Should have a receiver if you have a tx valve.
is it ok to charge walk in freezer to full sight glass . no receiver water cooled condenser

cycles on liquid line solinoid valve.compressor took a poop, was called to change out. copeland copelematic m. nrdi 031a tcf 800. going to change oil to ester before install. as well as ll drier and contactor. noticed someone has added suction drier canister with one core.no idea on history,not to familiar with low temp systems. thats why im asking about the charge.thanks
No receiver ??
Is this condenser indoor on top of freezer ?
You've got a receiver. Check under the condensing unit

Yeaa full sight glass is a good start but then after you notice the bubbles just starting to disappear, start doing SH and SC. You don't want to over charge..
Yeah, I bet there is a receiver under the unit.
I bet the condenser is also the receiver.
looks like discharge line off compressor goes to vessel under compressor then liquid line exits vessel to drier and sight glass then to evap to freezer. vessel has water line going into it with water regulater. regulator has cap tube that senses pressure via discharge port, then another line exiting vessel dumping water to open sight drain. dont see any receiver.
have picture on iphone not sure how to post sorry
so the reciever is the vessel and the condenser water is basicly a coil in the vessel condensing hot gas into liquid and storage before entering liquid line and so on..

From the description this sounds like a WJWL water-cooled condensing unit, which has a shell & tube condenser...referred to in the old days as a condenser/receiver.
The refrigerant flows through the shell and the water through the tubes so there a significant liquid storage capacity with these condensers. I found some specs which indicate that this unit would have a pumpdown capacity of about 42 lbs...not bad for a 3 HP unit.
Here's a drawing:

We have quite a few of these and I was always told to charge to clear the glass. Make sure your water regulating valve is set properly and it'll be all good.
Ice- our old timer calls them a "pump and dump" system. Have you guys ever heard that?
I suppose "Pump & Dump" originally got its name from back when many water-cooled refrigeration systems were of the open loop variety where either well water or city water cooling was a once-through process. For a lot of years now this has been simply too costly or outright prohibited, so most water-cooled units are on a closed loop setup with a cooling tower.
It reminds me of when my father installed a number of commercial A/C systems in New Hampshire using chilled water coils and city water...which came from wells and was a constant 50ºF all year round...and all it went to directly to the sewer. They worked pretty well actually. When they started metering the water usage in the 1960's, he got to install cooling towers or air-cooled condensers.
The Pump & Dump was popular a few years ago...but I'm starting to become a family man.
