Keep it on ice

Haha, toxic chemicals. I think I'll just stick with the icebox, thanks. Why don't we merge refrigeration with refrigerators instead? It seems to make more sense to me. lots of love, the magnificent evvy

Cool article

Thanks, Anome. It's a real cool article (brr!)

Ouch. Trekphiler 04:33, 10 December 2005 (UTC)

Freeze frame

I can see that the article is unfinished. I look forward to when it's frozen.

Patently unclear

The article on James Harrison says that he had a patent for a ether liquid-vapour compression refridgeration system in 1855. This article says 1876 by Karl von Linde. Which is it? Auric The Rad 19:27, Jan 21, 2004 (UTC)

Merge of refrigeration and refrigerator

First, the merge tags were added in such as way that the name of the article would be "refrigeration" and has nothing to do with which article is better or more complete. A refrigerator is the device used for refrigeration and there's not a lot about refigeration that does not involve refrigerators. The refrigeration article pretty talks almost exclusively of refrigerators (when I say "refrigerators", I'm referring to all refrigerators, not just home appliances). What do you guys think? -- Kjkolb 17:26, 16 January 2006 (UTC)

  • What I thought about the two articles was that I expected the refrigeration page to be more about the process, possibly in terms of the science behind it, rather than about usage in refrigerators. I think the best solution would be to transfer all the portions mentioning refrigerators onto the refrigerator page and add more scientific fact to that refrigeration page. To compensate for the link between the two, we can create a short and simple "modern use" section with reference to the refrigerator page.--Jonthecheet 06:20, 10 February 2006 (UTC)
I support Jonthecheet's idea. The Jade Knight 06:48, 16 February 2006 (UTC)
Merge. If motion fails, atleast move it to Unit Of Refrigeration per WP:MOS for Article Names. -Ambuj Saxena (talk) 16:40, 9 March 2006 (UTC)

I support Jonthecheet's idea in that I want to know how refrigerators actually work and what goes on in one...

Do not merge--Ted-m 03:08, 21 April 2006 (UTC)

As it is, the merge should go *the other way*. rerigeration is a process completely different from the appliance that is a refrigerator. Refrigeration contains mostly stuf that belogns in refrigerator. Circeus 18:53, 15 April 2006 (UTC)

No Merge - Let the refrigerator as a machine be left to its own article. Let refrigeration as a process be left to itself. It has been suggested that this article be reorganized, and I agree. I am also looking for someplace to link my red word ice making machine from another article and I think I can do it here if there is a little more historical integration and then applications lists with not so many breaks in the article. I would like to undertake organizing this. Refrigerator can be a "see also". Magi Media 04:29, 25 May 2006 (UTC)Magi Media

Merge of "Unit of refrigeration"

The article "Unit of refrigeration" had some incorrect information. It was corrected and merged into Vapor-compression refrigeration. The article "Unit of refrigeration" no longer exists as such and it is simply redirected to Vapor-compression refrigeration. Therefore, I removed the merge tag for "Unit of refrigeration" from this article. - mbeychok 19:05, 11 April 2006 (UTC)


(durgesh pandey)

This article needs improving

It has too little substantive text and too many links. For example, two of the sections ("Science and Technology" and "Speculative uses of refrigeration") have nothing but links ... no text at all. Another section ("Commerce") is almost the completly lacking anything but links. Also, the section on Thermodynamics of refrigerators is woefully inadequate and has no real discussion of the specific and pertinent thermodynamics that apply. I am therefore tagging this article as being in need of expert attention.- mbeychok 21:30, 11 April 2006 (UTC)

You were right about the article needing improving. I have done the redact as I said I would and left the technical stuff in from the old article which has techno-nerd appeal. Magi Media 02:21, 28 May 2006 (UTC)Magi Media

Notes on the Merge

Now we all know that refridgeration is a process that happens IN a refridgerator, so why shouldnt we merge fridge with refridgeration? Kinda makes more sense to me that way, but maby thats just me...Teh Teck Geek 00:46, 26 April 2006 (UTC)

