Description

수막재배용 시설하우스의 냉난방시스템{a cold and heating system of greenhouse}Cooling and heating system of facility house for water film cultivation {a cold and heating system of greenhouse}

본 발명은 수막재배에 사용하는 냉난방용수를 연속적으로 재순환 사용할 수 있게 함으로서 사전에 지하수의 낭비 및 고갈을 예방하고, 냉난방용수의 열교환은 지하수 및 지중열을 이용하여 할 수 있게 한 수막재배용 시설하우스의 냉난방시스템에 관한 것이다.The present invention prevents wastewater and depletion of groundwater in advance by continuously recycling the cooling and heating water used for water film cultivation, and the heat exchange of the cooling and heating water in the water film cultivation facility house made possible by using groundwater and ground heat. It relates to a cooling and heating system.

주지된 바와 같이 시설하우스에서 채소나 과일을 비롯하여 화훼 등 각종 작물을 재배하는 경우 조기수확과 생산성증대 및 상품성극대화로 인한 소득증대를 위해 동절기에는 가온을 하절기에는 냉방을 하게 된다.As is well known, in the case of cultivating various crops such as vegetables, fruits, flowers, etc. in the facility house, warming is performed in the winter and cooling in the summer in order to increase incomes due to early harvest, productivity, and product maximization.

또, 위와 같이 시설하우스에 냉난방을 할 때는 석유류나 석탄, 연탄, 갈탄 등의 화석연료를 이용하는 경우를 비롯하여, 전기를 이용하는 경우, 그리고 지하수나 지열을 이용하는 경우 등 여러 가지 방법이 사용되고 있으며, 위 방법들 중 지하수를 이용하는 방법이 농가 부담이 적고 간편하여 많이 사용하는 실정이다.In addition, there are various methods for heating and cooling the facility house, such as using fossil fuels such as petroleum, coal, briquettes and lignite, using electricity, and using groundwater or geothermal heat. Among them, the method of using groundwater is a situation in which a lot of burdens and conveniences of farms are used.

그러나 많은 농가 들이 시추공을 뚫어 지하수를 퍼 올려 사용하다 보니 지하수가 점차 고갈되어 가고 있는데, 특히 많은 농가에서 야간에 집중적으로 지하수를 사용하여 냉 난방하는 경우가 많아 지하수 고갈로 난방이 중단되는 사태도 빈번하게 발생한다.However, as many farmhouses use groundwater through the boreholes, groundwater is gradually being depleted.In particular, many farmhouses use cold groundwater at night to concentrate on cooling the groundwater. Occurs.

따라서 근자에는 안정적으로 지하수를 사용하기 위해 농가마다 경쟁적으로 시추공을 더 깊이 천공하는 실정에 있으며, 이로 인해 펌프의 소비전력 증대가 야기되어 농가부담이 한층 더 커지고 있는 실정이다.Therefore, in recent years, in order to use groundwater stably, the farmer drills the borehole deeper competitively, which causes an increase in the power consumption of the pump, resulting in an increase in farm burden.

다시 말하면 위와 같이 지하수를 퍼 올려 냉난방을 하는 방식은 시설비용과 유지 및 관리비용이 저렴하게 들어 많은 시설하우스 농가 및 버섯재배농가에서 선호하고 있으나, 많은 농가에서 동시다발적으로 지하수를 퍼 올려 사용하다보니 지하수를 집중적으로 퍼 올려 난방을 하는 야간에는 지하수가 고갈되어 난방이 중단되는 상황이 자주 발생할 수밖에 없게 되었고 이에 따라 작물이 동해나 냉해를 입는 경우도 자주 발생하여 농가에 많은 피해가 따랐다는 것이다.In other words, the method of heating and heating the ground water as above is preferred by many facility house farmers and mushroom cultivation farmers because of the low cost of facilities and maintenance and management costs, but many farmhouses use ground water simultaneously. At night, when the groundwater is intensively spread and heated, the groundwater is depleted and the heating is often stopped. As a result, the crops are often damaged by the East Sea or the cold sea, causing much damage to the farmhouse.

