본 발명은 건물의 냉·난시스템 장비인 팬코일유니트(FCU)와 VAV(Variable Air Volume)의 제어를 통하여 공기조화기와 열원장비의 제어가 가능한 냉·난방 부하 변동에 따른 냉·열원장비의 자동제어방법에 관한 것으로, 더욱 구체적으로 설명하면, 사람들이 거주하면서 작업하는 건축물의 내부의 냉난방 부하 변동에 따라 공기조화기 및 냉동기나 보일러와 같은 열원장비의 출력용량을 제어하여 가장 효율적으로 에너지를 사용할 수 있게 하는 냉·난방 부하 변동에 따른 냉·열원장비의 자동제어방법에 관한 것이다.
The present invention is the automatic control of the cooling and heating source equipment according to the heating and cooling load fluctuations that can control the air conditioner and the heat source equipment through the control of the fan coil unit (FCU) and VAV (Variable Air Volume) equipment of the building heating and cooling system The control method, and more specifically, the most efficient use of energy by controlling the output capacity of air conditioners and heat source equipment such as a refrigerator or a boiler according to the change in the heating and cooling loads of the buildings where people live and work. The present invention relates to an automatic control method of a cooling / heating source device according to a cooling / heating load variation.

일반적으로, 종래의 건물에 사용되는 냉난방 부하변동에 따른 냉온수기의 대수제어시스템은 열량에 의한 제어, 온도차에 의한 제어, 유량에 의한 제어로 냉온수기의 열원을 제어하고 있다.In general, the logarithmic water control system of a cold and hot water heater according to the heating and cooling load fluctuations used in a conventional building controls the heat source of the cold and hot water heater by control by heat quantity, control by temperature difference, and flow rate control.

즉, 도 1에 도시된 바와 같이, 건물의 지하에 설치된 복수개의 냉온수기(1)에 펌프(2)가 각기 설치되고 냉온수기에서 처리된 냉수(하절기)와 온수(동절기)가 냉온수기(1)가 공급헤더(3)에 모이고 상기 공급헤더(3)에서 분기되어 건물의 각 층으로 공급되어 각 층의 공조기, 팬코일유니트와 같은 열원장비에 열원을 공급하고 열원장비를 통해 환수된 유량과 차압밸브(4)를 통한 유량과 합해져서 환수헤더(8)를 거쳐 냉온수기(1)로 재공급되는 구조이다.That is, as shown in Figure 1, the pump 2 is installed in each of the plurality of cold and hot water heaters 1 installed in the basement of the building, the cold water (summer) and hot water (winter) treated in the cold and hot water supply is supplied by the cold and hot water heaters (1) Gathered in the header (3) and branched from the supply header (3) and supplied to each floor of the building to supply a heat source to a heat source equipment such as an air conditioner and a fan coil unit of each floor, and a flow rate and a differential pressure valve returned through the heat source equipment ( 4) is combined with the flow rate through the return header (8) to the cold and hot water heater (1) structure.

이러한 종래의 냉온수를 공급하는 냉온수기의 대수제어시스템은, 온도차에 의한 제어를 할 경우에는, 상기 냉온수기(1)를 통과하여 처리된 처리수가 모인 공급헤더(3)에서 유출되는 부분에 공급부온도센서(5)가 부착되어 온도를 체크하고 각 층을 돌아서 환수되는 부분에 환수부온도센서(5')에서 감지한 온도의 차이를 비교하여 각 냉온수기(1)의 가동시킬 대수를 결정하는 방식으로 수행되고 있으며, 이러한 방식은 냉동기전용콘트롤러(7)에서 공급측과 환수측의 온도차에 의하여 간접적으로 부하량을 구하여 냉온수기의 운전대수를 제어하는 방식으로, 각층의 온도를 정밀하게 제어하지 못하여 전기적으로나 효율적으로 냉온수기를 사용할 수 없는 문제점이 있었다.In the conventional logarithmic water control system for supplying cold and hot water, the control part of the cold / hot water machine supplies the temperature of the supply part temperature sensor (3) to a portion flowing out from the supply header (3) in which the treated water passing through the cold / hot water machine (1) is collected. 5) is attached and checks the temperature, and compares the difference of the temperature detected by the return part temperature sensor (5 ') to the part to be returned by turning each layer to determine the number of running of each cold and hot water heater (1) In this method, the controller for refrigeration controller (7) indirectly obtains the load by the temperature difference between the supply side and the return side to control the number of operating units of the cold / hot water machine, and does not control the temperature of each layer precisely. There was a problem that could not be used.

유량에 의한 제어는 공급측과 환수측의 유량의 변화를 비교하여 냉온수기의 가동을 제어하는 방식이나, 일반적으로 부하량의 변화와 유량의 변화가 직선적인 비례관계가 형성되지 않으므로 적당하지 않은 방식이다.The control by the flow rate is a method of controlling the operation of the cold / hot water machine by comparing the change in the flow rate on the supply side and the return side, but in general, it is not suitable because the change in load amount and the change in flow rate do not form a linear proportional relationship.

