RTU's not cooling the building enough

I know this is going to elicit a number of negative comments, buy I've seen water sprinklers wetting the coils to get thru extreme conditions.

We actually have sprinklers set up in 3 of our units right now. We try everything to reduce heat inside.

is the returns ducted from the space back up to the rooftop or egg crated tiles pulling the ceiling heat back?

Yeah, the returns are ducted back to the roof toop.

Excessive use of city water to cool the coils will RUIN your condenser coils.

Actually no, Sixer. The point was that he wondered if he needed to units and that he was unsure if the contractor did a proper load measurement. Sorry, was trying to help out, knowing he is in the area.

And thanks for sarcasm. Must be the heat.

Run those units 24/7. catch the load early and you should help slide by the 3pm heat hump.

And close the OA dampers. completely.

You need more condenser capacity. If using the city water is not a big issue, you may be able to get small water cooled condensers installed in the unit. Will take some ingenuity, but use that as a supplement when conditions are above design. As mentioned, city water can destroy a fin-tube coil.

Who are you thanking for the free advertizing ?

New units as a solution to high temporary load ? You guys do residential too ?

I was responding to his post. And if you read his post it said they will have to get a new unit soon. So that is what I was referring to. Sorry that this post ruined your day!

I was thinking the same thing, but it's a nursing home, so they probably run them 24/7 already.

We are actually a nursing home facility ...

Be careful what you post about your situation in an open forum. If someone expires due to heat or dehydration, you might make the news, or worse.

Doesn't effect me a bit. Its just unusual.

Other guys offer up advice and warnings on this forum on a daily basis. Your advice cost $$$$.

People come here to get away from the used car salesman that infect our industry with less than honorable sales tactics.

To get a second opinion from techs who donate their time and knowledge because they suspect somethings not right with their equipment or the way they've been treated.



This forum is an amazing concept that acts like a antibiotic to all of the dishonest techs and hack workmanship that plagues our industry.

Not saying you're one of those people either so dont misunderstand.
