To continue – and to somewhat wrap-up – the topic of ACs from previous blog posts, here we’ll talk about the different types of air conditioners. Most commonly we can summarize them like this:
1- Window ACs – as it’s understood by their name, those are the ACs that are mounted directly on windows. They
used to be quite common, but as of today – not so much so, although they are still being produced and sold. All of their components are in the body of the AC, together (not the remote control, of course). Their main shortcoming is the noise they make, as well as the needed adaptation of the window they’re mounted on. Maybe the only advantage this type of AC has is that mounting it is quite easy, compared to other types.
2- Mobile ACs – similarly to the previous type, all of their components are in one place (although there are some models with two separate bodies). The difference is that with Mobile ACs 
there’s no need for making that big of a whole – all they need is a small penetration for a tube to carry the air outside. We’d really not recommend a mobile AC, seeing how they too basically keep all the noise inside, which is completely impractical. These types of ACs are most commonly made by Chinese brands.
3- A split system air conditioner – in contrast with two previous types, here the AC is divided into two separate bodies – an outside body and an inside body. The compressor is situated in the outside body of the AC, together with a heat exchanger, a fan, most of the electronics and other components. In the inside body is the other heat exchanger, another fan and the rest of the electronics. The rest of the parts’ depends on whether the AC is designed both for cooling and heating, or just for cooling. The advantage of the split system is that the compressor is on the outside which significantly lowers the noise in the room. Other advantages are obviously the huge diversity in models and price ranges. A disadvantage is the significantly more complicated mounting of the AC, however when done by professionals that’s not a 
problem.The split system – depending on their inside body – can be:
(a) Wall AC (shown here)
(b) Wall-ceiling AC
(c) Floor-ceiling AC – these types of air conditioners can be mounted both on the ceiling or on the floor and the condense tray is designed in such a way that it doesn’t matter of the AC is mounted vertically or horizontally.
(d) Cassette AC – for suspended ceiling
(e) Column AC – some brands offer this type of AC. They are called Column AC because they are mounted directly on the floor and because of their huge column-like size. They are much more powerful than most of the other models, circulate a much grater amount of air and are not suitable for a home.
4- Multi split AC – These work on the same principle as a Split AC, with the added difference that with a Multi Split AC you can connect one outside body to several (usually 2 to 4) inside ones. It’s also possible to connect different types of air conditioners with the outside body – one cassette AC, one wall AC, etc. Some of the disadvantages are that all the inside bodies must be working in the same mode – you can’t have one body set on cooling, while another is set on heating (although some can be turned off, while only another is working). Also – if something brakes in the system, usually all of the inside bodies won’t be able to work until the problem is fixed. If instead you just have multiple split systems instead of one multi split system, than if one brakes, the rest will be able to keep working.
And that’s a more or less complete summation of the different types of air conditioners. We hope you’ve found it useful!
