Starting Frequency Control
Outline
The inverter compressor will start up with a limited fixed frequency value for a specified period
of time in order to prevent liquid back to the compressor, and to limit the starting current.
General
The normal starting control time is 2~3 minutes. The maximum starting frequency control time is
limited to 10 minutes.
During compressor start-up, a pressure difference will be build up in order to have sufficient
pressure difference for the 4-way valve to change over.
Graph
Ending condition
The starting control will be terminated when the low pressure value < 6 bar or when the
maximum starting time of 10 minutes has been reached in case the low pressure value stays >
6 bar.