따라서 본 발명은 전술한 종래의 제반 문제점을 감안하여 발명한 것으로, 특히, 냉난방용수로 지하수를 이용하는 시설하우스에 있어서, 냉난방용수를 연속적으로 재순환 사용할 수 있게 함으로서 지하수의 낭비 및 고갈을 예방하고, 상기 냉난방용수의 열교환은 지하수나 지중열(또는 지하수 및 지중열을 동시에 이용할 수도 있음)을 이용하여 안정적이면서도 원활한 열교환이 이루어지게 하며, 이에 따라 시설하우스의 안정적인 냉난방유지, 수확증대, 유지비용 절감으로 인한 농가소득증대를 극대화시킬 수 있게 하려는 데 본 발명의 목적이 있는 것이다.Therefore, the present invention has been invented in view of the above-mentioned conventional problems. In particular, in a facility house using groundwater as cooling and cooling water, it is possible to continuously recycle and use cooling and heating water to prevent waste and exhaustion of groundwater, and Water heat exchange allows stable and smooth heat exchange using groundwater or ground heat (or ground water and ground heat at the same time), thus providing farmhouses with stable heating and cooling facilities, increased harvesting, and reduced maintenance costs. It is an object of the present invention to maximize the income increase.

상기와 같은 목적 달성을 위해 본 발명은 다음과 같이 구성된다.The present invention is configured as follows to achieve the above object.

When the stored water is insufficient, the water storage tank 20 is connected to the water level control pump 24 for automatically supplying the replenishment water from the replenishment water tank 10,

상기 저수탱크(20)의 하부 내측으로 연결 구성되어 지하수 또는 지중열에 의해 냉난방용수를 열 교환시킬 수 있게 한 열교환관(30)과,A heat exchange pipe 30 configured to be connected to the lower inner side of the water storage tank 20 so as to exchange heat and cooling water by groundwater or ground heat;

지중에 깊게 지하수 시추공(60)을 천공하여 상기 열교환관(30)이 돌아 나오도록 설치하고Deeply drilled underground water borehole 60 in the ground to install the heat exchanger tube 30

상기 열교환관(30)을 통과한 냉난방용수를 시설하우스(50)로 공급하는 급수펌프(40)와,A water supply pump 40 for supplying cooling and heating water passed through the heat exchange tube 30 to the facility house 50;

상기 급수펌프(40)와 연결 구성됨과 동시에 시설하우스(50)의 워터커튼(51) 상단에 연결 설치되는 급수관(52)으로 이루어짐을 특징으로 하는 수막재배용 시설하우스의 냉난방 시스템이다.It is connected to the water supply pump 40 and at the same time the heating and cooling system of the water film cultivation facility house, characterized in that consisting of a water supply pipe 52 is connected to the top of the water curtain 51 of the facility house 50 is installed.

한편, 열교환관(30)을 주름관으로 형성하게 되면 한층 더 열교환 효과를 높일 수 있다.On the other hand, when the heat exchanger tube 30 is formed of a corrugated tube can further increase the heat exchange effect.

또 상기 급수관(52)에 일정간격으로 순간가열히터(53)를 더 장착 구성하면 혹한기 난방시 2단계에 걸쳐 가온을 시킬 수 있어 훨씬 안정적인 난방효과가 따르게 된다.In addition, when the instantaneous heating heater 53 is further installed and configured at a predetermined interval in the water supply pipe 52, heating can be performed in two stages during the cold weather heating, and thus a much more stable heating effect is followed.

상기 열교환관(30)은 전술한 바와 같이 시추공(60)을 천공하여 수직으로 설치 사용할 수 있음은 물론, 수평으로도 매립 구성하여 지중열에 의한 열교환이 이루어지도록 구성함을 특징으로 하는 수막재배용 시설하우스의 냉난방시스템이다.The heat exchange tube 30 can be installed vertically by drilling the borehole 60 as described above, as well as horizontally embedded in the water film cultivation facility characterized in that the heat exchange by geothermal heat is configured to be configured Heating and cooling system.

