A refining system includes a Peltier heat exchanger, an evaporation tank, and a nozzle. The Peltier heat exchanger is configured to receive unrefined liquid and comprising a Peltier cell. The nozzle is positioned within the evaporation tank and configured to receive unrefined liquid from the Peltier heat exchanger and provide unrefined liquid into the evaporation tank such that vapor is formed. The Peltier heat exchanger is configured to receive vapor from the evaporation tank while simultaneously receiving unrefined liquid. The Peltier cell is configured to heat unrefined liquid within the Peltier heat exchanger and cool vapor within the Peltier heat exchanger simultaneously.

A flatpack air chiller device is disclosed. In embodiments, the air chiller device includes a primary chiller or pre-chiller subsystem and a secondary or main chiller subsystem within a housing. The pre-chiller subsystem receives and chills ambient air via cold-side contact with a primary thermoelectric device and directs the pre-chilled ambient airstream to the hot side of a secondary thermoelectric device. The secondary or main chiller subsystem is connected to a recirculating air stream, e.g., circulating through the interior airspaces, compartments, or bays of a galley structure. The pre-chilled ambient airstream absorbs heat from the secondary hot side to progressively chill the recirculating air stream, which is in contact with the cold side of the secondary thermoelectric device before recirculation back into the galley structure interior.

A headgear apparatus having a shell, an air flow structure, a thermoelectric system, a connector, and a condensate wick. The air flow structure is coupled to the shell and the thermoelectric system is configured to produce a stream of air. The thermoelectric system has a housing having at least one air inlet, a first and a second air outlet, a least one blower and at least one thermoelectric heat pump. The first air outlet provides the stream of cooled air to the air flow structure and the second air outlet vents hot air produced by the heat pump to outside the apparatus. The connector is configured to connect the first air outlet of the thermoelectric system housing to the air flow structure and the condensate wick is configured to collect condensation formed by the heat pump and evaporate the collected condensation using the hot air produced by the heat pump.
