摘要:

为定量分析被动式技术在长江流域不同气候条件下的节能效果,通过计算各项气候指标的变异系数,采用供暖度时数HDH16、空调度时数CDH28为一级指标,最冷月南向竖直面总辐照度和除湿度时数为二级指标,将长江流域分为4个一级分区和7个二级分区。针对每个分区利用EnergyPlus软件动态模拟了外墙外保温、节能窗、遮阳技术及自然通风的节能效果,统计了各项被动式技术条件下的非供暖空调时间。给出了各个单项被动式技术及集成被动式技术在不同城市的适宜情况并进行了优选排序,为被动式技术在长江流域的应用提供参考。

Abstract:

In order to quantitatively analyse the energy saving effect of passive technologies under different climate conditions, divides the Yangtze River basin into four primary zones and seven secondary zones by calculating the coefficient of variation of climatic indexes, and adopting the heating degree hours (HDH16) and the cooling degree hours (CDH28) as the first grade indexes, the total irradiance on the southern vertical surface in the coldest month and the dehumidification degree hours as the second grade indexes. Dynamically simulates the energy saving effect of exterior wall insulation, energy efficient windows, shading devices and natural ventilation for each subarea using the EnergyPlus software. Calculates the non-heating and air conditioning hours for each passive technology. Obtains the suitability of single and integrated passive technologies in different cities and gives the optimal ranking, which provides a reference for the application of passive technologies in the Yangtze River basin.

Keywords:YangtzeRiverbasin,climatezone,passivetechnology,non-heatingandairconditioninghour,optimalranking
