Bhai jb wet bulb mai evaporation kam hoga, wo tb jb atmoshphere mai humidity zyadat hogi to us condition mai wet bulb tem to kam hoga na, zyada kse btaya aapne, wet bulb to evaporation zyada hota hai tb zyada hoga na
Evaporation will be more when RH is less...this condition arises when wet bulb temperature will be less ...
Range nahi,jitna approach Kum hoga utna efficiency jyada hogi
@@mohamed-ip7dymy mistake .. thanks for correction
°F = °Cx1.8+32 I am correct or not
Correct
Very nice
Sir, nice video. Understood thumb rule. Can you please make video on actual load calculations also.
@@GaneshKamble-gd9cg sure , I will try if I get time ....it's is very time spending job .... making video on you tube .
@@kamaal6918 Thanks for reply Sir. I absolutely understand you. You are doing a great job. Is it possible for you to send me some server room example calculations. I will study on that. Please. Thanks you.
Is it possible to get in touch with you Sir. Since we are in HVAC.
Thank you nice video. Can you please make video for battery room also.
PuE ? Full forms

Nice❤❤
Simple and straight explanation ... All in one video to understand chiller performance ... 👌👌👌
Thanks
thanks for given information
Very good
It was a good video but at the a wrong statement was given that smaller the Range better the efficiency. But he actually meant was Approach but somehow Range got spoken. The correct statement is: *Smaller the Approach, better the Efficiency.*
Thanks for your feedback ..this will help us to improve a lot.
262tr ka 920kw hota h sir
Yes 262 ka 920 thermal kw not electrical kw hota h
Which called kwr
Rong
What wrong sir
If you talking about conversion from tr to kw thermal then the 1TR =3.517 KW
If you are talking about the electrical consumption of the 1 TR AC , then it depends on the what type of AC you are using
i have a 20 42 u rack per rack 15 kva we are considering area is 2000 sqft so i required 90 ton od PAC is it rt
90 TR +standby units also
Well done,...... but from where did u find out these values, like GPM=700, m= 700 Cp= 227.12. Also explain about these values
Thank you for your information 🙏
Very informative video How to find multiply factor 10???
Some of the anemometers doesn't require a multiplier factor ,which is require it it mentioned at the display
Hi can you please share a procedure, How to Calculate CFM for PACs / PAHUs
You can take CFM on the suction side on the filter, or on the suction grill
Also you also can check the CFM on all supply air perforated tile .
PACs / PAHUs are bottom through, above that there will be a false floor on it.
Bhai ye to bataoo wet bulb temperature wala line ja kis se raha hai cooling tower mai condenser se ya evaparetor se
Wet bulb temperature of air .. entering the cooling tower
Cooling tower m Jo air enter kar rahe h uska wet bulb temperature
That means approach can not be zero(0)
Nice video, except that you just switch to Hindi in the middle of the video. I would suggest just stick to one language. But thanks for the infomation.
Thanks for suggestions..we will keep improving ☺️
yes should be english only for easy understanding
Chiller machine ki in & out let per install pressure gauge se chiller machine ke gpm ko find out kar sakte hai kaise? Explain
No , we cannot calculate the GPM by pressure
Kisi site per 200 Ton water cooled chiller machine 3 ph scrow compressor hai uska hp aur kw kitna hai kaise find out karenge eska calculation kaise hoga explain.
To calculate the power consumption you need to put in a power analysis, if you don't have such the calculate the ampere by clamps meter the put the formula kw = 1.73*415*I(Amps)*power factor (.85)/1000
I will come approximately 180 kw if it air cooled chiller , or if it water cooled then will 130 kw at full load
Where do take electrical consumption use? From main breaker of a chiller? Please let me know
Fabulous explanation ❤
Thanks
Why are you making difficult for all tell them direct take the reading in CFM no need to multiply
Dear sir ji Agar koi windows nhi ho to
Then do not add windows heat load in calculator, wall head load will be considered in the area , This is a approximate method of cooling load calculation, not actual . So the result may differ slightly,
Ok sir ji. Thank you sir ji...
Good.
Video upload pannuga
Could you pls explain it , i m not understand
सर मेरा एक सवाल है गैस की ऐसी क्या प्रॉपर्टीज है जो पानी के टेंपरेचर को 6-7© सेल्सियस कर देती है।
Refrigerant ki low boiling point ak aise property h jiski wajah se vo phase change karta h aur heat ko absorb kar leti h , for example R22 ka boing point at -48 dree at atmosphere pressure,so as we increase the pressure boiling points increase so at 60 psi the point point is about 4 dreee so it get cooled at 60 psi , jabki water ka boing point 100 dc h
Low boiling point ak aise property h jiski wajah se refrigerant heat absorb karke phase change karleta h , for example R22 boiling point at atmospheric pressure is -40dc so if you keep R22 at atmosphere pressure it's tem will be -40 dc, so jab R22 ka pressure 60 psi hota h to vo 1.1 dc temperature hota h and jab vo Pani k contact m ata h to Pani 6 to 7 dc tak thanda ho jata h
Very very well explained.... Thank you so much 🙏
Average velocity ko 10 me kyu multiply kiyea he
Some of the anemometer need multiplying factor 10 . Pls ensure your anemometer has MF or not .
Thank you soo much It was soo easy 🙏🙏
Chiller gas use which temp limit
Pls elaborate what you want to ask , sorry i don't understand yr question

Very nice, sir bhut achchhe se aap ne bataya hai.

Bro nice video but ineed to know that I'm done ITI in R and AC 2 years course at 2002 still I'm working as HVAC and Chiller plant operator now but i need to know that how developed by carrier in my life salary is less i required job level also high and also salary high so what is your suggestion please give me best
A salaried person growth can happen only by continuous learning and enhancing the qualifications, you have done your ITI in 2002 since then you have not done any course, that is the reason for less growth or no growth. Now you can start a side business in refrigeration and air conditioning repairing and installation , contact to minimum 10 dealers ask them that I m looking for a job . If you get a chance to have a job with contacting the company there you will get a good exposure with the customer and later you can build your own company . Second you can search for a job in the gulf and you get good package ....i have so many contacts in the gulf if you are interested pls let me know .
How you making out now in the field?
Excellent

Nice video 😊
10 se kyo multiple kiya
Some of the anemometer have multiplying factor of 10 while calculating the fpm reading and factor is mentioned in the meter only . First check if yr meter is old one and it is having mf, Otherwise if the meter is giving reading in direct fpm then no need to multiply by 10 .
Please make vdo on VAM ( Steam capacity calculation ) & Screw Compressor as well
Thank you for your valuable feedback , sure we will make the video on VAM
