본 발명은 실내기 설치 위치에 따른 멀티형 에어컨의 운전 방법에 관한 것으로, 보다 상세하게는 실내기의 위치가 실외기에서 멀리 설치되는 경우 냉매유량이 감소되는 것을 방지하기 위해 그 배관길이에 따라 각 실내 열교환기의 유량 감소를 보정함으로써 쾌적한 냉방을 구현할 수 있는 실내기 설치 위치에 따른 멀티형 에어컨의 운전 방법에 관한 것이다.The present invention relates to a method of operating a multi-type air conditioner according to an indoor unit installation position, and more particularly, in order to prevent the refrigerant flow rate from being reduced when the indoor unit is installed away from the outdoor unit, according to the length of each indoor heat exchanger. The present invention relates to a method of operating a multi-type air conditioner according to an indoor unit installation position capable of realizing comfortable cooling by correcting a flow rate decrease.
일반적인 단배관 멀티형 에어컨은 분지관을 기준으로 용량이 다른 실내기들이 단일 배관에 연결되고, 각 실내 증발기 입구의 전자팽창밸브에 의하여 실내 증발기 입출구 온도차(출구-입구: 이하 과열도라 칭함)를 전자팽창밸브의 개도를 증감 시켜 제어한다.In general single pipe multi-type air conditioner, indoor units having different capacities based on branch pipes are connected to a single pipe, and the evaporator inlet / outlet temperature difference (outlet-inlet: referred to as superheat) Control by increasing or decreasing the degree of opening.
이때, 전자팽창밸브는 주어진 목표과열도(기준치)를 기준으로 개도량을 제어한다. At this time, the electromagnetic expansion valve controls the opening amount based on the given target superheat degree (reference value).
이러한 전자팽창밸브의 냉매 유량을 제어하는 기준이 되는 목표과열도는 실내기의 용량 및 형태에 따라 다르게 설정된다.The target superheat degree, which is a standard for controlling the refrigerant flow rate of the electromagnetic expansion valve, is set differently according to the capacity and shape of the indoor unit.
그러나, 상기와 같이 전자팽창밸브의 목표과열도가 실내기의 용량 및 형태에 의해서만 설정되기 때문에 실내기 위치가 실외기에서 멀리 설치되는 경우에 냉매 유량이 감소하고 목표과열도가 기준치로 안정이 되더라도 실제 열교환기의 입출구 온도가 모두 상승된 상태로 제어되는 문제점이 발생한다.However, since the target superheat of the electromagnetic expansion valve is set only by the capacity and shape of the indoor unit as described above, when the indoor unit position is installed away from the outdoor unit, even though the refrigerant flow rate decreases and the target superheat is stable to the reference value, the actual heat exchanger The problem arises that the inlet and outlet temperatures of are all controlled to rise.
또한, 실내기 설치 위치에 따른 목표과열도 보정이 없기 때문에 냉매유량감소에 의한 냉방 구현이 제대로 실현되지 못하는 문제점이 있다.In addition, since there is no target overheating correction according to the indoor unit installation position, there is a problem in that cooling is not realized properly by reducing the refrigerant flow rate.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 창안된 것으로, 실내기의 위치가 실외기에서 멀리 설치되는 경우 냉매유량이 감소되는 것을 방지하기 위해 그 배관길이에 따라 각 실내 열교환기의 유량 감소를 보정함으로써 쾌적한 냉방을 구현할 수 있는 실내기 설치 위치에 따른 멀티형 에어컨의 운전 방법을 제공하는 데 그 목적이 있다.
The present invention was devised to solve the above-mentioned conventional problems, and the flow rate of each indoor heat exchanger is corrected according to the pipe length to prevent the refrigerant flow rate from being reduced when the indoor unit is installed away from the outdoor unit. The purpose is to provide a method of operating a multi-type air conditioner according to the indoor unit installation location that can implement a comfortable cooling.
상기와 같은 목적을 달성하기 위한 본 발명은 멀티형 에어컨의 운전 제어 방법에 있어서, 상기 멀티형 에어컨의 시운전 시 실외기 압축기의 흡입압력을 측정하고, 상기 측정한 흡입압력과 실내외 온도와 상기 실외기 압축기의 운전 주파수 및 전자팽창밸브의 정격 개도에 따른 기준압력을 비교하여, 상기 흡입압력이 기준압력보다 낮으면 목표과열도를 기준 간격치 만큼 감소시켜 흡입압력이 기준압력보다 높을때까지 운전한 후, 상기 흡입압력이 기준압력보다 높을때 변경된 과열도를 목표과열도로 재 설정하는 것을 특징으로 한다.The present invention for achieving the above object is a method for controlling the operation of a multi-type air conditioner, measuring the suction pressure of the outdoor unit compressor during the commissioning of the multi-type air conditioner, the measured suction pressure and the indoor and outdoor temperature and the operating frequency of the outdoor unit compressor And comparing the reference pressure according to the rated opening of the electromagnetic expansion valve, and if the suction pressure is lower than the reference pressure, reduce the target overheating by the reference interval and operate until the suction pressure is higher than the reference pressure. It is characterized by resetting the changed superheat degree to the target superheat value when it is higher than the reference pressure.

