Description
본 발명은 자연식 냉온풍기에 관한 것으로, 더욱 상세하게는 지하에 묻은 파이프를 경유하는 중에 자연적으로 냉각된 냉수가 실내의 방열핀이 구비된 교환관을 회류하도록 하면서 그 상부에서 팬에 의해 공기의 흐름이 발생하도록 하여 실내에 차가운 공기를 공급하거나, 상기의 교환관에 태양열에 의해 데워진 물이 공급되도록 하여 적은 비용을 사용하면서도 소음이 없고 효율적으로 사용할 수 있도록 한 자연식 냉온풍기에 관한 것이다.The present invention relates to a natural cold and hot air fan, and more particularly, the flow of air by the fan at the top while allowing the naturally cooled cold water to flow through the exchange pipe with the heat radiation fins in the room while passing through the pipe buried underground. The present invention relates to a natural cold / hot air fan that can be used to generate cool air to the room or to supply water warmed by solar heat to the exchange tube so that it can be used efficiently and without noise while using a low cost.
일반적으로 사계절의 변화가 있는 남반구나 북반구에 거주하는 대부분의 사람들은 더울 때 더위를 식혀주어야 하고 추울 때에는 추위를 없애도록 난방을 하여야 적당한 주거환경을 유지할 수 있다는 것은 이미 잘 알려진 사실이다.In general, it is well known that most people in the southern or northern hemisphere, which have four seasons of change, need to cool down when they are hot and heat them to remove them when they are cold.
그리고 더울 때에는 선풍기나 에어컨을 사용하여 차가운 공기가 실내로 공급되어 더운 외부의 열에도 불구하고 시원함을 느끼도록 하거나, 선풍기의 바람에 의해 신체의 일부나 전부의 땀을 식히도록 하고 있다.And when it is hot, using a fan or air conditioner cool air is supplied to the room to feel cool in spite of the heat from the outside, or by the wind of the fan to cool part or all of the body sweat.
한편, 겨울의 추울 때에는 난방기에 의해 데워진 용수가 실내의 저면에 설치한 배관이나 공간에 설치한 라디에이터를 경유하도록 하고 그때 이루어지는 열교환에 의해 실내의 온도가 높아지도록 하였다.On the other hand, during the cold winter, the water warmed by the heater was allowed to pass through a pipe installed on the bottom of the room or a radiator installed in the space, and the indoor temperature was increased by heat exchange.
그러나 상기와 같은 종래 더위를 식히거나 난방을 위한 방법은 모두 별도의 전기에너지나 기름과 같은 에너지를 사용하여야 하므로 운영비가 많이 소요되는 단점이 있음은 물론, 에어컨의 경우에는 냉방을 위한 냉매의 개발이라는 문제점이 있으며, 선풍기의 경우는 주위가 더울 때에 더운 열풍을 불어주게 되는 단점이 있고, 난방을 위해 물과 같은 열매를 가열시켜는 난방기기는 여름철에는 사용할 수 없고 마찬가지로 냉방기기는 겨울철에 사용할 수 없어 장기간동안 그냥 방치애야 하는 등의 문제점이 있었다.However, the conventional method for cooling or heating the heat, such as all the use of separate electrical energy or energy, such as oil, there is a disadvantage that takes a lot of operating costs, of course, in the case of air conditioner development of a refrigerant for cooling There is a problem, and in the case of a fan, there is a drawback of blowing hot hot air when the surroundings are hot, and a heating device that heats fruits such as water for heating cannot be used in summer, and likewise, a cooling device cannot be used in winter. There was a problem such as just leaving for a long time.
이에 따라 본 발명은 상기와 같은 종래 기술의 문제점을 개선하기 위한 것으로서, 지하에 묻은 파이프를 경유하는 중에 자연적으로 냉각된 냉수가 실내의 방열핀이 구비된 교환관을 회류하도록 하면서 그 상부에서 팬에 의해 공기의 흐름이 발생하도록 하여 실내에 차가운 공기를 공급하거나, 상기의 교환관에 태양열에 의해데워진 물이 공급되도록 하여 적은 비용을 사용하면서도 소음이 없고 효율적으로 사용할 수 있도록 한 자연식 냉온풍기를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention is to improve the problems of the prior art as described above, while the cold water naturally cooled while passing through the pipe buried underground to the flow of the exchange pipe with the heat radiation fin of the room by the fan at the top It is to provide a natural cold and hot air fan to make the air flow and to supply cool air to the room, or to supply the heat exchanged by solar heat to the exchange pipe so that it can be used without noise and efficiently without noise. For that purpose.

상기 냉방용 파이프의 양측끝을 지상으로 인출하여 전환이 가능한 두 삼방밸브의 제 1 연결부에 각각 연결하고,Both ends of the cooling pipes are drawn out to the ground and connected to the first connecting portions of two three-way valves which can be switched.

상기와 같이 구성된 본 발명 자연식 냉온풍기의 동작과정을 보다 상세히 설명하면 다음과 같다.Referring to the operation of the natural cold air blower of the present invention configured as described above in more detail.
