Valve 35 and an outdoor heat exchanger 40 for condensing the gas refrigerant compressed by the high temperature and high pressure in the compressor 30 at the time of cooling operation with air blown by the outdoor fan 41 to cool and condense the liquid refrigerant with low temperature and high pressure. ), A capillary tube 50 for expanding under reduced pressure into a low-temperature, low-pressure free refrigerant which is easy to evaporate, and a refrigerant liquefied in an indoor heat exchanger which will be described later in the heating operation.

또한, 상기 실내기(10)에는 냉방운전시 상기 모세관(50)을 통과한 저온저압의 무상냉매를 실내팬(81)에 의해 송풍되는 공기로 열교환하여 증발시키면서 저온저압의 완전 기체상태의 냉매가스로 변환시키는 실내열교환기(80)가 설치되어 있다.In the indoor unit 10, the low-temperature low-pressure free refrigerant passing through the capillary tube 50 during the cooling operation is exchanged with air blown by the indoor fan 81 to evaporate as a low-temperature low-pressure completely gaseous refrigerant gas. An indoor heat exchanger 80 for converting is provided.
상기와 같이 구성된 공기조화기의 냉방운전시에는 사방밸브(35)가 오프되어 냉매가 도 1의 실선화살표 방향으로 도시한 바와같이, 압축기(30)→ 사방밸브(35)→ 실외열교환기(40)→ 한방향밸브(70)→ 모세관(50)→ 실내열교환기(80)→ 사방밸브(35)→ 압축기(30)순으로 순환되는 냉매싸이클을 형성한다.During the cooling operation of the air conditioner configured as described above, the four-way valve 35 is turned off, and the refrigerant is shown in the direction of the solid arrow in FIG. 1, and the compressor 30 → the four-way valve 35 → the outdoor heat exchanger 40. ?) One-way valve 70 → capillary tube 50 → indoor heat exchanger 80 → four-way valve 35 → compressor 30 to form a refrigerant cycle.
반면, 난방운전시에는 사방밸브(35)가 온되어 냉매가 도 1의 점선화살표 방향으로 도시한 바와같이, 압축기(30)→ 사방밸브(35)→ 실내열교환기(80)→ 모세관(50)→ 난방용 모세관(60)→ 실외열교환기(40)→ 사방밸브(35)→ 압축기(30)순으로 순환되는 냉매싸이클을 형성한다.On the other hand, during the heating operation, the four-way valve 35 is turned on so that the refrigerant is shown in the direction of the dotted arrow in FIG. 1, such as the compressor 30 → the four-way valve 35 → the indoor heat exchanger 80 → the capillary tube 50. → a refrigerant cycle circulated in the order of the heating capillary 60 → the outdoor heat exchanger 40 → the four-way valve 35 → the compressor 30.
상기와 같은 냉매싸이클을 형성하여 냉난방운전을 행하는 공기조화기에 있어서, 사용자가 도시되지 않은 리모콘이나 실내기(10)의 콘트롤판넬상에 구비된 키조작부를 조작하여 운전/정지키(이하, 운전키라 한다)를 누른다음 원하는 운전모드(예를들면, 자동)와 설정온도(Ts) 및 설정풍량을 입력하면, 실내기(10)가 운전을 시작하는데, 먼저 실내팬(81)이 설정풍량에 따라 회전하여 실내공기가 실내기(10)내로 흡입되기 시작한다.In the air conditioner for cooling and heating operation by forming the refrigerant cycle as described above, the user operates the key operation unit provided on the control panel of the remote controller or the indoor unit 10 (not shown). After pressing), input the desired operation mode (for example, automatic), the set temperature (Ts) and the set air volume, the indoor unit 10 starts to operate, and first, the indoor fan 81 rotates according to the set air volume. Indoor air begins to be sucked into the indoor unit (10).
이때, 실내기(10)내로 흡입되는 실내공기의 온도를 실내기(10)내의 도시되지 않은 온도센서에서 감지하면, 실내기(10)에서는 설정온도(Ts)와 실내온도(Tr)를 비교하여 실내온도(Tr)가 설정온도(Ts)보다 높은 경우 도 2에 도시한 바와같이, 압축기(30)를 온시킨다.At this time, when the temperature of the indoor air sucked into the indoor unit 10 is detected by a temperature sensor (not shown) in the indoor unit 10, the indoor unit 10 compares the set temperature Ts with the room temperature Tr to determine the room temperature ( When Tr is higher than the set temperature Ts, the compressor 30 is turned on as shown in FIG.
