1. A cooling system comprising an ionic liquid dehumidification system comprising:
a) an ionic liquid desiccant composition comprising:
i) an ionic liquid desiccant;
ii) water;
b) a conditioner comprising:
i) a conditioner ionic liquid desiccant conduit having:
an ionic liquid desiccant inlet;
an ionic liquid desiccant outlet;
wherein the ionic liquid desiccant composition flows through the conditioner ionic liquid desiccant conduit;
ii) a conditioner fluid conduit having:
a conditioner fluid inlet;
a conditioner fluid outlet;
wherein a conditioner fluid flows through the conditioner fluid conduit; and
iii) an impermeable exchange membrane configured between the conditioner ionic liquid desiccant conduit and the conditioner fluid conduit;
wherein the conditioner fluid comprises moisture that is transferred through the conditioner impermeable exchange membrane to the ionic liquid desiccant flowing through the conditioner ionic liquid desiccant conduit;
c) a regenerator;
i) a regenerator ionic liquid desiccant conduit having:
an ionic liquid desiccant inlet;
an ionic liquid desiccant outlet;
wherein the ionic liquid desiccant composition flows through the regenerator ionic liquid desiccant conduit;
ii) a regenerator fluid conduit having:
a regenerator fluid inlet;
a regenerator fluid outlet;
wherein the regenerator fluid flows through the regenerator fluid conduit;
i) an impermeable exchange membrane configured between the regenerator ionic liquid desiccant conduit and the regenerator fluid conduit;
d) a compressor that heats the ionic liquid desiccant so that ionic liquid desiccant is heated to a temperature greater than the temperature of ionic liquid desiccant in the conditioner;
wherein the ionic liquid desiccant flowing through the regenerator comprises moisture absorbed from the conditioner that is transferred through the regenerator impermeable exchange membrane to the regenerator fluid flowing through the regenerator fluid conduit;
wherein the ionic liquid desiccant composition has a lower moisture content at the conditioner fluid outlet than at the conditioner fluid inlet and wherein the ionic liquid desiccant composition has a lower temperature at the conditioner fluid outlet than at the conditioner fluid inlet.
