Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based HVAC chart for plotting air states, mixing air streams, and working through cooling calculations, alongside a broad set of HVAC calculators.

Landing page captured for the 2026-11-04 issue.

For: HVAC technicians and engineers working with air properties
Worth noticing: Mixing uses dry-air-mass weighting derived from inlet volume flow and specific volume; the page flags fog-forming mixtures.

Field notes

The interface includes controls for moving or removing points, undoing a clear, and labeling a selected air state. Its notes distinguish quantities reported per mass of dry air from moist-air density, and specify that below-freezing dew point is reported over ice. The tool list also includes a Ductulator, refrigerant references, and separate calculators for fan laws and chilled-water flow.
