A new CFD (Computational Fluid Dynamics) simulation for designing indoor climates is presented in this study. It is coupled with a radiative heat transfer simulation and HVAC (Heating, Ventilating, and Air-Conditioning) control system in a room. This new method can feed back the outputs of the CFD to the input conditions for controlling the HVAC system, and includes a human model to evaluate the thermal environment. It can be used to analyze the conditions of the HVAC system (e.g. temperature of supply air, surface temperature of radiation panel, etc.) and the heating/cooling loads of different HVAC systems under the condition of the same human thermal sensation (e.g. PMV.Operative Temperature, etc.)To examine the performance of the new method, thermal environments within a room, office and semi-enclosed spaces are analyzed. Using this method, the most energy efficient HVAC system can be chosen under the same PMV value.

本研究提出了用于设计室内气候的新的CFD（计算流体动力学）模拟。它与辐射传热模拟和房间中的HVAC（加热，通风和空调）控制系统相结合。这种新方法可以将CFD的输出反馈到控制HVAC系统的输入条件上，并包括人类模型以评估热环境。 It can be used to analyze the conditions of the HVAC system (e.g. temperature of supply air, surface temperature of radiation panel, etc.) and the heating/cooling loads of different HVAC systems under the condition of the same human thermal sensation (e.g. PM​​V.Operative Temperature, etc.)To examine the performance of the new method, thermal environments within a room, office and semi-enclosed spaces are analyzed.使用此方法，可以在相同的PMV值下选择最节能的HVAC系统。
