Description

에어컨의 취침운전 제어방법How to control bedtime operation of air conditioner

본 발명은 운전주파수를 가변할 수 있는 인버터 에어컨에 있어서, 취침운전 제어방법에 관한 것이다.The present invention relates to a sleep operation control method for an inverter air conditioner capable of varying an operating frequency.

인버터 에어컨은 교류전압을 정류하여 직류전압으로 변환한 후 다시 교류로 변환하여 냉방 부하조건에 따라 운전주파수를 변화시키는 것으로, 일예로 압축기에 적용할 경우 운전주파수를 제어하여 회전수를 가변함으로써 냉방 능력을 가변시킬 수 있으며, 아울러 저소비 전력의 절전냉방 운전이 가능하다.Inverter air conditioner rectifies AC voltage, converts it into DC voltage, and then converts it into AC again to change the operating frequency according to the cooling load condition. For example, when applied to a compressor, the cooling capacity is controlled by varying the number of rotations by controlling the operating frequency. In addition, it is possible to save power consumption cooling operation of low power consumption.

이와 같이 인버터 에어컨은 부하에 따라 운전주파수를 변화시킬 수 있기 때문에 실내온도를 단시간내에 상승시키거나(난방시), 실내온도를 단시간내에 하강시켜(냉방시) 설정온도대역까지 도달하는 시간을 단축시킬 수 있으며, 부하의 정지가 거의 없기 때문에 실온의 변화를 최소온도 대역에서 정밀하게 유지할 수 있고, 최저 운전주파수로 기동한 후 점차 고속으로 변속되기 때문에 기동전류가 운전전류 보다도 낮아 기동시 다른 전기제품에 미치는 영향이 없으며, 아울러 일반 공조기에 비해 전력 손실이 적다.In this way, the inverter air conditioner can change the operating frequency according to the load, so that the indoor temperature can be increased within a short time (when heating) or the indoor temperature can be lowered within a short time (when cooling) to shorten the time to reach the set temperature band. Since there is almost no load stop, it is possible to precisely maintain the change in room temperature at the minimum temperature band, and since the speed is gradually changed at high speed after starting at the lowest operating frequency, the starting current is lower than the operating current, so that it is not applied to other electrical products. There is no impact and less power loss than standard air conditioners.

이러한 인버터 에어컨에 있어서, 종래의 취침운전 제어방법은 도 3과 같이 자동운전에서 취침운전을 수행하면 냉방판별시는 취침시작 1시간후에 희망온도를 1℃상승하고 난방판별시는 1시간후에 희망온도 3℃하강, 다시 3시간후에 4℃로 하강시키는 제어를 취침시작후 1회만 수행하기 때문에 실내온도 변화에 따른 적절한 취침제어가 어려운 점이 있다.In such an inverter air conditioner, the conventional bedtime operation control method is to increase the desired temperature by 1 ° C. after 1 hour at the start of bedtime when the bedtime operation is performed in the automatic operation as shown in FIG. Because the control to lower the temperature to 3 ° C. and lower the temperature to 4 ° C. after 3 hours is performed only once after the start of bedtime, there is a difficulty in controlling proper sleep according to the change of the room temperature.

본 발명은 이러한 점을 감안하여 안출된 것으로, 특히 취침운전에 따른 싸이클을 설정하여 반복적으로 수행토록 함으로써 실내온도 상황에 따라 취침제어를 할 수 있도록 하는 인버터 에어컨 취침운전 제어방법을 제공하는데 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a method for controlling an inverter air conditioner bedtime operation, which enables sleep control according to a room temperature situation by setting a cycle according to the bedtime operation repeatedly. .

이러한 목적을 달성하기 위한 본 발명은 취침 설정시 이전모드와 현재모드가 동일하면 취침운전에 따른 온도제어를 계속 수행하고 다를 경우에는 새로 판별된 냉난방에 따라 취침운전을 다시 수행하는 등 매 4시간 마다 운전모드 냉난방 판별을 할 수 있도록 한다.In order to achieve the above object, the present invention continuously controls the temperature according to the bedtime operation when the previous mode and the current mode are the same when setting the bedtime, and if every other time, performs the bedtime operation again according to the newly determined cooling and heating. Operation Mode It is possible to distinguish between heating and cooling.

이러한 방법에 의하면 자동운전에서 취침 설정시 매 4시간마다 실내온도 상황에 맞는 취침제어를 수행함으로 보다 쾌적한 취침조건을 제공할 수 있다.According to this method, more comfortable sleeping conditions can be provided by performing bedtime control according to the room temperature situation every 4 hours when setting the bedtime in the automatic operation.

도 2는 본 발명에 따른 취침운전 제어방법을 보인 순서도로써, 본 발명은 취침운전 개시후 일정시간이 경과하면 실내온도 조건을 고려하여 다시 운전모드를 수행토록 하는 것으로, 사용자가 키입력부(14)를 통해 취침운전에 따른 냉방 또는 난방운전 모드를 설정하면 실내마이컴(13)에서는 이에 따른 운전모드(S1)를 판단하고 각종 부하를 제어하여 취침운전을 수행한다.FIG. 2 is a flowchart illustrating a method for controlling sleep operation according to the present invention. The present invention allows the user to perform the operation mode again in consideration of the indoor temperature condition after a predetermined time has elapsed after the start of the sleep operation. When the cooling or heating operation mode is set according to the sleep operation, the indoor microcomputer 13 performs the sleep operation by determining the operation mode S1 according to this and controlling various loads.

