HVAC Load Calculation Extension For AutoCAD MEP and Revit MEP

The HVAC Load Calculation Extension by Autodesk, Inc. is a commercial and industrialized HVAC (Heating, Ventilation, and Air Conditioning) alluviation computing software package whose calculations are supported upon the ASHRAE 2005 Fundamentals radiant instance series (RTS) method. The determine of this software is to wage you with total chilling and vaporisation loads for a antiquity so that you haw right specify the correct filler HVAC equipment (whether it is a packaged rooftop unit or a boiler). This information is intermeshed specifically toward the HVAC engineer, architect, design/build machinelike contractor, and antiquity fix supervisor.

The HVAC Load Calculation Extension is acquirable to customers of AutoCAD MEP 2009 and AutoCAD Revit MEP Suite 2009 on Autodesk Subscription and is person to Autodesk Subscription terms and conditions.

The Extension supports sustainable organisation by allowing engineers to right filler HVAC equipment without oversizing. Conventional good dictates that it is meliorate to hit likewise much chilling than not enough. Without the knowledge or tools to accurately intend vaporisation and chilling loads, oversizing equipment is a ordinary practice. However, oversized equipment wastes a tremendous turn of forcefulness throughout its lifetime. In a BIM-supported workflow, psychotherapy capabilities and computing tools (such as this Extension) enables designers and engineers to more good investigate organisation alternatives and optimize their aborning organisation for forcefulness efficiency and sustainability.

The HVAC Load Calculation Extension uses formulas from the ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Handbook of Fundamentals. This publication compiles the fundamentals of the HVAC, much as methods for conniving extreme chilling and vaporisation loads for buildings.

The Extension produces a sort of reports including: a unofficial alluviation perturbation by individualist room; a detailed alluviation perturbation by individualist alluviation components much as roofs, walls, people, and lighting; and a psychrometric inform that includes the properties of the entering and exiting air. Some of these reports allow graphs for meliorate image of the alluviation breakdowns. Users also hit the knowledge to export bespoken reports to Microsoft Word or Excel applications.

The Extension is able to import antiquity information from AutoCAD MEP or Revit MEP using the gbXML file format. This effectuation that every pertinent information most the antiquity crapper be transferred to the Extension so that rattling little drill accumulation entry is needed. Once the chilling and vaporisation alluviation calculations are performed, the results crapper be exported backwards to AutoCAD MEP or Revit MEP for proper funiculus and tube sizing.
The HVAC Load Calculation Extension includes the mass basic features:
  1. Inputs for HVAC system characteristics much as cater chilling and vaporisation temperatures, word rates, fan characteristics, chilling and vaporisation setpoints, funiculus sizing, and safety factors
  2. Inputs for HVAC Atlantic (room) characteristics much as wall, window, roof, door, skylight, and construction areas. In addition, there are inputs for # of people, electrical appliances, infiltration, lighting, miscellaneous, exhaust, and plenum loads
  3. Weather accumulation from over 800 cities throughout the world
  4. A rank u-value database for ordinary wall, roof, window, floor, and entranceway types
  5. A rank contrivance itemize for determining interior electrical equipment alluviation contributions
  6. Many reports including summary, detailed, psychrometric, wall/window breakdown, 24-hour alluviation breakdown, and graphical reports
  7. A feature that allows the user to export every inputs and outputs to bespoken Microsoft Word and Excel documents
  8. Equipment selection
  9. Support for both arts (IP) and Metric (SI) units
