In a refrigeration apparatus, in a first operation mode, a comparison is made between a first liquid pipe temperature, which is a temperature of a refrigerant on a side of a liquid pipe heat exchanger that is near usage-side heat exchangers, and a second liquid pipe temperature, which is a temperature of the refrigerant on a side of the liquid pipe heat exchanger that is near a plurality of heat-source-side heat exchangers, the liquid pipe heat exchanger performing heat exchange with the refrigerant flowing through liquid sides of the heat-source-side heat exchangers. When an evaporation-switch liquid pipe temperature condition is satisfied, the heat-source-side heat exchanger functioning as a radiator of the refrigerant is switched to an evaporator of the refrigerant, and the first operation mode is switched to a second operation mode in which the plurality of heat-source-side heat exchangers are caused to function as evaporators of the refrigerant.