만약 사용자가 설정한 취침운전모드가 냉방모드로 판단될 경우 실내마이컴(13)에서는 취침모드에 따른 설정된 온도를 유지하면서 냉방운전을 수행하게 되며, 이후 1시간이 경과 하면 압축기(27)의 운전주파수 및 실내외팬모터(12)(22)의 회전수를 제어하여 희망온도를 1℃ 상승(S2-S3)시키게 된다.If it is determined that the sleep mode set by the user is the cooling mode, the indoor microcomputer 13 performs the cooling operation while maintaining the set temperature according to the sleep mode. After 1 hour, the operating frequency of the compressor 27 And controlling the rotation speed of the indoor / outdoor fan motors 12 and 22 to raise the desired temperature by 1 ° C. (S2-S3).

일예로 취침운전을 개시할 때 실내온도가 27℃를 유지하고 있으면 1시간 동안 동일한 실내온도를 유지하면서 냉방운전을 실행하게 되며, 이후 1시간이 경과 하면 희망온도를 1℃ 상승시킨 28℃로 냉방운전을 실행한다.For example, when starting the bedtime operation, if the room temperature is maintained at 27 ° C, the cooling operation is performed while maintaining the same room temperature for 1 hour. After 1 hour, the desired temperature is increased to 28 ° C by raising the desired temperature by 1 ° C. Carry out the operation.

이때 실내마이컴(13)은 희망온도로 상승시킬 경우 압축기(27)의 운전주파수를 약 30초 간격으로 2Hz씩 다운되게 실외마이컴(23)을 제어하여 급격한 온도변화가 발생하지 않도록 한다.At this time, the indoor microcomputer 13 controls the outdoor microcomputer 23 so that the operating frequency of the compressor 27 is lowered by 2 Hz at intervals of about 30 seconds when the temperature is raised to a desired temperature so that a sudden temperature change does not occur.

이와 같은 취침운전을 수행하면서 설정된 시간 4시간이 경과(S4)하면 실내마이컴(13)에서는 다시 운전모드를 판단하고 이전모드 즉 냉방모드와 동일하면 현재의 실내온도를 기준으로 상술한 취침운전을 수행한다.When the set time 4 hours have elapsed while performing such a sleep operation (S4), the indoor microcomputer 13 determines the operation mode again, and if the same as the previous mode, that is, the cooling mode, performs the aforementioned sleep operation based on the current indoor temperature. do.

반대로 단계1에 있어서, 사용자가 설정한 취침운전모드가 난방모드로 판단될 경우 실내마이컴(13)에서는 취침모드에 따른 설정된 온도를 유지하면서 난방운전을 수행하게 되며, 이후 1시간이 경과 하면 압축기(27)의 운전주파수 및 실내외팬모터(12)(22)의 회전수를 제어하여 희망온도를 3℃ 다운 (S5-S6)시키게 된다.On the contrary, in step 1, when it is determined that the sleep mode set by the user is the heating mode, the indoor microcomputer 13 performs the heating operation while maintaining the set temperature according to the sleep mode. After 1 hour, the compressor ( By controlling the operating frequency of the 27) and the number of rotations of the indoor and outdoor fan motors 12 and 22, the desired temperature is lowered by 3 ° C (S5-S6).

일예로 취침운전을 개시할 때 실내온도가 25℃를 유지하고 있으면 1시간 동안 동일한 실내온도를 유지하면서 냉방운전을 실행하게 되며, 이후 1시간이 경과 하면 압축기(27)의 운전주파수를 제어하여 희망온도를 3℃ 다운시킨 22℃로 난방운전을 실행한다.For example, when starting the bedtime operation, if the room temperature is maintained at 25 ° C, the cooling operation is performed while maintaining the same room temperature for 1 hour, and after 1 hour, the operating frequency of the compressor 27 is controlled and desired. The heating operation is performed at 22 ° C. with a temperature of 3 ° C.

이후 난방 취침운전을 수행하면서 취침운전 개시 3시간이 경과(S7)하면 희망온도를 취침운전 개시때의 온도 25℃에서 다시 1℃를 다운시켜 21℃로 유지(S8)하면서 난방 취침운전을 수행하고, 이와 같은 운전으로 4시간이 경과(S4)하면 실내마이컴(13)에서는 다시 운전모드를 판단하고 이전모드 즉 난방모드와 동일하면 현재의 실내온도를 기준으로 상술한 취침운전을 수행하는 루틴을 반복함으로써 보다 쾌적한 취침 조건을 제공할 수 있다.After 3 hours of starting the bedtime operation while performing the heating bedtime operation (S7), the heating temperature is performed while maintaining the desired temperature at 21 ° C (S8) by lowering 1 ° C again from the temperature of 25 ° C at the time of starting the bedtime operation (S8). When 4 hours have elapsed (S4) due to such operation, the indoor microcomputer 13 determines the operation mode again, and if the same as the previous mode, that is, the heating mode, repeats the routine of performing the above-described sleep operation based on the current indoor temperature. By this, more comfortable sleeping conditions can be provided.

이상에서 설명한 바와 같이 본 발명은 취침운전모드에 있어서, 냉방 또는 난방을 수행하면서 일정한 시간이 경과하면 실내온도 상황에 맞는 취침운전 제어를 재수행함으로써 실내온도 변화에 대응하는 운전을 지속적으로 수행할 수 있는 쾌적한 환경을 조성할 수 있다.As described above, in the sleep mode, the present invention can continuously perform the operation corresponding to the change of the room temperature by re-executing the sleep operation control suitable for the room temperature situation after a certain time while cooling or heating is performed. I can create a comfortable environment.
