Calculation and design programs for natural, supply and exhaust ventilation systems

To help the engineers involved in the design and calculation of ventilation, many programs have been created. The computer will not only calculate all the required parameters, but also make ventilation drawings. Read about the most convenient and simple solutions, as well as on what the algorithm of their work is based on.

Vent-Calc ventilation calculation software

Ventcalc
Ventcalc

Vent-Calc design software is one of the most functional and affordable. The algorithm of her work is based on Altshul's formulas. Hydraulic calculations of the air ducts are done according to the technique taken from the “Designer Guide” edited by Staroverov. It copes equally well with the calculation of natural and forced ventilation.

Program Functions for Ventilation Vent-calc:

  • Calculation of air ducts taking into account the temperature and speed of the flow, air flow;
  • Calculation of air ducts hydraulic;
  • Calculation of local resistances (narrowing, bends, extensions and forks) of the channels of the premises. Resistance coefficients are calculated on various parts of the system, pressure losses in Pascals, the program selects ventilation equipment. To make sure that the calculations are correct, tables BCH 353-86 are attached. During operation, the ventilation program sends the user to the required formulas and tables;
  • Suitable for calculating natural ventilation. The optimal section of the ventilation duct is determined, ensuring thrust prevails over air resistance at a given air flow;
  • Counts the heating power with a heater or any other type of air heater.

This program for calculating ventilation systems is very good for students who are just taking a ventilation course at the university. Another advantage is its free distribution.

Manual calculations have long been abandoned
Manual calculations have long been abandoned

The latest edition of the Vent-Calc ventilation design program allows you to calculate the aerodynamic drag of the system and other parameters necessary for the preliminary selection of equipment in the shortest possible time. This requires the following indicators:

  • length of the main duct of the room;
  • air flow at the beginning of the system;
  • air flow at the end of the system.

Manually, such a calculation is quite laborious and is carried out in stages. Therefore, the program for calculating Vent-Calc will facilitate and accelerate the work of designers, specialists in the sale of climate control equipment and qualified installers.

Program for designing engineering systems MagiCAD

Magicad
Magicad

This is a program for the design of ventilation, heating, water supply and sanitation, electrical networks. MagiCAD calculates and makes the necessary drawings.

It will be useful for builders, designers, draftsmen and equipment sales managers.

MagiCAD Features:

  • all types of calculations for ventilation systems (supply and exhaust);
  • 2D image;
  • 3D image
  • the widest database of equipment of European manufacturers;
  • creation of all necessary project documentation, including specifications;
  • the ability to exchange data with other programs for drawing ventilation;
  • Compatible with ADT and AutoCAD.

MagiCAD graphics is based on AutoCAD and is actually a complement to it. The program was created by Finnish developers who have simplified its use as much as possible.Therefore, an engineer familiar with AutoCAD can easily figure out a subsidiary program for calculating ventilation and other MagiCAD engineering systems. Ease of use is achieved by dividing the core into modules: Ventilation, Pipelines, Electricity and Premises.

The specialist does not need to draw complex air distribution networks, fittings and turns. Ready-made elements are made up like a constructor. Not even a ruler is needed. The main work of the designer is to correctly assemble the existing nodes to obtain the optimal result. All data about the project is present right there. Having looked in the electronic drawing, you can get the necessary information about the operation of future ventilation, for example, about the cross section of the air ducts and the air flow rate in them.

The program for calculating ventilation systems MagiCAD is used by dozens of large design bureaus of the Scandinavian countries and many design organizations of the CIS countries.

GIDRV 3.093 natural ventilation and aspiration calculation program

Gidrv
Gidrv

The GIDRV 3.093 program is designed to calculate forced and natural draft ventilation systems. It is a multi-tasking form with a set of bookmarks: “Scheme Characteristics”, “Floors”, “Plots”, “Local Resistance”, “Calculation Table”.

Functions of the program for calculating natural ventilation GIDRV 3.093:

  • control calculation of the parameters of the exhaust duct of natural ventilation;
  • calculation of a new and control calculation of air channels for aspiration;
  • calculation of new and control calculations of supply and exhaust ducts for systems with forced draft.

Having obtained the results, you can change the initial parameters on any sections of the ducts and make a new scheme. Using this program for calculating natural ventilation, you can select any combination, achieving optimal performance.

Schemes with explanations (channel characteristics, system impedances, calculation results) are stored in a single file. Switching and working with various calculation options are very convenient and simple.

Areas with excessive pressure are automatically detected and options for solving the problem are provided (to narrow the cross-section, use diaphragms, gates, throttles).

The calculation program for natural ventilation is equipped with a function for calculating throttling mechanisms, which gives out several best options and identifies the most suitable one.

In the process of calculating natural ventilation, it detects the most congested parts of the system. Shows the pressure for each section, losses and their causes (pipe resistance, friction).

All calculations can be printed, including tables.

Paid, but a demo version is available for review.

Fans 400 smoke ventilation calculation program

fans 400

The Fans 400 program is designed to calculate smoke ventilation. With its help, you can determine the performance of the smoke removal system from the halls, corridors and vestibules. The program for calculating smoke ventilation helps to choose the power of fans and other special equipment.

Fans 400 was created for design engineers, fire inspectors and students of specialized specialties.

The use of anti-smoke ventilation for calculations will not cause difficulties for a user of any level of training. It is distributed free of charge. For the program to work correctly, a printer must be connected to the computer.

Ducter 2.5 Duct Selection Program

Ducter 2.5
Ducter 2.5

This ventilation equipment selection program calculates duct diameters. The user enters the maximum values ​​of the flow velocity in the ducts, elevation differences in the calculation of natural ventilation or KMS section. Based on this information, the program selects ventilation equipment of standard diameter according to VSN 353-86 linearly. Thus, the final decision on the diameter remains with the specialist.

If you need an air duct of non-standard parameters, the program will also help: one parameter is entered, the rest are selected. The selection step is set in the settings.

Pressure and temperature indicators are set if the air conditioning system is being calculated. It is possible to obtain pressure data for each section by entering its length and total resistance coefficient. The material of the future duct is taken into account.

You can specify one of several options for displaying the size of each plot.

Version of the program from Ducter 3 and above for the selection of equipment will help to fully calculate the entire ventilation system.
