FloEFD暖通空调模块 – 让建筑环境CFD模拟提升到新的水平
最近发布的FloEFD暖通空调模块为FloEFD带来了诸多专门用于建筑环境模拟的功能。 FloEFD具有先进CFD（计算流体动力学）自动化方面的技术和功能，使用户专注于应用，而不只是数字。能够模拟空气流动，污染物扩散，建筑环境的热舒适性和热功率的真实三维物理模型，CFD的普及大大扩大了设计师范围。
乘员热舒适性和室内空气质量管理是绿色建筑设计关键的挑战。如ASHRAE标准55-2004（包括在空间热舒适性）和ASHRAE标准62.1-2007（包括可接受室内空气质量的通风（IAQ））可以通过CFD模拟来确定。 FloEFD的暖通空调模块能够模拟以下指标，设计空间时确保可接受热舒适的行为和IAQ水平最大化：
•预测平均投票（PMV）
•预计不满意百分比（PPD）
•可操作（舒适）温度
•通风装置温度
•空气扩散功能指数（ADP）
•污染物排除效率（CRE）
•当地空气质量指数（LAQ）
•气流角度
辐射传热是任何特定的建筑环境的热效率的中心。不管是否受短波太阳载荷或红外辐射转换的影响，FloEFD先进的辐射能力能够模拟的模型如下：
半透明固体（固体的辐射吸收）
不同波长辐射
光谱的定义
表面的镜面反射
折射率


从带有弧形玻璃外墙的心房到装有射流风机的停车场，从医院隔离室到洁净的制药房间；FloEFD的暖通空调模块和FloVENT提供了全方位满足建筑环境设计需求的CFD方案。

The recently released FloEFD HVAC Module brings a raft of features specifically tailored to enable FloEFD to be used for built environment simulations. FloEFD has an unrivalled pedigree in the automating of advance CFD (computational fluid dynamics) techniques and capabilities, allowing the user to focus on application and not numerics. This democratisation of CFD brings the ability to simulate the true 3D physics of air flow, contaminant dispersion, thermal comfort and thermal efficiency of the built environment to a much broader range of designers.
Occupant thermal comfort and the management of indoor air quality are key green building design challenges. Standards such as ASHRAE Standard 55-2004 (covering thermal comfort in a space) and ASHRAE Standard 62.1-2007 (covering ventilation for acceptable indoor air quality (IAQ)) can be addressed using CFD simulation. FloEFD’s HVAC Module provides the ability to simulate the following metrics, allowing spaces to be designed so as to assure acceptable thermal comfort behaviour and maximised IAQ levels:

[*]Predicted Mean Vote (PMV)
[*]Predicted Percent Dissatisfied (PPD)
[*]Operative (comfort) Temperature
[*]Draft Temperature
[*]Air Diffusion Performance Index (ADPI)
[*]Contaminant Removal Effectiveness (CRE)
[*]Local Air Quality Index (LAQI)
[*]Flow Angle
Radiative heat transfer is central to the thermal efficiency of any given built environment. Whether it is short wave solar loading or the effects of infrared radiative exchange, FloEFD’s advanced radiation capabilities allow for the modeling of:

[*]Semi-transparent solids (Radiation absorption in solids)
[*]Wavelength dependency
[*]Spectrum definition
[*]Specularity of surfaces
[*]Refractive index
From atria with curved glass facades to car parks with jet fans and from hospital isolation rooms to pharmaceutical clean rooms; FloEFD’s HVAC Module and FloVENT provide the full spectrum of CFD solutions for the needs of built environment design.
