Abstract

The invention relates to an air-conditioning system (4) comprising a coolant compressor having a low-pressure inlet (11) and a high-pressure outlet (12), and a variable flow resistance arranged in a main mass flow from the high-pressure outlet of the coolant compressor to a consumer. The invention is characterised in that a mass flow regulating device in the main mass flow has a variable flow resistance that can be adjusted by means of a control device (32).
