摘要

通过试验对在直接接触式气体水合物系统中非常有效的添加剂在直接接触式冰蓄冷系统中进行了研究

发现锌粉对直接接触式相变换热效果最好

而丁醇几乎没有效果

Abstract

An investigation on the effects of additives in direct contact ice thermal stora ge system which were very effective in direct contact gas hydrate thermal storage system was conducted by experiments. Among five additives

such as NaCl

CaCl 2

zinc powder

iron powder and butyl alcohol

it was found that zinc powder h as the best effect on volumetric heat transfer coefficient and butyl alcohol has no effect.It was also found that volumetric heat transfer coefficient increased with increasing quantity of iron powder and NaCl

while decreasing quantity of b utyl alcohol and zinc powder.The pattern of temperature distribution in cool storage cylinder has hardly any difference with increasing quantity of additive.From the investigation

it can be concluded that solid additives have the best resu lt on the direct contact ice thermal storage system.
