The present invention relates to a vehicular air conditioning system and provides a vehicular air conditioning system capable of preventing overheating of an inverter that controls the rotation speed of an electric compressor without cutting off the inverter, and consequently preventing the stoppage of an air conditioner due to the cut-off of the inverter and the resultant stoppage of cooling of a passenger room. The vehicular air conditioning system includes an electric compressor, an inverter configured to control a rotation speed of the electric compressor, and a control part configured to execute control so that a refrigerant flow rate on an inlet side of the electric compressor increases when a temperature of the inverter is equal to or higher than a preset overheating warning temperature.

Vehicular air conditioning system

Provided is a combination valve unit having an improved structure and capable of performing both a pressure relief function for cooling and a pressure relief function for dehumidification. In addition, disclosed is a vehicle heat pump system capable of improving dehumidification performance by actively controlling the refrigerant flow distribution. The combination valve unit serves as a refrigerant throttling means in a vehicle heat pump system, and forms the inlet for a cooling pressure relief unit for performing indoor cooling and the inlet for a dehumidification pressure relief unit for performing indoor dehumidification, respectively.

Combination valve unit and vehicle heat pump system

An embodiment relates to a heat management device for a vehicle and a heat management method for a vehicle, which use a branch line and a flow control means to use heat generated from a battery module of a vehicle or a heat generated from an electrical component of the vehicle as a heat source for an air conditioning device installed in the vehicle. Therefore, the heat management device for a vehicle and the heat management method for a vehicle may improve heating performance and quality by selectively using waste heat from the electrical component module and the waste heat from the battery depending on the mode.

Heat management device for vehicle, and heat management method for vehicle

Vehicular heat management system includes a refrigerant circulation line including a compressor, a high pressure side indoor heat exchanger, a heat pump mode expansion valve, an outdoor heat exchanger, an air conditioning mode expansion valve, low pressure side indoor heat exchanger and a refrigerant-cooling water heat exchanger; an air conditioning mode branch line branched from the refrigerant circulation line and configured to, in an air conditioning mode, form a cooling loop by circulating a refrigerant through the compressor, the high pressure side indoor heat exchanger, the outdoor heat exchanger, the air conditioning mode expansion valve and low pressure side indoor heat exchanger. Heat pump mode branch line branched from the refrigerant circulation line is configured, in heat pump mode to form a heating loop by circulating the refrigerant through the compressor, the high pressure side indoor heat exchanger, the heat pump mode expansion valve and the refrigerant-cooling water heat exchanger.

Vehicular heat management system

An air conditioning system for motor vehicles includes a compressor, a condenser, a plurality of air conditioning units connected in parallel with each other with respect to the compressor and the condenser, and a flow rate control unit configured to, when a specific one of the air conditioning units is additionally turned on or is turned off, prevent occurrence of a sudden change in refrigerant amount in the remaining air conditioning units.

Air conditioning system for motor vehicles

Disclosed herein is an air conditioner for a vehicle, which includes: an air-conditioning case () having an air passageway for connecting an air inflow port () and an air outflow port () with each other; an evaporator () and a heater core () mounted on the air passageway; a blower unit () disposed at the side of the air inflow port () to blow air to the inside of the air-conditioning case (); and a separator () disposed at the upstream side of the evaporator () to divide air, which is introduced into an air inflow passageway () of the air-conditioning case (), into the right and the left. The air conditioner further includes an assembly end portion () disposed at an end portion of one side of the separator () to be inserted and assembled on the air inflow passageway () of the air-conditioning case () by forced fitting.

Air conditioner for vehicle

Disclosed therein is a dual zone type air conditioner for a vehicle, which includes: an air volume control door mounted between a blower and an evaporator for controlling the degree of opening of first and second passageways so as to control the volume of air blown to the inside of an air-conditioning case; and bypass passageways disposed in the air volume control door to supply a predetermined air volume to a closed passageway even though the air volume control door is at the location to close the first passageway or the second passageway, thereby preventing a sudden change in air volume by widening a control interval of the air volume control door because the first-stage air volume can be realized even though the air volume control door closes one of the air passageways, and reducing a whistle noise by securing a predetermined cross-sectional area of the air passageway through the bypass passageways even though the cross-sectional area of the air passageway gets narrower while the air volume control door closes one of the air passageways.

Dual zone type air conditioner for vehicle

An individual air conditioning apparatus for a vehicle includes: a driver's seat air conditioning module and a passenger seat air conditioning module sequentially provided with an evaporation core and a heater core; a first channel that passes through the evaporation core and is connected to an indoor outlet; a second channel that passes through the evaporation core and the heater core and is connected to the indoor outlet; and a temperature control door that opens and closes the first channel and the second channel.

Individual air conditioning apparatus for vehicle and method of controlling the same

An air conditioning system for motor vehicles includes an air conditioner case, a blower installed in the air conditioner case and configured to draw an air and blow the air into a vehicle room, and a control unit configured to limit an upper limit value of a temperature of the air blown toward the blower.

An air conditioning system for motor vehicles includes an air conditioner case having a left path, a right path and a rear seat path. A temperature door is configured to adjust a volume of a cold air or a hot air. A main blower is configured to blow the cold air or the hot air and an air volume distribution door is configured to control opening degrees of the left path and the right path. A rear seat auxiliary blower is configured to increase a volume and a pressure of the cold air or the hot air flowing through the rear seat path. A control unit is configured to, when an air volume distribution ratio of the main blower is changed, correct an opening position of the air volume distribution door and compensate a change in an air volume distribution ratio of the left path and the right path.
