Abstract

본 발명은 난방 운전 중에 압축기의 토출 냉매 압력의 이상 고압 상태를 쾌적성을 손상시키지 않으면서 해소하는 것을 과제로 한다. 이를 위하여, 압력 센서(1)가 소정 압력 이상을 검출하여 냉매 제어 밸브(55)의 제어방식을 선택할 필요가 있을 때에는 운전 중인 전체 실내기의 냉매 제어 밸브(55)의 개도를 현재의 1/2로 조이고, 그 결과 압력이 저하된 경우에는 냉매 제어 밸브(55)의 개도를 폐쇄하는 방식의 제어를 선택하고 압력이 상승된 경우에는 냉매 제어 밸브(55)의 개도를 개방하는 방식의 제어를 선택한다. 선택된 밸브 제어 방식에 의해 냉매 제어 밸브(55)의 개도를 조정하여 이상 고압를 해소한다.This invention makes it a subject to solve the abnormal high pressure state of the discharge refrigerant | pressure pressure of a compressor during heating operation, without impairing comfort. To this end, when the pressure sensor 1 needs to detect a predetermined pressure or more and select the control method of the refrigerant control valve 55, the opening degree of the refrigerant control valve 55 of all indoor units in operation is changed to 1/2 of the present. When the pressure is reduced, the control is selected to close the opening degree of the refrigerant control valve 55. When the pressure is increased, the control is selected to open the opening degree of the refrigerant control valve 55. . The opening degree of the refrigerant control valve 55 is adjusted by the selected valve control method to solve the abnormal high pressure.
