要对热回收装置的节能效果进行定量分析，必须通过对全年的动态分析才能实现，仅用传统的冬、夏季典型工况的设计方法是无法满足要求的。本文以一幢办公写字楼为例，选取具有典型气候的哈尔滨、广州两城市，利用建筑热环境能耗模拟软件Dest对两地新风能耗进行模拟，比较全热与显热交换器在上述两地的节能情况，进而提出2种热回收装置在应用时需遵守的原则。%Quantitative analysis of heat recovery equipment＇s energy-saving effect must be achieved by dynamic analysis throughout the year, only the design method of traditional winter and summer typical conditions can not meet its requirement. The paper takes an office building for example, chooses Harbin、 Guangzhou with the typical climate, the Dest energy consumption simulation software was used to perform simulation under two fresh air energy consumption, energy savings with the total heat exchanger and significant heat exchanger in the two places was compared, and the principle of the application with the two heat recovery equioments was advanced.
