Abstract:
A solid state liquid-chilled bar unit for an aircraft galley includes a multilevel frame dimensioned to fit the galley and including stacked slots, each slot configured to fit a compartment. Warmer compartments include a liquid thermoelectric device (LTD) with "cold" and "hot" sides and a liquid heat exchanger (LHE) connected to the cold side. Scroll fans circulate air over a finned heat exchanger (on the LTD's hot side) to heat the compartment. Chiller compartments include LTDs with an LHE connected to the "hot" side, and may be bottle coolers or chiller drawers. Bottle coolers chill bottles or other containers via conductive contact with the LTD "cold" side, while chiller drawers chill air by circulating it over a finned heat exchanger on the "cold" side. Unchilled drawers store food, drink, or supplies at or near the ambient cabin temperature.

Abstract:
A method and apparatus for a turboprop-powered medium altitude long endurance (MALE) aircraft, comprising: a heat exchanger (51) comprising a heat-storage material, for example a heat-storage wax; and an air recirculation path (26); wherein the heat exchanger (51) is arranged to cool air recirculating around the air recirculation path (26) which is arranged to provide cooling to the MALE aircraft, for example to an equipment bay (18). The heat-storage material may be cooled by ground-based cooling apparatus when the aircraft is on the ground and/or by ram air when the aircraft is in flight. The heat-storage material may have a melting point selected so as to be rendered solid during ground- based cooling and/or ram air cooling, and/or selected so as to undergo melting whilst cooling the air recirculating around the air recirculation path (26).
