    • PROBLEM TO BE SOLVED: To reduce noise by a turbo fan by protruding a rib for partitioning between four corners of a partition plate disposed parallely to a rear surface of a heat exchange part with a gap and a region inside the corners on a front surface side of the partition plate. SOLUTION: An internal chassis 20 is provided in a substantially rectangular casing 1 mounted on a wall surface in a room on a rear surface side thereof. A region of the internal chassis 20 inside a support part forms a partition plate 22 disposed parallely with a gap 30 to a rear surface of a heat exchanger 3. There are protruded four ribs 24 on the front surface side of the partition plate 22 for partitioning a portion between four corners of the partition plate 22 and a region inside the former. Each rib 24 is formed into a circular arc shape separated away by a predetermined distance in a radial direction from a circular hole in a bell-mouthed opening 21 in a plate surface of the partition plate 22, and is protruded frontally by a predetermined height with a plate surface of the partition plate 22 taken as a reference. In an assembled state a front end of each rib 24 makes contact with a rear surface of the heat exchanger 3, and secures the gap 30 between the rear surface of the heat exchanger 3 and the partition plate 22.

    • PROBLEM TO BE SOLVED: To provide a heat-exchanger capable of dividing-and-distributing refrigerant at a uniform gas-liquid ratio. SOLUTION: A heater 12 comprises a cylinder pipe and is disposed horizontally. Refrigerant pipe 13 are vertically extended below the header 12 in parallel and mounted with the upper end thereof inserted in the header 12. An amount of insertion of each refrigerant pipe 13 in the heater 12 is increased on the inlet side of the refrigerant of the header 12 and gradually decreased toward a spot situated deep. A plurality of liquid bleed holes are formed in the lowermost part of a pipe wall (an insertion pipe wall) inserted in the header 12 of the refrigerant pipe 13 having the insertion amount exceeding a given value. This constitution further increases resistance of the insertion pipe wall against a refrigerant in the refrigerant pipe 13 positioned on the refrigerant inlet side of the header 12, increases an amount of a separated liquid refrigerant, and a gas refrigerant precedently flows in to prevent the increases of a value of a gas refrigerant amount/a liquid refrigerant amount.

    • PROBLEM TO BE SOLVED: To prevent noise and improve heat exchange efficiency. SOLUTION: The indoor machine is provided with a heat exchanger 1 where a plurality of flat heat transfer pipes are disposed, a bell-mouth 2 disposed on a rear surface side of the heat exchanger 1, and a turbo fan 3 disposed on a rear surface side of the bell-mouth 2 for blowing out air sucked from a front surface side radially outwardly with respect to a shaft. Bent parts 4, 4 bent toward the side of the turbo fan 3 are provided on a opposite sides of the flat heat transfer pipe of the heat exchanger 1 in the direction of disposition of the same. Since a longitudinal direction of a cross section of the flat heat transfer pipe on the opposite sides 4, 4 of the heat exchange 1 is directed to a central suction inlet side of the bellmouth 3, a stream of air along the bent parts 4, 4 of the heat exchanger 1 is made smooth, and hence disturbance of the air stream is restricted. Further, there is reduce variations in air velocity distribution passing through the heat exchanger 31.

    • PROBLEM TO BE SOLVED: To provide an oxygen enrichment apparatus capable of eliminating the transmission of bubbling sound to a living room and preventing unintentional dilution of oxygen concentration of oxygen-enriched air. SOLUTION: The oxygen enrichment apparatus 15 comprises an oxygen enrichment membrane module 61, a vacuum pump 65, an air supply fan 54, and an oxygen-enriched air discharge path 67. The oxygen enrichment membrane module 61 comprises a casing 62 and an oxygen enrichment membrane 63. The oxygen enrichment membrane 63 is installed in the casing 62 in a manner that a space in the casing 62 is divided into a primary side space S1 and a secondary side space S2. The vacuum pump 65 is installed for producing first oxygen-enriched air in the secondary side space S2 by reducing the pressure of the secondary side space S2 so as to pass the air supplied to the primary side space S1 through the oxygen enrichment membrane 63 toward the secondary side space S2. The air supply fan 54 is installed to supply the first oxygen-enriched air to an object space to be enriched with oxygen. The oxygen-enriched air discharge path 67 is installed for discharging the firsts oxygen-enriched air to a installation space SP of the air supply fan from the vacuum pump 65.
