AMEL 55 -2012 — Replacing CLIMA aircon unit systems with a schiller central unit

Jose Alegria
 

The CLIMA® unit systems of my Amell 55 - 2012 are inefficient and very noisy.
Someone in the group has experience with replacing to a  central schiller system.
All imputes are welcome

 

Jose,

It is at least a very big job, and possibly almost impossible job. 

The size of the remote chiller blower unit is smaller than a typical drop-in Climma Compact unit, and the saltwater condenser plumbing throughout the 55 does not exist. It is only in the engine room.

I recommend that you exhaust other means of sound reduction. I have been on several 55s and I did not notice loud sounds...maybe something is wrong.

I hope this helps.

Best,

I had too CLIMA units that were noisey which was only the fan unit vibrating and rattling, I used some gentle persuading to some areas of the frame which stopped the issue, they all run acceptably quiet now

Bill, hi

Thank you very much for your opinion but I would like to detail the situation further and request your re-examination

The Amel 50 and 60 currently come equipped with a central chiller system  (Webasto ) and the last 55 at least from July 2017 have also been equipped with central chiller systems.

My actual situation: My 55 hull nº 3 comes with:
2 compact CLIMA in the aft cabin both of 3.5; in the saloon one of 7 plus other 12 and in the front  cabin another of 7; 5 equipments of a total of 33,000 btu, but 3,5 + 3,5 at the main cabin are clearly insufficient in places like Greece in July-August; They are totally ineffective and extremely noisy.
How to solve?
a) Installing new independent CLIMA or WEBASTO equipment,  increasing power in the aft cabin to at least 12-15 000BTU and benefiting from the fact that the most modern appliances have about 25% more cooling capacity,
b) keeping 5 equipment and also keeping the noise of the compressors in the noble spaces
or
following the current Amel philosophy by placing a WEBASTO  variable speed schiller  (Webasto V50) that drains only at 2.5 to 15 amp, not exceeding 5/8 amp in eco mode, and puts 5 air handlers (smaller than the compact units)
How change all pipes system?
Probably the path of the current saltwater circuit can be replaced by Schiller liquid (water and glycol).
I will also be able to take advantage of the condensate circuit to make the pipes pass through the same holes.
And maybe I need more new holes !....

I would be grateful for your more detailed appreciation of the issue.

Thanks in advance

Can you

For what it's worth, the aircon system on our Amel 50 is AMAZING! It is very quiet and works perfectly. The central chiller unit is in the engine room. If you can convert to it, in my opinion, it would be worth it.
