高温高湿环境下工商业储能液冷系统性能实验研究
Experimental study on liquid cooling system performance for commercial and industrial energy storage under high-temperature and high-humidity conditions
摘要
Abstract
With the continuous improvement in the energy density of commercial and industrial energy storage systems and the expanding range of applications,coupled with stringent thermal management requirements under high-temperature and high-humidity conditions,the potential risk of thermal runaway has become increasingly significant.However,experimental research on liquid cooling system performance in such thermo-humidity environments remains limited.This study investigates the operational characteristics and energy consumption of cooling source equipment,supply-return liquid temperatures in distribution systems,as well as cold plate surface and battery temperatures under continuous charge-discharge conditions in high-temperature/high-humidity environments(40℃/30%RH,30℃/30%RH,and 30℃/70%RH).Results demonstrate that,compared with 40℃/30%RH and 30℃/30%RH conditions,the start-stop frequency of compressors and fans decreased by 52%,total cooling system energy consumption increased by 28%,and the longitudinal weighted average battery temperature difference was reduced from 3.14℃to 2.82℃.Under high-humidity conditions(30℃/70%RH),when the supply liquid temperature was increased from 20-25℃to 24-28℃,system energy consumption decreased by 22%,with the maximum battery cell temperature rising by 3℃.The average maximum temperature difference decreased by 22.56%,and the longitudinal average temperature difference was reduced from 2.89℃to 2.80℃.Ambient temperature,humidity,and supply liquid temperature showed no significant impact on the longitudinal temperature difference across battery cells within the pack.关键词
