Borders mark typical operating ranges that can be ex pect ed
for suction and discharge pressures under mod er ate to full
load, 44°F setpoint, with ambient air tem per a tures between
90-100°F. This is only a guide line and readings beyond these
ranges will occur.
Vapor entering compressor should be superheated 12-15°F.
Liq uid from condenser should be subcooled 12-15°F.
This chart shows characteristics of Refrigerant R-22 (Monochlorodi
ß
uoromethane) when in the ‘sat u rat ed’ state.
