Abstract (en)
A cooling system (1200, 1300, 1400) includes a main refrigerant circuit (1202) that includes a compressor (1206), a heat rejection heat exchanger (1210, 1310, 1418), one of an expander (1302, 1402) and an expansion device (1212), at least one evaporator (1214, 1306, 1404, 1406) coupled to a thermal load, and a suction accumulator (1216). A charge management circuit (1204) includes a charge management receiver (1228) configured in parallel with the compressor (1206) and the heat rejection heat exchanger (1201, 1310, 1418). A controller (1218) is configured to accumulate and discharge reserve refrigerant to and from the charge management receiver (1228) to provide flexibility in system operation as refrigerant in the main refrigerant circuit (1202) operates in sub-critical, trans-critical, and super-critical modes of operation.
