[edit] To-Do Lists for HVAC Article

[edit] Main To-Do List

If you have a suggestion of how someone with expert knowledge of HVAC systems could improve this article, put it here. This section is not the place for questions or comments, please put them in one of the other sections on this page, or make your own section. When an item on this list is completed, please move it to the "Completed To-Do Items List," if you think people could benefit from seeing it on the talk page, or just delete it completely.
Also, when creating a new thread- please start at the top of this page after the horizontal line, so that newest threads are always at the top. Posts prior to 2008 are now in the Talk:HVAC:Archive1 johntindale (talk) 13:53, 14 May 2008 (UTC)

[edit] More Page edits and cleanup

As you can see, There is an archive. Talk:HVAC:Archive1 This archive contains everything prior to 2007. The talk page was getting a little difficult to navigate. Second, I created an introduction for Energy Efficiency, and sorted the following paragraph so that it flowed with the order of the main page. johntindale (talk) 14:42, 14 May 2008 (UTC)

[edit] Update

It looks like it has been a while since anyone has addressed some of the issues and suggestions made in this talk section, so maybe we should clean it up a bit? I suggest creating a "talk archive" at the bottom of this page, and move some sections to it such as; questions and answers, completed to-do items, and other items that inhibit flow and are valid, but tend to clutter the page. I'll wait for suggestions, and begin moving some things gradually depending on input from other participants. --johntindale (talk) 22:10, 9 May 2008 (UTC)

How about simply archiving the stuff? Pzavon (talk) 15:03, 10 May 2008 (UTC)

That's a good idea #REDIRECT Talk:HVAC:Archive1 johntindale (talk) 13:38, 14 May 2008 (UTC)


[edit] Delete External Links Section?

Looks like there are repeated problems with commercial links being added. Deleting the entire external links section (without embedding links elsewhere in the article) unfortunately would likely be the most effective method of reducing the added spam. What do you think?

[edit] Second paragraph

The second paragraph sounds like a brochure more than an encyclopedia. Here it is, for your review:

"The HVAC industry is huge, worldwide, with career opportunities ranging from operation and maintenance, to system design and construction, to equipment manufacturing and sales, and to education and research. Annual sales are in the US$100's of billions. There are also hundreds of related local, national, and international professional, technical, trade, and labor organizations such as ASHRAE, SMACNA, ACCA, and AMCA, to name just a few, that support the industry and encourage high standards and achievement."

[edit] Page Edits

14:06, 22 April 2007 (UTC) I made some edits to the whole page to make each paragraph contain its own central idea or concept
 (some paragraphs ran together) I also added some definitions, and several paragraphs
 to entries to try to explain a few complex concepts a little more clearly and concisely. Johntindale

--johntindale 15:19, 8 May 2007 (UTC) I added definitions to complete the following from the To-do list: There where several terms in the "Major Terms" section that where not defined in the HVAC article, and that I could not find an article for elsewhere.

List of terms:

  1. once-through
  2. low-flow
  3. primary-secondary

I cannot create these articles because I do not what these terms mean.

Please either create articles for these terms, or define them within the HVAC article itself, and remove the links I created (instead of using links, just make the terms bold: once-through instead of once-through).

When you have completed this task, please remove this from the To-Do list.

[edit] What is the / Is there a technical definition of Fan Powered Box?

Is this just regional terminology for a fan coil unit, or is it a separate category of equipment? And if it's its own thing, how is it defined? This is (obviously) a question from someone not very familiar with the field. Great page, though. Very informative and not overly technical. This is why I love Wikipedia. 69.25.215.134 21:18, 22 June 2007 (UTC)

A fan powered box is simply a cabinet with a fan in it. Because there are so many applications in HVAC that use cabinet- mounted fans, sometimes generic terms are used to describe them all.johntindale (talk) 14:12, 14 May 2008 (UTC)

[edit] Minor problem

The first paragraph of the heating section ends in an incomplete sentence. Please fix. --Cromwellt|talk|contribs 22:25, 1 July 2007 (UTC)

This issue has apparently been resolved.johntindale (talk) 14:35, 14 May 2008 (UTC)

[edit] "...Special refrigerants called Freon, a member of the CFC family."

Partially true. It should read as "special chemicals called refrigerants." Freon is a company name. Freon makes / made CFC's, HCFC's, HFC's etc. Refrigerants are bought and sold as R-(number) not F-(number). —Preceding unsigned comment added by 206.47.38.3 (talk) 20:02, 11 October 2007 (UTC)

[edit] Aitch-vac?

I can see how this is trying to explain that some people pronounce it "H-vac," but as an American speaker of English, I can't see "aitch" being pronounced as "H." The dipthong "ai" might occasionally be pronounced like that (like in "pain",) but at the start of a word I can't see it as anything other than a long "I" sound. I suspect other English-speaking countries would read that in different ways, too.

Wouldn't it work to just say that it's also pronounced "H-Vac"? Or use the phonetic alphabet.192.174.37.50 (talk) 23:17, 28 November 2007 (UTC)

[edit] Re: HVAC Systems Design and Safety

In the 2008 Nanotech/Cleantech forum sponsored by the California Institute of Nanotechnology and the Cleantech Institute, a new type of HVAC system was unveiled by Blue Earth Energy Systems using liquid nitrogen as a coolant and combining a traditional system with a Rankine cycle turbine. The resulting system reportedly uses only 13% as much energy as a conventional HVAC chiller.[1]

This is nothing but advertising, and it certainly has nothing to do with the headline. And an internet search for "Blue Earth Energy Systems" turns up a webpage looking suspiciously like vaporware.--Komodon (talk) 05:24, 26 February 2008 (UTC)
