The present invention provides a refrigeration apparatus whereby a bias in the amount of excess refrigerant in high-pressure receivers can be suppressed even when a plurality of heat-source units having high-pressure receivers are connected. A first heat-source unit (2a) and a second heat-source unit (2b) each have a compressor (21 a, 21 b), heat-source-side heat exchangers (24a, 25a, 24b, 25b), a receiver (80a, 80b), a receiver liquid level detecting tube (43a, 43b) for detecting a state of near flooding, a receiver venting tube (41 a, 41 b), and an motor-operated valve (42a, 42b) provided to the receiver venting tube (41 a, 41 b). Heat-source-side controllers (20a, 20b) perform opening degree control so that the opening degree of the motor-operated valve corresponding to the receiver (80a, 80b) other than a receiver for which a nearly flooded state is detected is greater than the opening degree of the motor-operated valve corresponding to the receiver (80a, 80b) for which a nearly flooded state is detected. |
