HVAC Design & Drafting Course

HVAC Design & Drafting refers to the process of designing and creating detailed plans for heating, ventilation, and air conditioning (HVAC) systems within buildings. It involves selecting the appropriate systems for the building's needs and creating precise technical drawings and specifications for installation.

HVAC Design & Drafting

Key Elements of HVAC Design & Drafting:

  • Load Calculations:
    • Heating and cooling load calculations based on building size, insulation, local climate, and occupancy.
    • Manual J Calculation – A standard method for determining the appropriate HVAC system size for energy efficiency and comfort.
  • System Selection:
    • Cooling Systems: Chillers, air conditioners, rooftop units, and split systems.
    • Heating Systems: Boilers, furnaces, heat pumps, and electric heaters.
    • Ventilation Systems: Exhaust fans, fresh air systems, and air quality control equipment.
  • Ductwork Design:
    • Duct Sizing – Optimized for airflow efficiency and energy conservation.
    • Duct Layouts – Designed to minimize noise and air travel distance.
  • Piping and Refrigerant Lines: Specification of piping for water-based systems and refrigerant lines for air conditioning.
  • Ventilation and Air Distribution:
    • Balanced airflow distribution throughout the building.
    • Design of supply and return air ducts, diffusers, grills, and registers.
  • Control Systems:
    • HVAC control components like thermostats, dampers, valves, and sensors.
    • Building Management Systems (BMS) for monitoring and optimizing HVAC operations.
  • Energy Efficiency Considerations:
    • Selection of energy-efficient HVAC equipment.
    • Integration of sustainable and green-building principles.

Software Used in HVAC Design & Drafting:

  • AutoCAD – For 2D and 3D HVAC layouts.
  • Revit – For Building Information Modeling (BIM).
  • Trane Trace 700 – For load calculations and energy simulations.
  • Carrier HAP – For energy and load analysis.
  • Ductulator – For quick duct sizing.

Career Opportunities in HVAC Design & Drafting:

  • HVAC Design Engineer – Responsible for system calculations, design, and selection.
  • HVAC Draftsman – Specializes in creating detailed technical drawings.
  • BIM Specialist – Works with 3D modeling for HVAC integration in buildings.

Training and Certifications:

  • HVAC Design Training – Available through ASHRAE, Coursera, LinkedIn Learning, and Udemy.
  • Autodesk Certified Professional – Certification in AutoCAD and Revit.
  • ASHRAE Certifications – Specialized training in HVAC design and energy efficiency.
