    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. According to the refrigeration cycle device, preferable coefficient of performance of cycle can be achieved in different operation modes.

    Abstract: A thermal management device includes a waste-heat supply device that supplies waste heat to a heat medium flowing through a second heat medium path portion, a heater core that exchanges heat between air and the heat medium, a switching valve that switches between a state in which the heat medium circulates between the heater core and a first heat medium path portion and a state in which the heat medium circulates between the heater core and the second heat medium path portion, an adjustment portion that adjusts a temperature of the heat medium in the first heat medium path portion, and a controller. The controller controls the adjustment portion such that the temperature of the heat medium in the first heat medium path portion is equal to or higher than a predetermined temperature when the switching valve circulates the heat medium between the heater core and the second heat medium path portion.

    Abstract: A vehicle air-conditioning device includes a compressor, a heating unit, an outside air heat exchanger, a wind speed regulation unit, and a controller. The heating unit includes a heating heat exchanger and heats ventilation air supplied to a space to be air conditioned using a high-pressure refrigerant as a heat source. The wind speed regulation unit regulates a wind speed of air supplied to the outside air heat exchanger. The control unit performs, as a defrosting operation of defrosting the outside air heat exchanger, a dry defrosting mode for evaporating and removing frost adhering to the outside air heat exchanger in a state where the outside air is at a low temperature. In the dry defrosting mode, the controller causes the wind speed regulation unit to supply air to the outside air heat exchanger at a wind speed in a range determined to promote evaporation and removal of frost.

    Abstract: The present disclosure provides a vehicle air-conditioning device in which cooperative work with a power source is appropriate, which is easy to follow when the power source is restarted, and which reduces a driving force of a compressor at the time of restarting the power source. The vehicle air-conditioning device is provided with a refrigeration cycle. The refrigeration cycle has a compressor that is driven by a power source which may stop temporarily. The refrigeration cycle provides a low temperature and/or a high temperature. A high-temperature system and/or a low-temperature system is provided as a thermal buffer. The refrigeration cycle is provided with electric expansion valves which can be fully closed. The vehicle air-conditioning device is also provided with a control device, which fully closes the electric expansion valves when the compressor is temporarily stopped and which controls the electric expansion valves to the previous opening position when the compressor is restarted.
