Low pressure accumulator particularly for a CO2 operated air conditioning system

摘要

A low-pressure collector (LPC) (10) has a gaseous coolant (14), a liquid coolant in the form of a small oil-volume phase (15) and oil in the form of a large oil-volume phase (16). There are inlet (12) and outlet (13) pipes for the gaseous coolant added to the large oil-volume phase. The LPC also has a separating device (26). An Independent claim is also included for a method for operating a low-pressure collector for a carbon dioxide air-conditioning unit in a motor vehicle.