The unsung invention (no merge)

I vote NO

I read that the refrigerator is considered the unsung invention of the 20th century. That much ability to generate clean wholesome chilling and freezing in one compact appliance within the home has changed the patterns and value of home food storage in terms of available family diet and sanitation. The refrigerator article needs to play up that "unsungness." So don't merge Magi Media 02:08, 28 May 2006 (UTC)Magi Media

Trucks

Refrigerated trucks (or simply refrigerators) are used to transport perishable goods, such as, for instance, frozen foods, fruit and vegetables, and temperature-sensitive chemicals. Most modern refrigerators keep temperature -40...+20 °C and have a maximum payload of around 24 000 kg. gross weight (in Europe). Surprisingly, refrigerated trucks are most wanted in winter, when there is a significant demand to transport chemicals under relatively high (+10...+20 °C) temperature

This sounds a bit confusing to me. I would assume that while it's true that they are most in demand in winter, they way it's written now may be misleading. I'm guessing refridgerated trucks are used far most commonly for transporting food (at low temperatures) then chemicals (at low or high temperatures). However I'm guessing for various food safety and perhaps stricter temperature range requirements, refridgerated trucks are almost always used when food (except for some cases of fruit and vegetables) is being transported however when chemicals are being transport, they are less likely to be used unless the temperature is low (or high) enough for it to be a concern. Therefore, refridgerated trucks are in most demand in winter as they will be used for food and for chemicals whereas in summer they will be used for food but not so much for chemicals. Also this bit on winter needs further clarification in another area. Obviously for places without winter, the issue doesn't arise. But what about for places with a milder winter? Nil Einne 19:11, 4 May 2006 (UTC)

tdp Please do not merge -- simply two-way link the entries. The concept of refrigeration vs. the implementation of refreigeration (refrigerators) are two distinct elements of knowledge. One is abstract (potential) and ripe with "possibilities" which lead to, when combined with "concepts" from physics, chemistry, and engineering to probabilities and actualities --different machines using refrigeration or refrigerators. --tdp 15:49, 28 May 2006 (UTC)

Refrigeration Lifespan

I was wondering if anyone knows of any links (in wikipedia or elsewhere) for the refrigeration lifespan of foods. For example, chocolate, fruits & eggs seem to last quite long in the refrigerator (>1 month), whereas bean sprouts & mushrooms cannot last more than 2-3 days. Is there any links on this anywhere on the internet? --Nathaniel 12:16, 1 June 2006 (UTC)

Refrigeration technologies

Dears,

I wonder if it would be nice to classify all different kinds of refrigeration technologies and list their pros/cons. I just saw some, but there are several more not listed.... all the solid state ones (thermionic, thermelectric, magnetcaloric, electrocaloric, barocaloric, elastocaloric), stirling (thermoacoustic, pulse-tube), etc....

I would love to see a topic like that and am willing to contribute with the knowledge I have... --Grandonia 12:00, 6 June 2006 (UTC)
Hello, as a separate point on referigeration technologies, shouldn't there be some connection between all these articles on refrigeration and the article on the Joule-Thomson effect. Also, could someone who knows add a comparison of Joule-Thomson coolers with vapour compression coolers. I thought that they were the same thing, but maybe not in view of the phase change involved. Thanks
User:217.206.155.116: Yes, the Joule-Thomson effect (achieved by the expansion of a gas across a throttling device) is used in some types of refrigeration. However, that is quite different from the flash evaporization (which is achieved by the depressuring of a liquid across a throttling device) which is used in vapor-compression refrigeration.

I also vote against the merge

I also vote against the merge. The "refrigerator" is a kitchen appliance for home and restaurants. On the other hand, "Refrigeration" is about the how the process of producing refrigeration works and the various industrial methods of implementing refrigeration like Vapor-compression refrigeration, Absorption refrigeration, Gas absorption refrigerator, etc.

