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

[@eulaliorodriguez5325]

Thank you for sharing this for Chillers.

[@mouhammadabdallahaw1131]

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

Very good and informative video on water balancing

[@90slove97]

Loved your videos. waiting this video from long time,,,, thanks Buddy. really Helpfull :*

[@stephaniehinkle826]

Most existing chill water systems don't have an Orifice plate how do you find the gpm with only delta P?

[@leylazafari692]

Very very good excelant

[@arinanta7994]

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 ?

[@BelizeTac]

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?

[@EngineeringMindset]

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

[@Razlazy227]

Very useful video for us

@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.

[@toyinorodare4072]

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?

[@EngineeringMindset]

No flow rates are different

[@timothy50506]

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?

Hi, Paul May I know when where the chilled water came from? Is the chiller produces it? How?

[@EngineeringMindset]

Everything is covered in our chiller series: theengineeringmindset.com/refrigeration/

[@jifri0120]

Bro can you explain the water flow in both chilled and condenser water line,

[@EngineeringMindset]

Checkout our other videos, we've covered this multiple times

[@amitchawathe9691]

Will there be an orifice plate in every cooling plant ?

[@SombraLocs]

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

[@khaleejkha4026]

Thanks sir

The secondary and primary circuit, why do you need one more in between?

but , How do we calculate Water flow rate through Chiller just by knowing Inlet and Outlet water pressures... ? Please guide me through this

[@EngineeringMindset]

Don't it's not accurate, measure it

What does mean by low and high pressure side tubes In orifice plate??

[@EngineeringMindset]

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.

[@syedsalmanahmed3877]

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

[@syedsalmanahmed3877]

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.

[@EngineeringMindset]

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

[@EngineeringMindset]

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

[@vigneshr5690]

1 L/S = 3.6 M3/hr, so why did you divide by 36, what's calculation behind it

[@derekreyes7487]

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

thought the Square root of 6.2 is 12.4, how did you get 2.49?

[@EngineeringMindset]

Square root (√) of 6.2 is 2.49. You're doing 6.2 x 2 to get 12.4
