摘要： Provided is a vehicular refrigerating cycle comprising a compressor, which uses carbon dioxide refrigerant and which has a displacement control valve capable of controlling a displacement in response to an external signal. The vehicular refrigerating cycle comprises a falling-off preventing means for stopping a movement of the displacement control valve in a direction in which the displacement control valve comes out of its mounting position on the compressor, disposed at a portion which is positioned in the direction for the displacement control valve to come out of its mounting position on the compressor and positioned on this side of a position for the displacement control valve to completely fall off from the compressor. The displacement control valve can be prevented from exerting unpreferred influences upon the environment, even if the displacement control valve being mounted on the compressor should become so unfixed for some reason as could pop out of the compressor.

摘要： There is provided a car air conditioner with a high COP, low GWP and high reliability. A simple refrigerant R32 is filled in a refrigerant circuit 1 of the car air conditioner. This simple refrigerant R32 has a high COP and low GWP, but is easily polarized and produces contaminants and sludge. However, these contaminants and sludge hardly block a motor-driven expansion valve 6 or the like due to vibration and impact of a car. Therefore, this car air conditioner has high reliability. Furthermore, since the simple refrigerant R32 is a simple substance, recycling after collection is easy.

摘要： In a refrigerating cycle device using carbon dioxide as a refrigerant, there exists a problem that the provision of a receiver at a low-pressure side increases cost and volume due to a pressure resistance design necessary for ensuring safety. By adjusting a refrigerant holding quantity of a first heat exchanger in such a manner that a refrigerant pressure of the first heat exchanger 13 is changed by operating a first decompressor 12 and a second decompressor 15, an imbalance of a refrigerant quantity between time for space cooling and time for heating or dehumidifying can be alleviated and hence, it is possible to perform an operation of the refrigerating cycle device with high efficiency with a miniaturized receiver or without providing the receiver.

摘要： The object of the present invention is to prevent refrigerant from flowing out into a vehicle compartment due to damage to an evaporator or piping associated therewith. A solenoid valve is arranged at an inlet of an evaporator, and a check valve is arranged at an outlet of the evaporator. When operation of a system is to be stopped, the solenoid valve is closed while a compressor is kept operating for a predetermined time to suck out refrigerant from the evaporator to a downstream side of the check valve, so that during stoppage of the operation, the check valve prevents the refrigerant from flowing back into the evaporator. Thus, even if the evaporator arranged in the vehicle compartment or piping associated therewith is damaged, a situation where a large amount of refrigerant flows out of the evaporator into the vehicle compartment does not occur because no refrigerant remains in the evaporator, making it possible to prevent occupants in the vehicle compartment from being put in a grave situation.
摘要翻译：本发明的目的是防止制冷剂由于与其相关联的蒸发器或管道的损坏而流出到车厢内。电磁阀设置在蒸发器的入口处，并且在蒸发器的出口处布置有止回阀。当停止系统的操作时，在压缩机保持运行预定时间以将制冷剂从蒸发器吸入止回阀的下游侧时，电磁阀关闭，使得在停止操作期间，止回阀防止制冷剂回流到蒸发器中。因此，即使布置在车辆隔室中的蒸发器或与其相关联的管道被损坏，也不会发生大量制冷剂从蒸发器流出到车厢内的情况，因为在蒸发器中没有制冷剂残留，防止车厢内的乘客处于严重状况。
