Chapter 17.0 Piping Considerations
Care should be exercised when selecting pipe sizes as they will vary according to their application. Chapter 14.0
Sample Refrigeration Circuits provides examples of compressor piping arrangements for the most common
applications.
The motor-cooling line should be channeled from the liquid line; refer to Section 13.1 General Requirements for
more information. Danfoss LLC Applications requires the installation of a sight glass and full-flow liquid dryer in the
motor-cooling line.
NOTE
Some applications may require alternative arrangements. Contact Danfoss LLC Applications for further assistance, if required.
• • • CAUTION • • •
The discharge line must be fitted with a non-return valve to prevent reverse flow into the discharge port, which can cause damage to
compressor components.
All pipe work should be carried out in accordance with industry standards. Brazing without the use of nitrogen will result in debris being
deposited in the pipes, potentially leading to blockage or damage.
Discharge piping should contain a caution label from system manufacturers or compressor installers that the surface is hot.
