Patent ID: 8584485

Claim:
Aircraft cooling system evaporator arrangement, comprising: an evaporation device for exchanging heat between a refrigerant and a coolant, the evaporation device including at least four evaporators which are hydraulically separate from one another with respect to the flow of coolant; at least one feed line for supplying refrigerant to the evaporation device, the at least four evaporators arranged such that refrigerant flows from the at least one feed line into first and second ones of the at least four evaporators, refrigerant from the first evaporator flows into and through a third one of the at least four evaporators, and refrigerant from the second evaporator into and through a fourth one of the at least four evaporators, the first and third evaporators defining a first pair of evaporators arranged parallel to a second pair of evaporators defined by the second and fourth evaporators; and two mutually independent coolant circuits, wherein each coolant circuit includes at least two supply lines arranged to be hydraulically separate from one another, the at least two supply lines of a first one of the coolant circuits comprising a first coolant supply line supplying coolant to one of the evaporators in the first pair of evaporators and a second coolant supply line supplying coolant to one of the evaporators in the second pair of evaporators, the at least two supply lines of a second one of the coolant circuits comprising a first coolant supply line supplying coolant to the other of the evaporators in the first pair of evaporators and a second coolant supply line supplying coolant to the other of the evaporators in the second pair of evaporators.
