I wonder why the air aboard cruise ships has to recirculate so much—it seems like cruise ships are usually about 1/2 surrounded by breathable air at normal atmospheric pressure. Is it about heating and cooling, like, passengers would feel very uncomfortable if the air in their cabins had a lot of fresh sea air mixed into it? Do they do something to filter out the salt from the air intake?
- petertodd 7y agoBecause fresh air needs to be heated or cooled, and that's expensive when you're running everything off diesel. Heat exchangers do help, but they're not perfect, so every bit of outside ventilation costs money. This is why fume hoods which exhaust to the outside can be surprisingly expensive to run in cold/hot climates.
