Hello anyone can advise me how much chill water supply pressure I needed?


I am going to install the Heating & Cooling Unit (H&C) for mixing process. The H&C unit stated the requirement for the chill water supply are as below:


The H&C unit data:

max. chill water pressure : 6 bars

min. chill water differential pressure : 1 bar

Consumption chill water supply at 15 degreeC, flow at 0 degreeC = * 865l/h


** Output data valid for room temperature 20 degreeC, chill water inlet 15 degreeC & 3 bar differential pressure between cooling chill water inlet and outlet.

Currently, our chill water supply at 3.5 bars & return at 3 bar.


Does the H&C data sufficient?
