EFFECTS OF PRODUCT USAGE SCENARIOS ON ENVIRONMENTAL PERFORMANCE FOR ROAD TRANSPORT REFRIGERATION UNITS

摘要

A significant issue for the transport refrigeration industry is its high use of non-renewable energy for both motion and refrigeration. With the goal of reducing the environmental footprint, this study is focused on the Life Cycle Assessment (LCA) of Truck Refrigeration Units (TRU). Contrary to most studies about TRU, this study considers alternative impact categories, including energy consumption, refrigerant fluids and their associated impacts. The LCA reveals that the operation phase is a significant source of environmental impact, while the usage-scenario also has a high influence on the impact. The purpose of this paper is to demonstrate the weight of the transported product profile (frozen or fresh), type of transport (distribution or long haul) and the operating mode (continuous run, start/stop) on the environmental footprint of transport refrigeration. Finally, the LCA results highlight the necessity to consider the role of customer behavior on the environmental performance of transport refrigeration units.
