摘要
在现代蓄冷空调和城市集中供冷中，冰浆是一种有效的蓄冷和输送冷量的介质，其流动摩阻特性和传热性能是实际工程应用中的必要的基础数据，但是，人们对此了解甚少。本文通过对冰浆的流动摩阻特性和传热性能的实验研究，得到冰浆流动摩阻计算的经验公式，以及采用冰浆作为传热介质时表冷器的特性，同时和常规冷冻水的特性进行了比较分析。
In modern air conditioning with ice cooling storage and districtcooling ,ice slurryis a kind of effective materialforcooling storage andfortransmittingcoolthermalenergy.Thefrictionloss characteristicsin pipes and its heat transfer performance are the most important fundamental data in engineering ,and till up now ,it was known little .In this paper,the experimentstudy has been madeto understand the hydraulic perfor mance and the heattransfer performance ofice slurry.The authors have also madethe analysisto comparethe results with the performance ofthe pure water.Some empiricalcorrelations have been presented.
