Description

온실용 냉·난방 절환 시스템 {Cooling-heating conversion system for a greenhouse} Cooling-heating conversion system for a greenhouse

본 발명은 온실의 온도 및 습도를 조절, 제어할 수 있는 열교환 방식의 냉·난방 절환 시스템에 관한 것이다.The present invention relates to a heat exchange type cooling and heating switching system capable of controlling and controlling the temperature and humidity of a greenhouse.

온실은 주로 농업 분야에서 계절에 관계없이 상품을 재배하하여 농가의 수입을 증가시키는 수단으로 이용되고 있다. 이러한 온실은 경작물이 건강하고 정상적으로 성장하기 위하여 필요로하는 환경, 중요하게는 적정한 온도와 습도, 이산화탄소 농도 등을 유지하여야 한다. 이에 온실내 작물의 적정한 생장환경을 제공하기 위하여, 각종의 장치나 시스템 기타 구조물들이 필요하게 되는 것이다.Greenhouses are mainly used in the agricultural sector as a means of increasing the income of farmers by growing goods regardless of season. These greenhouses must maintain the environment, importantly the appropriate temperature and humidity, and carbon dioxide concentration, which are necessary for the healthy and normal growth of crops. In order to provide an appropriate growth environment for crops in the greenhouse, various devices, systems and other structures are needed.

도 1을 참조하면, 종래의 온실 시스템은 온실(1) 내에 구비되는 이산화탄소센서, 온도센서, 습도센서 등과 개폐창(2), 그리고 보일러(3)에서 연장된 튜브레일 배관(4)을 포함하여 구성된다.Referring to FIG. 1, a conventional greenhouse system includes a carbon dioxide sensor, a temperature sensor, a humidity sensor, an opening / closing window 2, and a tube rail pipe 4 extending from the boiler 3 provided in the greenhouse 1. It is composed.

상기 시스템에서, 상기 온도센서 및 습도센서에 의하여 측정된 값이 기준치 이상으로 되면, 개폐창(2)이 개방되어 온실 내의 습기와 온기를 외부로 방출함으로써 온도와 습도를 낮추게 된다. 그리고 온실 내의 온도가 기준치 이하로 떨어지면 보일러(3)가 가동되어 배관(4)을 가열함으로써 실내 온도를 높이게 된다. 이 때 온실 내의 이산화탄소가 개폐창(2)을 통하여 배출되는데, 그리하여 실내 이산화탄소의 농도가 기준치 이하로 떨어지면 외부의 탱크로부터 이산화탄소가 실내로 공급된다.In the system, when the values measured by the temperature sensor and the humidity sensor are above the reference value, the opening and closing window 2 is opened to lower the temperature and humidity by releasing moisture and warmth in the greenhouse to the outside. When the temperature in the greenhouse falls below the reference value, the boiler 3 is operated to heat the pipe 4 to increase the room temperature. At this time, the carbon dioxide in the greenhouse is discharged through the opening and closing window (2), so that when the concentration of indoor carbon dioxide falls below the reference value, carbon dioxide is supplied to the room from an external tank.

이와 같이, 종래의 온실 시스템은 개폐창(2)을 개방하여 온도와 습도를 낮추는 한편, 온도가 낮아지면 보일러(3)을 가동하여 난방을 하는데, 이 때 외부온도의 영향을 많이 받아 외기가 낮을수록 실내 난방부하가 많이 발생하여 에너지의 낭비가 초래되고 있다.As described above, the conventional greenhouse system opens and closes the window 2 to lower the temperature and humidity, and when the temperature is lowered, the boiler 3 is heated to heat the air. Increasingly, the heating load is generated a lot of energy is wasted.

또한, 개폐창(2)을 이용하여 온도와 습도를 낮추고 맞추는 것은 조절의 한계가 있으며 한편, 환절기 특히 주간에는 개폐창(2)의 개방이 많아지는데 우리나라 기후 특성상 계절풍과 해충으로 인하여 작물 재배에 많은 어려움이 있다. 그리고 하절기에는 개폐창(2)이 개방되어도 온도 및 습도가 너무 높은 상태로 있으며, 열대야를 동반하는 경우 작물의 생육에 지장이 초래되고 있다.In addition, lowering and matching the temperature and humidity using the opening and closing window (2) has a limit of control, while the opening of the opening and closing window (2) increases during the transitional season, especially in the daytime. There is difficulty. And in the summer, even if the opening and closing window (2) is open and the temperature and humidity is too high, when accompanied by a tropical night has been a problem in the growth of crops.

