摘要
随着的不断提高,资源枯竭和环境污
染逐渐成为困扰人类的两个长期的、严重的问题。建筑能耗占总能耗的 30%,
因而,节能建筑对我国可持续发展至关重要,利用太阳能为人类服务的太阳能建
筑以它得天独厚的条件应用而生。
本文以西安市浐灞农村山区的某实体墙式集热蓄热墙被动式太阳房为研究
对象。根据文献资料,对研究模型的围护结构和集热蓄热墙的主要部件的参数和
结构进行了优化设计选择,为研究对象的设计提供参考依据。应用理论计算方法
对所研究的太阳房的室内热工(供暖率 SHF、所需辅助热量Qamx 、节能率 ESF)
进行了详细的计算,并预测了太阳房在采暖期室内各月的平均温度,为新农村太
阳房的室内热工设计提供了理论依据。最后,通过 Fluent 软件对太阳房模型的温
度场、速度场进行了数值模拟,模拟计算出太阳房模型的室内平均温度,并与理
论计算结果加以分析比较,验证了理论计算结果的正确性。
通过本文的研究,为被动式太阳房在西安地区的可行性奠定了理论基础,对
普通建筑的节能也具有重要的参考价值。

Abstract
With the sustainable development of national economy, the continuous
improvement of people's living standards, resource depletion and environment
pollution gradually e human two long –term and serious problem. Building
energy consumption accounts for 30% of total energy consumption, therefore,
Energy-saving building is very important to the sustainable development of our
country, solar building applications of use of solar energy for human service for its
advantageous conditions application.
This paper, taking a passive solar house with thermal heat-storage wall of
ChanBa rural mountain area of xi'an. Through check informations and documents,
taking the parameters and structure of the maintenance structure and a major part of
the thermal heat-storage wall of the research model for optimized design choices,
provide a reference basis for the research object of design. Application of theoretical
calculation method for the study of indoor thermal environment of the solar house
(heating rate SHF, the auxiliary heat, energy-saving rate of ESF) are calculated in
detail, and predict the indoor average temperature
