Ceiling or Climate Control?

[USAFpj]

For you guys who have 'been there, done that', may I ask what would be the most beneficial to climate control?

30x50x14 shop, with the peak at 19ft. Insulated throughout (just enough R value to control condensation). I love the shop, but have to run/empty a dehumidifier daily, and I stop operations between 1 and 4 due to the Summer heat.

I can spend the money on a multi-ton system which would give me the benefit of dehumidifying and climate control, but I wonder how comfortable it would be to just place a ceiling in at the 14ft level and not install a heat pump at all?

But now, the heat would just be closer to me

The ceiling with insulation will keep the heat from the roof up there provided there is venting. You would be cutting down area to condition. Is there just an r13 in the whole thing?
Don’t think I’d put in a minisplit until that was done.
The dehumidifier will run less as well but think I’d put a hose or pump off it so you don’t have to empty it. That’s a pain

Kaizen- I believe the insulation is R10, and yes, besides (3) 8ft clear panels on the side, it is fully insulated. I wanted ZERO condensation in this thing in our humid South. It's been good to me.

No venting, and the one drawback is the inability to see leaks in the roof..

You don't want to try climate control w/o proper insulation .. pay once.

With high humidity you don't want to oversize equipment -- and minimize outside air migration.

Does the slab have a VB?

Higher ceilings allow heat to rise and are more comfortable as long as the space is closed -- it's why old houses have high ceilings.

Ceiling fans need to be on down rods -- so as to not pull from the peak

Yes, a vapor barrier was placed.

I'd be willing to bet ceiling fans would help, but if you see how I figured the overhead lights, wouldn't there be a rather large 'strobe effect'?

I was thinking that oscillating fans secured to the corners of the shop would move air, (but that doesn't do much for my moisture control, which isn't out of hand.)

I call it helicoptering. Really bugs me for some reason. You have a tough environment for sure. Reducing the cubic feet you have will help as I said. Not sure in your area if you don’t have venting in attic if you should have insulation in roof and ceiling. I don’t think you have an either or situation. More of a which one first. Doing a minisplit first will be wasting a lot of money to try and cool without ceiling insulated.
