Room air conditioning

Room air conditioners can be divided in two categories:

Window and portable air conditioners

The conditioning process is helped by two fans (one for the cold and one for the hot circuit) that improve the efficiency of the system. They are usually placed in bedrooms or sitting rooms so a low noise level is essential.

Split-system air conditioners

They are used for flat and house conditioning. The hot circuit (condensing unit) is separated from the cold circuit which is usually placed in an air handler inside the house. The air handler system is commonly placed in the basement or a dedicated room. The low noise requirement here is less demanding. The condensing unit is placed outside the building. For this reason the unit and all the components must be weather resistant.

Window motors, Condenser fans and Blower motors are usually single-phase induction motors (permanent split capacitor or shaded pole)
