    Abstract: A refrigeration cycle device has a compressor, a radiator, a decompressor, an evaporator, a heat medium cooling evaporator, a cooling target device, a detector, and a controller. The heat medium cooling evaporator cools a cooling heat medium by performing a heat exchange between the refrigerant decompressed in the decompressor and the cooling heat medium. The cooling heat medium cools the cooling target device. The detector detects a subcooling state of the cooling target device having a temperature lower than or equal to a reference temperature. Upon the detection of the subcooling state in the cooling target device by the detector, the controller increases the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger as compared to the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger when the detector does not detect the subcooling state.

    Abstract: A refrigeration cycle device includes a compressor, a condenser, a first decompressor, an outside heat exchanger, and an evaporator. A predetermined part of a refrigerant passage from the condenser to the first decompressor through which the refrigerant flows is a condenser outlet portion. A predetermined part of a refrigerant passage from the first decompressor to the outside heat exchanger through which the refrigerant flows is an outside heat exchanger inlet portion. A predetermined part of a refrigerant passage from the outside heat exchanger to the second decompressor through which the refrigerant flows is an outside heat exchanger outlet portion. A volume capacity of the condenser outlet portion is larger than a volume capacity of the outside heat exchanger inlet portion.

    Abstract: A vehicle air conditioning apparatus includes: at least one processor programmed to control a flow rate of at least one of a heat medium and outside air flowing through a heat medium-to-outside air heat exchanger such that a temperature of blast air cooled in an air-cooling heat exchanger is adjusted toward a first target temperature, and to control a flow rate of a refrigerant discharged from a compressor such that a temperature of blast air, which has been adjusted in at least one of the air-cooling heat exchanger and an air-heating heat exchanger and which is blown out into a vehicle interior, is adjusted toward a second target temperature. Accordingly, a surface temperature of the air-cooling heat exchanger and the temperature of the blast air into the vehicle interior can be properly controlled.

    Abstract: A flow passage switching unit includes side-by-side arranged rotary valve parts. The valve part includes a casing, side walls, a peripheral wall, first fluid ports, a second fluid port, a rotary shaft, and a valving element. A flow passage, through which the first fluid ports and the second fluid port selectively communicate, is formed by rotation of the valving element. The unit includes a driving mechanism driving each valving element by its corresponding predetermined rotation angle. The driving mechanism includes one driving source, and a motive power transmission member transmitting rotation motive power of the driving source respectively to the valve parts. Motive power of the driving source is transmitted to each rotary shaft of the valve parts to drive each valving element to a position, which position of the valving element relative to the first and second fluid ports is different from one another among the valve parts.

    Abstract: An air conditioner for a vehicle includes a pump that draws and discharges a heat medium, a cooler core that exchanges sensible heat between the heat medium and ventilation air into a vehicle interior to cool and dehumidify the ventilation air, a heat-medium and outside-air heat exchanger that exchanges sensible heat between the heat medium and outside air, a compressor adapted to draw and discharge a refrigerant in a refrigeration cycle, a heat-medium cooling heat exchanger that cools the heat medium by exchanging heat between a low-pressure side refrigerant in the refrigeration cycle and the heat medium, and first and second switching valves that switch between a first dehumidification mode for circulation of the heat medium between the cooler core and the heat-medium cooling heat exchanger and a second dehumidification mode for circulation of the heat medium between the cooler core and the heat-medium and outside-air heat exchanger.

    Abstract: An air conditioner includes: a heat-medium air heat exchanger that exchanges sensible heat between a heat medium having a temperature adjusted by the heat-medium temperature adjuster and ventilation air blowing to a space to be air-conditioned; a heat transfer portion having a flow path through which the heat medium circulates to transfer heat with the heat medium having the temperature adjusted by the heat-medium temperature adjuster; a large-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat transfer portion; and a small-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat-medium air heat exchanger. The small-inner-diameter pipe has small inner diameters ϕH and ϕC, compared to the large-inner-diameter pipe.
