72. Free Download CAD Drawings of HVAC Systems – Ventilation, Gas, and Central Control

This CAD drawing set presents the schematic diagrams of three essential HVAC systems in a building: ventilation, gas piping, and control wiring. The ventilation layout shows the placement of fresh air supply fans, exhaust fans, and ductwork connecting key spaces such as the bar, kitchen, dining room, restrooms, and technical rooms. The gas piping schematic illustrates the centralized fuel distribution network, with tanks, pipelines, branch connections, safety valves, and supply routes to kitchens, restaurants, and functional areas. The control wiring diagram highlights the Intelligent Touch Manager, ensuring centralized monitoring of air conditioning units, sensors, and airflow systems. Together, these schematics guarantee clean air circulation, safe fuel supply, efficient energy management, and modern building operation. These CAD drawings are an integral part of the HVAC design documentation, supporting architects, engineers, and contractors in creating safe, comfortable, and energy-efficient environments.
