A sight-glass on an evaporator is something that should be standard... It would make diagnosing what's going on with a T. X. valve that much more visual and help confirm empirical assessments (like, blockages and flooding issues) 💡
The behavior of the refrigerant foaming in the compressor is completely different than the boiling of refrigerant in the evaporator. What happens in the evaporator starts off very gradual and eventually becomes much more intense. Violent actually. Based on the parts you described, this is a standard system. What is magnetic about the compressor? It's bearings?
That looks and sounds like a screw compressor Trevor. By and far mag lev compressors are oil free. I'd be interested to see a picture of the compressoe nameplate because honestly I'm not buying what you are selling here.
@@RefrigerationMentor pretty typical for a vfd driven screw. Why does it have oil if there is magnetic bearings? The advantage of magnetic bearings is to avoid oil management and the efficiency losses associated with the insulating properties of oil.
Ah. The video title is misleading. They put magnets on the rotor to reduce slip during part load operation. It's a synchronous motor instead of a standard asynchronous. This is a normal screw with a different motor configuration. Franscold calls it a magnetic compressor...but it is not magnetic bearings. You may wish to change the title to be a bit more transparent. This isn't really a "magnetic compressor". "Frascold Magnetic series compressor" would clear things up. People will see this and possibly thing magnetic lev compressors have oil.
Thanks Trevor
Your welcome.

Yes thanks for sharing.

so there is no eev in this system? how? no pressure drop? sorry in advance for the stupid question, im still learning

Great Identification. You are correct it is a Frascold Magnetic Screw Compressor. What I thought was cool it can ramp from 60Hz to over 250 Hz

@@user-wn4el7gy2n Yea, was thinking the same when I saw the title.
@@user-wn4el7gy2n the majority of VSD driven refrigeration compressor screws do not ramp that high.
