Description

팬코일 유니트{FAN COIL UNIT}FAN COIL UNIT [0002]

본 발명은 팬코일 유니트에 관한 것이다.The present invention relates to a fan coil unit.

팬코일 유니트는 실내에 설치되어, 중앙 기계실에 설치된 냉/온수 공급기로부터 공급받은 온수 또는 냉수를 주변 공기와 열교환시켜, 열교환된 공기를 토출하는 기기다.The fan coil unit is installed in the room and discharges heat-exchanged air by exchanging hot water or cold water supplied from a cold / hot water supply unit installed in the central machine room with ambient air.

팬코일 유니트는 설치 위치에 따라서, 천장형 팬코일 유니트, 스텐드형 팬코일 유니트, 바닥상치형 팬코일유니트로 구분된다.The fan coil unit is divided into a ceiling fan coil unit, a stand fan coil unit, and a floor mounted fan coil unit, depending on the installation position.

천장형 팬코일 유니트는, 천장에 설치되므로 접근성이 떨어져 유지 보수가 어렵다. 또한, 요새 같이 지진이 빈번이 발생할 경우, 자칫 팬코일 유니트가 떨어질 수 있어 위험하다.Since the ceiling type fan coil unit is installed on the ceiling, it is difficult to maintain the ceiling fan coil unit because of its accessibility. In addition, if earthquakes occur frequently like fortresses, the fan coil unit may fall, which is dangerous.

스탠드형 팬코일 유니트과 바닥상치형 팬코일 유니트는, 실내의 한 자리를 차지하므로, 실내 공간 활용도를 떨어뜨린다.Since the stand type fan coil unit and the floor mount type fan coil unit occupy a single place in the room, the indoor space utilization is lowered.

바닥상치형 팬코일 유니트는, 냉온기가 아래에서 위로 뿜어져 나오므로, 실내에 냉온풍이 퍼지기 어려워, 실내를 골고루 냉난방시키기 어렵다.In the floor mounted type fan coil unit, since the cold / hot air unit is blown out from below, it is difficult for cold and warm air to spread out in the room, and it is difficult to cool and heat the room evenly.

본 발명의 목적은, 종래 팬코일 유니트의 단점을 보완한 새로운 방식의 팬코일 유니트를 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a fan coil unit of a new type which overcomes the disadvantages of the conventional fan coil unit.

본 발명의 다른 목적은, 실내 온도 조절을 정밀하게 조절할 수 있는 새로운 방식의 팬코일 유니트를 제공하는 데 있다.It is another object of the present invention to provide a new type fan coil unit capable of precisely controlling the temperature of the room.

상기 목적을 달성하기 위한 팬코일 유니트는,According to an aspect of the present invention, there is provided a fan coil unit comprising:

팬코일 유니트에 있어서,In the fan coil unit,

상기 팬코일 유니트는 벽걸이 형 팬코일 유니트인 것을 특징으로 한다.And the fan coil unit is a wall-mounted fan coil unit.

여기서, 팬코일 유니트는,Here, in the fan coil unit,

실내 벽에 설치된 본체;A body installed on an indoor wall;

상기 본체의 내부에 설치된 제1열교환기와 제2열교환기;A first heat exchanger and a second heat exchanger installed inside the main body;

상기 제1열교환기 또는/및 상기 제2열교환기에 온수 또는 냉수를 선택적으로 공급하는 밸브;A valve for selectively supplying hot water or cold water to the first heat exchanger and / or the second heat exchanger;

상기 제1`열교환기 또는/ 및 상기 제2열교환기에서 열교환된 냉기 또는 온기를 실내로 토출시키는 팬;A fan for discharging cold air or warmth heat-exchanged in the first heat exchanger and / or the second heat exchanger to the room;

상기 실내의 온도와 습도를 측정하는 센서; 및A sensor for measuring temperature and humidity of the room; And

상기 센서로부터 신호를 받아, 상기 실내의 온도를 설정된 온도로 맞추기 위해 상기 밸브를 제어하는 제어부;를 포함하는 것을 특징으로 한다.And a controller for receiving the signal from the sensor and controlling the valve to adjust the temperature of the room to a predetermined temperature.

본 발명은 벽걸이형 팬코일 유니트이다. 따라서, 천장형 팬코일 유니트 보다 접근성이 좋아 유지보수가 쉽고, 지진 발생시 팬코일 유니트가 천장에서 떨어질 염려가 없다. 또한, 스탠드형 팬코일 유니트나 바닥상치형 팬코일 유니트와 달리 실내 공간 활용도가 높다. 또한, 바닥상치형 팬코일 유니트와 달리 냉온기가 위에서 아래로 떨어져실내를 골고루 냉난방시킬 수 있다.The present invention is a wall-mounted fan coil unit. Therefore, the fan coil unit is more accessible than the ceiling fan coil unit, and maintenance is easy, and there is no fear that the fan coil unit falls from the ceiling when an earthquake occurs. Unlike the stand-type fan coil unit and the floor-mounted fan coil unit, the indoor space utilization is high. Also, unlike the floor-standing type fan coil unit, the cooling / heating unit can be downwardly moved from the top to the bottom so that the room can be cooled and heated evenly.

또한, 본 발명은 2개의 열교환기를 구비한다. 2개의 열교환기 모두에 냉수를 공급하거나, 2개의 열교환기 모두에 온수를 공급하여 냉난방용량을 쉽게 늘릴 수 있다.The present invention also includes two heat exchangers. Cooling capacity can be easily increased by supplying cold water to both of the two heat exchangers or supplying hot water to both of the two heat exchangers.

