摘要： An internal intermediate pressure type two-stage compression rotary compressor (10) is provided with an electrically driven element (14) disposed within a sealed vessel (12), and first and second rotary compression elements (32, 34) driven by the electrically driven element (14), and is structured such as to discharge CO2 refrigerant gas compressed at a first stage by the first rotary compression element (32) within the sealed vessel (12) and compress the discharged refrigerant gas having an intermediate pressure at a second stage by the second rotary compression element (34) via an accumulator (106). The rotary compression elements (32, 34) include upper and lower cylinders (38, 40), upper and lower rollers (46, 48) eccentrically rotating within the cylinder and upper and lower vanes (50, 52) brought into contact with the rollers so as to section the inner portions of the upper and lower cylinders into high pressure chambers and low pressure chambers. A ratio of volume between the upper and lower cylinders (38, 40) executing the compression operation at the first stage and the second stage is set to 1:0.65 so that an equilibrium pressure becomes equal to an intermediate pressure. Since a pressure change at a time of starting is reduced, an oil foaming is restricted and it, is possible to easily employ a withstand pressure design of a sealed vessel, it is possible to easily design a withstand pressure vessel and it is possible to reduce a weight of the pressure vessel.

摘要： A double-cylinder two-stage compression rotary compressor (10) comprising a first and a second compressors (32 , 34), driven by an electric motor (14), all accommodated in a sealed container (12). The first and the second compressor (32, 34) have respective first and second cylinders (40, 42) accommodating first and second rollers (48, 50), fitted on respective first and second eccentric cams (44, 46). The inner spaces of the first and second cylinders are partitioned by respective first and second vanes (52, 54) to form suction spaces and compression spaces. The two cylinders are separated by an intermediate partition panel (38), which has a central bore (36) for passing therethrough a shaft (16) of the motor (14). The center of the bore (36a) of the intermediate partition panel (38) facing the first roller (48) is offset away from the center-of the shaft (16) to an angular position having a central angle about the center of the shaft in the range of 90±45 degrees with reference to the first vane (52), and the center of the bore (36b) of the intermediate partition panel (38) facing the second roller (50) is offset about the center of the shaft (16) by an angle in the range of 270-360 degrees to increase the sealing areas of the rollers with the intermediate partition panel, thereby decreasing the leakage of the refrigerant gas and increasing volumetric efficiency and pressure efficiency of the compressor.

摘要： Refrigerant exiting a condenser (1) is diverted into first and second parts, with the first part passed to a first intercooler (6) via a first decompression means (3) while the second part is passed to an evaporator (8) via a second decompression means (7). The refrigerant passed to the second decompression means (7) undergoes heat exchange with the intercooler (6). The refrigerant discharged from the evaporator (8) is fed to a first stage low-pressure compression means (32). In the multi-stage compression apparatus, the refrigerant discharged-from the low-pressure compression means (32) is mixed or merged with the refrigerant exiting the intercooler (6) at a merging point (106), and then fed to a second stage high-pressure compression means (34). The displacement volume of the low-pressure compression means (32) is larger than that of the high-pressure compression means(34). Provided between the first intercooler (6) and the merging point (106) is a one-way valve (9) for permitting the flow only in the direction from the first intercooler (6) to the merging point (106). The inventive multi-stage compression refrigeration apparatus may perform refrigeration with suppressed temperature of refrigerant gas discharged from the high pressure compression means (34). The apparatus can attain its stable normal operating condition in a short time. Thus, the inventive refrigeration apparatus has an improved refrigeration efficiency.

摘要： A multi-stage compression refrigeration apparatus (10) includes a compressor having a first stage low-pressure compression means (32) and a second stage high-pressure compression means (34), a condenser (1), a first decompression means (3), an intercooler (6), a second decompression means (7), and an evaporator (8). The refrigerant discharged from the condenser (1) is diverted into first and second parts, with the first part passed to the intercooler (6) via the first decompression means (3) while the second part is passed to the evaporator (8) via the second decompressor (7). The refrigerant passed to the second decompressor (7) undergoes heat exchange with the intercooler (6). The refrigerant discharged from the evaporator (8) is fed to the low-pressure compression means (32). The refrigerant discharged from the intercooler (6) is fed to the high-pressure compression means (34) together with the refrigerant discharged from the low-pressure compression means. The apparatus further comprises a second intercooler (5) downstream of the evaporator (8) so that the second diverted part of the refrigerant may undergo heat exchange in the intercooler (5) prior to entering the evaporator. The inventive apparatus thus may perform refrigeration with an improved efficiency during an early stage of its startup.

摘要： An air conditioner includes: an outdoor fan provided in an outdoor unit; a permanent magnet synchronous motor that drives the outdoor fan; an inverter that uses a DC power source as a power source and applies a voltage to the permanent magnet synchronous motor; an inverter control means that controls the output voltage of the inverter; and a shunt resist connected between the DC power source and the inverter. If the outdoor fan is rotating due to an external force while the inverter is stopped, the inverter control means causes the inverter to operate using a brake sequence that brakes the rotation of the outdoor fan, and then causes the inverter to operate using a drive sequence that power-drives the outdoor fan.

摘要： Whereas a high masking effect can be secured in a space to which a masking sound is emitted, the degree of a discomfort a person existing in the space suffers can be reduced. In superimposition processing, a CPU 21 extracts sound signals in different intervals of a sound signal X12-n of a human voice, superimposes the extracted sound signals on each other on the time axis, and outputs a resulting superimposed sound signal X13-n. In shift and addition processing, the CPU 12 interchanges a sound signal, before a reference position, of a sound signal X16-n and a sound signal, after the reference position, of the sound signal X16-n (shift processing) and outputs a sound signal X17-n obtained by adding together a shift-processed sound signal X16′-n and the original, non-shift-processed sound signal X16-n.
