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： A heat pump air conditioner has a heat exchanger, a separator for separating refrigerant discharged from the heat exchanger into gas refrigerant and liquid refrigerant, and a compressor. Gas refrigerant in the separator is sucked into the compressor through a gas suction pipe. Oil-dissolved liquid refrigerant in the separator is also sucked through an oil return hole formed at a bottom of the gas suction pipe into the compressor. At the time of starting the air conditioner, when it is judged that a surface of liquid refrigerant in the separator is rapidly lowered to the oil return hole, a rotational speed of the compressor is controlled so that an amount of refrigerant discharged from the compressor is decreased. As a result, the surface of liquid refrigerant is kept higher than the oil return hole, and oil shortage of the compressor is restricted.

摘要： A refrigerant cycle system includes a gas-liquid separator for separating gas-liquid refrigerant into gas refrigerant and liquid refrigerant. The gas-liquid separator has a liquid-suction pipe for introducing liquid refrigerant from the gas-liquid separator to a decompressing unit, and a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has a suction hole for sucking liquid refrigerant therein, and the suction hole is provided at a position lower than an open end of the liquid-suction pipe. Because a height of a surface of liquid refrigerant in the gas-liquid separator is constantly equal to or higher than the open end of the liquid-suction pipe regardless of change in a heating load of the refrigerant cycle, liquid refrigerant is constantly sucked into the gas-suction pipe from the suction hole. Thus, liquid refrigerant in which lubricating oil is dissolved can be constantly introduced into the compressor, thereby preventing shortage of lubricating oil in the compressor. On the other hand, in the refrigerant cycle, an oil-discharging mode is selectively set at a starting time of a heating mode so that lubricating oil staying in an evaporator is discharged. Therefore, lubricating oil is sufficiently returned to the compressor even when the heating mode is switched from a cooling mode.

摘要： An air conditioner system for vehicles has an exterior heat exchanger, which is used as an evaporator at the time of heating operation. A control unit monitors the heating operation and stores a defrost flag when the heating operation continues for a predetermined time period, e.g., 20 minutes, under a low exterior air temperature below a predetermined temperature, e.g., 5° C. When an electric vehicle is at rest after the heating operation to charge its secondary battery with an electric power from an external power source, the control unit first starts a defrosting operation and starts a charging operation of the secondary battery after the completion of the defrosting operation.

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： An air conditioning system that can operate an air conditioner of an electric vehicle without interfering with the charging process, which utilizes a secondary battery. When operation of the vehicle is terminated and the control system determines that a frosting judgment decision is positive, the control system judges whether the charging current has dropped to a specified level or less. As soon as the charging current has dropped to or below the specified level, the excess charging current may be used for a defrosting operation. When the operation of the vehicle is stopped and the control system determines that a frosting judgment decision is negative, the control system judges whether a preliminary air conditioning switch is on. If the preliminary air conditioning switch is on, it is judged whether charging of the secondary battery is in progress. If charging is progressing, the control system determines whether the charging current has dropped to or below a specified level. As soon as the charging current has dropped to or below this specified level, preliminary air conditioning is performed to cool or warm the cabin of the vehicle during charging of the secondary battery.

摘要： In an ejector cycle system using carbon dioxide as refrigerant, an ejector decompresses and expands refrigerant from a radiator to suck gas refrigerant evaporated in an evaporator, and converts an expansion energy to a pressure energy to increase a refrigerant pressure to be sucked into a compressor. Because refrigerant is decompressed and expanded in a super-critical area, a pressure difference during the decompression operation becomes larger, and a specific enthalpy difference becomes larger. Accordingly, energy converting efficiency in the ejector becomes higher, and efficiency of the ejector cycle system is improved.

摘要： A gas-injection type refrigeration-cycle device has heat exchanger where refrigerant extracts waste heat from heating devices. In the refrigeration-cycle device, the mode is changed between where lower-pressure refrigerant extracts heat and where intermediate-pressure refrigerant extracts the heat of the hot water. The lower-pressure refrigerant is drawn into compressor, after heat exchanger is set at the lower-pressure side of the refrigeration cycle. The intermediate-pressure refrigerant is introduced into compressor-gas-injection port, after heat exchanger is set at the intermediate-pressure side of the refrigeration cycle. In another aspect, a defrosting mode of outdoor heat exchanger includes a heating mode, and gas refrigerant discharged from compressor flows through condenser without heat exchange. Thereafter, the flow of the gas refrigerant is divided to two portions, and the gas refrigerant of one portion flows into outdoor heat exchanger, thereby defrosting outdoor heat exchanger. The other portion flows into evaporator, thereby heating blown air within an air-conditioning duct by evaporator.

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.
