Duct Checker Pro And this is the classic bedside software of engineers HVAC (Cold) This is a very powerful tool, and it's a very compact tool compute resistance, determine the dimensions of wind pipes, wind mouth (diffuser) and louver It's based on air flow.
Here's the details and how to make the most of this software for your job:
1. The core features of the Duct Checker Pro
The software is visually designed as functional tabs, which quickly solve ventilation system design problems and air conditioning:
- Tab Duct Size:
- Just type in airflow ($CMH$ or $CFM$).
- Select a pipe material (galvanized iron, concrete, fiberglass, etc.) to allow the software to calculate the friction coefficient automatically.
- The results will help you balance the size (Maxx Tall or circular diameter) of the pipe with the wind speed ($m / s$) and the pressure loss per meter of length ($Pa / m$).
- Tab Outlets:
- Supports rapid calculation of wind mouth size or number based on flow and wind outward velocity (to ensure no annoying noise in air conditioning space).
- Louvers Tab (Swindow Calculation):
- Determine the size of outdoor fresh or exhaust vent based on the free area to avoid leakage of rainwater or excessive wind resistance.
2. Why the Engineers HVAC You like the Duct Checker Pro?
Although there are tools like Daikin Duct Design or Mcquay Duct Sizer, the Duct Checker Pro still has a very strong standing due to its following advantages:
- Ultra light and convenient: The installer is only a few megabytes in size, and the interface displays all of the parameters on a flat screen, without having to open multiple complex submenu.
- Instant meals do not need complex settings: Many versions (such as the popular v4.01 version in Vietnam) are of the Portable - just unzip it and it'll run, no need for crack or copyright.
- Flexible unit conversions: Allows smooth back - and - forth switching between the metric system ($CMH$, $m / s$, $mm$) and the U.S./U.K. system ($CFM$, $FPM$, $inch$) – very convenient when working with different design standards (ASHRAE or TCVN).
3. Software-based basic wind tunnel calculation procedures
Typically, when designing a wind tunnel network, you will follow the steps in the Duct Checker Pro:
1.Select units and materials:Preparation.
Set the desired unit system (usually $CMH$ and $m/s$) , Select the pipe material to automatically apply the correct surface roughness
2. Input Parameters Input :Enter your data.
Enter the total flow of the section of pipe to be calculated ($Flow\ rate$) , Also enter one of two limiting parameters: Maximum wind speed ($Velocity$) or Limited pressure loss ($Friction$ – standard example would be $1\ Pa/m$)
3. Fix one edge of the wind tunnel:Space optimization.
Enter a side of the wind tunnel that matches the actual ceiling height of the structure (e.g., narrow ceiling fixes the height $H = 250mm$ or $300mm$).
4. Receive results and round numbers:Export your data.
The software will automatically calculate the remaining side size. You can simply circle this size according to the actual production module (e.g. $432mm$ results will circle $450mm$).
💡 Little practical tip: When calculating a building's ventilation system, to ensure that it runs smoothly (no aerodynamic noise), you should control the wind velocity ($Velocity$) in branches not exceeding $4 – 5\ m / s$, and in the spindle not exceeding $7 – 8\ m / s $.
