Pressure refrigerant at cabinet outlet, mean value p8 [105 Pa]陈列柜出口制冷剂压力平均值 4.42 4.49 4.84
Superheat at cabinet outlet during running time, mean value [K]运行期间陈列柜出口过热度平均值 7.87 7.99 6.8
Evaporation temperature during running time, mean value θmrun [ºC]运行期间蒸发温度平均值 -9.4 -8.96 -6.9


前两台柜温偏高，在规定时间内不能把温度拉下来，请高手分析下

分体式陈列柜，蒸发器靠膨胀阀调节流量，外机为实验室设备，变频机
