Automatic Glycol make-up system for close loop system
(OP)
I am looking for piping connection/diagram describing operation of automatic glycol make-up for close loop glycol/chilled water system. Specially I would like to know how the initial fill up of the system occurs.
Thank you.
Thank you.

It is also available in ASHRAE Systems volume.
Glycol mix just takes the place of domestic water fill with a pump adding the pressure to fill the system. Pump will shut off when pressure stat reaches set-point.
Pressure is about 6 psig/floor (12' floor-to-floor) of building plus 5 psig extra for venting.
