A humidifier (,) includes upper and lower water tanks (,) and (,) supported by a support frame (,). In a space between the upper and lower water tank, a plurality of hollow yarn bodies (,) are arranged in communication with upper and lower water tanks. The hollow yarn body is constructed of a parens yarn (,) of the hollow and a thin metal wire (,) connected to the power source thereof and wound around the hollow yarn body.

Humidifier and hollow yarn body to be used therefor

Air conditioning apparatus

There is provided a water feed device for humidification, comprising: an outflow reservoir that is disposed above a humidifier for feeding water into the humidifier by way of a permeation and that is provided with an overflow dam for maintaining a level of the water in the outflow reservoir substantially constant; an inflow reservoir that is disposed upwards of the outflow reservoir and that is provided with a flow inlet; a partition plate that is disposed between the inflow reservoir and the outflow reservoir; and a plurality of drip feed members which are provided in the partition plate for allowing the water in the inflow reservoir to drop by gravity in a form of droplets into the outflow reservoir. There is also provided an air conditioning apparatus in which a cooling dehumidifier unit, a heater unit, a humidifier unit and an air blower unit are successively arranged within an air duct which is provided in a housing in a horizontal direction; the air duct is provided with an outlet side that is connected to an outlet duct which is opening towards an area to be air conditioned; downwards of respective portions of the cooling dehumidifier unit and the humidifier unit in the air duct there are provided a pair of water proof trays, respectively, which are communicated via respective hoses with the cooling dehumidifier unit and the humidifier unit, respectively, and which are provided with a drainage means that is opening to an outside of the housing; and downwards of the water proof trays and downwards of the air duct there is provided a further water proof tray having a drainage means that is opening to an outside of the housing.

A porous hollow fiber membrane is dipped into either a high concentration alkali solution or a high concentration solution of chromic acid and sulfuric acid, etched and then dipped into a palladium ion solution. The membrane is then dipped into a solution containing reducing and complexing agents as well as metallic ions, and subjected to an electroless treatment. In this way, a porous hollow fiber membrane, to which a metallic layer is chemically bonded, can be obtained. The porous hollow fiber membrane is provided in which the bond strength between the membrane and the metallic layer and the amount of metal to be coated are increased. Because of a large amount of metal, it is possible to render the membrane sufficiently electrically conductive.
