cool liquid line
cool liquid line from condenser on 404 static coil freezer with head master valve. sea water cooled condenser. 2 ton system, any thoughts? thanks d.d.

1. Over Charging ?????????
2. System partial Chock ?????
Thanks

Re: cool liquid line
Too much sea water flow through condenser.
System turned off
Blocked filter/drier.
I'd be looking to see what temperatures and pressures its running at and compare these to what i would expect to see.

Re: cool liquid line
new condenser. new drier, new valve, new piping, pressure 200 and 05. box at 0 .

Re: cool liquid line
Do you have a problem, or have you just got sub cooled liquid?

Re: cool liquid line
You are running with a headmaster valve, which is designed to maintain head pressure by reducing condensor size (through occupying parts of the condensor with liquid refrigerant)
assuming low condensor cooling water temperature, condensor will be well flooded
By the time the refrigerant exits the condensor it will be very subcooled.

Re: cool liquid line
please let us know the temperatures of cooling water inlet to condenser, and outlet.
Pressure at suction and discharge so that we can find the corresponding temperatures for R404
It appears the low ambient may be cause or the system overcharged, but if it is overcharged both suction and discharge pressures will be high.

Re: cool liquid line
Is the liquid line sweating ? If yes , partial blockage resulting in pressure drop & fall in temperature whereby liquid line is cool .
Or else measure refrigerant outlet temp at condenser outlet & liquid line temp . Note the difference ; a difference of 3 to 5 k would be sub-cooling . Hence to stop further guess work , it would be appropriate to measure temps.
