用于冷负荷占优型建筑的地源热泵复合系统模拟研究

GROUND SOURCE HEAT PUMP FOR COLD LOAD-DOMINANT BUILDINGS SIMULATION STUDY OF COMPOSITE SYSTEM

近几年来,各种建筑的中央空调系统都采用了地源热泵技术。采用逐时仿真的方法,对不同类型的地源热泵系统进行了设计和运行。对不同设计方案下的混合系统进行了逐时的仿真,并对其进行了仿真对比,得出了最优的设计及控制参数。分析结果显示,采用优化的地下水源热泵组合系统,能有效地解决地下热累积问题,并能在较长的时间内减少整个空调系统的投资。

In recent years,the central air conditioning system of various buildings has adopted the ground source heat pump technology.Different types of ground source heat pump systems are designed and operated.The hybrid system under different design schemes is simulated successively,and then the optimal design and control parameters are obtained.The analysis results show that using the optimized underground water source heat pump combination system,can effectively solve the problem of underground heat accumulation,and can reduce the investment of the whole air conditioning system in a long time.
