An air conditioner is quite similar to a dehumidifier. However, the major difference between the two is that the air in a dehumidifier passes over a series of cooling coils (or evaporator) and immediately over a set of heating coils (condenser) and back into the room as drier air.
In an air conditioner, on the other hand, air is passed over the cooling coils and then into the room. Then the heated Freon goes thorough a tube (outside the house) and into the heating coils and outside air passes over it, before exiting.
A dehumidifier performs the important function of extracting humidity in the form of vapour from the air as well as keeping the surrounding air cool. The only manual effort that needs to be taken is to empty the pan when it is full of condensed water.
Air conditioners have various user-friendly features. The most striking feature is the turn-off switch. It gives a signal to indicate that the pan is full with condensed water and that it needs to be emptied. This makes sure that there is no overflow and water spillage. Other distinct advantages of an air conditioner dehumidifier are:
• It drives away bad odour
• Humidity is maintained to a comfortable level
• It prevents fungus formation by maintaining the humidity levels
