冷凍装置及び冷却システム
Document Type and Number:
Japanese Patent JP7277161
Kind Code:
B2
Abstract:
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
