EXPERIMENTAL STUDY OF HFC-134a GAS HYDRATE FORMATION PROCESS
摘要
Abstract
Refrigerant gas hydrates have brilliant prospects as cool storage material of air-conditioning system. In this paper, when the ratio of the weight of HFC-134a to that of water is 2. 17%, systematic experiments have been carried out on the formation process of the HFC-134a gas hydrate including of the phase equilibrium, the influence of supercooling degree, and the influence of agitation. The results indicate that the critical decomposition temperature and the critical decomposition pressure of R134a hydrate is 283.4K and 414K respectively, the formation of gas hydrate was promoted with increasing the supercooling degree and the agitation. However, it is desired that the supercooling degree is smaller.Therefore, it is important problem that the study of optimum of supercooling degree for cool storage system.关键词
