2.5.2 Application limits and operating envelopes
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.
Application envelopes for the various refrigerants can be found in Select software, available at
