A dehumidifier is an appliance used for household purposes, where there's a decrease in humidity in air. Since humid atmosphere causes many health issues, dehumidifiers are used. The standard degree of humidity in the air should be 30 - 50 percent. Dehumidifiers are employed in industries to maintain a certain level of humidity.
The most common type of dehumidifier is your refrigerative or mechanical dehumidifier. In the former dehumidifier, the moist is eliminated by a coil having a little fan in it. The mechanism of the dehumidifier is when temperature decreases, the vapour pressure also decreases which results in condensation of water from the atmosphere. The refrigerated coil is subsequently utilised to reheat the atmosphere that's effective in temperature regions. If you want you can make your basement a happier place using dehumidifier for basements.
In areas where there's low temperatures and low humidity level, a particular kind of dehumidifier can be used namely "Desiccant Dehumidifier" where there's a desiccant material to reduce the humidity and it has got high affinity towards water vapour. This desiccant material is exposed to high humidity air stream to collect water vapour which in turn is exposed to reduced humidity air stream where the moisture kept can also be collected. The stream employed in the former is dehumidified and latter stream is used to regenerate the desiccant. These dehumidifiers consume heat energy to produce the impact of dehumidification. There are 2 types of desiccants namely absorbent and adsorbent. At the former, there's a chemical change when they keep water vapour. Adsorbent attract increased water molecules through the air pores present in it and there's no chemical shift. The adsorbent material often used is that the silica gel. This material can be emptied by heat at a temperature of 160 - 170 oC and the warmth required is 4800 KJ/Kg water removed.
The very compact dehumidifier called "Electronic Dehumidifier" consists of low cost components. There is a heat pump to generate a chilly surrounding and there's no noise generated as there are no mechanical parts. Spray dehumidifier is used, when the temperature of water is lower than the dew point of the air flow. This spray dehumidifier resembles an air washer.
They produce a cool surface. There's a refrigerated coil along with a lover that eliminates moisture. These thermally triggered technologies use heat energy to heat or cool the refrigerative dehumidifier. Thermally activated technology in dehumidifier can be utilized as a natural gas burner.
Dehumidifiers are used in a variety of applications. It's used in food & beverage sector as an absorption dehumidifier. In baking industry, enrobing is done by these dehumidifiers to control humidity, product cooling system is done for frost free cooling and when the product is saved, dehumidifier prevents from bacterial growth.
In cereals, when coating is done, it eliminates agglomeration. In candy business, dehumidifier is utilized while panning is done in order to improve the quality of the product. While packing the candies, it is used to improve the sanitation facilities.
In biotechnological laboratory, dehumidifiers are used for sterile atmosphere within the space. In water functions, these are used to prevent condensation, whereas a pipe gallery is utilized. All these pipe galleries are prevented from rusting, deterioration and also the life of stained pipes is lengthy. The benefits of using dehumidifier would be to remove humidity, since humid air causes many health problems such as allergies, respiratory difficulties, damage of immune system, asthma. When excess level of moisture is discovered, mold and dust mites will be formed. Thus, using a dehumidifier is very advantageous for the men and women who live in moist areas.
