Abstract

In order to an initialising system for a refrigerant compressor unit, including a refrigerant compressor, an electrical drive motor for the refrigerant compressor and a compressor controller that determines the voltage and speed of the drive motor on the basis of sets of configuration parameters loaded into this compressor controller and controls the drive motor accordingly, wherein the initialising system has a compressor data memory, in which compressor data relating to respectively possible refrigerant compressors are stored, and a motor data memory, in which motor data relating to possible drive motors are stored, wherein the initialising system has a processor for performing the initialisation, a display unit and an input unit, wherein during initialisation the display unit and the input unit serve to determine the refrigerant compressor and the drive motor, and wherein the processor uses the compressor data of the determined refrigerant compressor and uses the motor data of the determined drive motor to generate compressor configuration parameters and motor configuration parameters and loads them into the compressor controller for the purpose of operating the drive motor.

First claim

2. The method according to claim 1 , wherein a list of compressors is generated from the stored compressor data and displayed on the display unit.

3. The method according to claim 2 , wherein one of the refrigerant compressors in the compressor list is determined using the input unit.

4. The method according to claim 1 , wherein the compressor configuration parameters that belong to the determined refrigerant compressor are generated using the compressor data.

5. The method according to claim 4 , wherein the compressor configuration parameters are loaded into the compressor controller after confirmation thereof using the input unit.

6. The method according to claim 1 , wherein a list of motors is compiled from the motor data and displayed on the display unit.

7. The method according to claim 1 , wherein suitable drive motors are selected from the motor data using the compressor data for the determined refrigerant compressor and are displayed in the motor list on the display unit.

8. The method according to claim 6 , wherein a drive motor from the motor list is determined using the input unit.

9. The method according to claim 8 , wherein the motor configuration parameters that belong to the determined drive motor are generated using the motor data.

10. The method according to claim 9 , wherein the motor configuration parameters are loaded into the compressor controller after confirmation thereof using the input unit.

11. The method according to claim 1 , wherein a list of refrigerants is generated from refrigerant data stored in a refrigerant data memory and is displayed on the display unit.

12. The method according to claim 11 , wherein a refrigerant from the refrigerant list is determined using the input unit.

13. The method according to claim 1 , wherein the refrigerant configuration parameters that belong to the determined refrigerant are compiled using the refrigerant data.

14. The method according to claim 13 , wherein selection parameters are extracted from the refrigerant configuration parameters and displayed on the display unit.

15. The method according to claim 14 , wherein the displayed selection parameters are determined using the input unit.
