Desalination systems, apparatus, and related methods for use with saline fluids

A method for providing a desalination system, comprising:

• providing an HDH system including a humidifier and a dehumidifier that, together, are configured to process a first saline fluid to produce freshwater in the dehumidifier;
• providing an AD system including a first bed, a second bed, an evaporator, and a condenser that, together, are configured to process a second saline fluid to produce freshwater in the condenser;
• and
• operatively coupling the HDH system and the AD system together such that heat exhausted by the first or second bed is transferrable via the condenser from a first vapor, obtained from the second saline fluid, to the first saline fluid to drive the HDH system.

A desalination method, comprising:

• processing a first saline fluid via an HDH system to produce freshwater in a dehumidifier of the HDH system;
• processing a second saline fluid via an AD system to produce freshwater in a condenser of the AD system;
• transferring, via the condenser, heat exhausted by a first or second bed of the AD system from a vapor, obtained from the second saline fluid, to the first saline fluid to drive the HDH system;
• and
• providing a cooling effect to a refrigerant via an evaporator of the AD system.
