Abstract

Claims (25)

1. A contactor system comprising:

a plurality of contactor panels, each contactor panel including:

a frame member; and

a membrane array adapted to be received within the frame member, the membrane array defining a first end portion and a second end portion;

a first manifold in selective fluid communication with the first end portion of the membrane array of each contactor panel, the first manifold being adapted to direct a first fluid towards the membrane array of each contactor panel;

a second manifold in direct fluid communication with the second end portion of the membrane array of each contactor panel, the second manifold being adapted to receive the first fluid from the membrane array of each contactor panel;

a controller configured to provide selective fluid communication between the first manifold and the first end portion of the membrane array of each contactor panel;

a tank adapted to hold the first fluid therein;

an inlet conduit adapted to provide fluid communication between the tank and the first manifold;

an outlet conduit adapted to provide fluid communication between the tank and the second manifold; and

a chilling module fluidly coupled with the tank, the chilling module including:

a coolant reservoir;

a heat exchanger in fluid communication with the coolant reservoir and the tank; and

a coolant pump fluidly disposed between the tank and the heat exchanger.

2. The contactor system of claim 1 , wherein each contactor panel further includes:

a first conduit fluidly connecting the first manifold and the first end portion of the membrane array; and

a second conduit fluidly connecting the second manifold and the second end portion of the membrane array.

3. The contactor system of claim 2 , wherein each contactor panel further includes a valve assembly disposed in the first conduit and providing selective fluid communication between the first manifold and the first end portion of the membrane array.

4. The contactor system of claim 3 , wherein the controller is communicably coupled with the valve assembly of each contactor panel, and wherein the controller is configured to selectively control the valve assembly of at least one contactor panel.

5. The contactor system of claim 4 , wherein the controller is configured to selectively control the valve assembly of the at least one contactor panel based on at least one of a high thermal load location, a target temperature, a target humidity, and a temperature uniformity metric.

6. The contactor system of claim 4 , wherein the controller is configured to control the valve assembly to vary a flow rate of the first fluid flowing through the valve assembly of the at least one contactor panel.

7. The contactor system of claim 1 , wherein the frame member of each contactor panel defines a first headspace that provides fluid communication between the first manifold and the first end portion of the membrane array.

8. The contactor system of claim 1 , further comprising a pump fluidly disposed between the inlet conduit and the tank.

9. The contactor system of claim 1 , wherein the membrane array in each of the contactor panels includes at least one of a plurality of hollow fibers, a flat sheet membrane, and a combination thereof.

10. The contactor system of claim 9 , wherein each hollow fiber includes a capillary membrane.