상기 압축기(30)가 온되면, 도 1의 실선화살표 방향으로 냉매싸이클이 이루어지는데, 먼저 실외기(20)의 압축기(30)로부터 토출된 고온고압의 기체냉매가 사방밸브(35)를 통해 실외열교환기(40)에 유입되면, 상기 실외열교환기(40)에서는 고온고압으로 압축된 기체냉매를 실외팬(41)에 의해 송풍되는 공기로 열교환하여 강제냉각시켜 응축시키고, 상기 실외열교환기(40)에서 응축된 저온고압의 액상냉매는 한방향밸브(70)를 거쳐 모세관(50)으로 유입된다.When the compressor 30 is turned on, a refrigerant cycle is made in the solid arrow direction of FIG. 1. First, the high-temperature, high-pressure gas refrigerant discharged from the compressor 30 of the outdoor unit 20 is exchanged for outdoor heat through the four-way valve 35. When the gas is introduced into the gas 40, the outdoor heat exchanger 40 exchanges the gas refrigerant compressed at high temperature and high pressure with air blown by the outdoor fan 41, forcibly cools it, and condenses it. The liquid refrigerant of low temperature and high pressure condensed in is introduced into the capillary tube 50 through the one-way valve 70.
상기 모세관(50)으로 유입된 저온고압의 액상냉매는 증발하기쉬운 저온저압의 무상냉매로 팽창되어 실내기(10)내에 설치된 실내열교환기(80)로 유입되고, 상기 실내열교환기(80)에서는 모세관(50)을 통해 감압된 저온저압의 무상냉매가 여러개의 파이프를 통과하면서 증발하여 기화할때 실내팬(81)에 의해 송풍되는 공기에서 열을 빼앗아 실내공기를 냉각시킨다음, 그 냉각된 공기(냉풍)를 실내로 토출해서 자동냉방운전을 행하고, 상기 실내열교환기(80)에서 냉각된 저온저압의 기체냉매는 다시 압축기(30)로 유입되어 압축기(30)의 단열압축작용에 의해 고온고압의 냉매가스로 변환되어 위에서 설명한 냉매싸이클을 반복한다.The low temperature and high pressure liquid refrigerant introduced into the capillary tube 50 is expanded into a low temperature low pressure free refrigerant which is easy to evaporate and flows into the indoor heat exchanger 80 installed in the indoor unit 10, and the capillary tube in the indoor heat exchanger 80. When the low-temperature, low-pressure free refrigerant depressurized through the 50 passes through several pipes and evaporates and vaporizes, it cools the indoor air by taking heat from the air blown by the indoor fan 81, and cooling the indoor air. Cold air) is discharged into the room to perform the automatic cooling operation, and the low-temperature low-pressure gas refrigerant cooled by the indoor heat exchanger 80 flows into the compressor 30 again and is subjected to high temperature and high pressure by the adiabatic compression action of the compressor 30. The refrigerant cycle is converted and the refrigerant cycle described above is repeated.
상기와 같이 자동운전이 일정시간 수행되면, 실내공기의 온도가 점차 낮아지므로 이때의 변화하는 실내온도(Tr)를 감지하여 실내온도(Tr)가 설정온도(Ts)에 도달하면 도 2에 도시한 바와같이, 압축기(30)를 오프시킨다.When the automatic operation is performed as described above for a predetermined time, the temperature of the indoor air is gradually lowered, and thus, when the indoor temperature Tr reaches the set temperature Ts by detecting the changing room temperature Tr at this time, it is shown in FIG. As shown, the compressor 30 is turned off.
상기 압축기(30)가 오프됨에 따라 실내공기의 온도(Tr)가 점차 높아져 실내온도(Tr)가 설정온도(Ts) + 1℃에 도달하면 도 2에 도시한 바와같이, 압축기(30)를 다시 온시켜 실내온도(Tr)를 설정온도(Ts)로 낮추는 과정을 반복하여 실내온도(Tr)를 설정온도(Ts)로 유지시킨다.As the compressor 30 is turned off, the temperature Tr of the indoor air is gradually increased, and when the room temperature Tr reaches the set temperature Ts + 1 ° C., as shown in FIG. 2, the compressor 30 is again turned on. By repeating the process of lowering the room temperature Tr to the set temperature Ts by turning on, the room temperature Tr is maintained at the set temperature Ts.
