This was an eBay find from years back. Was a sample from Embraco to Sundanzer; whoever they are/were. Has a large sight glass on the side. Will it work? Let's find out! Part 2: • Embraco Engineering Sa...
I was in electronics field in the Air Force and with GE. I worked for a few months with my Uncle as an early teen and he was in the refrigeration business. I've always had an interest. All of that said, I have learned more about refrigeration with your videos than I can believe.
Well this is extremely interesting, I love versions of devices with transparent windows to see them working. Another example is the WD Raptor X series of hard drives with a window on top, wish there were still things like that.
It is interesting to see inside things like this. I do remember the hard drives with the clear window! Then you put a clear case on your computer to display it.... and it displayed all the dust that built up inside the computer LOL!
Thanks! It does help carry heat from the motor to the outer shell of the compressor in spite of very low gas density in the housing. General Electric has one with forced-oil cooling of the whole winding! Have rebuilt one and will share videos on it eventually.
@@ElectromagneticVideos I posted that one yesterday, if you haven't seen it yet. Here is part 1: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-veH7sEMOAgA.html
It is easy to clog thins with it, but when joining dissimilar metals, sometimes nothing else will work. Also, practice makes for better results. It is a more advanced product to learn to use versus Silfos, but it allows otherwise impossible repairs.
You can also see that the gas in the oil only comes out of solution when there is a sharp corner to act as nucleation point, with most of it being only at the sharp edge of the window mount, where there is a sharp edge in the steel.
@@chrisingle5839 Yep, GE also did that, although with a different mechanism. Demonstrated that much to the detriment of my floor and clothes on my CG compressor rebuild video.
Cap tubes suck for anything that wasn't specifically engineered for it. Like you said, it's a balancing act, a guessing game. And you have to hope it never loses charge because it'll throw that balance off. My home's central air was a cap tube system. Dumb crap. Didn't even know they did that, guessing it was from the 1980s. The common metering system is a 'piston' which really is just a selected orifice size, which you also have to guess. Also dumb. The cap tube system worked right for a while after I recharged it - purely by luck. I didn't even know it was a cap tube system at the time. It leaked a bit and after that I could never get the charge level right, either too much or too little. I cut the bs and put a thermostatic expansion valve. Working perfectly for like three seasons now. I also put a sight glass and service valves indoors. Not that I'm saying you should do that here, just rambling about how I hate cap tubes :)
They made piston systems up until recently. Plenty of R410A systems running a piston. You have to charge them by target super heat. Royal pain compared to TXV.
Thanks for your detailed comment! Cap tubes are frustrating, because no matter how many details you put into the engineering of the system, there is always some trial and error. Then, after the fact; you have varying ambient conditions thrown into the mix as well! The trade-off is simplicity, ease of manufacturing, and guaranteed system equalization. All the things manufacturers care about LOL! My home still has its original R22 central air, with orifice piston metering. Still has an old reciprocating Copeland compressor. When I first moved in , it had a 5 year leak which I was able to locate and repair by pure luck. Hope to keep it forever, since the newer stuff is so cheaply made with thin wall tubing and coils, and too much electronic nonsense to fail. I've hoarded enough R22 for several charges; as well as have other spare parts squirreled away. One place cap tubes are definitely out of place is belt-drive systems. That is because these always slowly lose charge at the shaft seal and you need a system with reserve capacity and a design which will not change in performance over a wide range or charge levels. Some makers did this, and their systems were very high maintenance. I have been installing oversize liquid receivers and TXV metering on these. Much less hassle. Now that it is so hard to get any older systems, especially belt-drives, worked on - it needs to go as long as possible between recharging. That is because of the hassle and cost associated with getting it to a specialist when that becomes necessary.
saw a GE monitor top in what looked like really good condition (crappy pics) supposedly working, on marketplace in southwest florida for $150 if you have any contacts down there
@@davida1hiwaaynet I'm not, your videos are the only place I normally see them! I do my fair share of refrigeration experiments but mostly just my house and vehicles. Hopefully someone good finds it. They had supposedly listed it for $650 and dropped it to $150. Been for sale for a long time it said. Figured $150 was cheap without knowing what they normally sell for. I mostly buy tractors on there
@@RickBaconsAdventures You really won't go wrong for $150 on that Monitor Top, unless it is rusted out or has some other major and difficult to fix flaw. As for the Monitor Top forum, it is here: monitortop.freeforums.net/ Myself and the other admins and members would be happy for you to join!
Hey,off topic but can i build a mini air conditioner with a small mini fridge comprossor but not pull a vacuum on the system? Will it still work? Dont have the cash for a vac pump