The merge tag was placed on this article almost 6 months ago and the votes since then have been:

Thus, 6 "Against" and 3 "For" looks like the "Againsts" definitely have won. Therefore, I am going to be Bold and remove the merge tag. - mbeychok 02:48, 18 June 2006 (UTC)


Definition dejected

I thought my definition of Refrigeration as derived from the Meriam Webster version was adequate enough for an opening: Refrigeration is defined as a process of making or keeping [things] cold or cool, or freezing or chilling (as for food) for preservaton. The process of refrigeration can be characterized as done by either natural or artificial means, by whichever temperature can be lowered by transferring heat away from a space or a substance.

But I must defer, though dejectedly, to a definition made by a proclaimed chemical engineer User:Mbeychok Magi Media 03:28, 29 June 2006 (UTC)Magi Media

Magi Media, please don't take my revisions as a personal affront. But ".. by whichever temperature can be lowered by transferring heat away .." just simply didn't make any sense. I am positive that part was not in the Meriam Webster dictionary. Also, ".. keeping [things] cold or cool .." wasn't exactly very encyclopedic, was it? Things?? :) <== That's a smile and I hope there are no hard feelings. -mbeychok 04:27, 29 June 2006 (UTC)

Should the "The Montreal Protocol" section content be moved to the Montreal Protocol article?

Although I Wikified and re-formatted the the "Montreal Protocol" section of this Refrigeration article added by User:75.24.212.178, I think most of it really belongs in the Montreal Protocol article. I think it needlessly lengthens this article. It could be briefly mentioned in this article and linked to the Montreal Protocol for those who want more details.

What do others think? - mbeychok 07:14, 4 April 2007 (UTC)

Absolutely not. That's a very relevant piece of information in regard to the subject and I wouldn't have known about it if it wasn't in here! Sorry. I have a problem with the following terribly horrible incomplete information:
"The Freon patents were initially held by the automotive industry who used it for auto air-conditioning, but the product was far too useful to limit to automotive use. By 1930 Freon was available on the open market."
How did this happen?? What was done to free the use? Were the patents declared null and void, or what was the arrangement? --194.251.240.114 23:44, 30 April 2007 (UTC)
Would not a brief few sentences and a link to the Montreal Protocol article have led you to the complete article? It seems to me that would have sufficed and would not burden this Refrigeration article needlessly. - mbeychok 00:13, 1 May 2007 (UTC)

You need Wikipedia:Consensus before doing something like that. The quote from .114, above: " That's a very relevant piece of information in regard to the subject and I wouldn't have known about it if it wasn't in here " shows that you don't have it yet.--Old Moonraker (talk) 20:40, 17 December 2008 (UTC)

Did I miss something? Does the Montreal Protocol not have it's own article? Please explain why it needs to have two. —Preceding unsigned comment added by 71.67.157.174 (talk) 11:34, 18 December 2008 (UTC) SteveOak25 (talk) 11:47, 18 December 2008 (UTC)

Yes, user SteveOak25, you are missing something: Wikipedia:Etiquette in respect of achieving consensus and respecting the views of other editors. A correct way to deal with the duplication might be as suggested by Mbeychok, above: Have a brief few sentences here with a {{main|Montreal Protocol}} link to the complete article. I don't know why this wasn't followed up at the time. Blanking all of the the material five times without an explanation seems to me to be vandalism. Furthermore, it puts you in violation of the three revert rule. --Old Moonraker (talk)

Page Edit and a few other things

I modified the first section in agreement with the following comment;
"Mechanical work?? In the first line, the statement is that mechanical work is required because of the 2nd law of thermodynamics. But surely it's just work in general. E.g. the ammonia based fridge uses a heat source and has no moving parts, and even a normal fridge just uses Joule-Kelvin expansion to cool down. Then there's magnetic cooling etc. Grj23 11:47, 24 February 2007 (UTC)"

