摘要

利用绿电进行蓄热作为驱动热源,提出一种数据中心蒸气压缩-吸收式复合制冷系统,建立系统数学模型,模拟研究不同工质对(NH3/H2O,NH,/LiNO3,NH3/NaSCN,R32/DMF,R134a/DMF 和 R600a/n-octane)对吸收式制冷模式性能系数和绿电消纳能力的影响.结果表明,在不同工况下,采用NH,/LiNO3工质对时吸收式制冷模式性能系数最高,在0.496~0.635;在设计工况下,采用NH3/LiNO3工质对时系统绿电能效系数COPG和绿电消纳能力系数COGP最大,分别为0.833和2.307.考虑到吸收式制冷能效和绿电消纳能力,NH3/LiNO3工质对是更适合复合制冷系统的工质对.

Abstract

A vapor compression and absorption hybrid refrigeration system for data center using green power for heat storage as a driving heat source is proposed.Mathemati-cal model of the system is established,and the effects of different working pairs(NH3/H2O,NH3/LiNO3,NH3/NaSCN,R32/DMF,R134a/DMF and R600a/n-octane)on the COP and green power consumption capacity of the absorption refrigeration mode are simu-lated and studied.The results show that under different conditions,the system under ab-sorption refrigeration mode using NH3/LiNO3 working pair has the highest COP,reaching 0.496-0.635;under design condition,the system using NH3/LiNO3 working pair has the highest COPG and COGP,reaching 0.833 and 2.307 respectively.Considering the energy effi-ciency of absorption refrigeration and the green power consumption capacity,NH3/LiNO3 work-ing pair is more suitable working pair for the hybird refrigeration system.
