본 발명은 공기조화기의 냉방운전시 저온감지에 따른 부하제어방법에 관한 것으로, 특히 저온제어에 있어서 부하(압축기, 실외팬)를 온도대역에 따라 선택적으로 제어하여 실내배관온도를 일정하게 유지토록 하는 공기조화기 부하제어방법에 관한 것이다.The present invention relates to a load control method according to the low temperature detection during the cooling operation of the air conditioner, in particular in the low temperature control to selectively control the load (compressor, outdoor fan) according to the temperature band to maintain the indoor piping temperature constant It relates to an air conditioner load control method.

일반적으로 실내기와 실외기로 구분되는 공기조화기는 냉각싸이클을 통해 발생되는 냉/난기를 제어수단에 설정된 프로그램에 따라 부하를 제어하여 실내를 쾌적한 온도대로 유지하게 된다.In general, the air conditioner, which is divided into an indoor unit and an outdoor unit, controls the load according to a program set in the control unit to cool / heat generated through the cooling cycle to maintain the indoor temperature at a comfortable temperature.

일예로, 공기조화기는 제1도에 도시된 바와같이 실내기(100)와, 실외기(200)로 구분되며, 실내기(100)는 리모콘의 선택 모드를 수신하는 리모콘 수신부(110)와, 실내 흡입온도를 측정하기 위한 실온감지센서(120)와, 실내열교환기 온도를 감지하는 실내배관온도 감지센서(130)와, 실내열교환기에 의해 열교환된 저온의 기류를 실내로 송풍하는 실내팬(140)과, 상기 실온감지센서(120) 및 실내배관온도 감지센서(130)의 감지신호를 근거로 기 설정된 프로그램에 의해 시스템을 제어하는 실내마이컴(150)으로 구성되며; 상기 실외기(200)는 실외 배관온도를 감지하는 실외배관온도 감지센서(210)와, 냉각싸이클의 냉매를 압축시켜 강제적으로 순환시키는 압축기(220)와, 실외열교환기를 냉각시키기 위한 실외팬(230)과, 상기 실내기(100)의 마이컴(150)의 제어신호에 의해 실외기(200)를 제어하는 실외마이컴(240)으로 구성되어 리모컨에 의해 선택된 운전모드에 따라 현재의 실내환경, 실외환경을 근거로 냉각싸이클을 제어하여 소정의 냉방운전을 수행한다.For example, the air conditioner is divided into the indoor unit 100 and the outdoor unit 200, as shown in FIG. 1, the indoor unit 100 is a remote control receiver 110 for receiving the selection mode of the remote control, and the indoor suction temperature Room temperature sensor 120 for measuring the temperature, Indoor pipe temperature sensor 130 for detecting the temperature of the indoor heat exchanger, Indoor fan 140 for blowing the low-temperature air flow heat exchanged by the indoor heat exchanger, It consists of an indoor microcomputer (150) for controlling the system by a predetermined program based on the detection signal of the room temperature sensor 120 and the indoor pipe temperature sensor 130; The outdoor unit 200 includes an outdoor pipe temperature sensor 210 for detecting an outdoor pipe temperature, a compressor 220 for compressing and circulating a refrigerant of a cooling cycle forcibly, and an outdoor fan 230 for cooling an outdoor heat exchanger. And an outdoor microcomputer 240 for controlling the outdoor unit 200 by the control signal of the microcomputer 150 of the indoor unit 100, and based on the current indoor environment and the outdoor environment according to the operation mode selected by the remote controller. The cooling cycle is controlled to perform a predetermined cooling operation.

이와 같이 구성된 종래 공기조화기는 냉방모드시 제2도의 부하제어 그래프와 같이 저온감지조건에 이르게 되면, 압축기와 실외기를 동시에 제어하게 된다. 즉, 압축기가 일정시간 동안 연속적으로 운전하고 있는 상태에서 실내배관온도가 설정온도 이하로 하강할 경우 마이컴(150)에서는 실내열교환기의 결빙을 방지하기 위해 설정된 프로그램에 따라 저온동작 조건으로 판단하여 압축기(220)와 실외팬(230)을 동시에 정지시켜 실내배관온도를 상승시키고, 반대로 실내배관온도가 설정온도 이상으로 상승할 경우 상기 압축기(220)와 실외팬(230)을 구동시켜 실내배관온도의 상승을 방지하게 된다.The conventional air conditioner configured as described above controls the compressor and the outdoor unit simultaneously when the low temperature sensing condition is reached as shown in the load control graph of FIG. 2 in the cooling mode. That is, if the indoor piping temperature drops below the set temperature while the compressor is continuously running for a predetermined time, the microcomputer 150 determines the low temperature operating condition according to a program set to prevent freezing of the indoor heat exchanger. At the same time, the indoor pipe temperature is increased by simultaneously stopping the 220 and the outdoor fan 230, and when the indoor pipe temperature rises above the set temperature, the compressor 220 and the outdoor fan 230 are driven to maintain the indoor pipe temperature. It will prevent the rise.

