Research progress on phase change heat of gas hydrates
摘要
Abstract
Gas hydrates can be employed as a special phase-change material,as they have variable phase change heat changes during their formation or dissociation. This article summarizes the researches of phase change heat of gas hydrates from their measurements and applications. The direct and indirect methods of determining the phase change heat of gas hydrates are compared and analyzed in this work. The direct method is accomplished by using differential scanning calorimetry (DSC) while the indirect calculation method is achieved by Clausius-Clapeyron equation on basis of hydrate phase equilibrium data. The applications of phase change heat of gas hydrates are summarized comprehensively. Especially,the gas hydrates as the cold storage media in air condition systems are introduced in detail. The cold storage based on gas hydrates are discussed from cold storage media and cold storage devices. The key points and difficulties on the applications of phase change heat of gas hydrates are also pointed out. This paper is prone to provide a guide for the further utilization of phase change heat of gas hydrates.关键词
