1. A vapor cycle refrigeration system for an aircraft, the system comprising:
a compressor,
a condenser unit with a condenser radiator, a condenser fan and a condenser air duct configured to direct a stream of air generated by the condenser fan through the condenser radiator,
an expansion device,
an evaporator unit with an evaporator radiator, an evaporator fan and an evaporator air duct configured to direct a stream of air generated by the evaporator fan through the evaporator radiator, and
a piping system connecting the compressor, the condenser radiator, the expansion device and the evaporator radiator in a closed circuit for a refrigerant,
wherein each of the compressor, the condenser radiator, the condenser fan, the expansion device, the evaporator radiator, the evaporator fan and the piping system is fully supported directly or indirectly by at least one of the condenser air duct and the evaporator air duct in such a manner that the system is self-supporting.
