도 4는 본 발명의 냉난방시스템의 난방가동시 작동상태도.Figure 4 is an operating state when the heating operation of the heating and cooling system of the present invention.

본 발명은 냉난방시스템에 관한 것으로, 더욱 상세하게는 냉온수를 이용하여 건물의 냉난방을 공급하는 전수(全水)방식의 냉난방시스템에 관한 것이다.The present invention relates to a cooling and heating system, and more particularly, to an all-cooling heating and cooling system for supplying heating and cooling of a building using cold and hot water.

전수방식의 냉난방시스템이라 함은 냉난방에 필요한 열원을 물을 통해 공급하는 방식으로 주택의 바닥난방이 한 예이다. 이 방식은 난방의 경우 온수를 실내로 보내어 이를 방열기나 바닥코일, 천정 및 벽체 코일, 팬코일유니트 등에서 순환시켜 실내에 필요한 난방열을 공급하고, 냉방의 경우에는 냉수를 실내로 보내어 이를 방열기나 바닥코일, 천정 및 벽체 코일, 팬코일유니트 등에서 실내에 필요한 냉 방열을 공급한다.The electric heating and heating system is an example of floor heating of a house by supplying heat sources for air conditioning and heating through water. In this case, the heating system sends hot water to the room and circulates it in the radiator or floor coil, ceiling and wall coils, fan coil unit, etc. to supply the heating heat required for the room.In the case of cooling, it sends the cold water to the room to radiate the radiator or floor coil. In the room, ceiling and wall coils, fan coil units, etc., supply the necessary heat radiation.

이와 같이 전수방식은 냉난방시스템물의 비열이 크기 때문에 작은 유량으로 많은 열을 공급할 수 있어 열공급을 위한 에너지가 절약되며 방열기나 바닥코일, 천정 및 벽체 코일 등의 냉난방설비는 복사열 방식의 일종이므로 온도분포가 균일하여 인체에 쾌적한 장점이 있다. 따라서 전수방식의 복사냉난방설비의 적용이 크게 증가하고 있다. 하지만 이 방식을 냉방에 적용하는 경우 우리나라와 같이 고온다습한 지역에서 사용하면 냉수가 순환하는 코일부에 습기로 인해 결로가 발생하는 문제가 있다.As the specific heating method of the heating and cooling system is large, it can supply a lot of heat with a small flow rate, which saves energy for heat supply. The air-conditioning equipment such as radiators, floor coils, ceilings, and wall coils is a type of radiant heat method. It is uniform and has a pleasant advantage to the human body. Therefore, the application of the radiant heating and cooling system of the electric transmission method is increasing greatly. However, when this method is applied to cooling, when used in a high temperature and high humidity region, such as Korea, there is a problem that condensation occurs due to moisture in the coil portion where cold water circulates.

이로 인해 국내에서는 전수방식의 복사냉난방설비가 적용되지 못하고 있으며 이를 해결하기 위해 여러 가지 해결책이 제시되고 있다. 가장 일반적인 적용방식은 습기를 제거하는 방식으로 실내 공기 중의 습기를 제거하기 위해 다양한 형태의 제습기를 설치하는 것이다. 그러나 이 방식은 공기를 순환시키면서 제습기를 가동시켜야 하므로 시스템이 복잡해지고 실내의 습도를 지속적으로 측정하여 제어해야 하는 어려움이 있다.For this reason, domestic radiant heating and cooling facilities are not applied, and various solutions have been proposed to solve this problem. The most common application is to remove moisture, and to install various types of dehumidifiers to remove moisture from the indoor air. However, this method has to operate the dehumidifier while circulating the air, which complicates the system and makes it difficult to continuously measure and control the humidity in the room.

