Air-conditioning system for vehicle and control method thereof

Abstract

An air-conditioning system (A1) for a vehicle and an air-conditioning system (A2) for a battery, according to the present invention, can be made compact and can enhance the comfort level of heating and properly control the temperature of a battery by delivering air cooled through a first evaporator (400) of a heating / cooling module (D1), or air heated through a condenser (200), to a supply side (toward a passenger or a battery). In this case, the heating / cooling module (D1) comprises: a compressor (100) that suctions and compresses a refrigerant; the condenser (200) that condenses the refrigerant that is compressed in the compressor (100); an expansion means (300) that controls the flow of the refrigerant that is condensed in the condenser (200); the first evaporator (400) that evaporates the refrigerant that is supplied through the expansion means (300); a (1-1)th blowing unit (500) that blows out air such that the air is cooled while passing through the first evaporator (400); a (1-2)th blowing unit (600) that blows out air such that the air is heated while passing through the condenser (200); and a delivery duct (700) for delivering, toward a passenger, the air that is selectively supplied by an opening / closing means (800) through the (1-1)th blowing unit (500) and the (1-2)th blowing unit 600).

Description

technical field [0001] The present invention relates to an air conditioning system for a vehicle and a control method thereof, and more specifically, to an air conditioning system for a vehicle and a control method thereof that can perform cooling and heating in the vehicle interior by using one module, or can Realize cooling of the battery, realize miniaturization, and facilitate installation. Background technique [0002] The air-conditioning system for vehicles is an automotive interior component used to cool and heat the interior of the car in summer or winter, or to remove frost from the windshield in rainy or winter weather, so that the driver can ensure that the front and rear This kind of air-conditioning system usually has heating system and cooling system at the same time, so the outside air or inside air is selectively introduced and heated or cooled, and then the air is sent to the room, so that the car interior Cool, heat or ventilate. [0003] figure 1 It is...

Problems solved by technology

[0006] However, the conventional air-conditioning system for vehicles uses engine cooling water for heating, and the non-starting air-conditioning system for vehicles requires an independent heater for performing heating when the engine is not in operation.
