DD4M Air Duct Design

DD4M Air Duct Design logo.

Uses ASHRAE equal friction, constant velocity and / or static regain procedures to design air ducts for air conditioning, heating, ventilation and materials handling. Allows 1000 duct sections and paths in any configuration. Handles rectangular, oval or round ducts in the same system. Recommends duct sizes, allows override if desired. Pop-up screens for automated inputs of 100+ ASHRAE fittings. Modern screens with windows, prompted inputs, pop-up calculator, defaults, error checking, "help" messages at every input field.
