摘　　要：在远置冷凝机组冷藏陈列柜的电能消耗实验中，分别安装电子膨胀阀与热力膨胀阀对冷藏陈列柜进行控制，对比耗电量。实验结果表明，在电子膨胀阀控制下的冷藏陈列柜耗电量略高于在热力膨胀阀控制下的耗电量，如何在冷藏陈列柜中使用电子膨胀阀时提高能效，需要做进一步的研究。In the electric energy consumption experiment of refrigerated display cabinet with remote condensing unit, electronic expansion valve and thermal expansion valve are respectively installed to control refrigerated display cabinet. Then the contrast of power consumption is gotten. The experimental results show that the power consumption of refrigerated display cabinet under the control of electronic expansion valve is slightly higher than that of thermal valve control. How to use electronic expansion valve to improve energy efficiency in the refrigerated display cabinet, it means further research needs to be done.
