摘要： A control apparatus for a gas injection type air conditioning system that prevents lowering of compressor speed and cycle stoppage under conditions where high pressure is liable to occur. During a system heating mode, a pressure change rate ASP of the high pressure of the refrigerating cycle is calculated. When a pressure change rate .increment.SP rises above a predetermined value, a system electric expansion valve aperture is reduced. Accordingly, by calculation of the pressure change rate .increment.SP, it is possible to control the electric expansion valve in the above manner earlier than in prior art control schemes when there is a sudden rise in the high pressure.

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.
摘要翻译：在制冷运转中，确定供给到用于驱动压缩机的电动机的供给电流（IDC）是否小于预定值，即电动机的消耗电力是否小于预定值或不。在冷却控制中，确定可以是“否”，但是在这种情况下，控制逆变器使得IDC被设定为预定值。因此，在本发明中，由于IDC始终为规定值a1以下且电动机的消耗电力始终为规定值以下，所以能够将制冷循环的性能（COP）的效率保持为规定值大小。

摘要： In an electrical compressor having a motor and an electrical circuit integrated with a compression portion, a part of electrical components of the electrical circuit is disposed in spaces between a cylindrical outer surface of a motor housing and an imaginary flat surface that imaginarily contacts the cylindrical outer surface. Therefore, the spaces can be used effectively, and the electrical compressor can be downsized. Further, the part of the electrical components can be effectively cooled by refrigerant in the motor housing. On the other hand, the outer surface of the motor housing is used as one surface defining an inner space of a casing for accommodating the electrical circuit. In this case, the electrical circuit can be effectively cooled by refrigerant in the motor housing.

摘要： In an air conditioner for a hybrid vehicle, when a residual charging degree of a battery becomes equal to or lower than a target degree, the electrical motor generator is driven by a vehicle engine so that the battery is charged through the electrical motor generator. When the engine is driven, the target degree of the battery is set higher than that when the engine is stopped so that a charging operation tends to be required while the engines driven. Accordingly, the frequency for starting the engine only for charging the battery is reduced.

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 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： According to the present invention, in a heating operation where a heating indoor heat exchanger function as a condenser and an outdoor heat exchanger functions as an evaporator, an air amount supplied by a blower is reduced when a predetermined amount of frost is or may be deposited on the outdoor heat exchanger in an outside air introduction mode where an outside air is supplied into a passenger compartment. Accordingly, a heating load is reduced to thereby reduce an endothermic amount in the outdoor heat exchanger. As a result, a frost deposition speed is reduced, and a deposited frost limit is increased, thereby extending a heating operation period.

摘要： When a defroster switch is input in a heating operation mode, an opening degree of an electric type of a heating expansion valve is controlled to be smaller when temperature of refrigerant discharged from a compressor is less than a predetermined temperature. Therefore, the supercooling degree of the liquid refrigerant of an indoor heating heat exchanger becomes large, the temperature of the heat exchanger becomes high, so that the temperature of air which is blown from a defroster outlet becomes high. Thus, the defrosting effect of a front windshield glass can be increased. Accordingly, when the defrosting of the front windshield is needed, the defrosting effect is increased as compared with when the defrosting is not needed.

摘要： An air conditioner capable of enhancing responsivity of a blowout temperature of conditioned air while preventing occurrence of an overshoot or undershoot condition of the blowout temperature when a user gives an instruction to change the blowout temperature in a dehumidifying operation mode. In a control state, if a set temperature level is adjusted to increase a blowout temperature of conditioned air by increasing the target condenser outlet temperature, the rotating speed of the refrigerant compressor is increased, while the restriction opening of the heating expansion valve is maintained. Thus, the condenser outlet temperature is regulated to the target temperature with minimal undershoot or overshoot of the target temperature.
