Which is one of the non-conventional refrigeration methods used for producing low temperature on the basis of the reverse seebeck effect?

  • A.Magnetic refrigeration
  • B.Thermoelectric refrigeration
  • C.Liquid gas refrigeration
  • D.Refrigeration of dry ice

Answer: B

Thermoelectric refrigeration produces low temperature by the reverse of the Seebeck effect, which is the Peltier effect: a current passed through a junction of two dissimilar conductors absorbs heat at one junction. Magnetic refrigeration works on the magnetocaloric effect, liquid gas refrigeration on the evaporation of a liquefied gas, and dry ice refrigeration on the sublimation of solid carbon dioxide, so only the thermoelectric method matches the effect named.
