Discussion Overview

The discussion centers around the manipulation of a thermocouple's cold junction, particularly in the context of its potential application in refrigeration. Participants explore the theoretical and practical implications of using thermocouples for cooling, referencing the Peltier effect and seeking deeper theoretical insights.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether a thermocouple's cold junction can be electrically manipulated to simulate a colder temperature, suggesting the possibility of creating a refrigerator from thermocouples.
  • Another participant identifies the Peltier effect as a known phenomenon related to thermocouples that can facilitate cooling.
  • A different participant mentions existing camping coolers that utilize thermocouples, highlighting their practicality and absence of moving parts.
  • There is a request for links to detailed theoretical information on thermocouples, specifically regarding electron quantum theory.
  • One participant raises a question about the potential for reversing entropy through the electrical manipulation of the cold junction.

Areas of Agreement / Disagreement

Participants express varying levels of interest in the feasibility of using thermocouples for refrigeration, with some supporting the idea while others focus on theoretical aspects. The discussion does not reach a consensus on the manipulation of entropy or the practical implementation of these concepts.

Contextual Notes

Participants reference the Peltier effect and thermoelectric devices but do not fully resolve the complexities of manipulating thermocouple junctions or the implications for entropy. There are also requests for further theoretical resources that remain unaddressed.

Can a Thermocouples cold junction can be electrically manipulated.
Can a Thermocouples cold junction can be electrically mimicked to be a colder one; thus is it possible to make refrigerator out of thermocouples?
electrons flow from hot to cold junction right ?
can anyone give me link to more detailed theory of thermocouples using electron quantum theory?
 
Engineering news on Phys.org
The effect is known as the Peltier effect. It is a common way to cause cooling using thermocouples...do a search, there should be plenty of information.

Camping coolers for food & drink are available, powered via the car's cigarette lighter socket. No moving parts!

How about?

... a directory of information on Peltier Devices, also known as thermoelectric coolers (TE or TEC), thermoelectric modules, heat pumps, and thermoelectric power generators.