도 1 및 도 2에 도시한 바와 같이, 실외기(10)의 마이컴(11)은 흡입부에 설치된 압력센서(15)로 감지한 압축기(13)의 흡입 압력을 입력 받는다.1 and 2, the microcomputer 11 of the outdoor unit 10 receives the suction pressure of the compressor 13 detected by the pressure sensor 15 installed in the suction unit.
그리고, 실내기(20)의 마이컴(21)은 각 실내기(20)(30)(40)의 열교환기 입출구온도 써미스터(26)(27)가 감지한 실내외 온도조건에 따른 기준 압력을 통신으로 실외기(10)의 마이컴(11)에 전송한다.In addition, the microcomputer 21 of the indoor unit 20 communicates the reference pressure according to the indoor and outdoor temperature conditions sensed by the heat exchanger inlet and outlet temperature thermistors 26 and 27 of each indoor unit 20, 30, 40. To the microcomputer 11 of 10).
이때, 실외기(10)의 마이컴(11)은 압력센서(15)를 통해 감지한 압축기(13)의 흡입 압력과 실내기의 열교환기 입출구온도 써미스터(26)(27)가 감지한 실내외 온도조건에 따른 기준 압력을 비교한다.At this time, the microcomputer 11 of the outdoor unit 10 is based on the suction pressure of the compressor 13 detected by the pressure sensor 15 and the indoor and outdoor temperature conditions detected by the heat exchanger inlet and outlet temperature thermistors 26 and 27 of the indoor unit.

그런 이후에, 본 발명에 의한 멀티형 에어컨 시스템은 압축기의 흡입압력과 실내외 온도조건에 따른 기준 압력의 비교치로 전자팽창밸브(23)의 목표과열도를 재산정하는 것이다.After that, the multi-type air conditioner system according to the present invention is to re-define the target superheat degree of the electromagnetic expansion valve 23 as a comparison value between the suction pressure of the compressor and the reference pressure according to the indoor and outdoor temperature conditions.
더 상세히 설명하면, 사용자가 각 실내기의 주소 설정을 입력하면 실외기의 마이컴은 설정된 주소를 기준으로 실내기의 어드레스를 1,2,3.,,,n 의 실내기로 지정한다.In more detail, when the user inputs the address setting of each indoor unit, the microcomputer of the outdoor unit designates the indoor unit address as 1,2,3. ,, n based on the set address.
그리고, 사용자가 실외기에서 시운전 버튼을 클릭하면, 실외기의 마이컴은 실내기 압력손실판단 명령을 감지하고(S1), 해당 실내기의 저압부 감지를 시작한다(S2).Then, when the user clicks the test drive button on the outdoor unit, the microcomputer of the outdoor unit detects the indoor unit pressure loss determination command (S1) and starts detecting the low pressure part of the indoor unit (S2).
상기 실내기의 저압부 감지를 위해 그 전자팽창밸브는 해당실내기의 정격 개도 및 기준 과열도로 초기 개도를 설정하고, 다른 실내기의 전자팽창밸브를 닫는다(S3).In order to detect the low pressure part of the indoor unit, the electronic expansion valve sets the initial opening degree at the rated opening degree and the reference superheat of the corresponding indoor unit, and closes the electronic expansion valve of the other indoor unit (S3).
실외기는 어드레스 순서에 따라 실내기를 각각 n분간 인버터 압축기의 특정 주파수 X Hz에서 운전 한다(S4).The outdoor unit operates the indoor unit at a specific frequency X Hz of the inverter compressor for n minutes in accordance with the address order (S4).
그리고, 실외기(10)의 마이컴(11)은 흡입부에 설치된 압력센서(15)로 압축기(13)의 흡입 압력을 감지하고, 실내기(20)의 마이컴(21)은 각 실내기(20)(30)(40)의 열교환기 입출구온도 써미스터(26)(27)가 감지한 실내외 온도조건에 따른 기준 압력을 통신으로 실외기(10)의 마이컴(11)에 전송한다(S5).And, the microcomputer 11 of the outdoor unit 10 detects the suction pressure of the compressor 13 by the pressure sensor 15 installed in the suction unit, the microcomputer 21 of the indoor unit 20 is each indoor unit 20, 30 Heat exchanger inlet and outlet temperature of the (40) transmits the reference pressure according to the indoor and outdoor temperature conditions detected by the thermistor (26) (27) to the microcomputer 11 of the outdoor unit (10) (S5).
