Abstract (en)

[origin: WO2013164036A1] A refrigeration circuit (1a, 1b, 1c, 1d, 1e) comprises a compressor (2), a condenser (14a, 14b), an expansion device (8), an evaporator (10), a heat rejecting heat exchanger (4), and a gas-liquid-separator (6), which is configured to separate the refrigerant leaving the heat rejecting heat exchanger (4) into a gaseous phase refrigerant portion and liquid phase refrigerant portion. The gas-liquid-separator (6) has a liquid phase output line (6b) with a liquid refrigerant control device (16). The refrigeration circuit (1a, 1 b, 1c, 1d, 1e) further comprises a liquid meter (18), which is configured to measure the level of liquid refrigerant within the gas-liquid-separator (6), and a liquid level control device (20) coupled to the liquid meter (18) and to the liquid refrigerant control device (16). The liquid level control device (20) is configured to drive the liquid refrigerant control device (16) based on a signal provided by the liquid meter (18).
