The advantage of recycling the air is that you will remove the moisture in the air, dehumidifying as well as cooling. Constantly running "new" air will add moisture to the system, and if humid enough, may lead to freeze up of the coils.

You're pretty close to the water there (what? 2 miles?) so you may be getting more moisture than you think. A cheap bulk polymer humidity sensor would tell you for sure.

His hot air thing sounds like hot air to me. Cost shouldn't be any different. You are cooling office air, and running that into the shop. So you are pulling fresh air into the offices. I think with the recycle, you'll be more efficient, lower cost.

Cooling air is 1/3 the cost of removing moisture. The heat of vapoization of water is high! Look of the low pressure charts on the steam tables.
