An assembly is provided for an aircraft propulsion system. This assembly includes a gas turbine engine and a vapor absorption refrigeration system. The gas turbine engine includes a turbine section. The vapor absorption refrigeration system is configured to be driven by waste heat energy received from the turbine section. The vapor absorption refrigeration system includes a condenser.

There is provided an absorption chiller including: a control unit configured to control opening and closing of the first control valve and an operation of the first pump, and a second supply flow path configured to supply the liquid inside the evaporator into the absorber; a second control valve opening and closing the second supply flow path; and a second pump configured to generate power to supply the liquid inside the evaporator into the absorber. After an operation of the absorption chiller is stopped, the control unit is configured to open the first control valve and operate the first pump such that a liquid inside the evaporator is mixed with the absorption liquid. Further, before the first control valve is opened and the first pump is operated, the control unit is configured to open the second control valve and operate the second pump.

A cooling system utilizes an organic ionic salt composition for dehumidification of an airflow. The organic ionic salt composition absorbs moisture from an inlet airflow to produce an outlet airflow with a reduce moisture from that of the inlet airflow. The organic ionic salt composition may be regenerated, wherein the absorbed moisture is expelled by heating with a heating device. The heating device may be an electrochemical heating device, such as a fuel cell, an electrochemical metal hydride heating device, an electrochemical heat pump or compressor, or a condenser of a refrigerant cycle, which may utilize an electrochemical pump or compressor. The efficiency of the cooling system may be increased by utilization of the waste heat the cooling system. The organic ionic salt composition may circulate back and forth or in a loop between a conditioner, where it absorbs moisture, to a regenerator, where moisture is desorbed by heating.

A method includes: providing an absorber material including: a casing; and superabsorbent particles arranged therein, and using the absorber material to absorb and/or distribute liquids in an actively and/or passively cooled current-carrying system including an actively and/or passively cooled power storage system. The casing has at least two plies arranged in a planar fashion on one another. Regions of the at least two plies are connected to one another by at least one seam such that the casing is segmented in a form of pockets separated from one another. At least some of the pockets have the superabsorbent particles.
