The most common type of dehumidifier is Refrigerative or mechanical dehumidifier. In the first dehumidifier, wet flies through a cooled coil with a small fan in it. The mechanism of this dehumidifier is when the temperature decreases, the vapor pressure decreases in the condensed water in the air results. The cooled coil is then used to heat the air which is effective in higher temperature ranges.
In regions where low temperature and low humidity, a special type of dehumidifier is namely "dehumidifier" used where a desiccant is to reduce the moisture and has a high affinity with water vapor. The drying material is exposed to air having high humidity electricity to collect the water vapor, which in turn is subjected to low humidity air flow, where the moisture is also collected maintained. This dehumidifier consume thermal energy to produce the effect of dehumidification. There are two types of drying agents, ie absorbents and adsorbents. Adsorbent attract larger water molecules through the pores of the air in it and there is no chemical change. This material can be reactivated by heat at a temperature of 160-170 ° C and the heat required is 4800 kJ / kg of water removed.
A small dehumidifier "electronic dehumidifier" is called, from inexpensive parts. Spraying dehumidifier is used when the water temperature is lower than the dew point of the air flow. When the moist air is saturated in which air is dehumidified when water is sprayed onto the surface.
An example of a dehumidifier Refrigerative is the "air conditioning". They produce a cold surface. There is a cooling coil with a fan which removes moisture. These thermally activated technologies using thermal energy to heat or cool the Refrigerative dehumidifier. The energy from the heat source may be in the form of heat. Thermally activated technology in the dehumidifier is also used as a gas burner.
It is in the food and beverage industry as an absorption dehumidifier. This dehumidifier prevents the product coagulates, corroded to break, and also the growth of bacteria. In the baking industry, this dehumidifier is by wrapping done to control the moisture content, the product cooling for cooling is frost-free and if the product is stored, dehumidifiers prevents bacterial growth.
While Candy Packaging is used to improve sanitation.
In biotech laboratory, dehumidifiers are used for sterile air into the room. remove the benefits of dehumidifier is moisture, because the moisture in the air causes many health problems such as allergies, respiratory diseases, immune system damage, asthma.
