thermoelectric air conditioning refrigeration system
#-Link-Snipped-# - cooling system(current flow hot junction to cold junction)
It is discovered by Peltier in 1834, there was little practical application of the phenomenon until the middle1950s. The poor thermoelectric properties of known materials made them unsuitable for use in a practical refrigerating device. It is only from the mid 1950s at which the major thermoelectric materials designed approach was introduced by A.v.loffe to the invention of the semiconductor compounds such as Bi2Te3 which is currently used in thermoelectric coolers.#-Link-Snipped-#
