摘要:建立了基于Airpak的VRV加新风空调系统模型和一次回风空调系统模型，模拟得到夏季两种工况下的室内气流的温度场、速度场分布状况，并采用PMV-PPD及空气龄等指标对室内人员热舒适性及空气品质进行评价，结果表明两种方案工作区的风速均能达到舒适性空调的要求，人员无明显吹风感，一次回风空调系统相比VRV加新风空调系统：气流扰动较小，人员呼吸区温度波动较小，新鲜空气能够及时送达，室内空气品质较好
Abstract: This paper establishes models of the VRV & fresh air conditioning system and the primary return air conditioning system by using the software of Airpak, to simulate the temperature field and velocity field distribution of indoor air flow under two conditions in summer, and then to evaluate indoor thermal comfort and air quality by adopting the indexes like PMV-PPD and air age. Results show that both the wind speed of two schemes can meet the requirements of comfort air conditioning, without obvious sense of blowing for people. Compared with the VRV & fresh air conditioning system, the primary return air conditioning system has smaller air flow disturbance, smaller temperature fluctuation in respiratory area, and better indoor air quality with timely delivered fresh air.
