摘　　要：为深入研究空气源热泵对办公室供暖的效果,利用SolidWorks建立了带隔断的办公室三维模型,并用ANSYS软件模拟了在办公桌面加装物理隔断前后不同送风速度和送风角度对室内气流场的影响。结果表明:相较于无隔断桌面,加装隔断后室内空气流动更加均匀,办公区域风速降低。此外,在加装物理隔断后,给定1 m/s、1.5 m/s、2 m/s和3 m/s送风速度下,送风角度为30°时,室内温度较为均匀,但办公区域附近形成多个较大的涡旋,办公区域温度较高,且室内温度分层不明显。送风角度为60°和85°时,涡旋的尺寸和数量明显减少,气流场的病态性减弱,温度场变化较为明显,85°送风下办公区域整体温度偏低。2 m/s和3 m/s的空气流动强度较高,人体吹风感较强。综合考虑人体舒适度和房间内风速分布效果,2 m/s风速和60°送风角度工况较好。研究结果为合理优化办公区域工位布置及进一步提升供暖舒适性提供依据。研究结果为合理优化办公区域工位布置及进一步提升供暖舒适性提供依据。To investigate the impact of air source heat pumps on office heating,a three-dimensional model of an office environment with partitioned workstations was developed using SolidWorks.The airflow and thermal performance under varying air supply velocities and angles were simulated using ANSYS software,considering the scenarios with and without physical desk partitions.The results indicate that the installation of desk partitions leads to a more uniform indoor airflow distribution and reduces wind speed in the office area.At air supply velocities of 1 m/s,1.5 m/s,2 m/s,and 3 m/s,when the air supply angle is set to 30°,the indoor temperature distribution is relatively uniform.However,large vortices are observed near the workstation area,resulting in elevated temperatures and minimal thermal stratification.At air supply angles of 60°and 85°,the size and number of vortices are significantly reduced,mitigating airflow irregularities.The temperature field exhibits more pronounced changes,with the overall temperature in the office area being lower at an 85°air supply angle.High airflow intensities of 2 m/s and 3 m/s produce noticeable draughts,potentially compromising occupant comfort.Considering human thermal comfort and wind speed distribution,the optimal operating condition is identified as a 2 m/s air supply velocity with a 60°supply angle.These findings provide valuable insights for optimizing workstation layouts and enhancing heating comfort in office environments.
