How Chiller, AHU, RTU work - working principle Air handling unit, rooftop unit hvac system

In this video we learn how Chillers, cooling towers, Air handling units, AHU, Rooftop units, RTU, fan coil units, FCU and duct work work together to form central plant HVAC systems. We cover the basic working principle of how each unit works and is integrated.

I have seen geothermal systems augmenting var HVAC systems, not too often but here and there, aux system used to just help maintain a temp range. I've also seen rain collecting and filtering systems to augment coolers, someone just using available options to invest and s ave $$$ long term. Even saw a set of small wind generators on one rooftop to support the HVAC specifically. Seen a lotta unusual stuff too, but hey construction and environmental systems are a funky field. Enjoying the vids, most of it I know already but you never know where you may learn something new, and although no longer working it's fun to watch and the occasional flashbacks can be amusing, especially residential customers.

Maybe good to add also the possibilities of cross stream heat exchangers, keeping heat in when needed and als create a possibility to use free cooling instead of just the DX to do so.

Just discovered this channel. And like it a lot. I am a Plant Operation Director in the boston mass area. I would love to shoot a video over at my building. And use it to help others and myself how boilers/chillers/re circ pumps etc etc work with eachother. A real life video. Are you interested? I would love to due this at my commercial building. I would learn so much as well.

[@TonyPadgett]

I continue to hear our engineers talk about “package unit”. Is this the same as an RTU?

[@brickcitynetwork]

you can somewhat say that .. difference is a “package unit” can be on the roof or ground, as for the “RTU” it can be a package unit meaning A/C and Heating or it can be a A/C condenser unit of a “split system” on the roof .. hope this help ..

[@CryptoLogicGaming]

Rtu means roof top unit Packaged unit means it’s an all in one does the heat exchange all in one box. Essentially a box that takes and supply’s cold air and exhausts heat elsewhere.

[@alexanderboyd2280]

In a way yes. RTUS are packaged hvac equipment placed on roofs. Package units are placed on the ground but usually can contain similar components

[@viniciusbraga5846]

Yeah, some buildings are even putting Packaged units at strategic floors inside the buildings

[@luismelchor3817]

RTU means RoofTop Unit. Package unit is a unit that heats & cools.

[@EXPLORINGPIPING]

Sir amazing, 12 month ago I subscribed ur channel, only 60 thousand . But now 340000 . awesome

[@BragaLuckas]

I really like the channel. Could you do a video explaining how economizer modes in hvac units help save money on utilities? Thanks

[@EngineeringMindset]

Check our chiller terms essential video, should have covered it there.. I think

[@arsalanchishty8985]

It saves energy by flashing some of the liquid refrigerant coming back from the condenser. The evaporated or flashed refrigerant lowers the temperature of the remaining liquid refrigerant going back into the evaporator and this improves efficiency since you have colder refrigerant in the evaporator to absorb heat. Hope this helped!

[@LinusN1887]

Hi there. I believe you have the piping from the chiller to the pumps switched around like in your other video. Correct me if I'm wrong. I'm an Elec PE for an MEP firm trying to get a basic understanding of HVAC systems.

Hi! Great video! One thing I thought about though was the image seen at 5:38. It shows the air cooler placed before the air heater. Should preferably be reversed!

[@COUPEDUMMY]

Im looking into the sequence of coils atm. Onsite atm all AHU's have preheated coils>prefilter>bagfilter>Chilled water Coil>Heated Coil. So would like to know approved sequence....as all the LTHW preheated coils have rotted from exposure to elements!

[@laff8996]

Any help is appreciated, would an AHU be connected to a RTU to distribute the conditioned air, or would the RTU do all of this itself?

[@mcan-piano4718]

Do you mind if I ask something? Do you have any video about the difference between all-water HVAC system and all-air HVAC system and which units does they use AHU for all air HVAC and also AHU for all-water HVAC but what is the purpose of all-water because it still has ducts for AHU, I didnt exactly understand their difference and benefit over each other. It would be great if you had a video about it. Your channel is great. I hope you will be so successful and I will be glad to support you :)) Thanks for everything.

[@cdcccdcc1286]

As a general fact, water is way better then air in transferring heat. My assumption is that for systems that generate a lot of heat water becomes the better option.

[@ranamubeen5678]

Hy sir plz discuss Taran Rart Ac chelr tarb shot and error message..

[@entertainmentknowledgewith6229]

[@EngineeringMindset]

Yes my accent is British English but it's also mixed with some other places I've lived

[@jimtorres6783]

What you were to run water thru the window frames keeping at a pressure so that it evaporates and send it to condenser inside the building.

[@BenzoNZ]

Thanks so much for this video. Ive come across the typval water cooled chiller in the basement with the cooling tower on the roof on multiple buildings. Can anyone explain why the chiller isnt on the roof too? I must be missing something but it seems like a lot of extra chilled water piping having the chiller in the basement?
