Title: How hot does it get in your shop?
Post by: Sundaybest on July 10, 2019, 02:37:08 AM
I have a 1,500sq ft warehouse an today it got to 95 degrees. Are portacools worth it?

Hovers between 82 - 95 degrees in here depending on the humidity outside. I don't turn the AC on, just not worth it. The thing drips like crazy and when the dryers are on it's not even doing anything. I stick with fans in strategic locations. I can bare the heat as long as there is some sort of a breeze coming at me. I thought about the portacools but I'm not sure they're really worth it in a larger space with high ceilings.

Mid 80's with the AC on.

Yes, portacools do a great job if you are pulling enough air out of the warehouse.  They do nothing but jack up the humidity if you don't exchange the air.

The trick with them is turn the water down so you see dry spots on the coils.  That way you know the water is evaporating.  Also, I hate to stress this too much...AIRFLOW.  We have 2 exhaust fans for about 3,000 square feet.  I know one of them is rated 1,200cfm, I think the other is right around there or a little larger.

It's all about air exchange. Get the air in, like a motor, then out like an exhaust.

Swamp coolers work great in low humidity areas.

Right under AC piped over operators...70.

Butt sweat 99, head freezing.

We just had ac installed blowing straight down above operator, puller and catcher stations. It is a BIG difference. Shop is still hot, this morning we started at 5:30 and it was 85, its 96 right now with 65% humidity. AC makes setups go faster too, everyone is rushing around trying to get back to ac stations, lol.

Ours works great here in high humidity...ask Greg Kitson.  He was impressed with ours when he was here.  We have since added more airflow to the shop and it's even cooler back there.  On rainy or really high humidity days it won't work well, luckily down here the heat can burn off humidity pretty quickly.

It's 100° today... but there are portable ac's blowing on each person to make it tolerable. For us, it's getting the heat out, I had this conversation last week here...

I got lucky my shop use to be an old restaurant, so I have air through out the building and can shut down the shop area from the office area if we need to, our norm in the shop at full production is around 85/90 because I shut down some of the air vents so it won't effect the dryer. ;D

We used to see near 120. We put in regular fans on the side of our shop wall (in wall) and that knocked a good 10 degrees off. Then when we had our fire (rented area) and we repaired the building we took over the rented side and knocked the wall down between us. So now the shop is just open to cross breeze when you open our garage doors. So its hitting 95-100 now on high side.

We used to use a porta cool but like others mentioned it helped, but it also made it muggy after a period of time. So we gave that up.

My old shop would hit 120+. I ended up getting a portable ac and having it blow right up the back of my shirt while printing. Current shop is air conditioned, but by the end of the afternoon we still see temps in the mid 90s whem the flashes are going full bore. We cant really cross ventilate well though. My hope is in the next shop we can just open opposit sides and have a nice cross breeze...

Our shop reaches 115 this time of year.  We really change our staging so that we can have everything ready the night before so that we can hopefully be done printing by 10 in the morning.  We started at 4:30 this morning.  Every once in a while we get trapped into printing all day and that's a killer.   

Dirk, I'm right there with you as far as humidity in Southeast Arkansas.

I bite the bullet and use air on any days over 30* celsius and high humidity, found in the summer it may cost $150-$250 extra a month in electricity but is well worth the production numbers.

Today it's 93 here, I see some of you get much higher.
I don't know how you work like that.
For us this is an extreme day with a wind blowing off the desert.

During the summer months, we have tracked the heat between 100-130 degrees. (not even going to bring up humidity) It can be brutal, but you either learn to deal with it, or you don't. LOL

At the last shop I worked at on super hot days we would come in at 3 am and work 8 hours and out before the heat of the day!

We installed rows of fans throughout the building up top to help remove the heat. It definitely drops the temp by about 10 to 15 degrees.

105 with 75% humidity :(  1200 sq ft
That is with a big a** chicken house fan sucking the air out. In south Alabama it has been tough this last week, been dogging off printing by noon. Heck it is even hot when cleaning screens with the mist coming on you.

It's not how hot it is, it is how cool it is. 85f here.

This swamp cooler cooled shop here in las vegas has dropped 20 degrees since installing the sprint 3000's over the weekend

100-106 degrees, 30% humidity.

We''re still at the 100° plus, but, the hole is cut in the roof, the curb installed, and a 36" exhaust fan waiting for the crane to put it in place, then the electrical work. It should give us 10 complete air changes an hour.

They were in the initial search. In the end, since there is only one opening in the shop, at ground level, the fan is in the ceiling diagonally across, which was the best and most logical advice I could find. If we can get it done to 85° we'll be happy. I started in '75, Aug. 1, and it's always been hot and crazy humid in the Boston area in the summers, just part of the job.

This might be a bad idea, but what about a fan at floor level or ac blowing at floor level9 (window air that you can sit on the floor), I'm thinking if you get those feet cool the body might fellow, but then there is the dust and lint blowing from the floor?   Maybe a nice oscillating fan sitting in the middle of the press or some way attached to the press for the OP's,  I know you could put a floor fan under the dryer at the end of the belt, it would do two jobs keep the shirts cool and the unloader.  I'm lucky I have full ac throughout my shop, we find ourselves closing off some vents in the production area at times.

Same down here close to New Haven humidity is always a factor. Just because it is New England does not mean we do not get some crappy heat and humidity like other places. We actually broke 100 degrees outside temp a few times this year, add to the the high humidity ugh.

We are currently using floor based fans, and portable AC to blow on the printers and catchers. I suspect (or hoping at least) that our new exhaust will take care of the bulk of the heat. As it is, there is no way for heat to get out, so it builds "down" from the ceiling, so to speak.
