Thanks for your useful video Sir. I understand the working principle of expansion tank very clearly. Thanks a lot. Please upload useful videos like this.
Thank you so much for your breaf explanation bro. This was an interview question when I attend interview for MEP supervisor in dubai on 30/01/2021. But I was not answer properly. Even though I was selected and I am waiting for offer letter. Interview Questions are 1) What is the use of capacitor in compresser in refrigiration system 2) Make of chiller, How many circuits in chiller, compreser type, how many condenser fans are used in chiller having 2 circuits. 3) Use of Expansion vessel and its function 4) what is use of differential pressure switch in AHU or FAHUs 5) What are main componants in refrigiration system and its operations Electrical related Questions are 1) Use of capacitor in MDB 2) What are the types of electrical meters we are using to measure electrical parameters 3) Draw DOL starter and comparisson of star delta and DOL starter 4) How to measure capacitor value in capacitor bank 5) what is maximum demand you had in previous site 6) Function of ATS panel 7) What is power factor and what will happend in power system if we are not maintaining power factor
Anna.. my name moorthi..please explain about sugre vessel function.. here mostly water treatment plant available sugre vessel.. but that function 100% I don't know.. can you update video about that??
Set point will depend on the system pressure you have on the chilled or hot water loop. Calculate the pump head and then you can approximately know your system pressure.
@@lohisya_media your video is telling about expansion tank where the heated is required . But chiller side , more heat is collected from AHU or FCU then temperature and pressure is increased while reaching to chiller . How can maintain the pr. and temp. Before primary pump ? My guessing is expansion tank is feeding the water to constant flow side to maintain the pressure and temperature also.after that filling the water in expansion tank through make up line . Is guessing correct ?
You need to calculate the total system volume first. This includes volume on the pipe and the volume on your equipments running within the closed loop. Then know the return and flow temp of your system, for example for chilled water it is usually 6 and 14 C. Calculate the density at both these temperatures. Finally expansion tank volume (L) will be (Density of water at 14C - Desnity of water at 6C)kg/m3 x system volume (m3)
After long time I understand the working of expansion tank. Good
Sir, intha video paathuthan subscribe pannan unga channel... Clear ah solirukeenga... Niraiya video pathan intha video am so impressed....
Thelivana vilankam nandri bro.
Thanks for your useful video Sir. I understand the working principle of expansion tank very clearly. Thanks a lot. Please upload useful videos like this.
Well explained sir... thankyou
Very nice thala. Good example.
Thank you sir nice video
Thank you so much for your breaf explanation bro. This was an interview question when I attend interview for MEP supervisor in dubai on 30/01/2021. But I was not answer properly. Even though I was selected and I am waiting for offer letter.
Interview Questions are
1) What is the use of capacitor in compresser in refrigiration system
2) Make of chiller, How many circuits in chiller, compreser type, how many condenser fans are used in chiller having 2 circuits.
3) Use of Expansion vessel and its function
4) what is use of differential pressure switch in AHU or FAHUs
5) What are main componants in refrigiration system and its operations
Electrical related Questions are
1) Use of capacitor in MDB
2) What are the types of electrical meters we are using to measure electrical parameters
3) Draw DOL starter and comparisson of star delta and DOL starter
4) How to measure capacitor value in capacitor bank
5) what is maximum demand you had in previous site
6) Function of ATS panel
7) What is power factor and what will happend in power system if we are not maintaining power factor
dear brother, these are the only questions or beside these there were more questions also?
sir foam suppression system how to working and how to install in foam bladder tank video podunga sir
very informative video 👍🏼👍🏼👍🏼
Bro pressurized coil hot water generator pathi video podungaa
sup sir very usefull sir thanks I waiting for economize detail s
Thank you for your explanation bro... But please explain which locations it is placed
Example chiller outlet or pipeline end point
Can you make video about the Hvac Pressurization unit and the working principle, and what is the set point to be maintained always
Ok will do it
is this same as buffer tank ?
Anna.. my name moorthi..please explain about sugre vessel function.. here mostly water treatment plant available sugre vessel.. but that function 100% I don't know.. can you update video about that??
Sir one doubt system pressure means? Design pressure of the entire chilled water system or the tank ?
❤❤🎉🎉🎉❤❤
From sri lanka
Please explain about CRAC AND CRAH Units
This very useful thala
Pot strainer pathi video podunga
Where its using in hvac return line?
I have one doubt
I don't understand about Section pressure ,and please explain one more.
Bro
Explain economiser work HVAC
Sir pre cooling tank connected with expansion tank what is the purpose of pre cooling tank
Very usefull
Good
What is the difference between expansion tank and pressure tank?
How many type material using in expention tank
Tq anna
Water cooler all types explain today
Thanks bro
Nice❤
Hi
pls share the calculation for pressurization unit
Hello sir,
1)How can we determine the setpoint of an expansion tank?
2) what is the difference b/w expnsn tnk & przristn units?
Set point will depend on the system pressure you have on the chilled or hot water loop. Calculate the pump head and then you can approximately know your system pressure.
Hello sir expansion value all types working animation explain
Please explain this topic in telugu sir... Please
How to understand this topic
Please tell me about chiller . Not a heater ..
Thanks ..
Bro can't understand
Please be clear
@@lohisya_media your video is telling about expansion tank where the heated is required .

My guessing is expansion tank is feeding the water to constant flow side to maintain the pressure and temperature also.after that filling the water in expansion tank through make up line .

hi ji. How to to size the expansion tank.
You need to calculate the total system volume first. This includes volume on the pipe and the volume on your equipments running within the closed loop. Then know the return and flow temp of your system, for example for chilled water it is usually 6 and 14 C. Calculate the density at both these temperatures. Finally expansion tank volume (L)
will be (Density of water at 14C - Desnity of water at 6C)kg/m3 x system volume (m3)
What is anti freezing temp
How to find expansion tank not functioning please answer me.
Water hammering,
Pressure drops in pipe line ,
Or more pressure in pipe lines,
Sub cold,super heat enna sir
Very nice sir
Can you plz explain in Telugu
i am sorry but the 2 language crossing i cant understand nothing he says
Please tell in hindi Or English, please
Thanks ji I will try to make video in English
Sir please make this video in english version.
