AIR CONDITIONER AND OUTDOOR EQUIPMENT USED FOR IT

摘要

An air conditioner comprising a bypass path (14) for connecting the suction side of a compressor (1) to a liquid receiver (5) and a control valve (11) to close the bypass path (14) when a refrigerating cycle path is open and to open it when the refrigerating cycle path is closed, the compressor (1) being operated for a specified time after the bypass path (14) has been opened, whereby, because the compressor (1) is operated for a specified time after the bypass path (14) has been opened, refrigerant on the low pressure side can be moved irrespective of the state of refrigerant present on the low pressure side of the compressor (1) and then the compressor (1) can be started without causing liquid return to ensure the reliability of the compressor (1), and an accumulator to regulate the degree of dryness of refrigerant sucked into the compressor (1) can be removed so as to downsize the compressor and also reduce the amount of refrigerant used.