그런데, 이와같이 구성된 종래의 공기조화기에 있어서는, 실내온도(Tr)를 사용자가 입력한 설정온도(Ts)로 유지시키기 위하여 실내온도(Tr)의 변화에 따라 압축기(30)의 온/오프가 자주 발생하므로 운전효율이 떨어지고, 압축기(30) 온/오프시 순간적인 운전전류가 급상승하여 소비전력이 증가한다는 문제점이 있었다.However, in the conventional air conditioner configured as described above, in order to maintain the room temperature Tr at the set temperature Ts input by the user, the compressor 30 is frequently turned on / off in accordance with the change of the room temperature Tr. Therefore, there is a problem in that the operating efficiency is lowered, the instantaneous operating current suddenly increases when the compressor 30 is turned on / off and power consumption increases.
따라서, 본 발명은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로, 일정시간동안의 압축기 온/오프시간을 평균한 값을 백분율(%)화 한다음, 실내온도 및 설정온도의 차에 따라 카오스연산을 실행하여 결정된 카오스가중치에 따라 압축기 온시간을 5단계의 백분율 값(절전운전율)으로 제어하여 압축기의 온시간을 단축하므로 운전소비전력을 감소시켜 절전효과를 높이는 공기조화기의 절전운전 제어장치 및 그 방법을 제공하는데 있다.Accordingly, the present invention has been made in order to solve the above-mentioned conventional problems, and a percentage (%) of the average value of the compressor on / off time for a predetermined time is converted into a chaos according to the difference between the room temperature and the set temperature. According to the chaos weight determined by the calculation, the compressor on time is controlled by a percentage value of 5 stages (power saving operation rate) to shorten the on time of the compressor, thereby reducing the power consumption of the air conditioner. An apparatus and a method thereof are provided.

And control means for controlling the compressor on time according to the chaos weight determined by the difference between the room temperature and the set temperature, and compressor driving means for driving the compressor according to the control signal from the control means. It is done.

본 발명에 의한 공기조화기의 냉매싸이클도는 도 1에 도시한 종래의 구성과 동일하므로 동일명칭 및 동일부호를 명기하여 중복되는 설명을 생략한다.Since the refrigerant cycle diagram of the air conditioner according to the present invention is the same as the conventional configuration shown in Fig. 1, the same name and the same reference numerals are specified to omit overlapping descriptions.
도 3에 도시한 바와같이, 전원수단(100)은 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 공기조화기의 동작에 필요한 소정의 직류전압으로 변환하여 출력하고, 운전조작수단(102)은 공기조화기의 운전모드(자동, 냉방, 제습, 송풍, 난방 등)와 설정풍량, 설정온도(Ts)를 입력하는 다수의 기능키를 구비함은 물론, 상기 공기조화기의 운전/정지를 입력하는 운전키와, 절전운전/절전운전정지를 입력하는 절전운전키를 구비하고 있다.As shown in FIG. 3, the power supply means 100 converts a commercial AC voltage supplied from an AC power supply terminal (not shown) into a predetermined DC voltage necessary for the operation of the air conditioner, and outputs the same.

The compressor 30 is driven according to the compressor 30 on time adjusted to a rate (for example, 90%, 80%, 70%, 60%, 50%).
실외팬모터구동수단(112)은 상기 운전조작수단(102)에 의해 사용자가 설정한 온도(Ts) 및 상기 실내온도감지수단(106)에 의해 감지된 실내온도(Tr)의 비교결과에 따라 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 상기 실외열교환기(40)에서 열교환된 공기를 실외로 송풍하도록 실외팬모터의 회전수를 제어하여 실외팬(41)을 구동제어한다.The outdoor fan motor driving means 112 is configured according to a comparison result of the temperature Ts set by the user by the driving operation means 102 and the indoor temperature Tr sensed by the indoor temperature sensing means 106. The outdoor fan 41 is driven by controlling the rotation speed of the outdoor fan motor to receive the control signal output from the control means 104 and blow the air heat exchanged by the outdoor heat exchanger 40 to the outside.
