The signal is input to the control means 104. (S12, S13)

즉, 운전조작수단(102)으로부터 운전시작신호가 입력되었는지를 판별하여, 운전신호가 입력되지 않은 경우에는 공기조화기를 운전대기상태로 유지하는 것이다.That is, it is determined whether the operation start signal is input from the operation operation means 102, and if the operation signal is not input, the air conditioner is kept in the operation standby state.

그리고, 운전조작수단(102)으로부터 운전시작신호가 입력된 상태에서 사용자가 운전조작수단(102)을 조작하여 운전 조건을 설정하기 위해 운전 선택 신호를 제어수단(104)으로 입력하여 공기조화기의 운전 조건을 설정한다.Then, when the operation start signal is input from the operation operation means 102, the user inputs an operation selection signal to the control means 104 to operate the operation operation means 102 to set the operation conditions of the air conditioner. Set the operating conditions.

이어서, 제어수단(104)은 상기 운전조작수단(102)으로부터 입력된 운전 조건이 제습운전인가를 판별하여, 제습운전이 아닌 경우에는 설정된 운전 조건에 따라 공기조화기를 운전한다.(S14, S15)Subsequently, the control means 104 determines whether the operation condition input from the operation operation means 102 is the dehumidification operation, and if the operation condition is not the dehumidification operation, operates the air conditioner according to the set operation condition. (S14, S15)

그리고, 상기 단계(S14)의 판별 결과, 제습운전인 경우에는 제어수단(104)이 실내온도감지수단(106)으로부터 입력된 실내온도가 사용자가 설정한 설정온도 즉, 사용자가 유지하고자 설정하는 공조공간의 온도 이상인가를 판단하여 실내온도가 설정온도 이상이면 냉방운전을 수행한다.(S16, S17)In the case of the dehumidification operation as a result of the determination in step S14, the control unit 104 controls the indoor temperature input from the indoor temperature detecting unit 106 to the set temperature set by the user, that is, the user sets to maintain it. If it is determined that the temperature of the space is higher than the room temperature, the cooling operation is performed. (S16, S17)

그리고, 상기 단계(S16)에서 실내온도가 설정온도미만이면 토출구를 폐쇄시킨다.(S18)If the indoor temperature is less than the preset temperature in step S16, the discharge port is closed.

즉, 토출구도어가 있는 경우에는 상기 제어수단(104)이 토출구 도어를 닫아 토출구를 폐쇄시키고, 토출구도어가 없는 경우에는 상기 제어수단(104)이 풍향조절수단(114)을 제어하여 상하풍향조절날개를 상향으로 회전시켜 토출구를 닫는다.That is, when there is a discharge port door, the control means 104 closes the discharge port door to close the discharge port, and when there is no discharge port door, the control means 104 controls the wind direction adjusting means 114 to control the up and down wind direction control wing. Rotate upward to close the discharge port.

이어서, 상기와 같이 토출구를 폐쇄시킨 다음에 상기 제어수단(104)은 실내팬모터구동수단(118)을 제어하여 실내팬모터(120)를 정지시킴과 동시에 압축기구동수단(110)을 제어하어 압축기(112)를 구동시킨다.(S19)Subsequently, after closing the discharge port as described above, the control means 104 controls the indoor fan motor driving means 118 to stop the indoor fan motor 120 and simultaneously controls the compressor driving means 110 to control the compressor. (112). (S19)

상기와 같이 실내팬모터(120)를 정지시킨 상태에서 압축기(112)를 구동시키면 미도시된 실내열교환기의 온도가 저하되기 시작하는데, 상기 실내열교환기의 온도가 일정온도(-1℃) 이하로 일정시간(6분)이 지날 때 까지 실내팬모터(120)를 정지시킨 상태에서 압축기(112)를 구동시킨다.(S20)When the compressor 112 is driven while the indoor fan motor 120 is stopped as described above, the temperature of the indoor heat exchanger (not shown) begins to decrease, and the temperature of the indoor heat exchanger is lower than a predetermined temperature (-1 ° C.). The compressor 112 is driven while the indoor fan motor 120 is stopped until a predetermined time (6 minutes) passes.

그리고, 상기와 같이 실내열교환기의 온도가 일정온도(-1℃) 이하로 일정시간(6분)이 지나면 상기 제어수단(104)은 실내팬모터구동수단(118)을 제어하여 실내팬모터(120)를 최저속도(600RPM)으로 회전시킴과 동시에 압축기구동수단(110)을 제어하여 압축기(112)를 정지시킨다.(S21)Then, as described above, if the temperature of the indoor heat exchanger passes a predetermined time (6 minutes) below a predetermined temperature (-1 ° C.), the control means 104 controls the indoor fan motor driving means 118 to control the indoor fan motor ( The compressor 112 is stopped by rotating the 120 at the minimum speed (600 RPM) and controlling the compressor driving means 110 (S21).

상기와 같이 압축기(112)를 정지시키면 실내열교환기의 온도가 상승하기 시작하는데, 상기 실내열교환기의 온도가 일정온도(4℃) 이상으로 상승하면 제습운전이 해제되었는가를 판단하여 제습운전이 해제되지 않았으면 상기 단계(S19)를 반복수행한다.(S22, S23)When the compressor 112 is stopped as described above, the temperature of the indoor heat exchanger starts to rise. When the temperature of the indoor heat exchanger rises above a predetermined temperature (4 ° C.), it is determined whether the dehumidification operation is released and the dehumidification operation is released. If not, the above step (S19) is repeated. (S22, S23)

이상에서 살펴본 바와 같이 본 발명에 따른 공기조화기의 제습운전 제어방법은, 공기조화기의 토출구를 폐쇄시킨 상태에서 압축기를 구동시켜 제습운전을 수행함에 따라 실내온도 변화를 최소화시키면서 제습량을 향상시키는 효과가 있다.As described above, the method for controlling the dehumidification operation of the air conditioner according to the present invention improves the amount of dehumidification while minimizing the change in room temperature by driving the compressor in a state in which the discharge port of the air conditioner is closed. It works.
