Abstract
Description
Claims (4)
- 냉매를 순방향 또는 역방향으로 순환시켜서 냉·난방운전을 수행하는 냉·난방겸용 공기조학기에 있어서, 어큐뮬레이터에 부착되어 있는 써미스터에 의해 감지된 현재의 외기온도를 검출해서 마이크로컴퓨더에입력하여 마이크로컴퓨터에서 현재의 외기온도가 한냉온도일 경우 마이크로컴퓨터의 제어에 의해 한랭밸브를 오프시켜 액체냉매의 일정량을 잔류시키도록 상기 어큐뮬레이터전만에 보조어큐뮬레이터가 배설되어 있는 것을 특징으로 하는 공기조화기의 압축기 보호장치.
- 마이크로컴퓨터를 초기화한 상태에서 난방 운전인지의 여부를 판별하고, 난방운전일 경우에는 써이스더에 의해 외기온도를 감지한 후, 이 외기온도를 마이크로컴퓨터에서 받아 현재의 외기온도가 한랭온도인지의 여부를 판별하여 한랭밸브를 온 또는 오프하여 액체상태의 냉매를 직접 어큐뮬레이터로 유입하거나 또는브조어큐뮬레이터를 거치도록 하여 항상 최척상태의 난방운전이 수행되도록 하고, 냉방 또는 제습운전일 경우에는 한랭밸브를 온하여 냉매가 보조어큐뮬레이터를 거치지않고 직접 어큐뮬레이터에 유입원 후 압축기에공급되어서 냉방운전 또는 제습운전이 수행되도록 하는 것을 특징으로 하는 공기조화기의 압축기 보호방법
- 제2항에 있어서, 상기 현재의 외기온도가 한랭온도이면 냉매를 직접 어큐뮬레이터를 거쳐서 압축기에유입되드록 한랭밸브가 온되는 것을 특징으로 하는 공기조화기의 압축기 보호방법.
- 제2항에 있어서, 상기 현재의 외기온도가 한랭온도가 아니면 냉매를 일반 보조어큐뮬레이터를 거치도록 하여 일부 냉매량이 보조어큐뮬레이터에 저장되고 나머지 냉매량만이 어큐뮬레이터를 거쳐서 압축기에유입되도록 한랭밸브를 오프하는 것을 특깅으로 하는 공기조학기의 압축기 보호방법.
