1.3. General operation

• These split units are used for comfort cooling and are equipped with an inverter.
• The rotation speed rps (= rotation per second) of the inverter driven compressor, modulated by the inverter, can be varied
according the required capacity in the room.
• The compressor capacity step is changed in order to reach target compression ratio. The target compression ratio is calculated
from deviation between actual and target condensation and evaporation temperature.
• Tc (condensing temperature) is used in heating mode.
• Te (evaporation temperature) is used if any indoor unit operates in cooling mode.
• The evaporating temperature in the heat exchanger is controlled by the electronic expansion valve.
• When indoor unit is selecting heating mode, discharge gas is supplied by the outdoor unit to the indoor unit.
• When indoor unit is selecting cooling mode, liquid refrigerant is supplied by the outdoor unit to the indoor unit.
