摘　　要：针对纯电动汽车双热源热泵系统,采用单一空气源热泵模式和双热源热泵模式进行系统实验,得到系统的性能参数,推得各部件损失占比等.结果表明：吸取1kW废热后,制热量和能效比最大,分别提高了46.58%和28.07%;部件相对损失占比最大的为压缩机46.64%~50.07%,其次是冷凝器30.09%~33.40%.For the dual source heat pump in electric vehicles,experiments were conducted in air source heat pump（ASHP）and dual source heat pump（DSHP）mode.The heating performance characteristics were obtained and exergy loss ratio was deduced.It turns out that the heating capacity is 46.58% higher than that without waste heat and the coefficient of performance（COP）is 28.07% higher at most.The compressor accounts for most exergy losses of up to 46.64% to 50.07% while the condenser reaches 30.09% to33.40%.
