北京办公建筑太阳能-土壤源热泵系统串联运行优化设计

摘要

The Solar-Ground Source heat pump system was briefly introduced on two different connections. The TRNSYS is utilized to build a model of a small office building in Beijing to simulate its operation in 20 years under two different connections and a variety of combinations of solar heat collecting system and buried pipe heat exchanger system. According to the simulation results, the optimal design is obtained with analysis on the Life Cycle Cost and the soil temperature recovery.%通过阐述太阳能-土壤源热泵系统联合运行2种不同串联运行模式下的工作原理。以北京市某小型办公建筑为例，应用TRNSYS仿真模拟软件建模，对2种串联运行模式下多种太阳能集热系统和地埋管换热系统的组合策略进行为期20年的运行模拟。以模拟结果为基础，综合系统全寿命周期成本以及土壤温度场恢复情况，得到最优设计方案。
