DYNAMIC VENTILATION CONTROL SYSTEM FOR REEFER CARGO HOLDS

摘要

The invention relates to control of the ventilation in vessel cargo holds carrying e.g. reefer containers. The purpose of the invention is to optimize the overall energy consumption related thereto, i.e. minimizing the total energy consumed by the cargo hold ventilation and cargo carrying units, in particular but not limited to reefer containers, in the ventilated cargo hold or holds. The invention continuously or with intervals measures a number of physical parameters, e.g. temperatures, related to the cargo hold or holds and to the ambient conditions, and utilizes the measurement results to establish one or more control signals to directly or indirectly control the ventilation of the cargo hold or holds in such way that the total energy consumption of the ventilation and the cargo carrying units is dynamically minimized as conditions change.
