置。 A circuit in which a compressor, a condenser, a pressure reducing device, and a refrigeration evaporator are connected via piping in sequence, and a circuit in which a pressure reducing device and a cabin cooling evaporator are connected in parallel with the pressure reducing device and the refrigeration evaporator through piping. In a refrigeration cycle of a refrigeration system with a cabin cooler, a first bypass path leads high-temperature refrigerant from a compressor to the refrigeration evaporator, and a refrigerant from the refrigeration evaporator is led to a circuit of a pressure reducing device and a cabin cooling evaporator. The second bypass path is operated so that during defrosting operation, refrigerant from the compressor is sequentially sent to the first bypass path, the refrigeration evaporator, the second bypass path, the pressure reduction device, and the cabin cooling evaporator. A refrigeration device with a cabin cooler, characterized in that it is equipped with a flow path switching valve.
