Welcome back eng and automation. 🥰

[@sj-pr2xs]

Very informative video. All doubt s cleared sir salute❤❤❤

[@yungerallenelectricalcontr6415]

I loved this video ! I shared with my team too.

[@engineeringautomation]

Hi.. thanks a lot for your feedback. Please subscribe to the channel

[@shamsheralam8862]

thanks a lot, very clear as always....please make more vedioes on PDT, PDS, FT, TE, thanks

[@engineeringautomation]

Hi Shamsher.. thanks a lot for your feedback. Surely will do

[@KlausIsLivee]

Took too long sir, but happy to have you back ☺️

[@engineeringautomation]

Hi Usman.. thanks a lot for your support

[@KlausIsLivee]

@@engineeringautomation sir can you help with heat load Calculations and include some good examples as always 😌

[@engineeringautomation]

Hi usman.. i will try in my future videos..

[@KlausIsLivee]

@@engineeringautomation Thanks alot Sir 👍!!

[@user-uu4ob3mb3y]

brother please share using which software you are creating your vedioes please, your vedioes are really very interactive and very clear

[@engineeringautomation]

Hi tausif.. i use keynote for the presentation

[@katturprakash]

during winter season while room temp below the setpoint.. how will pressure independent VAV (w/o heater) works... how warm air from Ahu pass through VAV...

[@engineeringautomation]

Hi.. during winter if the AHU is provided with reheat coil, the warm air will be supplied to the VAV’s. Since the pressure independent VAV’s do not close fully and minimum airflow is being supplied to the space always, the room temperature will be maintained. The AHU will supply the temperature at a constant rate…

[@MR-backup]

Sometimes, when VAV's do not have Electric Heat coil installed w/ unit, the occupancy space may have been designed with heat from occupants and miscellaneous electronic loads, e.g. lighting, computers, refrigerators, etc.

Hello Engineering & Automation your videos are really great! How do you make the videos ?

[@engineeringautomation]

Hi faiz.. thanks a lot for your feedback.. am glad u like it

[@faizahmedshaheen6919]

@@engineeringautomation how do you get this idea to make videos and on which platform?

[@faizahmedshaheen6919]

@@engineeringautomation it’s really interesting

[@engineeringautomation]

Hi Faiz.. all these videos are from my personal experience and references from technical Documents.. hope this helps u to learn something useful

[@adarshkollappillil720]

Please do a video of bms sequence of a water cooled chiller

[@engineeringautomation]

Hi adarsh.. sure will do.. kindly subscribe.

[@kompshi]

i like your videos so much but can you please talk in a loud and clear voice. it is hard sometimes to understand. but the videos and the information is absolutely wonderful. thanks for your videos.

[@aejazaslam3021]

yes even he is too fast .. had to see sub titles to clearly understands his words .

[@engineeringautomation]

You can slow down the video..

[@engineeringautomation]

Hi.. you can slow down the video speed..

[@derrickdcruz5212]

Hi Sir , i wish to know about Fresh Air Fan system. Can this system work without CO2 Sensors?

[@engineeringautomation]

Hi derrick… it depends on the system you use.. normally fresh air is used to bring down the CO2 level.. so using fresh air fan does not require to monitor CO2 levels

[@justmiddlefingers811]

Mechanical engineer BMS suitable?

[@engineeringautomation]

yes... BMS controls all the mechanical equipments.

[@mohammedforhadakhter2174]

Need integrated software of BMS including Finance, Accounts, and Inventory for a small property developer.

[@engineeringautomation]

Hi Akhter.. u can not have an integrated software with finance and accounts.. there are CMMS softwares which does that.. but u need to integrate to CMMS to BMS to enable inventory, procurement, invoicing etc., hope this helps

[@masud-ahmed-cuet]

This is just theory; how would you implement it ?

[@engineeringautomation]

Hi.. yes it explains the basic concept and working principle. To implement you need yo have hands on experience with controllers and BMS devices
