Air cooled chillers have come a long way in efficiency and life cycle longevity. With efficiency’s
above 20+ IPLV the gap between using water cooled and air cooled has changed. Items such as
VFD driven condenser fans; integral free cooling; and optimized compressor designs make these
air cooled machines extremely efficient and longer lasting. This presentation will cover the
advancements in air cooled chillers that are changing the landscape and design practices for
chilled water systems across our market.
