Abstract:
1. Aircraft cooling system evaporator arrangement, comprising: at least two mutually independent coolant circuits each carrying a coolant; at least two evaporation devices arranged to be hydraulically parallel to and hydraulically separate from each other for enabling an exchange of heat between the coolant in each of the at least two coolant circuits and a refrigerant; at least two supply lines for supplying refrigerant to the evaporation devices; at least two discharge lines for discharging refrigerant from the evaporation devices; a different one of the at least two evaporation devices, a different one of the at least two supply lines and a different one of the at least two discharge lines being assigned to each of the at least two coolant circuits; the supply lines and discharge lines assigned to various coolant circuits being arranged to be hydraulically separate in each instance; furthermore at least one refrigerant sensor for monitoring a refrigerant state being assigned to each of the discharge lines; and the evaporator arrangement further including an expansion valve which for the purpose of controlling streams of refrigerant through the supply lines is designed to be driven in accordance with the refrigerant sensors.
