空调系统变水温运行能耗特性研究

摘要

以杭州市某办公楼的地源热泵主机作为研究对象，通过改变主机的供水温度并跟踪分析能耗分项计量平台的实时能耗数据，总结了夏季供冷季和冬季供暖季的供水温度与主机COP以及供水温度与主机能耗之间的规律，综合分析典型气象年数据以及主机的年运行能耗，提出针对本工程的分阶段变水温的控制策略。%This paper takes the ground source heat pump (GSHP) of an ofifce building in Hangzhou as the research object. By changing the supply water temperature and tracking real-time energy consumption data, it obtains the relation between COP and supply water temperature as well as the relation between energy consumption of GSHP and supply water temperature. It gives the operating strategy on the basis of analyzing the annual operational energy consumption and typical meteorological year.
