Accessing Tools
Section titled “Accessing Tools”Psych Chart and Ductulator are items in the main sidebar — click either one directly, there’s no separate “Tools” menu to open first.
Both are also listed under Navigation in the command menu, which the Search button (Cmd/Ctrl + K) opens from the home sidebar and from inside a project.
Both tools also have direct URLs:
- app.hvakr.com/tools/psychrometric-chart
- app.hvakr.com/tools/ductulator
No project is required to use them, but you do need to be signed in to an HVAKR account with an active subscription.
Tool Features
Section titled “Tool Features”Interactive Interface
Section titled “Interactive Interface”- Psychrometric Chart — click or drag to place and move state points, with real-time property calculations
- Ductulator — enter your design constraints and the sizing result updates when you commit a field: press
Enter, click out of it, or use its stepper arrows
Unit Conversion
Section titled “Unit Conversion”Both tools follow the Default Units preference under Settings > Preferences (Imperial or Metric) and convert values automatically.
Saving Your Work
Section titled “Saving Your Work”- Psychrometric Chart — Save stores the chart under a name; the History sidebar lists your saved charts to reopen, rename, or delete. The copy control on the chart puts a PNG of it on your clipboard
- Ductulator — recalculates from your inputs; there’s no save or history, but any overridden dimension can be reset back to the calculated value
Standalone by Design
Section titled “Standalone by Design”Psych Chart and Ductulator always run independently of project data — they don’t read from or write to a project, and nothing you do in them changes a project. You can reach either one from inside a project with the command menu, but opening it leaves the project view. Use them for quick reference calculations alongside your project work, not as part of the project workflow itself.
Best Practices
Section titled “Best Practices”- Use for verification - Double-check automated calculations
- Explore scenarios - Try different conditions
- Learn the physics - Understand what’s happening
- Save chart configurations - The Psychrometric Chart’s saved history makes it easy to revisit past scenarios
