REFRIGERATING MACHINE AND CONTROL METHOD THEREFOR

摘要

This refrigerating machine is equipped with: a turbocompressor which compresses a refrigerant; a condenser which is equipped with one or more pipe groups (31) configured from a plurality of heat transfer pipes (30) through which cooling water flows, and condenses the refrigerant compressed by the turbocompressor; an expansion valve which causes the refrigerant condensed by the condenser (4) to expand; an evaporator which causes the refrigerant expanded by the expansion valve to evaporate; a temperature sensor (37) which detects cooling water exit temperature, which is the temperature of the cooling water flowing from at least one of the heat transfer pipes (30) constituting the pipe group(s) (31); and a control unit which determines, on the basis of the detection temperature of the temperature sensor (37), air bleeding start conditions for starting an air bleeding operation to bleed and discharge air to the outside.
