Description

Air conditioning device for vehicle {AIR CONDITIONING DEVICE FOR VEHICLES}

The present invention relates to a cooling and heating device for a vehicle, and more particularly, it is possible to cool and heat air through one device, supply cooled air or heated air to the passenger side by the operation of the opening and closing means, and discharge the rest. The present invention relates to a cooling and heating device for a vehicle that can increase the temperature comfort of passengers while having a simple configuration and is easy to install.

A vehicle air conditioner is an interior product of a vehicle that is installed for the purpose of ensuring the driver's front and rear view by cooling or heating the interior of the vehicle in summer or winter, or removing frost that may be trapped on the windshield during rain or winter. In general, such an air conditioner is equipped with a heating system and a cooling system at the same time, and heats or cools the air by selectively introducing outside or inside air, and then blows the air into the interior of the vehicle to cool, heat or ventilate the interior of the vehicle.

1 is a schematic diagram showing an example of a conventional vehicle air conditioner, in which the conventional vehicle air conditioner is an air conditioner case in which vents 11, 12, and 13 whose opening degree is adjusted by each door 11d, 12d, 13d are installed ( 10) and; A blower 14 connected to the 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; It is formed to include a temp door 15 for adjusting the opening degree of the cold air passage and the warm air passage of the air conditioning case 10. In the conventional vehicle air conditioner configured as described above, when the cooling cycle is operated, the temp door 15 opens the cold air passage and closes the hot air passage. Therefore, the air blown by the blower 14 passes through the evaporator E and exchanges heat with the refrigerant flowing inside the evaporator E to be converted into cold air, and then flows toward the cold air passage and opens the vent 11 , 12, 13), thereby cooling the interior of the vehicle. In addition, when the heating cycle is activated, the temp door 15 closes the cold air passage and opens the warm air passage, so that the air blown through the heater core H passes through the heater core H through the warm air passage. The interior of the vehicle is heated by heat exchange with the coolant flowing inside the core (H) to change to warmth and discharged to the interior of the vehicle through the opened vents (11, 12, 13).

On the other hand, the evaporator (E) is provided inside the air conditioning case 10, as described above, the condenser (2) is located in front of the vehicle to cool the refrigerant using the running wind, the compressor (1) Must be located inside the engine compartment as it is driven by the engine drive belt. Accordingly, there is a problem that the connection of the pipe 5 is complex.

On the other hand, a vehicle such as a truck has been proposed a non-autonomous air conditioner for a vehicle operated by a power source of a vehicle battery so that cooling can be performed even in a state in which the engine is not operated, and this is shown in FIGS. 3 and 4. 3 and 4 are perspective views and schematic diagrams showing a vehicle-free air conditioner, and first and second compressors 10a and 10b operated by a power supply of the vehicle battery shown in FIGS. 3 and 4, and First and second condensing units each in communication with the first and second compressors (10a, 10b) and each having a condenser inlet 21 through which the refrigerant flows in and a condenser outlet 22 to be discharged after heat exchange with the outside air The first and second capillary tubes 30a and 30b communicated with the vortex condenser 20 composed of (20a, 20b) and the condenser outlet 22 formed in the first and second condensing portions 20a and 20b, respectively. ) And the first and second capillaries 30a and 30b, respectively, and the evaporator inlet 41 through which the refrigerant is introduced and the introduced refrigerant exchange heat with the bettor, and the first and second compressors 10a and 10b ) And each evaporator outlet 42 is formed to be discharged to each of the first and second evaporators 40a and 40b.

However, a conventional vehicle air conditioner uses engine coolant for heating, and the vehicle silent air conditioner needs to install a separate heater to perform heating while the engine is not operated.

Accordingly, there is a demand for a device that can perform cooling and heating at the same time, can be miniaturized, and is easy to mount on a vehicle. In particular, cooling and heating are appropriate even in a form in which the engine is stopped or the engine is not used. There is a need for a device that can perform efficiently.
