摘要： A refrigerant circuit (20) is provided with an intermediate pressure heat exchanger (40) and a gas/liquid separator (51). In a cooling mode, a part of refrigerant condensed in an outdoor heat exchanger (36) flows into injection piping (43). The refrigerant admitted into the injection piping (43) is pressure reduced down to an intermediate pressure during its passage through an injection expansion valve (44), evaporates in the intermediate pressure heat exchanger (40), and is supplied to an intermediate pressure port (32) of a compressor (31). In a heating mode, refrigerant condensed in an indoor heat exchanger (71) is pressure reduced down to an intermediate pressure during its passage through an indoor expansion valve (72) and then flows into the gas/liquid separator (51). And, the intermediate pressure gas refrigerant within the gas/liquid separator (51) is supplied to the intermediate pressure port (32) of the compressor (31).

摘要： A compressor (20) is provided with compression mechanisms (61, 62) to have four compression chambers (61, 62, 63, 64) in total. In the compressor (20), the first compression chamber (61) and the second compression chamber (62) differ in the phase of capacity changing cycle from each other by 180° and the third compression chamber (63) and the fourth compression chamber (64) also differ in the phase of capacity changing cycle from each other by 180°. In a cylinder nonoperating mode, refrigerant is compressed in a single stage in each of the first compression chamber (61) and the second compression chamber (62) while the refrigerant compression operation is halted in the third compression chamber (63) and the fourth compression chamber (64). In a two-stage compression mode, refrigerant compressed in a single stage in each of the first compression chamber (61) and the second compression chamber (62) is further compressed in the third compression chamber (63) and the fourth compression chamber (64).

摘要： A refrigerant circuit of an air conditioning apparatus includes a heat source unit, a utilization unit having a utilization-side heat exchanger, and liquid and gas refrigerant connection pipes interconnecting the heat source unit and the utilization unit. The heat source unit has an adjustable capacity compressor, a heat source-side heat exchanger, an expansion mechanism and an accumulator. The refrigerant circuit can perform at least cooling operation. Compressor frequency, degree of superheat, and degree of supercooling are stored in a stable state where the degree of supercooling has been made equal to or greater than a first predetermined value. After a predetermined time period, the degree of supercooling is detected while compressor frequency and degree of superheat become the stored compressor frequency and degree of superheat. The detected degree of supercooling is compared with the stored degree of supercooling to determine adequacy of the quantity of refrigerant inside the refrigerant circuit.

摘要： A refrigerant circuit of an air conditioning apparatus includes a heat source unit, a utilization unit having a utilization-side heat exchanger, an expansion mechanism, and liquid and gas refrigerant connection pipes interconnecting the heat source unit and the utilization unit. The heat source unit has an adjustable capacity compressor, a heat source-side heat exchanger, and a cooling heat source adjusting part to adjust cooling action of a cooling heat source with respect to the heat source-side heat exchanger. The refrigerant circuit can perform at least a cooling operation. A determination of the adequacy of the quantity of the refrigerant charged inside of the refrigerant circuit is made based on a first degree of supercooling corrected value derived by correcting a degree of supercooling or an operating state quantity by at least one of outside air temperature, condensation temperature, and a value obtained by numericizing cooling action.
