Advances in the Refrigeration Aspects of a Shipping Container

Container refrigeration is an important technology in the modern world, where many perishable products are transported in containers which are estimated to be in excess of a quarter million units in current use world-wide. This paper reports on a multi-prong research program, which was initiated to improve the thermal performance of a container refrigeration ststem. The areas examined include studies on system modeling on both full-load control, evaporator studies to enhance its effectiveness, and incorporation of fuzzy logic control to bring about better temperature control.
