Hi, I'm basically new to this although i have the background in AC piping installation for i am in the field of construction.

I just wanted to ask this.

Is it normal to have the condenser outlet/inlet stub-out sizes smaller than that of the evaporator in a centrifugal chiller or for any chillers for that matter?

its just that i think its odd (or my logic is bad) that the cooling water which goes through the Condenser will be smaller in volume compared to that of the chilled water that serves the FCU's passing through the Evaporator.
I mean, will heat transfer be enough between this two (via the refrigerant) to "cool" the chilled water supply or the condenser return (outlet supply to the CT) water be heated near its boiling point so to serve the cooling required for the CHW? (just mumbling here)

My unit in question is a YORK 76.6 RT with the condenser pipe size inlet/outlet at 4" dia. and the evaporator stub-outs at 6"dia.

I did not include the technical data since I'm just asking out of curiosity with this.
