Determination of initial frequency for cooling

Initial frequency FSR is determined based on the correction of outside air temperature (DOA)

and discharge pipe temperature (DO) in accordance with the above matrix.

FSR = KFIDO ° (2/128 ° (DOA - 35˚C) ° FINI1+FINI1)

KFIDO varies depending on discharge pipe temperature DO

When DO ≥ DOFINI (45˚C): KFIDO = KFIDOH (128/128) --- Hot start

When DO < DOFINI (45˚C): KFIDO = KFIDOL (179/128) --- Cold start
