Description

공기조화기의 절전운전 제어방법Control method of power saving operation of air conditioner

본 발명은 공기조화기의 절전운전 제어방법에 관한 것으로, 좀더 상세하게는 사용자가 절전운전모드를 선택하면 압축기 구동시간을 정상운전모드시의 압축기 구동시간 보다 단축함으로써, 공기조화기의 전력 소모를 저감시키는 공기조화기의 절전운전 제어방법에 관한 것이다.The present invention relates to a method for controlling the power saving operation of an air conditioner, and more particularly, when the user selects the power saving operation mode, the compressor operation time is shorter than the compressor operation time in the normal operation mode, thereby reducing power consumption of the air conditioner. It relates to a power saving operation control method of an air conditioner to be reduced.

일반적인 공기조화기의 냉매 사이클은 도 1과 같이 도시할 수 있는데, 상기 도 1에 도시된 실선은 냉방운전시의 냉매 사이클이며, 점선은 난방운전시의 냉매 사이클을 나타낸다.A refrigerant cycle of a general air conditioner may be illustrated as shown in FIG. 1, where a solid line shown in FIG. 1 is a refrigerant cycle in a cooling operation, and a dotted line represents a refrigerant cycle in a heating operation.

즉, 냉방운전시에는 압축기(11)에 의해 고온고압의 기체로 압축된 냉매가 사방밸브(13)를 통해 실외열교환기(15)에 유입되고, 실외열교환기(15)로 유입된 고온고압의 기체냉매가 실외팬(17)이 송풍한 공기에 의해 열교환되어 액화된다.That is, during the cooling operation, the refrigerant compressed by the compressor 11 into the high temperature and high pressure gas flows into the outdoor heat exchanger 15 through the four-way valve 13, and the high temperature and high pressure flows into the outdoor heat exchanger 15. The gas refrigerant is liquefied by heat exchange by the air blown by the outdoor fan 17.

이어서, 상기 실외열교환기(15)에서 액화된 냉매는 바이패스통로(19)와 제1모세관(21)을 통해 저온저압의 액체냉매로 감압되고, 이에 따라, 실내열교환기(23)에서는 상기 제1모세관(21)에서 감압된 저온저압의 냉매를 받아 실내팬(25)에 의해 송풍되는 공기를 냉매의 증발잠열에 의해 열교환하므로써 냉풍을 실내로 토출해서 냉방을 행하고, 상기 실내열교환기(23)에서 출력된 상온저압의 기체냉매는 다시 압축기(11)로 흡입되어 도 1의 실선과 같이 반복순환되는 냉매 사이클을 형성한다.Subsequently, the refrigerant liquefied in the outdoor heat exchanger (15) is decompressed to a low temperature low pressure liquid refrigerant through the bypass passage (19) and the first capillary tube (21). 1 By receiving the low-temperature low-pressure refrigerant depressurized by the capillary tube 21 and exchanging air blown by the indoor fan 25 by the latent heat of evaporation of the refrigerant, the cold air is discharged to the room to perform cooling, and the indoor heat exchanger 23 The gas refrigerant at room temperature and low pressure output from the suction is again sucked into the compressor 11 to form a refrigerant cycle which is repeatedly circulated as shown in FIG. 1.

그리고, 난방운전시에는 압축기(11)에 의해 고온고압의 기체로 압축된 냉매가 사방밸브(13)를 통해 실내열교환기(23)에 유입되면, 실내팬(25)에 의해 송풍되는 공기를 열교환함으로써 난풍을 실내로 토출해서 난방을 행한다.In the heating operation, when the refrigerant compressed by the compressor 11 to the gas of high temperature and high pressure flows into the indoor heat exchanger 23 through the four-way valve 13, the air blown by the indoor fan 25 is exchanged. Thus, warm air is discharged into the room to perform heating.

