COOLING SYSTEM

To prevent driving of a compressor from being stopped due to high pressure abnormality.SOLUTION: A cooling system 1 includes: a refrigerator 11 having a compressor 31 for compressing a sucked refrigerant and a condenser 32 for condensing the refrigerant compressed by the compressor 31; and a plurality of showcases 12A, etc., which have expansion mechanisms 33A, etc., for adiabatically expanding part of the refrigerant condensed by the condenser 32 and evaporators 34A, etc., for evaporating the refrigerant adiabatically expanded by the expansion mechanisms 33A, etc., and sucking the refrigerant to the compressor 31. The cooling system cools a predetermined cooling region through the evaporation of the refrigerant by evaporators 34A, etc., of the plurality of showcases 12A, etc. The cooling system also includes a controller control section 42 that stops driving of the compressor 31 when a ratio of a low load showcase satisfying a preset low load condition relative to the plurality of the showcases 12A, etc., becomes a predetermined driving stop threshold value or larger.SELECTED DRAWING: Figure 1 【課題】圧縮機が高圧異常で駆動停止してしまうことを防止すること。【解決手段】吸引した冷媒を圧縮する圧縮機３１及び圧縮機３１で圧縮された冷媒を凝縮させる凝縮器３２を有した冷凍機１１と、凝縮器３２で凝縮した冷媒の一部を断熱膨張させる膨張機構３３Ａ等及び膨張機構３３Ａ等で断熱膨張した冷媒を蒸発させて圧縮機３１に吸引させる蒸発器３４Ａ等を有した複数のショーケース１２Ａ等とを備え、複数のショーケース１２Ａ等にて蒸発器３４Ａ等での冷媒の蒸発により所定の冷却領域を冷却する冷却システム１であって、複数のショーケース１２Ａ等に対する予め設定された低負荷条件を満足する低負荷ショーケースの割合が予め決められた駆動停止閾値以上となる場合に、圧縮機３１を駆動停止にさせるコントローラ制御部４２を備えている。【選択図】図１
