Each and every answer was too long to be good. So posting a short answer. Every AC has 4 main component: Compressor (makes noise while working) Condenser Expansion valve (air losses the heat here / air becomes cool here) Evaporator (output of cold air) All the ACs that you mentioned are categorised by the placement of above four units in the AC. Window AC:   the simplest and cheapest of all All the four essential components are inside one box. Thus it is cheaper, but as the compressor is now closer to your room, you will hear a lot of noise. (It happens with some of our refrigerator’s compressor as well, we hear some noise while compressor is working) 2.   Split AC:   little more complex-advanced and costly. Now to reduce noise, they decided to shift compressor somewhere away from the people who are in the room (Imagine 5 star hotel, where comfort is everything and the client wants to sleep in perfectly silent room - so the ...

In a split system an outdoor unit houses a compressor, condenser coil and fan. The indoor unit usually houses an expansion valve, evaporator coil, fan and air filter. The air filter cleans air passing through the unit and prevents the evap. coil from getting dirty. Refrigerant is circulated around the system by the compressor which also compresses “spent” gas returning from the evaporator. From the compressor refrigerant gas passes into the condenser where it is cooled by air that is blown over the condenser coil, this air picks up heat from the gas that is hot coming from the compressor. The gas condenses (liquifies) in the condenser and moves to the expansion valve. When the liquid is released to the low pressure side of the expansion valve it flashes to gas, rapidly expending latent heat of vapourisation. This causes the gas to cool rapidly so that it cools the evaporator coil which it passes through next. In the evaporator coil the gas picks up heat from the room air which is ...