이어서, 상기 실내열교환기(23)에서 액화된 냉매는 제1 및 제2모세관(21, 27)을 통해 저온저압의 냉매로 감압되고, 이에 따라 실외열교환기(15)에서는 상기 제1 및 제2모세관(21, 27)을 통과하는 저온저압의 냉매를 받아서 실외팬(17)에 의해 송풍되는 공기를 냉매의 증발잠열에 의해 열교환하여 냉각하고, 상기 실외열교환기(15)에서 냉각된 저온저압의 기체 냉매는 다시 압축기(11)로 흡입되어 도 1의 점선과 같이 반복순환되는 냉매 싸이클을 형성한다.Subsequently, the refrigerant liquefied in the indoor heat exchanger (23) is decompressed to the low temperature and low pressure refrigerant through the first and second capillaries (21, 27), and thus the first and second in the outdoor heat exchanger (15). Receives the low temperature low pressure refrigerant passing through the capillaries 21 and 27 and cools the air blown by the outdoor fan 17 by heat exchange by the latent heat of evaporation of the refrigerant, and the low temperature low pressure cooled by the outdoor heat exchanger 15. The gas refrigerant is again sucked into the compressor 11 to form a refrigerant cycle that is repeatedly circulated as shown by the dotted line in FIG.

상기와 같은 냉매 사이클을 가지는 종래의 공기조화기에서 실내온도 변화에 따른 압축기의 "온/오프" 변화는 도 2와 같이 도시할 수 있는데, 상기 도 2에 도시된 실선은 정상운전시의 실내온도 변화 및 이에 따른 압축기의 "온/오프" 변화를 나타낸 것이고, 점선은 절전운전시의 실내온도 변화 및 이에 따른 압축기의 "온/오프" 변화를 나타낸 것이다.In the conventional air conditioner having the refrigerant cycle as described above, the "on / off" change of the compressor according to the change in the room temperature may be shown in FIG. 2, and the solid line shown in FIG. 2 is the change in the room temperature in the normal operation. And according to this change in the "on / off" of the compressor, the dotted line shows the change in the room temperature during the power saving operation and thus the "on / off" change in the compressor.

즉, 정상운전시에는 상기 도 2의 실선으로 나타낸 바와 같이, 압축기가 "온"되면 실내온도가 하강하기 시작하고, 이와 같이 실내온도가 하강하여 실내온도가 사용자가 선택한 설정온도에 도달하면 압축기를 "오프"시킨다.That is, in normal operation, as shown by the solid line of FIG. 2, when the compressor is "on", the indoor temperature starts to decrease. When the indoor temperature drops and the indoor temperature reaches the set temperature selected by the user, the compressor " Off ".

그리고, 상기와 같이 압축기가 "오프"됨에 따라 실내온도가 다시 상승하여 (설정온도+1)℃에 도달하면 다시 압축기를 "온"시켜서 실내온도를 설정온도로 하강시키는 과정을 반복하여 실내온도를 설정온도로 유지시킨다.As the compressor is "off," as described above, when the room temperature rises again and reaches (set temperature + 1) ° C, the compressor is "on" again and the process of lowering the room temperature to the set temperature is repeated. Maintain the set temperature.

한편, 절전운전시에는 상기 도 2의 점선으로 나타낸 바와 같이, 압축기를 "온"되면 실내온도가 하강하기 시작하고, 이와 같이 실내온도가 하강하여 실내온도가 사용자가 선택한 설정온도에 3℃를 더한 온도 즉, (설정온도+3)℃에 도달하면 압축기를 "오프"시킨다.On the other hand, during the power saving operation, as shown by the dotted line in FIG. 2, when the compressor is "on", the room temperature starts to fall, and thus the room temperature decreases, thus adding 3 ° C to the set temperature selected by the user. When the temperature is reached, i.e., (set temperature + 3) ° C, the compressor is "off".

그리고, 상기와 같이 압축기가 "오프"됨에 따라 실내온도가 다시 상승하여 (설정온도+4)℃에 도달하면 다시 압축기를 "온"시켜서 실내온도를 (설정온도+3)℃로 하강시키는 과정을 반복하여 실내온도를 (설정온도+3)℃로 유지시킨다.As described above, when the compressor is "off", when the room temperature rises again and reaches (set temperature +4) ° C, the compressor is "on" again to lower the room temperature to (set temperature +3) ° C. Repeatedly keep the room temperature at (+3) ℃.

