The normal outlet air temperature and pressure of the refrigeration
cycle depends on various conditions, the standard values for them
are shown in the table on the right.
Normal Pressure and Outlet Air Temperature (Standard)
Gas pressure
MPa (kg/cm

G)
Outlet air
temperature (°C)
Cooling Mode
0.9 ~ 1.2 (9 ~ 12)
12 ~ 16
Heating Mode 2.3 ~ 2.9 (23 ~ 29)
