Hey can you guide me ive interview at mumbai airport for mechanical engineer so many people tell me to prepare HVAC so can you tell me what are the questions as per fresher? Please
i am from India Kerala . I finished Mechanical Engineering (Btech) and Woked As Hvac - project engineer- design Section for 1 year in Kerala ( mostly was Using Autocad,Hap,Duct sizer, Pipe sizer) After that Joined an HVAC course And BIM course ( 5 month Course) And learned Revit and Navis work and Few more basics Of HVAC . I am coming to UAE ( Sharjah , my parents are There ) i want a job in This Field ( HVAC design) . What all should i do ?

Thank you brother ❤❤
Sir, I'm very happy to see you. I have worked as an HVAC Ducting Supervisor in ETA Doha for more than 12 years. Thank you very much.
Any vacancy
Where are you now? @@johnlinsonkunjumon06

good class.. thank you.
Your class was very useful please upload so give many contents thanks you cheta
Thank so much sir
Really helpful, appreciated your efforts 😊
Great sir
Good explanation
Good ❤❤❤
Hai eng. Pls explain ‘ Heat exchange for building why not using directly distric cooling system at building
Good sir❤
Thanks for your support
Wish! I could work under you..
Nice
insulation for nitral rubber insulation-25 mm thick at CHW system
Sleeves or Arma flex insulation chilled water pipe
Sir 1 video in malayalam 😊
How do you calculate air flow designs?
Nitrile rubber
You have good knowledge, but the way of teaching isn't good enough, and also not a simple. , dear Sir, please explain in simple way
👍
Sir 1video hindi me bnaiye
ചേട്ടാ മലയാളത്തിൽ ഒന്ന് പറയാമോ
Insulation name amoflex
manasavanilya
Sir you have good knowledge about HVAC but your answers are not satisfactory
Please elaborate in simple details.
So DIFFICULT FOR U TO SAY COMPLETE ASHRAE HAVE TO LOOK MOBILE FOR FULL FORM. ?? 😂
Rotttunnnddaaaa🤣
