Abstract
A method for controlling an operation of an ice-making machine configured to make ice by cooling a medium to be cooled, through heat exchange with a refrigerant. The method includes increasing an evaporation temperature of the refrigerant to be supplied to the ice-making machine when a drive current for an ice scraper of the ice-making machine is more than a first current value.
Claims6
A method for controlling an operation of an ice-making machine configured to make ice by cooling a medium to be cooled, through heat exchange with a refrigerant in a refrigerant circuit including a compressor,
- the method comprising:
- increasing an evaporation temperature of the refrigerant to be supplied to the ice-making machine when a drive current for an ice scraper of the ice-making machine is more than a first current value,
- stopping the operation of the compressor and continuing the operation of the ice scraper when the drive current is more than a second current value that is larger than the first current value,
- restarting the operation of the compressor when the drive current decreases to a predetermined value.

A method for controlling an operation of an ice-making machine configured to make ice by cooling a medium to be cooled, through heat exchange with a refrigerant in a refrigerant circuit including a compressor,
- the method comprising:
- increasing an evaporation temperature of the refrigerant to be supplied to the ice-making machine when a pressure difference between a pressure of the medium to be cooled at an inlet of the ice-making machine and a pressure of the medium to be cooled at an outlet of the ice-making machine is more than a first pressure value,
- stopping the operation of the compressor and continuing the operation of the ice scraper when the pressure difference is more than a second pressure value that is larger than the first pressure value,
- restarting the operation of the compressor when the pressure difference decreases to a predetermined value.
