Title:
ADAPTIVE TRANS-CRITICAL CO2 COOLING SYSTEMS FOR AEROSPACE APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2014/158280
Kind Code:
A3
Abstract:
A cooling system for an aircraft includes a first cooling circuit (702) having a first evaporator (706) and a second evaporator (708), and a second cooling circuit (704) having a third evaporator (712) and a fourth evaporator (714). One of the first and second cooling circuits (702,704) includes a first set of valves arranged to direct refrigerant through a first cooling sub-circuit, a second cooling sub-circuit, or both the first and second cooling sub-circuits based on ambient conditions. Two of the evaporators are installed on a first side of the aircraft, and the other two of the four evaporators are installed on a second side of the aircraft opposite the first side, and the first and second cooling circuits reject heat, via a heat exchanger, from their respective cooling circuit to air passing into an engine of the aircraft.
