    摘要： The waste heat from a heating part mounted on a vehicle is recovered and extracted by a refrigerant for gas injection so that the heating capacity at a low ambient temperature may be effectively improved while suppressing an increase in the power consumption. At the heating time, the refrigerant is circulated in a closed circuit composed of a compressor, an indoor heat exchanger, a pressure regulator and an outdoor heat exchanger, and the refrigerant, as condensed in the indoor heat exchanger, is regulated to an intermediate pressure by a pressure regulator and introduced into a heat exchanger. In this heat exchanger, the refrigerant extracts the heat from the heating part at the side of the vehicle so that it evaporates. The refrigerant thus having evaporated is introduced through an evaporation pressure regulating valve via a gas injection passage into a gas injection port of the compressor.

    摘要： In a refrigerant cycle system, a gas-liquid separator has a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has an open end opened in a gas-refrigerant area in the gas-liquid separator, a first suction hole, provided in a liquid-refrigerant area of the gas-liquid separator, for sucking liquid refrigerant containing lubricating oil, and a second suction hole provided in the gas-refrigerant area of the gas-liquid separator. The second suction hole for sucking gas refrigerant is formed in the gas-suction pipe at a downstream refrigerant side of the first suction hole. Therefore, a flow rate of gas refrigerant passing through around the first suction hole in the gas-suction pipe is decreased due to introduction of gas refrigerant by the second suction hole, thereby decreasing quantity of liquid refrigerant sucked from the first suction hole. Thus, liquid refrigerant is prevented from excessively returning to the compressor, even if the first suction hole is enlarged.

    摘要翻译： 在制冷剂循环系统中，气液分离器具有用于将气体制冷剂从气 - 液分离器引入压缩机的吸气管。 吸气管具有在气液分离器的气体制冷剂区域中敞开的开口端，设置在气液分离器的液体制冷剂区域中的用于吸入含有润滑油的液体制冷剂的第一吸入孔， 以及设置在气液分离器的气体制冷剂区域中的第二吸入孔。 用于吸入气体制冷剂的第二吸入孔形成在第一吸入孔的下游制冷剂侧的吸气管中。 因此，由于吸入管中的第一吸入孔周围的气体制冷剂的流量由于第二吸入孔引入气体制冷剂而降低，从而减少从第一吸入孔吸入的液体制冷剂的量。 因此，即使第一吸入孔扩大，也能够防止液体制冷剂过度地返回压缩机。

    摘要： An electric compressor having a compression unit and an electric motor is mounted to a vehicle through a first support member supporting the compression unit and a second support member supporting the motor. A spring constant of the first support member is smaller than that of the second support member. Therefore, vibration of the compression unit is absorbed by the first support member, and is restricted from being transmitted to the vehicle. On the other hand, vibration of the vehicle is absorbed by the second support member, and is restricted from being transmitted to the compressor. As a result, inlet and outlet pipes connected to the compressor are insulated from a large amount of stress and therefore are not broken due to fatigue at an early stage.

    摘要翻译： 具有压缩单元和电动机的电动压缩机通过支撑压缩单元的第一支撑构件和支撑电动机的第二支撑构件安装到车辆。 第一支撑构件的弹簧常数小于第二支撑构件的弹簧常数。 因此，压缩单元的振动被第一支撑构件吸收，并且被限制为传递到车辆。 另一方面，车辆的振动被第二支撑构件吸收，并且被限制不被传递到压缩机。 结果，与压缩机连接的入口管和出口管被大量应力绝缘，因此在早期阶段由于疲劳而不会破裂。

    摘要： In the cooling operation, it is determined whether supplied electric current (IDC) supplied to an electric motor for driving a compressor is less than a predetermined value or not, that is, whether consumed electric power of the electric motor is less than a predetermined value or not. In the cool-down control, the determination may be "NO", however, in this case an inverter is controlled so that the IDC is set to the predetermined value. Thus, in the present invention, since IDC is always the predetermined value a1 or less and the consumed electric power of the electric motor is always the predetermined value or less, coefficiency of performance (COP) of the refrigerating cycle can be maintained to a predetermined magnitude.

    摘要： According to the present invention, when the inside air circulation mode is determined, the blower for blowing air to the heat exchanger is operated with the regular blower voltage. When the outside air introduction mode is determined, the blower is operated with the lower blower voltage lower than the regular blower voltage. As a result, consumed electric power of a compressor in the outside air introduction mode can be controlled and the deterioration of the efficiency of the refrigerating cycle in the inside air circulation mode can be prevented.

    摘要： An air-conditioning apparatus that prevents a state of blowing temperature fluctuation due to magnitude of vehicle speed in a dehumidification mode. A condenser and evaporator are disposed within an air duct, and an exterior heat exchanger is disposed externally. A capillary and check valve are provided in a refrigerant passage between the condenser and exterior heat exchanger, and a capillary is provided in a refrigerant passage between the exterior heat exchanger and evaporator. During dehumidification mode, a four-way switching valve is switched so that the flow passage of refrigerant is from the condenser to the capillary, to the check valve, to the exterior heat exchanger, to the capillary, to the evaporator, and then to an accumulator. In this case, the condenser and exterior heat exchanger function as a refrigerant condenser in a series-connected state, but because in actuality the capillary is provided, the majority of refrigerant discharged from a compressor is condensed by the condenser.

    摘要： The invention prevents the temperature of supplied air from being decreased by a defrosting operation when a vehicle is in operation. During the heating operation, it is judged whether the vehicle is in operation. When the vehicle is in operation, it is judged whether an external heat exchanger is frosted or not relying upon the external air temperature, temperature of the external heat exchanger (coolant) and the time of heating operation. When it is judged that frost is formed, the rotational speed of the compressor is increased to increase the ability to supplying the coolant, to maintain heating ability and to prevent the drop of temperature of the supplied air. When the frost is formed after the operation of the vehicle has been finished, it is judged whether the secondary batteries are being charged or not, i.e., whether the charging circuit of the secondary batteries is connected to the external power source for charging or not. When it has not been connected, the device waits until it is connected, and the defrosting operation is executed at a moment when the charging circuit is connected.
