Abstract

Claims (26)

1 . A system comprising:

a reservoir defining an inlet and an outlet, and configured to hold a liquid received from the inlet;

a pump fluidically coupled to the reservoir and configured to pump the liquid from the reservoir to a fluid conditioning unit;

a sensor configured to observe an operational parameter; and

control logic configured to:

communicate a control signal to the pump;

receive a signal from the sensor; and

iteratively activate and deactivate the pump via the control signal until the signal received from the sensor comprises an indication that the fluid conditioning unit is filled with a liquid to a specified amount; and

a fill tank fluidically coupled to the reservoir; and

a second pump configured to pump liquid from the fill tank to the reservoir;

wherein the control logic is configured to communicate a second control signal to the second pump to activate and deactivate the second pump.

2 . The system of claim 1 , wherein the sensor comprises a temperature sensor, a pressure sensor, a liquid detection sensor, a flow sensor, or a fluid level sensor.

3 . The system of claim 1 , comprising a plurality of pumps fluidically coupled to the reservoir, each of the plurality of pumps configured to pump the liquid from the reservoir to the closed-loop liquid system.

4 . The system of claim 3 , wherein the control logic is configured to iteratively activate and deactivate each of the plurality of pumps.

5 . The system of claim 4 , wherein the control logic is configured to iteratively activate and deactivate each of the plurality of pumps sequentially.

6 . The system of claim 4 , wherein the control logic is configured to iteratively activate and deactivate each of the plurality of pumps concurrently.

7 . A system according to claim 1 , further comprising:

a baffle defining a corresponding plurality of apertures, wherein the baffle is positioned in the reservoir between the inlet and the outlet, wherein the baffle is oriented such that liquid received from the inlet passes through the plurality of apertures in the baffle before flowing through the outlet.

8 . The system of claim 7 , wherein the system further comprises a segment of conduit extending into the reservoir, the segment of conduit defining an arcuate segment such that an end of the segment of conduit is positioned lower, relative to gravity, than a centroid of the outlet.

9 . The system of claim 8 , wherein the segment of the conduit defines an end positioned distally from the outlet, wherein the end defines an aperture and wherein the aperture is oriented transversely relative to the outlet.

10 . The system of claim 8 , wherein the segment of the conduit defines an end positioned distally from the outlet, wherein the end defines an aperture and wherein the aperture is oriented transversely relative to the baffle.

11 . The system of claim 7 , wherein the baffle is a first baffle and the corresponding plurality of apertures is a first plurality of apertures, wherein the system further comprises a second baffle defining a second plurality of apertures.

12 . The system of claim 11 , wherein each of the first plurality of apertures and the second plurality of apertures has a corresponding hydraulic diameter characteristic of the respective plurality of apertures, wherein the hydraulic diameter characteristic of the first plurality of apertures differs from the hydraulic diameter characteristic of the second plurality of apertures.

13 . The system of claim 12 , wherein the baffles are arranged in order of decreasing hydraulic diameter along a direction extending from the inlet to the conduit segment.

14 . The system of claim 11 , wherein a hydraulic diameter characteristic of the first plurality of apertures is substantially equal of a hydraulic diameter characteristic of the second plurality of apertures.

15 . The system of claim 11 , wherein the plurality of apertures of the first baffle is offset from the plurality of apertures of the second baffle.
