Sir, I’m your big Fan and Student. I’m seeing your every video. Thank you so much sir for sharing your valuable knowledge. Sir you make it one mistake, in secondary pump also fixed with NRV Valve in discharge line, then how to become back pressure will be reached in pump. Reality is when all AHU chilled line is closed, pressure sensor will detect the pressure increase notification and then send the comment to Secondary pump through VFD for stop the pump. Thank You Sir…
Sir Great thanks to you for the explanation.still I have been watching your HVAC related video, and one more need to be explain about the HVAC field scopes, I am a BE mech engg but I was choosed in the HVAC field. I have attended more HVAC foreign client interview ,most of them reject me bcz interviewer told me you are a BE degree over qualification. Now I have 2 years experience in this field currently working in Chennai.
