The present invention relates to a heating operation control method of an air conditioner which prevents malfunction of the conditioner.
종래 기술에 의한 창문형 공기조화기는 도 1에 도시된 바와 같이 냉매를 고온고압으로 압축시키도록 바닥판(1)의 일측에 배설되는 압축기(11)와, 상기 압축기(11)에서 토출된 고온고압의 기체냉매를 받아 열교환하여 상온고압의 액체냉매를 토출하는 상기 바닥판(1)의 후면에 설치되는 실외열교환기(15)와, 상기 실외열교환기(15)에서 토출된 상온고압의 액체냉매의 압력을 감압시키도록 상기 압축기(11) 일측에 배설되는 모세관(21)과, 상기 모세관(21)을 통과하면서 감압된 저온저압의 액체냉매가 흡입구(2)를 통해 흡입된 실내공기를 열교환시킨 다음 저온저압의 기체냉매로 토출하도록 바닥판(1)의 전면에 배설되어 있는 실내열교환기(23)와, 흡입구(2)를 통해 실내공기를 흡입하여 상기 실내열교환기(23)로 공급하고 이때 열교환된 공기를 토출구(5)를 통해 실내로 토출시키도록 상기 실내열교환기(23)의 일측에 배설되어 있는 실내팬(25)과, 실외공기흡입구(3)를 통해 외부공기를 흡입하여 상기 실외열교환기(15)에서 발생된 열을 배출구멍(4)을 통해 외부로 배출시키는 실외팬(17)과, 상기 실내팬(25)과 실외팬(17)이 회전될 수 있도록 동력을 제공하는 송풍팬모터(6)로 구성되어 있다.The window type air conditioner according to the prior art has a compressor 11 disposed on one side of the bottom plate 1 to compress the refrigerant at a high temperature and high pressure, as shown in FIG. 1, and the high temperature and high pressure discharged from the compressor 11. The pressure of the outdoor heat exchanger (15) installed at the rear of the bottom plate (1) which receives the gas refrigerant and heat-exchanges and discharges the liquid refrigerant of room temperature and high pressure, and the liquid refrigerant of room temperature and high pressure discharged from the outdoor heat exchanger (15). The capillary tube 21 disposed on one side of the compressor 11 to reduce the pressure and the low temperature low pressure liquid refrigerant depressurized while passing through the capillary tube 21 heat exchange the indoor air sucked through the inlet port 2, and then An indoor heat exchanger (23) disposed on the front of the bottom plate (1) so as to discharge to the low-pressure gas refrigerant, and sucks the indoor air through the suction port (2) to supply to the indoor heat exchanger (23) and heat exchanged Air is discharged through the discharge port 5 The indoor fan 25 disposed on one side of the indoor heat exchanger 23 and the outdoor air suction opening 3 are sucked into the outside air to discharge the heat generated by the outdoor heat exchanger 15. It consists of an outdoor fan (17) for discharging to the outside through the hole (4), and a blowing fan motor (6) for providing power to rotate the indoor fan 25 and the outdoor fan (17).
상기와 같이 구성된 냉난방을 겸하여 사용하는 창문형 히터 펌프 공기조화기의 냉난방 사이클은 도 2와 같이 도시할 수 있는데, 상기 도 2에 도시된 실선은 냉방 사이클이며, 점선은 난방 사이클을 나타낸다.The air-conditioning cycle of the window heater pump air conditioner used as the air-conditioning and configured as described above can be shown in Figure 2, the solid line shown in Figure 2 is a cooling cycle, the dotted line represents the heating cycle.
즉, 냉방운전시에는 압축기(11)에서 의해 고온고압의 기체로 압축된 냉매가 사방밸브(13)를 통해 실외열교환기(15)에 유입되면, 실외팬(17)에 의해 송풍되는 공기로 열교환하여 냉매를 냉각시켜 액화한다.That is, during the cooling operation, when the refrigerant compressed by the gas of the high temperature and high pressure by the compressor 11 flows into the outdoor heat exchanger 15 through the four-way valve 13, the heat exchanged by the air blown by the outdoor fan 17. To cool the liquid to liquefy it.