그러나, 상기와 같은 종래의 공기조화기의 절전운전 제어방법은, 절전운전모드가 선택되면 사용자가 선택한 설정온도에 소정의 온도를 더한 온도를 기준으로 압축기의 "온/오프"를 수행함에 따라, 사용자가 선택한 설정온도 보다 높은 온도로 실내온도가 유지되므로 사용자가 불쾌감을 느끼게 되는 문제점이 있었다.However, the power saving operation control method of the conventional air conditioner as described above, when the power saving operation mode is selected, by performing the "on / off" of the compressor on the basis of the temperature plus the predetermined temperature selected by the user, Since the indoor temperature is maintained at a temperature higher than the set temperature selected by the user, there is a problem in which the user feels uncomfortable.

따라서, 본 발명은 상기와 같은 종래의 제 문제점을 해소하기 위한 것으로, 압축기의 "온/오프" 듀티(DUTY)를 조정하여 절전운전을 수행하고 압축기의 "온" 듀티를 실내온도상승률이 기준상승률 이상이면 재조정함과 동시에 압축기 "온"시에 실내팬의 풍속을 저풍속으로 제어하여 실내온도의 변화에 따른 사용자의 불쾌감을 줄일 수 있을 뿐만 아니라 전력 소모를 더욱 저감할 수 있는 공기조화기의 절전운전 제어방법을 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above-mentioned problems of the prior art, the power-saving operation is performed by adjusting the "on / off" duty (DUTY) of the compressor, the room temperature rise rate is the reference increase rate of the "on" duty of the compressor If it is abnormal, the air conditioner can be re-adjusted and control the wind speed of the indoor fan at low wind speed when the compressor is “on” to reduce the user's discomfort due to the change of the room temperature and to reduce the power consumption of the air conditioner. The purpose is to provide a method for controlling operation.

이와 같은 목적을 달성하기 위한 본 발명에 따른 공기조화기의 절전운전 제어방법은, 압축기의 "온/오프" 듀티를 조정하여 절전운전을 수행하는 공기조화기의 절전운전 제어방법에 있어서, 공기조화기의 운전조건을 입력하는 운전조건입력단계와, 상기 운전조건에 따라 압축기를 구동시키는 정상운전단계, 절전운전모드가 선택되었는가를 판단하여 절전운전모드가 선택되지 않았으면 상기 정상운전단계를 진행하는 절전운전모드판단단계, 상기 절전운전모드판단단계에서 절전운전모드가 선택되었으면 압축기 "온/오프" 듀티를 결정하는 듀티결정단계, 상기 듀티결정단계에서 결정된 압축기 "온/오프" 듀티에 따라 압축기를 구동시키는 절전운전단계, 압축기가 "온"되었는가를 판단하여 압축기가 "온"되었으면 저풍속으로 실내팬을 구동시키고 압축기가 "오프"되었으면 설정풍속으로 실내팬을 구동시키는 실내팬구동단계 및, 압축기 "오프"시에 실내온도상승률이 기준상승률 이상인가를 판단하여 실내온도상승률이 기준상승률 이상이면 압축기의 "온" 듀티를 증가시킨 다음 상기 절전운전단계를 진행하고 실내온도상승율이 기준상승률 미만이면 압축기의 "온" 듀티를 변화시키지 않고 상기 절전운전단계를 진행하는 듀티재결정단계로 이루어진 것을 특징으로 한다.Energy-saving operation control method of the air conditioner according to the present invention for achieving the above object, in the power-saving operation control method of the air conditioner to perform a power saving operation by adjusting the "on / off" duty of the compressor, air conditioning The operation condition input step of inputting the operation condition of the controller, the normal operation step of driving the compressor according to the operation condition, and whether the power saving operation mode is selected.

단계(S1)에서는 공기조화기에 전원이 인가되면 제어수단(104)이 공기조화기를 초기화시킨 다음 단계(S2)를 진행한다. 즉, 공기조화기에 전원이 인가되면 전원수단(100)은 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 공기조화기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(104)으로 출력하고, 이와 같이 전원수단(100)으로부터 출력되는 직류전압이 제어수단(104)으로 인가되면 제어수단(104)은 공기조화기를 초기화시키는 것이다.In step S1, when power is supplied to the air conditioner, the control means 104 initializes the air conditioner, and then proceeds to step S2. That is, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power supply terminal (not shown) into predetermined DC voltages required for driving the air conditioner, thereby driving each circuit and control means 104. If the DC voltage output from the power supply means 100 is applied to the control means 104, the control means 104 is to initialize the air conditioner.

