Using liquid to air membrane energy exchanger for liquid cooling

A conditioning system for controlling conditions in an enclosed space, the conditioning system comprising:

• a cooling system disposed outside of the enclosed space, the cooling system comprising:
• a scavenger air plenum having an air inlet and outlet, the scavenger air plenum configured to direct scavenger air in an air flow path from the air inlet to the air outlet;
• a liquid to air membrane energy exchanger (LAMEE) arranged inside the scavenger air plenum in the air flow path, the LAMEE comprising a cooling fluid flow path separated from the air flow path by a membrane, the LAMEE configured to use the scavenger air to evaporatively cool a cooling fluid in the cooling fluid flow path, a temperature of the cooling fluid at a fluid outlet of the LAMEE is lower than a temperature of the cooling fluid at a fluid inlet of the LAMEE;
• a first cooling unit arranged inside the scavenger air plenum between the air inlet and the LAMEE, the first cooling unit configured to condition the scavenger air prior to the scavenger air entering the LAMEE;
• a second cooling unit arranged inside the scavenger air plenum between the LAMEE and the air outlet, the second cooling unit configured to reduce a temperature of the cooling fluid before the cooling fluid enters the LAMEE at the fluid inlet;
• and
• one or more bypass dampers configured to permit scavenger air to enter or exit the air flow path at one or more locations between the air inlet and outlet;
• and
• a cooling fluid circuit connected to the cooling fluid flow path of the LAMEE and extending from the scavenger air plenum into the enclosed space, the cooling fluid circuit configured to provide cooling to the enclosed space without moving air from the enclosed space through the cooling system.
