CONTAINER REFRIGERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent external air taken into a container from being discharged without being circulated therein in a container refrigeration device which adjusts an air composition in the container by executing: air intake to introduce the external air into the container; and exhaust to discharge air inside the container out of the same.SOLUTION: A container refrigeration device 10 comprises: a gas supply unit 30 which supplies nitrogen concentrated air; an intake air duct 47a which introduces external air into a primary space S21 at an air intake side of an internal fan 26; an exhaust duct 46a which introduces air in a secondary space S22 at an air outlet side of the internal fan 26 into an external space of a container 11; and a controlled atmosphere (CA) device 60 which adjusts an air composition in the container 11. An inlet of the exhaust duct 46a is positioned in a manner that allows a fan housing 27c to block distribution of air blown out from the internal fan 26.SELECTED DRAWING: Figure 2
