Heat Exchanger Modules

Заказные данные
(8)

Heat Exchanger Modules are used to dissipate the power loss from the converter. They comprise a deionized water circuit on the converter side and a raw water circuit on the plant side.

The hot deionized water in the circuit on the converter side passes through a maintenance-free circulating pump into the water/water plate-type heat exchanger. This is made of stainless steel and connected to the raw water circuit on the plant side. The deionized water is cooled there by the raw water of the outer circuit and flows back into the drive.

The closed converter-side deionized water circuit is filled with coolant in accordance with the requirements in section "Cooling circuit and coolant quality" and deaerated before commissioning. The pressure is maintained by means of an expansion chamber. Any residual air that arises in the circuit during operation is removed via automatic vents.

To avoid condensation at excessively low coolant temperatures, a three-way valve for controlling the coolant temperature is installed.

Heat Exchanger Modules are available for the following voltages and cooling power ratings:

Line voltage	Cooling power
380 ... 415 V 3 AC, 50 Hz	32 ... 110 kW
660 ... 690 V 3 AC, 50/60 Hz	32 ... 110 kW

Heat Exchanger Modules for other line voltages (up to 480 V or as of 500 V) and for 60 Hz are available on request.

Дизайн

The deionized water is monitored by the drive itself to ensure intrinsic protection. The operating status is signaled to the drive.

Heat Exchanger Modules contain the following components as standard:

1 pump
1 stainless steel plate-type heat exchanger
1 three-way valve
Filter, expansion chamber, vent, safety valve, pressure sensors, pressure display, temperature sensor, TM31 Terminal Module, LOGO control.

Note:

Heat Exchanger Modules can only be located at the beginning or end of a cabinet row for technical reasons.

Технические данные

The Heat Exchanger Modules must be selected appropriately for the required cooling power and the required volume flow of coolant in the converter-side deionized water circuit. The values stated in the technical specifications of the Cabinet Modules for the heat loss dissipated into the coolant must be summated. The total value is then the required cooling power.

The volume flow of coolant stated in the technical data of the Cabinet Modules must also be added.

If either of the two total values exceeds the values defined in the technical specifications of the Heat Exchanger Module (cooling power and volume flow of coolant for converter-side deionized water), the next larger Heat Exchanger Module must be selected.