그리고, 상기 실외열교환기(15)에서 액화된 냉매는 바이패스통로(19)와 제1모세관(21)을 통해 저온저압의 액체냉매로 감압된다.In addition, the refrigerant liquefied in the outdoor heat exchanger (15) is depressurized to a low temperature low pressure liquid refrigerant through the bypass passage (19) and the first capillary tube (21).
이에 따라, 실내열교환기(23)에서는 상기 제1모세관(21)에서 감압된 저온저압의 냉매를 받아 실내팬(25)에 의해 송풍되는 공기를 냉매의 증발잠열에 의해 열교환하므로써 발생된 냉풍을 실내로 토출해서 냉방을 행하고, 상기 실내열교환기(23)에서 출력된 상온저압의 기체냉매는 다시 압축기(11)로 흡입되어 도 2의 실선과 같이 반복순환되는 냉방사이클을 수행한다.Accordingly, the indoor heat exchanger 23 receives the coolant of the low-temperature low-pressure refrigerant reduced in the first capillary tube 21 and heats the air blown by the indoor fan 25 by heat exchange by the latent heat of evaporation of the coolant. After cooling, cooling is performed, and the gas coolant of normal temperature and low pressure output from the indoor heat exchanger (23) is sucked into the compressor (11) again and performs a cooling cycle that is repeatedly circulated as shown by the solid line of FIG.
그리고, 난방운전시에는 압축기(11)에 의해 고온고압의 기체로 압축된 냉매가 사방밸브(13)를 통해 실내열교환기(23)에 유입되면, 실내팬(25)에 의해 송풍되는 공기를 열교환하여 상온고압의 냉매로 냉각시킴에 따라 생성된 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. By cooling with a refrigerant at room temperature and high pressure, the generated warm air is discharged into the room to perform heating.
그리고, 상기 실내열교환기(23)에서 액화된 냉매는 제1 및 제2모세관(21, 27)을 통해 저온저압의 냉매로 감압된다.In addition, 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).
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 2의 점선과 같이 반복순환되는 난방 싸이클을 형성한다.Accordingly, the outdoor heat exchanger 15 receives the low temperature low pressure refrigerant passing through the first and second capillaries 21 and 27 and heats the air blown by the outdoor fan 17 by heat of latent evaporation of the refrigerant to cool it. In addition, the low-temperature low-pressure gas refrigerant cooled in the outdoor heat exchanger 15 is again sucked into the compressor 11 to form a heating cycle that is repeatedly circulated as shown by the dotted line in FIG. 2.
상기와 같은 냉난방 겸용 창문형 히트 펌프 공기조화기의 난방운전은 도 3에 도시된 바와 같이, 미도시된 전원수단으로부터 출력되는 직류전압이 인가되면 제어수단(104)으로 인가되면 제어수단은 공기조화기를 초기화시킨다.(S1)As shown in FIG. 3, the heating operation of the combined air-conditioning window type heat pump air conditioner is applied to the control unit 104 when the DC voltage output from the power supply unit (not shown) is applied to the control unit. Initialize (S1)
이때, 사용자가 운전조작수단을 조작하여 운전시작신호를 제어수단으로 입력하고, 이어서 공기조화기의 운전 모드(예를 들면, 난방)와 설정온도, 설정풍량을 제어수단으로 입력한다.(S2, S3)At this time, the user operates the operation operation means to input the operation start signal to the control means, and then inputs the operation mode of the air conditioner (for example, heating), the set temperature, and the set air volume as the control means. S3)
이어서, 상기 제어수단은 상기 운전조작수단으로부터 입력된 운전 조건이 난방운전인가를 판별하여, 난방운전이 아닌 경우에는 설정된 운전 조건에 따라 공기조화기를 운전한다.(S4, S5)Subsequently, the control means determines whether the operation condition inputted from the driving operation means is a heating operation, and if it is not the heating operation, operates the air conditioner according to the set operating condition. (S4, S5)
