Air conditioning system for vehicle {AIR CONDITIONING SYSTEM FOR VEHICLE}

The present invention relates to an air conditioning system for a vehicle, and more particularly, effectively cooling and heating the entire vehicle using a first air conditioning module and a second air conditioning module that are provided on one side and the other side of the vehicle, respectively, and capable of cooling and heating by circulating a refrigerant. The present invention relates to an air conditioning system for a vehicle capable of circulating and ventilating air quickly while increasing air conditioning efficiency by enabling individual control.

A typical vehicle air conditioner system includes a compressor that compresses and delivers a refrigerant, a condenser that condenses the high-pressure refrigerant sent from the compressor, an expansion means that condenses the liquefied refrigerant by condensing in the condenser, and the expansion means. An evaporator, etc., which cools the air discharged into the room due to an endothermic action by the latent heat of evaporation of the refrigerant by heat exchange with the air blown to the interior of the vehicle by evaporating the low pressure liquid refrigerant throttled by the refrigerant pipe.

The evaporator is installed inside the air conditioning case installed in the vehicle interior to play a cooling role, that is, the air blown by the blower is cooled by the latent heat of evaporation of the liquid refrigerant circulating in the evaporator while passing through the evaporator. It is achieved by being discharged into the vehicle interior.

In addition, the interior of the vehicle may be heated using a heater core installed inside the air conditioning case and circulating engine coolant, or an electric heating type heater installed inside the air conditioning case.

On the other hand, the condenser is installed on the front side of the vehicle to heat dissipation while exchanging heat with air.

Recently, a heat pump system that performs cooling and heating using only a refrigeration cycle has been developed. As shown in FIG. 1, a cold air passage 11 and a hot air passage 12 inside one air conditioning case 10 ) Is formed to be partitioned, an evaporator 4 for cooling is installed in the cooling air passage 11, and a condenser 2 for heating is installed in the hot air passage 12. At this time, at the outlet side of the air conditioning case 10, an air outlet 15 for supplying air into the vehicle interior and an air outlet 16 for discharging air outside the vehicle interior are formed. In addition, blowers 20 that operate individually are installed at each inlet side of the cold air passage 11 and the warm air passage 12.

Therefore, in the cooling mode, the cool air cooled while passing through the evaporator 4 of the cooling air passage 11 is discharged into the vehicle interior through the air outlet 15 to be cooled, and at this time, the condenser of the hot air passage 12 ( The warm air heated while passing through 2) is discharged to the outside of the vehicle through the air outlet 16.

In the heating mode, the hot air heated while passing through the condenser 2 of the hot air passage 12 is discharged into the vehicle interior through the air discharge port 15 to be heated, and at this time, the evaporator 4 of the cold air passage 11 ), the cooled air is discharged to the outside of the vehicle through the air outlet 16.

Meanwhile, as various vehicle types are developed, the need for air conditioning in the rear seats as well as the front seats is increasing. When the air conditioning wind of the front seat air conditioner is transferred through a duct and air-conditioning the rear seats, a space to form a duct is required, but it is difficult to secure enough space inside the vehicle.In the case of cooling, heat exchange during the transfer process causes the temperature difference between the front and rear seats. There is a problem that occurs.

In addition, it has been proposed that a rear seat air conditioner is provided along with the front seat air conditioner, but when the heating of the rear seat air conditioner uses the waste heat of the cooling water, the use is limited only to vehicles with cooling water, and when there is no waste heat from the cooling water, heating There is a problem that this is not done effectively. In addition, when the heating of the rear seat air conditioner is used as an electric heater, there is a problem in that the vehicle fuel economy is deteriorated due to excessive energy consumption.
