Talk:Thermoelectric cooling

message: The SLT article on the peltier effect air conditioner was a bit short on details.  I'm puzzled as to why this is considered a new or patent worthy invention, as peltiers have been discussed as airconditioning and refrigeration devices for years.  The problem has always been the poor performance(10% of carnot?) of thermo-electric effect devices compared with compression cycle or absorbtion cycle coolers (40% of carnot).  Is there any other more detailed information? njh 12:12, 5 August 2005 (UTC)

message: as of June 2010, no reference has been made to the lifespan of these devices, do they degrade or lose efficiency over the years, or do they last for ever ? 79.67.5.229 (talk) 09:12, 22 June 2010 (UTC)
thread_title:  Longevity or Life of device 

message: Because heating can be achieved more easily and economically by many other methods, Peltier devices are mostly used for cooling.
I'd dispute that. Certainly a furnace or electric heater is easier, but economical? Certainly in terms of energy input a heat pump, no matter how inefficient, will produce more heat than the energy input alone would suggest. sitharus (talk) 20:54, 3 January 2011 (UTC)
replies: text: The word "economical" means either "less money" or "less energy". I guess here it's "less money". Feel free to reword, for example "...can be achieved more easily and less expensively...". :-) --Steve (talk) 21:52, 3 January 2011 (UTC)

thread_title:  Efficiency 

message: Will a product specification page from a ccd manufacturer saying that their product uses Peltier cooling will count as citation?
Check the 5th paragraph of link given below, titled "Chilled"

similar info can be found on many manufacturer's pages  — Preceding unsigned comment added by Ipcamit (talk • contribs) 12:39, 13 December 2012 (UTC)
thread_title:  Citation regarding the use of peltier systems in CCD sensors 

message: I can't find any evidence of this anywhere in the article, so if nobody contests my decision in the next week I'll remove the tag. It seems highly unnecessary. OwenVersteeg (talk) 04:55, 14 October 2013 (UTC)
thread_title:  "Written like a personal reflection" - is this a necessary tag? 

message: I've resolved the lack of citations in all obvious places. I've cited "Some Aspects of Peltier-Cooler Optimization Applied for the Glove Box Air Temperature Control." as well as some other reputable sources. 
If nobody objects before the end of the week, I'll remove the "Citations needed" flag at the top of the page.  OwenVersteeg (talk) 10:37, 15 October 2013 (UTC)
thread_title:  The lack of citations has been resolved 

message: === 2nd paragraphe: === 
This technology is far less commonly applied to refrigeration than vapor-compression refrigeration is. The main advantages of a Peltier cooler (compared to a vapor-compression refrigerator) are its lack of moving parts or circulating liquid, near-infinite life and invulnerability to potential leaks

TECs have limited life time. Their health strength can be measured by the change of their AC resistance. When a TEC gets "old" or worn out, the AC resistance (ACR) will increase.
Seems to contradict itself. I am no expert in the field, but some correction or clarification would be helpful.
:I also don't understand this. What causes them to wear out? They have no moving mechanical components and so should be very long lived. Am I missing something? 173.33.95.196 (talk) 02:04, 10 March 2015 (UTC)

message: The Peltier effect has not really been covered in the article. The difference in electron densities in the P and N materials is not a sufficiently good explanation. To alter the temperature there must be a change in the mean kinetic energy of electrons. The total density in related only to the total heat capacity.220.245.43.121 (talk) 03:02, 22 November 2015 (UTC)

message: Is the Seebeck constant in the first equation and the peltier constant in the second equation the same constant? If so, they should also likely be represented as the same constant Fort33dople (talk) 14:09, 29 April 2019 (UTC)

thread_title: Equation consistancy?

message: This sentence should be in the first paragraph or so: In refrigeration applications, thermoelectric junctions have about 1/4 the efficiency compared to conventional means (they offer around 10–15% efficiency of the ideal Carnot cycle refrigerator, compared with 40–60% achieved by conventional compression-cycle systems (reverse Rankine systems using compression/expansion).[11])  — Preceding unsigned comment added by Encyclopedant (talk • contribs) 20:38, 3 June 2020 (UTC)

message: Hi everyone,
I have noticed there is a citation tag on the article. I am going to start cleaning this up and finding some reliable sources. Would anyone be interested in working together on this? 
Thanks!

message: from the article:   "However, a well-designed Peltier cooler will be a mediocre thermoelectric generator and vice versa, due to different design and packaging requirements.".