다른 방법으로 복사냉난방설비를 통과하는 냉수의 온도를 습도에 따라 노점온도이상으로 조절하여 결로를 방지하는 방법으로 이 방법 또한 정밀한 습도측정과 냉수온도제어가 필요하여 실제 적용에 어려움이 있다. 따라서 전수방식의 복사냉난방기술은 국내에서 적용되지 못하고 덕트를 이용한 전공기방식이나 덕트와 팬코일유니트를 조합한 방식이 주로 사용되고 있다. 하지만 전수방식의 복사냉난방기술은 설치비가 저렴하고 에너지가 절약되며 쾌적성이 높은 장점이 있으므로 복잡한 설비 나 제어시스템 없이도 단순한 시스템으로 냉방시의 제습문제를 해결할 수 있는 기술의 개발이 요구되고 있다.Alternatively, the method of preventing condensation by adjusting the temperature of the cold water passing through the radiant heating and heating equipment above the dew point temperature according to the humidity. This method also requires precise humidity measurement and cold water temperature control, which makes it difficult to apply in practice. Therefore, the radiative heating and heating technology of the electric transmission method is not applied in Korea, but the electric method using the duct or the combination of the duct and the fan coil unit is mainly used. However, because of the advantages of low cost of installation, energy saving, and high comfort, electric radiative heating and cooling technology is required to develop technology that can solve the dehumidification problem of cooling by simple system without complicated equipment or control system.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 냉방시 제습을 주목적으로 하는 방열기 혹은 팬코일유니트와 복사냉방을 위해 사용되는 복사판넬 혹은 복사코일을 직렬로 연결하는 냉난방설비를 구성하여 제습용의 방열기 혹은 팬코일유니트의 냉수온도가 항상 복사판넬 혹은 복사코일의 냉수온도보다 낮게 유지되도록 함으로써 복잡한 시스템구성과 제어시스템 없이도 결로의 문제가 발생하지 않는 복사냉방이 가능한 전수방식의 복사냉난방시스템을 제공하는데 있다.The present invention has been made to solve the above-mentioned problems, the object of the present invention is a radiator or fan coil unit mainly intended for dehumidification during cooling and radiation panel or radiation coil used for radiation cooling in series. By constructing air conditioning equipment to be connected, the cold water temperature of the dehumidifying radiator or fan coil unit is always kept lower than the cold water temperature of the radiating panel or the radiating coil, so that radiant cooling without condensation problems does not occur without complicated system configuration and control system. The aim is to provide a radiant heating and cooling system of all types.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

도시된 바와 같이 본 발명에 의한 직렬연결형 전수방식 냉난방시스템의 핵심 개념은 도 1에 도시된 바와 같이 냉방시 제습작용을 하는 팬코일유니트 또는 방열기(30)와, 복사냉방을 수행하는 복사판넬 또는 복사코일(50)이 하나의 수배관 회로로 연결되어 있는 것이다.As shown in FIG. 1, the core concept of the series-connected electric / cooling heating and cooling system according to the present invention is a fan coil unit or a radiator 30 that dehumidifies during cooling, and a radiant panel or radiator that performs radiative cooling. The coil 50 is connected to one water pipe circuit.

즉, 냉동기, 히트펌프 등과 같은 냉열원기기(10)에서 생산된 냉수가 수배관(20)을 통하여 우선 제습용도인 팬코일유니트 또는 방열기(30)를 통과하고 난 후, 하나의 수배관 회로(40)로 직렬 연결되어 있는 복사냉방을 위한 복사판넬 또는 복사코일(50)로 순환한 다음, 다시 냉열원기기(10)로 환수배관(60)을 통해 연결되도록 하여 높은 습도로 인한 결로를 원천적으로 방지하도록 구성된다.That is, after the cold water produced in the cold heat source device 10 such as a refrigerator, a heat pump, etc. passes through the water pipe 20 first through the fan coil unit or the radiator 30 for dehumidification, one water pipe circuit ( 40) is circulated to the radiation panel or radiation coil 50 for radiant cooling connected in series, and then connected to the cooling heat source device 10 through the return pipe 60 to induce condensation due to high humidity. Configured to prevent.

