I think you need the pictures saved in a jpg format on your computer, then you can copy, paste, it in, or paste a file path to the pics...

...but sometimes it just doesn't work..in that case you need to make a visual representation, or describe it in detail...

The best and cheapest way to cool an unconditioned space as far as I know is with a fan and mist...

Unbelievable--- I just can't.

Already have jpeg......

Not copy-paste... no file path....

I made it at once.. but don't remember how

I'll think how to explain this idea,

Thank you SolarEagle

Just like that....

But, instead of to be a courtyard... it is a little factory

The fans are located at the wall... instead of to use a fog as cooler... the idea is to use aluminium pipes in front of the fan, filled with cold water, coming from a freezer.

So then you must determine the BTU need as in heat load, and the cooling BTU's available, in any case the little factory must be sealed and insulated to get any worthwhile cooling...

You can ballpark it at around 2400 cubic feet per ton of cooling demand, or 12,000 BTU's, if the space is properly air tight and insulated with preferably R-30 grade equivalent...

Your water to air heat exchanger...air flow should be about 400 cfm per ton of cooling...

You want an air temperature drop of at least 16° F across the coil, your water temperature should be around 35°F input maintained...and gain around 10°F across the coil...

You'll need to acquire or fabricate the duct, drain pan, and a blower for air delivery...

Using existing fan with just pipes in front will restrict the air too much and fail to exchange heat properly...You need a separate system for cooling...

None of us can post pictures reliably anymore: sometimes one method works; sometimes another, and, sometimes no method works.

What you're describing is close to the way an air conditioning system works; except that you are adding some unnecessary stages.

An A/C unit uses a compressor and a couple of blowers and finned heat-sink/sources to move heat from one place to another. A freezer does the same thing. You want to add an additional stage to transfer heat from the workshop to the inside of the freezer.

So unless the freezers and power for them are free, a traditional A/C unit is much more economical.

Maybe you can find a car radiator to pump cold water through, with a good fan behind it. It is already designed with fins to efficiently transfer heat from coolant to an air stream. It will work the other way as well.

Just a thought...

The fan would have to be in the front of the radiator, the radiator needs to be under negative air pressure to flow correctly...

You could just run the cold water to a pull chain shower centrally located in the shop for a quick cool down from the waist up as needed...10 or 20 seconds should do it....
