Title:

REFRIGERATION UNIT FOR CONTAINER

Document Type and Number:

WIPO Patent Application WO/2015/049840

Kind Code:

A1

Abstract:

In order to generate a gas mixture for adjusting the oxygen concentration in a chamber of a container while decreasing the weight of the device as a whole, a gas mixture supply device is provided in this refrigeration unit for a container. The gas mixture supply device is provided with adsorption columns (34, 35). When air is supplied to one of the first adsorption column (34) and the second adsorption column (35), the adsorption columns (34, 35) are pressurized and oxygen in the air is adsorbed by an adsorbent. When air is sucked out from the other of the first adsorption column (34) and the second adsorption column (35), the adsorption columns (34, 35) are depressurized and oxygen adsorbed by the adsorbent is desorbed. A gas mixture containing the oxygen desorbed from the adsorbent is supplied to the chamber of the container (11).
