Many petlier effect based unit are amongst top ten dehumidifiers in dehumidifier reviews 2015.  We will compare this dehumidification unit with traditional compressor based dehumidifier working on condensation principle. Let’s start petlier dehumidifier reviews

Working principle of Petlier mini dehumidifier.

As mentioned before unit works on petlier effect which is nothing but creation of temperature difference when voltage applied to two different type of metal joined to each other. It mean when two different mental joined to each other and electric voltage applied then one metal become hot and other become cold and temperature difference crated. In this process also called as thermos electric effect since it relates temperature with electricity. A petlier mini dehumidifier consists of following parts:

1) Two heat sink made up of different material. It call cold side heat sink and hot side heat sink.

2) A petlier module which sandwiched between two heat sink to apply voltage.

3) A Fan which pull humid air and push dry air.

4) Electric circuitry, switches and casing.

How this small dehumidifier works?

When you start this dehumidifier, fan pulls humid air into unit and this air first encountered by cold heat sink where dehumidification take place. Moisture present in humid air is condensate into water. This process is very similar to that of condensation process with help of cold evaporator coil in compressor based dehumidifier. Please note that cold heat sink of this small dehumidifier is designed with smooth surface and grooved properly so that condensate water easily falls into tank placed below cold heat sink. After condensation entered humid air converted into dry air which again passed over hot heat sink and put outside.
