Title: Possible moisture issue
Post by: tim-bc on November 16, 2018, 02:00:57 AM
A facility that I was at today seems to have a bit of a moisture issue. The ground seems to be covered in water droplets as well as puddles in some parts.

Obviously I am not worried about a slip risk, but more about what kind of damage this could do to the miners or to the maintenance workers, since some of the puddles are near the breaker panels.

How much of an issue do you guys think that this moisture presents? Pics below.

Have you identified the source of the water?

The droplets suggest it might be condensing on the ceiling above and dropping down, or leaking through and flowing across the ceiling before dropping down.

The puddles suggest it's a decent amount of water or a separate issue of a leaky line nearby.

As long as the employees are wearing the electrical standards gear for the breaker sizes and the proper grounded footwear for smaller breakers they should be fine.

Either way I would be trying to identify the source of the moisture whether it be the intake air or a leak. If water is pooling and their is a good amount of airflow (which judging by the wall of miners there is) you probably have quite a bit of moisture in the air which isnt good for the miners

Edit: is that image of the exhaust side?

That's risky, and should definitely be fixed.

I would want to know where the moisture is coming from.  If it's due to a damp environment then an industrial air conditioning system will dry the air as well as cool it.  The heat from miners should take of the rest.

But yes, long term exposure to moist air will tarnish the PCBs, and could eventually damage them.

Do they have an exposed metal roof (internal and external) and cold outside causing condensation on the inside of the roof that is then dripping down? If the air inside is warm and the metal roof is cold - this could happen.

This doesn't seem like a BIT OF A MOISTURE ISSUE.  as it looks in the image a child can swim in there.  you need to figure out where it comes from, seems like a roof leakage to me.

Haha that’s exactly what my reaction was to those pictures. I’m trying to imagine an industrial environment where these conditions would be acceptable... I mean the floors alone, the owner is asking for a slip and fall liability issue. As for the machines, I wouldn’t even be comfortable touching them with that much water on them.

I’m shocked that equipment could still be functioning with condensation all over it.

The answer to this is actually very clear. Some of the seasoned miners and facility designers will agree to this... That room is simply too cool.. Condensation is being created where it shouldn't be. This is a prime example of a bad cooling design. This example is on the extreme end. On the lesser end, this is how/why people receive rusted fan guards on their miners after a hosting contract.

Well the average temperature in those cold aisles is 32c, and the systems were designed to maintain this temp whenever possible.

I do think the humidity might be a big factor though, since there is no climate filtering / evaporative cooling / whatever mining farms are using these days.

Interesting. Is it a 32c around the clock or do you have periods of degree changes in amounts greater than 10%?

I have 900 gallons of fish tanks. and my house is dry with a few miners.
that almost looks like your floor is not insulated, and is the cool point. you have humidity coming in from outside?
and it condenses on the coolest spot
the miners should dry that place out. it would seem you have a good source of humidity? whats the outside climate?

A thought just came to me. Is the outside temperature cold? If you have a sheet metal roof and you dont have insulation under it, condensation can build up on the ceiling if it is cold outside.

Apparently there is no filtering on the intake air, so when it rains I guess the water droplets just get sucked in by the wind.

Wow that's pretty extreme. I would even if temporary install some sort of hood over the intakes. This will at least minimize how much rainwater is being sucked in through the fans.

It's  pretty cheap and simple fix, especially when compared with damaging equipment. Margins are slim these days don't want to burn anything out through lack of effort.

You should have three things on your intake side. A weather hood is needed to prevent the rain pouring down. You will also need what's called a metal pre-filter or mist catcher so that the velocity of the air doesnt pull in water. The mist catcher is also good for humid climates. And then of course your regular paper filter after the pre-filter.
