The work aims to construct a carbon footprint accounting system for low-carbon designed CMF of refrigerators and to provide tool support for enterprises to achieve low-carbon manufacturing and energy-saving emission reduction through CMF design. First, based on the carbon footprint accounting process of product, the carbon emission sources in the CMF design process of household refrigerators were identified. Then, taking into account the carbon emission factors of the refrigerator panel processing, a carbon footprint accounting model was established. Finally, a low-carbon designed CMF carbon footprint accounting system for refrigerators was constructed based on the dimensions of calculation and data management. Through the carbon quantification analysis of the CMF design scheme for refrigerators, the study optimizes the CMF design scheme according to the carbon evaluation results, carries out green and low-carbon optimization of the production process, and provides forward-looking guidance for low-carbon design decisions on refrigerators.
