This is what ductless air conditioning is all about: Cooling the insides, merging bulky air conditioning units in with the furniture and leaving the noise of the compressing system outside. What more could one want!
Mini split air conditioning or wall mounted air conditioning even mini-split air conditioning are other names for ductless air conditioning. Some people call ductless air conditioning systems heat pumps. They pump out the heat from the room but this is not the best description for a cooling system that not only removes heat from the space it is meant to but it also removes humidity making the air conditioned space a comfortable place to be.
While until a decade ago the window ac was the dominating air conditioning device in the market architects and interior designers soon began to demand a better form of cooling and this gave birth to the central air conditioning system. This system had the cooling unit outside the building mostly on the roof tops. This also never used a compressor but mono bloc pumps to pump water into a mist through atomizers. The mist was intend to reabsorb ammonia that was evaporated when the heaters boiled the water it was dissolved in.
The evaporating ammonia cooled very fast when it evaporated cooling the pipes it was forced through by the heat and pressure generated in the boiling unit. The pipes it flowed through cooled fast and air was blown over these pipes and into air conditioning ducts that were installed above the false ceilings and in the walls of the building. This chilled air was blown into the rooms of the building through vents built into the walls and in the ceiling.
It is easy to see that installing these huge ducts that were constructed from tin and were more often than not one foot square if not more consumed most of the budget of the air conditioning. Besides this the architects had to design buildings around the air conditioning. This ducting was a time consuming job with many a contractor wishing for a better way to air condition a space.
Then came ductless air conditioning. This system had the compressor based freon refrigerant system. The compressor of the ductless air conditioning or ductless split or mini spli ac (call it what you want) was exactly the same as the window ac. The different was that the cooling unit was inside the room and the compressor with the condenser coils that give off the heat is outside and with it the noise as well.
This kind of ductless air conditioning installation is the kind of air conditioning products that architects, interior designers and contractors have been waiting for!
