Refrigerant Circuit Performance Charts
Use of Charts- Information for the Technician:
The charts are intended for use by trained and qualified air-conditioning and refrigeration technicians only.
The charts are compiled specifically for evaluation and diagnostic purposes, and are NOT designed for use
as charging charts. To apply the chart data to actual conditions: gather the operating pressures, suction tube
superheat & liquid line subcooling values, water temperature change through the heater, and the total unit
amps. Locate a chart that most closely represents current actual conditions. Readings obtained that differ
from the charts in excess of 10% (+ or -), may indicate a problem within the mechanical refrigeration
system. Reference: Troubleshooting Refrigerant Circuit Problems, following the charts. Some interpolation
between charts will be necessary should actual conditions not align reasonably well with the charts. Should
refrigerant circuit readings appear normal, but not the Water DT value, the likely cause will be water flow
above or below 45 GPM. (TropiCal refrigerant circuits will perform acceptably with condenser water flow
between 20 to 70 GPM.)
