A system and method are provided for refrigerating at least one enclosure (11), such as an aircraft galley cart. The system includes at least one air-to-liquid heat exchanger (18), an eutectic thermal battery (12), a liquid-to-direct heat exchanger (14) and at least one liquid-to-direct heat pump (16). The air-to-liquid heat exchangers (18) are in thermal communication with the interiors of the enclosures (11). The thermal battery (12) is in fluid communication with the air-to-liquid heat exchangers (18) via a first coolant loop (L1). The liquid-to-direct heat exchanger (14) and the liquid-to-direct heat pumps (16) are in fluid communication with the eutectic thermal battery (12) via a second coolant loop (L2), and in thermal communication with a cold heat sink, such as an aircraft fuselage skin structure. The system can controllably operate in direct passive, indirect passive, direct active and/or an indirect active modes whereby a coolant can selectively flow in the first (L1) and/or second (L2) coolant loops to thereby refrigerate the enclosures (11). |
