A heat exchanger includes a shell and a plurality of tubes. The shell includes a heat exchange region in which a second refrigerant is to be introduced into the shell, so that a heat exchange occurs between the second refrigerant and a first refrigerant which flows through the plurality of tubes. The shell includes an inlet region through which the first refrigerant is introduced into the shell, a reverse region into which the first refrigerant is introduced, after the first refrigerant passes through the heat exchange region, and an outlet region into which the first refrigerant is introduced, after the first refrigerant passes through the reverse region and the heat exchange region, the first refrigerant being discharged out of the shell from the outlet region. The shell includes partition plates to divide the heat exchange region, the inlet region, the reverse region, and the outlet region.

A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes.

A condenser for a vapor compression system includes a shell, a tube bundle, and a tube support structure. The shell has a refrigerant inlet and a refrigerant outlet. The tube bundle includes a plurality of heat transfer tubes disposed inside the shell. Refrigerant discharged from the refrigerant inlet is supplied onto the tube bundle. The heat transfer tubes extend generally parallel to the longitudinal center axis of the shell. The tube support structure is configured and arranged to support the plurality of heat transfer tubes in the tube bundle within the shell. The tube support structure includes at least one tube support plate inclined relative to a vertical direction perpendicular to the longitudinal center axis of the shell.

A condenser for a vapor compression system includes a shell and a tube bundle. The shell has a refrigerant inlet and a refrigerant outlet. The tube bundle includes a plurality of heat transfer tubes disposed inside the shell. Refrigerant discharged from the refrigerant inlet is supplied onto the tube bundle. The heat transfer tubes extend generally parallel to the longitudinal center axis of the shell. The heat transfer tubes are arranged to form a first vapor passage extending generally vertically along a first passage lengthwise direction through at least some of the heat transfer tubes. The first vapor passage has a first minimum width measured perpendicularly relative to the first passage lengthwise direction and the longitudinal axis. The first minimum width is larger than a tube diameter of the heat transfer tubes, and the first minimum width is smaller than four times the tube diameter.

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