이어서, 단계(S2)에서는 제어수단(104)이 운전조작수단(102)으로부터 운전시작신호가 입력되었는가를 판단하여 운전조작수단(102)으로부터 운전시작신호가 입력되지 않은 경우에는 공기조화기를 운전대기상태로 유지하고, 운전조작수단(102)으로부터 운전시작신호가 입력되면 단계(S3)를 진행한다.Subsequently, in step S2, the control means 104 determines whether an operation start signal is input from the operation operation means 102, and if the operation start signal is not input from the operation operation means 102, the air conditioner is waiting for operation. It is maintained in the state, and if the driving start signal is input from the driving operation means 102, step S3 is carried out.

이어서, 단계(S3)에서는 사용자가 운전조작수단(102)을 조작하여 공기조화기의 운전모드 및 설정온도 등의 운전조건을 제어수단(104)으로 입력한 다음 단계(S4)를 진행한다.Subsequently, in step S3, the user operates the operation operation means 102 to input operation conditions such as an operation mode and a set temperature of the air conditioner to the control means 104, and then proceeds to step S4.

이어서, 단계(S4)에서는 상기 단계(S3)에서 결정된 운전조건에 따라 제어수단(104)이 공기조화기의 전체 동작을 제어하여 공기조화기를 정상운전시킨 다음 단계(S5)를 진행한다.Subsequently, in step S4, the control means 104 controls the overall operation of the air conditioner according to the operation condition determined in the step S3, and then normally operates the air conditioner, and then proceeds to step S5.

즉, 상기 단계(S4)에서는 도 5에 도시된 정상운전구간에서와 같이, 공기조화기의 정상운전이 시작되면 제어수단(104)이 압축기(134)를 "온"시키도록 제어신호를 압축기구동수단(122)으로 출력하고, 상기 압축기구동수단(122)는 상기 제어수단(104)로부터 입력된 제어신호에 따라 압축기(134)를 "온"시킨다.That is, in the step S4, as in the normal operation section shown in FIG. 5, when the normal operation of the air conditioner starts, the control means 104 drives the control signal to turn on the compressor 134. Output to the means 122, the compressor driving means 122 "turns on" the compressor 134 in accordance with the control signal input from the control means 104.

따라서, 실내온도가 하강하기 시작하고, 이와 같이 실내온도가 하강하여 실내온도가 사용자가 선택한 설정온도에 도달하면 상기 제어수단(104)이 압축기(134)를 "오프"시키도록 제어신호를 압축기구동수단(122)으로 출력하고, 상기 압축기구동수단(122)은 상기 제어수단(104)으로부터 입력된 제어신호에 따라 압축기(134)를 "오프"시킨다.Therefore, when the room temperature starts to fall, and the room temperature falls in this way and the room temperature reaches the set temperature selected by the user, the control means 104 drives the control signal to "off" the compressor 134. Output to the means 122, the compressor drive means 122 "off" the compressor 134 in accordance with the control signal input from the control means 104.

따라서, 실내온도가 다시 상승하고, 이와 같이 실내온도가 상승하여 (설정온도+1)℃에 도달하면 다시 제어수단(104)이 압축기(134)를 "온"시키도록 제어신호를 압축기구동수단(122)으로 출력하고, 상기 압축기구동수단(122)는 상기 제어수단(104)로부터 입력된 제어신호에 따라 압축기(134)를 "온"시키는 과정을 반복하여 실내온도를 설정온도로 유지시킨다.Therefore, when the room temperature rises again and the room temperature rises in this way and reaches (set temperature + 1) ° C., the control means 104 sends the control signal to the compressor driving means so as to “turn on” the compressor 134 again. 122, and the compressor driving means 122 repeats the process of "on" the compressor 134 in accordance with the control signal input from the control means 104 to maintain the room temperature at the set temperature.

