Document Type and Number:
WIPO Patent Application WO/2020/009183
Kind Code:
A1
Abstract:
An in-compartment environment control system (10) provided in a transportation container (1) is provided with a refrigeration device (20), an air composition regulating device (40), a control device, and a state indicator sensor (15). An in-compartment temperature regulating unit of the control device controls the refrigeration device (20) in such a way that the temperature of the air inside the compartment adopts a set temperature. An air composition regulating device of the control device controls the air composition regulating device (40) in such a way that the oxygen concentration and the carbon dioxide concentration of the air in the compartment adopt respective set concentrations. The control device regulates the temperature of the air in the compartment, and the oxygen concentration and the carbon dioxide concentration of the air in the compartment on the basis of a state indicator (sugar content, for example) of fresh food (7) measured by the state indicator sensor (15).
