Re: [PUP] CENTRAL AIR CHILLED WATER SYSTEM VERSUS STAND-ALONE UNITS
Hi All,
I am currently deciding on an air conditioning system for my boat.
The debate is between having the usual stand-alone air conditioning
units in each room, versus using the central system that uses chilled water,
and basically a small radiator and fan in the room.
I understand that the chiller system is the same as that used in big
buildings, and that they now make it in systems that are marine-adapted for
boats.
Note, I am in the tropics, so "winter freeze" sitting at dockside is
not an issue.
Thanks for the pros and cons to help me decide.
Mike
Hey Mike
The pros and cons are almost the same, the good thing is you only have one
central compressor unit with 2 pumps one for the chilled water and the other
with the condenser water so you have less units to break down, and or
replace next time, the bad thing is you only have one compressor unit
if/when it goes down you have no air in the boat at all whereas if you had
individual units chances are at least one of them will give you relief.
Personally I would prefer a central system I believe they are more efficient
and take less space in the bilge.

After having individual direct expansion units in my previous boats, I opted
for a central chilled water system in Que Linda. I made a mistake.
The main difficulty is that the compressor with the capability to cool the
whole boat draws a huge amount of power, frequently more power than the
shore power can afford. To be specific, the chiller requires about 35 amps
240 volts when running. When cooling one stateroom it is on a very low duty
cycle, (iow, it runs full power but only about 10% of the time) but the
shore power needs to be able to handle the peak load.
Individual units for each stateroom or each area on the boat would allow a
smaller shore power connection to cool just the master stateroom, for
example.
