Abstract
A device for storing refrigerant of a refrigeration circuit and a method of operating the device, in particular for an air conditioning system of a motor vehicle. The device has a housing having a volume-enclosing wall with an inlet for introducing a refrigerant-oil mixture, and an outlet, a refrigerant discharge line arranged in the interior of the housing with an inlet opening arranged above a liquid level of the refrigerant for receiving gaseous refrigerant, and a system for returning oil to a compressor having at least one through hole formed below the liquid level of the refrigerant, in particular below a filling level of the oil, in the refrigerant discharge line. In addition, at least one through hole formed in the refrigerant discharge line is formed with an adjustable through-flow cross section, which can be varied by means of a closing apparatus.
