Hey guys, just a quick question on a headmaster valve please:
I understand that they are used for low ambient head pressure control ..... but today I came across them in a Uniflair upflow close-control cabinet (Italian make), used in comms/computer server rooms. 2 fridge circuits (R407c) in the cabinet and water-cooled condensers. The headmaster valve is within the cabinets in the room.
I am sure I am missing something here; why would I want to control head pressure based on inside room temperature?
Thanks
