A heat pump system for a vehicle is configured to perform cooling or heating of the vehicle interior by using a natural refrigerant, and efficiently adjust the temperature of the battery module by using a single chiller that heat-exchanges refrigerant and coolant.

Heat pump system for a vehicle

An embodiment heat pump system for a vehicle includes an air conditioner unit and a chiller. The air conditioner unit includes a compressor, first through third heat-exchangers, a first expansion valve, and an evaporator interconnected by a refrigerant line for circulating a refrigerant through the refrigerant line, and the chiller is connected to the refrigerant line through a first connection line for adjusting a temperature of a coolant by heat-exchanging the refrigerant with the coolant. The air conditioner unit further includes a second expansion valve on the first connection line upstream of the chiller, a first valve on the refrigerant line between the first and second heat-exchangers, a third expansion valve on the refrigerant line between the first valve and the second heat-exchanger, a second valve on the refrigerant line between the evaporator and the compressor, and a fourth expansion valve on a second connection line.

Heat pump system for vehicle

The present invention provides a vehicle air-conditioning system comprising: a pair of evaporation units which cause heat exchange between a refrigerant and air, and which are arranged to be spaced apart from each other so as to discharge cold air in different directions; one expansion valve, which expands a low-temperature and high-pressure refrigerant so as to supply same to the evaporation unit; an inlet pipe in which the refrigerant of the expansion valve moves to a first evaporation unit; a first moving pipe in which the refrigerant having circulated through one region of the first evaporation unit moves to a second evaporation unit; a second moving pipe in which the refrigerant having circulated through the second evaporation unit moves to the first evaporation unit; and an outlet pipe through which the refrigerant having circulated through the first evaporation unit flows out.

Vehicle air-conditioning system

Disclosed herein is an air conditioner for a vehicle, which can select a blower with the maximum efficiency within a range of a targeted air discharge volume for indoor circulation and select a blower with the maximum efficiency within a range of a targeted air discharge volume for outdoor discharge. The air conditioner includes: an air-conditioning case having a first air passageway and a second air passageway; an evaporator disposed on the first air passageway or the second air passageway; a condenser disposed on the first air passageway or the second air passageway; a first blower arranged on an indoor circulation passage; and a second blower arranged on an outdoor discharge passage.

Air conditioner for vehicles

The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle in which heating performance may be improved using an auxiliary heating heat exchanger and stability of a passenger may be improved by providing the auxiliary heating heat exchanger in an engine room.

Air conditioner for vehicle

The present invention relates to an air conditioner for a vehicle, which includes a cold air passageway and a warm air passageway, and two blowers disposed in the air passageways, thereby rapidly ventilating the interior of the vehicle using the two blowers.

The present invention relates to an air conditioner for a vehicle which includes an integrated heat pump system having an electronic part waste heat recovery device to enhance heating performance and which can cool a battery of an electric vehicle using refrigerant in a cooling mode. The air conditioner for a vehicle includes a refrigerant circulation system for performing cooling or heating of the interior of the vehicle by circulating refrigerant. The air conditioner further includes a first refrigerant pipe exchanging heat with a battery system of the vehicle in sequence to selectively exchange heat between refrigerant of the refrigerant circulation system and a coolant of the first coolant pipe.

A vehicle air conditioner, wherein an air conditioner of an integrated heat pump system enables the improvement of cold air and warm air mixing characteristics so as to decrease left-right temperature differences, enables the implementation of independent left-right air conditioning, and enables the sufficient securement of an interior space of the vehicle.

Vehicle air conditioner

Disclosed is a vehicle air conditioning device, which is an air conditioning device using an integrated heat pump system, and in which left and right independent air conditionings can be implemented in a simple structure such that the left and right air volumes may be automatically controlled, the ability to mix hot and cold air is improved, and sufficient space can be secured inside a vehicle.

Disclosed is a vehicle air conditioner, wherein an integrated air conditioning module using a heat pump system enables, in order to secure interior space, the optimizing of the arrangement thereof and the arrangements among the elements thereof, and the increasing of a coupling force between an air conditioning module and a distribution duct.

The present invention relates to an air conditioning system for a vehicle in which an air-conditioning module having an air-conditioning case and a blower unit is disposed at a side of an engine room relative to a dash panel, and a distribution duct having a defrost vent, a face vent, and a floor vent is disposed in the interior of a vehicle relative to the dash panel so as to distribute cold air and hot air discharged from the air-conditioning case into the interior of the vehicle, wherein the floor vent is placed on one side of an area, in which a relatively large amount of hot air flows, in a mixing chamber of the distribution duct where cold air and hot air are mixed, i.e. a side adjacent to the dash panel.

An air conditioning unit for a vehicle includes a first channel and a second channel, a blowing unit including a first blower fan and a second blower fan that rotate together by sharing a rotary shaft and a driving unit, a bypass channel, and a control door disposed among the outlets of the first channel and the second channel, the heating core, and the bypass channel to control air discharged from the first channel or the second channel to pass through the heating core or not to pass through the heating core through the bypass channel.

Air conditioning unit for a vehicle

Air conditioning system for a vehicle which includes an air-conditioning module having an air-conditioning case, which has a cold air passageway and a warm air passageway partitioned from each other, and a blower unit, and an indoor air inflow duct for introducing indoor air of the interior of the vehicle into the blower unit. An outlet of the air-conditioning case and an inlet of the indoor air inflow port are arranged to be adjacent to each other, so that the air conditioning system for a vehicle can be installed through just one through hole part formed in a dash panel.

Air conditioning system for vehicle

Disclosed is an air conditioning system for a vehicle which includes a cold air passageway having a heat exchanger for cooling and a warm air passageway having a heat exchanger for heating inside an air-conditioning case to carry out cooling and heating and which controls to inhale indoor air inside the vehicle, pass the air through the heat exchanger for cooling and discharge the air outside the vehicle in a specific mode, thereby preventing frosting of the heat exchanger for cooling because supplying air of high temperature dehumidified inside the interior of the vehicle to the heat exchanger for cooling, and enhancing heating performance by rising refrigerant pressure and temperature in the refrigerant cycle without needing additional components.
