气体水合物蓄冷技术的实验研究

EXPERIMENTAL RESEARCH ON GAS HYDRATE COOL STORAGE TECHNIQUE

本文研究了间接接触蓄、放冷模式下，蓄冷罐内状态点在相图上的变化情况，得出了蓄、放冷过程中蓄冷罐内各层之间的传热特性数据，以及表面活性剂（正丁醇）的加入对蓄、放冷过程中的过冷度、气体水合物疏松度的影响，模拟了实用气体水合物蓄冷系统的蓄、放冷过程．

The track of system condition point of indirect contact system on temperature_pressure diagram is obtained. The heat transfer characteristic in the cool storage vessel during charging and discharging processes is described. N_butonol as surfactant is added into water to eliminate subcooling degree and gas hydrate porosity. The charging and discharging processes imitate those in actual cool storage system.
