관(1)에는 밸브(7b)가 설치된 바이패스관(11)이 설치된다.And the valve body (7a) is provided in the waste water inlet pipe (1), the tank body (3) so that both ends of the circulation pipe 12, the pump 10 is installed on the pipeline in communication with the interior of the tank body (3) ) Is installed outside, the temperature sensor 9 for controlling the pump 10 and the valve (7a) may be installed in the tank body (3). Of course, the waste water inlet pipe 1 is provided with a bypass pipe 11 provided with a valve 7b.

또한 탱크본체(3)의 내부에 다수개의 우회로격벽(8)이 설치될 수도 있다.In addition, a plurality of bypass bulkheads 8 may be installed in the tank body 3.

상기와 같은 구조의 열교환 장치에 의하여, 폐수와 지하수와 냉탕의 열이 동시에 히트펌프의 냉매 증발열원으로 작용하게 되는 특징을 가지게 된다. 즉, 목욕탕의 폐수의 열원만을 히트펌프의 증발기 열원으로 이용하던 종래의 문제점을 해소하게 되고, 이는 지하수의 항온의 특성과, 냉탕의 냉수의 온도까지 이용함에 특징이 있다.By the heat exchanger having the structure as described above, the heat of the waste water, the ground water and the cold water simultaneously has the characteristic of acting as the refrigerant evaporation heat source of the heat pump. That is, the conventional problem of using only the heat source of the wastewater of the bath as the evaporator heat source of the heat pump is solved, which is characterized by using the constant temperature of the groundwater and the temperature of the cold water of the cold water.

목욕탕 폐수의 열을 재이용하는 방법으로써 히트펌프가 활용되는데, 히트펌프의 구성부인 증발기에서의 냉매의 증발열원을 폐수가 아니더라도 지하수와 냉탕의 물로부터도 얻을 수 있게 되고, 특히 고온의 폐수가 발생하지 않는 초기에 더욱더 그 활용도가 커지게 된다.The heat pump is utilized as a method of reusing the heat of the bath wastewater, and the evaporative heat source of the refrigerant in the evaporator, which is a component of the heat pump, can be obtained from the groundwater and the cold water even if the wastewater is not wastewater. In the early stages of use, the utilization becomes more and more.

우선 본 발명은 항상 18℃ 정도의 온도를 가지면서 용출되는 지하수가 바로 옥상탱크로 유입되지 않고, 히트펌프의 증발기측에 냉매의 증발열원으로 작용한 후 옥상탱크로 유입되는 구조에 특징이 있다. 즉, 지하수가 흐르는 지하수관(5)을 탱크본체(3)의 내부에서 열교환 이루어지도록 한 후 옥상탱크로 지하수가 유입되도록 하는 구조이다.First of all, the present invention is characterized in that the groundwater eluted at a temperature of about 18 ° C. does not directly flow into the rooftop tank, but acts as an evaporative heat source of the refrigerant on the evaporator side of the heat pump and then flows into the rooftop tank. That is, the groundwater pipe 5 through which the groundwater flows is heat-exchanged in the tank body 3, and then groundwater flows into the rooftop tank.

그리고 냉탕의 물을 순환시키되, 냉탕관(6)으로 탱크본체(3)의 내부에서 열교환이 일어나도록 순환시키는 구조로 되어 있다.The water of the cold water is circulated, and the cold water pipe 6 is circulated so that heat exchange occurs inside the tank body 3.

또한 냉매관(4)을 지하수관(5)과 인접하게 탱크본체(3)의 내부에 설치된 구조로 되어 있다.In addition, the refrigerant pipe 4 has a structure provided inside the tank body 3 adjacent to the groundwater pipe 5.