또, 실내팬모터구동수단(114)은 상기 운전조작수단(102)에 의해 사용자가 설정한 풍량에 따라 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 상기 실내열교환기(80)에서 열교환된 공기(냉풍 또는 온풍)를 실내로 송풍하도록 실내팬모터의 회전수를 제어하여 실내팬(81)을 구동제어한다.In addition, the indoor fan motor driving means 114 receives the control signal output from the control means 104 in accordance with the air volume set by the user by the operation operation means 102 is heat exchanged in the indoor heat exchanger (80) The indoor fan 81 is driven and controlled by controlling the rotation speed of the indoor fan motor to blow air (cold or warm air) into the room.
또한 도면에 있어서, 표시수단(116)은 상기 제어수단(104)의 제어에 따라 상기 운전조작수단(102)에 의해 입력된 운전선택모드(자동, 냉방, 제습, 송풍, 난방, 절전 등)를 표시함은 물론, 상기 공기조화기의 운전상태를 표시한다.In addition, in the drawing, the display means 116 displays the operation selection mode (automatic, cooling, dehumidifying, blowing, heating, power saving, etc.) input by the driving operation means 102 under the control of the control means 104. The display, as well as the operating state of the air conditioner.
이하, 상기와 같이 구성된 공기조화기의 절전운전 제어장치 및 그 방법의 작용효과를 설명한다.Hereinafter, the operation and effect of the power saving operation control device and method of the air conditioner configured as described above will be described.
도 4는 본 발명에 의한 공기조화기의 절전운전 제어동작순서를 도시한 플로우챠트로써, 도 4에서 S는 스텝(STEP)을 표시한다.FIG. 4 is a flowchart showing a procedure for controlling the power saving operation of the air conditioner according to the present invention, in which S denotes a step.
먼저, 공기조화기에 전원이 인가되면, 전원수단(100)에서는 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 공기조화기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(104)에 출력한다.First, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 104).
따라서, 스텝S1에서는 상기 전원수단(100)으로부터 출력되는 직류전압을 제어수단(104)에서 입력받아 공기조화기를 초기화시킨다.Therefore, in step S1, the DC voltage output from the power supply means 100 is input from the control means 104 to initialize the air conditioner.
이때, 사용자가 운전조작수단(102)을 조작하여 운전키를 누른다음 원하는 공기조화기의 운전모드와 설정온도(Ts), 설정풍량을 입력하면, 운전조작수단(102)으로부터 운전시작신호(이하, 운전신호라 한다)와 운전선택신호가 제어수단(104)에 입력된다.At this time, when the user operates the operation operation means 102 and presses the operation key, and inputs the operation mode, the set temperature Ts, and the set air volume of the desired air conditioner, the operation start signal (hereinafter referred to as the following). , An operation signal) and an operation selection signal are input to the control means 104.
이에 따라, 스텝S2에서 제어수단(104)은 상기 운전조작수단(102)으로부터 운전신호가 입력되었는지를 판별하여, 운전신호가 입력되지 않은 경우(NO일 경우)에는 공기조화기를 운전대기상태로 유지하면서 스텝S2이하의 동작을 반복수행한다.Accordingly, in step S2, the control means 104 determines whether the driving signal is input from the driving operation means 102, and maintains the air conditioner in the operation standby state when the driving signal is not input (NO). The operation of step S2 and below is repeated.
상기 스텝S2에서의 판별결과, 운전신호가 입력된 경우(YES일 경우)에는 스텝S3으로 나아가서 제어수단(104)은 설정온도(Ts)에 따라 실내온도(Tr)를 제어하여 도 5에 도시된 정상운전구간에서와 같이, 공기조화기를 정상운전시킨다.As a result of the discrimination in step S2, when the operation signal is input (YES), the control means 104 controls the room temperature Tr according to the set temperature Ts, as shown in FIG. As in the normal operating section, operate the air conditioner normally.
즉, 상기 제어수단(104)에서 설정온도(Ts)와 실내온도(Tr)를 비교하여 실내온도(Tr)가 설정온도(Ts)보다 높으면 압축기(30)를 온시키도록 압축기구동수단(110)에 제어신호를 출력하고, 상기 압축기구동수단(110)에서는 제어수단(104)으로부터 출력되는 제어신호를 받아서 압축기(30)를 온시킨다.That is, the compressor driving means 110 turns on the compressor 30 when the indoor temperature Tr is higher than the set temperature Ts by comparing the set temperature Ts and the room temperature Tr in the control means 104. The control signal is output to the compressor driving means 110, and the compressor 30 receives the control signal output from the control means 104 to turn on the compressor 30.