그러나 상기한 부하제어방법은 냉방모드시 실내배관온도에 따라 압축기와 실외팬을 동시에 제어할 경우 실내환경, 실외환경 또는 제품 특성에 따라 저온동작모드를 자주 반복하기 때문에 압축기 운전율이 저하될 뿐만 아니라 압축기 초기 기동 소음이 자주 발생하게 되며, 압축기의 반복운전이 지속될 경우에는 실내열교환기 표면에 결빙층이 누적되어 냉방 효율이 감소되는 문제점이 있다.However, in the load control method, when the compressor and the outdoor fan are simultaneously controlled in accordance with the indoor piping temperature in the cooling mode, the low temperature operation mode is repeatedly repeated according to the indoor environment, the outdoor environment, or the product characteristics. Compressor initial start-up noise is frequently generated, and if the repeated operation of the compressor is continued, there is a problem in that the cooling efficiency is reduced by accumulating a layer of ice on the surface of the indoor heat exchanger.

본 발명은 이러한 문제점을 해결하기 위해 안출된 것으로, 특히 냉방모드시 압축기를 정지시키지 않고 실외팬을 제어하여 실내배관온도를 조절함으로써 압축기 운전효율을 높임과 동시에 냉방 효율을 증대시키도록 하는 공기조화기의 부하 제어방법을 제공하는데 목적이 있다.The present invention has been made to solve the above problems, in particular, the air conditioner to increase the cooling efficiency and increase the cooling efficiency at the same time by controlling the indoor piping temperature by controlling the outdoor fan without stopping the compressor in the cooling mode The purpose is to provide a load control method.

이러한 목적을 달성하기 위한 본 발명의 공기조화기 부하제어방법은 저온감지조건에 따라 압축기와 실외팬을 제어하는 제어수단이 구비된 공기조화기에 있어서, 냉방/제습시 압축기가 일정시간 동안 정지된 상태에서 실내배관온도가 설정온도(T4℃) 보다 높을 경우 압축기와 실외팬을 동시에 구동시키는 부하동시구동단계와; 일정시간 동안 압축기가 연속적으로 운전되고 실내배관온도가 설정온도(T1℃)보다 낮을 경우 압축기와 실외팬을 동시에 정지시키는 부하동시정지단계와; 압축기의 연속운전과 관계없이 실내배관온도가 설정온도(T1℃)와 설정온도(T4℃) 범위내에서 변화가 있을 경우 실외팬만을 선택적으로 제어하는 부하선택제어단계;를 수행함을 특징으로 한다.In the air conditioner load control method of the present invention for achieving the above object, in the air conditioner equipped with a control means for controlling the compressor and the outdoor fan according to the low temperature detection condition, the compressor is stopped for a predetermined time during cooling / dehumidification A simultaneous load driving step of simultaneously driving the compressor and the outdoor fan when the indoor piping temperature is higher than the set temperature (T4 ° C.); A load simultaneous stop step of simultaneously stopping the compressor and the outdoor fan when the compressor is continuously operated for a predetermined time and the indoor piping temperature is lower than the set temperature (T1 ° C.); And a load selection control step of selectively controlling only the outdoor fan when the indoor piping temperature changes within a set temperature (T1 ° C.) and a set temperature (T4 ° C.) regardless of the continuous operation of the compressor.

상기 부하선택제어단계는 실내배관온도가 설정온도(T1℃)보다 높고 설정온도(T2℃)보다 낮을 경우 실외팬을 일시적으로 정지시켜 실내배관온도를 상승시키는 온도상승단계와; 실내배관온도가 설정온도(T4℃)보다 낮고 설정온도(T3℃)보다 높을 경우 실외팬을 구동시켜 실내배관온도를 하강시키는 온도하강단계;를 수행함을 특징으로 한다.The load selection control step includes: a temperature raising step of increasing the indoor piping temperature by temporarily stopping the outdoor fan when the indoor piping temperature is higher than the set temperature (T1 ° C.) and lower than the set temperature (T2 ° C.); When the indoor piping temperature is lower than the set temperature (T4 ℃) and higher than the set temperature (T3 ℃) the temperature falling step of lowering the indoor piping temperature by driving the outdoor fan.

