Introduction Life Cycle Assessment (Life Cycle Assessment, LCA) is a product in its Life Cycle impact on the environment are systematically and quantitatively evaluated.1993 SETAC (Society of Environmental Toxicologyand Chemistry) described the LCA into four interrelated components of triangular model, respectively is the target definition and scope definition, inventory analysis, impact assessment and improvement of the evaluation, as shown in figure 1.ISO (International Organization for Standardization) in June 1997 lifted the IS014040 standard, remove the SETAC framework to improve the evaluation phase.IS014040 life cycle assessment can be divided into contact with each other, constantly repeated four steps, determine the purpose and scope of, inventory analysis, impact assessment and results explain, as shown in figure 2 [1,2].
Life cycle assessment framework Goal and scope Inventory analysis Impact assessment explanation Direct application Product development and upgrading Strategic planning Public policy making marketing Fig. 2 Theoretical framework in life cycle assessment (ISO) Life cycle energy consumption of clean air-conditioning system Pharmaceutical industry to purify the air conditioning system energy saving transformation after the life cycle total energy consumption is equal to the total life cycle energy consumption and clean air-conditioning system reform before modification of the structure of system, reform part of the equipment material production energy consumption and subtracting for purifying air conditioning system to reduce system energy consumption, see formula expression (1)： （1） where ——After transforming to purify the air conditioning system life cycle total energy consumption

However its synthesis at low temperatures yields PANI with molecular weight five to ten times higher than that synthesized at room temperature [3].Although it has easy to synthesize polyaniline through different methods but it has very rich doping/dedoping chemistry made it a promising material for gas sensors [4-5].
For crystal structure analysis, the prepared samples were characterized by powder X-ray diffraction (XRD) using Cu Kα radiation with Shimadzu 7000 Diffractometer and field emission scanning electron microscope (FESEM) with Ziess, model Supra 55.
