Can a Thermocouple's cold junction can be electrically manipulated

[sr241]

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?

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.

Can entropy be reversed by electrically manipulating cold junction of thermocouple to a cooler one
