Résumé

To meet the upcoming challenge of environmental sustainability, refrigerated transport is required to address energy efficiency and use sustainable fluids, namely natural refrigerants, at the same time taking into consideration the typical constraints of mobile systems, i.e. space and weight, system complexity, reliability and ease of servicing and maintenance. In this study, the design of a R744 refrigeration system employed on a vehicle used for urban delivery of fresh products (4-5 kW at 0 °C) is considered. The effects of different system architectures, controls and components are numerically evaluated focusing on the trade-off between the increase of the unit complexity, leading to higher energy efficiency of the sole cooling system, and the decrease of the unit overall encumbrance and weight, leading to lower carbon footprint of the vehicle.
