please make some video on how to do maintenance of ahu fcu and chiller preventive maintenance thank for making these video it is very helpful for HVAC Engineer
Hi sir thank you very much for all your work it helps me very much. I have a question, how can I measure the flow rate of %80 water + %20 ethylene glycol (antifreeze) with an ultrasonic flowmeter
Question? for AHU to be properly working, in lay mans terns, does the flow of water through AHU coils have to be a faster flow rate or slower flow rate?
You will get a better heat transfer and thus better delta T (temperature difference) if its slower. If its too high the water will not change temperature as it flows through and so the chiller will operate inefficiently
What would cause low water flow to a chiller barrel? I had a site where they usually run one pump, but it seemed like they are having water flow issues. Now the chiller would stay running if they run two pumps
@theengineeringmindset can you please help me understand what the purpose of a Flowmeter is on a Turbocor Chiller? A system i worked on had a flowmeter but no flow switch. Does the flowmeter control the ramping up and down of the compressor based on flow rate? Why would a system like this not just have a simple flow switch? Thanks in advance.
The plate causes a restriction to the flow of water. In the direction of flow the water hitting the plate is at normal pipe pressure, as it passes through the plate the velocity increases, as velocity increases the pressure decreases.
The Engineering Mindset thanks mate .. you have been an amazing help. Is there any way to contact you about my problems? I am currently a mechanical engineering student and at the moment I am completing my project of the installation of central HVAC system in pharmaceutical company so the knowledge you share is kind of very much helpful to me
What is the name of provided chart with the chiller? We have currently bought 450 ton LG absorption chiller. I need to check is that chart available in the company.
The chart is not for a chiller but for the orifice plate. As I said in the video the chart is different for every orifice plate so you need to contact the manufacturer with the make and model nubmer

Thank you for sharing this for Chillers.

Most existing chill water systems don't have an Orifice plate how do you find the gpm with only delta P?
Very good and informative video on water balancing
In my case they put some pressuregauge to the inlet and exit water evaporator pipe , can i use both of these pressuse data to calculate the flowrate ?

You will get a better heat transfer and thus better delta T (temperature difference) if its slower. If its too high the water will not change temperature as it flows through and so the chiller will operate inefficiently
For chilled water pipe pressure leakage test, how many percent pressure leaks acceptable of the requirement pressure test?
Will there be an orifice plate in every cooling plant ?
Bro can you explain the water flow in both chilled and condenser water line,
Checkout our other videos, we've covered this multiple times
What manometer would you recommend for a field tech?
What would cause low water flow to a chiller barrel? I had a site where they usually run one pump, but it seemed like they are having water flow issues. Now the chiller would stay running if they run two pumps
The secondary and primary circuit, why do you need one more in between?
Check out our chiller terminology video and chilled water schematics video
Which one water have to use for chiller ?
Very useful video for us
If I have a variable speed pump, then I need a flow meter continuously records flow rate in order to calculate cooling load, am I right?
How to calculate refrigerant kw for ice plants
Loved your videos. waiting this video from long time,,,, thanks Buddy. really Helpfull :*
Hi, Paul
May I know when where the chilled water came from? Is the chiller produces it? How?
Everything is covered in our chiller series: theengineeringmindset.com/refrigeration/
Very very good excelant
but , How do we calculate Water flow rate through Chiller just by knowing Inlet and Outlet water pressures... ? Please guide me through this
Don't it's not accurate, measure it
@@EngineeringMindset I only have evaporator inlet and outlet pressure differential. Does your formula still apply?
@@EngineeringMindsetTrane factory engineers disagree with you
Thanks for your explanation but does the flowrate design for the Evaporator be the same flowrate for the Condenser in other to size the cooling tower?
No flow rates are different
Useful video ,thanks
AHU damper is fully closed then inside AHU motor is run or stop? pls explain

Thank u soo much for this video..
Thank you sir
Why do you think my Chiller temp is set for 17*. Then When the glycol temp reaches 17*, it starts to heat up. System will not hold temp
1 L/S = 3.6 M3/hr, so why did you divide by 36, what's calculation behind it
Thanks sir
Please tell about eductor.....
What is eductor in chiller...?
oil flows through it and creates a vacuum, this vacuum pulls in oil and refrigerant into the oil reserve
Thank q soo much
What does mean by low and high pressure side tubes In orifice plate??
The plate causes a restriction to the flow of water. In the direction of flow the water hitting the plate is at normal pipe pressure, as it passes through the plate the velocity increases, as velocity increases the pressure decreases.

I'm afraid I can't give individual advice I simply get too many messages a day, you can put the questions in the comments section though

What is kw for 8.5tr 3ph
v nice video...
thought the Square root of 6.2 is 12.4, how did you get 2.49?
Square root (√) of 6.2 is 2.49. You're doing 6.2 x 2 to get 12.4

Ok