이와 같이 구성된 본 발명은 열교환관(30)을 시추공(60) 속에 투입시켜 열교환관을 통과하는 냉난방용수가 지하 깊은 곳의 암반 등을 흐르는 지하수 및 지중열의 작용에 의해 열교환 되게 한 것으로서, 지하수를 퍼 올려 냉난방을 하는 것이 아님으로 지하수의 낭비 및 고갈을 사전에 예방할 수 있다. 따라서 본 발명은 환경 친화적인 발명인데다가 지하수를 퍼 올리는데 필요한 펌프(통상 시추공의 깊이가 깊을수록 소비전력이 크게 증대하게 됨)등의 장비도 불필요하게 되어 시설비를 비롯한 전기료를 크게 절감할 수 있는 효과도 따른다.In the present invention configured as described above, the heat-exchanging tube 30 is inserted into the borehole 60 so that the cooling and heating water passing through the heat-exchanging tube is heat-exchanged by the action of groundwater and underground heat flowing through the rock in the deep underground. By not heating up and heating, it is possible to prevent waste and exhaustion of groundwater in advance. Therefore, the present invention is an environmentally friendly invention, and equipment such as pumps (usually, the deeper the borehole, the greater the power consumption increases), which is necessary for pumping groundwater, also becomes unnecessary, thereby greatly reducing the cost of electricity including facility costs. Also follows.

또 혹한으로 인해 지하수 및 지열만으로 원하는 적정온도의 열교환이 어려워져서 냉난방용수가 적정온도를 유지하지 못할 경우에는 냉난방용수가 순간가열히터(53)에 의해 가열되게 함으로서 냉난방용수가 항상 균일한 수온을 유지하게 하고, 이에 따라 균일하고 안정적인 난방이 이루어지는 효과도 따른다.In addition, if the cold and warm water is unable to maintain the proper temperature because only the ground water and the geothermal heat make it difficult for the cold, the cooling and heating water is heated by the instantaneous heating heater 53 so that the cooling and heating water is always maintained at a uniform water temperature. And accordingly, the effect of achieving a uniform and stable heating.

본 발명은 지하수나 지표수, 상수도 등의 용수를 시설하우스의 냉난방용수로 반복 순환시켜 사용할 수 있게 하되, 냉난방용수의 열교환은 지하수 및 지중열로 할 수 있게 함으로서 냉난방용수의 열교환이 안정적으로 이루어지게 하면서 지하수의 낭비와 고갈을 사전에 예방할 수 있게 구성한 환경 친화적인 발명인 것이다.The present invention can be used by repeatedly circulating water such as groundwater, surface water, waterworks, etc. into the cooling and heating water of the facility house, the heat exchange of the cooling and heating water can be made into the groundwater and underground heat to ensure stable heat exchange of the cooling and heating water It is an environmentally friendly invention that can be configured to prevent waste and exhaustion in advance.

본 발명의 구성은The configuration of the present invention

땅속에 매립되며 지하수나 지표수, 상수도물 등의 용수를 항상 일정수량으로 저장 유지하면서 후술하는 저수탱크(20)의 수위를 안정적으로 유지시켜주도록 작용하는 보충수탱크(10)와,A replenishment tank (10) buried in the ground and acting to maintain the water level of the reservoir tank (20) to be described later while maintaining and storing water such as groundwater, surface water, and tap water at a constant quantity;

땅 속에 매립되며 내부 소정위치에 수위조절밸브(21)가 장착되어 상기 보충수탱크(10)로 부터 물을 공급받아 항상 일정수위를 유지하고, 상측에는 시설하우스(50)를 돌아 나온 냉난방용수가 재 유입되게 하는 유입관(22)과 일정수위를 넘으면 넘쳐 배출되도록 구성된 오버드레인관(23)이 장착되며, 저장된 물이 부족할 경우 수위조절밸브(21)의 신호에 의해 상기 보충수탱크(10)로부터 보충수를 자동 공급시키도록 수위조절펌프(24)가 연결 구성된 저수탱크(20),It is buried in the ground and is equipped with a water level control valve 21 at a predetermined position therein to receive water from the replenishment water tank 10 to maintain a constant water level at all times, and the heating and cooling water exiting the facility house 50 on the upper side. The inlet pipe 22 to be re-introduced and the overdrain pipe 23 is configured to be discharged overflowed when a certain level is exceeded, and when the stored water is insufficient, the replenishment water tank 10 by the signal of the water level control valve 21 Reservoir tank 20, the level control pump 24 is configured to automatically supply replenishment water from

