Title:
GAS SUPPLY DEVICE AND REFRIGERATION DEVICE FOR CONTAINER INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2016161191
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas supply device capable of introducing outside air to the inside of a container even when a pressure of the inside air of a container is higher than a pressure of the outside air, and a refrigeration device for a container including the same.SOLUTION: A gas supply device includes: a first pump mechanism 31a; a second pump mechanism 31b; and an air circuit 3 in which a first adsorption part 34 and a second adsorption part 35 are connected and air circulates. The air circuit includes a circulation switching mechanism 65 for switching an air circulation state in the air circuit 3 between: a first circulation state for supplying nitrogen concentration air to the inside of the container by the second pump mechanism 31b; and a second circulation state for supplying the air having the same composition as that of the outside air in the air circulation circuit 3 to the inside of the container by the second pump mechanism 31b.SELECTED DRAWING: Figure 4
