Abstract
A method is provided for operating an active controlled atmosphere (CA) system to regulate the atmosphere in a cargo storage space. The controlled atmosphere system comprises: a plurality of gas exchange modules, each being operable to vary the level of a respective component gas in the cargo storage space, and/or at least one gas exchange module operable in a plurality of different modes to vary the level of a respective component gas in the cargo storage space; and a control module configured to control operation of each gas exchange module according to a plurality of different predetermined atmospheric control logics. Each atmospheric control logic defines operational gas exchange modules and/or operational modes for use over respective operational ranges of atmospheric conditions, and each atmospheric control logic is configured to cause operation of a different combination of gas exchange modules and/or modes over a comparable operational range, independently of any setpoints for gas component levels. The method comprises: the control module selecting an operational atmospheric control logic from the plurality of different predetermined atmospheric control logics for atmospheric control of the cargo storage space; and the control module controlling operation of each gas exchange module dependent on the selected operational atmospheric control logic to regulate the atmosphere in the cargo storage space.
