摘要
地埋管地源热泵系统取热量和放热量的平衡对地埋管地源热泵系统长期稳定运行尤为重要,其系统取热量和放热量均取决于建筑物的冷热负荷。采用DeST软件对典型气候区典型建筑的全年逐时负荷进行模拟并分析其特性,酒店和医院建筑的负荷稳定性较差,持续性较强,商场、住宅和办公类建筑负荷稳定性较强,持续性较弱;严寒地区和夏热冬冷地区全年累计冷热负荷及空调季累计冷热负荷的不平衡率较高,而寒冷地区不平衡率较低。
In the ground source heat pump system,the balance between the heat taken and the heat released is particularly important for the long-term stable operation of the ground source heat pump system. The amount of the heat taken and the heat released is depend on the cooling and heating loads of the building. This paper simulates the annual dynamic load of the typical buildings of typical climate are though DeST,and analyzes its characteristics. The load of the hotel building and the hospital building is poor stability and strong continuity,the load of the residential housing and the office building and the department store building is poor continuity and strong stability. The rate of imbalance of the accumulated annual cold-hot load and the accumulated cooling-heat load in the air-conditioning season in severe cold region and hot summer and cold winter region is higher,but it’s lower in cold region.