이에 다른 방법으로, 근래에는 다른 설비나 장치를 대체하여 냉·난방 설비로써 온실의 상부에 FCU(팬코일유닛)를 설치하여 사용하는 경우가 있다. 그러나 이 경우 냉방과 난방이 쉽고 빠르게 이루어지지 않으며, 제습의 문제가 심각하게 동반된다. 또한 상기 FCU를 사용하는 경우 작물 손상의 우려가 있기 때문에 강하고 빠르게 동작할 수 없으며, 온실 내의 상·하부 온도차가 크게 되고, 오히려 작물의 상측이 난방에 직접 접촉하게 됨으로써 온실의 온도조절 및 작물의 건강한 생육에 지장을 주게 된다. As another method, in recent years, there is a case in which an FCU (fan coil unit) is installed in the upper portion of the greenhouse as a cooling / heating facility in place of other facilities or devices. In this case, however, cooling and heating are not easy and quick, and the problem of dehumidification is seriously accompanied. In addition, when the FCU is used, there is a risk of crop damage, so it cannot operate quickly and strongly, and the temperature difference between the upper and lower parts of the greenhouse becomes large. It will interfere with growth.

본 발명의 목적은 필요에 따라 냉·난방의 절환 수행이 가능하여, 외부조건에 따라 냉방과 난방 및 제습을 자동으로 수행하는 냉·난방 절환 시스템을 제공하고자 하는 것이다.

Another object of the present invention is to provide a cooling and heating switching system that can be heated at the same time in the upper and lower parts of the greenhouse easy and fast heating.

In addition, it is to provide an advantageous heating and heating switching system for the safe growth of crops in the greenhouse.

In this embodiment, the hot water tank and the cold water tank are illustrated as the warmer and the cooler, and it is noted that the heat source switching valve is designated as a water switching valve.

본 발명의 절환 시스템(10)은 온실(11)의 외부에 배치되고, 온수 및 냉수를 각각 저장하는 온수탱크(12)와 냉수탱크(13), 그리고 상기 온수탱크(12)와 냉수탱크(13)로부터 공급라인으로 연장되어 온실(11)의 하부 및 상부에 각각 배치되는 튜브레일 배관(14)과 팬코일유닛(15)을 포함한다. 상기 튜브레일 배관(14)과 팬코일유닛(15)은 잘 알려져 있는 사항이므로, 상세한 설명은 생략한다. Switching system 10 of the present invention is disposed outside the greenhouse 11, the hot water tank 12 and the cold water tank 13 for storing hot and cold water, respectively, and the hot water tank 12 and cold water tank 13 And a tube rail pipe 14 and a fan coil unit 15 extending from the supply line to the supply line and disposed at the lower and upper portions of the greenhouse 11, respectively. Since the tube rail pipe 14 and the fan coil unit 15 are well known matters, detailed description thereof will be omitted.

그리고, 상기 공급라인에는 온수탱크(12)와 냉수탱크(13) 내의 온수 및 냉수의 공급을 자동절환하는 수절환밸브(16,17,18,19)가 배치되며, 뒤이어 상기 수절환밸브(16,17,18,19)에 의해 절환되어 상기 튜브레일 배관(14) 및 팬코일유닛(15)으로 공급되는 물의 흐름을 자동절환하는 경로절환밸브(20,21,22,23)가 배치된다. In addition, water supply valves 16, 17, 18, and 19 for automatically switching the supply of hot water and cold water in the hot water tank 12 and the cold water tank 13 are disposed in the supply line, followed by the water switching valve 16. Path switching valves (20, 21, 22, 23) are switched by the switch, 17, 18, 19 to automatically switch the flow of water supplied to the tube rail pipe (14) and the fan coil unit (15).

