Abstract
Computer aided design was used to design a ventilation system in an example problem. The design methodology used in the program described reduces all the elements of the system to equivalent feet of straight duct and is referred to an the equivalent foot method. The author states that this system generates a better design than the comparable blast gate method. Step by step instructions for using a ventilation design program were provided, with a discussion of each step. The design of a ventilation system was said to begin with the preparation of a carefully labeled schematic drawing. The ventilation design program is then loaded into the computer, and the user indicates whether the system is in an existing file. The function of each of the options on the display menu were self explanatory; however, each option was demonstrated in the example design. The options included deleting, renaming, or duplicating a branch, determining pressure losses or gains, balancing branches at a junction, determining a fan's static pressure loss, listing branches and their losses, calculating the pressures to a point, calculating velocity of air for a certain duct size, and several others. A sample printout of the program results were provided so that the user could follow the instructions and compare his results to the author's.
