PROBLEM TO BE SOLVED: To cool items with different storing target temperatures at the same time, and to approximately independently control respective storage rooms with only little influence of load fluctuation of one evaporator on the other evaporator. SOLUTION: In order to reduce influence of the evaporators to each other by arranging a plurality of evaporators in parallel and to make the evaporation temperatures of the respective evaporators appropriate for the respective room temperatures, separate expansion valves are fixed on inlets of the respective evaporators, and a refrigerant flow regulator is fixed, for reducing pressure, on outlet side of the other evaporator so as to make the evaporator pressure lowest when returning to the compressor.
