BMS Sequence of Operation - Air Handling Unit with Startup,Shutdown sequence & control loops
Ғылым және технология
AHU plays an important role in the building air conditioning system where its complete operation is automated with BMS. There are various control loops for an AHU where BMS provides precision controls to maintain temperature, humidity, CO2 levels in a building.

Is this the same SOP for FAHU with heat recovery wheel at its center instead of the Damper?
@engineeringautomation

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.

Can you explain me How we can set the DPT set value for both series type fan?
@engineeringautomation
2 жыл бұрын
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

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?
@engineeringautomation
2 жыл бұрын
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

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

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
