摘　　要：为控讨CO_2水合物蓄冷技术,从水合物浆体热力学原理入手,分析CO_2水合物浆蓄冷量的构成;依据Clausius-Clapeyron方程、CO_2水合反应方程以及质量守恒定律,建立了浆体显热和潜热的计算模型;采用通过实验研究与理论推导相结合的方法计算得出CO_2水合物的蓄冷量。研究表明:浆体中水和CO_2气体的量越大,水合物浆蓄冷、释冷温差越大,CO_2水合物浆的显热量越高;水合物生成量越大,相平衡温度越低,CO_2水合物浆的潜热量越高。该研究为确定CO_2水合物浆的蓄冷量奠定了基础。This paper is focused on the study on the an important theoretical basis for the realization of carbon dioxide hydrate cool storage technology. The study starting from the thermodynamic principle of hydrate slurry consists of an is analysis of the cool storage amount composition of carbon dioxide hydrate slurry; the development of the calculation model of slurry sensible heat and latent heat using Clausius- Clapeyron equation, carbon dioxide hydrate reaction equation, and the law of mass conservation; and the calculation of the cold storage of carbon dioxide hydrate slurry using the method of experimental research combined with theoretical derivation. The research shows that a larger amount of water and carbon dioxide in slurry and a larger temperature difference of storage and discharging temperature are associated with a higher sensible heat of carbon dioxide hydrate slurry; a larger hydrate formation and a lower phase equilibrium temperature is associated with a higher latent heat of carbon dioxide hydrate slurry. The study may provide a foundation for determining the cold storage capacity of carbon dioxide hydrate slurry.
