T20 Tianzheng HVAC V7.0 Official Release with Installation and Setup Guides, Compatible with CAD 2010-2021

T20 Tianzheng HVAC Software V7.0 supports Win7 32-bit AutoCAD 2010-2016 and Win7/10 64-bit AutoCAD 2010-2021 platforms, making it a powerful, specialized, and intelligent HVAC design tool. The software complies with key standards such as “Heating, Ventilation, and Air Conditioning for Civil Buildings GB50736-2012,” “Technical Standard for Building Smoke Control and Exhaust Systems GB 51251-2017,” and “Code for Fire Protection Design of Garage, Repair Shop, and Parking Lot GB 50067-2014.”

Featuring intelligent custom entity technology, pipelines and equipment automatically manage their interrelationships. Tianzheng objects support double-click editing for quick modifications. The software covers a wide range of HVAC specialties, including heating, ventilation, air conditioning, and multi-split design. It enables rapid floor plan layouts, automatic system diagram generation, and comprehensive material statistics.

With powerful calculation modules, designers can easily perform various computations and export calculation sheets, allowing them to focus more on engineering innovation. While efficiently generating 2D drawings, the 3D view synchronizes in real-time, enabling quick transitions from 2D plans to 3D models for clear project overviews. Changes made in the 3D view automatically update other views simultaneously.
