CONTAINER REFRIGERATING DEVICE Russian patent published in 2017 - IPC F25D11/00 

FIELD: machine engineering.

SUBSTANCE: refrigerating device for the container contains a refrigeration circuit, a detector for determination of oxygen concentration inside the container, a device for supplying gas mixture. If oxygen concentration inside the container measured by oxygen concentration sensor is higher than oxygen concentration of the gas mixture, the container is supplied with gas mixture which has oxygen concentration below oxygen concentration of external air and above the target concentration. The concentration of oxygen in the inner part of the container is reduced to the level of oxygen concentration of gas mixture by supplying gas mixture into the inner part of the container and is further reduced to the target concentration by means of plants breathing. This properly controls the concentration of oxygen in the inner part of the container (11).

EFFECT: reduction of plant freshness decrease.
