I'm a newbie at this, so confirm if I'm thinking this through correctly. The flashing sight glass was because the faulty expansion valve was flooding the evaporator and suction line with liquid refrigerant. With too much refrigerant now on the suction side, the liquid line receiver ran low on refrigerant. Is this correct?
@joshuapellerito1341
5 жыл бұрын
That is correct. Most freezer TXVs are pressure limiting, so as the evaporator is flooded and the liquid refrigerant is flooding back to the compressor, it fills the suction line with refrigerant causing the system to appear long on charge when in fact its perfectly fine.

Sun ding liquid through the headers or scrolls can ruin a compressor as well. You want 100% gas going back through the compressor discharge. That’s why we take subcool and super-heat. Same goes the other way. If we have a sub-cool that is off with a flashing sight glass we are ruining the TXV since the TXV needs 100% liquid to work correctly. When gas goes though the TXV the valve body will jump more than needed to. It can destroy the TXV. Especially the way they are made these days.

Absolutely awesome videos and recaps. I been in the residential AC 5yrs When I worked with my old boss we did single evp and condensers. Recently got a lead to go see a customer. He had a parallel Hussmann cabinet. The guy who worked on it move so he says. Had 4 compressors. 1999. Only one compressor was working, he wanted a new and wanted to replace one compressor, 3 were bad. Customer gave me a hard time about adding freon, 55lb system 404A. It had 4 cases and one walkin chill box. But anyway. Do you have any videos on multi compressors systems or multi evp running off of one condenser. I couldnt find you email, the website wouldn't load

They get a second quote and that guy says the TXV is working fine, temp controller and solenoid are working fine, the contractor is dark but it working. So, the client doesn't want to spend a thousand bucks if he doesn't have to. If it keeps working what the client feels is fine then they assume you were wrong or trying to dip them off. A month to three later if it acts up again and the client uses garage logic and pegs you as an over do it sort of guy. How do you counteract client misjudgment like I just outlined above? My outline is a common occurrence in misjudgment around my part of the country.

You could always use your pinch off tool on the liquid line after the receiver outlet if you needed to change the drier. I bought one after doing a pressure switch on a Mani and have used it at least 15 times that year, mostly to weld taps onto reach ins while they’re running because the saddle taps are worthless
@44R0Ndin

I've seen one of HVACR VIDEOS vids where he used a saddle tap on a piece of equipment that didn't have service ports. I'm not a HVACR technician, but I do auto repair so I do have the occasional contact with vehicle AC systems. IMO, saddle taps should only ever be used to remove the charge from equipment that doesn't have service ports, and never left in place. That rubber you wrap around the pipe will degrade, and those screws are all that's compressing the rubber to seal it against the pipe, and a dirty pipe won't seal as well, and... well a leak is basically inevitable, and likely created when you install it. So it's best to use it as little as possible, and never left in the system as a permanent fitting. If I was working on something that didn't have service ports, and I needed access, I'd use a saddle tap. Once I was done, I'd recover the charge, then sweat in a pair of service ports. I don't like the idea of a pinch off tool on copper lines as it puts the copper thru so much stress that I'd never trust that section of pipe again (work hardening and micro cracking are likely at the corners of the pinched-off pipe). As far as I've seen from watching many videos, when I see a pinched off copper line it's also sweated shut. That's acceptable for long term use, but I only trust it because I've seen them that way from the factory. Even in plumbing saddle taps are a common source of water leaks, usually behind the fridge as some DIY'er decided that was the quick and cheap way to get a water line connected to the fridge's ice maker. The leak can happen any time from under a month to a couple years after installation, but it WILL eventually happen.

I’m not sure if it’s been mentioned in the above comments so i apologise if I’m repeating anyone else. The equaliser line is positioned incorrectly, when the valve & orifice are sized correctly (hopefully always) that will cause you problems every time. Obviously there is some liquid Cary over through the equalising line and when your bulb is positioned down circuit from that your creating a false superheat causing the valve to shat down equivalent initially then behave IRAtic with the fluxeration and what not.

The TXV acts as an adjusted gate and makes the refrigeration flow slow down, but the over-opened TXV causes too much flow into the evaporator coil, and the less liquid stores in the condenser coil, and thus, the over-speed liquid flow passing throw the evaporator coil ( the pressure can't drop to the ideal point), so it brings very low superheat, the saturated gas and liquid absorb the heat in the suction line, so you can see ice covering the line, and it could hurt the compressor very much.

Have a new WI Frz installed in NOV 2020. 2 weeks ago I got my first call saying box temp 20°. Bubbles in sight glass so I cleared it with 1lb 404. My diagnosis was that whoever installed it did not properly charge it and are just now seeing a problem due to higher ambient temps. I've done a leak check as well. Am I on the right track?

Why didn’t you check the sub cooling ?

Hello question, my country is mostly summer, I have two choices of TXV, one with 4 superheat and the next with 8, would the 4 produce cooler air at the evaporator than the 8?, It`s r134a

What size reefer wrench do you need for the TXV adjustment screw? Is it 3/16ths? Thanks for the videos.

If one of my guys had run that bulb like that he would be meeting me in that box! We would be discussing his career options!