상기 저수탱크(20)의 하부 내측으로 연결 구성되어 지하수 또는 지중열에 의해 냉난방용수를 열 교환시킬 수 있게 한 열교환관(30)과,A heat exchange pipe 30 configured to be connected to the lower inner side of the water storage tank 20 so as to exchange heat and cooling water by groundwater or ground heat;

땅속 깊게 지하수 시추공(60)을 천공하여 상기 열교환관(30)이 삽입되어 돌아나오도록 설치하고Drilling the groundwater borehole 60 deep into the ground and installed so that the heat exchanger tube 30 is inserted and returned

상기 열교환관(30)을 통과한 냉난방용수를 시설하우스(50)로 공급하는 급수펌프(40)와,A water supply pump 40 for supplying cooling and heating water passed through the heat exchange tube 30 to the facility house 50;

상기 급수펌프(40)와 연결 구성됨과 동시에 시설하우스(50)의 워터커튼(51) 상단에 연결 설치되는 급수관(52)으로 이루어짐을 특징으로 하는 수막재배용 시설하우스의 냉난방 시스템이다.It is connected to the water supply pump 40 and at the same time the heating and cooling system of the water film cultivation facility house, characterized in that consisting of a water supply pipe 52 is connected to the top of the water curtain 51 of the facility house 50 is installed.

상기 지하수 시추공(60)의 깊이는 지역이나 지형에 따라 다소 차이가 있기는 하나 지하수를 얻기 위해 천공하는 시추공(60)의 깊이가 통상 짧게는 40?50m에서 길게는 300?400m의 깊은 상태이고, 또 지하수는 땅속에서도 암반사이로 계속 흐르는 상태이기 때문에 동절기에는 12℃내외, 하절기에는 18℃내외의 고른 수온을 얻을 수 있으며, 땅속의 지중열 또한 지하수의 수온과 비슷한 온도를 유지하게 된다.Although the depth of the groundwater borehole 60 is somewhat different depending on the region or the terrain, the depth of the borehole 60 that is drilled to obtain groundwater is usually in a deep state of 40 to 50m to 300 to 400m long. In addition, because the groundwater continues to flow between the rocks in the ground, it is possible to obtain even water temperatures of about 12 ° C in winter and 18 ° C in the summer, and the ground heat in the ground also maintains a temperature similar to that of groundwater.

따라서 본 발명은 상기와 같은 지하수와 지중열을 효율적으로 활용하기 위해 시추공(60)에 저수탱크(20) 및 급수관과 연결된 열교환관(30)을 삽입설치하고 급수펌프(40)로서 냉난방용수를 강제 순환시킴으로서 상기 시추공(60)과 더불어 이곳에 삽입된 열교환관(30)이 하나의 열교환기로서의 기능을 할 수 있게 한 것이 큰 특징인 것이다.Therefore, the present invention inserts the heat exchange pipe 30 connected to the reservoir tank 20 and the water supply pipe in the borehole 60 in order to efficiently utilize the ground water and ground heat as described above, and forced the cooling and heating water as the water supply pump 40. By circulating through the borehole 60, the heat exchanger tube 30 inserted therein is able to function as a heat exchanger.

이와 같이 구성된 본 발명은 깊이가 깊게 형성된 시추공(60)과, 상기 시추공(60)에 삽입 설치되는 열교환관(30)의 유기적인 작용에 의해 냉난방용수를 열 교환시킴에 따라 냉난방시 지하수를 퍼 올려 사용할 필요가 전혀 없어 지하수낭비 및 고갈을 초래할 염려가 없는 매우 환경 친화적인 시스템이고, 더불어 지하수와 지중열을 함께 이용하여 냉난방용수를 열 교환시킴으로서 열교환 효율을 극대화시켜주게 되어 시설하우스의 냉난방을 안정적으로 유도할 수 있게 되는 것이다.The present invention configured as described above spreads groundwater during cooling and heating as the heat and cooling air is exchanged by the organic action of the borehole 60 formed deeply and the heat exchanger tube 30 inserted into the borehole 60. It is a very environmentally friendly system that does not cause groundwater wastage and exhaustion because it does not need to be used at all. It also maximizes heat exchange efficiency by heat exchange of cooling and heating water by using groundwater and underground heat to reliably cool and heat the facility house. It will be able to induce.

