A liquid desiccant system including a high desorber, a low desorber, and an absorber that are in fluid communication with a working solution, where the high desorber provides rejected water vapor from the working fluid for condensation in a condenser of the low desorber that provides heat for rejection of additional water from the working solution in the low desorber effectively multiplying the heat provided for desorption. The low desorber provided the concentrated working solution to the absorber where water from ambient air is condensed into the concentrated working solution to provide a dilute working solution within a working solution conduit of the absorber that is thermally coupled to an internal cooler of the absorber. In some embodiments, the working solution can be an aqueous solution of at least one ionic liquid.

The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that connects a bypass collection pipe that guides an absorbent flowing back into the second regenerator to be collected into an absorber to a second collection pipe, in order to prevent the water level of the second regenerator from being raised as the absorbent cannot be collected by the absorber and flows back to the second regenerator, due to the pressure difference between an absorbent separated from the first regenerator and collected into the absorber through the first collection pipe, and an absorbent separated from the second regenerator and collected into the absorber through the second collection pipe.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.
