摘要
综合分析了评价超低温氨用螺杆制冷机组性能和运行效率的四个基本综合评价原则,包括压缩机的可靠性;机组的节能装置效果;以及在部分负荷下的能效、制冷剂、噪声以及经济性。最后结合实际工程进行比较,为超低温速冻工程中氨用螺杆压缩式制冷机组的应用提供技术选型依据。
Comprehensive analysis of four principles of assessment of screw chillers with ammonia in ultra low temperature.Covering the reliability of compressor,effect of energy saving of the apparatus,energy efficiency and refrigerant noise level and economic at part load.Prompts a real project to provide references for the model selection of screw chillers with ammonia in ultra tempertture.
