摘要
针对溴化锂冷水机组在水下航行器中的性能展开研究,对溴化锂冷水机组各换热设备进行建模,利用MATLAB编程求解,并通过实地测试验证模型的准确性,然后利用模型对溴化锂吸收式冷水机组进行性能分析,最后通过将其应用于某一水下航行器,对冷水机组耗能进行定量设计计算。实地测试能效比(coefficient of performance,COP)为1.07~1.38,与模型计算得到的COP最大相对误差为2.94%,满足精度要求;热源温度、冷却水进口温度和冷冻水进口温度对机组COP影响较大;水下航行器冷水机组COP为1.29,乏汽耗量为0.380 kg/s,单位冷量蒸汽耗量为1.366 kg/kW·h,仅占二回路蒸汽流量的0.6%,对于水下航行器的续航能力基本无影响。
The performance research of lithium bromide chiller in underwater vehicle is studied in this paper.Firstly,the heat-exchange equipment of lithium bromide chiller was modeled,and the lsqnonlin minimization solution of constraint was carried out by Matlab programming,and the correctness of model was verified by the experiment.Secondly,the model was used to analyze the performance of the lithium bromide chiller.Finally,the energy consumption of the chiller of a certain underwater vehicle was quantitatively calculated.The results show that:the unit COP is 1.07~1.38 in the field test,and its maximum relative error is 2.94%compared with model calculated COP,meeting the accuracy requirements;heat source temperature,the cooling water inlet temperature and the chilled water inlet temperature have a greater impact on the unit COP;the unit COP of the underwater vehicle is 1.29,the dead steam consumption is 0.380 kg/s,and the unit cooling steam consumption is 1.366 kg/kW·h,which only accounts for 0.6%of the secondary circuit steam flow.There is basically no impact on the endurance capacity of the underwater vehicle.
