2.3.2 Application limits
CAUTION
Inadequate lubrication! Compressor breakdown! Copeland scroll
compressors are qualified for operation inside the envelope published by
Emerson. The envelope is def ined according to Emerson testing and
experience. Operating a compressor outside the envelope might lead to
compressor f ailure which would be the heat pump manuf acturer's
responsibility. The superheat at the compressor suction inlet must always be
suf ficient 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. In the same way, the superheat at the compress or
suction must always stay below a maximum limit specif ied by Emerson,
depending on the model and for which the operating envelope is defined.
NOTE: The application envelopes shown below are for R410A.
