Abstract

Disclosed herein are air-conditioning systems for a vehicle for a battery, which can control temperature of the vehicle or the battery by delivering air cooled through a first evaporator of a cooling and heating module or air heated through a condenser to a supply side (toward a passenger or a battery). The cooling and heating module includes: a compressor; the condenser; an expansion valve for controlling a flow of the refrigerant condensed in the condenser; the first evaporator for evaporating the refrigerant supplied through the expansion valve; a first-first blowing unit for blowing air through the first evaporator; a first-second blowing unit for blowing air through the condenser; and a discharge duct for selectively delivering the air supplied through the first-first blowing unit and the first-second blowing unit toward the passenger by opening and closing means.

First claim

The invention claimed is:

1. An air-conditioning system for a vehicle comprising:
a cooling and heating module; and
a battery for operating the cooling and heating module,
wherein the cooling and heating module including:
a compressor for inhaling and compressing refrigerant;
a condenser for condensing the refrigerant compressed in the compressor;
an expansion valve for throttling the refrigerant condensed in the condenser;
a first evaporator for evaporating the refrigerant supplied through the expansion valve;
a first-first blowing part for blowing air to be cooled after passing through the first evaporator;
a first-second blowing part for blowing air to be heated after passing through the condenser; and
a discharge duct for delivering at least one of the air to be cooled and the air to be heated, which is selectively supplied through the first-first blowing part and the first-second blowing part by opening and closing means, to a supply side, the discharge duct including an outer body having a first-first inflow part, a first-second inflow part, a second-first inflow part, a second-second inflow part each for receiving the at least one of the air to be cooled and the air to be heated, wherein the opening and closing means selectively opens and closes the first-first inflow part, the first-second inflow part, the second-first inflow part, and the second-second inflow part, and wherein a first partition, a second partition, and a third partition cooperate with each other to form a first space part and a second space part on the discharge duct;

wherein the cooling and heating module further includes a base part having a first mounting recess hollowed at a first area of the base part to deliver air to the first evaporator, and a second mounting recess hollowed at a second area of the base portion to deliver air to the condenser.

2. The air-conditioning system according to claim 1 , wherein the opening and closing means delivers the air cooled after passing through the first evaporator to the supply side and discharges the air heated after passing through the condenser to the outside in a cooling state, and wherein the opening and closing means discharges the air cooled after passing through the first evaporator to the outside and delivers the air heated after passing through the condenser to the supply side in a heating state.

3. The air-conditioning system according to claim 1 , wherein the cooling and heating module is detachably mounted on the vehicle.

4. The air-conditioning system according to claim 3 , wherein the cooling and heating module is independently controllable.

5. The air-conditioning system according to claim 1 , wherein in the cooling and heating module, the supply side is an interior of the vehicle.

6. The air-conditioning system according to claim 1 , wherein in the cooling and heating module, the supply side is a battery.

7. The air-conditioning system according to claim 1 , comprising a plurality of the cooling and heating modules.

8. The air-conditioning system according to claim 7 , wherein the cooling and heating modules are a first cooling and heating module disposed under a first seat on which a driver sits; a second cooling and heating module disposed under a second seat which is adjacent to the first seat in a width direction of the vehicle; a third cooling and heating module disposed under a third seat which is adjacent to the first seat in a length direction of the vehicle; and a fourth cooling and heating module disposed under a fourth seat which is adjacent to the third seat in the width direction of the vehicle.
