- (1) Field of the Invention
- 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,
- (2) Description of the Related Art
- 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.
- 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 from an externalmagnetic object 2, the ferromagnetic material is subjected to spin alignment reduction in magnetic entropy, increase in atomic lattice entropy (increase in vibration of an atomic lattice) according to a total entropy conservation law, and generation of heat. In contrast, when the magnetic field applied to the ferromagnetic material 1 is eliminated, the ferromagnetic material is subjected to reduction in the atomic lattice entropy, and thus the temperature of the ferromagnetic material is decreased. - Meanwhile, in the case of a current air conditioning system for a motor vehicle, the heat from an engine is used for heating an interior of the motor vehicle. 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. Thus, there is a practical need to displace the conventional heating system of the motor vehicle using the engine heat with another system. Further, in order to cool the interior of the motor vehicle, an ammonia-based gas called R-134a is mainly used. 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. As such, it is absolutely need to develop a so-called magnetic air conditioning system using the magnetocaloric effect from the viewpoint of reduction in cost and weight and environmental conservation.

- Referring to
FIGS. 2 and 3 , an air conditioning system according to the first embodiment has an air-cooled structure in which apermanent magnet 20 is installed on one side of each rotarymagnetic disc 10, eachmagnetic 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 ofheat exchangers - The
magnetic discs 10 are disposed in parallel along arotary shaft 11, has the shape of an annular ring, the central portion of which is open. The central portion of eachmagnetic disc 10 is provided with a crisscross frame such that themagnetic discs 10 can share therotary shaft 11 with each other. Thismagnetic disc 10 is made of a ferromagnetic material showing a strong magnetocaloric effect at an approximately room temperature. One example of the ferromagnetic material includes gadolinium, which is a rare-earth metal having high magnetic susceptibility, or a GdSiGe based mixture. - Each
permanent magnet 20 is installed within a rotational radius of eachmagnetic disc 10, and thus applies a magnetic field to eachmagnetic disc 10 rotating within a predetermined section. Eachpermanent magnet 20 is provided with a receiving slot opposite sides of which serves as N and S poles of eachpermanent magnet 20. Each rotarymagnetic disc 10, which is located in the receiving slot of eachpermanent magnet 20, intersects the magnetic field of eachpermanent magnet 20 at a right angle. Preferably, the magnitude of the magnetic field applied to eachmagnetic disc 10 by eachpermanent magnet 20 must be more than 2 tesla. Alternatively, a superconductive magnet or an electromagnet may be naturally used instead of thepermanent magnet 20. - The heat exchangers are made up of the
heat exchanger 30 for heating and theheat exchanger 40 for cooling. Theheat exchanger 30 for heating is installed on the side of thepermanent magnets 20, and includes at least aheat radiation fin 31.

magnetic disc 200, an inner wall of each hollowmagnetic disc 200 is provided with acasing 210, which prevents contact with water and has good heat transferability. Thecasing 210 is provided therein with anadiabatic partition 220. A vertical part of theadiabatic partition 220 partitions an interior of thecasing 210 into two spaces, one of which is located on the side of a permanent magnet and the other on the side opposite the permanent magnet. A horizontal part of theadiabatic partition 220 increases a heat transfer contact area between a fluid flowing in thecasing 210. - Meanwhile, the
magnetic disc 200 and itscasing 210 are rotated together around therotary shaft 201, but theadiabatic partition 220 is not rotated together, namely is fixed. Part of the rotarymagnetic disc 200 which is located on the side of thepermanent magnet 230 always generates heat, and the opposite part always absorbs heat. Thus, in the case in which theadiabatic partition 220 is fixed despite the rotation of themagnetic disc 200, water is allowed to flow only to the permanent magnet (i.e. heating channel) inside the magnetic disc during heating operation, and to flow only the opposite side (i.e. cooling channel) during cooling operation. Of course, because themagnetic disc 200 is rotated relative to theadiabatic partition 220, the water may be infiltrated from the heating channel to the cooling channel or vice versa through a gap between theadiabatic partition 220 and themagnetic disc 200, more particularly between theadiabatic partition 220 and thecasing 210. - As described above, the magnetic flux density is relatively high in the proximity of the N pole or the S pole, whereas it is somewhat low between the N pole and the S pole. Thus, as illustrated in
FIG. 7 , if therotary shaft 201 of themagnetic discs 200 is adapted to be able to move in an axial direction thereof, and then to adjust an amount of intersecting magnetic flux of themagnetic discs 200, the temperature of the air conditioning system can be adjusted. In another aspect the air conditioning system of various exemplary embodiments may have a structure in which at least one magnetic object pair (not shown) is installed on the upper and lower circumference of themagnetic disc 200 corresponding to thepermanent magnet 230. Themagnetic disc 200 can be rotated around therotary shaft 201 in a predetermined angle. Since an area where the magnetic object pair faces thepermanent magnet 230 can be adjusted by rotating themagnetic disc 200 around therotary shaft 201 at the predetermined angle, a desired air conditioning temperature can be adjusted. - In this manner, the hot water having passed through the heating channel in the
magnetic disc 200 radiates heat at the heat exchanger for heating, and then flows into a pump, while the cold water having passed through the cooling channel absorbs heat at the heat exchanger for cooling, and then flows into the pump. The pump circulates the water along each channel again. - Unlike the exemplary embodiments described above, the ferromagnetic material of the magnetic disc may be configured to reciprocate with respect to the permanent magnet.
- As illustrated in
FIG. 8 , the air conditioning system of various embodiments may have a structure in which at least onemagnetic object pair 110 is installed on the outer circumference of amovable cylinder 100, i.e., a magnetic disc, configured to reciprocate in an axial direction thereof, and in which at least onepermanent magnet pair 120 is installed outside themagnetic object pair 10 corresponding to themagnetic object pair 110. Themagnetic object pair 110 is installed on the outer circumference of themovable cylinder 100 in a diagonal direction, and thepermanent magnet pair 120 is spaced apart from themagnetic object pair 110, and applies a magnetic field to the otherpermanent magnet pair 120 through a portion of themagnetic object pair 110 which reciprocates along the axial direction of themovable cylinder 100 as themovable cylinder 100 moves along its axial direction which changes the magnetic flux density. - Meanwhile, as illustrated in
FIG. 9 , themovable cylinder 100 can be rotated around acentral shaft 101 in a predetermined angle. Thus, an area where themagnetic object pair 110 faces thepermanent magnet pair 120 can be adjusted by rotating themovable cylinder 100 around thecentral shaft 101 at a predetermined angle. Thereby, a desired air conditioning temperature can be adjusted. As described above, the air conditioning temperature is controlled through adjustment of an amount at which themagnetic object pair 10 intersects magnetic flux. - The heat exchange and circulation of the air conditioning system of various embodiments can be varied on the basis of the aforementioned embodiments and any well-known technology.
- Although exemplary embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
