Re: AC not cooling



Photo of Deaerator? I think you forgot and please tell me where it is located.

And one thing a lot of people forget is that slower saltwater flow means lower heat exchange efficiency.

Thanks very much, Bill.  I‘ve pretty much followed the instructions regarding bleeding air from the manual but only one of my three chiller units has a valve to bleed air.   I’ve bled air from both the salt water pump and the circulation pump.  However, I believe I have a dearator- see pic.  Taking off the cap doesn’t do anything but if I stick a screwdriver into the top, turbulent water/air comes out.  

It seems to me that if the salt water circuit is working (it is - water is coming out normally), the compressor should be getting the temp lower than 28C.  So I think it‘s likely a low coolant situation.  The yard tried the system 3 months ago and it was working but not cooling much.  Again, this seems to point to low coolant.  

Again, many thanks for your thoughts!  Cheers Joerg