상기한 절환밸브(16~23)는 온실(11) 내 적어도 온도조건을 포함하는 환경에 따라 해당 공급라인을 자동 개폐한다. 이에 온실(11)의 내부에는 온도센서가 구비되며, 그 외에 습도센서 및 이산화탄소 농도센서 등이 더 구비될 수 있다.The switching valves 16 to 23 automatically open and close the corresponding supply line according to an environment including at least temperature conditions in the greenhouse 11. The temperature sensor is provided inside the greenhouse 11, and in addition, a humidity sensor and a carbon dioxide concentration sensor may be further provided.

바람직하게, 본 발명의 절환 시스템(10)은, 상기 공급라인 상 수절환밸브(16,17,18,19)의 후방에 배치되는 순환펌프(24)와 수온조절기(25)를 더 포함한다. 상기 순환펌프(24)는 물의 흐름을 원활하게 하기 위하여 구비되며, 수온조절기(25)는 난방 또는 냉방을 효과적이고 빠르게 하기 위하여 구비된다.Preferably, the switching system 10 of the present invention further includes a circulation pump 24 and a water temperature regulator 25 disposed behind the water switching valves 16, 17, 18, and 19 on the supply line. The circulation pump 24 is provided to smooth the flow of water, the water temperature controller 25 is provided for effective and fast heating or cooling.

상기한 절환 시스템(10)은 센서의 감지동작과 그에 따른 제어회로의 명령에 의하여 상황별로 다양하게 동작하지만, 크게는 다음 세가지의 경우와 그에 따른 동작 양태를 갖는다.The switching system 10 operates in various ways depending on a sensing operation of a sensor and a command of a control circuit. However, the switching system 10 has three cases and an operation mode according to the following.

첫째, 난방부하가 적을 때 튜브레일 배관(14)의 단독운전First, the independent operation of the tube rail piping 14 when the heating load is low

온실(11)의 난방부하는 외부온도에 따라 커지기도 하고 작아지기도 한다. 도 3을 참조하면, 난방부하가 작아 온실(11) 하부에 배치된 튜브레일 배관(14)에만 온수를 순환시켜도 충분한 경우에는: 수절환밸브 중 부호 16 및 18을 개방하고; 순환펌프(24)를 가동하여 온수탱크(12) 내의 온수를 공급라인으로 흐르게 하고; 경로절환밸브 중 부호 20 및 22를 개방하여 튜브레일 배관(14)에 온수를 순환시킨다. The heating load of the greenhouse 11 may increase or decrease depending on the external temperature. Referring to FIG. 3, when the heating load is small and sufficient to circulate hot water only in the tube rail pipe 14 disposed below the greenhouse 11, reference numerals 16 and 18 in the water switching valve are opened; Operating the circulation pump 24 to flow hot water in the hot water tank 12 to the supply line; The hot water is circulated through the tube rail pipe 14 by opening the symbols 20 and 22 among the path switching valves.

온실(11) 내부의 난방부하에 따라 순환펌프(24)를 온/오프하며, 수온조절기(25)에서는 최적으로 결정된 온수온도에 이르게 한다. 상기 수온조절기(25)는 도시된 바와 같은 삼방밸브를 갖는다.The circulation pump 24 is turned on / off according to the heating load inside the greenhouse 11, and the water temperature controller 25 leads to an optimally determined hot water temperature. The water temperature regulator 25 has a three-way valve as shown.

둘째, second, 동절기Winter season 튜부레일Tubule Rail 배관(14)과  With pipe (14) 팬코일유닛Fan coil unit (15) 동시운전(15) Simultaneous operation

도 4를 참조하면, 동절기에 외부온도가 낮아 튜브레일 배관(14)만으로는 일정온도의 유지가 잘 안될 경우에는: 수절환밸브 중 부호 16 및 18을 개방한 상태에서; 경로절환밸브 중 부호 21 및 22를 폐쇄하고 부호 20 및 23을 개방하여; 튜브레일 배관(14)에서 1차 열교환된 온수를 팬코일유닛(15)으로 공급함으로써; 온실(11)의 상부에서 침입하는 냉열을 차단하고 내부 온도를 일정하게 유지할 수 있도록 팬코일유닛(15)이 온/오프를 반복하면서 난방운전이 지속적으로 수행된다.Referring to FIG. 4, when the outside temperature is low in winter and the tube rail pipe 14 alone is not able to maintain a constant temperature: in the state of opening the symbols 16 and 18 of the water switching valve; Closing symbols 21 and 22 and opening symbols 20 and 23 in the path switching valve; By supplying hot water heat-exchanged primary in the tube rail pipe 14 to the fan coil unit 15; The heating operation is continuously performed while the fan coil unit 15 repeatedly turns on / off to block the cooling heat invading from the upper portion of the greenhouse 11 and maintain the internal temperature constant.

