[edit] Merge

A vapor-compression refrigeration system and a phase-change heat pump seem to be the same thing; the article on vapor-compression refrigeration even states, "a vapor-compression refrigeration system may sometimes be referred to as a phase change heat pump," which indicates we don't need an article for each. The same suggestion to merge has been made on the talk page for the phase change heat pump article. Tobinmarcus 16:01, 6 July 2006 (UTC)

Tobinmarcus, I strongly disagree with merging the two articles. Yes, vapor-compression refrigeration and a heat pump are simply two sides of the same thermodynamic cycle. However, refrigeration and heat pumps are, in the common and widely accepted usage, two distinctly separate techniques. The articles have been written for a wide range or readers ... and not just for thermodynamic purists (not to say that that was your motivation). This article's inclusion of the statement "a vapor-compression refrigeration system may sometimes be referred to as a phase change heat pump" is simply for the purpose of explaining that there are other names for vapor-compression refrigeration ... it is not a reason for merging. . Again, I strongly believe they should remain as separate articles and therefore I am going to take the bold action of removing the merge tag. - mbeychok 18:37, 6 July 2006 (UTC)
I agree that heat pumps and this article should not be merged. However, Phase change heat pump should be merged into this VC article, but maybe with some content going to heat pumps. The phase-change heat pump's figure is colorful and might make a nice intro to this article, but I do have a problem with the blue 'coolth' arrow shown on it ... 129.237.114.171 21:41, 8 November 2006 (UTC)
I disagree that Phase change heat pump sould be merged with this article. Phase change heat pumps (with reversing valves so that they can function as air coolers or as air heaters) are, to a large extent, primarily used in HVAC applications in residential homes and other buildings. On the other hand, vapor-compression refrigeration is very widely used in large-scale industrial processes as well as in air conditioning and I strongly believe it deserves to be a stand-alone article. As for the image in the Phase change heat pump article, it is indeed colorful but it also simplistic. It is a nice "logo" type image but it does'nt adequately depict the vapor-compression system. In my opinion, it would be much better to merge Heat pump and Phase change heat pump. mbeychok 23:19, 8 November 2006 (UTC)

[edit] Ozone depletion

The "Disadvantages" heading states that many vapor-compression refrigeration systems are "still" using HFCs (true) and that HFCs contribute to ozone depletion (huh?). The point of switching to HFC refrigerants (like R-134a and R-410A) is that they don't contain chlorine. By my understanding, it's only chlorine and bromine that affect the ozone layer. According to the article on ozone depletion, fluorine reacts with water so quickly that its effect on the ozone layer is trivial. Was HCFC meant here instead?

Mind you, the entire haloalkane family has massive Global warming potential compared to CO2. But that's a separate problem. Chronos Tachyon 12:58, 26 May 2007 (UTC)

Chronos Tachyon, if you believe that the change should be made, then be bold and make the change in the article. - mbeychok 15:54, 26 May 2007 (UTC)
Done. I think whoever wrote that section got confused by the Coca-Cola press release, which was talking about global warming and not ozone depletion. Chronos Tachyon 05:15, 9 June 2007 (UTC)

[edit] Minor Change

I added HVAC to the "see also" section, and alphabetized the list johntindale 20:06, 6 June 2007 (UTC)

[edit] 3rd world

R12 never took over in the 3rd world like they did here, highly flammable hydrocarbon gases have long been the standard refrigerant, butane, propane etc. Article seems to ignore this at the mo. Tabby (talk) 04:45, 6 January 2008 (UTC)