Also- I disagree with the merge, and I DO think the Montreal Protocol stuff goes into the Montreal Protocal Wiki.
Finally- I think we should try not to use the word "freon" as it is a trademarked name, but has also been used in the industry to apply to all refrigerants much like the word "coke" is used by some to refer to all carbonated beverages. We should say CFC- based refrigerant, refrigerant, or name the actual type when it is necessary. johntindale 20:53, 19 May 2007 (UTC)

johntindale, thanks for your edits of the article. I only want to let you know that I made just a very few minor copy edits to improve the grammar/flow of your edits. Regards, - mbeychok 23:41, 19 May 2007 (UTC)

Reasons for deleting two of the "External links" as well as the "clean-up" tag in that section

I deleted the external link Refrigeration World because it was a blog and did not contain any useful content. I also removed the external link The Food Refrigeration and Process Engineering Research Centre because it was simply publicising a university research center.

I then deleted the "clean-up" on the "External links" section because it was no longer warranted after removing the above mentioned two links. - mbeychok 00:01, 20 May 2007 (UTC)

Usage of word "vapor" rather than "vapour".

The word has two spellings, namely "vapor" and "vapour". It is my understanding that Wikipedia policy regarding words that have alternative spellings is that the spelling used in the earliest chronological introduction of such words in an article shall be used in that article from then on.

The word "vapor" was first introduced in this article on 11:58, April 11, 2006 when it was added in the then existing "Technology" section as a link to the Vapor-compression refrigeration article. Prior to that time, neither "vapor" or "vapour" had yet appeared in the article.

The word "vapour" was later introduced on 01:54 May 14, 2006 by User:Surendra mohnot ... at which time both words "vapor" and "vapour" appeared in the article.

Since the first introduction of the word was "vapor" on April 11, 2006, I am accordingly revising all of the occurrences of "vapour" to "vapor". - mbeychok 00:33, 2 June 2007 (UTC)

Latent heat of fusion

The non-cyclic refrigeration section gives a latent heat of fusion for water of 333.1 kJ/kg while the Unit of Refrigeration section uses 334.5 kJ/kg in its derivation. My guess is the different numbers were each taken from some source and are probably both "true" in some sense, i.e. there are two ways to define the process and each one yields a different value for the LHF. I'll leave it to someone with more experience on the matter to fix them or at least provide some explanation for the discrepancy. --AndrewBuck 17:32, 23 June 2007 (UTC)

AndrewBuck, you have opened up a real can of worms and rightly so.
  • Many online sources divulged by a Google search use 79.71 calories per gram.
  • There are two commonly used definitions of a calorie: the International Steam Table value is 4.1868 J/calorie and the Thermochemical Calorie value is 4.184 J/calorie ... see the online IUPAC definitions of a calorie at [1] ... and not a single source for heat of fusion values (that I found) defined which calorie was used.
  • If we use 79.72 cal/gram and either 4.1868 J/cal or 4.184 J/cal, we obtain 333.77 kJ/kg or 333.55 kJ/kg, respectively.
  • If we use 79.71 cal/gram and either 4.1868 J/cal or 4.184 J/cal, we obtain 333.73 kJ/kg or 333.51 kJ/kg, respectively.
I want to think about this a bit and decide which one of the above four values (i.e., 333.77, 333.73, 333.55 or 333.51 kJ/kg) would be most appropriate for this article on Refrigeration. Any comments by others regarding this topic would be welcomed. - mbeychok 20:50, 23 June 2007 (UTC)
After considerable thought, I decided that the correct heat of fusion for this article should be based on the value of 79.72 cal/gram using the thermochemical calorie = 4.184 Joules, which translates to 333.55 kJ/kg (as in the Heat of fusion article). Thus, the "Non-cyclic refrigeration" section was revised to say that the heat of fusion is 333.55 kJ/kg ≈ 144 Btu/lb ... and the "Unit of refrigeration" section was revised to use the same value for the heat of fusion.
I think we are indebted to AndrewBuck for having brought this subject up. - mbeychok
Thank you very much mbeychok, I was not expecting this to be resolved so quickly. You are a true testament to the power of the Wikipedia community. --AndrewBuck 03:59, 25 June 2007 (UTC)

