Abstract: A vehicle cabin air conditioning system includes a cabin indoor air conditioner and an individual air conditioner configured to condition air in a target space inside a cabin. The individual air conditioner includes a blower, a heat generator, a supply port, and an exhaust port. The supply port supplies one of a cold air cooled with the heat generator and a warm air heated with the heat generator to the target space. The exhaust port provides the other of the cold air and the warm air to outside of the target space. The cabin indoor air conditioner includes a cabin blower, a temperature control unit, and a suction port through which air is sucked for the temperature control unit. An air flow path is provided to guide air sent from the exhaust port of the individual air conditioner to the suction port of the cabin indoor air conditioner.

Abstract: The seat air conditioner configured to supply conditioning air to a seat in a vehicle cabin includes a refrigeration cycle, an air blower, and a conditioning air supply unit. The refrigeration cycle includes a compressor that compresses and discharges a refrigerant, a heat emitting portion that emits heat of the refrigerant discharged from the compressor to generate a warm air, a decompressor that decompresses the refrigerant flowing out of the heat emitting portion, and a heat absorbing portion that evaporates the refrigerant decompressed by the decompressor to generate a cold air. The air blower blows air to exchange heat with the refrigerant. The conditioning air supply unit supplies each of the warm air generated by the heat emitting portion and the cold air generated by the heat absorbing portion as the conditioning air to the seat.

Abstract: A seat air-conditioning system includes a plurality of seat air-conditioning devices respectively disposed for seats. Each of the seat air-conditioning devices achieves comfortable air conditioning in a vehicle interior by a controller controlling a refrigeration circuit, a blower, and a blowing switching portion in each seat air-conditioning device. A coordinating flow path is disposed to fluidly connect the blowing switching portion of one seat air-conditioning device to the blowing switching portion of the other seat air-conditioning device. The seat air-conditioning system performs the air conditioning for one seat by using the two seat air-conditioning devices by supplying conditioned air via the coordinating flow path under control of the controller.

Abstract: An attachment structure is for attaching a compressor to an attachment surface of an attachment target member. The compressor is a scroll type compressor and has a housing, a fixed scroll and a movable scroll. The housing is fixed to the attachment surface. The fixed scroll is fixed inside the housing and has a fixed-side tooth having a scroll shape. The movable scroll has a movable-side tooth having a scroll shape and engaging with the fixed-side tooth. The movable scroll revolves with respect to the fixed scroll. A central axis around which the movable scroll revolves is parallel with the attachment surface. A vibration direction, which is included in a radial direction of the compressor and in which a vibration component becomes largest, is different from a normal direction when viewed in an axial direction of the central axis.

Abstract: A seat air conditioner includes a housing disposed in a space formed below a seating portion of a seat and above a cabin floor surface inside a cabin. The housing houses: a compressor that compresses and discharges a refrigerant; a condenser that dissipates heat from the refrigerant discharged from the compressor; a decompressor that decompresses the refrigerant flowing out of the condenser; an evaporator that evaporates the refrigerant decompressed by the decompressor; and an air blower that blows air to be heat-exchanged with the refrigerant. The air blower is capable of drawing the air through a ventilation opening formed on an upper face of the housing.

Abstract: A vehicular air conditioner includes a first outlet that blows a conditioned air frontward to flow past a neck part of an occupant on a seat, and a second outlet that is provided below the first outlet and blows the conditioned air upward to flow past an armpit part of the occupant. The second outlet blows the conditioned air to merge with the conditioned air blown from the first outlet. The second outlet blows the conditioned air with an airflow volume larger than an airflow volume of the conditioned air from the first outlet such that the conditioned air blown from the second outlet guides the conditioned air blown from the first outlet to flow along a face of the occupant.

Abstract: An air conditioner includes a blower unit, a blowing duct, and an air switching portion. The blower unit is configured to blow cold air and warm air simultaneously. The blowing duct includes a target blowing portion through which air is sent to a space that is an air-conditioning target, and a non-target blowing portion through which the air is sent to a space that is not an air-conditioning target. The air switching portion is configured to switch between a cold air supply state in which the cold air is sent to the target blowing portion while the warm air is sent to the non-target blowing portion, and a warm air supply state in which the warm air is sent to the target blowing portion while the cold air is sent to the non-target blowing portion.

Abstract: A discharge chamber, into which refrigerant compressed by a compression mechanism, is discharged, is formed in an inside of a housing. A resonator is connected to an intermediate portion of a communication passage, which communicates between the discharge chamber and a discharge port of the housing. The resonator includes a resonance chamber and an inlet passage. The inlet passage has one end portion, which is connected to the intermediate portion of the communication passage, and another end portion, which is connected to the resonance chamber.
