Title:
INDOOR AIR-CONDITIONING DEVICE AND CONTAINER REFRIGERATION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/179669
Kind Code:
A1
Abstract:
A CA device (60) equipped with a gas supply device (30) that performs a gas supply operation in which nitrogen-enriched air is supplied to the interior of a container (11), and a control unit that controls the gas supply operation such that the composition of the interior air reaches a desired composition. The control unit is configured so as to execute a carbon dioxide priority control wherein the gas supply operation is performed when the oxygen concentration of the interior air is equal to or greater than a prescribed upper limit concentration that is higher than a target oxygen concentration, the gas supply operation is stopped when the carbon dioxide concentration of the interior air has been lowered to a limit concentration that is lower than a target carbon dioxide concentration, and the gas supply operation is restarted when the carbon dioxide concentration of the interior air reaches a restart concentration that is higher than the target carbon dioxide concentration, due to the respiration of the produce (15).
