Abstract:
Since its initial recognition in 1928 and
commercialization in 1936, R-22 has been applied in
systems ranging from the smallest window air
conditioners to the largest chillers and heat pumps,
including those for district cooling and heating.
Individual equipment using this versatile refrigerant
ranges from 2 kW to 33 MW (0.5 to 9,500 tons) in cooling
capacity. R-22 use includes equipment with
rotary-rolling-piston, reciprocating-piston, scroll,
screw, and centrifugal compressors and experimentally,
absorption cycles. No other refrigerant has achieved
such a wide range of commercial capacities or
applications.
