Abstract This paper reports on the QuestTM II (QUality and Energy in Storage and Transport) development project run by Wageningen UR Food & Biobased Research, Maersk Line and Carrier Transicold. The aim of the Quest II development project was to improve the control of refrigerated marine container (reefer) units with the objective of maximizing energy efficiency in chilled mode operation without impairing produce quality. Lab testing research on produce quality revealed the limits by which deviations from the optimal transport temperatures are acceptable. Those limits were used in the design of the Quest II algorithm. Quest II control reduces energy consumption in chilled mode operation by 65% compared to non-Quest control. The savings are achieved by replacing continuous throttled compressor operation by an ON/OFF compressor control, and by automatically optimizing internal air circulation with heat load instead of continuous operation at maximum internal air circulation. Extensive produce quality research and hundreds of field trials reveal no adverse effect on produce quality while using the Quest II algorithm.
