摘要(Abstract)：

针对纯电动冷藏车制冷系统在高温环境中制冷性差和耗能严重等问题,搭建准双级压缩低压补气型冷藏车制冷系统试验台,试验研究了在高温32℃的库外环境中,库外风量和库内风量不同设定值对冷藏系统制冷性能的影响,结果表明:库外风量由4 500 m~3/h增大到9 000 m~3/h时,制冷量增大了0.2%～3.3%,系统C0P增大了2.3%～15.9%,库外风量为7 500 m~3/h时,系统总功率达到最小值8.14 kW,系统EER达到最大值2.167,此时风量最佳;库内风量由4 000 m~3/h增大到7 000 m~3/h时,制冷量增大了0.17%～3.4%,系统C0P增大了1.6%～16.9%,库内风量为6 000 m~3/h时,系统总功率达到最小值7.86 kW,系统EER达到最大值2.251,此时风量最佳。
For the problems of poor refrigeration performance and serious energy consumption in the refrigeration system of pure electric refrigerated trucks in high temperature environments,an experimental platform for quasi-two-stage compression lowpressure air-supplemented refrigerated truck refrigeration system was built.The experiment studied the influence of different setting values of the air volume outside and inside the refrigerating chamber on the refrigeration performance of the refrigeration system in the external environment of 32 ℃ high temperature outside the refrigerating chamber.The results show that:when the air volume outside the refrigerating chamber is increased from 4 500 m~3/h to 9 000 m~3/h,the cooling capacity is increased by 0.2%～3.3%,the system COP is increased by 2.3%～15.9%,and when the air volume outside the refrigerating chamber is 7 500 m~3/h,the system total power reaches a minimum value of 8.14 kW and the system EER reaches a maximum value of 2.167,at this time the air volume is optimal:When the air volume in the refrigerating chamber is increased from 4 000 m~3/h to 7 000 m~3/h,the cooling capacity is increased by 0.17%～3.4%,the system COP is increased by 1.6%～16.9%,and when the air volume in the refrigerating chamber is 6 000 m~3/h,the system total power reaches a minimum value of 7.86 kW and the system EER reaches a maximum value of 2.251,at this time the air volume is optimal.
