1. A thermal management system for an aircraft including a propeller arrangement and a battery powering the propeller arrangement, the thermal management system comprising:
a refrigeration circuit including a compressor, a condenser arrangement, an expansion valve, and a chiller, the compressor being configured to route a refrigerant past the condenser arrangement and past the expansion valve to the chiller, the condenser arrangement including an air-cooled condenser exposed to ambient temperature air outside the aircraft and a liquid-cooled condenser;
a battery cooling circuit configured to route first coolant past the battery of the aircraft, the battery cooling circuit including a first tank, a first pump, and the chiller, the first pump being configured to direct the first coolant from the first tank, past the battery at which heat is absorbed by the first coolant, to the chiller at which heat is rejected from the first coolant to the refrigerant; and
a propeller arrangement cooling circuit configured to cool the propeller arrangement of the aircraft using second coolant drawn from a second tank by a second pump, the propeller arrangement cooling circuit including a radiator arrangement exposed to the ambient temperature air, the propeller arrangement cooling circuit including a condenser routing path leading past the liquid-cooled condenser of the refrigeration circuit so that any second coolant routed along the condenser routing path cools the liquid-cooled condenser.