뿐만 아니라 기본적인 냉매의 증발열원인 폐수는 폐수유입관(1)을 통해 탱크본체(3)의 내부로 흐르고, 다수개의 우회로격벽(8)에 의하여 긴 경로로 우회하여 폐수유출관(2)을 통해 배출되면서 열교환이 이루어 진다.In addition, the wastewater, which is the heat source of evaporation of the basic refrigerant, flows into the tank body 3 through the wastewater inlet pipe 1, and is discharged through the wastewater outlet pipe 2 by bypassing a long path by the plurality of bypass partitions 8. While the heat exchange takes place.

본 발명의 특징은 폐수와 지하수 및 냉탕의 물로부터 동시에 열을 받아 냉매의 증발열원으로 사용함에 있고, 특히 폐수가 발생하지 않는 초기에는 지하수와 냉탕의 물로부터 증발열원을 획득함에 특징이 있다.The present invention is characterized in that it receives heat from wastewater, groundwater and cold water at the same time and uses it as the evaporation heat source of the refrigerant.

따라서 탱크본체(3)에 설치된 냉매관(4)은 폐수에 의해 열교환되고, 그리고 인접된 지하수관(5)에 의해 지하수와 열교환되며, 이 때 폐수는 열전달 매체로서의 작용도 하게 된다. 그리고 냉탕관(6)으로부터도 열을 교환하게 된다.Therefore, the refrigerant pipe 4 installed in the tank body 3 is heat-exchanged by the wastewater, and heat-exchanged with the groundwater by the adjacent groundwater pipe 5, at which time the wastewater also acts as a heat transfer medium. And heat is also exchanged from the cold water pipe 6.

이 경우, 충분한 열교환이 이루어지면 폐수의 흐름이 탱크본체(3)를 통해 계속 흐르게 되나, 충분한 열교환이 이루어지지 않아 폐수의 유입온도에 비하여 적정한 크기로 떨어지지 않은 경우는 폐수가 탱크본체(3)의 내부에 머무르게 하여 충분한 열교환이 이루어지도록 하는 구조이다.In this case, if sufficient heat exchange is made, the flow of waste water continues to flow through the tank body 3, but if sufficient heat exchange is not performed and the waste water does not drop to an appropriate size compared to the inflow temperature of the waste water, the waste water of the tank body 3 It stays inside to allow sufficient heat exchange.

즉, 온도센서(9)가 폐수의 온도를 측정하여, 미리 입력된 적정치의 폐수온도로 낮아지지 않고 있을 경우, 밸브(7a)를 닫고, 펌프(10)를 작동시켜 탱크본체(3)의 내부에 있는 폐수만을 순환시키게 작동된다. 물론 밸브(7b)는 열려 폐수는 바이패스관(11)으로 배출된다.That is, when the temperature sensor 9 measures the temperature of the wastewater and does not decrease to the wastewater temperature of a predetermined value input in advance, the valve 7a is closed and the pump 10 is operated to operate the tank body 3. It operates to circulate only the wastewater inside. Of course, the valve 7b is opened and the wastewater is discharged to the bypass pipe 11.

적절한 온도로 떨어진 경우는 다시 펌프(10)의 작동을 멈추고, 밸브(7a)를 열고, 밸브(7b)를 닫아서 폐수가 탱크본체(3)를 통해 흐르게 된다.When the temperature falls to an appropriate temperature, the pump 10 is stopped again, the valve 7a is opened, the valve 7b is closed, and the waste water flows through the tank body 3.

이와 같이 본 발명은 냉매의 증발열원을 폐수에 의하지 않고서도 항온성의 지하수와 냉탕의 냉수로부터 확보할 수 있게 되어, 온수의 생성 초기에도 충분한 증발열원을 확보할 수 있어 에너지 절감이 가능하게 되고, 에너지 효율이 증대되는 효과가 있다.As described above, the present invention can secure the evaporative heat source of the refrigerant from the constant temperature groundwater and the cold water of the cold water without using the wastewater, and ensure sufficient evaporation heat source even at the beginning of the generation of hot water, thereby saving energy. The efficiency is increased.
