    摘要： An air-conditioning apparatus (100, 200, 300) uses R32, a refrigerant mixture containing R32 and HFO1234yf and in which the R32 has a mass percentage of 40 % or higher, or a refrigerant mixture containing R32 and HFO1234ze and in which the R32 has a mass percentage of 15 % or higher as a heat-source refrigerant. The air-conditioning apparatus (100, 200, 300) has a low-pressure shell-structure compressor (1), a first flow switching valve (2), a heat-source-side heat exchanger (3), first flow control devices (9c to 9e), and a plurality of use-side heat exchangers (C to E) that are connected by refrigerant pipes so that a refrigeration cycle is formed. The compressor (1) has a compression chamber that is provided within a sealed container and that has an opening extending between inside and outside of the sealed container. The air-conditioning apparatus (100, 200, 300) is capable of performing a heating operation in which only heating is performed at the use-side heat exchangers (C to E), a cooling operation in which only cooling is performed at the use-side heat exchangers (C to E), and a cooling and heating mixed operation in which heating and cooling are performed in a mixed fashion at the use-side heat exchangers (C to E). The air-conditioning apparatus (100, 200, 300) includes an injection pipe (23) that connects a refrigerant circuit constituting the refrigeration cycle to the opening, and a second flow control device (24) that is provided in the injection pipe (23) and that controls an injection amount of refrigerant to be supplied to the compression chamber. The refrigerant circulating through the refrigeration cycle is injected into the compressor (1) by supplying the refrigerant into the compression chamber via the injection pipe (23) and the opening.

    摘要： To obtain an air-conditioner apparatus that can achieve energy-saving without making refrigerant circulate up to an indoor unit and whose construction work is easy.
    A refrigeration cycle is configured by connecting a compressor 10, a four-way valve 11, a heat source side heat exchanger 12, expansion valves 16a to 16e, and intermediate heat exchangers 15a and 15b by piping. A heat medium circulation circuit is configured by connecting intermediate heat exchangers 15a and 15b, pumps 21a and 21b, and use side heat exchangers 26a to 26d by piping. The outdoor unit 1 that is installed in a space such as outdoors of the building 9 and accommodates the compressor 10, the four-way valve 11, and the heat source side heat exchanger 12, and the relay unit 3 that is installed in a non-subject space 8 which is different from an indoor space 7 and is on a installation floor separated by two or more floors and accommodates the expansion valves 16a to 16e, the pump 21, and intermediate heat exchangers 15a and 15b are connected by two pipelines. The relay unit 3 and an indoor unit 2 that accommodates use side heat exchangers 26a to 26d and is installed at a position where an indoor space 7 can be air-conditioned are connected by two pipelines from outside of the wall which is a partition between inside and outside of the room.

    摘要： The present invention provides a refrigerating cycle apparatus that enables energy saving by using a refrigerant for which a high-pressure side can be operated in a gas-liquid two-phase region or a supercritical region to perform operation in which a high COP is maintained even in response to fluctuations in thermal load and temperature conditions, etc., and provides an operation control method thereof.
    In a refrigerating cycle apparatus of the present invention, a controlling means (19) sets a high-pressure pressure target value from thermal load and temperature conditions that are based on refrigerant information that has been obtained from detectors (11 through 18), and controls at least one of a rotational frequency of a compressor (1), a degree of opening of an electronic expansion valve (4), a rotational frequency of an outdoor fan (3), or a rotational frequency of an indoor fan (7) so as to match a high-pressure pressure to the high-pressure pressure target value that has been set, Here, a threshold value is set when the high-pressure pressure target value is set, and a method for setting the high-pressure pressure target value is modified depending on whether the high-pressure pressure is greater than or equal to the threshold value or less than the threshold value when the high-pressure pressure target value is decided.
