Note effect.Dehumidification by condensation is that direct current is realized by one or more pairs of N-types and P-type semiconductor.
In refrigeration mode, direct current flows to P-type semiconductor from N-type semiconductor.The temperature drop of thermoelectricity centering cold end, and
And heat is absorbed from environment.When electronics by the conductor of interconnection flows to N type semiconductors from the low energy end of P-type semiconductor
High-energy tail when, heat will be absorbed from environment.Then heat is transferred to other one end by electronics conduction, when electronics is returned
Heat is discharged during the low energy end for returning to P-type conductor.Multiple thermoelectricity just constitute thermoelectric device to linking together.
