HVAC Chiller Approach Explained

This hvac training videos goal is to teach hvac technician on how chiller approach works and what to do with it. I give an indepth look at condenser approach and evaporator approach. This online chiller training is great for entry level chiller tech looking to expand their knowledge. This applies to water cooled chiller and air cooled chiller. This can also help with centrifugal chiller surge. Chiller surging is commonly a heat exchanger issue.

Best commercial hvac channel on youtube

Great Video Holden! I like the last part especially! All the money and recognition in the world means nothing without a family that cares about you.

[andrewedis]

Im from the UK and I don't see thses very often so thankyou for the video.

[therealmcgoy]

One of the few channels on chillers that is in depth and informative. Thanks! I have six chillers at work. They are a mystery but I have to work with them.

[dodgerblueable]

Excellent description of approach. When I was an apprentice, a journeyman tried to tell me the delta T between incoming and leaving water was the approach. I spent a couple years believing that, lol!

[davidwilliams]

Thank you for helping me understand chillers.

[jasonjohnsonHVAC]

Approach can be used on any piece of equipment with a compressor attached to it. I remember when i was in didn't put subcooling numbers they used approach. Its a good metric, along with discharge superheat

[nickyengle]

Liking your videos btw, wish we had this 30 yrs ago.

[joshstevens]

I really like that u r trying to get young guys interested in large tonnage machines. Im the youngest chiller mechanic that we have and im 40. Our vets are retiring this year

A SOLID MOMENT IN HISTORY KEEP UP THE GOOD WORK.

[Astrojamus]

can i just say thank you I just got the building engineer position and I came from hvac background and I have enough knowledge to be able to get by but I never got to diagnosing the big boy stuff. I hate when I look up explanations and its a video of a tonka truck dropping off and picking up hot/cold water its like dude i want to know exactly what's going on in that tank so i can understand!!!

Great video and commentary on the reasons we pay attention to approach. Particularly found useful your commentary on adjusting water flow rates and the impacts of these adjustments

[jweschler]

Very good video. I’d like to add that the reason the approach goes up when the water flow is too low is because the water will go into laminar flow (as opposed to turbulent flow). Laminar flow is when the flow is so low that the water flows down the center of the tubes and is stationary on the tube edge where the heat transfer is taking place. Think of a small stream with very low flow. You’ll see the water and leaves flowing down the center and the water is stagnant on the sides. Turbulent flow has all the water mixing up going through the tubes. In a chiller, when you approach laminar flow, you loose you’re approach very quickly.

so gret learning chillers fanda thank s sir

[AKK]

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

[vrejbaghoomian]

Hi, I have 3 "Carrier 5H80" compressors in tandem configuration, besides the oil equalizers on hand hole lower connection, there is also piping on the same hand hole on upper hole which are connected to all 3 compressors, do you know what is it for ?

[pridemechanical]

Can you recommend any good chiller classes given by manufacturers to help us build a chillers division?

[politiciansthrowstones]

Is that bottom on the hybrid the subcooler? Is there a subcooler on the flooded barrel?

[hkhsm]

Nice video.
Great knowledge.
Thanks for sharing

[MrEric]

Fantastic explanation as usual. Keep up the great work!
