Description

Vehicle air conditioning system {AIR CONDITIONER FOR VEHICLE}

The present invention relates to an air conditioning system for a vehicle, and more specifically, the interior is divided into a first area and a second area by assembling the first to third modules, and each is equipped with a first heat exchanger and a second heat exchanger. It relates to an air conditioning device for a vehicle that can be miniaturized and can easily perform cooling, heating, and dehumidifying air conditioning.

A typical vehicle air conditioning system includes a compressor that compresses and delivers refrigerant, a condenser that condenses the high-pressure refrigerant discharged from the compressor, an expansion valve that throttles the liquefied refrigerant condensed in the condenser, and the expansion valve. The condensed low-pressure liquid refrigerant is evaporated by heat exchange with the air blowing into the vehicle interior, and an evaporator that cools the air discharged into the interior by absorbing heat due to the latent heat of evaporation of the refrigerant is connected to the refrigerant pipe.

The evaporator is installed inside the air conditioning case installed inside the vehicle and plays a cooling role. That is, the air blown by the blower passes through the evaporator and is cooled by the latent heat of evaporation of the liquid refrigerant circulating within the evaporator. This is achieved by being discharged into the vehicle interior.

Additionally, the interior of the vehicle is heated using a heater core installed inside the air conditioning case through which engine coolant circulates, or an electric heater installed inside the air conditioning case.

Meanwhile, the condenser is installed on the front side of the vehicle and dissipates heat while exchanging heat with the 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 warm air passage 12 are installed inside one air conditioning case 10. ) is formed to be partitioned, an evaporator 4 for cooling is installed in the cold air passage 11, and a condenser 2 for heating is installed in the warm air passage 12. At this time, an air discharge portion 15 that supplies air into the vehicle interior and an air discharge port 16 that discharges air outside the vehicle interior are formed on the outlet side of the air conditioning case 10. In addition, individually operating blowers 20 are installed at each inlet side of the cold air passage 11 and the hot air passage 12.

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

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

However, the prior art requires space for air to flow into the cold air passage 11 and the warm air passage 12, respectively, and for dehumidification, the air passing through the cold air passage 11 flows again through the warm air passage 12. There is a problem that the overall size has to be increased because the configuration of the flow path and door is complicated.

In addition, there is an increasing demand to reduce noise to improve passenger comfort.
