We have a Carver 53 Voyager (11 years old) with 4 self contained Marine Air AC/heat units factory installed. All units are running. Our long term issue has been the noisy unit in the salon, a 2 ton 230V unit. The unit is installed in a cabinet next to a couch. I have a picture of the installation assume picture up loading is a problem. When we had the boat in Ft Lauderdale several years ago I complained about the noise (I think the noise is 95% "compressor" noise) and a local contractor insulated the compressor. I think this step produced a marginal benefit in terms of noise reduction. Essentially …we live with the noise.

I got excited when I saw the Vector Turbo and the sound enclosure option….alas the product line maxs out at 16,000 btu/hr.  I think our application requires a 2 ton unit.

In summary, does anyone have a suggestion how we can reduce the noise?

In retrospect I think  having a 2 ton compressor operating in Salon in a "tight" enclosure (with no noise control) is a lousy idea.

Naturally a split system is one approach. At this stage that looks expensive, over $5000.

Another approach would be 2 one ton Vector Turbo's. The space is too tight for this approach.

Any suggestions?

Thank you.

Steve,

Good morning.

I checked my manual….I have a scroll compressor.

I understand the wood baffle idea. This presents another issue for me. Currently my manual  notes I should have 280 sq inches of RA. The Carver insatallation is not close to this. I have a picture but guess its about 10" x 15", coverd by a "decorative" grille and a washable filter behind it. In addition the unit is installed in such a fashion that the coil is 90 degrees away (plan view) from the RA grille. The scroll compressor is about 4 or 5" away from the RA.

Would my pictures help?

Thank you.

Got your last mail with the picture of the salon…Nice Layout  

Could that couch not be moved a couple inches Aft to get it away from that panel ?…I know you said it fits tight and I can't see the aft end…

It wouldn't take much to allow grill installation & enough added air flow…

Steve,

Good morning.

The AC unit is forward of the portside couch. So to speak just to the left of the furthest folding chair.The picture is looking forward, when I took he picture my back was so to speak against the sliding door.

The couch is tight fit…there isn't any space to move it. I wills ee if I can find another picture.

Ok…So I was right the first time, but yes with your newest picture I see the problem….

I guess your only option as I see it, is to enlarge the exsisting return air cutout & grill…How large is that area ?…

If you were to open it up to the limits…How close would that get us to the required 280 sq inches ?

We can always have a custom grill made to fit any size hole….
