A vehicle air conditioning device includes a compressor, a radiator, an outside heat exchanger, an evaporator, a first decompressor, a second decompressor, a switching portion, and a controller. The radiator exchanges heat between a refrigerant discharged from the compressor and air. The outside heat exchanger exchanges heat between outside air and the refrigerant flowing out of the radiator. The evaporator is exchanges heat between the refrigerant flowing out of the outside heat exchanger and the air flowing through the radiator. The switching portion switches between a series dehumidifying-heating mode and a parallel dehumidifying-heating mode. The controller is configured to control the switching portion to switch from the parallel dehumidifying-heating mode to the series dehumidifying-heating mode when the amount of the refrigerant oil flowing from the outside heat exchanger to the compressor is insufficient in the parallel dehumidifying-heating mode.

An air conditioning system for a vehicle including an air curtain assembly. The air curtain assembly includes an outer blower configured to generate an air curtain, and an inner blower configured to generate comfort airflow within the air curtain. The air conditioning system is configured to condition the comfort airflow with respect to at least one of the following: temperature, humidity, odor, particulate matter content, biological matter content, germ content, and infectious agent content.

An air purification device for a vehicle includes: a sorption device provided with a sorbent; an air intake duct for sucking air in a vehicle cabin; an outlet-side three-way valve connected to the sorption device; an air supply duct for blowing air into the cabin; an exhaust duct for discharging air to outside of the cabin; a blower; a heater; and a controller. The controller selectively executes a purification mode in which air in the cabin is sent into the sorption device at a purification temperature, and purified air from which moisture and carbon dioxide have been removed by the sorbent is blown into the cabin, and a first regeneration mode in which air heated to a first regeneration temperature is sent into the sorption device, and exhaust air containing moisture and carbon dioxide released from the sorbent is discharged to the outside of the cabin.

The disclosure describes a system and method for the environmental control of a vehicle having a cargo area and an environmentally controlled passenger area with a partition between the passenger area and the cargo area. The environmental control being directed and performed by an environmental control unit that can include one or more fans, a control module, a mounting plate, and a directional manifold to control the direction of the airflow. The environmental control unit can be installed using a method that includes attaching a fan unit to the mounting plate, connecting the fan unit to the control module, coupling to the fan unit and/or the control module to a power supply, and attaching a directional manifold to control the direction of airflow in or out of the fan unit.

An air conditioning device for a vehicle includes a first flow path through which air subject to dehumidification flows, a second flow path through which air for recovery flows, a desiccant part and a controller. The desiccant part is fluidly communicated with the first and second flow paths, and configured to adsorb moisture contained in the air subject to dehumidification, and to discharge the moisture to the air for recovery. The controller is configured to control an air volume of the air subject to dehumidification and an air volume of the air for recovery so that the air volume of the air for recovery is less than the air volume of the air subject to dehumidification, after the air volume of the air for recovery reaches a prescribed air volume for achieving a target dehumidification amount of the air subject to dehumidification.

A heat pump system for a vehicle includes a cooling apparatus including a radiator, a first water pump, a first valve, and a reservoir tank, a battery cooling apparatus including a battery coolant line connected to the reservoir tank through a second valve, a second water pump and a battery module, a chiller in a first branch line and connected to the battery coolant line through the second valve, a heating apparatus including a first connection line connected to the coolant line through a second valve, and a third water pump and a heater in the first connection line, an air conditioner including a second connection line connected to the battery coolant line through a fourth valve, and a fourth water pump and a cooler in the second connection line, and a centralized energy device connected to the first and second connection lines.

A vehicle air conditioner capable of making a determination that the dehumidification is unnecessary in a vehicle interior early to make a prompt transition from a dehumidifying mode to a heating mode and reduce power consumption is provided. A control device executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator, decompress the refrigerant, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, and a dehumidifying mode to let the refrigerant flow into the outdoor heat exchanger without flowing to the radiator to radiate heat therein, decompress the refrigerant, and then let the refrigerant absorb heat in a heat absorber 9 and let an auxiliary heater 23 generate heat. The control device shifts from the dehumidifying mode to the heating mode on the basis of the heat absorber suction air temperature Tevain being lowered more than a target heat absorber temperature TEO.

A blowing device includes a passage member and a passage switching device. The passage member is inserted into an air passage configured to blow a main air into the vehicle cabin. The passage member is configured to blow an added-value air. The passage member includes, in the air passage, a passage opening portion through which the added-value air is blown toward a passenger separately from the main air. The passage member defines a hole portion and the passage switching device is a damper or a rotary door. The damper or the rotary door closes the hole portion to allow the added-value air to flow out through the passage opening portion and fluidly connects the hole portion to the air passage to allow the main air to flow out through both the passage opening portion and a region of the air passage other than the passage opening portion.

A vehicle air-conditioning apparatus is provided which is capable of efficiently eliminating or suppressing fogging of a window while comfortably heating a vehicle interior. A controller changes and executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, and a dehumidifying and heating mode to let the refrigerant discharged from the compressor radiate heat in the radiator and let the refrigerant absorb heat in a heat absorber 9. When the temperature of air blown out to the vehicle interior is not capable of reaching a target outlet temperature in the dehumidifying and heating mode, the controller actuates a window heater 35 heating a front window 30 and shifts to the heating mode.
