    Abstract: An accumulator includes a tank, a desiccant, a suction pipe. The tank is configured to separate a refrigerant flowing therein into a gas-phase refrigerant and a liquid-phase refrigerant, store the liquid-phase refrigerant in the tank, and discharge the gas-phase refrigerant toward a suction side of a compressor. The desiccant is accommodated in a container and removing moisture in the refrigerant. The suction pipe is provided inside the tank and having a suction port through which the gas-phase refrigerant is sucked into the suction pipe. The desiccant is provided inside the suction pipe. According to this accumulator, a bumping due to the desiccant and an increase in size of the tank can be suppressed.

    Abstract: An air conditioner for a vehicle includes a vapor compression refrigeration cycle switchable between a heat pump cycle and a cooler cycle, a heat core configured to heat air to be blown into a vehicle compartment by using coolant of an engine of the vehicle as a heat source, and a controller configured to control operation of the vapor compression refrigeration cycle. The controller controls the vapor compression refrigeration cycle to be operated as the cooler cycle so as to perform a defrosting control of the outdoor heat exchanger, and outputs an operation request signal to the engine, when the controller determines that the outdoor heat exchanger is frosted.

    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.

    Abstract translation: 在集成阀中，设置有气液分离空间的主体包括固定节气门减压液相制冷剂，打开或关闭液相制冷剂通道的液相制冷剂侧阀体构件，以及 气相制冷剂侧阀体构件打开或关闭气相制冷剂通道。 此外，气相制冷剂侧阀体构件由基于气相制冷剂通路一侧的制冷剂压力与液相制冷剂侧阀侧的制冷剂压力之间的压差而动作的差压调节阀构成， 相制冷剂通道。 当液相制冷剂侧阀体构件通过螺线管移动时，气相制冷剂侧阀体构件可移动。 因此，能够简化构成气体注入循环的热泵循环的循环结构。