그리고, 난방운전일 경우에 제어수단은 사방밸브를 소정의 지연시간(예를 들어, 1분 20초)만큼 지연시킨 다음 "온"시키고, 다시 소정시간(예를 들어, 10초)을 지연시키는데, 이는 압축기의 무리한 운전을 방지하기 위해 압축기 운전을 지연(1분 30초)시키기 위한 것이다.(S6, S7)In the heating operation, the control means delays the four-way valve by a predetermined delay time (for example, 1 minute and 20 seconds) and then "on", and again delays the predetermined time (for example, 10 seconds). This is to delay the compressor operation (1 minute and 30 seconds) in order to prevent excessive operation of the compressor. (S6, S7)
상기와 같이 소정시간(1분 30초) 지연시킨 다음, 이어서, 실내기 본체내로 흡입되는 실내공기의 온도를 감지한 실내온도와 운전조작수단을 조작하여 설정한 설정온도를 비교한다.(S8, S9)After delaying the predetermined time (1 minute 30 seconds) as described above, the indoor temperature detected by the temperature of the indoor air sucked into the main body of the indoor unit is compared with the set temperature set by operating the operation operation means. (S8, S9 )
상기와 같이 비교한 결과, 감지된 실내온도가 설정온도 이하이면 제어수단은 압축기 및 실외팬을 구동시키고, 실내온도가 설정온도 보다 크면 압축기 및 실외팬을 정지시킨다.(S10, S11)As a result of the comparison, the control means drives the compressor and the outdoor fan when the sensed indoor temperature is below the set temperature, and stops the compressor and the outdoor fan when the indoor temperature is greater than the set temperature (S10, S11).
이어서, 제어수단은 실내열교환기온도와 설정온도(난방초기시 냉풍토출을 방지하기 위한 배관온도)를 비교하여, 실내열교환기온도가 설정온도 보다 크면 설정풍량으로 실내팬을 구동시켜서 난방운전을 수행하고, 실내열교환기온도가 설정온도 이하이면 실내열교환기의 온도가 설정온도 보다 커질 때 까지 실내팬의 풍량을 냉풍방지풍량(예를 들어, 미풍)으로 제한한다.(S12, S13, S14, S15, S16)Subsequently, the control means compares the indoor heat exchanger temperature with the set temperature (piping temperature for preventing cold air discharge during the initial heating), and if the indoor heat exchanger temperature is higher than the set temperature, the indoor fan is operated with the set air volume to perform the heating operation. If the temperature of the indoor heat exchanger is lower than the set temperature, the air flow of the indoor fan is limited to the amount of cold wind prevention air (for example, a breeze) until the temperature of the indoor heat exchanger is greater than the set temperature. (S12, S13, S14, S15, S16)
이어서, 상기 제어수단은 사용자가 운전조작수단을 조작하여 운전정지신호를 입력할 때 까지 실내팬을 설정풍량으로 구동시키면서 난방운전을 수행한다.(S16, S17)Subsequently, the control means performs the heating operation while driving the indoor fan at the set air volume until the user operates the operation operation means to input the operation stop signal. (S16, S17)
그리고, 사용자가 운전조작수단을 조작하여 운전정지신호를 제어수단으로 입력하면 상기 제어수단은 현재 공기조화기의 운전상태를 저장한 다음 공기조화기의 운전을 정지시킨다.(S18, S19)Then, when the user operates the operation operation means to input the operation stop signal to the control means, the control means stores the operation state of the current air conditioner and then stops the operation of the air conditioner (S18, S19).
그러나, 상기와 같은 종래의 공기조화기의 난방운전 제어방법은, 난방운전중 냉풍방지운전시 실내팬이 동작하지 않아 공기조화기내의 공기순환이 되지 않으므로, 실내열교환기의 온도증가로 인하여 실내온도감지수단에서 감지하는 실내온도가 실제 실내온도에 비하여 높게 감지함에 따라 공기조화기의 오동작이 발생되는 문제점이 있었다.However, the heating operation control method of the conventional air conditioner as described above, because the indoor fan does not operate during the cold wind prevention operation during the heating operation, the air circulation in the air conditioner does not operate, the room temperature due to the increase of the temperature of the indoor heat exchanger There was a problem that a malfunction of the air conditioner occurs as the room temperature detected by the sensing means is detected higher than the actual room temperature.
