본 발명은 공기조화기의 운전시에 변화하는 실내측 열교환량에 따라 압축기의 운전주파수를 변환하여 상기 공기조화기를 최적으로 운전제어하는 공기조화기의 운전제어장치 및 그 제어방법에 관한 것이다.The present invention relates to an air conditioner operation control apparatus and a method for controlling the air conditioner, by converting an operation frequency of a compressor according to an indoor heat exchange amount that is changed during operation of an air conditioner.

일반적으로, 종래에 의한 공기조화기에 있어서는 실내온도감지수단에 의해 실내의 온도를 감지하고, 그 감지된 실내온도데이타를 제어수단에서 입력받아 사용자에 의해 설정된 설정온도데이타와 비교한 다음, 그 온도차에 따라 압축기의 운전주파수를 변환시켜 압축기를 구동하였다.In general, in the conventional air conditioner, the indoor temperature is sensed by the indoor temperature sensing means, the detected indoor temperature data is inputted from the control means, and compared with the set temperature data set by the user. Accordingly, the compressor was driven by converting the operating frequency of the compressor.

즉, 상기 실내온도감지수단에 의해 감지된 실내온도와 설정온도의 차가 큰 경우에는 공기조화기의 운전초기에 상기 제어수단의 제어에 의해 압축기의 운전주파수를 높여 압축능력을 증대시키고, 상기 온도차가 작은 경우에는 상기 제어수단의 제어에 의해 압축기의 운전주파수를 낮추어 실내온도를 사용자가 설정한 온도로 제어하는 방식을 사용하고 있었다.That is, when the difference between the indoor temperature and the set temperature detected by the indoor temperature sensing means is large, the operation frequency of the compressor is increased by the control of the control means at the beginning of operation of the air conditioner to increase the compression capacity, and the temperature difference is In a small case, a method of controlling the room temperature to a temperature set by a user by lowering an operating frequency of the compressor by the control of the control means was used.

그런데, 이와같은 방식에 있어서는 실내측 열교환량 즉, 실내토출풍량의 변화와는 무관하게 단지 실내온도와 설정온도의 차, 또는 실외온도에 따라 압축기의 운전주파수를 변환시킴으로써 난방시의 실내토출풍량저단에서는 압축기의 토출압력이 증가하여 과부하상태가 되므로 난방효율이 감소되고, 실내토출풍량고단에서는 압축기의 토출압력과 응축압력이 감소하여 실내기에 토출되는 공기온도가 저하되어 쾌적한 실내공기조화를 유지할 수 없다는 문제점이 있었다.However, in such a method, regardless of the change in the indoor heat exchange rate, that is, the indoor discharge air volume, the indoor discharge air volume during heating is changed by simply changing the operating frequency of the compressor according to the difference between the indoor temperature and the set temperature or the outdoor temperature. In this case, the discharge pressure of the compressor is increased to overload the heating efficiency, and at the indoor discharge air flow stage, the discharge pressure and the condensation pressure of the compressor are decreased, so that the air temperature discharged to the indoor unit is lowered, so that it is not possible to maintain comfortable indoor air conditioning. There was a problem.

또한, 냉방시의 실내토출풍량저단에서는 증발압력의 저하로 인하여 실내기에 토출되는 공기온도가 저하되어 냉방병의 원인이 되었고, 실내토출풍량고단에서는 증발압력의 상승에 따라 실내기에 토출되는 공기온도가 상승하여 쾌적한 실내 공기조화를 유지할 수 없다는 문제점이 있었다.In addition, the air temperature discharged to the indoor unit is lowered at the lower stage of the indoor discharge air volume during cooling, causing the cooling bottle, and the air temperature discharged to the indoor unit increases as the evaporation pressure increases at the indoor discharge air volume stage. There was a problem that can not maintain a comfortable indoor air conditioning.

따라서, 본 발명은 상기와 같은 문제점을 해결하기위해 이루어진 것으로써, 본 발명의 목적은 운전선택수단에 의해 선택된 실내토출풍량에 따라 압축기의 운전주파수와 실외팬의 회전수를 변화시켜 난방시에는 고온의 풍량을, 냉방시에는 저온의 강한 풍량을 운전초기에 안정된 싸이클로 공급할 수 있기 때문에 단시간내에 쾌적한 실내 공기조화를 이룰 수 있을 뿐만 아니라, 상기 압축기의 불필요한 동작을 제거하여 소비전력을 절감할 수 있으면서도 기기의 성능 및 안전성을 보장할 수 있는 공기조화기의 운전제어장치 및 그 제어방법을 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to change the operating frequency of the compressor and the number of rotation of the outdoor fan in accordance with the amount of indoor discharge air selected by the operation selection means to heat the high temperature The air volume of air can be supplied to a stable cycle at the beginning of operation at the time of cooling, so that not only can the air conditioning be comfortable within a short time, but also the power consumption can be reduced by eliminating unnecessary operation of the compressor. It is to provide an operation control device and an control method of the air conditioner that can ensure the performance and safety of the.

