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 ?

Hi sir, what is the test pressure “for connecting copper piping “of Dx AHUs ?
Thank you sir for such kind of valuable videos❤
good class.. thank you.
Great sir
Your class was very useful please upload so give many contents thanks you cheta
Good explanation
Hai eng. Pls explain ‘ Heat exchange for building why not using directly distric cooling system at building
Thank so much sir
Thanks for your support
Good ❤❤❤
insulation for nitral rubber insulation-25 mm thick at CHW system
Really helpful, appreciated your efforts 😊
Nice
Good sir❤
Sleeves or Arma flex insulation chilled water pipe
Sir 1 video in malayalam 😊
How do you calculate air flow designs?
👍
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
Nitrile rubber
ചേട്ടാ മലയാളത്തിൽ ഒന്ന് പറയാമോ
Sir 1video hindi me bnaiye
manasavanilya
Insulation name amoflex
Sir you have good knowledge about HVAC but your answers are not satisfactory
Please elaborate in simple details.
Nitrile Rubber
So DIFFICULT FOR U TO SAY COMPLETE ASHRAE HAVE TO LOOK MOBILE FOR FULL FORM. ?? 😂
