摘要： A first heat-source-side flow rate adjusting valve (26), an opening degree of which is adjustable, is connected to a liquid side of an upper-side first heat-source-side heat exchanger (24), and a second heat-source-side flow rate adjusting valve (27), an opening degree of which is adjustable, is connected to a liquid side of a lower-side second heat-source-side heat exchanger (25). In a defrost operation for defrosting the first and second heat-source-side heat exchangers (24, 25), the opening degrees of the first and second heat-source-side flow rate adjusting valves (26, 27) are controlled so as to achieve a defrost flow rate ratio, which is a flow rate ratio at which more refrigerant flows to the second heat-source-side heat exchanger (25) than during an air-cooling operation.

摘要： 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.

摘要： An electronic expansion valve includes a valve body, a valve seat, and a stepping motor. A valve portion is formed at a forward end of the valve body. The valve seat forms a variable throttle portion between the valve portion and the valve seat by allowing the valve body to move in an axial direction. The stepping motor moves the valve portion in accordance with a pulse number. At least one part of a side surface of the valve portion is shaped so that an opening degree ratio becomes constant.
