Compressor Body Protection Control
This compressor body protection control is used to protect the compressor internal temperature
against an error or transient increase of compressor body temperature.
Contents
The following control is performed for each compressor of single unit as well as multi units.
6.5
Inverter Protection Control
Inverter current protection control and radiation fin temperature control are performed to prevent
tripping due to an error, or transient inverter overcurrent, and fin temperature increase.
In the case of multi-outdoor-unit system, each inverter compressor performs these controls in the
following sequence.
Inverter overcurrent protection control
Perform the following control of integrated as well as multi units for each inverter compressor.
