Indoor Air Temperature Control ", but also the frequency of the compressor's inverter is controlled in accordance with T and fluctuations in indoor air temperature.
  • Page 90 4) Condensation Temperature Control (cooling) This system control is performed to limit the inverter frequency in order to restrict high pressure’s abnormal increase and high-load operating prevention in the cooling mode. In accordance with the temperature of the outdoor heat exchanger temperature sensors (C1, C2), such controls are performed as to halting the operations of the indoor unit, decreasing the inverter frequency and restricting its increase, etc.

(See the chart below.) (a) Frequency will not be decreased less than 6 minutes after thermostat ON. (b) The threshold value is increased in accordance with the indoor load (differences of temperature).
