DEHUMDIFIER

2.1 Dehumidifier introduction

A Dehumidifier is a home appliance which reduces the level of humidity in the air usually for health comfort condition or eliminate musty odor from atmosphere. It is applie for removing moisture from the air as for lowering the humidity in room.
Dehumidification is combination of absorption and regeneration process carried out alternatively in given time.
2.2 CLASSIFICATION OF DEHUMIDIFIER
2.2.1 Mechanical Dehumidifier
Mechanical dehumidifier is work by moist air of refrigerated coil with a fan and compressor. The cold evaporator coil of the refrigeration device which is condenses the water which moisture is removed then the air is reheated by the coil. The reheated air is released into the surrounding room. This …show more content…

The design is simple and advantages of being silent compare to with Mechanical Dehumidifier. It is less Coefficient of Performance and this is used for small dehumidifier. Ice making is difficulty with refrigeration dehumidifiers. Fig 2.2.4 Thermoelectric dehumidifier
2.2.5 Desiccant Dehumidification
A process uses a Moisture absorb material is also called desiccant. which is uncovered to the surrounding air to be cooled and dehumidifier. The humidity absorbing material is move to a different place where it is recharge by reheating air.
Dehumidifier is work on absorption principle are specially for high humidity level at low temperatures. They are used in industry and commercial and residential building because humidity levels below 35% can be achieved.
Lack of compressor parts desiccant dehumidifier is lighter in weight and silent in operation than Mechanical Dehumidifier. Desiccant dehumidifier can also operate at lower temperature than Mechanical dehumidifier the unit lacks coils which are unable to extract moisture from the air at low
