Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
MERLIN is cooled using Thermoelectric elements, and can be cooled to -20 °C while using ISS water supply or -10 °C while only being air cooled. Resistive heating elements are used to provide an incubation capacity up to 48.5 °C.
The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...

The use of gas eliminated the need for an electric compressor motor and decreased the size of the refrigerator. However, electric companies that were customers of GE did not benefit from a gas-powered unit. Thus, GE invested in developing an electric model. In 1927, GE released the Monitor Top, the first refrigerator to run on electricity. [35]
The disassembled ARCTIC-1 unit. The inset images show the corroded thermoelectric elements inside the ARCTIC. Overall horizontal view of the Advanced Thermoelectric Refrigerator/Freezer (ARCTIC) 1 unit installed in Expedite the Processing of Experiments to the Space Station (EXPRESS) Rack 4. Unit connectors and cables are visible.
A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).
Thermoelectric acclimatization depends on the possibility of a Peltier cell of absorbing heat on one side and rejecting heat on the other side. [1] Consequently, it is possible to use them for heating [2] on one side and cooling on the other [3] and as a temperature control system. [4] Figure 1.
