Humidity

THE'relative humidity, ie the index that measures the level of vapor contained in the air, is an important value that tells you whether a residential environment is actually healthy.

In fact, if the humidity is too high it can lead to the formation of mold and, in addition to damage plasters and furniture, prove to harmful to health. Conversely, even too dry air constitutes a non-optimal hygienic situation and may lead to difficulty breathing and hydration. In general it is considered "Living" an environment where the relative humidity ranges from 30% to 50%. To control the humidity of a room you can install a conditioner that reduces the relative humidity, or choose a well to impact on the temperature, dehumidifier. Task of a dehumidifier is exactly to lower that rate (without impacts on temperature that the air conditioner) and bring it back within the limits fixed by condensing the water vapor in the air.

there different models and types dehumidifiers within which you can choose one that is suitable to the specific needs of your environment. The first major division is between conditioners fixed and portableThe former are generally more powerful and effective but, of course, less practical, non-transportable and more complex to install. A further distinctive feature is then what concerns the technique through which the dehumidifier makes the lowering humidity: in dehumidifiers "passive"Or essicativi the humidity is adjusted by means of specific materials which have desiccant properties, the most common of which, but not the only one used, is the silica gel. Dehumidifiers "Mechanical-refrigerativi " instead use the cooling air sucked inside them to induce condensing riespellerla and, therefore, more dry. The second technical solution is more common because it works better if the "departure air temperature" is higher and thus more effective in the moments in which at our latitudes the humidity is high, or in the summer months.

Several are the factors of choice in view of a purchase of a dehumidifier: first of all its power as a function of the room volume to be humidified and its portability if you need to use it in different rooms. An important indicator is then l 'removable moisture, in terms of liters of condensate in 24 hours, the capacity the tank and the possibility of adjust the moisture content desired. Since all the air conditioners on the market also perform the function of the dehumidifier, many homes as Daikin and Mitsubishi They have virtually stopped the production of plants "fixed" dehumidification only, except for specific functions especially industrial. The "only" dehumidifiers on the market today are mostly portableRanging from 'Olimpia Splendid (20L / day) to a list 279 Euros all 'Argon Deolo 17 (17L / day) on the market to 229 EUR. There Ariston It offers the range Deos that, depending on the capacity of the dehumidifier 11 to 20 liters per 24 hours have a price that goes from 149 to 229 euro. finally de Longhi offering its range des with dehumidification capacity from 12 up to 25 liters per day with prices from 219 to 340 euro.
