## Abstract

An air conditioning system for a vehicle may include a cooling module including a cooling duct, a cooling inlet formed at one side of the cooling duct, a cooling interior outlet and a cooling exterior outlet formed at an opposite side of the cooling duct, and an evaporator provided in an interior of the cooling duct, a heating module including a heating duct, a heating inlet formed at one side of the heating duct, a heating interior outlet and a heating exterior outlet formed at an opposite side of the heating duct, and a condenser provided in an interior of the heating duct, and a cooling blower and a heating blower provided in the respective interiors of the cooling duct and the heating duct.

## Claims

### Claim 1

An air conditioning system for a vehicle, comprising:
a cooling module including a cooling duct, a cooling inlet formed at one side of the cooling duct, a cooling interior outlet and a cooling exterior outlet formed at an opposite side of the cooling duct, and an evaporator provided in an interior of the cooling duct;
a heating module including a heating duct, a heating inlet formed at one side of the heating duct, a heating interior outlet and a heating exterior outlet formed at an opposite side of the heating duct, and a condenser provided in an interior of the heating duct; and
a cooling blower and a heating blower provided in the respective interiors of the cooling duct and the heating duct.

### Claim 2 (depends on 1)

The air conditioning system of claim 1, wherein the condenser provided in the interior of the heating duct and an evaporator provided in the interior of the cooling duct are connected to a refrigerant passage.

### Claim 3 (depends on 2)

The air conditioning system of claim 2, wherein a compressor and an expansion value are connected together to the refrigerant passage.

### Claim 4 (depends on 1)

The air conditioning system of claim 1, further comprising exhaust adjusting doors provided between the interior outlets and the exterior outlets of the respective cooling duct and the respective heating duct, for adjusting an amount of air discharged to an outside.

### Claim 5 (depends on 1)

The air conditioning system of claim 1, wherein a discharge side of the cooling blower is connected to a cooling inlet of the cooling duct, and an introduction side of the cooling blower is connected to a circulation duct communicated with an interior of the vehicle.

### Claim 6 (depends on 5)

The air conditioning system of claim 5, wherein an interior air discharge hole connected to the cooling blower is formed in the circulation duct such that the interior air is discharged, and an opening/closing door is provided in the interior air discharge hole such that introduction of the interior air or the exterior air into the cooling blower is adjusted.

### Claim 7 (depends on 6)

The air conditioning system of claim 6, wherein the opening/closing door comprises a rotary door provided with a rotary shaft, and an amount of interior air or exterior air introduced into the cooling blower is adjusted according to rotation of the opening/closing door.

### Claim 8 (depends on 1)

The air conditioning system of claim 1, further comprising a filter housing connected to inlet sides of the cooling blower and the heating blower and provided with an opening at an upper end thereof such that a filter is attached to and detached from the filter housing in an upward/downward direction of a vehicle body.

### Claim 9 (depends on 8)

The air conditioning system of claim 8, wherein the filter housing is communicated in an air introduction direction of the cooling blower or the heating blower.

### Claim 10 (depends on 8)

The air conditioning system of claim 8, wherein the cooling blower or the heating blower is located in an engine room of the vehicle, and a hood extending in an introduction direction of air for preventing introduction of foreign substances is provided at an upper portion of an introduction side of the cooling blower or the heating blower.
