Determination of initial frequency for heating
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 × (-5/128 × (DOA - 15°C) × FINI1+FINI1)
3/ 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
