摘　　要：简述了低温全新风系统的组成,给出了全空气系统能耗评价的数学模型,采用当量满负荷运行时间法对全新风系统和一次回风系统的全年总能耗量进行了分析和比较,结果表明:在某些工况下,低温全新风系统可以比常温一次回风系统节能,尤其是对于新风比较高的建筑,低温全新风系统具有更广阔的应用前景。Outlines the composition of the all cold outdoor air system and presents their mathematical models of energy consumption evaluation. Analyses and compares the annual energy consumption of the system and that of the system with primary return air using the method of equivalent weight full load operation time, and the results show that in some given conditions the annual energy consumption of this system can be less than that of conventional primary return air systems, especially to the buildings which have high percentage of outdoor air volume. The application of this system will be more widen in the future.