다시 말하면 시추공(60)내에 삽입 설치된 열교환관(30) 내부를 급수펌프(40)에 의해 냉난방용수가 순환되면서 시추공(60) 내부의 지중열과 시추공(60) 내부의 암반을 흐르는 지하수가 동시에 작용하여 냉난방용수를 열 교환시키는 구성이기에 그 효율이 매우 안정적이면서 뛰어나다는 것이다.In other words, while cooling and cooling water is circulated in the heat exchange pipe 30 installed in the borehole 60 by the water supply pump 40, the ground heat flowing in the borehole 60 and the groundwater flowing through the rock in the borehole 60 simultaneously operate. It is a configuration that heat-exchanges cooling and heating water, so the efficiency is very stable and excellent.

그리고 열교환관(30)의 단면적을 넓히면 열 교환효율을 더 높일 수 있으므로 열교환관(30)을 주름관이나 또는 외주면에 다수의 흡열돌기를 돌출 형성하여 사용하면 한 층 더 효과적이라 하겠다.In addition, since the heat exchange efficiency can be further increased by increasing the cross-sectional area of the heat exchanger tube 30, the heat exchanger tube 30 may be further effective by forming a plurality of endothermic protrusions on the corrugated tube or the outer circumferential surface thereof.

한편, 시설하우스(50)의 워터커튼(51) 상단에 설치되는 급수관(52)에 일정간격으로 순간가열히터(53)를 더 장착하면, 혹한기에 급수펌프(40)에 의해 열교환관(30)을 통과한 냉난방용수가 급수관(52)에 공급될 때 그 수온을 측정하여 설정온도 이하의 낮은 온도일 때 자동으로 작동하여 냉난방용수를 설정온도로 순간적으로 가열 공급시킬 수 있게 하는 것이다. 따라서 혹한기시 냉난방용수를 지하수와 지중열에 의해 1차 가열하고, 지하수와 지열만으로는 부족할 경우에는 순간가열히터(53)에 의한 2차 가열이 이루어짐에 따라 난방이 매우 안정적으로 이루어질 수 있게 되는 것이다.On the other hand, when the instantaneous heating heater 53 is further mounted to the water supply pipe 52 installed on the top of the water curtain 51 of the facility house 50 at a predetermined interval, the heat exchange pipe 30 by the water supply pump 40 in the cold weather When the heating and cooling water is passed to the water supply pipe 52 is measured by the water temperature is automatically operated when the temperature is lower than the set temperature to enable the heating and cooling water to be instantaneously heated to the set temperature. Therefore, in the cold weather heating and cooling water is primarily heated by the groundwater and ground heat, and if only groundwater and geothermal heat is insufficient, the secondary heating by the instantaneous heating heater 53 is made to be very stable heating.

도 4는 열교환관(30)을 지중에 수평으로 매설한 상태를 보여주는 예시도로서, 이는 지열에 의한 열교환 효율을 높이기 위해 저수탱크(20)로부터 난방용수가 공급되는 급수부(31)와, 공급된 난방용수가 지열에 의해 원활하게 열 교환될 수 있도록 직경이 작은 다수의 관체(32)로 이루어진 가열관부(33)와, 상기 가열관부(33)를 통과한 난방용수가 모아지는 집수부(34)로 이루어진 구성으로서 난방용수가 순환되는 과정에서 신속하게 지열에 의한 열교환이 이루어질 수 있게 구성하는 것이 바람직하다.4 is an exemplary view showing a state in which the heat exchanger tube 30 is horizontally embedded in the ground, which is a water supply unit 31 to which heating water is supplied from the water storage tank 20 in order to increase the heat exchange efficiency due to the geothermal heat. The heating tube portion 33 is formed of a plurality of small diameter pipes 32 so that the heating water can be heat exchanged by the geothermal heat, and the collecting portion 34, the heating water collected through the heating tube portion 33 is collected. As a configuration, it is preferable to configure the heat exchange by geothermal heat in the process of circulating the heating water.

