in large, low pressure centrifugal chillers. This type of chiller
a very large amount of chilled water for air conditioning purposes
(office buildings, hotels, etc.) at the lowest operating cost
compared to any other type of air conditioning system.
chillers operate in a vacuum on the low side. Air which leaks
into these systems must be purged, and traditionally this meant
that some refrigerant would be lost along with the air. New
purge technology and better maintenance practices have reduced
R-11 losses in these systems.
