Cooling systems and related methods

A cooling system, comprising:

• a cooling unit comprising:
• a thermally conductive housing adapted to contain a vaporizable liquid therein and enable transfer of thermal energy from an exterior of the thermally conductive housing to the vaporizable liquid, the transfer converting the vaporizable liquid into a vapor,
• a fluid inlet adapted to receive a feed of vaporizable liquid for introducing the vaporizable liquid into the thermally conductive housing, and
• a vapor outlet;
• a first adsorbent unit comprising:
• a housing containing a reusable solid adsorbent material therein, the housing comprising:
• a metal region defining a second side of the housing, and
• a transparent region facing the reusable solid absorbent material the transparent region of the housing defining a transparent first side of the housing positioned opposite the second side,
• a plurality of heat spreaders disposed in the solid absorbent material and thermally coupled with the metal region, the transparent region enabling solar heating of the reusable solid adsorbent material through the transparent region to regenerate the reusable solid adsorbent material,
• a vapor inlet configured to be removeably coupled to the vapor outlet of the cooling unit, the vapor inlet enabling the reusable solid adsorbent material to adsorb the vapor from the cooling unit, and
• a regeneration port sealed by a removable end cap, the regeneration port adapted to be removeably coupled to a vapor inlet of a second adsorbent unit when the end cap is removed to permit the vapor from the cooling unit to be adsorbed by the second adsorbent unit;
• and
• a vacuum pump configured to be placed in removable fluid communication with at least one of the cooling unit and the first adsorbent unit, the vacuum pump adapted to generate negative pressure within the cooling unit and the first adsorbent unit.
