This is how to make a refrigerant recovery pump from an old compressor the real ones cost $500 and up. You can’t release refrigerant into the air. How to wire the compressor new video Added a start switch • home made vacuum pump ...
Nice work man now you just need the certified stickers to stick on the discharge and charge areas to make it look official" so no mistakes happen down the road
You know you said you can't release refrigerant into the air..... I agree with this. BUT, every HVAC tech does it every time they connects gauges and recovers slash AC work. And all these new gasses "claim" to be safe for the atmosphere.
A pretty good video. You forgot to mention to purge the lines at the recovery tank and close off the Manifold High Pressure line not being used. However I learned enough to know how to build one now. I would also have liked to know what port you were tapping on the Refrigerator Compressor. Thanks so much for doing this video. Thumbs up! Best Wishes & Blessings. Keith Noneya
I made the same setup but trying to recover refrigerant compressor keeps locking up and trips the internal breaker. It can do vacuum perfectly goes to 30” and builds pressure over 450 psi. But when trying to recover refrigerant it shuts off.
Ya i think i need to make one of these i have a mini fridge that i punched the line inside that i haven't thrown away because i planed on pulling the compressor for something like this ir an air compressor
A compressor uses oil in the refrigerant for lubrication and the compressor will have limited life without oil. The object is to liquify the refrigerant and compressing it will make it hot. You need to cool the output to condense it to a liquid. You also need a filter-dryer before the compressor to protect and clean the compressor and make the refrigerant reusable.
is it possible to pump out compressor oil with this method? im thinking of ways to fully replace my car compressor oil without detaching compressor from the car, i heard vacuum pump wont pump the oil out 🤔
Good morning Yes I like the video but I would like to learn more about Refrigeration. I would like to build a setup like you have ok. Could you tell or show me where I can add freon in a refrigeration if I can do it myself & save money$💰too I'm calling from Houston TX. Oh keep up good video on here too
Hi. I have a question. Can i make a vacuum with this pump ? I not have a special pump to do this. I would like to suck all air from the system. I mean system in fridge of course. System in the fridge have fe pump, condenser, vaponiser, dryer filter, pipes, capillary tube and other elements. Thanks for help.
I know this is a few years old, but can you give me a source on where to get the Schrader valves of the size that will connect to the standard hose set used for residential AC units? I don't know what size/thread type are used. Thank you.
@@appliancerepair420 Thank you for the reply! You were right. 1/4 inch. I found Pack of (6) C&D Valve # CD3605-1/4" Access/Line Service Valve with 5/16" Copper Tube Extension so I only need to braze or silver solder the copper pipes together. I just need to find an old window AC to pull the compressor out of. I have a couple old non working refrigerators that that I use as fireworks storage lockers but I don't think those compressors would be large enough. They will run, just don't cool anymore so make a good sealed storage locker.
It needs to vacuum and gets rid of air in the pipe for blue, yellow, red, and compressor itself, at least. Otherwise, air is get into freon tank and pollutes pure freon in the tank. I recommend the commercial one, not your idea.
The bigger the compressor the mor suction power you have. This is meant for smaller appliances like refrigerators. You should use it on the same type of refrigerant that the compressor had example 134a because it might contaminate the pump and might go bad.
What type of capacitor was it that you used? What is it used for. Or is this just the start capacitor from the unit the compressor came from? Thank you and great video!
Ok so the blue goes to the the compre that is on the refrigerator. The yellow go’s to the the suction line of the homemade recovery pump. And the red would go from the discharge line on the homemade recovery pump to the recovery tank
The one on the left is the port to install the service valve for charging and to check pressures. The Smaller one (high side) is the discharge line that one pumps the refrigerant into the condenser. The fatter one in the back is the suction line (low side) it sucks the refrigerant back to the compressor from the evaporator. Hope this helps
@@appliancerepair420 suction port in the back or in Rt.side of the compressor where a yellow hose is attached.I think port in the back of first compressor simulate the source of gas from which you recover the frion but what it's function in the second compressor that you made as recovery machine?
