To provide a tunnel freezer capable of suppressing frost from adhering to an upstream side heat exchanger to improve continuous cooling efficiency.SOLUTION: A cooling system comprises a casing 10 forming a cooling chamber 13, a transfer device 15 that transfers an object to be cooled 5 in the cooling chamber 13, and a refrigeration device 30 having a cooling heat exchanger 93 that exchanges heat between air in the cooling chamber 13 and a refrigerant. A plurality of refrigeration devices 30 are arranged along the transfer direction of the transfer device 15, and the plurality of refrigeration devices 30 divide the inside of the cooling chamber 13 into a plurality of cooling sections 13a, 13b, 13c, 13d, and the evaporation temperatures of the plurality of refrigeration devices 30 in each cooling section are set so that the temperatures decrease from the upstream side to the downstream side in the transfer direction.SELECTED DRAWING: Figure 1 【課題】上流側の熱交換器への霜付着を抑制し、連続冷却の効率向上ができるトンネルフリーザーを提供する。【解決手段】冷却システムは、冷却室１３を形成するケーシング１０と、冷却室１３内で冷却対象物５を搬送する搬送装置１５と、冷却室１３の空気を冷媒と熱交換させる冷却熱交換器９３を有する冷凍装置３０とを備えている。冷凍装置３０は、搬送装置１５の搬送方向に沿って複数配置し、複数の冷凍装置３０は、冷却室１３内を、複数の冷却区間１３ａ，１３ｂ，１３ｃ，１３ｄに区分けし、各冷却区間での複数の冷凍装置３０の蒸発温度は、搬送方向の上流側から下流側に向かって温度が低くなるように設定する。【選択図】図１
