The growing energy consumption and thermal comfort of an air-conditioned room have attracted increasing public attention. As such, the performance of air-conditioning systems with two air supply modes for a simplified office room was studied by numerical simulation and physical experiment. An experimental investigation was developed in an environmental chamber to validate the simulation model. Numerical investigation was carried out subsequently for an office setting by the validated CFD model. The indoor thermal environment, human thermal comfort and energy utilization efficiency of two air supply modes were analyzed and compared in this study. The results showed that under both air supply modes, thermal stratification occurred in the model room, and the air flow velocity in the occupied zone was low. In addition, the results indicated that under 21 °C supply temperature, the air-conditioning system with bottom-supply mode provided better indoor thermal comfort of the occupied zone, but the energy consumption was higher than the side-supply mode.

空调房间越来越多的能耗和热舒适性吸引了越来越多的公众关注。因此，通过数值模拟和物理实验研究了具有两种供气模式的简化办公室空调系统的性能。在环境室中进行了实验研究，以验证仿真模型。随后通过验证的CFD模型对办公室环境进行了数值研究。对两种供气方式的室内热环境，人体热舒适性和能源利用效率进行了分析比较。结果表明，在两种送风方式下，样板房均发生热分层，所占区域的空气流速较低。此外，
