夏热冬冷地区某综合楼空调冷热源优化研究

Comparison and analysis of cold and heat sources for air-conditioning system of buildings in hot summer and cold winter zone

根据夏热冬冷地区的气候特点、建筑使用功能和建筑周边资源现状,对某综合楼空调冷热源方案的选择进行比较研究。通过比较优化前后冷热源方案,对其初投资、运行费用、舒适性、稳定性等因素进行综合分析,结果表明当建筑规模较大且需提供空调及热水时,模块式风冷热泵(热回收)系统优越于多联机VRV加独立热源系统。

Comparison and analysis of cold and heat sources for air-conditioning systems of buildings were conducted with relation to the buildings＇ functions, energy resources and the climate character-istics in hot summer and cold winter zone. Comprehensive analysis was made on the investment, comfortability and reliability of the cold and heat sources before and after the optimization, The resuits show that module-typed air-cooled heat pump with heat recovery is superior to VRV with independent heat source system in the large-scale buildings that provide hot water and air-conditioning.
