Please, please, please do a video on low loss headers and hydraulic separation in commercial heating systems. I promise to buy you a coffee if you do. Thanks.
Most purgers use high pressure liquid ammonia and an expansion valve to condense the ammonia in the foul gas off the top of the HPR if I’m not mistaken. I usually deal with Hansen purgers and have even seen one on a Frick 150 ton screw package running on R22 serving a spiral freezer. Great video though! Cool seeing what other equipment is out there! Do you know what Danfoss does to avoid corrosion of the piping in the purger refrigeration circuit? Is the evaporator coil stainless or steel?
My question is how do these gasses get into the system? and what rate, we talking purging a tiny tiny amount out every month or we talking this is a 24h operation?
Hi Simon, it's going to result from leaks, service work and chemical reactions so each system is different. This unit runs and monitors the system 24/7 and utilizing control algorithms developed by Danfoss, the controller determines when the collected air is pure enough to open the discharge solenoid valve.
In industrial systems, suction pressure might be set to around -0,2bar to reach a colder temperature in the evaperator, hence increasing the efficiency. This has the unfortunate side-effect of sucking in air in the cold side of the system. Although a system is tested to be completely sealed with positive pressures, that might not be the case with negative pressure. An air purger is often the solution
hi...my question is that if we have no solinide valve or seprate system for purging as shown in video then what is method....? we just have a valve for purging manually
What's the benefit of Danfoss using a separate refrigerant system in their purger? Hansen and Parker models use HPL ammonia and house suction to cool the discharge gas & non-condensables.
⚠️ *Found this video super useful?* Buy Paul a coffee to say thanks: ☕

Well this just made my monday morning a little bit more enjoyable, thank you Paul!
Thank you and glad to hear
Blessed are we, for we are graced with another engineering video from the Paul.
Prophet Paul 🙌
Plenty more to come too!

I always amaze of all your education videos... Thanks for the ideas that you share ❤️
Thank you for the excellent explanation with diagrams! 👍
You're welcome, enjoy
Thank you for sharing this video.

Nice explanation with diagrams.
Very good demonstration. Would appreciate if U cover Automotive HVAC system as well ,Since most of the people would be needing this.
Great suggestion, I'll add it to the list
@@EngineeringMindset Thankyou & Looking forward to it.
I would love to see a video on flushing of an LTHW and CHW system and back flushing of an AHU
Thank you very much
Nice work 👏👏
excellent!!!!
What is the difference between the compressor rotating 3000 rpm/d? And 1500 rpm?
How does any air get into the system in the first place?
another great video.
Thank you.
Please tell about central ac

Why on the reciever in this video, is there only one pipe going by the reciever and not in and out like the video on single stage
These ammonia units are used where and what applications?

Nice!
Thank you
Hey paul, when the video about diesel generator+alternator+avr will launch? Thank you
Hey, probably Dec/Jan, we have a lot of video's coming in the next weeks on electrical
Check out how car alternators generate electricity here: th-cam.com/video/jdSKlg80DjU/w-d-xo.html
Is it available in India 🇮🇳?
Thank you, do you know we also have a Hindi channel? th-cam.com/channels/g4k338hz9U8jnD5SXPO5jQ.html
