Hey guys, I'm afraid we got ripped off on our glycol chiller.
We've got a 8 hp Copeland scroll compressor (ZR94KC-TF5-450), a reserve tank that's got a capacity of around 1000 liters, plus around 218 liters of cooling liquid in the tubing.
The glycol unit was assembled by a guy who I found out (after the purchase) has a bad reputation and I am looking for a sanity check that this is the right type of compressor to do the job. I understand that the unit's horsepower is good enough for my thermal load of 50,000 BTUs, my concern and question is this the right type of compressor. Another refrigeration guy told me that this compressor is hermetic and that a semi-hermetic would do the job much more efficiently.
The system frequently feels like it's fighting to keep the temps down.
What kind of trade offs am I looking at in what I have vs a semi-hermetic unit?