A frequency converting means for receiving a control signal from the control means and converting an operating frequency of the compressor according to the air volume, and a compressor for receiving a control signal from the control means according to the operating frequency converted by the frequency converting means to drive the compressor. And an outdoor fan motor driving means for driving the outdoor fan motor by receiving a control signal from the control means in accordance with the driving means and the indoor discharge air volume selected by the operation selecting means.

또한, 본 발명에 의한 공기조화기의 운전제어방법은 운전선택수단에 의해 선택된 설정온도데이타 및 실내온도감지수단에 의해 감지된 실내온도데이타를 비교하여 그 온도차에 따라 압축기의 운전주파수를 결정하는 운전주파수결정스텝과, 상기 운전선택수단에 의해 선택된 실내토출풍량에 따라 상기 운전주파수결정스텝에서 결정된 압축기의 운전주파수 및 실외팬의 회전수를 변환하여 공조운전을 수행하는 운전스텝으로 이루어진 것을 특징으로 한다.In addition, the operation control method of the air conditioner according to the present invention compares the set temperature data selected by the operation selecting means and the indoor temperature data sensed by the indoor temperature sensing means to determine the operation frequency of the compressor according to the temperature difference. And an operation step of converting the operation frequency of the compressor determined in the operation frequency determination step and the rotation speed of the outdoor fan according to the frequency determination step and the indoor discharge air amount selected by the operation selection means to perform the air conditioning operation. .

이하, 본 발명의 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시한 바와같이, 공기조화기의 난방시에는 압축기(61)에 의해 고온고압의 기체로 압축된 냉매가 4방밸브(62)를 통해 실내열교환기(82)에 유입되면, 실내팬(81a)에 의해 송풍되는 공기를 상온의 냉각수 또는 공기에 의해 열교환하여 상온고압의 냉매로 냉각시킴에 따라 생성된 난풍을 실내로 토출해서 난방을 행한다.As shown in FIG. 1, when the air conditioner is heated, when the refrigerant compressed by the compressor 61 to the gas of high temperature and high pressure flows into the indoor heat exchanger 82 through the four-way valve 62, The air blown by the fan 81a is heat-exchanged with cooling water or air at room temperature and cooled with a refrigerant at room temperature and high pressure to discharge the generated warm air into the room for heating.

그리고, 상기 실내열교환기(82)에서 역화된 냉매는 모세관(63)을 통해 저온저압의 냉매로 감압된다.In addition, the refrigerant backfired in the indoor heat exchanger 82 is decompressed to the low temperature low pressure refrigerant through the capillary tube 63.

이에 따라, 실외열교환기(72)에서는 상기 모세관(63)에서 감압된 저온저압의 냉매를 받아서 실외팬(71a)에 의해 송풍되는 공기를 냉매의 증발잠열에 의해 열교환하여 냉각하고, 상기 실외열교환기(72)에서 냉각된 저온저압의 기체 냉매는 다시 압축기(61)로 흡입되어 제2도의 점선(…)과 같이 반복순환되는 난방싸이클을 형성한다.Accordingly, the outdoor heat exchanger (72) receives the refrigerant of low temperature and low pressure reduced by the capillary tube (63), heats and cools the air blown by the outdoor fan (71a) by heat of latent evaporation of the refrigerant, and cools the outdoor heat exchanger. The low-temperature, low-pressure gaseous refrigerant cooled at 72 is again sucked into the compressor 61 to form a heating cycle that is repeatedly circulated like a dotted line (...) in FIG.

한편, 공기조화기의 냉방시에는 압축기(61)에 의해 고온고압의 기체로 압축된 냉매가 4방밸브(62)를 통해 실외열교환기(72)에 유입되면, 실외팬(71a)에 의해 송풍되는 공기로 열교환하여 냉매를 냉각시켜 액화한다.On the other hand, during cooling of the air conditioner, if the refrigerant compressed by the gas of high temperature and high pressure by the compressor 61 flows into the outdoor heat exchanger 72 through the four-way valve 62, it is blown by the outdoor fan 71a. Heat exchange with air to cool the refrigerant to liquefy.

그리고, 상기 실외열교환기(72)에서 액화된 냉매는 모세관(63)을 통해 저온저압의 액체냉매로 감압된다.In addition, the refrigerant liquefied in the outdoor heat exchanger (72) is depressurized to a low temperature low pressure liquid refrigerant through the capillary tube (63).

이에 따라, 실내열교환기(82)에서는 상기 모세관(63)에서 감압된 저온저압의 냉매를 받아 실내팬(81a)에 의해 송풍되는 공기를 냉매의 증발잠열에 의해 열교환하므로써 발생된 냉풍을 실내로 토출해서 냉방을 행하고, 상기 실내열교환기(82)에서 냉각된 저압의 기체냉매는 다시 압축기(61)로 흡입되어 제2도의 실선(→)과 같이 반복순환되는 냉방싸이클을 형성한다.Accordingly, the indoor heat exchanger 82 discharges the cold air generated by the heat exchanged by the evaporative latent heat of the refrigerant blown by the indoor fan 81a by receiving the low-temperature low-pressure refrigerant depressurized by the capillary tube 63 to the room. Air is cooled, and the low-pressure gas refrigerant cooled in the indoor heat exchanger 82 is again sucked into the compressor 61 to form a cooling cycle that is repeatedly circulated like a solid line (→) in FIG.
