They almost HAVE to put A/C on the Subs, just like any other small space with lots of people in it - each person is putting out 600 BTUH of heat just sitting in there, and lots more if they've been exerting themselves. And that heat load adds up real fast. Plus, they have to dehumidify the air they supply to the porthole vents, or they would fog up with all those noses pressed up against the glass.
Professor I. M. Boring's Ballpark estimate time: Let's see, the Subs seat 46, plus pilot is 47. 600 X 47 = 28,200 BTUH = 2.5 tons (30,000 BTUH) of AC needed just for the people load. Add in the sun and mechanicals and you'll need between 3T (36,000) and 4T (48,000). Don't go too big, or it won't run enough to dehumidify properly.
And it's really simple to build a small energy efficient A/C system whe you have all that fairly cool water to run through the condensers.
