Abstract
An aircraft galley refrigeration system is provided which, in one embodiment, includes: first and second galleys; a first chiller for providing a first heat transfer fluid to the first galley; a second chiller for providing a second heat transfer fluid to the second galley; and a heat exchanger including a first circuit and a second circuit, the first circuit connecting the first galley with the first chiller, and the second circuit connecting the second galley with the second chiller. In another embodiment, the system includes a first cooling subsystem with a first heat transfer fluid, a second cooling subsystem with a second heat transfer fluid, and a heat exchanger that thermally couples the first and second cooling subsystems for distributing heat between the first and second heat transfer fluids.
