摘要

 通过试验研究了浆体蓄冷空调中采用质量分数为20%的四丁基溴化铵(TBAB)溶液制备TBAB水合物浆体的方法.分别采用均匀、非均匀、带滤网的非均匀3种水合物浆体储存方式，以及2种水合物固体层熔化方式，通过比较温度、TBAB流量、压降和系统能效等参数的变化来分析不同制备方法所得换热器的换热性能.结果表明，采用带滤网的非均匀的储存方式比均匀、非均匀储存方式的能效比分别提高了14.3%和9.8%.

Abstract

 Tetranbutyl ammonium bromide (TBAB) clathrate hydrate slurry (CHS) has shown a promising application prospect in cold storage airconditioning. In the present study, TBAB CHS was generated from 20% (mass fraction) initial concentration aqueous solution in a cold storage airconditioning. Three TBAB CHS storage methods, i.e., homogeneous, heterogeneous and heterogeneous with filter, and two methods of melting the crystal layer on the wall of the heat exchanger determined by fixed time and by flowrate were utilized to generate TBAB CHS. Temperature, flowrate, pressure drop, image of TBAB CHS and coefficient of performance were obtained during the generation processes. It was found that heterogeneous with filter can enhance the efficiency up to 14.3% and 9.8% compared with the homogeneous and heterogeneous methods, respectively.
