Abstract:
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.
Abstract:
Provided is a power transmission device for a water pump for cooling automobile engines, wherein power regulation between a disk and hub in the power transmission device for a water pump can be rapidly and accurately effected, and wherein wear and damage to constituent parts can be prevented. The power transmission device comprises a pulley, a magnetic flux generating means, a disk assembly, and a hub assembly. The disk assembly comprises a disk, a friction ring which makes frictional contact with the hub assembly, and a resilient ring which resiliently presses the friction ring towards the hub assembly. When the attracting magnetic flux of the magnetic flux generating means is not applied, the friction ring makes frictional contact with the hub assembly due to resilient pressing of the resilient ring, whereas, when the attracting magnetic flux is applied, the disk moves towards the pulley such that the frictional contact between the friction ring and the hub assembly is broken.
