Tower water temps
Looking for a little chiller help... I have a Carrier 30HR050-B150 with water IN from the tower at 110 degrees and leaving the chiller at 122 degrees. The outside temp was 98 yesterday. How much of a delta should I expect to see? The water leaving the chiller was only 52 degrees.

Why was your tower water so hot should be about 85 or so?

It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

I'm thinking something is restricting water flow or a weak pump, I really have no way of determining GPM

Your delta T is not too bad could be alittle better but your condenser water loop is not transfering much heat from what I can tell.

Whow! Tower loop is way way way too hot. You need to confirm the tower and tower fan are in good working order before you do anything else. Then check your pumps, pull strainers, check circuit setters, and lastly condenser barrel water pressure controls if you have them.
I suspect you either have flow issues or your tower fan is not working.UA LU189
10mm, because it's better than .45acp

Yes it would in my opinion. Does there appear to be a sufficient flow in the tower ? Originally Posted by air2spare

You need the PD across the heatexchanger. Then you will have to know the performance curve for that model chiller .At least that is how I do it other people may have a better way of doing it.
Ifyou shoot me a M# I will try to find something on it.UA 100

What kind of tower do you have? Is water going over the top of the tower? Or maybe running through a bypass? Hot deck plugged up? 110*h20 pretty darn hot. Not to sound like an a$$ but is the fan going the right direction?

"Lots of algae" will cause the tower not to make capacity. Based on rule of thumb, your condenser delta T looks good (should go down when problem is corrected) assuming you're at full load, but you're not removing the heat from the cooling water. Your tower ain't makin' capacity......
