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.

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.

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.

Seat air conditioner

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.

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.

Seat air-conditioning system

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.

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.

Attachment structure for compressor

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.

A power supply device includes a refrigeration cycle having a compressor, a motor, an inverter-integrated charger, a heat exchanger unit, and a controller having a determining unit. The inverter-integrated charger selectively controls operation of the motor using electrical power of a battery and charge of the battery with external power. The heat exchanger unit cools a cooling-necessary part of the inverter-integrated charger using refrigerant in the refrigeration cycle. When the vehicle is stopped and the battery is charged with the external power, the controller makes the inverter-integrated charger serve as: a charger to perform the charge of the battery; or an inverter to control the operation of the motor, thereby driving the compressor, upon determination that the cooling-necessary part needs to be cooled by the determining unit.

A damper device is coaxial with a central axis of an electric compressor. The damper device includes a base portion and first and second weight portions. The base portion is configured to be fixed to a casing of the electric compressor. The first and second weight portions are oscillatable relative to the base portion.

Damper device for rotating machine

A stationary base plate includes a sub-bypass hole, which communicates between a suction chamber and a first compression chamber, and a main bypass hole, which communicates between the suction chamber and a second compression chamber. A rotational center of the orbiting scroll and the sub-bypass hole are located along a first imaginary line. The rotational center of the orbiting scroll is also located along a second imaginary line, which is perpendicular to the first imaginary line. The main bypass hole opens at a location of the stationary base plate, which is on a side of the second imaginary line where the sub-bypass hole is located, so that timing of communicating between the suction chamber and the first compression chamber with each other is deviated from timing of communicating between the suction chamber and the second compression chamber with each other.

In a fluid apparatus used as a compressor, a swing support member is constructed of a hook-type adjustable joint, and supports a swing member in capable of swinging while restricting the swing member from rotating about a center axis of a shaft of the compressor. A variable mechanism portion is constructed of a rotary member rotatable around the shaft, the swing member and the like. A slant center around which the swing member swings is made to substantially correspond to a center of gravity of the variable mechanism portion. Therefore, a slant moment, for changing a slant angle of the swing member, is not structurally generated. Accordingly, even when the compressor operates, large vibration and large noise can be prevented, thereby improving durability of the compressor.
