There are alot of pertinent information that you guys are leaving out. Most technicians or bldg engineers will get confused, if they are not familiar with the function of a chiller plant design. How can I get a job with Higgins? Iam York and Trane Certified
So the pumping scheme is a primary pump system, three pumps all together and one serve as a backup for both chiller pump. Is this a LOAD BASE SYSTEM? OR A FLOW BASED SYSTEM? WHAT TYPE OF CONTROL VALVES ARE YOU USING ON YOUR AHU'S? TWO-WAY OR THREE-WAY? THE 3 WAY VALVES ARE FLOW BASED, AND THE 2 WAY VALVES ARE LOAD BASED
I don't see the flow switch on The main chilled water header. Did you put a check valve on the rise because often times there is a back flow during pump change or a power glitch and that backward flow trigger the flow switch, causing the chiller to trip and go offline
I have two questions, what's the pumping scheme? Primary only or primary and secondary? Is the chilled water header design a direct return or reverse return? What's your delta T on this system 10°F 12°F or 14°F?
Very interesting and very well explained including instruction.
Dear respected sir/mam ,that’s videos about going to be glorious to be an inspiration of hvac:::
Picked up quite a few fact nuggets in this vid; nice job.

Best job
For clear cut information please share the p&id and with pdf drawings it was nice video

THE 3 WAY VALVES ARE FLOW BASED, AND THE 2 WAY VALVES ARE LOAD BASED
Thats pretty well described.
Great job there.
I want to see him operate the plant (steam/chiller operating) on a emergency scenario. Haha
Yoir main headers seem like 12"-14" or better in diameter. That's alot of flow on the chilled water supply and return pipes
sir good job ...add maintenance and operating chiller
great great great video for the novice and advance skills engineer

So this is a Hospital because he mentioned having the plate and frame heat exchanger that cools the MRI UNITS= MAGNETIC RESONANT IMAGE MACHINE
Great presentation
So where is the clinical air and clinical vacuum? It has to be in the mechanical room (engine room)
He knows what he's talking about
could you please explain the hookup for supply & discharge lines showing the recommended distances between the installed fittings thanks ..
My tower is a baby compare to the one on this video, but basically same operation and concept.

All the piping, maintenance, and water treatment, is it really more energy efficient than some condenser fans?
WHAT BRAND are the chillers? YORK? UNIT COLOR IS GREEN, SO IT MUST BE YORK
Ohh yeah, it is very good.
Excellent video, also how did y'all get Le Chiffre from the new James Bond movies? Lol!
Can you explains Sir , why primary or secondary or both pumps are VFD controlled.
Question do you have a flow switch for each chiller? or do you have a common flow switch for both chillers?
How can I get a job with Higgins
What's the GPM on the Chilledcwater CKT?
How could air flow loading calculations
fine
Is this the hospital that kidnbapped the little girl for a year??
+BTraine Ztraine Yes, she was hidden in the cooling tower.
What language is he speaking French? Lol
