[3e] Stating a Refrigerated Cargo Hold

[Varyon]

Note that "$500 more per ton" for a Spaceships Cargo Hold works out to "$500 per ton," because Spaceships Cargo Holds are free - or, rather, their price is low enough compared to all the other components of a spaceship you can just ignore it. Power draw is presumably similar, low enough you don't need to account for it (just like you don't need to account for the power draw of the computer systems in the Control Room). For volume, the guideline from Payload (B74) is 1 cubic foot per 20 lb cargo space; I believe Spaceships vessels tend to have a density somewhere around that of water, which would instead be around 1 cubic foot per 60 lb cargo space (Spaceships stats assume all cargo holds, fuel tanks, etc are full).

EDIT: Forgot this was about 3e, which I assume means you're using Vehicles. I think the Environmental Control system from page 77 would cover most refrigeration needs.
