Table OP-1: Operating Pressures
GENERAL: There are many variables (airflow, air temperatures) in an air conditioning system that will affect operating re-
frigerant pressures and temperatures. The chart below shows approximate conditions and is based on air flow at the rated
SCFM, entering air at 80.6 °FDB, 66.2 °FWB in cooling, 68 °FDB in heating. (+)Heating data with 35 °F EWT is based on the
use of an anti-freeze solution having a freezing point 20 °F lower than the minimum expected entering temperature.