이때, 실외기(10)의 마이컴(11)은 압력센서(15)를 통해 감지한 압축기(13)의 흡입 압력과 실내기의 열교환기 입출구온도 써미스터(26)(27)가 감지한 실내외 온도조건에 따른 기준 압력을 비교한다(S6).At this time, the microcomputer 11 of the outdoor unit 10 is based on the suction pressure of the compressor 13 detected by the pressure sensor 15 and the indoor and outdoor temperature conditions detected by the heat exchanger inlet and outlet temperature thermistors 26 and 27 of the indoor unit. Compare the reference pressure (S6).
그리고, 에어컨 시스템은 압축기의 흡입압력과 실내외 온도조건에 따른 기준 압력의 비교치가 해당 실내기 기준치보다 작은 경우 목표과열도를 감소시키고, 다시 L분후 압축기의 흡입압력과 기준압력을 비교한다(S7).In addition, the air conditioner system reduces the target superheat when the comparison value between the suction pressure of the compressor and the reference pressure according to the indoor and outdoor temperature conditions is smaller than the indoor unit reference value, and compares the suction pressure and the reference pressure of the compressor after L minutes again (S7).
또한, 상기 흡입압력과 기준압력의 비교치가 해당 실내기 기준치보다 큰 경우에는 목표과열도 보정치를 저장한다(S8).In addition, when the comparison value between the suction pressure and the reference pressure is larger than the indoor unit reference value, the target superheat correction value is stored (S8).
그리고, 실외기의 마이컴은 목표과열도를 산정해야 할 실내기가 더 있는지 여부를 판단하고(S9), 실내기가 더 있는 경우에는 그 해당 실내기에 압력손실판단 명령을 인가하고 해당 실내기의 저압부를 감지(S2)하는 단계로 리턴시키는 것이다(S10).In addition, the microcomputer of the outdoor unit determines whether there are more indoor units to calculate the target superheat degree (S9), and if there are more indoor units, applies a pressure loss determination command to the corresponding indoor units and detects the low pressure part of the indoor unit (S2). To return to the step (S10).
즉, n분간 해당 실내기를 시 운전한 후 압축기의 흡입압력을 감지하고, 실내외 온도 및 운전 주파수, 정격개도에 따른 기준압력과 비교하여 기준 압력보다 낮으면 목표과열도를 기준 간격치 만큼 낮추고, 다시 L 분후 기준압력과 비교후 다시 목표 과열도를 기준 간격치 만큼 낮추던지 또는 기준압력보다 높으면 그때의 변경된 과열도를 목표과열도로 설정한 이후에 그 다음 해당 어드레스의 실내기 운전을 수행 하는 것이다.That is, after operating the indoor unit for n minutes, it detects the suction pressure of the compressor, and if it is lower than the reference pressure compared to the reference pressure according to the indoor and outdoor temperature, operating frequency, and rated opening degree, lowers the target superheat by the reference interval value, and again. After the L-minute comparison with the reference pressure, if the target superheat is lowered by the reference interval or higher than the reference pressure, the changed superheat is set as the target superheat and then the indoor unit operation of the corresponding address is performed.
그리고, 어드레스로 지정된 실내기까지 모든 시운전을 수행하여 전자팽창밸브의 목표과열도 제어를 종료하는 것이다.Then, all the trial runs are performed up to the indoor unit designated by the address, thereby terminating the control of the target superheat of the electromagnetic expansion valve.
상술한 바와 같이, 본 발명은 실내기의 설치 위치에 따른 냉매유량 감소를 보정함으로써 시스템의 냉방성능 효율저하를 방지할 수 있는 잇점이 있다.As described above, the present invention has the advantage that it is possible to prevent the reduction in cooling performance efficiency of the system by correcting the refrigerant flow rate decrease according to the installation position of the indoor unit.
또한, 각 실내기의 설치 위치에 따른 냉매유량감소에 의한 압력저하를 방지하기 위하여 각 실내기의 전자팽창밸브 목표과열도 기준값을 보정하여 시스템의 능동적인 대응이 가능하다.
In addition, in order to prevent the pressure drop due to the decrease in the refrigerant flow rate according to the installation position of each indoor unit, it is possible to actively cope with the system by correcting the reference value of the thermal expansion valve target overheating value of each indoor unit.
