Cassette units work the same way as wall-hung split system units, with the difference being that cassettes are installed into the ceiling instead of on the wall.
Ceiling Cassette Air Conditioners
The most common type of ceiling aircon units are called ‘cassettes. They are best-suited to rooms with a false or suspended ceiling and are ideal for use in offices and shops. The main body of the unit is hidden within the ceiling void with just a very thin facia visible and it thus neatly ‘camouflage’ into the retail or office space. An important consideration for the installation of ceiling cassettes is that it allows for a more aesthetically pleasing look for air conditioning solutions.
These units have the unique advantage of being able to be placed in the centre of a room and blow cool or warm air in four different directions. A single centrally-mounted ceiling cassette can provide balanced cooling to an entire room or multiple units can be used for larger areas.
Despite the fact that ceiling cassette ac units are hidden within a suspended ceiling (the space that is above the square tiles that many offices have on the ceilings), they are easy to retrofit and can be installed quickly and with minimal disruption.
