摘要
文章运用有限元技术,通过Airpak软件对地源热泵系统在制冷状态下为办公室人员带来的热舒适性进行数值模拟研究,计算不同送风参数下的温度场、速度场和PMV等评价指标,对比分析不同送风参数下的各个评价指标,最终确定上送分房间内最优送风温度为296K、最优送风速度为3.3m/s,模拟结果对实际工程中热泵系统在制冷状态下上送风房间内送风参数的设置提供一定的理论依据。
In this paper, the thermal comfort of the ground source heat pump system for office personnel under cooling state is numerically simulated by using the finite element technology and Airpak software. The evaluation indexes such as temperature field,velocity field and PMV under different air supply parameters are calculated, and the evaluation indexes under different air supply parameters are compared and analyzed. Finally, it is determined that the optimal air supply temperature in the upper air supply room is 296 K and the optimal air supply speed is 3.3 m/s. The simulation results provide a certain theoretical basis for the setting of air supply parameters in the upper air supply room under the refrigeration state of the heat pump system in the actual project.
