to compressor, system designer can use an accumulator and install it before the suction port or simply maintain
good suction superheat to avoid liquid refrigerant compression.
e. Parallel system
In the rack or parallel system, oil management is extremely important. Due to open type compressor needs an
external oil separator, sharing of a common oil separator becomes possible. Using parallel system can have the
following advantages.

Extend the capacity limitation to higher level with multiple compressors.

The combination of compressors can be decided by actual needs. There is no need to use the identical one.

Each working compressor can have its own working temperature by system design and arrangement.

Maximize the usage of external oil separator.

The start-up current can be lower at parallel system compare with the system with one bigger compressor.

Extensive options of capacity control which helps compressors work safely.
The concept diagrams of twin compressor parallel system are shown below. They have slightly differences
according to their operating condition and accessory application. Accessories installed on the system diagram are
recommended for the safe operation and system protection. If other application and protection are considered to
be installed, please contact HANBELL or local distributor/agent for more information or further confirmation.
