Dehumidification as A Ventilation Method

Buildings are after all a means of protection for people living in them. Design and construction of these are influenced by many things like culture, climate, local resources. Today, there are several international and national codes and guidelines that regulates the construction industry and mainly for the security of the society. These guidelines are often here to make sure that construction meet the quality needed. Moisture problems have been a topic of interest for many scientists.
In order to keep people living in buildings safe from harm, ventilation is a system that is supposed to be in charge of removing or diluting pollutants as well as controlling thermal environment and humidity in these living spaces. Pollutants and humidity found in houses are supposed to be removed with the presence of a sufficient ventilation.

Ventilation Methods

Ventilation can be supplied by different mechanical and natural methods. Like many things in life, these methods bring positive and negative effects, but it does prevent many health problems.
if not properly designed, installed, maintained and operated (Mendell, Smith 1990; Seppänen, 2004; Mendell et al., 2007), as ventilation can then allow the entry of harmful substances that degrade the indoor environment. When it comes to mechanical methods, devices should be properly designed and installed in order not to allow harmful substances to get inside homes which deteriorate indoor environment.

Indoor Air Dehumidification

One of these methods is dehumidification of indoor air. Using a dehumidifier, a cooling coil calculates the dehumidified air and condenses water which will be drained afterward and collected in a water bucket. After this process of dehumidification, the air is either heated or cooled by the same unit which will release it back to room temperature. According to The National Center for Biotechnology, these dehumidifiers are particularly effective for temporary use. It´s also recommended not to go lower than 45% of relative humidity when dehumidifying the air as it´s the the limit value for mites growth. One of the popular devices of this type today are Frigidaire Dehumidifiers and which are different in dehumidifying capacity — 30, 50 and 70 pint per day.
