Abstract
The object of this study is an internal heat transfer/external promote crystal small coil gas hydrate cool storage device.HCFC-141b hydrate is the cool storage medium, and water is secondary refrigerant . This paper studies on the influence of different structural parameters on storage tank heat transfer characteristics, such as the coil arrangement and coil spacing. This paper builds nine tubes model. And it uses fluent to simulate the temperature field variation of the model. In order to make the research easier, this paper fixes other variables and studies for a variety in the course of studying. An analysis of the temperature variation of the four points was carried out. By comparing aligned arrangement and staggered arrangement, we can draw some conclusions.(1)Coil spacing has great influence on the heat transfer efficiency of cool storage tank.(2)The temperature variation of aligned arrangement is faster than staggered arrangement. And within a certain time, the final temperature of aligned arrangement is lower than staggered arrangement.
