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 cold-storage heat exchanger. The cold-storage heat exchanger includes a pair of header tanks, and tubes which are arranged in three rows with respect to the direction of the flow of air and connected at opposite sides thereof to the header tanks. A cold-storage medium is stored in the tubes that are disposed in a middle row, and refrigerant circulates through the tubes that are disposed in front and rear rows. Therefore, the cold-storage medium can effectively store cold-energy transferred from the refrigerant. When the engine of a vehicle is stopping, the cold-storage heat exchanger can discharge the cold-energy that has been stored into the passenger compartment of the vehicle, thus preventing the temperature in the passenger compartment from rapidly increasing, thereby creating pleasant air-conditioned conditions for a user, and minimizing the energy and time required to re-cool the passenger compartment.
