浅层地热能在常见民用建筑中的适宜性分析

Suitability analysis of shallow geothermal energy in common civil buildings

基于陕西省浅层地热资源及气候特征,选择陕西省不同气候区3个典型城市西安、榆林和汉中作为代表城市,针对办公、商业和居住3种类型民用建筑进行全年逐时负荷分析,从建筑负荷特性入手,确定供暖空调方案配置,进行经济性比较与分析,从而分析不同气候区不同建筑类型利用浅层地热能的适宜方案,为实际工程项目设计提供参考,也为我国其他地区利用浅层地热能提供参考。

Based on the shallow geothermal resources and climate characteristics of Shaanxi Province,this study selects three typical cities,Xi’an,Yulin and Hanzhong,in different climate zones of Shaanxi Province as representative cities,and carries out the hourly load analysis for three types of buildings,namely office,commercial and residential buildings,which are common in civil buildings.Starting from the characteristics of building load,this paper determines the configuration of HVAC solutions and compares the economics of the solutions,so as to analyse the appropriate solutions for the use of shallow geothermal energy in different building types for different climate zones.This will provide a reference for actual project design and also for the use of shallow geothermal energy in other regions of China.
