项目摘要

The recent global environmental issues including earth warming due to carbon dioxide and ozone layer depletion by Chlorofluorocarbons are characterized by the facts that it takes a long time to resolve and that it is inherently international. Recently, the problems are getting more and more important both in academic and political standpoints.Most of all, the earth warming problem urges us to reduce the CO_2 emission. This means that thermal efficiency and the coefficient of performance(COP) should be greatly improved in the near future.Under these situation, our study will make it possible to realize the abovementioned improvement. The principal results obtained by our study are summarized below. (1) A new energy efficient system was proposed. The system incorporates the heat source part and heat storage part. The COP of the proposed system is estimated to be at least 2 - 3 times as larger as the existing methods. (2) The concrete energy system having given specifications were constructed and the computer software for the new energy efficient system was developed. (3) Using the above simulation codes, the computer simulations and parametrization were performed for the given systems. (4) The numerical simulation was carried out for melting heat transfer in the horizontal and spherical capsules. The experiment was also done to validate the theory. These results were utilized for optimal design of the above systems.

最近的全球环境问题，包括由于二氧化碳和臭氧层耗竭引起的地球变暖，其特征是解决了很长一段时间才能解决，并且本质上是国际上的。最近，这些问题在学术和政治角度越来越重要。最重要的是，地球变暖的问题敦促我们减少CO_2排放。这意味着在不久的将来应大大改善热效率和性能系数（COP）。在这些情况下，我们的研究将有可能实现上述改善。我们的研究获得的主要结果总结了下面。（1）提出了一个新的节能系统。该系统结合了热源部分和热存储部分。估计，所提出的系统的COP至少是现有方法的2-3倍。（2）构建了具有给定规范的具体能源系统，并开发了用于新的节能系统的计算机软件。（3）使用上述仿真代码，为给定的系统执行了计算机模拟和参数化。（4）进行数值模拟，以在水平和球形胶囊中熔化传热。还进行了实验以验证理论。这些结果用于上述系统的最佳设计。