상기 압축기(30)가 온됨에 따라 실내공기의 온도(Tr)가 점차 낮아져 실내온도(Tr)가 설정온도(Ts)에 도달하면 압축기구동수단(110)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 압축기(30)를 오프시킨다.As the compressor 30 is turned on, when the temperature Tr of the indoor air is gradually lowered and the room temperature Tr reaches the set temperature Ts, the compressor driving means 110 outputs a control signal output from the control means 104. Receives the input to turn off the compressor (30).
상기 압축기(30)가 오프됨에 따라 실내공기의 온도(Tr)가 점차 높아져 실내온도(Tr)가 설정온도(Ts) + 1℃에 도달하면 압축기구동수단(110)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 압축기(30)를 다시 온시켜 실내온도(Tr)를 설정온도(Ts)로 낮추는 과정을 반복하여 실내온도(Tr)를 설정온도(Ts)로 유지시킨다.As the compressor 30 is turned off, the temperature Tr of the indoor air gradually increases, and when the room temperature Tr reaches the set temperature Ts + 1 ° C., the compressor driving means 110 outputs from the control means 104. The control unit 30 receives the control signal, and the compressor 30 is turned on again to repeat the process of lowering the room temperature Tr to the set temperature Ts to maintain the room temperature Tr at the set temperature Ts.
상기와 같은 정상운전시에, 스텝S4에서는 운전조작수단(102)의 절전운전키가 온되어 운전조작수단(102)으로부터 제어수단(104)에 절전운전신호가 입력되었는지를 판별하여, 절전운전신호가 입력되지 않은 경우(NO일 경우)에는 상기 스텝S3으로 복귀하여 스텝S3이하의 동작을 반복수행한다.In the normal operation as described above, in step S4, the power saving operation key of the driving operation means 102 is turned on to determine whether the power saving operation signal is input from the operation operation means 102 to the control means 104, and the power saving operation signal is generated. If no input is made (NO), the flow returns to step S3 to repeat the operation of step S3 and below.
상기 스텝S4에서의 판별결과, 절전운전신호가 입력된 경우(YES일 경우)에는 스텝S5로 나아가서 제어수단(104)은 도 5에 도시된 데이터산출구간에서와 같이, 실내온도(Tr)의 변화에 의해 압축기(30)의 온/오프를 제어하는 정상운전을 소정시간(데이터산출구간)동안 행하면서 압축기(30) 온/오프시간을 평균하여 나온 압축기(30) 온/오프시간의 평균데이터를 산출한다.As a result of the discrimination in step S4, when the power saving operation signal is input (YES), the flow advances to step S5, and the control means 104 changes the room temperature Tr as in the data output section shown in FIG. The average data of the compressor 30 on / off time obtained by averaging the compressor 30 on / off time while performing normal operation for controlling the on / off of the compressor 30 for a predetermined time (data calculation interval). Calculate.
예를들어, 도 5에 도시된 데이터산출구간에서 소정시간동안 연속하는 복수개(예를들면, 4개)의 압축기(30) 온시간이 12분, 8분, 14분, 6분이라면 압축기(30) 온시간의 평균데이터는 10분이고, 도 5에 도시된 데이터산출구간에서 소정시간동안 연속하는 복수개(예를들면, 4개)의 압축기(30) 오프시간이 12분, 8분, 12분, 8분이라면, 압축기(30) 오프시간의 평균데이터는 10분이 되는 것이다.For example, if the on-time of the plurality of compressors 30 (for example, four) that is continuous for a predetermined time in the data output section shown in FIG. 5 is 12 minutes, 8 minutes, 14 minutes, and 6 minutes, the compressor 30 ) The average data of the on time is 10 minutes, the off time of the plurality of compressors 30 (for example, four) in succession for a predetermined time in the data output section shown in Figure 5 is 12 minutes, 8 minutes, 12 minutes, If it is 8 minutes, the average data of the compressor 30 off time will be 10 minutes.