Refrigerated coil

I'm afraid this has caused me some confusion: it states that "Avicenna invented the refrigerated coil", with the link going to dehumidifiers. Surely the point is that Avicenna was using a cooled coil for condensing his distillate and had in no sense invented refrigeration (although many sources state this). --Old Moonraker (talk) 09:13, 8 October 2008 (UTC)

Avicenna's coil was water-cooled and not refrigerated; his innovation was in the shape of the pot lid and coil (see here). I'm removing this. --Old Moonraker (talk) 23:26, 13 October 2008 (UTC)

Definition

While "refrigeration" can easily be defined in relation with the generic term "cooling", the current definition implies that natural cooling is also included, which is not correct. Hence, I would propose a simpler definition, as follows:

Cooling means removal of heat from an object or system, which results in lowering its temperature or in phase change. Artificial cooling down to temperatures lower than the ambient one (which spends human generated or harvested energy) is called refrigeration.

Please focus on the suggestion and do not argue with my anonymous IP! I am an expert in the area and play a role in many refrigeration-related organizations around the world. :) --212.73.146.73 (talk) 09:25, 15 June 2016 (UTC)

Refrigeration

Perhaps some clean up of the first line "Refrigeration is the process of removing heat from an enclosed space, or from a substance, and moving it to a place where it is unobjectionable."

That the space is enclosed does not cause the effect to be refrigeration, it could be anywhere. The place to which the heat is moved is not a determinate either. Consider a cascaded refrigeration system, the condenser of the first system is part of a liquid to liquid heat exchanger that is the evaporator of the second system.

Suggestion, Refrigeration is the process of removing heat from a localized area. SteveOak25 (talk) 21:20, 5 January 2009 (UTC)

Sentences should focus on refrigeration

This came from the "First refrigeration systems" section:

Meanwhile, James Harrison who was born in Scotland and subsequently emigrated to Australia, began operation of a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Victoria.

If I were doing a research on refrigeration, I wouldn't care if James Harrison were Scottish, Australian or Martian. I would be interested in what he contributed to the technology of refrigeration... and in the event that I become more interested in who James Harrison was, I'd just check out his article (there's a link to that). The phrase "who was born in Scotland and subsequently emigrated to Australia" distracts the reader from the subject of refrigeration. I've decided to re-word the sentence to "James Harrison from Scotland began operation of a mechanical ice-making machine in 1851..." His emigration to Australia need not be highlighted.

Units of Refrigeration

The section of called "Units of Refrigeration" has some good historical information in it. However, it is largely incorrect for the current industry. 1 Ton of Refrigeration (TR) is defined as precisely 12,000 BTU/hr. Secondly as this unit is defined in English Units, and is really only used where English units are used. It is rather nonsensical to have multiple SI equivalents, especially seeing as most of the rest of the World uses the Kw as the standard unit of refrigeration. I would recommend a rewording as follows.

The units of refrigeration are always a unit of power. Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling. For commercial and industrial refrigeration systems most of the world uses the kilowatt (kW) as the basic unit refrigeration. Typically, commercial and industrial refrigeration systems North America are rated in Tons of Refrigeration (TR). Historically, one Ton of Refrigeration was defined as the energy removal rate that will freeze one short ton of water at 0 °C (32 °F) in one day. This was very important because many early refrigeration systems were in ice houses. The simple unit allowed owners of these refrigeration systems measure a days output of ice against energy consumption and compare their plant to one down the street. While ice houses make up a much smaller part of the refrigeration industry than they once did the unit of Tons of Refrigeration has remained in North America. The unit's value as historically defined is approximately 11,958 BTU/hr (3.505 kW) has been redefined to be exactly 12,000 BTU/hr (3.517 kW).

