Abstract: New refrigerator odor will affect the first experience of consumers, and relevant research is becoming more and more important. By smell evaluation method, the phenomenon of high odor level was found in the new refrigerators on the market. According to the gas component analysis, the new refrigerators contained hydrocarbons, benzene, aldehydes and esters, which were mainly derived from EPS foam, plastic parts and adhesive materials. On the basis of the experimental research, the research on the odor improvement of new refrigerator materials and components and the odor removal method of the whole refrigerator also provides theoretical guidance for the following new refrigerator odor improvement.

Key words: New refrigerator odor, Smell evaluation, Gas component analysis, Odor improvement
