G'day Peter

Somewhere on this site Marc Obrien posted a link on a ductulator he had designed.

If you can find it check it out.

You can also look through the Trane book store for educational material you can purchase over the net.

I have some of these and they are well worth the small amount money you will pay for them.

You're nothing with a calculator if you don't know how to input everything and make a judgement of the results if they're somewhat in the expected region.

Exactly right.... I completely agree.

Using calculators/software programs is the absolute worse thing anyone can do, if they do not know what the results mean.

Programs can be dangerous, since you input data, and get data out. You need to know what the output data means, AND, if the output data is correct (or close enough).

Programs & calculators should only be used by someone who understands the process, whether it is pipe sizing, duct sizing, or selecting compressors.

Excuse me chaps, i was under the impression the fella was asking for information on designing simple duct systems? NOT asking for a magical calculator.

I highly recommend obtaining a design manual from either Trane or Carrier for this. If you have not done this before, it would be prudent to have a qualified person review the selections and layout.

An ounce of prevention, is by far cheaper than saving a few dollars, pounds, euros or quid.

Hi botrous,

..we already discussed that and you know that I do agree with you completlyyyyyy

I know.... We did discuss this before. I could not help but to reinforce Peter_1's comments. Using a program can create more problems than those solved.

Absolutly right