이어서, 단계(S5)에서는 제어수단(104)이 운전조작수단(102)으로부터 절전운전모드 선택신호가 입력되었는가를 판단하여 절전운전모드 선택신호가 입력되지 않았으면 상기 단계(S4)를 진행하고, 절전운전모드 선택신호가 입력되었으면 단계(S6)를 진행한다.Subsequently, in step S5, the control means 104 determines whether the power saving operation mode selection signal has been input from the driving operation means 102, and if the power saving operation mode selection signal is not input, proceeds to step S4. If the power saving operation mode selection signal is input, the process proceeds to step S6.

이어서, 단계(S6)에서는 제어수단(104)이 압축기(134)의 "온/오프" 듀티를 결정한 다음 단계(S7)을 진행한다.Subsequently, in step S6, the control means 104 determines the " on / off " duty of the compressor 134 and then proceeds to step S7.

이때, 도 5에 도시된 절전운전 듀티 결정구간에서와 같이, 절전운전시의 압축기(134) "온"시간은 정상운전시 연속하는 2개의 압축기(134) "온"시간의 평균시간에 사용자가 운전조작수단(102)을 통해 입력한 절전운전퍼센트(%)를 곱하여 결정하고, 절전운전시의 압축기(134) "오프"시간은 정상운전시 연속하는 2개의 압축기(134) "오프"시간의 평균시간으로 결정한다.At this time, as in the power saving operation duty determination section shown in FIG. 5, the compressor 134 " on " time in the power saving operation is determined by the user at an average time of two compressor 134 " on " Determined by multiplying the power saving operation percentage (%) input through the operation operation means 102, and the compressor 134 " off " time in the power saving operation is determined by the " off " Determine the average time.

예를 들어, 정상운전시 연속하는 2개의 압축기(134) "온"시간의 평균시간이 5분인 상태에서, 사용자가 운전조작수단(102)을 통해 80%의 절전운전퍼센트를 입력하였으면 절전운전시의 압축기(134) "온"시간은 4분이 되고, 사용자가 운전조작수단(102)을 통해 60%의 절전운전퍼센트를 입력하였으면 절전운전시의 압축기(134) "온"시간은 3분이 되며, 사용자가 운전조작수단(102)을 통해 40%의 절전운전퍼센트를 입력하였으면 절전운전시의 압축기(134) "온"시간은 2분이 되는 것이다.For example, when the average time of two consecutive compressor 134 "on" times during normal operation is 5 minutes, if the user inputs 80% power saving operation percentage through the operation operation means 102, Compressor 134 " on " time is 4 minutes, and if the user inputs 60% power saving operation percentage through the operating operation means 102, compressor " on " time " on " If the user inputs 40% of the power saving operation percentage through the operation operation means 102, the "on" time of the compressor 134 during the power saving operation is 2 minutes.

이어서, 단계(S7)에서는 도 5에 도시된 절전운전구간에서와 같이, 상기 제어수단(104)이 상기 단계(S6)에서 결정된 압축기(134) "온/오프" 듀티에 따라 상기 압축기(134)를 "온" 또는 "오프"시키도록 압축기구동수단(122)으로 제어신호를 출력하고, 상기 압축기구동수단(122)은 상기 제어수단(104)으로부터 입력된 제어신호에 따라 압축기(134)를 "온" 또는 "오프"시킨 다음 단계(S8)을 진행한다.Subsequently, in step S7, as in the power saving operation section shown in FIG. 5, the control means 104 determines the compressor 134 according to the compressor 134 "on / off" duty determined in the step S6. Outputs a control signal to the compressor driving means 122 to "on" or "off", and the compressor driving means 122 operates the compressor 134 according to the control signal input from the control means 104. On "or" off "and then proceed to step S8.

이어서, 단계(S8)에서는 상기 제어수단(104)이 압축기(134)가 "온"되었는가를 판단하여 압축기(134)가 "온"되었으면 단계(S9)을 진행하고, 압축기(134)가 "오프"되었으면 단계(S10)를 진행한다.Subsequently, in step S8, the control means 104 determines whether the compressor 134 is "on", and if the compressor 134 is "on", the process proceeds to step S9, and the compressor 134 is "off". If yes, the process proceeds to step S10.

