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.
Nice sir
Very good sir
Keep watching
Very nice explanation Sir 🙏🙏
Sir, great video
ek number explanation!
Great explanation
# SAWAL...sir car parking ventilation, basement ventilation and lift, toilet ventilation kaise kerte hai aur iski working kya hai plzz new video. Md Minhaz Ahmad..from Sitamarhi Bihar
Very funtastic video ... 👌
Thanks Sir
Bahoot bahoot sukhriya Girish
Please make one video for is about the function of pressure safety and how it works like oil failure's switch how it works I need all the details of pressure safety switches
Ok Sir
Nice video.
Sir I request you to please share the pump head calculation video
𝐓𝐮𝐡𝐦𝐢 𝐞𝐱𝐩𝐥𝐚𝐢𝐧 𝐤𝐡𝐮𝐩 𝐜𝐡𝐚𝐚𝐧 karta👌👌👌
Thanks
Nice explanation
Thanks
Pls prepare one vedio with complete valves connection in every interview asking this question
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
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
Sir kindly make a video on chillar safety parameters & referigent cycle pressure & temp
Thank you sir
Welcome
👌👌👌
Thanks Sir
Thanks sir 👍
Welcome
Salut sir
Sir, 750GPM case mai ager pani D coupler line se pani wapas reverse jata hai to us pani ka temperature kitna honga.
Low delta T hone k Kya Kya kaaran ho skta hai ispey vedio bnaeeye sir
nice
Thanks
sir premary pump me lagta Hain vfd sir secondary me nhi
Sir, Is there any motorised valve in de-coupler line which opens and closes as the flow requirement increases or decreases.
I don't think
@@girishshinde Ok Sir.
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.
Not😊 required Motorized valve in Primary - Secondary Decoupler network, Flow meter can be added .( motorized valve is added for variable Primary pump circuit)
De coupler line me NRV Hoga to water 2sides kaise flow karega.
Ntv hota hai kya?
@@girishshinde NRV Non return valve
Nrv pump outlet m hota hai
Sir ahu ke aage Jo Valve hai WO requirements ke according open hota hai kya
Yes
Sir, lekin ye bataye bypass line agar open hoga toh kyo hot water or cold water mix nhi hoga
Hota hai
@@girishshinde yes sir phir cooling par effect hoga....sir why we giving bypass line....iska benefit kya h
Sir is me cooling tower ki jarurat nahi hoti kya
Cooling tower condenser side main aata hai
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??
Usse manual handling nahi karte. Its total automatic control on basis of DPT . And by pass line has a motorised valve.
But some projects, we use variable primary pumps also
Yes
@@girishshinde can you make vedio on this variable primary pumps like where we use it for small project or big ptoject
Sir Ahu ka coil tempture kitna hota hai
15to18
How to work decouplers actuator valve where you get signal where you fix differential pressure switch
Actuator chiler retan supply ahu in retand actuater open reculin out ..
De coupler line me NRV Hoga to water return kaise Jaye ha
De coupler line mai NRV nhi lag tha
@@fathmasameer7523 to phir 2side open rehta kya
@@javeedhvactechnician7760 yes brother
Sir primary pump me water kaha se leta hai mr.shinde Sir cooling towar ke sath diagram bataeye
Sir g keya haal hy af ka
Awr sir g chiller acha chlta hy awr achnik anloding ho jata hy aska kya waja ho skta hy demaand be hota hy
Awr sir g afka mobil nimbr dyskty ho
Condensor se jo colling tower se condensor me aata h
Expansion tank se letaa hai
