Chillers are the
machines that removes heat from a liquid via a vapor-compression or
absorption refrigeration cycle. Most often water is chilled, but this water
may also contain ~20% glycol and corrosion inhibitors; other fluids such as
thin oils can be chilled as well. Chilled water is used to cool and
dehumidify air in mid- to large-size commercial, industrial, and
institutional (CII) facilities. Most chillers are designed for indoor
operation, but a few are weather-resistant.
