In this article we will review mini dehumidifier which is based on petlier effect and which often call as petlier small dehumidifier or thermo-electric dehumidifier. This dehumidifier is first choice of many first time dehumidifier buyer due to its attractive price. And is useful too but for small spaces. 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.
Advantages and disadvantages this top rated dehumidifier.
Low Price: Price of this mini dehumidifier is much less than tradition compressor based dehumidifier. But if you are going to buy this dehumidifier for large room they your money going to be total waste.
Quite Operation: This unit do not contain any noise making or rotating part hence operation of this unit is very silent. But due to its low price quality of fan used in it will make noise over period of time.
Low Power consumption: Power consumption is extremely less. Unit runs of DC voltage. Overage power consumption if only 22 to 50 watts only.
Low Dehumidification Power: Extraction capacity of this dehumidification unit is between 0.5 to 1.25 pint per day only which is very less. hence this dehumidifier is suitable for small spaces like bathroom, cupboards etc. If you like to buy this dehumidifier for your bedroom or living hall then you will definitely get disappointed.
Quality & Reliability: If you consider working principle of design of product it is more reliable product but if you consider quality of parts like fan, heat sink and switched it is mot unreliable unit.
Low Dehumidifier speed: Since this unit equipped with small fan (which generally used in computer), intake air itself is very less (actually it is negligible). Due to this dehumidification speed is very less. And this mini dehumidifier is not at all suitable for large rooms.
