水合物蓄冷系统分析

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。不同种类水合物系统火用效率取决于形成气的形成温度和压力

EXERGY ANALYSIS OF GAS HYDRATE SYSTEM AS COOL STORAGE MEDIUM

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.
