Abstract

The invention provides a refrigeration/air-conditioning apparatus (1) which can bypass an appropriate amount of liquid refrigerant to suppress a rise in discharge temperature, while suppressing, as much as possible, the opening/closing frequency of an electromagnetic valve (9), and in which it is possible to form a liquid bypass circuit (8) with a low-cost and simple structure. The refrigeration/air-conditioning apparatus (1), which is equipped with a liquid bypass circuit (8) provided with an electromagnetic valve (9), between a high-pressure liquid line (6B) in a refrigeration cycle (7) and a suction line (6C) running to a compressor (2), includes a control means (11) for opening and closing the electromagnetic valve (9) on the basis of a detected temperature in a discharge temperature sensor (10) provided in a discharge line (6A) from the compressor (2), and for varying a set temperature at which the electromagnetic valve (9) is closed depending on the time since the last time the electromagnetic valve was opened or closed.