이하 본 발명의 작용을 설명하면 다음과 같다.Hereinafter will be described the operation of the present invention.

먼저 보충수 탱크(10)에는 지하수(지하수가 적거나 고갈된 경우는 하천물을 비롯한 지표수도 됨)를 저장한다. 상기 보충수 탱크(10)의 지하수는 저수탱크(20)로 공급되는데 저수탱크(20)의 수위가 설정수위에 못 미칠 경우에는 수위조절밸브(21)가 이를 감지하여 수위조절펌프(24)를 동작시킴으로서 보충수 탱크(10)에 저장된 물을 공급받게 되고, 설정수위가 되면 수위조절밸브(21)가 이를 감지하여 수위조절펌프(24)의 동작을 정지시킨다.First, the replenishment water tank 10 stores groundwater (if the groundwater is low or exhausted, it may be surface water including river water). The ground water of the replenishment water tank 10 is supplied to the water storage tank 20. When the water level of the water storage tank 20 does not reach the set water level, the water level control valve 21 detects this and supplies the water level control pump 24. By operating the water stored in the replenishment water tank 10 is supplied, the water level control valve 21 detects this when the set water level stops the operation of the water level control pump 24.

또, 상기 저수탱크(20)에는 열교환관(30)이 연결되어 있고, 상기 열교환관(30)은 땅속으로 깊게 천공된 시추공(60)을 통과하면서 지하수 및 지중열에 의해 열교환되도록 구성되어 있으므로 급수펌프(40)에 의해 냉난방용수가 급수관(52)으로 공급될 때 저수탱크(20)에 저장된 냉난방용수가 자연적으로 유입 순환되면서 시추공(60) 내에서 지하수와 지중열에 의해 열교환 공급되게 되는 것이다.In addition, since the heat exchange tube 30 is connected to the water storage tank 20, the heat exchange tube 30 is configured to exchange heat by groundwater and ground heat while passing through a borehole 60 deeply drilled into the ground. When the cooling and heating water is supplied to the water supply pipe 52 by the 40, the cooling and cooling water stored in the water storage tank 20 is naturally introduced and circulated so that heat is supplied by groundwater and ground heat in the borehole 60.

특히, 상기한 시추공(60) 내에는 지하수가 고여 있기 보다는 지하의 암반사이로 흐르는 상태이기 때문에 지하수의 수온이나 지중열이 항상 일정한 상태로 유지되게 되며, 따라서 냉난방용수의 열 교환이 항상 안정적으로 이루어지게 됨으로서 고른 냉난방효율을 기대할 수 있게 된다.In particular, in the borehole 60, the groundwater flows between underground rocks rather than standing, so that the water temperature and ground heat of the groundwater are always maintained in a constant state, so that the heat exchange of cooling and heating water is always stable. As a result, even heating and cooling efficiency can be expected.

또, 시추공(60) 내의 지하수와 지중열로 열 교환시키기 때문에 히트펌프와 같은 고가의 장비가 불필요하여 시설비가 적게 드는 이점도 있다.In addition, since heat is exchanged with the ground water in the borehole 60 and the ground heat, expensive equipment such as a heat pump is unnecessary, and thus there is an advantage that the facility cost is low.

또, 혹한기에 지하수 및 지중열만으로 냉난방용수의 열교환이 원활하게 이루어지지 못할 때는 2차적으로 급수관(52)에 장착된 순간가열히터(53)가 동작하여 냉난방용수를 가열시켜 공급시킴으로서 혹한기라 하더라도 안정적인 사용이 가능하기 때문에 작물이 냉해나 동해를 입는 경우를 사전에 예방할 수 있게 된다.In addition, when the heat exchange of the cooling and heating water is not performed smoothly by only the ground water and the ground heat during the cold season, the instantaneous heating heater 53 mounted on the water supply pipe 52 is operated to supply the heating and cooling water for stable cooling even in the cold weather. It can be used to prevent crops from getting cold or frozen.
