PROBLEM TO BE SOLVED: To provide a refrigeration warehouse capable of attaining energy saving.SOLUTION: A refrigeration warehouse 100 comprises: a refrigerator 3; a plurality of unit coolers 4a to 4c connected to the refrigerator 3 and arranged in a warehouse main body 1; a plurality of solenoid valves 5a to 5c arranged between the refrigerator 3 and each of the plurality of unit coolers 4a to 4c; and a controller 7 for controlling ON/OFF of the plurality of solenoid valves 5a to 5c. The temperature set values for turning ON/OFF the plurality of solenoid valve 5a to 5c are set in such a way that they are different from each other for every plurality of unit coolers 4a to 4c. Thus, the controller 7 is constituted to control that the timings of ON/OFF of the plurality of solenoid valves 5a to 5c are made different to each other by turning ON/OFF the solenoid valves 5a to 5c on the basis of the temperature set value.SELECTED DRAWING: Figure 1 |
