From Connecticut USA very useful videos thanks a million times

[@TechSystems]

Hi Armando I am glad to hear that.

[@MiddleBencher1989]

Thanks for sharing knowledge... Great work sir.. God bless you👍👍Love from India..

Super amazing dear brother, best and most favourite KZbin channel ever, very soon you will be number 1 on KZbin educational channels

[@TechSystems]

Thank you Brother.. Such comments keep me motivated.

Excellent!!! Wish I found this video a year ago. Subscribed.

[@TechSystems]

Glad to hear that it helped you.

@@TechSystems could you do some videos on water cooled chillers?

[@ramdoijad415]

Hi sir, Thank you for knowledgeable videos, your videos are really helpful, keep it up👍

[@TechSystems]

Thank you for your feedback 🙂

[@rasheedk.u8809]

Best presentation .Gold bless u . Can pls do a video on disticcooling system also . What is the difference . And delta t issues in the etc.

[@michaelbotha5431]

@techSystems - love the video, thank you. Just a question: At around 9:15 in the video, only 1 chiller is running due to low load conditions, but why not switch the accompanying pump off as well to save pumping energy costs? It is not necessary to run both pumps in this configuration with only 1 chiller running?

[@TechSystems]

Hi, This is a constant flow system with 3-way control valves at the AHUs and FCUs. So that's why both pumps needs to run to always maintain constant flow through system. Due to this drawback, this system is no longer used in the new buildings instead variable flow system is used with 2 way control valves.

[@basharsilawi]

Thank for this video..

[@SJEACEng]

Very good video. One question please after one chiller has been switched off, can we not switch off one pump also because load reduced to 50%?

[@marcchipping4397]

Hi @TechSystems thank you for the video. You mention in the video that the motorised butterfly valve is their to isolate the nonoperational chiller but in the video when the second chiller is off at low load the chiller is not isolated in order to maintain a constant flow at all times. Question - In what scenario would you isolate a chiller and what effect would the drop in volume have on the 3-port control valves downstream (e.g. in-balance, decrease in authority)?

[@sergiomarinmaldonado3993]

Thank you so much ! 🙏

[@TechSystems]

Welcome.

[@shahabajmullani9553]

Amazing explanation 👌👌👌

[@TechSystems]

Thanks

[@jarmenkell385]

Very informative video. Could you please make video about how chilled water pump speed controlled by differential pressure when there is high or low load, in secondary side pumping system.

[@kyleduesenberg3784]

These videos are very helpful. Thank you for making them. One question, in the one-chiller-off scenario, wouldn't the overall supply temperature to the building be 10.9°C?

[@kamamn4264]

Excellent

[@TechSystems]

Thank you

Amazing

[@hvacfaq351]

What is the point of the bypass valve, why not just use a flow switch?

[@omsaiproperty8843]

Chiller sequence /Auto / n series main nhi chal rha h toh kya fault hoga plzz explain guyzzz

[@TechSystems]

Was it working in Auto sequence previously? There can be many reasons. Might be the problem with DDC program

[@omsaiproperty8843]

@@TechSystems yes its working before I checked All CMS Panel N DDC panel bt no fault found i dont u derstand what is the issue ??

[@TechSystems]

It is really difficult to understand without physically troubleshooting it. There could be any possible interlock in control program which is inhibiting the system to operate or might be any issue from some field device signal. Sorry cannot help you with that.

[@omsaiproperty8843]

No wonder the ac here in this apartments are so hot 😫 they have this when everyone uses the ac it never cools down