즉, 난방운전시 냉풍방지동작이 시작되면, 실내열교환기의 온도가 특정 온도이하일 경우 실내팬이 강제로 오프되거나 풍량이 제한되는 냉풍방지운전을 수행하게 되는데, 이때 실내열교환기온도가 급격히 상승하고 실내팬이 동작하지 않음에 따라 실내온도감지수단이 실내온도를 실제 실내온도보다 높게 감지한다.That is, when the cold air prevention operation is started during the heating operation, if the temperature of the indoor heat exchanger is below a certain temperature, the indoor fan is forcibly turned off or cold wind prevention operation is performed in which the air volume is limited. As the indoor fan does not operate, the indoor temperature detecting means detects the indoor temperature higher than the actual indoor temperature.
따라서, 실내온도감지수단이 감지한 실내온도가 설정온도(희망온도)이상의 온도 보다 높아 냉풍방지 동작이 끝났을 때 압축기 및 실외팬이 동작하게 않게 되고, 상기와 같이 압축기 및 실외팬이 동작하지 않으면 다시 실내열교환기온도가 낮아져 다시 냉풍방지운전을 수행함에 따라 압축기와 사방밸브가 온/오프를 반복하는 오동작을 한다.Therefore, when the indoor temperature detected by the indoor temperature sensing means is higher than the set temperature (desired temperature) or higher, the compressor and the outdoor fan are not operated when the cold wind prevention operation is finished, and the compressor and the outdoor fan are not operated as described above. As the temperature of the indoor heat exchanger decreases and the cold wind prevention operation is performed again, the compressor and the four-way valve repeatedly operate on and off.
특히, 설정온도(희망온도)를 낮게 설정할 경우나 실내온도가 냉풍방지운전을 수행하게 하는 실내열교환기온도 보다 충분히 낮을 경우에는 상기와 같은 오동작이 발생하기 쉽다.In particular, when the set temperature (desired temperature) is set low or when the indoor temperature is sufficiently lower than the indoor heat exchanger temperature for performing cold wind prevention operation, the above malfunction is likely to occur.
따라서, 본 발명은 상기와 같은 종래의 제 문제점을 해소하기 위한 것으로, 난방운전시 냉풍방지 동작으로 인해 실내팬이 동작하지 않을 때 실내열교환기의 온도가 상승됨에 따라 실내온도를 정확하게 감지하지 못하게 되어 발생되는 공기조화기의 오동작을 방지하는 공기조화기의 난방운전 제어방법을 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above problems of the prior art, it is not possible to accurately detect the room temperature as the temperature of the indoor heat exchanger is increased when the indoor fan is not operated due to the cold wind prevention operation during heating operation. It is an object of the present invention to provide a heating operation control method of an air conditioner which prevents malfunction of the air conditioner.
이러한 목적을 달성하기 위한 본 발명에 따른 공기조화기의 난방운전 제어방법은, 실내공기를 열교환하여 온풍을 실내로 토출하는 공기조화기의 난방운전 제어방법에 있어서,In the heating operation control method of the air conditioner according to the present invention for achieving the above object, in the heating operation control method of the air conditioner to heat the indoor air to discharge the warm air to the room,
난방운전이 선택되면 사방밸브를 온시키는 단계와, 실내온도가 설정온도 이하이면 압축기 및 실외팬을 구동시키고, 실내온도가 설정온도 보다 크면 압축기 및 실외팬을 정지시키는 단계, 실내열교환기온도가 설정온도 보다 클 때 까지 초기에 측정된 실내온도에 따라 압축기 및 실외팬을 제어 구동시키고, 동시에 실내팬의 속도를 냉풍방지풍량으로 제한하는 냉풍방지운전단계, 운전정지신호가 입력될 때 까지 사용자가 설정한 풍량으로 실내팬을 구동시키고, 동시에 현재 실내온도에 따라 압축기 및 실외팬을 제어 구동시키는 난방운전단계 및, 운전정지신호가 입력되면 현재 공기조화기의 운전상태를 저장하고 공기조화기를 운전정지시키는 단계로 이루어진 것을 특징으로 한다.If the heating operation is selected, turning on the four-way valve, and if the indoor temperature is lower than the set temperature, driving the compressor and outdoor fan, if the indoor temperature is greater than the set temperature, stopping the compressor and outdoor fan, the indoor heat exchanger temperature is set Controls and operates the compressor and outdoor fan according to the initial measured indoor temperature until it is higher than the temperature, and at the same time, the user sets the cold wind prevention operation step to limit the speed of the indoor fan to the amount of cold wind preventing air and the operation stop signal is input. At the same time, the indoor fan is driven by the air volume, and at the same time, the heating operation step of controlling and driving the compressor and the outdoor fan according to the current indoor temperature, and when the operation stop signal is input, saves the current state of the air conditioner and stops the air conditioner. Characterized in consisting of steps.

