A/C compressor unit in Flybridge bonnet over salon?

Mark Shoemaker
I have AC in the stack of a 30’ Voyager, just freon lines up and back… great location as cold air falls, have vents to salon and forward to pilot house.

Has anyone put an A/C unit in the flybridge bonnet over the forward dashboard on a W36 or W40?? It's a good place - sort of dead-space, and the vents could be directed straight down. Challenge is getting water up and of course drained back-down. The March-style A/C pumps generally don't have a ton of lift. M/V Weebles

I like the idea. My initial concerns are:

- vibration noise with the unit overhead. - it’s a long round trip run for the cooling water and those hoses are at least an inch in diameter. - not sure what head the pumps can tolerate - draining the condensate so that it doesn’t leave marks could be a challenge if the unit is run frequently. Positives are good use of an underutilized space (at least on my boat), short vent runs, it would automatically pull in the warmest air and put the cold air when it can be best used (this is a negative if the unit is reverse cycled for heat) and access for maintenance would be good. I don’t know if there are limits on the temps ain which these units can operate, but since many are located in engine rooms this might be okay. It seems like the locker could get hot if the sun is beating down on it. Venting louvers could be added to the locker doors. I’ve also thought about the lazarette but I think you would need a split unit for that location. My self-contained salon unit is located in the starboard cabinet and it doesn’t need ducting, which is nice, but the noise is right there when the unit is on. Servicing access is great. The fwd unit is under the vberth and has ducting to both cabins. The midship cabin is quiet while the fwd cabin gets the noise. The ducting eats up space. I have wondered about relocating the unit high up into the large locker that is used as a head in some other 40FBS. The condensate could then connect to the main cabin sink drain and use gravity rather than a pump. The ducting could also mostly be removed.

Another thought I entertained was to put the a/c unit in the fake smoke stack . On Sep 29, 2020 3:47 PM, "Steve Wurm via groups.io" <stevewurm1=gmail.com@groups.io> wrote:

I have thought about that same location. Its another item on the long list of things to do. Definitely an ideal centralized place for cold air to enter the boat.