상기 온도상승단계에서 실외팬을 정지시켜 실내배관온도가 설정온도(T3℃)에 도달하지 않더라도 일정시간이 경과하면 실외팬을 구동시키도록 함을 특징으로 한다.The outdoor fan is stopped in the temperature rising step so that the outdoor fan is driven after a predetermined time even if the indoor piping temperature does not reach the set temperature (T3 ° C.).

이러한 방법에 의한 본 발명의 부하제어방법은 압축기의 연속운전과 관계없이 실내배관온도가 일정온도범위에서 변화를 거듭할 경우 실외팬만을 제어하여 실내배관온도를 조절할 수 있어 압축기의 운전효율을 높일 수 있다.The load control method of the present invention by the above method can increase the operating efficiency of the compressor by controlling the indoor piping temperature only by controlling the outdoor fan when the indoor piping temperature changes in a certain temperature range regardless of the continuous operation of the compressor. have.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 통해 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 공기조화기의 전기적인 연결구성은 제1도의 종래 기술구성과 동일하며, 다만 실내배관온도대에 따라 부하를 선택적으로 제어하는 방법이 구별된다.The electrical connection configuration of the air conditioner of the present invention is the same as the prior art configuration of FIG. 1, except that the method for selectively controlling the load according to the indoor piping temperature zone is distinguished.

즉, 종래에는 연속적으로 압축기가 운전하고 있는 상태에서 실내배관온도에 따라 부하를 제어하였지만, 본 발명은 제3도의 부하제어 그래프와 같이 압축기의 운전시간과 관계없이 실내배관온도가 설정온도 범위내에서 변화할 경우 실외팬을 제어하여 실내배관온도를 조절함으로써 가급적 시스템 운전중 압축기 정지 횟수를 줄여 냉방효율을 향상시키고자 하는 것으로, 이를 제4도의 플로우챠트도를 통해 설명한다.That is, in the past, the load was controlled according to the indoor piping temperature while the compressor was continuously running. However, in the present invention, as shown in the load control graph of FIG. 3, the indoor piping temperature is within the set temperature range regardless of the operation time of the compressor. In order to improve the cooling efficiency by reducing the number of compressor stops during system operation as much as possible by controlling the indoor piping temperature by controlling the outdoor fan, this will be described with reference to the flowchart of FIG.

본 발명은 초기에 공기조화기의 운전모드를 판단하여 냉방/제습모드가 아니면 저온감지 초기제어 플래그를 클리어 시키고 반대로 냉방/제습모드이면 압축기의 운전여부를 판단하게 된다.(S1-S3)The present invention initially determines the operation mode of the air conditioner to clear the low temperature detection initial control flag if not the cooling / dehumidification mode, and conversely, the operation of the compressor is determined in the cooling / dehumidification mode. (S1-S3)

만약, 압축기(220)가 정지상태에서 3분이 지연되거나 실내배관온도가 T4℃(제품이 저온감지 조건에서 정지되었던 압축기를 재운전시키기 위한 기준온도 데이터)미만일 경우 리턴하고, 압축기(220)가 정지되어 3분이 경과한 상태에서 실내배관온도가 T4℃보다 낮을 경우에는 압축기(220)와 실외팬(230)을 구동시킨다.(S4-S7)If the compressor 220 is delayed for 3 minutes or the indoor piping temperature is less than T4 ° C. (reference temperature data for restarting the compressor in which the product has been stopped at a low temperature sensing condition), the compressor 220 returns and the compressor 220 stops. If the indoor piping temperature is lower than T4 ℃ in the state that 3 minutes has elapsed, the compressor 220 and the outdoor fan 230 is driven. (S4-S7)

반대로, 압축기가 일정시간 동안 연속적으로 구동된 상태에서 실내배관온도가 설정온도 T1℃(제품의 저온감지 조건인지 판단하여 압축기를 정지시키기 위한 기준온도 데이터)보다 낮을 경우에는 마이컴(150)에서는 실외온도가 낮아 실외열교환기를 통과하는 열매체의 온도가 낮은 것으로 판단하여 압축기(220)와 실외팬(230)을 동시에 정지(S8-S11)시킴으로써 실외열교환기를 통과하는 열매체의 온도를 상승시켜 실내열교환기를 통과하는 열매체의 온도를 상승시킨다.On the contrary, if the indoor piping temperature is lower than the set temperature T1 ° C (reference temperature data for stopping the compressor by determining whether it is a low temperature sensing condition of the product) while the compressor is continuously operated for a predetermined time, the microcomputer 150 uses the outdoor temperature. It is determined that the temperature of the heat medium passing through the outdoor heat exchanger is low because the temperature of the heat medium passing through the outdoor heat exchanger is increased by stopping the compressor 220 and the outdoor fan 230 simultaneously (S8-S11). Raise the temperature of the heating medium.