땅(1)을 원통형 구덩이(2)가 생기도록 판 후 그 내부에 지지벽(3)과 함께 동관이나 수지관의 냉방용 파이프(4)를 다수 권회하면서 매설하여 지하의 온도인 4℃에 의해 열교환되어 냉각되도록 하면서 지상으로 인출하는 동시에 태양열에 의해 발열하는 집열판(7)의 하부에 접하도록 권회된 난방용 파이프(8)의 양측끝(8a)(8b)을 지상으로 인출하여 상기 냉방용 파이프(4)의 양측끝(4a)(4b)과 난방용 파이프(8)의 양측끝(8a)(8b)을 전환이 가능한 두 삼방밸브(5)(6)의 제 1 연결부 및 제 2 연결부에 각각 연결하여 임의로 전환시키도록 함으로써 하절기와 동절기에 선택적으로 사용할 수 있도록 한 것으로서,After digging the ground 1 to form a cylindrical pit 2, and burying a large number of the cooling pipes 4 of the copper pipe or the resin pipe together with the supporting wall 3 therein, it is buried by the underground temperature of 4 ° C. The air-conditioning pipes (8a) and (8b) of the heating pipes (8) wound up to be contacted with the lower part of the heat collecting plate (7), which are drawn out to the ground while being heat-exchanged and cooled by heat, are drawn to the ground. Both ends 4a and 4b of 4) and both ends 8a and 8b of the heating pipe 8 are respectively connected to the first and second connections of the two-way valves 5 and 6, which can be switched. By switching randomly so that it can be used selectively in summer and winter,
하절기의 더운 기후에서는 삼방밸브(5)(6)를 제 1 연결부로 전환하여 연결한다.In hot climates in the summer, the three-way valves 5 and 6 are switched to the first connection part.
그러므로 땅(1)의 원통형 구덩이(2)에 다수 권회되면서 매몰된 냉방용 파이프(4)가 지하의 온도인 4℃에 의해 열교환되어 냉각되도록 한다.Therefore, the cooling pipe 4 buried while being wound in the cylindrical pit 2 of the ground 1 is heat-exchanged by the underground temperature of 4 ℃ to be cooled.
상기 냉방용 파이프(4)에 의해 냉각된 물은 삼방밸브(5)의 제 1 연결부와 제 3 연결부를 거쳐 방열핀(10)이 구비된 교환관(9)의 일측으로 공급된다.Water cooled by the cooling pipe (4) is supplied to one side of the exchange pipe (9) provided with the heat dissipation fins (10) via the first and third connections of the three-way valve (5).
상기의 교환실(11)의 상단 4 개구부(12)에서는 팬(13)에 의해 강제로 이동하는 공기인 바람에 의해 차가운 냉기를 빼앗기는 열교환이 이루어져 차가워진 바람이 실내의 온도를 낮게한다.In the upper four openings 12 of the exchange chamber 11, heat exchange is performed to deprive the cold of the cold air by the air which is forcedly moved by the fan 13 so that the cold wind lowers the indoor temperature.
그리고 상기의 교환관(9)의 타측에서는 삼방밸브(6)의 제 3 연결부 및 제 1 연결부를 거쳐 냉방용 파이프(4)로 이동하여 지하의 온도인 4℃에 의해 열교환되어 다시 냉각되도록 하는 과정을 반복하도록 함으로써 실내의 냉방을 할 수 있도록 한다.And the other side of the exchange pipe (9) is a process of moving to the cooling pipe (4) through the third connection portion and the first connection portion of the three-way valve (6) to be heat-exchanged by the underground temperature of 4 ℃ again cooled Repeat this to allow room cooling.
또한 동절기의 차가운 기후에서는 삼방밸브(5)(6)를 제 2 연결부로 전환하여 연결한다.In addition, in the cold climate of the winter season, the three-way valves 5 and 6 are switched to the second connection part.
그러므로 태양열에 의해 발열하는 집열판(7)의 하부에 접하도록 권회된 난방용 파이프(8)의 내부를 흐르는 물이 덥혀진 후 일측끝(8a)을 거치고 상기 삼방밸브(5)의 제 2 연결부 및 3 연결부를 거쳐 방열핀(10)이 구비된 교환관(9)의 일측으로 공급된다.Therefore, after the water flowing inside the heating pipe 8 wound up to contact the lower portion of the heat collecting plate 7 that is generated by solar heat is heated, it passes through one end 8a and the second connection part 3 of the three-way valve 5. It is supplied to one side of the exchange pipe (9) provided with a heat dissipation fin (10) via a connection portion.
상기의 교환실(11)의 상단 4 개구부(12)에서는 팬(13)에 의해 강제로 이동하는 공기인 바람에 의해 더운 열을 빼앗기는 열교환이 이루어져 데워진 바람이 실내의 온도를 높여주도록 한다.In the upper four openings 12 of the exchange chamber 11, a heat exchange is performed to deprive hot heat by wind, which is air forced by the fan 13, so that the warmed wind raises the indoor temperature.
그리고 상기 교환관(9)의 타측에서는 삼방밸브(6)의 제 3 연결부 및 제 2 연결부를 거쳐 태양열에 의해 발열하는 집열판(7)의 하부에 접하도록 권회된 난방용 파이프(8)의 타측으로 귀환되어 다시 데워지도록 함으로써 적은 비용을 사용하면서도 소음이 없고 효율적으로 사용할 수 있도록 한 것이다.And on the other side of the exchange pipe (9) is returned to the other side of the heating pipe (8) wound in contact with the lower portion of the heat collecting plate (7) that is generated by solar heat through the third connection portion and the second connection portion of the three-way valve (6). By reheating it, it is possible to use it at a low cost and without noise.
