2.1 Common information about Copeland Scroll Digital™ compressors
The Scroll compressor has been under development at Emerson Climate Technologies since
1979. It is the most efficient and durable compressor Emerson Climate Technologies has ever
developed for air conditioning and refrigeration.
These application guidelines deal with Copeland Scroll Digital™ compressors for
refrigeration from ZBD21K* to ZBD114K*, ZFD13K* to ZFD41K*. These compressors
include a wide range of capacities, electrical options and features.
Table 1: Cooling capacity for medium temperature compressors @EN 12900 Medium temp.
Table 2: Coefficient of performance (COP) for medium temperature compressors @EN 12900 Medium temp.
Table 3: Cooling capacity in kW and COP for low temperature compressors @EN 12900 Low temp
EN 12900 MT: Evaporating: -10°C, Condensing: 45°C, Suction gas: 20°C, Sub-cooling: 0K
Except for R513A*, Suction Superheat = 10K
EN 12900 LT: Evaporating: -10°C, Condensing: 45°C, Suction gas: 20°C, Sub-cooling: 0K
Copeland Scroll Digital compressors have one Scroll compression set driven by a single or
three-phase induction motor. The Scroll set is mounted at the upper end of the rotor shaft of the
motor. The rotor shaft axis is in the vertical plane.
