Research and analysis on ecological evaluation technology of air conditioner

The EU ErP Directive set up the framework requirements for entire life cycle of ecological design of energy-related products. This paper studied the ecological evaluation technology of air conditioning, considered environmental impact on each stage of life cycle of the product from design, manufacturing, transportation, disposal. Ecological design special software was used for quantitative analysis of air conditioning products. The study draws a conclusion: the use stage of air conditioning is the core stage of environmental impact, environmental impact in manufacturing stage, sales stage, and the end of life (EOL) stage is very small; in the main components of the product, two assembly (evaporator assembly and the condenser assembly) cause the strongest effect on the environment. The product energy efficiency significantly improved after technical improvement.