그리고, 열량에 의한 제어는 부하계통에 흐르는 유체의 공급측과 환수측의 온도의 변화와 유량의 변화를 감지하여 냉온수기의 가동 대수를 제어하는 방식이므로 유량이나 온도만에 의한 제어보다는 정밀하게 제어하는 것이 가능하나, 이 또한, 미세한 온도변화나 유량의 변화와 같은 냉온수기의 정밀한 제어는 불가능하므로 미세한 온도의 차이나 유량의 차이를 인지하지 못하게 되므로 건물의 냉난방비용이 증가하게 되어 효율적으로 에너지를 관리할 수 없게 되는 문제점이 있었다.In addition, the control based on the amount of heat is a method of controlling the operation number of the cold / hot water machine by detecting the change of the temperature and the flow rate of the supply side and the return side of the fluid flowing in the load system. Although it is possible, however, precise control of cold and hot water heaters such as minute temperature change and flow rate change is impossible, so it is impossible to recognize the difference of minute temperature or difference in flow rate, so the heating and cooling cost of the building increases, which makes it impossible to manage energy efficiently. There was a problem.

이러한 문제점을 해결하기 위하여, 대한민국 등록특허 10-1043197에는 각 부하부(6)의 온도제어까지 가능한 냉온수기대수제어시스템이 제안된 바가 있으나, 상기의 특허에서는 각 부하부(6)의 전체의 온도제어만을 할 수 있을 뿐이고, 각 부하부(6)의 중앙과 구석의 온도의 변화 등을 제어할 수 없게 되는 문제점이 있었다.
In order to solve this problem, Korean Patent No. 10-1043197 has proposed a cold and hot water logarithmic control system that can control the temperature of each load unit 6, but in the above patent, the overall temperature control of each load unit 6 There was a problem that only it could be done and it was not possible to control changes in the temperature of the center and the corner of each load part 6 and the like.

The present invention is provided with a fan coil unit (100) installed on the floor for cooling and heating the interior of each floor, and a damper (210) is provided in the air discharge portion of the supply duct installed on the ceiling to control the flow of air VAV (Variable Air Volume) 200, the temperature sensor 300 is provided inside the building to sense the temperature of the area and transmits to the terminal control unit 400, and receives the signal of the temperature sensor 300 A terminal control unit 400 for controlling the fan coil unit 100 and the VAV 300 in comparison with a preset reference temperature, and each fan coil control unit 100 and VAV from the terminal control unit 400. Main control unit 500 for controlling the amount of air required for heating and cooling according to the operation of the operation 200 and controlling the heat source equipment 700 such as the air conditioner 600 and the refrigerator 710 or the boiler 720 according to the result It characterized by consisting of).

상기 팬코일유니트(100)는 건물 내부에 설치되어 냉열원장비부터 유입되는 냉.난방용 유체를 코일형태의 관으로 통과시켜 냉각되거나, 뜨거워진 코일의 주변공기를 팬코일유니트팬(110)에 의하여 실내로 공급하는 장치로서 유체의 양을 조절하는 팬코일유니트밸브(120)와 연동되어 작동하며 단말제어유니트(400)에 의하여 실시간 제어된다. The fan coil unit 100 is installed inside the building to pass the cooling and heating fluid flowing from the cold heat source equipment through the coil-shaped tube, or cooled, or the surrounding air of the hot coil by the fan coil unit fan 110 As a device for supplying indoors, the device operates in conjunction with the fan coil unit valve 120 for controlling the amount of fluid and is controlled in real time by the terminal control unit 400.

상기 VAV(200)는 공기조화기(600)의 일부로서 천정에 설치되는 것으로서 공기조화기에서 발생한 공기가 천정의 급기덕트를 경유하여 실내로 공급하는 기능을 수행하며, 실내의 온도변화에 따라 VAV(200)로 토출되는 공기의 유량을 조절하는 댐퍼(210)를 구비하며, 상기 댐퍼(210)는 단말제어유니트(400)에 의하여 실시간 제어된다.

예를 들어 동절기에 난방시 실제온도가 목표온도보다 낮을 시에는 더 많은 공기양을 토출시켜야 하므로 댐퍼(210)의 열림각도를 크게하여 공기의 토출량을 크게하고, 반대의 경우에는 온도의 상승을 저지해야 하므로 공기의 토출량을 적게 하여야 하므로 열림 각도를 작게하거나 폐쇄시킨다.For example, when the actual temperature is lower than the target temperature during the winter heating, more air volume must be discharged, so the opening angle of the damper 210 is increased to increase the discharge amount of air, and in the opposite case, to prevent the increase in temperature. Since the discharge amount of air must be reduced, the opening angle is reduced or closed.

상기 온도센서(300)는 해당구역의 실시간 온도(Ta)를 측정하여 주제어장치부(500)로 송부하는 역할을 수행하는 것으로서 건물 내에 측정하고자 하는 구역에 설치되며, 상기 온도센서(300)는 해당구역의 냉난방장치인 팬코일유니트(100)와 VAV(200)의 동작을 제어하는 기초데이터인 온도데이터를 단말제어유니트(400)로 송신한다. The temperature sensor 300 serves to measure the real-time temperature (Ta) of the corresponding area and send it to the main control unit 500, which is installed in the area to be measured in the building, the temperature sensor 300 is The temperature data, which is the basic data for controlling the operations of the fan coil unit 100 and the VAV 200, which are the air-conditioning and heating devices of the zone, is transmitted to the terminal control unit 400.