상기한 부하제어방법은 종래와 동일하며, 본 발명은 압축기의 정지와 구동을 결정하는 실내배관온도 즉, 프로그램상에 설정된 설정온도 T1℃과 T4℃의 사이의 온도대역을 세분화함으로써 목적하는 바 부하를 선택적으로 제어하게 된다.The load control method described above is the same as in the related art, and the present invention provides the desired bar load by subdividing the indoor piping temperature that determines the stop and operation of the compressor, that is, the temperature band between the set temperature T1 ° C. and T4 ° C. Will be controlled selectively.

즉, 저온감지 초기제어세팅 여부를 판단(S12)하여 저온감지 초기제어가 세팅되지 않았을 경우에 마이컴(150)에서는 실내배관온도를 감지하여 기설정된 온도와 비교 판단하게 되는데, 실내배관온도가 T2℃(T1℃ T2℃)보다 높을 경우에는 리턴하고, 반대로 실내배관온도가 T2℃보다 낮을 경우 즉, 실내배관온도가 하강하여 압축기가 정지되는 전단계의 온도대에 도달하면 저온감지 초기제어를 세트시킴과 동시에 압축기(220)는 정상적으로 구동시키면서 실외팬(230)만을 정지시켜 실내배관온도를 상승시키게 된다.(S13-S16)That is, when the initial detection of low temperature detection is not set (S12), when the initial detection of low temperature detection is not set, the microcomputer 150 detects the indoor piping temperature and compares it with the preset temperature. The indoor piping temperature is T2 ° C. If it is higher than (T1 ℃ T2 ℃), it returns. On the contrary, if the indoor piping temperature is lower than T2 ℃, that is, when the indoor piping temperature drops and reaches the temperature range of the previous stage where the compressor is stopped, the initial control of low temperature detection is set. At the same time, the compressor 220 stops only the outdoor fan 230 while driving normally, thereby increasing the indoor piping temperature. (S13-S16)

한편, 저온감지 초기제어가 세팅된 상태에서 실내배관온도가 설정온도 T3℃(T2℃ T3℃)보다 높을 경우에는 저온감지 초기제어를 클리어시킴과 동시에 정지된 실외팬(230)을 구동시켜 실내배관온도를 하강시키며, 반대로 실내배관온도가 설정온도 T3℃보다 낮을 경우에는 실외팬이 정지된 이후 설정시간이 경과하면 실외팬을 구동(S17-S20)시킴으로써 가능한 압축기를 제어하지 않고 실외팬만으로 실내배관온도를 조절할 수 있다.On the other hand, when the indoor piping temperature is higher than the set temperature T3 ° C (T2 ° C T3 ° C) in the state where the low-temperature detection initial control is set, the low-temperature detection initial control is cleared and the stopped outdoor fan 230 is driven to indoor piping. On the contrary, if the indoor piping temperature is lower than the set temperature T3 ℃, if the set time has elapsed after the outdoor fan is stopped, the outdoor fan is driven (S17-S20). The temperature can be adjusted.

이상에서 설명한 바와 같이 본 발명은 압축기와 실외팬을 제어할 수 있는 실내배관온도대를 마이컴에 세분화시켜 저장하고 실내배관온도가 일정한 범위내에서 상승과 하강을 반복할 경우 압축기를 제어하지 않고 실외팬만을 제어하여 실내배관온도로 조절함으로써 시스템의 잦은 저온동작을 방지하여 압축기의 운전율을 향상시킬 수 있게 되며, 이와 동시에 실내열교환기의 결빙을 방지할 수 있게 된다.As described above, the present invention divides and stores the indoor piping temperature zone that can control the compressor and the outdoor fan in the microcomputer and the outdoor fan without controlling the compressor when the indoor piping temperature is repeatedly raised and lowered within a certain range. By controlling only the indoor piping temperature by controlling the bay, it is possible to prevent frequent low-temperature operation of the system to improve the operation rate of the compressor, and at the same time prevent freezing of the indoor heat exchanger.
