The module allows you to design a mechanical ventilation installation using systems based on ready-made sets of elements dedicated to residential buildings. The basic elements that can be used in the installation design are: rigid and flexible ventilation ducts, recuperator/air handling unit, ventilation manifolds, air intake, exhaust, supply and exhaust vents (ceiling, wall and floor), acoustic silencers and ducts insulation. For terminal elements, you can choose an ending (e.g. diffuser or ventilation grill). The installation plan is created on a plan view after loading an underlay (DWG, DXF, PDF, JPG, etc.) or after loading an architectural model of the building from an IFC file (requires access to an additional module in the Modules package – IFC (BIM) base import). When creating an installation plan, a 3D model of the installation is also created, which can be verified and corrected in the dedicated 3D View window. Calculation results can be analyzed directly in the drawings and model as well as in detailed result tables. Other chosen functionalities of the module:

  • Calculation of the required ventilation air flows in supply/exhaust vents based on two alternative methods (minimum multiplicity of exchanges nmin or values ​​of supply air flows Vsu and ehaust air flows Vex),
  • Determination of ventilation air flows in ducts, manifolds, recuperator, intake and exhaust,
  • Determining the air temperature in ducts (without taking into account temperature drp/rise on the route) to determine air parameters (density and viscosity, used in the calculation of pressure losses),
  • Diagnostics of exceeding the maximum air flow velocity vmax in ducts, supply/exhaust vents, intake and exhaust vents,
  • Diagnostics of obtaining the required minimum amount of fresh air per resident,
  • Calculations of linear pressure losses in rigid and flexible ducts,
  • Calculations of local pressure losses in manifolds, supply and exhaust vents, intake and exhaust vents,
  • Determining the required air flow and pressure in the installation for manual selection of a recuperator/ventilation unit with appropriate fan parameters from the selected manufacturer’s offer,
  • Automatic generation of a list of installation elements.
The module is under development and in each subsequent release the module will be supplemented with new elements and functions. We encourage you to submit your suggestions and comments to info@instalsoft.com. The dates of the next releases of the InstalSystem 5 package can be found here.
