热对工作的生产率以及居住者对周围环境的满意度都有很大的影响。本研究的目的是评估的含义，热环境条件下的人/假人在通风空调空间使用CFD模拟。模拟了一个办公室空调系统内的风速、温度、辐射温度等环境参数的热分布。通过基于真实的实验室研究和真实的案例研究的受控条件，利用实验研究的设计，这些案例研究后来被用作实地研究的外部有效性。在ANSYS工程仿真软件中建立了办公环境的模型。得到了热场分布、PMV的空间分布，直观地说明了热场状况。PMV的分布表明，在23 °C的操作温度下，PMV处于舒适水平。在23 °C手术温度下，人体皮肤附近的PMV值为0.79。研究结果为工程师提供了有用的信息，特别是在设计空调系统，以设计和建立一个舒适的室内环境气候，特别是在办公环境。
Thermal have significantly impact the productivity of work as well as the occupants’ satisfaction to their surroundings. The objective of this study is to evaluate the implication of thermal environmental conditions to human/manikin in a ventilated air conditioning space using CFD simulations. The thermal distributions of environmental parameters, which were air velocity, air temperature, radiant temperature, inside an office room with air-conditioning system were simulated. The design of experimental study was utilised through the controlled conditions based on the real laboratory studies and real case studies which were later on utilised as the external validity of the field studies. The model of the office environment has been built in the ANSYS Engineering simulation software. The thermal distributions, spatial profiles of PMV are obtained to illustrate thermal conditions intuitively. The distribution of PMV indicated that operative temperature at the 23 °C shows that the PMV is at the level of comfort. Meanwhile the value of PMV for the operative temperature at 23 °C is at 0.79 near the skin of manikin. The research outputs provide useful information for engineers especially in designing air-conditioning system in order to design and build a comfortable indoor environment climate especially in the office environment.
