2.4.3 Application limits
CAUTION
Inadequate lubrication! Compressor breakdown! The superheat at the
compressor suction inlet must always be sufficient to ensure that no refrigerant
droplets enter the compressor. For a typical evaporator-expansion valve
configuration a minimum stable superheat of at least 5K is required.
The application envelopes for the refrigeration Scroll compressors with various refrigerants can
be found in Copeland brand products Select software available at www.climate.emerson.com/en-
