Abstract

A chilled water plant includes a communications bus, chilled water plant devices connected to the communications bus, and a chiller device connected to the communications bus. The chiller device is configured to detect the chilled water plant devices connected to the communications bus during a commissioning process, determine device status modules based at least in part on a type of each of the chilled water plant devices, control an operation of the chilled water plant, and display a user interface containing the device status modules.

Claims

1. A chilled water plant comprising:

a communications bus;

a plurality of chilled water plant devices connected to the communications bus; and

a chiller device connected to the communications bus, wherein the chiller device is configured to;

detect, by a processing circuit of the chiller device, the plurality of chilled water plant devices connected to the communications bus during a commissioning process;

determine, by the processing circuit of the chiller device, device status modules based at least in part on a type of each of the plurality of chilled water plant devices;

control an operation of the chilled water plant; and

display, by a display panel of the chiller device, a user interface containing the device status modules.

2. The chilled water plant of claim 1, wherein the plurality of chilled water plant devices includes a cooling tower.

3. The chilled water plant of claim 1, wherein the plurality of chilled water plant devices includes a chilled water pump.

4. The chilled water plant of claim 1, wherein the plurality of chilled water plant devices includes a condenser water pump.

5. The chilled water plant of claim 1, wherein the plurality of chilled water plant devices includes an isolation valve.

6. The chilled water plant of claim 1, wherein the user interface further comprises indicator lights, the indicator lights configured to be selectively illuminated based on the type of each of the plurality of chilled water plant devices.

7. The chilled water plant of claim 6, wherein the indicator lights are configured to be selectively illuminated to indicate a future operational status of the plurality of chilled water plant devices.

8. The chilled water plant of claim 1, wherein the device status modules are configured to display at least one of a device serial number, a current device status, and a current device speed.

9. The chilled water plant of claim 1, wherein the chiller device is further configured to remove device status modules from the user interface based on a determination that a number of chilled water plant devices connected to the communications bus has decreased.

10. The chilled water plant of claim 1, wherein the chiller device is further configured to add device status modules to the user interface based on a determination that a number of chilled water plant devices connected to the communications bus has increased.

11. A method for dynamically displaying properties of a chilled water plant, the method comprising:

detecting, by a processing circuit of a chiller device, a plurality of chilled water plant devices connected to a communications bus of the chilled water plant during a commissioning process;

determining, by the processing circuit of the chiller device, device status modules based at least in part on a type of each of the plurality of chilled water plant devices; and

displaying, by a display panel of the chiller device, a user interface containing the device status modules.

12. The method of claim 11, wherein the plurality of chilled water plant devices includes a cooling tower.

13. The method of claim 11, wherein the plurality of chilled water plant devices includes a chilled water pump.

14. The method of claim 11, wherein the plurality of chilled water plant devices includes a condenser water pump.

15. The method of claim 11, wherein the plurality of chilled water plant devices includes an isolation valve.

16. The method of claim 11, wherein the user interface further comprises indicator lights, the indicator lights configured to be selectively illuminated based on the type of each of the plurality of chilled water plant devices.

17. The method of claim 16, wherein the indicator lights are configured to be selectively illuminated to indicate a future operational status of the plurality of chilled water plant devices.

18. The method of claim 11, wherein the device status modules are configured to display at least one of a device serial number, a current device status, and a current device speed.

19. The method of claim 11, further comprising removing device status modules from the user interface based on a determination that a number of chilled water plant devices connected to the communications bus has decreased.

20. The method of claim 11, further comprising adding device status modules to the user interface based on a determination that a number of chilled water plant devices connected to the communications bus has increased.

21. A chilled water plant comprising:

a communications bus;

at least one of a cooling tower, a chilled water pump and a condenser water pump connected to the communications bus; and

a chiller device connected to the communications bus, wherein the chiller device is configured to;

detect, by a processing circuit of the chiller device, a number of operational devices connected to the communications bus, the operational devices comprising at least one of a cooling tower, a chilled water pump and a condenser water pump;

determine, by the processing circuit of the chiller device, a number of device status cells based on the number of operational devices;

control, by the processing circuit of the chiller device, an operation of the chilled water plant; and

display, by a display panel of the chiller device, a user interface containing the number of device status cells.

22. The chilled water plant of claim 21, wherein the device status cells are configured to display at least one of a device serial number, a current device status, and a current device speed.

23. The chilled water plant of claim 21, wherein the chiller device is further configured to:

determine a number of indicator lights based on the number of operational devices; and

display the number of indicator lights on the user interface.

24. The chilled water plant of claim 23, wherein the chiller device is further configured to modify at least one of the number of device status cells and the number of indicator lights in response to a determination that the number of operational devices has changed.
