Provided is a refrigeration apparatus that secures safety while suppressing an increase in cost. A refrigeration apparatus performs a refrigeration cycle in a refrigerant circuit including a compressor, a heat source-side heat exchanger, and a usage-side heat exchanger. The refrigeration apparatus comprises a usage-side fan providing an air flow, and a controller. The usage-side fan is disposed in a target space where inside air is cooled. The controller performs a refrigerant leak determination process to determine whether a refrigerant leak occurs, based on a state of a refrigerant in the refrigerant circuit. When the controller performs the refrigerant leak determination process to determine that a refrigerant leak occurs, then the controller performs leakage refrigerant agitation control to operate the usage-side fan so as to suppress local emergence of a region where the refrigerant leaks at a high concentration in the target space.
