热学参数在建筑热湿环境营造过程中的适用性分析

摘要

Compares the applicability between exergy or entropy and entransy utilized in thermal-hygro environment building.Exergy or entropy is a thermological parameter to analyse conversion between heat and power, and selection of the reference state greatly influences the analysis results.Presents the physical concept of entransy and its applicability in heat transfer field.Tries out adopting entransy to study thermal-hygro environment building, which mainly consists of heat and mass transfer.Analyses the entransy losses of heat transfer and moisture transfer process in some typical thermal-hygro environment building examples.Entransy loss analysis can offer guidelines for optimization of thermal-hygro environment building.%比较了两类热学参数--(火用) (或熵)、(火积)在分析建筑热湿环境营造过程时的适用性.(或熵)是研究热功转换过程的热学参数,参考状态的选取对分析所得结论的影响很大.介绍了(火积)的物理概念及其在传热领域的应用,尝试利用(火积)作为热学参数对以热量、质量传递过程为主的热湿环境营造过程进行研究.分析了典型热湿环境营造案例的传热娠损失和传质(火积)损失.损失分析可以为优化热湿环境营造过程提供指导.
