Abstract (en)
In a refrigerating cycle (air conditioner) using mixture refrigerant, a mixing ratio of the refrigerant in a refrigerant circuit is measured by a mixing ratio detector (W1), and a controller (21) receives the detection signal to open a control valve (13) when the mixing ratio of a high boiling-point refrigerant component is low, whereby the high boiling-point refrigerant stocked in a liquid reservoir (14) is returned to the refrigerant circuit. The high boiling-point refrigerant which is supplied from the liquid reservoir (14) through the opening operation of the control valve (13) is supplied from a low pressure side of a compressor (1) into the refrigerant circuit to keep the mixing ratio of the refrigerant circulating in the refrigerant circuit to a predetermined value, thereby preventing abnormal increase of pressure of the refrigerant due to variation of the mixing ratio.