While not truly a unit, a refrigeration system's Coefficient of Performance (CoP) is very important in determining a system's overall efficiency. It is defined as refrigeration capacity in kW divided by the energy input in kW. While CoP is a very simple measure, like the kW, it is typically not used for industrial refrigeration in North America. Owners and manufacturers of these systems typically use Performance Factor. A systems Performance Factor is defined as a system's energy input in horsepower divided by it's refrigeration capacity in Tons of Refrigeration. Both Coefficient of Performance and Performance Factor can be applied to either the entire system or to system components. For example an individual compressor can be rated by looking at the energy required to run the compressor versus the the expected refrigeration capacity based on inlet volume flow rate. It is important to note that both Coefficient of Performance and Performance Factor for a refrigeration system are only defined at a specific operating conditions. Moving away from those operating conditions can dramatically change a system's performance.

Please provide feedback on this post. I plan to change the "Units of Refrigeration" section to this sometime after 10/18/2010 if no one has any objections. —Preceding unsigned comment added by 198.36.95.12 (talk) 14:21, 4 October 2010 (UTC)

Refridgeration in history

Many old emperors had ice house: ie Zimri-Lin, Yongsheng Shensi, Tj'n Sje Hwang-ti, ... The "ice house" built at Yongsheng, in Shensi had a lock-mechanism and was situated near a river. I'm wondering whether none of these used a system similar to the Pot-in-pot_refrigerator, that would also be a very important thing to mention then.

As far as I know many large houses in the country in Britain had and "ice house". They were usually made as a smallish building over a cellar. The cellars were insulated for the best effect. Ice was harvested from any local source and stored in these cellars for use when cooling was needed. 2.102.129.125 (talk) 15:22, 26 December 2013 (UTC)Luke Wiseman

Introduction

Removing the third sentence as it is a slightly more technical and largely more ambiguous restatement of the first. Additionally the "this" does not refer to anything specific. Moving the last sentence to be the second sentence.

Original

Refrigeration is a process in which work is done to remove heat from one location to another. Refrigeration has many applications including but not limited to; household refrigerators, industrial freezers, cryogenics, air conditioning, and heat pumps. In order to satisfy the Second Law of Thermodynamics, some form of work must be performed to accomplish this. The work is traditionally done by mechanical work but can also be done by magnetism, laser or other means.

food storage optimum temperature

"Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F)."

It seems that for most food the ideal optimum storage temperature would be just above freezing, about 1C, 33F. Is this true?

It appears that this article's section Refrigeration#Unit_of_refrigeration has a more extensive discussion of the history of Ton_of_refrigeration. Should that page be merged into this page, or should that information be merged into Ton_of_refrigeration page, and here provide a "see main article" link?

There are benefits of maintaining a unique page for Ton_of_refrigeration.

  • Search engine hits lead directly to pertinent info
  • The unit belongs to the broader category of heat transfer, not refrigeration alone

Any thoughts? Nfette (talk) 23:37, 30 June 2014 (UTC)

non-cyclic refrigeration

Since the "non-cyclic refrigeration" section was empty, I took the liberty of putting some basic information in there. Hopefully someone with more knowledge on the subject will expand it if there is more to the topic. - Marcus erronius (talk) 21:11, 29 February 2016 (UTC)

Merge concepts of "air conditioning" and "refrigeration"? Comments requested

Please see

I think that descriptions of "air cooling" are all the same concept but somehow started to be described in multiples places. I am seeking advice on what can be merged together and where. Blue Rasberry (talk) 16:23, 6 March 2017 (UTC)

Grotesque

One of the most grotesquely overdetailed and discursive articles I've ever encountered. If I weren't phone-bound for another week I'd take a hatchet to it. EEng 21:19, 14 May 2018 (UTC)

Change: From point 1 to point 2, the vapor is compressed at constant entropy and exits the compressor as a vapor at a higher temperature, but still below the vapor pressure at that temperature. to: From point 1 to point 2, the vapor is compressed through an isentropic compression process and exits the compressor as a higher temperature vapor, but still below the vapor pressure at that temperature.

 Not done: You've made the text less concise but said the exact same thing. Why? Izno (talk) 23:19, 25 November 2018 (UTC)
