比较了两类热学参数——(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(火积)损失和传质(火积)损失。(火积)损失分析可以为优化热湿环境营造过程提供指导。 Comparing the two types of thermal parameters - (or entropy), (fire product) in the analysis of the construction of hot and humid environment, the applicability of the process.  (or entropy) is the thermal parameter to study the conversion process of thermal power. The selection of reference state has great influence on the conclusion of the analysis. This paper introduces the physical concept of (fire product) and its application in the field of heat transfer. Attempts are made to study the process of creating a heat and humidity environment with heat and mass transfer process as the thermal parameters. The heat transfer (FA) loss and mass loss (mass loss) of a typical hot and humid environment case were analyzed. (Fire Product) Loss Analysis can provide guidance for optimizing the heat and humidity environment creation process.
