Dehumidification: Staying Cool in High Humidity
Although it is not often referred to as an air conditioning unit, a dehumidifier that is used for removing moisture content from the air within a building really is one. Many dehumidifying units also function to cool air in a twin-use operation, although a good number of domestic ones are single-function only. When repairs are required to either twin or lone-operation dehumidifiers, an air conditioning services company should be called on. Both dehumidification and air conditioning works by a process of energy transfer so the principles for both sorts of system are the same. Let's take a close look at how dehumidifiers work.
The Refrigeration Cycle
Like most air conditioning units, a dehumidifier will commonly make use of a refrigeration cycle. However, a dehumidifier is different from a standard air conditioning unit because the evaporator and the condenser are both utilised within the same part of the device and have access to one air path. Although an air conditioning system transfers heat energy away because its refrigerated condenser releases the energy it captures externally, the same cannot be said of dehumidification devices. They condense airborne water onto their condensers which is subsequently captured in a tank or escapes via a pipe into a drain.
Dehumidification and Air Conditioning Together
Because the energy used by a single-function dehumidifier is used locally with no heat transfer operation, they can actually heat up a room they are in when working, much like a chilling cabinet would do in a retail store. As such, they ought to be used in conjunction with an air conditioning unit to keep a room cool. If not, the air temperature of the room will be likely to build up, keeping airborne moisture energised and harder to condense.
Why Use a Dehumidifier?
In Australia, moisture in the air is not generally a problem for most locations in the country and it can even be welcomed. However, mould and spores can build up in places where the moisture content of the air becomes too great. If you use a basement as part of your living accommodation, then you may have noticed this. Using a single-function dehumidifier will allow the moisture content to drop but the air temperature can be raised, especially if the device is left on constantly. Using one in conjunction with an air conditioning system will not only keep humidity and heat levels down but can protect your home's sensitive electronic components from airborne water damage.
