본 발명은 가정용 소형 룸에어콘 및 대형 커스텀 냉난방기 등과 같이 실내온도와 설정온도의 차이에 따라 압축기의 주파수를 가변시키면서 구동시켜 실내를 냉방 및 난방하는 공조기기에 있어서, 실내공간의 크기에 따라 압축기의 주파수를 가변시켜 실내온도를 쾌적하게 조정하는 공조기기의 제어방법에 관한 것이다.The present invention relates to an air conditioner for cooling and heating a room by varying the frequency of a compressor according to a difference between an indoor temperature and a set temperature, such as a small room air conditioner and a large custom air conditioner for home use, and the frequency of the compressor according to the size of the indoor space. It relates to a control method of the air conditioning equipment to adjust the room temperature to change comfortably.
종래의 공조기기는 실내온도를 검출하고, 검출한 실내온도와 사용자가 임의로 설정한 설정온도의 차이에 따라 압축기의 주파수를 가변시키면서 구동시켜 냉방 및 난방열량을 조절하였으므로 실내공간의 크기에 관계없이 열량의 변화가 이루어지고, 실내공간의 크기가 작을 경우에는 압축기의 구종 및 정지횟수가 많아져 전력소비가 증가함은 물론 온도의 편차가 크게 발생하고, 실내공기의 온도를 항상 쾌적한 상태로 유지하기 못하게 되는등의 문제점이 있었다.The conventional air conditioner detects the indoor temperature and drives the compressor while varying the frequency of the compressor according to the difference between the detected indoor temperature and the set temperature set by the user. If the size of the room is small and the size of the indoor space is small, the number of compressors and the number of stops increases, increasing power consumption, causing a large temperature variation, and preventing the indoor air temperature from always being kept comfortable. There was a problem such as becoming.
따라서 본 발명의 목적은 냉방 및 난방할 실내공간의 크기를 검출하고, 검출한 실내공기의 크기에 따라 압축기의 주파수를 가변시키면서구동시킴으로써 실내온도와 설정온도의 편차를 줄이고, 압축기의 구동 및 정지횟수를 줄이는 운전제어방법을 제공하는데 있다.Accordingly, an object of the present invention is to detect the size of the indoor space to be cooled and heated, and to drive the drive while varying the frequency of the compressor in accordance with the size of the detected indoor air to reduce the deviation between the room temperature and the set temperature, the number of times of driving and stopping the compressor To provide an operation control method to reduce the.
본 발명의 다른 목적은 실내공간의 크기에 따라 압축기의 주파수에 비례하여 실내팬 및 실외팬의 구동속도를 가변시켜 실내의 온도를 항상 쾌적한 상태로 유지시키는 운전제어방법을 제공하는데 있다.Another object of the present invention is to provide an operation control method for maintaining the indoor temperature at all times by varying the driving speed of the indoor fan and the outdoor fan in proportion to the frequency of the compressor according to the size of the indoor space.
이와 같은 목적을 가지는 본 발명의 운전제어방법은 실내를 냉방 및 난방할 경우에 설정된 시간동안 압축기를 최대 냉방주파수 및 최대난방주파수를 구동시키고, 설정된 시간이 경과될 경우에 실내온도의 변화량을 검출하여 검출한 실내온도의 변화량으로 실내공간의 크기를 판단하며, 판단한 실내공간의 크기와, 실내온도 및 설정온도의 온도차에 대한 압축기의 주파수를 설정하여 구동을 제어한다.The operation control method of the present invention having the above object drives the maximum cooling frequency and the maximum heating frequency of the compressor for a set time when the room is cooled and heated, and detects the amount of change in the room temperature when the set time elapses. The size of the indoor space is determined by the amount of change in the detected indoor temperature, and the driving is controlled by setting the frequency of the compressor with respect to the determined size of the indoor space and the temperature difference between the indoor temperature and the set temperature.
이때, 실내공간의 크기가 클수록 압축기의 주파수를 높게 설정함은 물론 압축기의 주파수에 비례하여 실내팬 및 실외팬의 속도를 제어함으로써 실내온도와 설정온도의 편차를 줄이고, 압축기의 구동 및 정지회수를 줄이며, 실내온도를 항상 쾌적한 상태로 유지시키게 된다.At this time, the larger the size of the indoor space, the higher the frequency of the compressor as well as controlling the speed of the indoor fan and the outdoor fan in proportion to the frequency of the compressor to reduce the deviation between the indoor temperature and the set temperature, and the operation and stop frequency of the compressor Reduce and keep the room temperature comfortable all the time.

In the case of heating operation, the compressor 10 is driven at the maximum heating frequency in step 25, and then in step 26, it is determined whether the driving time Δt has elapsed by a predetermined time t. In this state, when the driving time Δt has elapsed by a predetermined time t, the temperature difference Δt between the initial indoor temperature and the current indoor temperature before the compressor 10 is driven in step 27 is set value. If it is determined to be greater than or equal to (X), if it is greater than or equal to the set value (X), it is determined that the indoor space is small in size, and as shown in (a) of FIG. 2 in step 28, the frequency of the compressor 10 is lowest. If the temperature difference DELTA T is less than or equal to the set value X, it is determined whether or not the set value Y is lower than or equal to the set value Y lower than the set value X in step 29. Above), it is determined that the size of the indoor space is medium, and in step 30, the frequency of the compressor 10 is set to a slightly higher frequency (F2) and driven, and the temperature difference (ΔT) is a set value (Y). If it is less than or equal to the size of the indoor space is determined to be very large, the frequency of the compressor 10 in step 31 Drive the number at a very high frequency (F3).
이와 같이 하여 압축기(10)의 주파수가 설정 및 구동되면, 단계(32)에서 압축기(10)의 주파수에 비례로 실내팬 및 실외팬을 구동시킨다.When the frequency of the compressor 10 is set and driven in this way, the indoor fan and the outdoor fan are driven in step 32 in proportion to the frequency of the compressor 10.
이와 같은 본 발명은 실내공간의 크기에 따라 압축기(10)의 주파수를 가변시키면서 구동하여 제3도의 (b)에 도시된 바와 같이 종래의 온도조절곡선(T1)에 비하여 본 발명의 온도조절곡선(T2)이 설정온도와 온도편차가 줄어들게 실내공기의 온도를 제어할 수 있다.The present invention is driven by varying the frequency of the compressor 10 according to the size of the indoor space as shown in (b) of Figure 3 compared to the conventional temperature control curve (T1) of the temperature control curve of the present invention ( T2) The temperature of the room air can be controlled to reduce the set temperature and the temperature deviation.
