Title (EN) ADAPTIVE TRANS-CRITICAL CO2 COOLING SYSTEMS FOR AEROSPACE APPLICATIONS
(FR) SYSTÈMES DE REFROIDISSEMENT DE CO2 TRANSCRITIQUES ADAPTATIFS POUR APPLICATIONS AÉROSPATIALES
Abstract:
(EN) 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.
(FR) L'invention concerne un système de refroidissement destiné à un avion qui comprend un premier circuit de refroidissement ayant un premier évaporateur et un deuxième évaporateur, ainsi qu'un second circuit de refroidissement ayant un troisième évaporateur et un quatrième évaporateur. L'un des premier et second circuits de refroidissement comprend un premier ensemble de soupapes agencées pour orienter le fluide frigorigène à travers un premier sous-circuit de refroidissement, un second sous-circuit de refroidissement ou à la fois les premier et second sous-circuits de refroidissement sur la base des conditions ambiantes. Deux des évaporateurs sont installés sur un premier côté de l'avion et les deux autres des quatre évaporateurs sont installés sur un second côté de l'avion opposé au premier côté; et les premier et second circuits de refroidissement rejettent la chaleur, via un échangeur de chaleur, à partir de leur circuit de refroidissement respectif dans l'air passant dans un moteur de l'avion.
