<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top">Here's a 12VDC unit<br/><br/>http://www.tropicalmarineairconditioning.com/sheets/2425C.pdf<br/><br/>This one is dedicated DC, ..but I think running a similar sized AC unit off an inverter for dual power source options is worth considering. Powering the unit on the surface as I described in an earlier post. I don't propose diving with the unit running, but more so a pre and post mission environmental purge, particularly with the main goal of aggressively dehumidifying the cabin.<br/><br/>No space in these boats as you note, this requires upsizing accordingly, but carefully. I once calculated the volume of a sacrificed conning tower could be substituted for 48" and a shortened length for nearly the same weight, I forget the numbers for the moment.<br/><br/>These compact AC units can be plumbed as I described earlier, the heat exchanger would have to be purposely designed. The outflow
water of these units is pretty damn hot, much much hotter than the surrounding water.<br/><br/>I live through Vance's camel torture story for about five minutes every time I climb into my white SUV. <br/><br/>If I'm ever to build and have a practical Florida submersible, I've got to be cognizant of these issues and address then carefully. <br/><br/>Joe<br/><br/><br/><br/>Sent from Yahoo!

Put two adults in a small sub like the K250 and <BR>you sacrifice comfort for occupancy. Freon based AC units whether auto <BR>or household are not practical solutions for the traveling submariner, <BR>such as convention diving. There was zero space for such an AC unit on <BR>board the Boston Whaler used to tow SNOOPY out into the ocean, and the <BR>support boat was being tossed in 2-4 foot seas. It simply is not <BR>practical unless you are building a support boat specific for your sub <BR>diving and trailering it along with your submarine to the dive location.<BR><BR>The best solution for the average psubber is to use a small ice chest <BR>(six-pack size) stuffed with ice and then circulate cabin air over that <BR>ice. Use a small computer fan to force air over the ice
if necessary. <BR>The first refrigerators were nothing more than ice-chests, low-tech, <BR>easy maintenance, not super efficient but adequate to keep things <BR>relatively cool.<BR><BR>_______________________________________________<BR>Personal_Submersibles mailing list<BR><a ymailto="mailto:Personal_Submersibles@psubs.org" href="javascript:return">Personal_Submersibles@psubs.org</a><BR><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target=_blank >http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><BR></td>