다음은 크기가 가로 100m, 세로 100m, 높이 4m인 온실(11)의 난방방식에 따라 적정한 온수온도와 피크부하를 나타낸 표이다.The following is a table showing the appropriate hot water temperature and peak load according to the heating method of the greenhouse 11 having a size of 100m in width, 100m in height and 4m in height.

위 표에서와 같이, 본 발명에 따르면 동절기 또는 혹한기에 상기 복합난방이 가능하여 낮은 온도로 난방을 하므로 열손실 내지 에너지 손실을 가능한 줄일 수 있으며, 온실의 상부 및 하부에서 동시에 난방을 하므로 신속한 난방이 가능함과 동시에 손실 내 상·하부 온도차가 거의 없도록 유지함으로써, 작물의 건강한 성장을 위하여 필요한 조건을 균일하게 유지하고 제어할 수 있다.As shown in the above table, according to the present invention, the combined heating is possible in the winter or in the cold season, so that the heating is performed at a low temperature, thereby reducing the heat loss or energy loss as much as possible. It is possible to maintain and control the conditions necessary for the healthy growth of the crops by keeping the upper and lower temperature differences in the loss as little as possible.

셋째, 주간 냉방·Third, weekly cooling 제습운전Dehumidification 및  And 하절기Summer season 야간 저온운전 Night cold operation

도 5를 참조하면, 온실(11) 내부의 온도와 습도가 기준치보다 높을 경우: 수절환밸브 중 부호 16 및 18을 폐쇄, 17 및 19를 개방하고; 순환펌프(24)를 가동하여 냉수탱크(13) 내의 냉수를 공급라인으로 흐르게 하고; 이 때 튜브레일 배관(14)으로 냉수가 공급되면 응축수가 발생되므로, 경로절환밸브 중 부호 20을 폐쇄하고 21 및 23을 개방하여 팬코일유닛(15)에 냉수를 순환시킨다. 상기 팬코일유닛(15)은 온/오프를 반복하면서 온실(11) 내부를 적정의 온도와 습도로 유지하면서 냉방운전을 수행한다.Referring to Fig. 5, when the temperature and humidity inside the greenhouse 11 are higher than the reference values: 16 and 18 of the water switching valves are closed and 17 and 19 are opened; Operating the circulation pump 24 to flow the cold water in the cold water tank 13 to the supply line; At this time, when the cold water is supplied to the tube rail pipe 14, condensed water is generated, thereby closing the reference numeral 20 of the path switching valve and opening 21 and 23 to circulate the cold water in the fan coil unit 15. The fan coil unit 15 performs the cooling operation while maintaining the inside of the greenhouse 11 at an appropriate temperature and humidity while repeating the on / off.

이 때, 온실(11) 내부의 냉방부하에 따라 순환펌프(24)를 온/오프하며, 수온조절기(25)에서는 최적으로 결정된 냉수온도에 이르게 한다. 한편, 이와 같은 냉방운전에 따른 온·습도조절에서 온실(11) 천장의 개방창(26)은 열리지 않는다. 따라서 작물의 성장에 필요한 이산화탄소가 대기중으로 방출되는 것을 방지하므로, 이산화탄소 사용의 절감 및 대기오염 방지에 도움이 된다.At this time, the circulation pump 24 is turned on / off according to the cooling load inside the greenhouse 11, and the water temperature controller 25 reaches the optimally determined cold water temperature. On the other hand, the opening window 26 of the ceiling of the greenhouse 11 in the temperature and humidity control according to the cooling operation is not opened. Therefore, the carbon dioxide necessary for growing the crop is prevented from being released into the air, thereby reducing the use of carbon dioxide and preventing air pollution.
