Air Conditioning Systems ~ CAD & PDF Files

Rua Fiola had no Air Conditioning as purchased. We had viewed another Vagabond 42 of the same design that had a Main Salon Unit mounted under the curved main salon bench seat, and the Rear Berth Unit mounted under the rear berth bench seat. Both the outlet registers and the return air looked as though they would short circuit air flow by poor adjacent register placements. We determined that the main salon should have a unit that also supplied air to the V berth, and that the rear berth register be fully directed in the berth itself. Both return air registers need to be 4 to 6 feet separation from outlet registers. It is not common knowledge that the Return Air path can provide excellent service OR be entirely defeating of good cooling.

Sizing air conditioners for the length of the boat and the normal heat load to be experienced is not difficult. Most manufacturers have sizing charts to make it easy. For Rua Fiola based is the SE USA and Caribbean the requirement is for about 25,000 BTU. This can be done one of 2 ways, a single 25,000 BTU unit or 2 units of 16,000 BTU and 9,000 BTU.
