상기와 같이 구성된 본 발명의 작용 및 효과를 도 4를 근거로 상세히 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described above in detail based on Figure 4 as follows.

본 발명은 필요에 따라 냉방기, 냉난방기, 항온항습기 등 필요한 장비들과 연동할 수 있도록 구성되어 있는 바, 그에 따른 각 접점의 구성은 별도로 추가됨은 당연하다. 본 발명에서는 냉방기만 연계된 상태이다.The present invention is configured to be interlocked with the necessary equipment such as air conditioners, air conditioners, constant temperature and humidity, if necessary, it is natural that the configuration of each contact is added separately. In the present invention, only the air conditioner is connected.

이와 같은 상태는 파워 공급에 따른 초기화를 진행한 후 먼저 설정부 및 모니터(310)의 입력버튼(312, 313, 314)들을 이용하여 실내온도를 설정하면(S10) MPU(321)는 각 단자대(324)에 접속된 실내온도/습도센서(330)와 실외온도센서(331)로부터 현재 실내의 온도, 습도를 입력받는다(S11, S12). 이러한 입력데이터를 이용하여 그 내부에 미리 설정한 조건에 따라 팬 온/오프, 타장비 즉 냉방기 절체운전을 실시한다.In this state, after initializing the power supply and setting the room temperature by using the input buttons 312, 313, and 314 of the setting unit and the monitor 310 (S10), the MPU 321 is connected to each terminal block ( The indoor temperature / humidity sensor 330 and the outdoor temperature sensor 331 connected to 324 receive the current indoor temperature and humidity (S11 and S12). Using these input data, fan on / off and other equipment, ie, cooler changeover operation, are executed according to preset conditions therein.

즉, 단계 S13에서 비교결과 실내 설정온도보다 외부 온도가 낮은 것으로 감지되고(S16), 실내 설정온도보다 실내 온도가 상승되는 것으로 판단되면(S20) MPU(321)는 SSR 모듈(322)을 제어하여 모터를 온시켜 실외의 공기를 실내로 유입시키는 팬동작을 실행한다(S20). 이러한 팬동작은 실내온도가 설정온도에 도달할 때까지 지속됨은 당연하다(S23).That is, when it is determined in step S13 that the external temperature is lower than the indoor set temperature (S16), and it is determined that the indoor temperature is increased than the indoor set temperature (S20), the MPU 321 controls the SSR module 322. By turning on the motor to perform a fan operation for introducing the outdoor air into the indoor (S20). Naturally, the fan operation is continued until the room temperature reaches the set temperature (S23).

한편, 냉방기 역시 SSR 모듈(322)의 단속에 따라 동작되는데, 이때 동작조건은 설정온도보다 실외온도가 높을 경우(S14), 우기철 습도 상한 경보이상일 경우(S15), 외기에 의한 필터오염으로 차압센서가 작동할 경우(S17)(S24), 혹한기로 실내설정온도보다 일정온도 낮을 경우(S18)(S25), 운전중 이상발생으로 정지하는 경우(S19)(S26)이다.On the other hand, the air conditioner is also operated according to the interruption of the SSR module 322, in which the operating conditions are when the outdoor temperature is higher than the set temperature (S14), when the upper season humidity above the upper limit alarm (S15), the differential pressure sensor due to filter contamination by the outside air In the case of operating (S17) (S24), a cold temperature is a certain temperature lower than the room set temperature (S18) (S25), the operation stops due to abnormal occurrence during operation (S19) (S26).

이상에서 살펴본 바와 같이 본 발명은 외기의 온도 중간기 및 동절기에 외부공기를 직접 실내로 유입시켜 실내온도를 조절함으로써 기존 사용하던 냉방기의 운전시간을 대폭 줄일 수 있음에 따른 냉방기 수명연장, 장비 유지보수비 절감, 에너지 절감 등 다양한 효과를 기대할 수 있고,As described above, in the present invention, the air temperature is extended and equipment maintenance cost is reduced by drastically reducing the operating time of the existing air conditioner by controlling the indoor temperature by directly introducing the outside air into the indoor and outdoor air temperatures during the middle and winter periods. , You can expect various effects such as energy saving,

특히, 기존에 설치된 냉방기, 냉·난방기, 항온항습기 등의 장비와 연동 사용할 수 있도록 함으로써 제품의 효율성을 일층 향상시킨 특징이 있다.In particular, it is possible to use in conjunction with the existing equipment such as air conditioners, air conditioners, constant temperature and humidity equipment, there is a feature that further improves the efficiency of the product.
