이를 위해, 본 발명은 실외 및 실내 열교환기(1)(2)의 사이에 설치되어 냉방 및 제습 운전시 압축기(3)로부터 토출되는 냉매를 통과시키기 위해 선택적으로 개폐되는 사방밸브(4)와, 상기 실외 및 실내 열교환기(1)(2)에서 각각 열교환이 되어 토출되는 냉매를 감압시키는 제1,2모세관(5)(8)으로만 흐르도록 하기 위한 제1,2체크밸브(6),(9)와, 상기 실내 열교환기(2)에서 저온 냉매와 열교환을 하여 저온의 습기가 제거된 공기를 다시 유입 재열시켜 실내의 유입공기와 동일한 상태로 토출시키기 위한 재열 열교환기(7)로 구성된 공기 조화기의 정온제습 운전장치이다.To this end, the present invention is installed between the outdoor and indoor heat exchanger (1) (2) and the four-way valve (4) selectively opened and closed to pass through the refrigerant discharged from the compressor (3) during cooling and dehumidification operation, First and second check valves 6 for flowing only into the first and second capillary tubes 5 and 8 for reducing the refrigerant discharged by heat exchange in the outdoor and indoor heat exchangers 1 and 2, respectively, (9) and a reheat heat exchanger (7) for heat-exchanging with the low temperature refrigerant in the indoor heat exchanger (2) and reheating the air from which low-temperature moisture has been removed again to discharge the same in the same state as the inflow air in the room. Constant temperature dehumidification operation device of air conditioner.

또한, 본 발명은 실내측의 온도를 검출하는 온도 검출장치에 의해 일정온도를 기준으로 냉방 및 제습 운전여부를 판단하는 단계와, 상기 실내측의 온도가 일정온도 이상시 냉방운전을 실시한 후 제습 운전을 수행하고 일정온도 이하시에는 즉시 제습 운전을 실시하는 단계와, 상기 실내측의 온도가 일정온도에 도달 후 유로내의 냉매 압력을 일정하게 안정시키기 위해 제1타이머에 의해 일정시간 정지시키는 단계와, 상기 제습 운전신호에 의해 정온 제습유로를 갖추도록 사방밸브를 절환시킨 후 제2타이머에 의해 일정시간 강제 제습운전을 한 다음 강제 정지시키는 단계를 반복적으로 수행하여 실내의 온도 및 습도를 제어하도록 된 공기 조화기의 정온제습 운전제어 방법이다.In addition, the present invention is a step of determining whether the cooling and dehumidification operation based on a predetermined temperature by a temperature detection device for detecting the temperature of the indoor side, and the dehumidification operation after performing the cooling operation when the temperature of the indoor side is above a certain temperature Performing a dehumidifying operation immediately after the predetermined temperature is lower than the predetermined temperature, stopping the predetermined time by the first timer to stabilize the refrigerant pressure in the flow path after the indoor temperature reaches the predetermined temperature; By switching the four-way valve to have a constant temperature dehumidification flow path according to the dehumidification operation signal, the step of performing forced dehumidification operation for a predetermined time by the second timer and then forcibly stopping the air to control the temperature and humidity of the room It is the control method of the constant temperature dehumidification operation of the conditioner.
