Can you please advise which software did you use to make animation for this video? Thanks
Hi… thanks a lot for your feedback. This was done using HTML, CSS & JS. I custom programmed this to have animation.
@@engineeringautomation Really a great job... From your experience what other softwares can be used to make HVAC animations like this... Thanks
You can use powerpoint to create basic to advanced animations.. for professional work, you can used Adobe After effects..
Nice video sir , excellent job you have done , thank you.
But if you can make labels on your lecture in sequence such as
Lect-1
Lect-2
Lect-3
It will be easy for us to follow up
I will try my best... Thanks for your suggestion. Please share and subscribe
EXCELLENT VEDIO, PLEASE MADE ON VFD PUMP AND AHU

Great job brother 👍
Where I can get the complete knowledge of BMS and what is the first step. Can you please guide me step by step?
Hi Khan.. I have uploaded many videos on my channel. Please watch those videos you will get a very good knowledge on BMS. Also, subscribe and share with the friends.
Hii sir, Pls make video more videos on HVAC, FAS. And which software do you use for animation. I Love your videos.❤️❤️❤️
Hi Roshan… thanks a lot for your feedback.. will surely upload more videos.. i have made this animation in Apple keynote similar to powerpoint
Very nice video ! Great work. I have one query regarding the shutdown sequence. How is that achieved during Fire scenario in the Occupant space ?
Hi Pravin, in case of fire, the fire alarm system shall directly shutdown the equipment to prevent fire build up. If shutdown is achieved through BMS, once fire signal is received from fire alarm, BMS will switch off the supply fan, followed by closing of control valve and the associated dampers. Hope this helps. Thank u
@@engineeringautomation Does the exhaust Fan requires to be running (may be for short duration) during Fire scenario ? Or is it the case that all Fans need to be shut down during fire ?
If the fan is designed for smoke extract then the extract fan should work during fire to extract smoke out. Otherwise all the fans needs to be shutdown. Toilet and kitchen fans are not required to be shutdown. Fans which should run during fire for smoke extract must be fire rated with fire rated duct work
@@engineeringautomation thank you so much. Your response and explanation is pretty clear. Keep up the good work.. Appreciated.
Thanks pravin. Please support by sharing our channel to your friends.
Nice Video, Everyone can easily understand the the concept and sequence after watching this video. But your audio i very low. Please increase the audio in upcoming vedios. Thanks.
Hi… thanks a lot for your feedback.. please share and subscribe..
Is this the same SOP for FAHU with heat recovery wheel at its center instead of the Damper?
Hi Sachin, FAHU sequence is different. HRW will work all the time when the AHU starts. The chilled water valve will be controlled based on the supply temperature rather than the return temperature in the FAHU. Hope this helps.
I am really waiting for static pressure control loop video.
Hi prakash… am working on that video only.. will upload soon.. thanks
Please make video of protocol of BMS and other network system
Hi Abdul. Thanks for your feedback. Please see my other videos of BMS systems and communication protocols. I have covered BACnet & Modbus in detail
Where can I get this software to practice and simulate the AHU. I learned a lot today!
Hi yuger.. this was programmed by me in HTML, CSS & JS. There may be simulation softwares. But i am not aware of it for now. Thanks
Thank you and like for the video!
Please explain, why humidity level increases after cooling coil? Shall not it reduced due to condensating on surface of the coil?
Hi John.. thanks for your feedback. The relative humidity level after the cooling coil will be close to 100% as the hot air absorbs moisture from the cooling coil. Condensation happens due to the hot air becomes vapour when comes in contact with the cooling coil. Hope this is clear
@@engineeringautomation i think more water is removed (you need to achieve 100% humidity to remove water from air) as the valve modulates to open. thus humidity will decrease temperature may be too cold, thus need reheating.
Hi yokelee.. yes.. to maintain humidity you need to cool the air more by opening the CHW valve and to maintain the temperature you will open the heater to maintain temperature thus by maintaining both.. hope this helps
@@engineeringautomation You need humidifier to maintain humidity setpoint specially if you are in a very dry and hot weather during summer like here in Saudi Arabia and other ME contries.
Hi Rimando.. i agree. It depends on the nature of the application.
why supply and return air damber not added across serving space ,not necessery? please
not necessary. it depends on the application of use. if there multiple AHU's working in Duty/Standby operation then supply and return dampers will be required to isolate the standby AHU...
