Hi bro ..I have a one dough...we are using air cooled chiller in our factory.. already we are supplying the cooled air inside the factory by AHUs..but same time HVLS HIGH VOLUME ceiling fans also running..is affect the cooling efficiency inside factory?
Nice bro...keep doing informative videos
Bro nalla panringa.hvac software related Q&A interview pathi solunga
Excellent explanation
Very useful brother
Thanks sir

Hi bro ..I have a one dough...we are using air cooled chiller in our factory.. already we are supplying the cooled air inside the factory by AHUs..but same time HVLS HIGH VOLUME ceiling fans also running..is affect the cooling efficiency inside factory?
No bro it will not effect the cooling system HVLS fans rotate with 2 to 3 mph which will give effective air cooling it will combined with HVAC
