Abstract

The invention relates to a method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system. A user selects on the control unit, among the plurality of devices of the refrigeration system, a first device to configure. Information of valid configurable operating parameters of the first device is provided on the control unit. The user selects at least one of the valid configurable operating parameters of the first device, thereby configuring the first device. Information stored about operating parameters of other devices of the refrigeration system, based on the configuration of the first device, is then provided on the control unit. Finally, the user confirms, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices. The invention also relates to a control unit and a refrigeration system.

First claim

The invention claimed is:

1. A method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system, the method comprising the steps of:
selecting among the plurality of devices of the refrigeration system, on the control unit, a first device to configure,
providing, on the control unit, information of valid configurable operating parameters of the first device;
selecting at least one of the valid configurable operating parameters of the first device, thereby configuring the first device;
providing, on the control unit, information of operating parameters of other devices of the refrigeration system, based on the configuration of the first device,
the information of the set of operating parameters of the other devices being based on stored data of the plurality of devices of the refrigeration system,
confirming, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices,
providing additional devices, not controlled by the control unit controlling the first device, where the additional devices comprise an evaporator with refrigerant passed to an inlet of the evaporator,
designating a condenser as the first device controlled by the control unit, where a pressure of the refrigerant at the outlet of the condenser is configured by the control unit so that the temperature of the refrigerant at the inlet of the evaporator is between plus 10 degrees Celsius and minus 30 degrees Celsius, and
configuring operating parameters of the one or more of the other devices controlled by the control unit based on the configuration of outlet pressure of the refrigerant from the condenser.

2. The method according to claim 1 , wherein the method comprises the following steps preliminary to the step of confirming on the control unit one or more parameters of one or more of the other devices:
providing, on the control unit, information of valid configurable parameters of one or more of the other devices, and
selecting at least one of the valid configurable parameters of the one or more other devices, thereby configuring the one or more other devices.

3. The method according to claim 1 , wherein the step of selecting, on the control unit, the first device includes
providing information, on the control unit, of a plurality of devices to be configured of at least a part of the refrigeration system, and
the step of selecting at least one valid configurable operating parameter of the first device is performed by designating the first device and/or by designating a parameter.

4. The method according to claim 3 , where the selection of the first device is performed by one or more of the following actions: touching on a touch-screen display of the control unit a row, column or cell naming the first device, or speaking out to a microphone of the control unit a naming of the first device.

5. The method according to claim 1 , where the step of selecting, on the control unit, the first device includes displaying a drawing of a plurality of devices to be configured of at least part of the refrigeration system, and where the first device is displayed in the drawing of the plurality of devices of the part of the refrigeration system, and where selecting the first device is performed by designating the first device in the drawing.

6. The method according to claim 5 , where the selection of the first device is performed by one or more of the following actions: touching the first device in the drawing on a touch screen of the control unit, or speaking out to a microphone of the control unit a naming of the first device as named in the drawing.

7. The method according to claim 1 , wherein the first device is a receiver of the refrigeration system, and where the at least one parameter to be selected is a pressure of refrigerant within the receiver.

8. A method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system, the method comprising the steps of:
selecting among the plurality of devices of the refrigeration system, on the control unit, a first device to configure,
providing, on the control unit, information of valid configurable operating parameters of the first device;
selecting at least one of the valid configurable operating parameters of the first device, thereby configuring the first device;
providing, on the control unit, information of operating parameters of other devices of the refrigeration system, based on the configuration of the first device,
the information of the set of operating parameters of the other devices being based on stored data of the plurality of devices of the refrigeration system,
confirming, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices,
providing additional devices, not controlled by the control unit controlling the first device, where the additional devices comprise an evaporator with refrigerant passed to an inlet of the evaporator,
designating a receiver as the first device controlled by the control unit, where a pressure of the refrigerant inside the receiver is configured by the control unit so that the temperature of refrigerant at the inlet of the evaporator is between plus 10 degrees Celsius and minus 30 degrees Celsius, and
configuring operating parameters of the one or more of the other devices controlled by the control unit based on the configuration of the pressure of the refrigerant inside the receiver.

9. The method according to claim 8 , wherein the method comprises the following steps preliminary to the step of confirming on the control unit one or more parameters of one or more of the other devices:
providing, on the control unit, information of valid configurable parameters of one or more of the other devices, and
selecting at least one of the valid configurable parameters of the one or more other devices, thereby configuring the one or more other devices.

10. The method according to claim 8 , wherein the step of selecting, on the control unit, the first device includes
providing information, on the control unit, of a plurality of devices to be configured of at least a part of the refrigeration system, and
the step of selecting at least one valid configurable operating parameter of the first device is performed by designating the first device and/or by designating a parameter.

11. The method according to claim 10 , where the selection of the first device is performed by one or more of the following actions: touching on a touch-screen display of the control unit a row, column or cell naming the first device, or speaking out to a microphone of the control unit a naming of the first device.

12. The method according to claim 8 , where the step of selecting, on the control unit, the first device includes displaying a drawing of a plurality of devices to be configured of at least part of the refrigeration system, and where the first device is displayed in the drawing of the plurality of devices of the part of the refrigeration system, and where selecting the first device is performed by designating the first device in the drawing.

13. The method according to claim 12 , where the selection of the first device is performed by one or more of the following actions: touching the first device in the drawing on a touch screen of the control unit, or speaking out to a microphone of the control unit a naming of the first device as named in the drawing.

14. The method according to claim 8 , wherein the first device is a receiver of the refrigerati