Can you explain me How we can set the DPT set value for both series type fan?
Hi Avinash.. i believe you are asking about the DPS for fan run status monitoring. Also i believe only 1 fan will be in operational. In that case, negative probe should go before both the fans and positive probe should go after the 2 fans. Either of the fans running, you can get the status. If the fans are in parallel you need to provide separate DPS for each fan. Hope this helps
What software you are using?
I use multiple softwares
Great Video!
Kindly! Can you tell me what is the Software name that you used the graphical representation ?
Hi Ahmad… thanks a lot for tour feedback.. i have used HTML, CSS and JS for programming, styling and scripting. Then i used keynote to prepare the presentation
@@engineeringautomation great effort!
Good job was very helpful!
Professor, can you send a link to a simulation program for cooling and heating systems for mechanical and electrical parts and control circuits? Thank you.
dear please let me know what software u r using for simulation
Hi.. i used HTML, CS & JS to program and run this simulation
Hai sir what are emergency handle in bms operations like power supply cut how maintain temp
Hi siva.. if the power supply is off for the AHU then temperature can not be maintained… we need power to run the AHU. If u refer when DDC is switched off? In that case DDC will be fed by UPS to avoid power interruption
Which is the best institute to study this full course and what will be the course fee?
Hi Ajith… i dont know any institute teaching this. I can help u with any doubts u have on the BMS system
very useful
Thank you. Please subscribe and share
What are the function of 4 T&RH sensor , please let me know function of 3 other than on return duct considered of space.
without the sensors in the supply duct you will not know if the cooling coil is performing. it helps in measuring the performance for energy saving and better control
Sir which software use in BMS operator
Hi Tousif.. the software is depends on which manufacturer is supplying the BMS system. Siemens uses Desigo, Honeywell uses EBI, Schneider uses EcoStructure etc..
@@engineeringautomation
Sir for these software we should required licence or they are free of cost?
Sir plz make video in Hindi your videos very informative
Hi Shahid.. i dont speak hindi sorry..
DDC panel video
where is the next video for pressure control through VFD
Hi deepika.. been very busy, will upload that video soon. thanks for understanding.
How you implement these logics ?
Hi.. these logics are written in the programming software using ladder logic, functional block diagram, functional chart etc., based on the different manufacturers of the product
please add subtitle, thank you
Hi Nguyen.. thanks for your feedback. Subtitle is there.. you can enable captions in youtube
@@engineeringautomation my youtube can't turn on subtitle :(((
Ahhh… ok. I will try to ad subtitle to the videos..
Seems like it'd be a good instructional video but I cannot understand 90% of what he is saying and the CC doesn't support this video, likely because it can't interpret his accent either...very frustrating as I'm trying to learn as I prepare to challenge the 5th Class Power Eng exam...I will subscribe to this channel in hopes that another person will narrate future videos.
Hi Don, Sorry about that. Will try to sound clear in the upcoming videos. If you need any help, let me know I will do my best.
sir Please make video explained how we can make animation like this.
Hi.. its done in HTML, CSS & Javascript…
Do like to share this video please.
If u dont mind can u possible to give pdf format of ahu sequence of operation
Hi jamal.. I can give you. send email to a.learnautomation@gmail.com
Plc programming???
Hi.. surely will include it in future videos.
What is DP
Hi Shepin, DP is Differential Pressure
Sir please upload basic bms programming details...
Hi mohamed.. will share in future videos..
the temperature and humidity are controlled as individual variables...
I don't think it will be work well.
The right control is controlling Temp and Humidity as a integrated parameters
Hi Christo.. Thanks for your feedback. Yes Temp & humidity are integrated parameters. However, temperature control is more important and humidity is secondary control. Always its priority to have the temperature controlled then humidity. But this depends on application.
How to download these videos
you can use online TH-cam video downloaders
Anna . BMS interview questions cheppandi
HI Rizwan... Watch all my videos you will get a very good knowledge about BMS which you can easily get though interviews..
good vidios but sir please make in also hindi to helping other one please.
Hi Mahendra… thanks a lot for your feedback. .. will try
why the dampers go up to 101% that looks strange
If its out of calibration it will go more than 100%. Anyways it was shown just as a random case. You have a great eye
Please Hindi language me bataye
You should add English captions no offense your accent is very strong and hard to understand
Voice Quilty is not good.
Sir can you make some video in Hindi 😂
Sorry. I am not a native Hindi speaker
