  • a temperature signal Ti exceeds the fourth temperature level TL4 the compressor 14 is switched-off for safety reasons.
  • the compressor 14 is controlled by speed.
  • the compressor 14 may be controlled by power (not depicted) in a similar manner.

  • the compressor power is controlled at the beginning of the drying cycle a predetermined value of power is supplied to the compressor 14 which helps in increasing the refrigerant pressure in the refrigerant loop branch between the compressor 14 and the expansion device 16 to reach nominal or desired working conditions of the heat pump system 4 as soon as possible.
  • the compressor speed decreases because as refrigerant temperature and pressure increases. With an increasing refrigerant pressure, a higher portion of the motor power is consumed for the compressing work and consequently the rotation speed decreases.

  • a monitored temperature signal Ti exceeds a first temperature level TL1 the cooling air blower 24 is switched-on and remains activated.
  • the detected first temperature signal Ti falls below a switch-off temperature level TL1' - which is lower than the first temperature level TL1 - the blower 24 is switched-off. I.e. it is ensured that the cooling air blower 24 is switched-off at a save temperature level.

  • the compressor 14 In temperature region I, i.e. the temperature region up to the second temperature level TL2, the compressor 14 is operated at target power as described above with respect to Fig. 5 . In temperature regions II and III speed target control is implemented as described above. When a temperature signal Ti exceeds the second temperature level TL2 compressor speed is reduced linearly with the rising temperature signal Ti. With decreasing compressor speed the compressor power is also reduced.

  • the compressor speed is linearly increased with decreasing temperature until the temperature signal Ti is below the second temperature level TL2.

  • the cooling blower 24 is switched-off while the compressor is operated at target power.
  • a temperature hysteresis may be provided for switching the blower motor 34 on at the higher temperature TL1 and off at the lower temperature TL1'.
  • the compressor safety deactivation is set to the higher hysteresis temperature TL4 and the compressor activation in the high temperature regime III is set at the lower hysteresis temperature TL4'. In both cases a permanent switching on and off of the blower motor 34 and the compressor motor 14 is avoided.
