Ventilation equipment selection software

Ventilation equipment selection software

November 9, 2021

Whether we are talking about apartments and offices or factories and warehouse complexes, where the most complex of engineering solutions are often found, high-quality ventilation is necessary not only for the well-being and overall mood of the staff but also for the safety of goods.

By order of the largest manufacturer and importer of climate equipment in Europe and the CIS, Rusklimat Holdings, a “Ventilation Equipment Selection Program” (VESP) was created for the design and sale of ventilation equipment.

VESP includes a server and a web application for calculating operating modes and selecting the most suitable component sizes when planning for ventilation systems. The installation scheme compiled by the user in addition to the initial data on the equipment's series, the operating modes of the installation, as well as the individual components used. Now the program calculates for more than 10,000 ventilation units every month.

Project management

Existing calculations can be moved or copied over to an arbitrary project.

List of project calculations

Calculation creation

Calculations are created using the visual configurator by placing the components of the ventilation system in certain places. The layout is finalised by dragging certain elements into the configurator's workspace.

Available components:

  • Water heater;
  • Electric heater;
  • Water cooler;
  • Freon cooler;
  • Plate recuperator;
  • Rotary recuperator;
  • Glycol recuperator;
  • Air valve;
  • Air filter;
  • Flexible insert;
  • Fan;
  • Silencer;
  • Spray-type or surface humidifier section;
  • Uni and bi-level mixing sections;
  • Empty section;
  • Elements of the ventilation system’s automatic control.

It is also possible to select components for automation:

  • Control cabinets;
  • Frequency converters and regulators;
  • Pressure sensors and relays.

The input of initial data

The following parameters are specified:

  • The type of installation;
  • Air consumption;
  • The availability of additional options;
  • An array of source data for each component (the number of parameters varies from 1–2 to 10–15).

Calculation of input, extract or input-extract installations

Installations of two subtypes are implemented:

  • Frame-panel, consisting of 4 series of equipment (each series of equipment in a general industrial or explosion-proof design);
  • Modular, consisting of 2 series of equipment.

The calculation and selection of installation components

  • Selection of installation components for the task conditions;
  • Calculation of the operating modes of the components;
  • Calculation of the cost of components;
  • Calculation and selection of control automation;
  • Calculation of the cost of the frame;
  • Determination of the cost of assembly in man-hours and capital;
  • Construction of a schematic drawing.

Calculation log

The calculation logs are displayed on the screen to identify incompatibilities, or to adjust the input data for recalculation.

Comparison of options

It is possible to simultaneously calculate the installation of different standard sizes. This will enable subsequent comparisons with cost or performance as the variables.

The algorithm for planning automation

One of the most difficult tasks was the creation of an algorithm that would select the level of automatic control for each ventilation system. Automation consists of the following elements:

  • A control cabinet with a set of options;
  • Additional options for control cabinets;
  • Regulators;
  • Sensors.

Subtleties of calculation

  • Control cabinets can be of two different series, each with its own sets of options.
  • A special selection algorithm is implemented for each cabinet series.
  • The composition and design modes of the installation are analysed. After that, the most suitable ready-made cabinet is selected, with the minimum possible set of options necessary for ventilation control.
  • The directory of cabinets with their characteristics and options may be expanded by adding new cabinets.
  • At the final stage of cabinet selection, the following are added:
    • Additional options not included in the finished cabinet;
    • Regulators and sensors.
  • The ability to combine several components into a single section to reduce the cost of the frame. Usually, each component corresponds to its own section.

Results exporting

  • The downloading of technical specifications for engineers: equipment specifications, calculation results, drawings, etc.
  • The exporting of commercial offers for customers in Excel, PDF or JSON formats, all automatically sent to 1C.
  • The exporting of the installation drawings for designers in DFX format for AutoCAD.
  • The exporting of 3D installation drawings to the Autodesk Revit integration plugin.

  • System directories: companies, users, roles, access rights, currencies, settings for integration with 1C.
  • Component directories: names, product codes, prices and characteristics.
  • Calculation settings: calculation constants and cost constants.

Differentiation of access rights

  • The main administrator has unlimited access.
  • The company administrator has full access within the organization.
  • Managers are able to create calculations and commercial offers.
  • Engineers create and modify calculations.

Syncing with 1C

  • Creating VESP projects from the 1C interface with the assignment of a unique identifier.
  • Synchronization of prices and exchange rates.
  • Loading new components and updating existing ones for ventilation systems.
  • Synchronization of the composition of the commercial offer.

OEM versions

Support for OEM versions of the VESP, with the possibility of marketing adaptation to an OEM partner:

  • Names of components of ventilation systems;
  • Images of components for the configurator in addition to schematic drawings;
