Cap tube to txv?

[EugeneTheJeep]

I have done RI freezers a bunch of times with cap tube to TXV conversion. Just snip the 2 ends of the cap and leave it, run a piece of 1/4" along the suction, a little brazing and flare magic and you end up with a freezer that kick a$$ compared to the slow recovering crap tube freezer. No receiver required, put on a site and charge it till it clears. No more dead R-404A Coplematic compressors either.

With no receiver the refrigerant will back up into the condenser when there is no load. This has not been a problem for you ?
I like that crap tube analogy.

Don't know if this will help or not.....

So MT, how did your unit turn out?

X-2 on the Crap Tube. I like that a lot. LOL

Just wondering how others approach the controls. I could run low or line. It would be easiest to install a lpsw with nc to condenser unit. No defrost.

On the cap tube, I thought about what you said regarding the flooded condenser and I still wonder if one is taking a chance considering a tank is only a couple of extra bucks. Your right it would probably work just fine tho.

Under no load, why would you need full condenser capacity? A lot of OEMs are doing this with no receiver. No one has complained, and no compressors have failed, and the pull down time is just awesome compared to the crap tube system. The fan thermodisc starts the fan in only a few minutes, compared to 20+ minutes on the crap tube.

I still do not recall if I ever did this on a reach in medium temp though? But I would.

An over sized drier with the outlet pointed down makes a good reciever. Thats what many of the OEM's are doing.

I know some of the older hussman RI freezers use a txv and no reciever and they work just fine.

I am going to install a filter/drier anyway and I like the idea. I'll snap some pics when I'm done. I picked up the evap unit today. Had a little problem finding such a small tx. Sid harvey had a 1/4 ton that i think will suit just fine.

Here are pics of the install. I added a lpsw as a safety. Thanks for the input. Using the dryer as a receiver works great.
