英文摘要：

The heat transfer coefficient was introduced. This paper discussed the effect factors of the heat transfer coefficient in direct-contact accumulators, such as the flow rate of heat transfer fluid, inlet temperature of heat transfer fluid, liquid PCM flow rates, liquid PCM temperature and nozzle sizing and other factors. The direct contact accumulators in various fields of applications were introduced for storage process. Point out the problems of practical applications and predict the emphasis of the research.
