20100281649 | INDOOR UNIT OF AIR CONDITIONER - An indoor unit of an air conditioner having an air filter provided on a suction side of an indoor fan has a construction in which dust removed from the air filter by a dust removing part can be recovered easily and reliably. The construction includes a dust removing part ( | 11-11-2010 |
20100287968 | INDOOR UNIT OF AIR CONDITIONER - Disclosed is an indoor unit having a dust storage container in which dust removed from an air filter is stored, and a dust collecting box into which the dust in the dust storage container is transferred by utilizing an effect of blown air. The dust storage container is provided with a full condition detection means for detecting a dust full condition of the dust collecting box. The full condition detection means includes an LED and a phototransistor which are opposed to each other with a storage portion interposed therebetween. After a dust transfer operation which transfers the dust from the dust storage container to the dust collecting box, an intensity of light of the LED that has passed through the storage portion is detected by the phototransistor. If the detected light intensity is equal to or less than a set value, a full condition of the dust collecting box is detected. | 11-18-2010 |
20120073786 | CEILING-MOUNTED AIR CONDITIONING UNIT - A ceiling-mounted air conditioning unit includes an indoor heat exchanger disposed on an outer peripheral side of a centrifugal blower. The indoor heat exchanger includes plural heat transfer tubes arranged in multiple stages in a vertical direction and in three rows in a flow direction of air blown out from the blower and are connected to a refrigerant inlet of the indoor heat exchanger in a case where the indoor heat exchanger functions as an evaporator of the refrigerant during cooling, plural liquid refrigerant tubes connected to the heat transfer tubes in a first row on a most upwind side, second row-side gas refrigerant tubes connected to a refrigerant outlet of the indoor heat exchanger during cooling and connected to the heat transfer tubes in a second row, and third row-side gas refrigerant tubes connected to the heat transfer tubes in a third row on a most downwind side. | 03-29-2012 |

20120288363 | CEILING-MOUNTED INDOOR UNIT FOR AIR CONDITIONING APPARATUS - A ceiling-mounted indoor unit for an air conditioning apparatus is disposed in a ceiling of an air-conditioned room. The ceiling-mounted indoor unit includes a casing having an air outlet formed along a peripheral edge portion of an undersurface of the casing, at least four horizontal blades rotatably disposed in the air outlet, and a controller. The horizontal blades have airflow-direction angles that are independently changeable in an up-and-down direction. The control unit controls the horizontal blades such that at least two first horizontal blades of the at least four horizontal blades synchronously swing while taking the same posture. The first horizontal blades are adjacent to each other, and a combination of the at least four horizontal blades forming the first horizontal blades shifts in order along the peripheral edge portion. | 11-15-2012 |
20120318487 | HEAT EXCHANGER FOR AIR CONDITIONER - A heat exchanger comprises a plurality of refrigerant tubes. In a flow divider, a part of a plurality of capillary tubes is connected to an open end portion on a side of a front tube plate, and a remainder of the plurality of the capillary tubes is connected to an open end portion on a side of a rear tube plate. The plurality of refrigerant tubes include even number refrigerant tubes constituted by an even number of heat transfer tube portions and odd number refrigerant tubes constituted by an odd number of heat transfer tube portions. | 12-20-2012 |
20130014540 | HEAT EXCHANGE DEVICE AND COMMUNICATION TUBE USED IN THE SAMEAANM Michitsuji; YoshiharuAACI Sakai-shiAACO JPAAGP Michitsuji; Yoshiharu Sakai-shi JP - A heat exchange device includes a heat exchanger having a plurality of heat transfer tubes through which a refrigerant is circulated and functioning as an evaporator, a plurality of communication tubes connected to ends of the heat transfer tubes on the refrigerant discharge side, and a header connected to ends of the plurality of communication tubes on the refrigerant discharge side, the header for joining the refrigerant discharged from the communication tubes. At least a part of the plurality of communication tubes includes a flow passage enlargement communication tube formed in such a manner that a flow passage sectional area on the side of the header is larger than a flow passage sectional area on the side of the heat transfer tubes. | 01-17-2013 |
20130327509 | HEAT EXCHANGER FOR AIR CONDITIONER - A heat exchanger has a plurality of paths as refrigerant paths, and at least one of the plurality of paths has a coexistent path, in which both of a parallel flow portion where refrigerant flows from a heat transfer tube of one of the tube rows to a heat transfer tube of a tube row which is on a downstream side of the one tube row in terms of an air flow direction, and a counter-flow portion where refrigerant flows from a heat transfer tube of one of the tube rows to a heat transfer tube of a tube row which is on an upstream side of the one tube row in terms of the air flow direction, exist in use both as a condenser and as an evaporator. | 12-12-2013 |
20140374075 | INDOOR UNIT - Of four corner covers in an indoor unit, a horizontal length of an outer surface in a second corner cover is the same as a horizontal length of an outer surface in a first corner cover, a horizontal length of an outer surface in a third corner cover and a horizontal length of an outer surface in a fourth corner cover are the same and are smaller than the horizontal length of the outer surface of the first corner cover. Opening dimensions of four air outlet ports in a horizontal direction are the same. | 12-25-2014 |
