Refrigerant Piping Size Chart

Refrigerant Piping Size Chart – Using estimated equivalent feet from step 1, enter chart. The line sizes given on the specification sheets are based on a 5 pound pressure drop for the entire piping run, from 50' to 250'. Refer to dupont refrigerant expert, version 2.0 for actual velocities and pressure drops. Equivalent length is actual length plus friction.

This calculator will compute your suction, discharge, and/or liquid line sizes given the horizontal and vertical line lengths and fitting counts. Problem a simple sizing chart is needed for use by installation and service technicians and system. Line sizes will match up to the. Sizes suction, hot gas discharge and liquid lines;
