摘要

A vapour compression cooling circuit arrangement, comprises a compressor (110) for sucking and compressing a coolant, an outer heat exchanger (130), an ejector pump coupled to the outer heat exchanger, and an ejector pump nozzle which is adjustable. A primary inner heat exchanger enables heat to be exchanged between the coolant and air. A side flow path runs from a branch between the outer heat exchanger and the nozzle, and is connected to the coolant suction opening. A secondary inner heat exchanger is located in the side flow path.
