Systems and methods for modulating temperature and humidity of an enclosed space

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

• a first conditioning system configured to condition a first air stream and direct the conditioned first air stream into the enclosed space, the first conditioning system comprising:
• a first plenum through which the first air stream is configured to be directed into the enclosed space;
• a wet coil in the first plenum;
• and
• a first liquid-to-air heat exchanger (LAHX1) downstream of the wet coil in the first plenum;
• a second conditioning system fluidically connected to the first conditioning system and configured to condition one or more liquid streams, the second conditioning system comprising:
• a second plenum through which a second air stream is configured to be directed;
• a liquid-to-air membrane energy exchanger (LAMEE) in the second plenum and comprising a plurality of liquid and air channels, adjacent pairs of which are separated by a permeable membrane;
• and
• a second liquid-to-air heat exchanger (LAHX2) downstream of the LAMEE in the second plenum;
• and
• a liquid transport system configured to transport the one or more liquid streams in and between the first conditioning system and the second conditioning system.
