水合物蓄冷系统分析

EXERGY ANALYSIS OF GAS HYDRATE SYSTEM AS COOL STORAGE MEDIUM

水合物蓄冷技术，其相变温度与空调工况相适应，相变潜热大，传热性能优良，成为极具潜力的蓄冷新技术。本文对水合物蓄冷过程进行火用分析，找出影响内部火用损失及外部火用损失的主要因素，对提高系统火用效率提出了改进的措施，得出结论：火用效率和热效率随蓄冷周期数的增加而增大，并趋向于一稳定最大值。

Cool storage in one of the mose effective methods to use off peak electricity.Gas hydrate cool storage technique is regarded as a promising technique because of its proper boiling temperature and high heat capacity.This paper deals with exergy analysis by using exergy transfer model.The conclusions are as follows:exergy efficiency is increasing with the number of cool storage and release circle,finally gets their maximum value;exergy efficiency of every kinds of hydrate gas system is affected by hydrate forming temperature and pressure.
