HVAC Design

[Brandon]

--------------------------------------------------------------------------------

I have been employed over the last few months as an HVAC engineer at a small firm in CA. I was recently looking through the ASRAE handbook and came across a section regarding HVAC for boats! It stands to reason that any "nice" boat would require some degree of interior climate control but it actually never occured to me before. Anyways, I love boats of all kinds and they tend to hold a bit more interest than buildings, so I am wondering if there are any consulting firms or otherwise that do HVAC specifically for large boat designers or if it is something that is done by the naval architects themselves. Any information would be greatly appreciated...or even if someone might have a small project that they would like some free help on, something I could get my feet wet with. Thanks a lot, this is a long one. Brandon

I have generally done it, and seen it done in house - SNAME has two T&R bulletins, one covering heat loads and other criteria, and the other insulation values (insolation and insulation!) that are generally cited in most speciifcations.

If you look at the prep course for the NAME exam, you will see there are HVAC questions. This is why "psychrometry" (not "psychometry") is mentioned in the engineering disciplines covered.

SNAME? Do you happen to have the links to these T&R bulletins, I would be curious to see what they have to say?

Side Question: I know that one need not necessarily receive a degree in architecture to be a licensed architect, rather all they need do is work under a licensed architect for a prescribed time and then pass a rather difficult test...is this the same for naval architecture?

I would imagine that the systems generally spec'd for vessels of any appreciable range are generally ductless splits, but I really have no idea--which type of system is used more: ductless split systems, or package units with ducts?

Pre engineered systems are supplied to West Bay Sonship yachts by a prominent US manufacturer. Call West Bay at (604) 946-6226 and ask for Evan Damgaard, He'll tell you who the supplier is. .

California doesn't license in NAME most NAMEs in CA are licensed in ME unless they are doing offshore, in which case they are CEs or SEs. Those states who do license NAMEs generally require a degree in some engineering discipline, though there are exceptions. The rules are available at www.ncees.org

Unfortunately, you have to buy the paper copies. The Navy DDSs also cover this, but they too are hard for regular folks to get.
