摘要： In the case of a heating operation in which a use side heat exchanger functions as a condenser when the outside air has a predetermined low temperature, a low-outside-air-temperature heating operation start mode is executed in which, while a refrigerant, as discharged from a compressor, flows into the use side heat exchanger, the refrigerant, upon flowing into the injection pipe, merges with a part of the refrigerant discharged from the compressor, which has traveled through the connecting pipe and has transferred heat in the heat source side heat exchanger, and a merged refrigerant is supplied to the injection port of the compressor, and thereafter a low-outside-air-temperature heating operation mode is executed in which the refrigerant, as discharged from the compressor, is supplied to the injection port of the compressor via the injection pipe while flowing into the use side heat exchanger.

摘要： In an air-conditioning apparatus, a heat source side heat exchanger 12, intermediate heat exchangers 15a and 15b, and use side heat exchangers 26a to 26d are separately formed and adapted to be disposed at separate locations, respectively. There are provided a defrosting operation function to melt frost attached around the heat source side heat exchanger 12, and a heating function during defrosting operation that drives a pump 21a to circulate a heat medium and supply heating energy to the use side heat exchangers 26a to 26d in need of heating to perform heating operation. The defrosting operation function can be executed by switching a four-way valve 11 to cooling side to introduce a high-temperature high-pressure refrigerant flowed out of the compressor 10 into the heat source side heat exchanger 12.

摘要： A refrigeration cycle apparatus includes a refrigerant circuit of a refrigeration cycle through which a refrigerant that transits in a supercritical state is allowed to flow, and a flow dividing device 14 that divides the flow of a high-pressure liquid refrigerant in a subcritical state into two or more parts. The flow dividing device 14 is configured such that the device is oriented substantially in the horizontal direction or substantially upward in the vertical direction relative to the direction of flow of the refrigerant in a liquid state. With such a configuration, the flow of refrigerating machine oil is equally divided, thus offering high energy saving while keeping heat-medium conveyance power at a low level without reducing the heat exchanging performance.
