家电产品生命周期评价边界界定研究

Study on defining life cycle assessment boundary of electrical appliances

产品在其生命周期过程中,不仅要与环境发生关系,而且还与其它产品系统发生关系,因此在对产品系统进行生命周期评价之前,首先要明确评价的目标以及产品评价系统的范围,从而对产品系统进行准确的评价。该文根据产品生命周期评价系统边界的确定原则,结合现有产品的生命周期过程,确定最佳的产品生命周期评价的范围,从而确保产品生命周期评价的准确性。

In its life cycle process, a product not only relates with the environment, but also with other products. Therefore, before the product life cycle assessment （LCA）, a sound knowledge of the objective and scope of the product evaluation system is needed in order to evaluate the products accurately. In this paper, according to the defining principles of product LCA system boundary and the current product life cycle process, the optimal boundary of product LCA system is defined to ensure the accuracy of the evaluation.