이어서, 단계(S9)에서는 상기 제어수단(104)이 실내팬모터(138)를 저풍속으로 구동시키도록 제어신호를 실내팬모터구동수단(126)으로 입력하고, 상기 실내팬모터구동수단(126)은 상기 제어수단(104)으로부터 제어신호를 받아서 실내팬모터(138)를 저풍속으로 구동시킨 다음 단계(S7)를 진행한다.Subsequently, in step S9, the control means 104 inputs a control signal to the indoor fan motor driving means 126 to drive the indoor fan motor 138 at a low wind speed, and the indoor fan motor driving means 126. ) Receives the control signal from the control means 104 drives the indoor fan motor 138 at low wind speed, and then proceeds to step S7.

그리고, 단계(S10)에서는 상기 제어수단(104)이 실내팬모터(138)를 사용자가 선택한 설정풍속으로 구동시키도록 제어신호를 실내팬모터구동수단(126)으로 입력하고, 상기 실내팬모터구동수단(126)은 상기 제어수단(104)으로부터 제어신호를 받아서 실내팬모터(138)를 설정풍속으로 구동시킨 다음 단계(S11)을 진행한다.In operation S10, the control means 104 inputs a control signal to the indoor fan motor driving means 126 to drive the indoor fan motor 138 at a set wind speed selected by the user, and drives the indoor fan motor. The means 126 receives the control signal from the control means 104 and drives the indoor fan motor 138 at the set wind speed, and then proceeds to step S11.

즉, 도 5의 절전운전구간에 도시된 바와 같이, 절전운전구간중에 압축기(134)가 "온"되면 실내팬모터(138)가 저풍속으로 구동되고, 압축기(134)가 "오프"되면 실내팬모터(138)가 사용자가 선택한 설정풍속으로 구동되는 것이다.That is, as shown in the power saving operation section of FIG. 5, when the compressor 134 is "on" during the power saving operation section, the indoor fan motor 138 is driven at a low wind speed, and when the compressor 134 is "off", the interior is indoors. The fan motor 138 is driven at the set wind speed selected by the user.

이어서, 단계(S11)에서는 제어수단(104)이 실내온도상승률이 기준상승률 이상인가를 판단하여 실내온도상승률이 기준상승률 이상이면 단계(S12)를 진행하고, 실내온도상승률이 기준상승률 미만이면 압축기(134)의 "온" 듀티를 변화시키지 않고 상기 단계(S7)를 진행한다. 이때, 상기 기준상승률은 1(℃/min.) 즉, 1분당 1℃ 상승으로 결정한다.Subsequently, in step S11, the control means 104 determines whether the indoor temperature increase rate is equal to or higher than the standard increase rate, and proceeds to step S12 when the indoor temperature increase rate is equal to or higher than the reference increase rate. Step S7 is performed without changing the "on" duty of 134). At this time, the reference increase rate is determined as 1 (° C./min.), That is, 1 ° C. rise per minute.

이어서, 단계(S12)에서는 제어수단(104)이 압축기(134)의 "온" 듀티를 증가시킨 다음 상기 단계(S7)을 진행한다.Subsequently, in step S12, the control means 104 increases the "on" duty of the compressor 134 and then proceeds to step S7.

이상에서 살펴본 바와 같이 본 발명에 따르면, 압축기의 "온/오프" 듀티를 조정하여 절전운전을 수행하고 압축기의 "온" 듀티를 실내온도상승률이 기준상승률 이상이면 재조정함과 동시에 압축기 "온"시에 실내팬의 풍속을 저풍속으로 제어하여 실내온도의 변화에 따른 사용자의 불쾌감을 줄일 수 있을 뿐만 아니라 전력 소모를 더욱 저감할 수 있는 효과가 있다.As described above, according to the present invention, the power-saving operation is performed by adjusting the "on / off" duty of the compressor, and when the "on" duty of the compressor is higher than or equal to the standard rising rate, the compressor is "on" at the same time. By controlling the wind speed of the indoor fan to a low wind speed can not only reduce the user's discomfort due to the change in the indoor temperature, but also can further reduce the power consumption.
