An object of the present invention is to sufficiently reduce pressure pulsation in a refrigeration apparatus that employs carbon dioxide or the like as a refrigerant. A refrigeration apparatus according to the present invention includes a compression mechanism 11, radiators 13, 31, expansion mechanisms 15, 17, evaporators 13, 31, and a π-type silencer 20. The π-type silencer has a first silence space 201, a second silence space 202, and a first communication path 203. The first communication path connects the first silencing space and the second silencing space. The π-type silencer is incorporated in at least one of the space between the refrigerant discharge side of the compression mechanism and the inlet side of the radiator, and between the outlet side of the evaporator and the refrigerant suction side of the compression mechanism.
