Introduction
Water chillers using the vapor-compression refrigeration cycle vary by the type
of compressor used. The compressor works to draw in refrigerant vapor and
increase its pressure and temperature to create the cooling effect.
Reciprocating, scroll, helical-rotary (or screw), or centrifugal compressors are
generally used in water chillers that employ the vapor-compression
refrigeration cycle.
Absorption water chillers make use of the absorption refrigeration cycle and do
not use a mechanical compressor. The absorption refrigeration cycle is used in
both small and large air-conditioning equipment. This clinic, however, focuses
on large water-chiller applications of the absorption cycle. The different types of
absorption water chillers will be discussed in detail in Period Two.
