The way dehumidifiers work is similar to the way condensation forms on a cold window. A dehumidifier holds a compact refrigeration system which makes it the coldest place in the building. Air is drawn into the cold dehumidifier where any moisture in the air condenses, is assembled and removed. There are two main types:

The operation of refrigerant dryers

Refrigerant dryers cool air intake substantially by means of an evaporator section in a closed refrigeration system. As a result of this cooling, the relative humidity of the air over the evaporator rises to 100% and water vapour condenses. This water (or condensation) is either drained into a reservoir or through a hose to a drain, water container or a suitable outside location. The heat generated in the cooling scheme condenser is used to warm the returned air to a temperature above that of the primary intake. Each time the room air is passed through the dryer a amount of moisture is got rid of from the air, hence the humidity within the room is reduced. Refrigerant dryers are specifically positioned within the room to be dried and require little attention whilst in operation.

The operation of desiccant dryers

A desiccant dehumidifier uses the hygroscopic properties of moisture-absorption materials such as silica gel or lithium chloride. These materials are impregnated within a rotating ceramic wheel, over which the humid air from the room is blown. The hygroscopic material absorbs a huge part of the moisture from the air, hence reducing the humidity in the area. The wheel is left very wet, it then proceeds to rotate tardily and the division which is completely filled with moisture is heated with an electric heater, to vaporise the water. This warm and very humid air is then expelled outside through a length of flexible ducting. As well as being capable to place a desiccant unit within a room that is to be dried, desiccant dryers are oftentimes used in apps where it is not possible to position a dryer, such as hazardous areas or areas with fixed access such as pipes and tanks.

Selecting the right solution

Before choosing a dehumidifier solution, it is indispensable to basi take an account of the surroundings and space that requires treating. Some of the fundamentals that need giving careful consideration to are:

What is the extent of humidity in the area?
What is the size of the place/area?
Is the building occupied or empty?

There are respective models and types available – a good deal of of which are better suitable to littler apps with less complicated controls and galore for big scale industrial use or on construction sites. In a great deal of situations, in particular after flood damage, dehumidifiers operate more expeditiously if applied in conjunction with a heater and fan. For the most suitable model it is best to ask for counsel as experts will do calculations using a hygrometer and psychrometric chart. They will also offer counsel when it comes to the best way to seal a room before the dehumidification routine starts and positioning of the units.