상기 냉열원기기(10)는 하나의 예로서 지열을 열원으로 이용하여 냉난방을 행하는 히트펌프시스템이 사용될 수 있는데, 히트펌프시스템이 냉열원기기(10)로 제공될 경우 12℃의 냉수를 열원으로 얻을 수 있다고 가정하면, 냉열원기기(10)에 서 생산된 12℃의 냉수가 수배관(20)를 통해 팬코일유니트 또는 방열기(30)를 통과하면서 냉방 및 제습에 이용되면, 냉수의 온도는 3℃가 높아져 15℃에 달하게 된다. 이렇게 15℃가 된 냉수를 다시 회수하지 않고 직렬연결된 수배관(40)을 통해 다시 복사판넬 또는 복사코일(50)로 순환하게 된다.As one example, the cold heat source device 10 may be a heat pump system for cooling and heating using geothermal heat as a heat source. When the heat pump system is provided to the cold heat source device 10, cold water of 12 ° C. is used as the heat source. Assuming that it can be obtained, if the cold water of 12 ℃ produced by the cold heat source device 10 is used for cooling and dehumidification while passing through the fan coil unit or the radiator 30 through the water pipe 20, the temperature of the cold water is 3 ° C is increased to reach 15 ° C. The cold water which is 15 ° C. is circulated back to the radiation panel or the radiation coil 50 through the water pipe 40 connected in series without again recovering the cold water.

복사판넬 또는 복사코일(50)을 통해 냉방작용을 수행한 냉수는 다시 온도가 3℃ 높아져 18℃에 달하게 되어 최종적으로 환수배관(60)을 통해 냉열원기기(10)로 유입된다. 이때 냉난방설비를 통과하는 냉수의 온도변화는 설비종류와 규격에 따라 달라질 수 있다.The cold water that performs the cooling action through the radiation panel or the radiation coil 50 again increases the temperature to 3 ° C. and reaches 18 ° C., and finally enters the cold heat source device 10 through the return pipe 60. At this time, the temperature change of the cold water passing through the air conditioning equipment may vary depending on the type and specification of the equipment.

이러한 직렬연결식 운전을 수행하면 결로의 발생이 원천적으로 방지되는데, 이러한 것이 가능한 것은 앞에서 설명한 바와 같이, 제습작용을 하는 팬코일유니트 또는 방열기(30)의 냉수온도가 항상 복사냉방을 수행하는 복사판넬 또는 복사코일(50)의 냉수온도에 비해 낮기 때문에 공기 중의 습기가 충분히 제거되어 복사판넬 또는 복사코일에서는 결로가 생기지 않는 수준으로 낮아지기 때문이다.When the series connection operation is performed, condensation is fundamentally prevented. This is possible because, as described above, the radiant panel or the cold water temperature of the fan coil unit or the radiator 30 that performs dehumidification always performs radiative cooling. This is because the moisture in the air is sufficiently removed because it is lower than the cold water temperature of the radiation coil 50, and the radiation panel or the radiation coil is lowered to a level where no condensation occurs.

이러한 원리를 이용하여 제습을 위한 공조설비, 화학적 제습기 등과 같은 복잡한 별도설비와 습도측정, 온도조절과 같이 복잡한 제어장치 없이도 전수방식의 제습장치를 가진 복사냉난방을 실현할 수 있다. 이와 같은 개념을 이용한 본 발명의 냉난방설비는 팬코일유니트 또는 복사코일(50)의 용량을 조절하고 난방시 병렬운전이 가능하도록 하기 위해 직렬연결뿐만 아니라 도 2와 같이 추가로 수배관을 병렬연결하여 냉난방시스템을 구성할 수도 있다.Using this principle, radiant cooling and heating with a dehumidification system of all types can be realized without complicated separate devices such as air conditioning facilities for chemical dehumidification, chemical dehumidifiers, and complicated control devices such as humidity measurement and temperature control. The heating and cooling equipment of the present invention using the above concept adjusts the capacity of the fan coil unit or the radiant coil 50 and parallelly connects the water pipes as shown in FIG. 2 to enable parallel operation during heating. It is also possible to construct a cooling and heating system.

