Hi Ameen… thanks a lot for your feedback.. please share our videos and subscribe to our channel.. 👍

@@engineeringautomation waiting for your next video..

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..

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.

Hi Sayyad.. Thanks a lot for your feedback and supporting our channel. It means a lot....

One of the best KZfaq channel on building automation system. We are always greatful for your effort for sharing your knowledge with us.

Thanks a lot.. appreciate it..👍

Hi Shamsher, thanks for the feedback. Will do vfd on pumps and vfd in future

Hi Manoj, definitely will upload more videos. Please subscribe and support

Hi Abdul. Thanks for your feedback. Please see my other videos of BMS systems and communication protocols. I have covered BACnet & Modbus in detail

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.

Hi Roshan… thanks a lot for your feedback.. will surely upload more videos.. i have made this animation in Apple keynote similar to powerpoint

Hi prakash… am working on that video only.. will upload soon.. thanks

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

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.

Hi… thanks a lot for your feedback.. please share and subscribe..

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.

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

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...

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!

I use multiple softwares

Hi deepika.. been very busy, will upload that video soon. thanks for understanding.

Thank you. Please subscribe and share

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

Hi.. i used HTML, CS & JS to program and run this simulation

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

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

Hi Ajith… i dont know any institute teaching this. I can help u with any doubts u have on the BMS system

Hi Shahid.. i dont speak hindi sorry..

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?

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..

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.

Hi.. its done in HTML, CSS & Javascript…

Hi jamal.. I can give you. send email to a.learnautomation@gmail.com

Hi.. surely will include it in future videos.

Hi mohamed.. will share in future videos..

Hi Shepin, DP is Differential Pressure

you can use online KZfaq video downloaders

HI Rizwan... Watch all my videos you will get a very good knowledge about BMS which you can easily get though interviews..

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.

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

Hi Mahendra… thanks a lot for your feedback. .. will try

Sorry. I am not a native Hindi speaker

the other are much worse
