Perfectly Described. Highly appreciated and thanks for your time and efforts. Acha ye batao vrv outdoor unit se ahu ko jo refrigerants pipe jaati hai na uspe motorized valve and temperature sensor lagte hain kya?
Acha 3 way valve mn ap ny btaya ki jab temperature ki requirmint pory ho jye gy to water bypas sy hy return mn chala jye ga wo kesy strainer ky agy to koi valve nahi hy na bechy koi valve hy to pani bypas sy kesy return mn jye ga
It's not cumplosory to install 2 - way and 3-way valve in return line it can be used in supply line also operation will be same without impacting other parameters
2 Way control Valve only on return line to stop and hold the chilled water in AHU for a certain time for achieve required cooling. then 2 way valve regulates and let go water... hope this helps to clear your doubt.
In Bypass we commonly use gate valve below 50 MM and butterfly valve above 50 MM which is use for chilled water flushing purpose. And for equipment back flushing we use drain cocks provided in supply line.
To allow proper flow of water in HVAC chilled water pipe Circuit setters feature a built-in balancing valve system and measuring points allowing for automatic calibration of the water system.
reyaz Ahmad Once the room temperature is met, the chilled water flow is bypassed completely for a 3 way Valve, while the flow stops completely in a 2 way Valve
reyaz Ahmad depend karta hay k kis position Mai install Kiya hay 3 way valve, Usually normal condition Mai 3 way valve chilled water supply Kar raha hota hay or by pass off hota hay
Could you pls explain the application of bypass line which is above the 2 way and 3 way valve as shown in both cases ? How does this valves is operated and is it connected to the thermostat?
The purpose of a 3-way control valve is to shut off water flow in one pipe while opening water flow in another pipe, to mix water from two different pipes into one pipe, or to separate water from one pipe into two different pipes.
2Way Valve: 2Way (Or2 Ports) Valve is passing the water in one direction only. so if the valve is fully close it will trap the water before it. this will lead to a pressure increase in this branch. Way Valve: 3Way (Or3 ports) Valve is passing the water in2 directions. so if the valve is fully open the full amount of water will be moving in one direction, if it closed the water will pass to the other direction, if the valve is partially open then percent of the water will flow through direction1 and the remaining will pass through the other (for Diverting Valve which installed in the supply line). In another cases if we install the valve in the return line so if the valve is open water will flow through the unit (Cooling coil as example) then pass through main direction. if the valve is close the water will by pass the unit and then flow through the other direction through the valve (Mixing Valve which installed in the Return line). this will not cause the pressure rising.
I already understand the applicant of 2 & 3 way valves by your video. But my question is different. I will explain you clear, their is a line which is also redirecting the flow to 2 way valve, you are calling it as by pass line. What is this happening ??
What is the use of 2 way and 3 way valves in piping What is the use of bypass valve in the chilled water system What is the use of actuator in HVAC Explain me in short sentence or in a small example
Your video is very informative sir.thankyou for uploading such type of video
Welcome. It's good to be helpful 😌
I always had a slight confusion in these but know its more clear.thank u
Excellent vidio, bahut accha samjhaya, sir thank you.
welcome Raqeeb
Great work
Thanks sir good explanation my god bless you
Thank you so much
Good explanation. Thank you for sharing
Welcome Anthony 😊
Very good explanation sir , We expect more from you 👍👍
Oh honey your teaching is very well
Be specific,don't repeat ,come to the point ,it's installed in return line,once temperature is reached it shuts off
Good explaination sir thank you very much
Good information
Thanks very informative video
Good job sir
Perfectly Described.
Highly appreciated and thanks for your time and efforts.
Acha ye batao vrv outdoor unit se ahu ko jo refrigerants pipe jaati hai na uspe motorized valve and temperature sensor lagte hain kya?
Well explained sir
Thank You 😊
good..informative..
Nice explaine. Super.👍
I have one doubt. Why control valve is always used in return line, not in supply line.
would be good if there are english subtitles, great video nonetheless!
