1. A system for conditioning air, the system comprising:
an enclosure in which the system is enclosed, the enclosure defining an air inlet and an air outlet,
a heat exchanger housed within the enclosure between the air inlet and the air outlet such that the air inlet is on one side of the heat exchanger and the air outlet is on another side of the heat exchanger, and an air filter between the air inlet and the heat exchanger, the air filter comprising zeolite,
the heat exchanger comprising a plurality of heat transfer tubes, a lower header that is an accumulation header and an upper header that is an outlet header, the plurality of heat transfer tubes extending between the accumulation header and the outlet header, wherein the heat exchanger defines an internal volume, and an external surface, and the heat exchanger is at least partially filled with two-phase liquid,
an air mover housed within the enclosure between the heat exchanger and the air inlet, the air mover is disposed in fluid communication with the air inlet and the air outlet, wherein the air mover is configured to urge a flow of air to be conditioned across the external surface of the heat exchanger,
a reactor within the enclosure, the reactor comprising reactor housing, an adsorbent material within the reactor housing, wherein the adsorbent material comprises zeolite beads, the reactor housing defining a rector inlet and a reactor outlet, the reactor inlet is fluidly coupled to the outlet header within the enclosure,
a vacuum pump within the enclosure, the vacuum pump comprising a vacuum pump inlet and a vacuum pump outlet, wherein the vacuum pump inlet is fluidly coupled to the reactor outlet within the enclosure,
wherein the reactor is configured to receive vapor from the two-phase water vacuum pressure from the vacuum pump or from natural convection, and
a system exhaust, wherein the vacuum pump outlet is in fluid communication with the system exhaust,
wherein:
the reactor is connected directly to the outlet header of the heat exchanger, the pump is connected directly to the outlet of the reactor; and
the reactor, the heat exchanger and the pump are located adjacent to each other within the enclosure.