또한, 난방시, 2개의 열교환기 중 열교환 용량이 큰 열교환기에 온수를 공급하고 동시에 열교환 용량이 작은 열교환기에는 냉수를 유량을 조절해 가며 공급하여, 실내온도를 정밀하게 조절할 수 있다.In addition, when heating, hot water is supplied to a heat exchanger having a large heat exchange capacity among the two heat exchangers, and at the same time, cold water is supplied to the heat exchanger having a small heat exchange capacity while adjusting the flow rate.

또한, 냉방시, 2개의 열교환기 중 열교환 용량이 큰 열교환기에 냉수를 공급하고 동시에 열교환 용량이 작은 열교환기에 온수를 유량을 조절해 가며 공급하여, 실내온도를 정밀하게 조절할 수 있다.In addition, during cooling, cold water is supplied to a heat exchanger having a large heat exchange capacity among two heat exchangers, and hot water is supplied to a heat exchanger having a small heat exchange capacity while adjusting the flow rate.

본체(10)의 후면에는 외기(外氣)가 흡입되는 제3흡입구(13)가 구비된다. 이렇게 본 발명은 외기를 도입하여 실내 환기도 시킬 수 있다.The main body 10 has a third suction port 13 through which the outside air is sucked. In this way, the present invention can introduce indoor air into indoor air.

본체(10)의 전면 아래에는 냉기 또는 온기가 토출되는 토출구(14)가 구비된다. 토출구(14)에는 바람의 방향을 조절하는 루버(V)가 설치된다.Below the front of the main body 10, there is provided a discharge port 14 through which cool air or warm air is discharged. The discharge port 14 is provided with a louver V for controlling the direction of the wind.

도 3에 도시된 바와 같이,As shown in Figure 3,

제1열교환기(110)에는 제1-1구멍(111), 제1-2구멍(112), 제1-3구멍(113), 제1-4구멍(114)이 구비된다. 제1-1구멍(111)으로 온수가 유입된다. 제1-2구멍(112)으로 온수가 유출된다. 제1-3구멍(113)으로 냉수가 유입된다. 제1-4구멍(114)으로 냉수가 유출된다.The first heat exchanger 110 is provided with a 1-1 hole 111, a 1-2 hole 112, a 1-3 hole 113, and a 1-4 hole 114. The hot water flows into the 1-1 hole 111. The hot water flows out to the 1-2 th hole 112. The cold water flows into the first to third holes 113. The cold water flows out to the first to fourth holes 114.

제2열교환기(120)에는 제2-1구멍(121), 제2-2구멍(122), 제2-3구멍(123), 제2-4구멍(124)이 구비된다. 제2-1구멍(121)으로 온수가 유입된다. 제2-2구멍(122)으로 온수가 유출된다. 제2-3구멍(123)으로 냉수가 유입된다. 제2-4구멍(124)으로 냉수가 유출된다.The second heat exchanger 120 is provided with a second-first hole 121, a second-second hole 122, a second-third hole 123, and a second-fourth hole 124.

제1열교환기(110)와 제2열교환기(120)의 열교환기 용량은 서로 다르다.The heat exchanger capacity of the first heat exchanger 110 and the second heat exchanger 120 are different from each other.

본 실시예에서는 제1열교환기(110)의 열교환 용량이 제2열교환기(120)의 열교환 용량보다 크다.In this embodiment, the heat exchange capacity of the first heat exchanger (110) is larger than that of the second heat exchanger (120).

이렇게 제1열교환기(110)와 제2열교환기(120)의 열교환 용량을 서로 다르게 만든 이유는, 열교환 용량이 큰 열교환기로 어느 정도 실내 온도를 맞추어 놓고, 열교환 용량이 작은 열교환기로 정밀하게 실내 온도를 조절하기 위함이다. 이는 본 발명만이 가진 중요한 특징이 된다.The reason why the heat exchanging capacity of the first heat exchanger 110 and the second heat exchanger 120 are made different from each other is that the room temperature is adjusted to some extent by a heat exchanger having a large heat exchanging capacity, . This is an important feature of the present invention.

팬(140)은 제1열교환기(110) 또는/ 및 상기 제2열교환기(120)에서 열교환된 냉기 또는 온기를 실내로 토출시킨다.The fan 140 discharges cool air or warm air heat-exchanged in the first heat exchanger 110 and / or the second heat exchanger 120 to the room.

센서(150)는 실내의 온도와 습도를 측정한다.The sensor 150 measures the temperature and humidity of the room.

제어부(160)는 센서(150)로부터 신호를 받아, 실내의 온도를 설정된 온도로 맞추기 위해 밸브(130)를 제어한다. 제어부(160)에 대한 자세한 설명은 후술한다.The control unit 160 receives the signal from the sensor 150 and controls the valve 130 to adjust the temperature of the room to a predetermined temperature.

본 발명은, 열교환기가 1개가 아닌 2개이고, 8개의 밸브와, 8개의 배관으로 구성된다. 따라서, 종래 팬코일 유니트보다 구성이 다소 복잡하다. 그럼에도 불구하고, 팬코일 유니트(1)이 천장이 아닌 벽에 설치된 관계로 접근성이 뛰어나, 복잡한 구성으로 인해 문제가 생기더라도 유지 보수가 쉽다.In the present invention, there are two heat exchangers instead of one, eight valves, and eight pipings. Therefore, the configuration is somewhat more complicated than the conventional fan coil unit. Nevertheless, since the fan coil unit 1 is installed on a wall rather than a ceiling, the accessibility is excellent, and maintenance is easy even if a problem arises due to a complicated configuration.

이하, 본 발명의 일 실시예에 따른 팬코일 유니트의 작동을 설명한다.Hereinafter, the operation of the fan coil unit according to one embodiment of the present invention will be described.
