Peak Cut Control
Outline
Based on the indoor heat exchanger intermediate temperature signal sent from the indoor unit,
the compressor output frequency is regulated to lower the compressor capacity in order to
prevent an abnormal increase of the high pressure.
Details
Zones are produced based on the heat exchanger temperature signal sent from the BP unit
(indoor unit), and the peak-cut control prevents an abnormal rise of the high pressure.
A change of 2 Hz is made when each zone fluctuates.
The reset zone is set for 30 seconds when the operation mode is changed, for 30 seconds when
the number of operating room units increase, and for 20 seconds when the number of operating
room units decrease.
With each operation of the HPS operation counter, the above zone judgment temperature is
decreased by 2°C.
With each operation of the peak-cut abnormal operation counter , the above drooping speed is
increased by 1 Hz.
Drooping speed : 2Hz/40sec
