Gord: actually you went with not only the largest BUT the most expensive to prove your point. There are others and I'll probably use 4 not just 2. As I may actually core
in 2 more dorades if 2 aren't sufficient.
4" Bilge blower
West Marine: West Marine Search Tool
ac system still costs at or in excess of a grand, and I'm not buying
You may continue to try to convince me to use water
but I have no intention of doing so, don't waste your breath. Ok Ok I know I mentioned it but I changed my mind so forget I ever mentioned building a water
David M: Correct, to attach to an existing system you need to consider the effect of reduced flow and volume to other devices on that system. You need to consider whether or not the existing lines and fittings need to be enlarged to accomodate a new device. If so, this costs $$$ and involves changing seacocks and thru hulls. NOT GOING TO HAPPEN. I am happy with the projected efficiency of air cooled and I ALREADY KNOW it works.
compartments are ducted and vented on gasoline engine
power boats as a USCG REQUIREMENT IN JUST THE FASHION I INTEND! My engine compartment already has ventilation and the air used is sea air(duh!) vented thru the existing dorades(Event Horizon). My intent is to increase efficiency by using forced air with bilge
blowers designed for just this purpose and 1 blower for the unusual purpose of cooling
the condensor (Thx to LtBrett who seems to get it).
When considering an idea one has to think things all the way through from beginning to end. Cost and effect. You can't just haphazardly say to, for example, tie in to the existing raw water
system without considering the potential consequences or the costs of making it work PROPERLY. As I said before use common sense and logic in all you do. I'm not just some schmuck who knows nothing of what they are doing. There are a lot of "armchair quarterbacks" out there who know a lot about sailing but nothing of engineering (Gord you are an exception to this as I am convinced you know more than God himself
Thanks for your opinions, I'm out.
Feel free to now hijack or close out this thread, I'm done.
