General requirements
Proper piping practices should be employed to:
Ensure adequate oil return, even under minimum load conditions (refrigerant speed, piping slopes…). For
validation tests see section Manage oil in the circuit.
Avoid condensed liquid refrigerant from draining back to the compressor when stopped (discharge piping
upper loop). For validation tests see section Manage o cycle migration.
Piping should be designed with adequate three-dimensional exibility to avoid excess vibration. It should not be
in contact with the surrounding structure, unless a proper tubing mount has been installed. For more
information on noise and vibration, see section Sound and vibration data.
