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 【課題】省エネルギー化を図ることが可能な冷蔵倉庫を提供する。【解決手段】この冷蔵倉庫１００は、冷凍機３と、冷凍機３に接続され、倉庫本体１内に配置される複数のユニットクーラ４ａ〜４ｃと、冷凍機３と複数のユニットクーラ４ａ〜４ｃの各々との間に設けられる複数の電磁弁５ａ〜５ｃと、複数の電磁弁５ａ〜５ｃのオンオフを制御するコントローラ７とを備え、電磁弁５ａ〜５ｃをオンオフする温度設定値は、複数のユニットクーラ４ａ〜４ｃ毎に互いに異なるように設定されており、コントローラ７は、温度設定値に基づいて電磁弁５ａ〜５ｃをオンオフすることにより、複数の電磁弁５ａ〜５ｃのオンオフのタイミングが異なるように制御するように構成されている。【選択図】図１
