2.3.2 Application limits
CAUTION
Inadequate lubrication! Compressor breakdown!
Copeland Scroll
compressors are qualified for operation inside the envelope published by
Emerson Climate Technologies. The envelope is defined according to
Emerson Climate Technologies testing and experience. Operating a
compressor outside the envelope might lead to compressor failure which
would be the heat pump manufacturer’s responsibility. 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. In
the same way, the superheat at the compressor suction must always stay
below a maximum limit specified by Emerson Climate Technologies,
depending on the model and for which the operating envelope is defined.
NOTE: The application envelopes shown below are for R410A.
ZH04K1P, ZH05K1P (up to S/N 15F)
ZH04K1P, ZH05K1P (from S/N 15G onwards)
ZH06K1P to ZH19K1P (all S/N)