이어서, 스텝S6에서 제어수단(104)은 운전시작후 소정시간(압축기 온/오프시간의 평균데이터를 산출하기 위한 데이터산출구간의 시간)이 경과하였는지를 판별하여, 소정시간이 경과하지 않은 경우(NO일 경우)에는 상기 스텝S5로 복귀하여 압축기(30) 온/오프시간의 평균데이터를 계속해서 산출하면서 스텝S5이하의 동작을 반복수행한다.Subsequently, in step S6, the control means 104 determines whether a predetermined time (time between data output sections for calculating average data of the compressor on / off time) has elapsed since the start of operation, and if the predetermined time has not elapsed (NO In this case, the flow returns to the step S5 to repeat the operation of the step S5 or less while continuously calculating the average data of the compressor 30 on / off time.
상기 스텝S6에서의 판별결과, 소정시간이 경과한 경우(YES일 경우)에는 스텝S7로 나아가서 제어수단(104)은 실내온도(Tr)와 설정온도(Ts)의 차에 따라 카오스연산을 실행하여 카오스 가중치(0~19;카오스 연산결과값)를 도 6에 도시된 도표에서와 같이, 결정한다.As a result of the discrimination in step S6, when a predetermined time has elapsed (YES), the control means 104 performs a chaotic operation according to the difference between the room temperature Tr and the set temperature Ts. The chaos weights (0 to 19; the result of the chaos calculation) are determined as in the diagram shown in FIG.
이어서, 스텝S8에서 제어수단(104)은 상기에서 산출된 압축기(30) 온/오프시간의 평균데이터를 백분율(%)화 한다음 이 백분율 값(절전운전율)을 5단계(예를들면, 90%, 80%, 70%, 60%, 50%)로 제어하여 절전운전시의 압축기(30) 온/오프시간을 다음과 같이 결정한다.Subsequently, in step S8, the control means 104 makes the average data of the on / off time of the compressor 30 calculated above as a percentage (%) and then sets this percentage value (power saving operation rate) in five steps (e.g., 90%, 80%, 70%, 60%, 50%) to determine the on / off time of the compressor 30 during power saving operation as follows.
즉, 산출된 압축기(30) 온시간의 평균데이터(10분)와 압축기(30) 오프시간의 평균데이터(10분)에 따라 압축기(30)를 온/오프시키는 것을 100% 운전이라고 했을 때, 90% 절전운전은 도 5에 도시된 데이터산출구간에서 산출된 압축기(30) 온시간의 평균데이터 10분에 절전운전율 90%을 곱하여 산출된 9분을 절전운전시의 압축기(30) 온시간으로 결정하고, 도 5에 도시된 데이터산출구간에서 산출된 압축기(30) 오프시간의 평균데이터 10분을 그대로 절전운전시의 압축기(30) 오프시간으로 결정하는 것이다.That is, when the compressor 30 is turned on / off according to the calculated average data of the on time of the compressor 30 (10 minutes) and the average data of the compressor 30 off time (10 minutes), 100% operation, In the 90% power saving operation, the average data of the compressor 30 on time calculated in the data output section shown in FIG. The average data 10 minutes of the compressor 30 off time calculated in the data output section shown in FIG. 5 is determined as the compressor 30 off time during power saving operation.
또한, 80% 절전운전은 도 5에 도시된 데이터산출구간에서 산출된 압축기(30) 온시간의 평균데이터 10분에 절전운전율 80%을 곱하여 산출된 8분을 절전운전시의 압축기(30) 온시간으로 결정하고, 도 5에 도시된 데이터산출구간에서 산출된 압축기(30) 오프시간의 평균데이터 10분을 그대로 절전운전시의 압축기(30) 오프시간으로 결정하는 것이다.In the 80% power saving operation, the compressor 30 at the time of power saving operation is calculated by multiplying the average data of the compressor 30 on time calculated in the data output section shown in FIG. The on time is determined, and the average data of 10 minutes of the compressor 30 off time calculated in the data output section shown in FIG. 5 is determined as the compressor 30 off time during power saving operation.