상기와 같이 구성된 공기조화기의 운전제어장치에서의 본 발명에 따른 공기조화기의 난방운전 제어방법의 작용 및 효과를 상세히 설명하면 다음과 같다.The operation and effect of the heating operation control method of the air conditioner according to the present invention in the operation control device of the air conditioner configured as described above will be described in detail.
도 5은 본 발명에 따른 공기조화기의 난방운전 제어방법의 순서도로서, 도 5에서 S는 단계(step)을 표시한다.5 is a flowchart illustrating a heating operation control method of an air conditioner according to the present invention, in which S denotes a step.
먼저 공기조화기에 전원이 인가되면, 전원수단(100)은 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 공기조화기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(104)으로 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 supply terminal (not shown) into predetermined DC voltages required to drive the air conditioner, thereby driving each circuit and control means 104. )
상기와 같이 전원수단(100)으로부터 출력되는 직류전압이 인가되면 제어수단(104)으로 인가되면 제어수단(104)은 공기조화기를 초기화시킨다.(S21)When the DC voltage output from the power supply means 100 is applied as described above, the control means 104 initializes the air conditioner when the control means 104 is applied.
이때, 사용자가 운전조작수단(101)을 조작하여 운전시작신호를 제어수단(104)으로 입력하고, 공기조화기의 운전 모드(예를 들면, 난방)와 설정온도, 설정풍량을 입력한다.(S22, S23)At this time, the user operates the operation operation means 101 to input the operation start signal to the control means 104, and inputs the operation mode (for example, heating), the set temperature, and the set air volume of the air conditioner. S22, S23)
즉, 제어수단(104)은 운전조작수단(101)으로부터 운전시작신호가 입력되었는지를 판별하여, 운전신호가 입력되지 않은 경우에는 공기조화기를 운전대기상태로 유지하는 것이다.That is, the control means 104 determines whether the operation start signal is input from the operation operation means 101, and maintains the air conditioner in the operation standby state when the operation signal is not input.
이어서, 상기 제어수단(104)은 상기 운전조작수단(101)으로부터 입력된 운전 조건이 난방운전인가를 판별하여, 난방운전이 아닌 경우에는 설정된 운전 조건에 따라 공기조화기를 운전한다.(S24, S25)Subsequently, the control means 104 determines whether the operation condition input from the driving operation means 101 is a heating operation, and if it is not the heating operation, operates the air conditioner according to the set operating condition. (S24, S25) )
그리고, 상기 운전조작수단(101)으로부터 입력된 운전 조건이 난방운전일 경우에 제어수단(104)은 사방밸브구동수단(128)으로 사방밸브(140)를 "온"시키기 위한 제어신호를 출력하여 사방밸브(140)를 "온"시킨다.When the driving condition input from the driving operation means 101 is a heating operation, the control means 104 outputs a control signal for turning on the four way valve 140 to the four way valve driving means 128. Turn on the four-way valve 140.
