摘　　要：本文讨论了对原有制冷剂的替代品R1234ze(E)在替代后的在热泵水果干燥机上应用的环保性能,采用生命周期评价的方法,从非生物资源消耗潜能(ADP)等8个环保指标进行评价,并通过调研国家环保需求,计算综合评价指标以进行新制冷剂的综合环境影响评价。结果表明:R1234ze(E)制冷剂机组在减碳性能方面突出,较之R134a机组提升16.97%,但是其他指标的表现均不同程度的劣于R134a机组。综合评价各个环境指标,两机组表现相近,可以认为现阶段没有必要对原机组进行制冷剂替换,但是未来可以考虑将其运用在新制造的机组中。The environmental impact of replacing the original refrigerant is evaluated in this paper,with a new refrigerant R1234ze(E)in a heat pump fruit dryer using the life-cycle assessment methodology.The evaluation considers eight environmental indicators,including abiotic resource depletion potential(ADP),and calculates comprehensive evaluation indexes based on national environmental protection requirements.The aim is to provide a comprehensive environmental impact assessment of the new refrigerant.The results shows that R1234ze(E)refrigerant unit have outstanding carbon reduction performance,which is improved by 16.97%compared with R134a unit,but the performance of other indicators is worse than R134a unit.Comprehensive evaluation of various environmental indicators shows that the performance of the two units is similar.It can be considered that there is no need to replace the refrigerant in the original unit at the present stage,but it can be used in the new manufacturing unit in the future.
