Difference between a large condesing unit and a chiller, and between VRF and VRV

[tony_the _tiger]

Hi all,

New to the industry, hopefully off to do my Level 2 at college shortly.
Was just wondering what the difference between a large condensing unit and a chiller of the same size is?

Also what is the difference between VRF and VRV?

Many Thanks.

Rich.

VRV = Registered name for Daikin
VRF = Every other manufacturer

A large condensing unit condenses refrigerant for use elsewhere, remote evaporator(s).
A chiller cools water/brine for use in remote cooling equipment.

Evening Brian,

you beat me to it whilst collecting pics :)

Evening Tony,

At a guess is it frosties for breakfast ;)

as Brian described above, with a couple of pics to help understand mate

condensing unit consists of main components 'compressor & condensor'
7262
water chiller consists of everything needed to cool the water system in use
7263
VRV is a condensing unit of sort but is connected to multiple evaporators
7264
VAV is an air make up system
7265

pictures might help as we could be here a very very long time trying to explain them all

welcome to Re by the way & the industry

He doesn't know Chillerman what he started, he better had think twice before joining this industry. :-)
Hey welcome Tiger. Is Tiger your last name?

Hi Peter

'tony the tiger' unless my poor memory fails me was the cuddly tiger on the 'Kellogs Frosties' advert....thats why I hazard a guess in my previous post that he has 'frosties' for breakfast :)

The things that stay with you for life, I still have 'chocolate ready brek' which is a bit like porridge with a chocolate flavour :D

As for what he's started mate, this could be the biggest thread ever, if we dive in & try to explain how all the systems he has asked about, work/differences/set-up/faults

Seriously as Peter said this is not an industry to just think I will have a go at that, it's a never ending learning curve & thats once you truly get your head around the basics, but I do beleive 'nearly' anyone can do anything you just got to try .... note the nearly, its not a trade for everyone mate,

Useful piccy's CM but he didn't ask about VAV, it was VRV and VRF. :)
