Compartment cooling loss identification for efficient system operation

摘要

A galley cooling system comprises a plurality of galley cooling units (40) each to be associated with separate galleys. A sensor (44) senses a condition within each of the galleys. A control determines whether a sensed condition is indicative of efficient operation of a particular galley cooling unit, and the control is operable to decrease cooling capacity delivered to a galley cooling unit which is experiencing inefficient operation. An aircraft galley system incorporating the above cooling unit, and a method of operating a galley cooling unit are also disclosed and claimed.
