摘要
本文以南京为例,研究夏热冬冷地区土壤源热泵系统中闭式冷却塔的运行特性。采用TRNSYS软件进行系统仿真模型的模拟计算,模拟了土壤源热泵系统中闭式冷却塔在气象参数影响下的换热性能,及换热量的变化情况。通过对模拟结果进行数据处理与分析,得出影响闭式冷却塔换热性能的主要影响因素。换热量的变化曲线可参照相对湿度的变化曲线,进而得出换热性能最佳的运行时间段。
Taking Nanjing as an example, the cooling tower operation characteristics of ground-source heat pump system in the hot summer and cold winter region was researched. The TRNSYS software will be used to carry out a numerical simulation of system simulation. The simulation models the influences of meteorological parameters on the cooling Tower of the soil source heat pump integrated with the cooling tower system. Via the simulation, it will obtain the heat exchange performance and changes in heat exchange amount of the cooling tower. With data processing and the analysis of simulation results, the main influence factors affecting of cooling tower heat transfer performance. In the change of the heat curve can be reference to the change of relative humidity, the optimal time of the heat exchange performance will be concluded.