상기와 마찬가지로, 70% 절전운전은 압축기(30) 온시간(7분), 압축기(30) 오프시간(10분)으로 운전하고, 60% 절전운전은 압축기(30) 온시간(6분), 압축기(30) 오프시간(10분)으로 운전하며, 50% 절전운전은 압축기(30) 온시간(5분), 압축기(30) 오프시간(10분)으로 운전한다.As described above, 70% power saving operation is performed with the compressor 30 on time (7 minutes), compressor 30 off time (10 minutes), and 60% power saving operation with the compressor 30 on time (6 minutes), The compressor 30 is operated at an off time (10 minutes), and 50% power saving operation is performed at the compressor 30 on time (5 minutes) and the compressor 30 off time (10 minutes).
따라서, 상기 제어수단(104)에서는 실내온도(Tr)와 설정온도(Ts)의 차에 따라 결정된 카오스 가중치(0~19)에 따라 도 6에 도시된 도표에서와 같이, 압축기(30) 온시간의 평균데이터에 5단계(90%, 80%, 70%, 60%, 50%)의 절전운전율을 곱하여 결정된 압축기(30) 온시간, 압축기(30) 오프시간의 평균데이터로 압축기(30)를 구동하기위한 제어신호를 압축기구동수단(110)에 출력한다.Therefore, in the control means 104, as shown in the diagram shown in FIG. 6 according to the chaos weights (0 to 19) determined according to the difference between the room temperature (Tr) and the set temperature (Ts), the compressor 30 on time Compressor 30 is the average data of the compressor 30 on time and the compressor 30 off time determined by multiplying the average data of the power saving operation rate by 5 steps (90%, 80%, 70%, 60%, 50%). The control signal for driving the output to the compressor driving means (110).
이에 따라, 상기 압축기구동수단(110)에서는 제어수단(104)으로부터 출력되는 제어신호를 받아서 카오스 가중치(0~19)에 따라 5단계(90%, 80%, 70%, 60%, 50%)의 절전운전율로 결정된 압축기(30) 온/오프시간으로 압축기(30)를 주기적으로 온/오프시켜 도 5에 도시된 절전운전구간에서와 같이, 절전운전을 구현한다.Accordingly, the compressor driving means 110 receives the control signal output from the control means 104 and according to the chaos weight (0 ~ 19) 5 stages (90%, 80%, 70%, 60%, 50%) Compressor 30 is periodically turned on / off with the compressor 30 on / off time determined by the power saving operation ratio of to implement the power saving operation as shown in FIG. 5.
상기와 같은 절전운전시에, 스텝S9에서는 운전조작수단(102)의 절전운전키가 오프되어 운전조작수단(102)으로부터 제어수단(104)에 절전운전오프신호가 입력되었는지를 판별하여, 절전운전오프신호가 입력되지 않은 경우(NO일 경우)에는 상기 스텝S8로 복귀하여 스텝S8이하의 동작을 반복수행한다.In the above power saving operation, in step S9, the power saving operation key of the driving operation means 102 is turned off, and it is determined whether the power saving operation off signal is input from the operation operation means 102 to the control means 104, and the power saving operation is performed. If no OFF signal is input (NO), the flow returns to step S8 to repeat the operation of step S8 and below.
상기 스텝S9에서의 판별결과, 절전운전오프신호가 입력된 경우(YES일 경우)에는 스텝S10으로 나아가서 공기조화기는 절전운전 이전의 정상운전모드로 복귀하면서 동작을 종료한다.As a result of the discrimination in step S9, when the power saving operation off signal is input (YES), the flow goes to step S10, and the air conditioner returns to the normal operation mode before the power saving operation and ends the operation.
상기의 설명에서와 같이 본 발명에 의한 공기조화기의 절전운전 제어장치 및 그 방법에 의하면, 일정시간동안의 압축기 온/오프시간을 평균한 값을 백분율(%)화 한다음, 실내온도 및 설정온도의 차에 따라 카오스연산을 실행하여 결정된 카오스가중치에 따라 상기 압축기 온시간을 5단계의 절전운전율로 제어하여 압축기의 온시간을 단축하므로 운전소비전력을 감소시켜 절전효과를 높인다는 효과가 있다.According to the power saving operation control apparatus and method of the air conditioner according to the present invention as described above, the average value of the compressor on / off time for a predetermined time is converted into a percentage (%), and then the room temperature and setting. The compressor on time is controlled by the power saving operation rate of five stages according to the chaos weighting value determined by executing the chaos operation according to the difference of temperature, thereby shortening the on time of the compressor, thereby reducing the power consumption and increasing the power saving effect. .
