BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling and heating apparatus for a vehicle, and more particularly, to a cooling and heating apparatus for a vehicle which can perform cooling and heating through a single apparatus and can be downsized and is easy to mount.

Background Art [0002] A vehicle air conditioner is an automobile interior product installed for the purpose of enabling a driver to secure front and rear vision by removing air from the windshield during rainy weather or winter season by cooling or heating the interior of the automobile in the summer or winter season, Such an air conditioner usually has a heating system and a cooling system at the same time so that the outside air or the inside is selectively introduced to heat or cool the air and then air is blown into the interior of the automobile to cool,

FIG. 1 is a schematic view showing an example of a conventional air conditioner for a vehicle. The conventional air conditioner for a vehicle includes an air conditioning case (not shown) provided with vents 11, 12 and 13 whose openings are controlled by respective doors 11d, 12d and 13d 10); A blowing unit 14 connected to an inlet of the air conditioning case 10 to blow outside air; An evaporator (E) and a heater core (H) provided in the air conditioning case (10); And a tempo door (15) for regulating the opening of the air passage and the warm air passage of the air conditioning case (10). In the conventional automotive air conditioner configured as described above, when the cooling cycle is activated, the tempo door 15 opens the cold air passage and closes the warm air passage. Therefore, the air blown by the blowing fan 14 passes through the evaporator E and is exchanged with the refrigerant flowing through the inside of the evaporator E to be converted into a cool air. Then, the air flows toward the cool air passage, , 12, and 13, thereby cooling the interior of the vehicle. In addition, when the heating cycle is activated, the temp door 15 closes the cool air passage and simultaneously opens the warm air passage. The air blown through the heater core H passes through the heater passage H, Exchanges heat with the cooling water flowing in the core H and is discharged to the interior of the vehicle through open vents 11, 12 and 13, thereby heating the interior of the vehicle.

In order to supply cold refrigerant to the evaporator, a compressor (1) for compressing and sending the refrigerant as shown in FIG. 2, a condenser (1) for condensing the high-pressure refrigerant sent from the compressor (1) Pressure liquid refrigerant throttled by the expansion means (3) to the air in the passenger compartment (2), heat exchanging means (3) for condensing the refrigerant condensed in the condenser (2) And an evaporator E for cooling the air discharged into the room by the endothermic effect of the latent heat of evaporation of the refrigerant by evaporating the refrigerant by connecting the refrigerant pipe 5 to the evaporator. As described above, the evaporator E is provided inside the air conditioning case 10, and the condenser 2 is located in front of the automobile to cool the refrigerant using running wind, Must be located within the engine compartment as driven by the engine drive belt. Accordingly, there is a problem that the connection of the pipe 5 becomes complicated.

On the other hand, a vehicle ignition type air conditioner which is powered by a vehicle battery so that a vehicle such as a truck can be cooled even when the engine is not operated has been proposed, which is shown in FIG. 3 and FIG. 3 and 4 are a perspective view and a schematic view of the ignition and air-conditioning apparatus for a vehicle, respectively. FIG. 3 and FIG. 4 illustrate first and second compressors 10a and 10b, The condenser inlet 21 communicating with the first and second compressors 10a and 10b to receive the refrigerant and the first and second condensers 21 and 22 having the condenser outlet 22 for discharging the refrigerant after the heat- (30a, 30b) communicating with the condenser outlet (22) formed in the first and second condensers (20a, 20b), respectively, and a second condenser The first and second compressors 10a and 10b communicate with the first and second capillaries 30a and 30b, respectively. After the refrigerant flows into the evaporator inlet 41 through which the refrigerant flows, The evaporator 40 includes a first evaporator 40a and a second evaporator 40b.

However, in the conventional automotive air conditioning system, engine cooling water is used for heating, and in the ignition and air-conditioning apparatus for a vehicle, a separate heater is required to perform heating in a state where the engine is not operated.

Accordingly, there is a demand for an apparatus that can perform cooling and heating at the same time, can be miniaturized, and is easy to mount on a vehicle. Particularly, even when the engine is stopped or the engine is not used, A device capable of performing such operations is required.
