HVAC Tech School: Understanding Chiller Surge

[AGON]

This series of training videos is some of the best I’ve seen on YouTube for commercial hvac applications. Unfortunately there’s only a few videos published. There’s hundreds of videos on this channel but whoever this instructor is, I want to say thanks and please start a dedicated channel

Clear and easy approched explanation to amateur chiller sale like me. Thanks a lot!

[juanrobles]

The way he explains, makes it easy for me to understand the concept, thank you very much sir👍🏽

[skydyver]

Man I appreciate you so much 😢..this prepared me for a huge job❤

A very informative and useful video. Thanks a lot for sharing. Can you recommend a textbook for chiller maintenance and repairing?

[GlauberMGnoPR]

Thank you for your class! Watching in 2020 here! Regards

i might have this kind of problem. thank you for making a great video like this i learned a lot sir.. i Just have a question sir. my question is i have a water chiller with a screw type compressor and a evaporative condeser. im having hard time because the chiller always shutsdown due to high pressure. and when i open my evaporative condenser it has a water rust on the coils. is that the cause of high pressure on the plant? please answer my question sir i really need a peace of.advice.

that's exactly the same drawing of the refrigeration cycle of a chiller that I learned on too. great explanation too.

Very important understanding of surge.
And very nice explained

Very good video man, thanks for doing what you do!

Tim, I have an ammonia coolant system, where the ammonia leaves the condenser and goes up to the roof, where it is chilled and recycled back.  So, how do I determine the proper temperature of the return.  Plus, there isn't any leaf strainer which will cause ammonia to lead into the air.  Belts are working, fans are working,   I keep getting a surge that shutting off my pump, but the engineer in charge says that it's not the water tower.  what are your thoughts?

Absolutely fantastic explanation. Thank you so much this is extremely helpful.

Would you consider a groaning noise when the load is low a surge....

[marialuciaveraandrade]

Excelent video. I have a question about consecuences. Wich of the two tipes of chillers surge is more harmful for the chiller? thank you

[heidimule]

Fun, fun. I test chillers for a living. hot condenser creates a surge. If my unit surges I back off the vanes which lowers the temp in the condenser. A leak in the chiller that draws in air can create a surge. Or it can be just (in my case) bad test conditions. Watch the evap temp as this can bottom out in a surge. A surge is so loud that it sounds like a train.:)

Thank you so so much for helping me understand this!!

for water cooled chiller is a challenge time during high humidity . how can we manage the chiller to increase the header temp.

[trekdiaries_maharashtra]

Backward flow only happen in centrifugal compressor I think n not in screw compressor, pls confirm?
