可变风量（VAV） 3D模型

Variable Air Volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant temperature. The advantages of VAV systems over constant-volume systems include more precise temperature control, reduced compressor wear, lower energy consumption by system fans, less fan noise, and additional passive dehumidification. 3D DESCRIPTION -Model is created in 3dsmax2009 Rendered with Vray - Materials included -Polygonal geometry (quad/tris) -All vray material are included Model is highly detailed and is suitable for close-up You can create a larger composition Fully detailed, textured model. Detailed enough for close-up renders. Comes with detailed normal materials, This set will allow you to collect the ventilation system of any complexity in a few minutes. Originally modeled in 3ds Max 2009. Final images rendered with V-Ray. The 3ds Max zip file contains also V-Ray and standard materials scenes. - Easy to convert model in other formats. - No need for any special plug-in to open the model. - Useful for BMS, BAS, high resolution renders, magazines and production. - No multi/Sub-Objects materials. - Materials, textures and objects are clearly named. - Export formats works correctly
