A refrigeration system particularly suitable for an automobile air conditioning system is disclosed. The refrigeration system uses a hydrocarbon as the working fluid. The system includes an ejector in the refrigeration cycle and a boiler which utilizes waste heat from the automobile engine. A refrigerant storage subsystem may be included in the system to provide an adequate transient response to changes in the waste heat output from the automobile engine and during the engine warm up period.
