    • The present invention relates an air-conditioning apparatus for a car, and more particularly, to an air-conditioning apparatus for a car in which a bypass path and a regenerating path are formed in a lower portion of an air-conditioning case, such that the bypass path is in communication with a dehumidification portion of a dehumidification rotor so as to bypass a cold/hot air path, and the regenerating path supplies the air passing through the bypass path to a regenerating portion of the dehumidification rotor, and in which one area of a heater is arranged in the bypass path and the other area of the heater is arranged in a hot air path such that the dehumidified air passing through the dehumidification portion of the dehumidification rotor and then through the bypass path is heated by the heater and supplied to the regenerating portion of the dehumidification rotor so as to regenerate the dehumidification rotor. Thus, the heater divided into two areas can be used without a separate heat source in regenerating the dehumidification rotor, thereby reducing the number of components and thus the size of the apparatus. In addition, as the dehumidified air is heated in order to be used in regenerating the dehumidification rotor, a greater amount of moisture (humidity) can be removed by the dehumidification rotor, to thereby improve regeneration efficiency. In a heating mode, the heated air passing through the bypass path is blown into the hot air path through a door installed at a communication chamber, to thereby increase heating performance and airflow volume.
    • 本发明涉及一种用于汽车的空调装置,并且更具体地涉及一种用于汽车的空调装置,其中在空调壳体的下部形成有旁通路径和再生路径, 旁路通路与除湿转子的除湿部分连通以绕过冷/热空气通路,并且再生通路将经过旁路通路的空气供应到除湿转子的再生部分,并且其中一个 加热器的区域布置在旁路中,并且加热器的另一区域布置在热空气路径中,使得通过除湿转子的除湿部分然后通过旁路的除湿空气被加热器加热并且 供应到除湿转子的再生部分以再生除湿转子。 因此,可以使用分成两个区域的加热器而不需要单独的热源来再生除湿转子,从而减少了部件的数量并因此减小了装置的尺寸。 另外,由于除湿空气被加热以用于再生除湿转子,所以除湿转子能够除去更多的水分(湿度),从而提高再生效率。 在加热模式下,通过旁通路径的加热空气通过安装在连通室处的门被吹入热空气路径,由此增加加热性能和风量。

    • The present invention relates to a catalyst for selective oxidative desulfurization having a prolonged lifetime, and a preparation method thereof. More specifically, the present invention relates to a catalyst for selective oxidative desulfurization, and a preparation method thereof, wherein a catalyst for selective oxidative desulfurization in which the surface of a silica support is modified to be hydrophobic through silylation using an organic silane compound is further provided to a catalyst for selective oxidative desulfurization in which a predetermined amount of transition metals are supported in a silica support, thereby maximizing selective oxidative desulfurization performance to petroleum hydrocarbons having a high sulfur compound content and preventing sulfone compounds, by-products of selective oxidative desulfurization, from being deposited on the support of the catalyst to extend the lifetime of the catalyst to the maximum. In addition, the present invention relates to a method for preparing the catalyst for selective oxidative desulfurization, comprising: the first step of injecting in an organic solvent a transition metal precursor and a chelating agent for reaction thereof; the second step of injecting a support to an aqueous solution for mixture thereof; the third step of mixing and stirring the solutions prepared at the first and second steps; and the fourth step of drying and sintering the solution prepared at the third step. The catalyst prepared by the preparation method maintains a high catalytic activity and has an increased lifetime by preventing the formation and aggregation of large active metals showing a low reactivity in case of supporting an active metal component.