이때, 상기 제어수단(104)은 사방밸브(140)를 소정의 지연시간(예를 들어, 1분 20초)만큼 지연시킨 다음 "온"시키도록 제어신호를 사방밸브구동수단(128)으로 출력하고, 다시 소정시간(예를 들어, 10초)을 지연시키는데, 이는 압축기(132)의 무리한 운전을 방지하기 위해 압축기 운전을 지연(1분 30초)시키기 위한 것이다.(S26, S27)At this time, the control means 104 delays the four-way valve 140 by a predetermined delay time (for example, 1 minute 20 seconds) and then outputs a control signal to the four-way valve driving means 128 to "on". Then, a predetermined time (for example, 10 seconds) is delayed again, which is to delay the compressor operation (1 minute and 30 seconds) to prevent excessive operation of the compressor 132. (S26, S27)
상기와 같이 소정시간(1분 30초) 지연시킨 다음, 이어서, 실내기 본체내로 흡입되는 실내공기의 온도를 실내온도감지수단(106)이 감지하여 제어수단(104)으로 출력하고, 상기 제어수단(104)은 사용자가 운전조작수단(101)을 조작하여 설정한 설정온도와 상기 실내온도감지수단(106)으로부터 입력된 실내온도를 비교한다.(S28, S29)After delaying the predetermined time (1 minute 30 seconds) as described above, the indoor temperature detecting means 106 detects the temperature of the indoor air sucked into the main body of the indoor unit and outputs it to the control means 104, wherein the control means ( 104 compares the set temperature set by the user operating the driving operation means 101 with the room temperature input from the room temperature detecting means 106. (S28, S29)
상기와 같이 비교한 결과, 감지된 실내온도가 설정온도 이하이면 제어수단(104)은 실내온도와 설정온도의 차에 따라 압축기(134)의 운전주파수 및 실외팬모터(136)의 회전수를 결정하여 압축기(134) 및 실외팬(136)을 구동시키도록 제어신호를 압축기구동수단(122) 및 실외팬모터구동수단(124)으로 출력하여 압축기(134) 및 실외팬(136)을 구동시키고, 실내온도가 설정온도 보다 크면 압축기(134) 및 실외팬(136)을 정지시키도록 제어신호를 압축기구동수단(122) 및 실외팬모터구동수단(124)으로 출력하여 압축기(134) 및 실외팬(136)을 정지시킨다.(S30, S31)As a result of the comparison, when the detected indoor temperature is less than or equal to the set temperature, the control unit 104 determines the operating frequency of the compressor 134 and the rotation speed of the outdoor fan motor 136 according to the difference between the indoor temperature and the set temperature. Outputting control signals to the compressor driving means 122 and the outdoor fan motor driving means 124 to drive the compressor 134 and the outdoor fan 136 to drive the compressor 134 and the outdoor fan 136. If the indoor temperature is greater than the set temperature, the control signal is output to the compressor driving means 122 and the outdoor fan motor driving means 124 to stop the compressor 134 and the outdoor fan 136. 136) is stopped (S30, S31).
이어서, 상기 압축기(134)의 구동에 의한 냉매순환에 의해 가열되는 실내열교환기의 온도를 실내열교환기온도감지수단(108)이 감지하여 제어수단(104)으로 출력하고, 상기 제어수단(104)은 상기 실내열교환기온도감지수단(108)에서 출력된 실내열교환기온도와 설정온도(난방초기시 냉풍토출을 방지하기 위한 배관온도)를 비교한다.(S32, S33)Subsequently, the indoor heat exchanger temperature sensing means 108 senses the temperature of the indoor heat exchanger heated by the refrigerant circulation driven by the compressor 134, and outputs the temperature to the control means 104. Compares the indoor heat exchanger temperature output from the indoor heat exchanger temperature sensing means 108 with a set temperature (piping temperature for preventing cold air discharge during the initial heating) (S32, S33).
상기와 같이 비교한 결과, 실내열교환기온도가 설정온도 보다 크면 제어수단(104)은 사용자가 운전조작수단(101)을 조작하여 설정한 풍량으로 실내팬(138)을 구동시키도록 제어신호를 실내팬모터구동수단(126)으로 출력하여, 실내팬(138)을 설정풍량으로 구동시킨다.(S38)As a result of the comparison, if the indoor heat exchanger temperature is greater than the set temperature, the control means 104 causes the indoor fan 138 to drive the indoor fan 138 with the air volume set by the user by operating the driving operation means 101. It outputs to the fan motor driving means 126 to drive the indoor fan 138 at the set air volume.
