Operating Pressures
There are many variables (airflow, air temperatures) in an air conditioning system that will affect operating refrigerant
pressures and temperatures. The charts below shows approximate conditions and is based on air flow at the rated
SCFM, entering air at 80.6 °F(DB), 66.2 °F(WB) in cooling, 68 °F(DB) 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.
