Benefits of technology

[0018]As apparent from the above description, the air conditioning system is safe from the fear of environmental pollution, has a simple structure, and does not require additional devices to reduce costs.

Problems solved by technology

However, due to a fear of oil exhaustion and environmental pollution, many efforts are made to develop a hybrid automobile or an electric automobile in various countries around the world.
This refrigerant incurs environmental issues such as disruption of an ozone layer, and requires many additional devices such as a compressor, a condenser, a refrigerant pipe, a heater hose, and so on.

Embodiment Construction

[0032]Reference will now be made in greater detail to an air conditioning system according to exemplary embodiments of the present invention with reference to the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.

[0033]Referring to FIGS. 2 and 3, an air conditioning system according to the first embodiment has an air-cooled structure in which a permanent magnet 20 is installed on one side of each rotary magnetic disc 10, each magnetic disc 10 absorbs or radiates heat according to a rotating angle thereof, and this heat heats or cools air introduced from the outside by means of heat exchangers 30 and 40.

[0034]The magnetic discs 10 are disposed in parallel along a rotary shaft 11, has the shape of an annular ring, the central portion of which is open. The central portion of each magnetic disc 10 is provided with a crisscross frame such that the magnetic discs 10 can share th...

Abstract

An air conditioning system includes at least a magnetic disc disposed in parallel along a rotary shaft thereof, permanent magnets installed within rotational radii of the respective magnetic discs, and applying magnetic fields to the magnetic disc rotating within a predetermined section, a heat exchanger for heating installed on a side of the permanent magnets, and having at least a heat radiation fin, and a heat exchanger for cooling installed on a side opposite the permanent magnets, and having at least a heat absorption fin. The air conditioning system has a simple structure, is safe from the fear of environmental pollution, and is suitable for a next-generation air conditioning system to be applied to a hybrid or electric automobile because it does not use engine heat or a refrigerant

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Korean Application No. 10-2008-0056262, filed on Jun. 16, 2008, the entire contents of which is incorporated herein by this reference for all purposes.BACKGROUND OF THE INVENTION[0002](1) Field of the Invention[0003]The present invention relates, in general to an air conditioning system and, more particularly, to an air conditioning system for a motor vehicle using a magnetocaloric effect,[0004](2) Description of the Related Art[0005]A magnetocaloric effect refers to a phenomenon that the temperature of a ferromagnetic material is increased when a strong magnetic field is applied to the ferromagnetic material on the outside, while the temperature of the ferromagnetic material is decreased when the magnetic field is eliminated.[0006]This magnetocaloric effect results from an entropy conservation law. As illustrated in FIG. 1, when a ferromagnetic material 1 is magnetized by a magnetic field generated fro...
