Refrigeration System Life Cycle Assessment Method

摘要

Basing on the exist environmental impact assessment method of the Refrigeration system, the paper establishes an approach of the inventory calculation model and environmental impact assessment model with a life cycle assessment, as the environmental impact assessment on the water heater as a case study, also calculates and analyses four indicators-the products' resource consumption, ozone depletion, energy intensity and global warming. The results indicate that the rank of the contribution value of the four indicators in life cycle is ozone depletion, global warming, energy intensity and resource consumption. The large parts of environmental impact of the water heater are the compressor, the refrigerant, the motor and the brass.
