Romanian Reefer Trade Face to Face with Efficiency and Environment

Marine refrigeration plants must address two major matters: efficiency and environment. This paper approaches efficiency from the ice storage point of view. Because this technology is performs well on shore, we propose to adjust it for on board the ship. On the basis of the excellent results obtained by CEMAGREF laboratories, we made a calculation for an Ice Balls Storage System adapted for a fishing vessel, in order to perform in the Romanian fishing sector. The results was a smaller distribution ductwork. The necessary daily refrigerant requirements are 47% smaller than a conventional system. The environment is one of the big challenges that Romanian reeferis facing. This is why we present ammonia as being a promising refrigerant for the reefer trade. The comparison made in this paper between R22, a traditional refrigerant for the Romanian fleet, and ammonia shows that ammonia is the perfect alternative refrigerant to R22.
