摘　　要：本文基于寿命期气候性能LCCP概念,加入环境温度变化、冷藏运输车型、车速、制冷柜的COP和驱动方式、运输距离等影响因素,提出了科学评价食品冷藏运输过程LCCP的计算方法,并对12种冷藏运输车,在六个城市、不同冷藏温度及不同寿命期限内,使用R404A、R410A、CO_2三种制冷剂的LCCP进行了对比评价。结果表明:环境温度较高的城市,LCCP较大;与CO_2及R410A相比,R404A的LCCP最大;冷藏温度越低,能耗越大,LCCP越大;相比于使用主发动机或电驱动制冷柜的冷藏车,使用辅助发动机驱动的冷藏车的LCCP较大。Based on the concept of LCCP （Life Cycle Climate Performance）, a scientific calculation method for refrigerated food transportation was developed, with full consideration of ambient temperatures, refrigerated transportation vehicles, speeds, COP and driving pattern of refrigerators, transportation distances and etc. Using this method, a comparative evaluation was conducted for 12 different refrigerated trucks, in 6 cities, using three refrigerants as R404A, R410A and CO2, at various refrigeration temperatures and lifetimes. The results showed that LCCP is larger in the cities at higher ambient temperature; Using R404A, LCCP is greater than the ones using CO2 and R410A ; LCCP is greater with lower refrigerator internal temperature and higher energy consumption; Driven by auxiliary engine, LCCP is greater than the ones driven by main engine or electric motor.
