Girish ji, I am again telling- You are genius. I couldn't understand why so poor viewership for such a fantastic and informative video. Helpful for supervisor to engineer. You deserve more.

[@tasdeeqahmad6012]

Nice sir

[@infinity4794]

Nice explanation sir. Sir I have a question. When the system run with 50% load, then 500gpm water will circulate in the cycle, but total system is 1000gpm; then rest 500gpm water where will stay and why they will be not circulate, who will control them? Please answer sir.

Two things i need to know what will be the pipe size of de coupler line if header pipe is 200mm and second thing where exactly dps need to be installed

[@Foodlover9339]

Sir last one I m quite confuse actually. 250 gpm water is coming from where ?? Once the 2nd ahu wich is off but the valve is open that one

[@infoall2876]

Pls prepare one vedio with complete valves connection in every interview asking this question

Sir kindly make a video on chillar safety parameters & referigent cycle pressure & temp

sir premary pump me lagta Hain vfd sir secondary me nhi

[@ganeshkamble6892]

Sir, Is there any motorised valve in de-coupler line which opens and closes as the flow requirement increases or decreases.

[@girishshinde]

I don't think

[@ganeshkamble6892]

@@girishshinde Ok Sir.

[@mujeeb7100]

Yes there is a motorised actuator which open and close the valve according to DPT , which gives the output on basis of 0-10 volts dc. And on this volts the valve modulates.

[@cad5273]

Not😊 required Motorized valve in Primary - Secondary Decoupler network, Flow meter can be added .( motorized valve is added for variable Primary pump circuit)

Sir,agar plant chal rha h us case me kya bypass line open hota h....agar hota h toh kya hot and cold water mix hota h...agar band karna h valve toh phir bypass dena ka kya matlab h??

[@mujeeb7100]

Usse manual handling nahi karte. Its total automatic control on basis of DPT . And by pass line has a motorised valve.