그리고, 실내열교환기온도가 설정온도 이하이면 제어수단(104)은 실내온도감지수단(106)에 의해 측정된 현재 실내온도를 저장하고, 저장된 실내온도에 따라 압축기(134) 및 실외팬(136)을 구동시키도록 제어신호를 압축기구동수단(122) 및 실외팬모터구동수단(124)으로 출력하여 압축기(134) 및 실외팬(136)을 구동시킨다.(S34, S35)If the indoor heat exchanger temperature is less than or equal to the set temperature, the control means 104 stores the current indoor temperature measured by the indoor temperature sensing means 106, and the compressor 134 and the outdoor fan 136 according to the stored indoor temperature. The control signal is output to the compressor driving means 122 and the outdoor fan motor driving means 124 to drive the compressor 134 and the outdoor fan 136. (S34, S35)
이어서, 제어수단(104)은 실내팬(138)의 풍량을 냉풍방지풍량(예를 들어, 미풍)으로 제한하도록 제어신호를 실내팬모터구동수단(126)으로 출력하여, 냉풍방지운전을 수행한다.(S36)Subsequently, the control means 104 outputs a control signal to the indoor fan motor driving means 126 so as to limit the air volume of the indoor fan 138 to a cold wind prevention wind amount (for example, a breeze), thereby performing cold wind prevention operation. (S36)
그리고, 제어수단(104)은 실내열교환기온도가 설정온도보다 큰가를 판단하여 크면 사용자가 운전조작수단(101)을 조작하여 설정한 설정풍량으로 실내팬(138)을 구동시키도록 제어신호를 실내팬모터구동수단(128)으로 출력하여 실내팬(138)를 설정풍량으로 구동시키고, 실내열교환기온도가 설정온도 이하이면 상기 단계(S36)를 반복 수행하여 냉풍방지운전을 계속한다.(S37, S38)Then, the control means 104 determines whether the indoor heat exchanger temperature is greater than the set temperature, and if it is large, the control signal 104 controls the indoor fan 138 to drive the indoor fan 138 at the set air volume set by the user operating the operation operation means 101. Output to the fan motor drive means 128 to drive the indoor fan 138 at the set air volume, and if the indoor heat exchanger temperature is less than the set temperature, repeat the step (S36) to continue the cold air prevention operation. (S37, S38)
이어서, 제어수단(104)은 사용자가 운전조작수단(101)을 조작하여 운전정지신호를 입력할 때 까지 실내온도감지수단(106)으로부터 입력된 현재 실내온도에 따라 압축기(134) 및 실외팬(136)을 제어 구동시키면서 난방운전을 수행한다.(S39, S40)Subsequently, the control means 104 controls the compressor 134 and the outdoor fan according to the current indoor temperature input from the indoor temperature sensing means 106 until the user operates the driving operation means 101 to input a driving stop signal. The heating operation is performed while the control unit 136 is controlled. (S39, S40).
그리고, 사용자가 운전조작수단(101)을 조작하여 운전정지신호를 제어수단(104)으로 입력하면 상기 제어수단(104)은 현재 공기조화기의 운전상태를 저장한 다음 공기조화기의 운전을 정지시킨다.(S41, S42)When the user operates the driving operation means 101 and inputs an operation stop signal to the control means 104, the control means 104 stores the operation state of the current air conditioner and then stops the operation of the air conditioner. (S41, S42)
이상에서 살펴본 바와 같이 본 발명에 따르면, 난방운전시 냉풍방지 동작으로 인해 실내팬이 동작하지 않을 때 실내열교환기의 온도가 상승됨에 따라 실내온도를 정확하게 감지하지 못하게 되어 발생되는 공기조화기의 오동작을 방지하는 효과가 있다.As described above, according to the present invention, when the indoor fan is not operated due to the operation of preventing the cold wind during heating operation, the malfunction of the air conditioner generated by the temperature of the indoor heat exchanger is not accurately sensed due to the increase in the temperature of the indoor heat exchanger. It is effective to prevent.
