    Abstract: A heater core for performing heat exchange between a coolant and ventilation air to be blown to the interior of a vehicle so as to heat the ventilation air is disposed in a water circulation circuit for circulating a coolant in an engine EG for outputting driving force necessary to move the vehicle. When the temperature of the coolant discharged from the engine EG is low, a heat transport refrigeration cycle device, serving as a heat transport unit for absorbing heat from a downstream coolant at a position downstream more than the heater core and dissipating the heat absorbed from the downstream coolant to an upstream coolant at a position upstream more than the heater core, is operated to increase the temperature of the coolant introduced into the heater core until the temperature of the coolant reaches the temperature necessary to heat the interior of the vehicle, without operation of the engine EG.

    Abstract: A refrigeration cycle device includes a compressor, an upstream branch portion, a heating portion, a decompression portion, a bypass passage, a bypass flow adjustment portion, and a mixing portion. The mixing portion mixes a bypass side refrigerant flowing out from the bypass flow adjustment portion with a decompression-portion side refrigerant flowing out from the decompression portion, and causes the mixed refrigerant to flow to a suction port side of the compressor. The mixing portion mixes the bypass side refrigerant and the decompression-portion side refrigerant such that an enthalpy difference obtained by subtracting an enthalpy of an ideal homogeneously mixed refrigerant from an enthalpy of a suction side refrigerant actually sucked into the compressor is equal to or less than a predetermined reference value.

    Abstract: A refrigerant cycle device includes a first refrigerant passage for guiding refrigerant from a refrigerant radiator to an inlet side of an outdoor heat exchanger, a first throttle part capable of varying an opening area of the first refrigerant passage, a second refrigerant passage for guiding the refrigerant from the outdoor heat exchanger to a compressor-suction side, a first opening/closing part for opening/closing the second refrigerant passage, a third refrigerant passage for guiding the refrigerant from the outdoor heat exchanger to the compressor-suction side via an evaporator, a second throttle part capable of varying an opening area of the third refrigerant passage, a bypass passage for guiding the refrigerant flowing between the refrigerant radiator and the first throttle part to a position between the outdoor heat exchanger and the second throttle part in the third refrigerant passage, and a second opening/closing part for opening/closing the bypass passage.

    Abstract: When a refrigerant evaporation temperature of an interior evaporator cannot be set lower than a dew-point temperature of air flowing into the interior evaporator in a heating operation, a refrigerant circuit is switched to a normal heating operation mode in which a flow rate of the refrigerant flowing into the interior evaporator is set to zero by allowing the refrigerant to flow toward a bypass passage. In a case where the air cannot be dehumidified by the interior evaporator, an unnecessary heat exchange between the air and the refrigerant in the interior evaporator can be suppressed. Thus, the energy of the vehicle air conditioner can be effectively prevented from being wasted.

    Abstract translation: 当内部蒸发器的制冷剂蒸发温度不能设定为低于在加热操作中流入内部蒸发器的空气的露点温度时，制冷剂回路切换到常规加热操作模式，其中制冷剂的流量 通过允许制冷剂流向旁路通道，流入内部蒸发器的流量被设定为零。 在空气不能被内部蒸发器除湿的情况下，可以抑制内部蒸发器中的空气和制冷剂之间的不必要的热交换。 因此，可以有效地防止车辆空调的能量的浪费。

    Abstract: In an integration valve, a body, in which a vapor-liquid separating space is provided, includes a fixed throttle decompressing liquid-phase refrigerant, a liquid-phase refrigerant side valve body member opening or closing a liquid-phase refrigerant passage, and a vapor-phase refrigerant side valve body member opening or closing a vapor-phase refrigerant passage. Further, the vapor-phase refrigerant side valve body member is configured by a differential pressure regulating valve operated based on a pressure difference between a refrigerant pressure at a side of the vapor-phase refrigerant passage and a refrigerant pressure at a side of the liquid-phase refrigerant passage. The vapor-phase refrigerant side valve body member is movable when the liquid-phase refrigerant side valve body member is moved by a solenoid. Therefore, a cycle configuration of a heat pump cycle configuring a gas injection cycle can be simplified.
