1) The concept of being too warm on a dive blows my mind. I obviously need to travel more.<br>2) Can you explain "heat index"?<br>3) Rather than build an AC unit with an integral reservoir for the condensed water, one might consider simply pumping any condensate to your VBT, if so equipped.<br><br>Sean<br><br><br>Sent from ProtonMail mobile<br><br>-------- Original Message --------<br>On Apr 2, 2019, 08:06, Cliff Redus via Personal_Submersibles < personal_submersibles@psubs.org> wrote:<blockquote class="protonmail_quote"><br><html><head></head><body><div class="ydp13f774e1yahoo-style-wrap" style="font-family: times new roman, new york, times, serif; font-size: 16px;"><div></div>
<div>To me AC on personal subs is an interesting topic.

Note that the cabin temperature reached 96 F, the relative humidly reached 85% and the heat index reached 146 F. To say that I could have used small AC unit in the boat is an understatement! One of the implications of this cabin environment was that I could not keep the viewport clear. I soaked the towels I had on board very quickly trying to clear the viewport. As a consequence, is was hard to see. </div><div><br></div><div>There are challenges in designing a AC system for small subs. Ideally, it would be self contained and easily removed for service. The unit is going to have a reservoir for capturing quite a bit of condensed water extracted over say a 6 hour design mission time. For my boat the unit would need to be small and compact. Would be nice if we could find a OTS small compact AC unit that was DC powered. </div><div><br></div><div>If any one knows of a small compact AC unit, send me the link.

And it occurred to me, while we discussed air conditioning systems on our personal subs, we were likely the only three people on the planet having that conversation. 'Tis a small collection of fellow adventurers.<br>
