摘要： PROBLEM TO BE SOLVED: To improve heat exchange efficiency of a condenser by sufficiently securing wind velocity of outside air for performing a heat exchange with the condenser installed at the bottom part of the refrigerator. SOLUTION: The condenser 6 is installed so that a suction surface 6b of the condenser may be directed to the bottom surface of a main body of the refrigerator and a blow-off surface 6c of the condenser may be communicated with a machine chamber 4. By a cooling fan 2 provided in the machine chamber 4, outside air is sucked from the surrounding of the bottom surface of the main body of the refrigerator, and the condenser 6 and a compressor 1 are cooled in this order. By separating a portion from the gas blow-off surface 6c of the condenser up to an entrance 11 of the machine chamber 4 from the surrounding of the bottom surface of the main body of the refrigerator, outside air sucked from a space between the main body of the refrigerator and a floor surface is sucked from the suction surface 6b of the condenser.

摘要： PROBLEM TO BE SOLVED: To eliminate the problems of the conventional art of gurgling sound of refrigerant becomes loud, in a second flow-control valve in a dehumidification operation, and that a room-reheating dehumidification operation having a reversed flow cannot be carried out, because the flow control can be effected only in one-way flow, and further that the temperature is controlled within a very narrow range, because the throttle rate in the conventional flow control device is fixed. SOLUTION: A valve element is placed in a valve body, to which a first duct and a second duct are connected. The valve element has a restriction part, constituted of a porous permeable material and a small hole and is rotatable in the valve body. Switching operation is performed, by rotating the valve element for communication of the first conduit with a second conduit via the restriction part, and communication of the first conduit with the second conduit without having to go through the restriction part.

摘要： PROBLEM TO BE SOLVED: To provide a heat-exchanger for an air conditioner wherein the distribution performance of the heat-exchanging fluid is improved, thereby the heat- exchanging efficiency is improved, and the structure is simplified for easy mass- production. SOLUTION: A heat-exchanger comprises a plurality of heat-transfer pipes 6 which are in contact with a fin to form a heat-transfer surface and which transfers heat through a heat-exchanging fluid, a header 1 to which heat-transfer pipes 6 are connected and which has a space part for distributing the heat- exchanging fluid to the heat-transfer pipes 6, and an inlet pipe 5 which is connected to the space part of the header 1 and through which the heat-exchanging fluid flows into the space part. The header 1 has an upper part space chamber 2 and a lower part space chamber 3 comprising a plurality of space parts. The upper part space chamber 2 communicates with each of lower part space chambers 3 through narrow inlet channels 4. The inlet pipe 5 is connected to one end of the upper part space chamber 2 parallel to its longitudinal direction. The heat-transfer pipes 6 are connected to the lower part space chambers 3 perpendicularly to the inlet pipe 5.

摘要： PROBLEM TO BE SOLVED: To provide a good heat-exchanging efficiency with a simple configuration, which is easy to manufacture. SOLUTION: A heat-exchanger 3 wherein heat-transfer pipes 1 where multiple small-diameter pipes are arranged parallel and heat-exchanging fluid flows and fins 2 provided on the outside surface of the heat-transfer pipes 1 constitute a heat-transfer surface is provided, a flow-in side member 4 is disposed below the heat-exchanger 3, and a distribution header 12 wherein multiple heat-transfer pipes 1 are opened on upper side while a plurality of flow-in pipes 13 communicating with respective flow-inside member 4 are opened on lower side is provided. So, the flow-in speed of the heat-exchanging fluid which flows in the distribution header 12 from the flow-in side member 4 through the flow-in pipes 13 drops for stabilized liquid-level of the heat-exchanging fluid in the distribution header 12. Thus, the heat-exchanging fluid evenly flows in the heat-transfer pipes 1, resulting in even heat-exchanging amount on the entire surface of the heat-exchanger 3, for improved heat-exchanging efficiency.