즉, 복사판넬 또는 복사코일의 용량이 크고 많은 양의 냉수를 요구하는 경 우, 냉열원기기(10)에서 냉수가 수배관(20)를 통해 제습목적으로 팬코일 유니트 또는 방열기(30)를 통과할 뿐만 아니라, 별도의 병렬 수배관(70)을 통해 복사판넬 또는 복사코일(50)로 직접 공급되도록 구성할 수도 있다.That is, when the capacity of the radiation panel or the radiation coil is large and requires a large amount of cold water, the cold water source device 10 passes through the fan coil unit or the radiator 30 for dehumidification purposes through the water pipe 20. In addition, it may be configured to be directly supplied to the copying panel or the copying coil 50 through a separate parallel water pipe (70).

따라서 복사판넬 또는 복사코일(50)은 팬코일 유니트 또는 방열기(30)를 통과하여 공급되는 수배관(40)과 냉열원기기(10)에서 직접 공급되는 수배관(70)을 통해 필요한 냉수를 공급받게 된다. 이를 통해 복사냉방을 위해 필요한 복사판넬 또는 복사코일(50)의 냉각능력을 확대할 수 있다. 이 경우에도 복사판넬 또는 복사코일(50)을 통과하는 냉수는 팬코일 유니트 또는 방열기(30)를 통과한 냉수와 냉열원기기(10)로부터 공급된 냉수가 혼합되어 있으므로 팬코일 유니트 또는 방열기(30)의 냉수보다 온도가 높게 되어 충분한 결로방지 효과를 발휘하게 된다.Therefore, the radiation panel or the radiation coil 50 supplies the necessary cold water through the water pipe 40 supplied through the fan coil unit or the radiator 30 and the water pipe 70 directly supplied from the cold heat source device 10. Will receive. Through this, it is possible to expand the cooling capacity of the radiation panel or the radiation coil 50 required for the radiation cooling. Even in this case, since the cold water passing through the copy panel or the radiation coil 50 is mixed with the cold water passed through the fan coil unit or the radiator 30 and the cold water supplied from the cold heat source device 10, the fan coil unit or the radiator 30 The temperature is higher than that of cold water, and the condensation prevention effect is exerted.

도 3은 냉방운전시의 가동형태를 나타낸 것으로 냉열원기기(10)에서 공급된 냉수가 수배관(20)를 통해 팬코일유니트 또는 방열기(30)으로 공급되고, 일부 냉수는 수배관(70)을 통해 복사판넬 또는 복사코일에 직접 공급된다. 복사판넬 또는 복사코일(50)에는 수배관(40)를 통해 팬코일유니트 또는 방열기(30)을 통과한 냉수와 수배관(70)을 통해 냉열원기기(10)로부터 직접 공급된 냉수가 혼합되어 공급되게 된다. 복사판넬 또는 복사코일을 통과한 냉수는 수배관(60)을 통해 냉열원기기(10)로 보내진다.3 is a view illustrating an operation form in a cooling operation, in which cold water supplied from a cold heat source device 10 is supplied to a fan coil unit or a radiator 30 through a water pipe 20, and some cold water is supplied to a water pipe 70. It is supplied directly to the copy panel or the copy coil through. The radiating panel or the radiating coil 50 is mixed with the cold water passed through the fan coil unit or the radiator 30 through the water pipe 40 and the cold water directly supplied from the cold heat source device 10 through the water pipe 70. Will be supplied. The cold water passing through the radiation panel or the radiation coil is sent to the cold heat source device 10 through the water pipe 60.
