20. A method comprising:
arranging a liquid-to-air energy exchanger (LAEE) having a plurality of energy exchange (EX) circuits within or in proximity to an enclosed space, the LAEE comprising:
a single liquid panel having a plurality of liquid circuits through each of which a liquid is configured to flow, each of the liquid circuits corresponding to each of the plurality of EX circuits;
an air channel adjacent the liquid panel and through which air is configured to flow from an inlet of the LAEE to an outlet of the LAEE, the air channel extending adjacent all of the plurality of liquid circuits; and
a plurality of membranes connected to the liquid panel, each of the plurality of membranes corresponding to each of the plurality of liquid circuits and disposed between the respective liquid circuit and the air channel, wherein:
the plurality of liquid circuits comprises:
a first liquid circuit through which a first liquid is configured to flow; and
a second liquid circuit through which a second liquid is configured to flow, the second liquid circuit arranged downstream of the first liquid circuit in a direction of air flow through the LAEE;
the plurality of membranes comprises:
a first membrane connected to the liquid panel between the first liquid circuit and the air channel and forming a barrier between the first liquid and the air; and
a second membrane connected to the liquid panel between the second liquid circuit and the air channel and forming a barrier between the second liquid and the air; and
the plurality of EX circuits comprises:
a first EX circuit configured to exchange at least one of latent and sensible energy between the first liquid and the air through the first membrane; and
a second EX circuit configured to exchange at least one of latent and sensible energy between the second liquid and the air through the second membrane;
directing air through the air channel from the inlet of the LAEE to the outlet of the LAEE;
directing the first liquid through the first EX circuit;
directing the second liquid through the second EX circuit;
in the first EX circuit, exchanging at least one of latent and sensible energy between the first liquid flowing through the first liquid circuit and the air flowing through the air channel through the first membrane; and
in the second EX circuit, exchanging at least one of latent and sensible energy between the second liquid flowing through the second liquid circuit and the air flowing through the air channel through the second membrane.
