Dehumidifier

The condensation and dehumidification theory of semiconductor ，which is Based on the principle of thermoelectric refrigeration，is mainly the Seebeck effect and Perle effect. The Seebeck effect is the phenomenon that the N - type and P - type semiconductors convert thermal energy into electrical energy.however，Perle effect is the opposite ，which converts electrical energy into thermal energy.therefore，Perle effect plays a key role in the theory of thermoelectric condensation. Condensation and dehumidification is achieved through the direct current passing through one or more of the N - type and P - type semiconductors. In the refrigeration mode, direct current flows from N - type semiconductor to P - type semiconductor. In that case，the temperature of the cold end of the thermoelectric pair decreases ，meanwhile，the cold end of the thermoelectric pair absorbs heat from environment.The operational principle of dehumidifier for box-type transformer and control box is that hot and moisture air can condense when meeting the cold.Through electronic refrigeration method，Creating a regional temperature environment inside the product and using fan to make hot and humid air inside the box pass through that area，in that case，condensation will continuously happen，then the condensed water is drained out of the electric box through special equipment，in this way，the moisture content inside the electric box will decrease ，the relative humidity will go down，the other area of electric box will not condense any more.
