REFRIGERATING DEVICE

A refrigeration apparatus excellent in workability, maintainability, and economy is provided. The refrigeration apparatus (100) includes: a usage-side expansion valve (31) whose opening degree is changed in response to a change in a flow rate or a pressure of a refrigerant on the upstream side; a first expansion valve (15); and a controller (50). The controller (50) exerts, in an oil recovery operation, an oil recovery first control on the first expansion valve (15) to attain a first opening degree (an opening degree of increasing an opening degree of the usage-side expansion valve (31) in relation to a reduction in the flow rate or the pressure of the refrigerant passing through the first expansion valve (15)), to reduce the flow rate or the pressure of the refrigerant passing through the first expansion valve (15). The controller (50) exerts an oil recovery second control following the oil recovery first control on the first expansion valve (15) to attain a second opening degree (an opening degree that allows a liquid refrigerant to flow into a usage-side heat exchanger (32) before the opening degree of the usage-side expansion valve (31) is reduced in relation to an increase in the flow rate or the pressure of the refrigerant passing through the first expansion valve (15)), to increase the flow rate or the pressure of the refrigerant passing through the first expansion valve (15).
