I want to install a ducted system house with central
coil.
Designers / installers are trying to dissuade conditioning
separately (split system).
I have central air-conditioning-legendary comfort.
Which these systems cons / pros?
Why with us unpopular in Lithuania?

Central do not do that:

1-exchanger will say according to the rate of fresh air that normally you 400-700m3/ho
is not sufficient to cool the house twice .. as Visine conditioner unit hanging on the wall where you rewind through the self-only 500-600m3 / h (one kmbary)
2-all ducts to be insulated with at least 3 inches. if poorly insulated ceiling duct after the dew
+ 6 cm nužemės more than normal ceiling
3-complex individual room temperature control. requires automatic valves on each block with room thermostat. but if this were done when the room temperature desired valve closes and loss of fresh air
4-for cooling the whole house at once rather than every individual rooms are much more expensive. for example a room to be ~ 1.0 kW to maintain the desired temperature and the central air-conditioning all the time what powers the 4-5 kW, if not more.
5 large inertia of the system, ie the activation of a good half an hour passed until finally you start to feel something

Simple as it is better to split.
if you split gadna take a picture of the ceiling-mounted air conditioners in a
separate ventilation grille looks like a blow, and ventilation
and if you think blowing strongly split kd / triukšmauja take it one size larger inner
and let them work on the first speed - or hear once strong wind
