Operating Envelopes
NOTE
The maximum Saturated Discharge Temperature (SDT) of the operating envelope represents the limit for compressors with
maximum FLA settings.
The SDT for a compressor with a lower maximum current rating is lower than that shown and is related to the FLA rating of
the particular compressor. The lower limit is related to minimum pressure ratios required to eect proper motor and power
electronics cooling with standard refrigerant circuit components.
(1)
The actual obtainable capacity will be dependent on specic operating characteristics of each compressor model.
Refer to the current authorized compressor selection/rating software for more exact values and conditions.
