Abstract: Disclosed is a transport unit (100) and a method (400) of controlling an atmosphere therein. The transport unit (100) has a compartment (200) for holding cargo (110), an atmosphere control system (300) for controlling an atmosphere in the compartment (200) and first and second ports (210, 211) for supplying conditioned gas from the atmosphere control system (300) to the compartment (200). The first and second ports (210, 211) open into the compartment (200) at different, spaced-apart locations in the compartment (200). The atmosphere control system (300) is operable in a first mode of operation, in which the atmosphere control system (300) is configured to supply conditioned gas to the compartment (200) through the first port (210) at a higher supply flow rate than through the second port (211). The atmosphere control system (300) is further operable in a second mode of operation, in which the atmosphere control system (300) is configured to supply conditioned gas to the compartment through the second port (211) at a higher supply flow rate than through the first port (210).

Abstract: A method for controlling ripening of vegetabile produce in a second transport unit (1B) is disclosed. The method comprises obtaining, at the second transport unit (1B), ripening data from a first transport unit (1A), which first transport unit (1A) carries produce from a same geographical area as the second transport unit (1B); correlating, at the second transport unit (1B), the obtained ripening data with a scheduled delivery date for the second transport unit (1B); and controlling, at the second transport unit (1B), a ripening process of the produce during transport based on the correlated data for achieving a desired ripening stage in the produce at the scheduled delivery date.
