Hot Shop Question.

[camardelle]

Starting to really warm up here in Texas. My shop is 16x30 and has 4 windows. It’s a TuffShed. Double doors make it pretty open. Still hot, although the roof vent helps I’m sure.

I just picked up a 24” fan from Northern. My question is which direction should I point it? I’ll put it at the double doors...do I have the airflow bringing air into the shop or pulling air out of the shop?

Thanks in advance.

I prefer it blowing directly on me, to get a bit of "wind chill". But I'm almost done with working in the heat. The mini-split a/c for my garage is supposed to arrive on Monday.

That’s a couple years down the line for me. Love mine in the house.

I almost always prefer a fan blowing directly at me.

I agree. Unfortunately I’m powder coating or using a spray accelerant on a finish when turning pens and such so that’s not really an option.

Fans are designed to blow, not really ****.

If you have a problem with it blowing directly on you, then have it blowing at the ceiling above you. It'll cause a nice circulation effect.

Another option would be to get a vent fan and mount it high in the peak of the ceiling to pull hot air out and draw cooler air into the shed.

When I spray paints, I typically have my box fan by the floor blowing across my legs. I'm typically spraying the paint above desk height, so the air blowing by doesn't affect it so much.

Also... It's a small world. I grew up in Willis. Most of my immediate family still lives there.

Wow! My wife’s last day in the school district is tomorrow. She graduated from here in ‘76.

I guess I’m asking if I’m better off trying to pull air into the shop or pull it out.

Someone else suggested to me about putting a fan in the rafters to draw hot air up into the ceiling exhaust. I think I’ll do that as well.

Wildkats!

I'd pull air in.

I still think a buried length of culvert which captures ground temps and directed into a garage is the cheapest bang for the buck. Screen out varmits. Goods size fan. Suggest a mechanical or civil engineer to come up with the appropriate dimensions or do what I usually do and just overkill it.

A guy might **** hot air out the top for cooling but for coating want to be pulling air thru a restricted area to draw fumes out, 2 different things.
For coating in a 16x30 would have a fan in one end and draw air thru a window in the other. Put a furnace filter in it if you need to keep bugs out. Put the sprayed work down to the fan end. I actually like the fan low and the intake hi, in a long booth will create a down draft and keep the overspray to a minimum in most of it.
I set up so I am shooting overspray in the major air plume and going with it as much as I can. , basically not spraying upwind. I have stands on pallets and can actually rotate pieces in the light and spray downwind.
Some of the same principles of this apply to the single room shop too. You wouldn't need make up heat so it can be done simpler. Hang lights up out of the spray plume. Mine clears so well I can keep them out of the way and hang in the ceiling too.

Funny, I was JUST looking at these yesterday. I resisted and ordered a gable fan. I don't think the fan will hold me off for too long though.

What did you get? What's the size of the area/shop? Ceiling height?

 

[readhead]

I would be looking at a window AC unit. They are pretty inexpensive these days. Insulation will stop some of the heat gain during the day. Keep the windows covered. Your only other source of air will be from outside so you will be bringing hot air into the building. Good luck.

 

[NUTTSGT]

Is it open to the roof inside ? Create an attic space and insulate to help keep the heat out.

 

[gnpenning]

Make sure your intake side is on the side that gets the most shade. Trees and other buildings may effect the placement. Pull in the coolest air you can. A mister after the fan can help. Separate attic heat from the rest of the building and make sure you vent it away from your intake.

Ordered a Mr. Cool Oasis ES, 18,000 BTU. https://iwae.com/shop/18k-btu-21-se...t-pump-split-system-wall-mounted-ha11840.html The garage is about 20x24, ceiling is 9.5 feet. Around here we have to deal with heat and an incredible amount of humidity. I can't wait get it fired up!

You have the advantage of cool nights and dry air. Right now it's 93 degrees with a "feels like" temp of 104. It's miserable to be outside. Summer hasn't even arrived yet. Within a month or so we'll have many nights that the low temp is in the 80's. Then it gets hot when the sun rises.

 

[camardelle]

I can relate here just North of you in Willis. I picked up a 24” high volume fan from Northern and while I wouldn’t want to spend the whole day out here I probably could. LOL n between cups I usually sit in front of it. Overall not bad but I’m anxious to hear how your purchase does for you. Just took this pic in the shop while I’m shutting down for the day.

Consider getting a cordless remote on/off that sits by your lathe, or wherever you are, clipped to your belt.

For those occasionally rare times you need to spray the accel, turn the fan off.

Just an idea.

[camardelle]

And a good one. Thanks Mark!

Insulating, a $500 window AC in a framed opening, and a $50 portable fan will gain you 6 months/ year of comfortable working in Houston Sauna.

Those rare cold winter days.. a 1500 watt plug in space heater near your lathe ...$25.. will be good enough in that building in your area.

I did the math before purchasing. Window shakers seem to mostly be rated at 10 SEER. The difference in electricity cost between one of those and a 21 SEER mini-split makes up the initial cost difference in 3 years in this area. After that you're ahead of the game. The payback comes even quicker if you also use the mini-split for heat. It uses around 1/3 of the watts per BTU that a resistance heater uses. So you can pay now or pay later.

Just make sure you figure in real world stuff like fancy $500 control boards dying.

Give me a good old school appliance, like a clothes washer, dryer, fridge ANY day over a new Star Wars one.

Just my experience, and opinion.

Different but parallel - Sister in Law had Minivan... all sudden headlights start coming on intermittently while she sat in house.. kept happening for a week.. turns out needed "body control module" or something like that, approx $600.

Funny, the worst my older cars had was a $10 headlight dimmer switch rotted from MN snow.


Again, just one Old Man's opinion.

Nice! Let us know how it goes! I was looking at something similar.
And yes, I'm a baby. At the beach or outside playing, I can handle a little warmer but I'm unhappy at 80+ in the garage. I got the gable fan installed yesterday and kept looking up today wondering why it wasn't on. The thermostat is set at 95 haha (it's in the peak of the roof and I guess it wasn't that hot up there).

Oooof, 100*, I'd probably give up on being in the garage if that's what I had to work with

That's why I bought a unit that has a 5-year parts warranty and 7-year compressor warranty.
