How a refrigerator works

Please improve this. I am trying to find out how a fridge works and this has confused me even more. For example 'saturated liquid refrigerant', what is it saturated with? Can we have some boiling points for the refrigerant and figures for the pressures please, so that we know the pressure of the superheated vapour, and the flash pressures? What about telling us where the parts are relative to each other, eg compressor, condenser, coils etc; a diagram would be helpful. 25 Oct 06

Commerical Freezers?

I read somewhere that there was a standard for a super-freezer, for food service use. Something that prevented bacteria growth in raw fish, etc. Regular consumer fridges reach like -30, but this was far colder (-60?) and used not only for Sushi stuff, but flash-freezing raw produce? Details are lacking, and I don't find it on this page, so I'm wondering if I saw it in a prior revision and I'm wondering if the deletionists got to the information (ie: does anyone have an application that will search the old versions of wikipedia articles?)

Refrigerator Reliability

Refrigerators in our days becoming more and more advanced, with a lot of sensors, control boards, interface boards, etc. Manufacturers are trying to make them be more Energy Efficient. But at the same time, reliability is got worse. You were able to troubleshoot and if needed replace the problematic mechanical thermostat on the old refrigerator. Today, everything relies on the control board and sensors. If the control board will fail, nothing going to work. To troubleshoot a complicated control board, you have to have some electrical skills and knowledge. Not as with a simple mechanical thermostat. Where a majority of DIY'ers were able to fix or replace refrigerator thermostats.

Auto-Defrosting

This info needs to be corrected because there are some misinformation provided in the text "Frost-free refrigerators, including some early frost free refrigerator/freezers that used a cold plate (this type of refrigerators with cold plate never had an auto-defrost feature) in their refrigerator section instead of airflow from the freezer section, generally don't shut off their refrigerator fans during defrosting (this is not true. compressor and fans need to be off in order to perform defrost cycle). This allows consumers to leave food in the main refrigerator compartment uncovered, and also helps keep vegetables moist. This method also helps reduce energy consumption, because the refrigerator is above freeze point and can pass the warmer-than-freezing air through the evaporator or cold plate to aid the defrosting cycle."

Edward Toussaint's invention/patent of an absorption refrigeration system unsourced?

Should the article'sstatement that Edward Toussaint invented the first absorption refrigeration system in 1859 and patented in 1860 be edited if not removed? The claim is unsourced, and the only statement to that effect outside of Wikipedia that I can find in an initial search with Google and Google books is a brief statement in a search result for an article requiring a subscription to read in full, and may well be based on this very article. This seems like a significant claim to be overlooked in accounts of the history of refrigeration.

Worse, even if the claim that this person invented and patented an absorption refrigeration system, the claim that he was the first to patent an absorption machine using water and ammonia is absolutely false. Ferdinand Carre patented his first continuous absorption machine using water and ammonia in 1859, and his first intermittent adsorption machine using same obviously came before that. So at the very least, that part of the article should be heavily edited, and both Ferdinand Carre and Carre's priority on this system of refrigeration should be added. 67.168.191.4 (talk) 17:32, 15 April 2024 (UTC)

There's this source; though it's marked "Opinion," the part about Toussant is background, so it may be acceptable in this context. Strangely, Ferdinand_Carré is only mentioned in an image caption in the current article, so it seems reasonable to expand on his contributions in the text.

Yes - agreed on expanding on Carre's role in the text.

Hmm - looking at the relevant passage in your linked source, I do believe that is the same as the one I was seeing in my Google search results that kept turning out to require a subscription to read. Interesting.

So we seem to have a reference in a single article appearing in multiple publications, and a statement with no marked reference in the Wikipedia article, concerning what would seem to be an at least noteworthy inventor in the history of refrigeration; I feel like there's a mystery here that needs solving. Why are reference and sources concerning a French inventor patenting and marketing an ammonia based absorption system at virtually the same time as - though starting a bit later than - Ferdinand Carre be so difficult to find. I'm baffled. 2601:603:4E82:7C20:CE9A:9A0A:F6DB:AD17 (talk) 06:40, 16 April 2024 (UTC)

It's possible that the references on Toussaint are circular, though I doubt it's an outright fabrication as are some of these examples. It's not really an extraordinary claim (e.g., that Toussaint was the definitive inventor of refrigeration); feel free to expand on Carre's role in the body of the article as you see fit. As to why better sources are hard to find, this kind of material of often found in printed materials that do not easily surface in web searches. OhNoitsJamie ^Talk 13:38, 16 April 2024 (UTC)