Thank you sir
W done
Nice sir
Thank uu
Sir star video on hvac drafting, like how to draw duct, fcu ahu like in simple drafting
Can you translate to english?
Two way valve flow through a to b or b to a
Sir i have a actuator installed with fcu. when i turn on .the unit once actuator goes on but after few second turn automatically. What's reson?
Sir thank you very much , can you please share catalogue & diff make of valve for us
were do we fix vsd pumps pls do one video sir
👍👍👍
Why drv is used in bypass line. Already have on return line after the three way. Please explain it.
Sir, jo return line me bypass valve laga rakha h fir usska use hoga, jabb aap alag se bypass line bana rahe h, 3 way valve k case me.
Acha 3 way valve mn ap ny btaya ki jab temperature ki requirmint pory ho jye gy to water bypas sy hy return mn chala jye ga wo kesy strainer ky agy to koi valve nahi hy na bechy koi valve hy to pani bypas sy kesy return mn jye ga
You mean actuator send command to pumps.....how?
What is Local air conditioning system?
What is centralised air conditioning?
sir valve only can connect return line
What is the purpose of using using 2- way and 3-way valve in the return side of chilled water pipe.
Why cant we install in chilled water supply pipe.
Mohammad ABDUL QAYYUM the purpose of pressure regulating to increase cooling effectiveness... ensuring coil was running without CHW
It's not cumplosory to install 2 - way and 3-way valve in return line it can be used in supply line also operation will be same without impacting other parameters
CFM aur apporoach kaise nikalte sir
Sir what is riser in HVAC?
Riser is nothing but it is a panel in which return air connection given to that panel at top of it
Sir acturmoter kis line me use kerte hai
Is this valve is a replacement for DRV?? and this will be only in the Chilled water Return line
??
muhammed arshak DRV is different Actuator is different 2 way 3 way valve was like actuator.. DRV was installing purpose of balancing
Hello sir ye cantrol valve ko chek kaise karte hai ye kam kar raha hai ya nahi reply sir
Are bhai supply line pe kab se lgne lga
Sir hot gas bypass valve Selec karne ke liye bataiye na
Pls give lec on hvac classes
how we calculate pipe size with respect to gpm
Why valve arrangement in return line only can u explain this
What if i fix the valve in supply line?
2 Way control Valve only on return line to stop and hold the chilled water in AHU for a certain time for achieve required cooling. then 2 way valve regulates and let go water... hope this helps to clear your doubt.
2 way valve ho to fcu ko band kry gy to wo close ho jye ga or water return nahi Ho ga
Hello Ali, if there is no cooling Requirirement and FCU stops then due the signal from the DPS will be sent to the VFD Pump to reduce the demand.
Sare lecture k PDF file v upload Kar Diya karo sir
OK sure. Will do that.
Can we install gate valve instead of balancing valve in the bypass line?
In Bypass we commonly use gate valve below 50 MM and butterfly valve above 50 MM which is use for chilled water flushing purpose.
And for equipment back flushing we use drain cocks provided in supply line.
what is circuit setter and back flush valve
To allow proper flow of water in HVAC chilled water pipe Circuit setters feature a built-in balancing valve system and measuring points allowing for automatic calibration of the water system.
@@hvacsimplified Then what is the use of PICV if circuit setter is doing the same thing it will add on cost to the project
Please share all hvac calculation excel sheet
Sir ap dono hi condition me bol rahe h ki chilled water bypass jo jayega , plz explain I'm little confused
reyaz Ahmad
Once the room temperature is met, the chilled water flow is bypassed completely for a 3 way Valve, while the flow stops completely in a 2 way Valve
Sir
3way valve Ko open karne se water bypass hoga ya close karne se
reyaz Ahmad depend karta hay k kis position Mai install Kiya hay 3 way valve,
Usually normal condition Mai 3 way valve chilled water supply Kar raha hota hay or by pass off hota hay
Thanks a lot

If 3 way valve will be bypassed after that what happen
There will be no change total as the chilled water system is designed on constant flow pumps. So the water is returned back to recirculate.
What else you what to dictate, feels like childhood history class trying read out the notes for the students.
