General

heat exchanger application

1.GENERAL

This application is aimed to be used in the Vacon liquid-cooled AC drive inside the Heat exchanger unit.

The idea with the application is to maintain a constant flow of coolant through the heat exchanger and through the Vacon liquid-cooled drive.

The user sets a certain speed for the pump of the heat exchanger unit that produces a sufficient flow through the Vacon liquid-cooled drives to keep them cooled. This speed is NOT regulated but fixed by a parameter set value.

The Vacon AC drive also handles the temperature of the water in the heat exchanger unit by regulating the valve that handles the coolant intake to the heat exchanger element (from the customer's system). This regulation is based on the temperature of the water in the pipes between the outlet of the heat exchanger pump and the inlet of the cooling element of the Vacon liquid-cooled drive.

The actual value of the temperature for the regulation comes from a sensor called FSA11. This is a type of flow switch that measures both the temperature of the coolant and the flow in the pipes. If there is not enough flow in the pipe the sensor gives a signal that tells the drive to stop due to insufficient flow.

Vacon NX AC drives can be connected to the Profibus DP using a fieldbus board. The AC drive can then be controlled, monitored and programmed from the Host system. Profibus fieldbus board (OPT-C5) is normally included in the delivery of Vacon NX liquid-cooled drive Heat Exchanger Solution. The Profibus fieldbus board must be installed in slot E on the control board of the AC drive. For more information on the Profibus fieldbus board, see Vacon OPTC3/C5 Profibus Option Board User Manual.

The standard delivery also includes I/O boards OPT-A1 (placed in slot A), OPT-A2 (placed in slot B) and OPT-B5 (placed in slot C or D). The application, however, offers you more signals than the standard set of I/O boards allows you to connect. If you wish to use one additional analogue input signal and/or two additional analogue output signals, we recommend you to order Vacon I/O board OPT-B4 and place it in the last free board slot (C or D).
